Me pehea te hoko mihini werohanga hainamana

Te korero noa, te nuinga o nga kaihoko kua mahi i roto i te umanga miihini werohanga mo nga tau maha, have the ability to judge for themselves and choose the suitable china miihini werohanga to produce. Heoi, i etahi keehi, ka hiahia pea te kaihoko ki te awhina a te kaihanga ki te whakatau ko tehea miihini werohia hei whakamahi, or even the customer may just have the sample or idea of ​​the product and then ask the manufacturer. whether the machine can be produced or which model is compared.

Hei taapiri, some special products may require special devices such as pressure accumulators, koropiko kati, kōpeketanga weronga, etc., to be produced more efficiently. It can be seen that how to determine the appropriate injection molding machine to produce is an extremely important question. The following information is provided for the convenience of readers.

Ko nga mea nui e pa ana ki te kowhiringa o te miihini werohia ko nga maaka, hua, kirihou, whakaritenga whakarewa, etc.. Na reira, ko nga korero e whai ake nei me kohia, me waatea ranei i mua i te kowhiringa:

◆ Parapara rahi (whanui, teitei, matotoru), taumaha, hoahoa motuhake, etc.. ;

◆ Momo me te nui o te kirihou whakamahia (he rauemi mata kotahi, he maha ranei nga kirihou);

Te rahi o te ahua (roa, whanui, teitei, matotoru), taumaha, etc.. hua werohanga whakarewa;

I muri i te whiwhi i nga korero o runga ake nei, ka taea e koe te whai i nga hikoinga i raro nei ki te whiriwhiri i tetahi miihini werohanga tika:1. Kōwhirihia te tauira tika: ko te tauira me te raupapa e whakawhirinaki ana ki te hua me te kirihou. Na te mea he maha nga momo haina mihini werohanga, he mea tika ki te whakatau tika mai ko wai te miihini whakakikorua werohanga, raupapa ranei me hanga te hua i te tuatahi, penei i nga rauemi mata wera, te bakelite ranei, nga rauemi mata PET ranei. Tae, rua-tae, tae maha, taupatupatu, he ranu ranu ranei, etc.. Hei taapiri, ko etahi hua e hiahia ana ki nga ahuatanga penei i te tino pumau (koropiko kati), tika teitei, ahi tino tiketike, te pehanga pupuhi teitei, te whakaputa tere ranei (koropiko maha), and a suitable series must also be selected for production.

2. Ka taea te tuku ki raro: the mold size determines whether the “large column inside distance”, “matotoru pokepokea ai”, “iti te rahi o te pokepokea ai” me “rahi pereti pokepokea” of the machine are suitable to ensure that the mold can be put down.

◆ The width and height of the mold must be less than or at least one side smaller than the inside distance of the large column;

◆ The width and height of the mold must correspond to the minimum mold size recommended by the injection molding machine and is too small.

3. It can be obtained: the mold and the final product determine whether the “mold opening strokes” me “mold strokes” are sufficient to remove the final product.

◆ The opening stroke of the mold must be at least twice the height of the final product in the direction of opening and closing of the mold, a me whakauru te roa o te whakarewanga;

4. Ko te waahanga awhi ka taea te maukati i te miihini werohia me nui “kaha clamping” kia kore ai e tuwhera te pokepokea ai. Ko te tatauranga o te hiahia awhi mo te kaha e whai ake nei:

◆ Tātaihia te rohe matapae o te hua kua oti i te ahunga o te pokepokea whakahuri mai i te rahi o te ahua o te hua kua oti;

◆Te kaha tautoko mould = rohe matapae o te hua oti i roto i te ahunga o te pokepokea huri (cm2) × te maha o nga kohanga pokepokea × te pehanga i roto i te pokepokea ai (kg/cm2);

◆Ko te pehanga i roto i te pokepoke he rereke ki te rauemi mata, ā, ko te 350~400kg/cm2 te rauemi mata whānui;

◆Ko te kaha awhi o te miihini me nui ake i te kaha awhi, a mo te whakaaro ki te ahuru, ko te kaha o te clamping o te miihini te tikanga 1.17 wa nui ake i te kaha o te clamping.

5. Kopere katoa: Whakatauhia nga mea e hiahiatia ana “rōrahi werohanga” mai i te taumaha o te hua kua oti me te maha o nga kohao pokepokea ai ka tohua te mea tika “diameter diameter”.

◆Te maha o nga kohao pokepokea ai (kotahi pokepokea me te maha o nga kohao) me whakaaro ki te tatau i te taumaha o te hua kua oti;

◆Mo te pai o te pumau, me rite te rōrahi werohanga 1.35 nga wa te taumaha o te hua kua oti, ko te, ko te taimaha o te hua kua oti i roto 75% Tuhinga o mua.

6. He pai te weronga: nga tikanga o “ōwehenga kōpeketanga tīwiri” me “pehanga weronga” ka whakatauhia e te kirihou. Ko etahi o nga miihini hangarau e hiahia ana kia teitei ake te pehanga werohanga me te tika o te whakaheke i te koporetanga hoahoa kia pai ake ai nga hua o te pokepoke. Na reira, kia pai ake ai te kopere o te hua kua oti, me whai whakaaro ano nga whakaritenga pehanga werohanga me nga take ōwehenga kōpeketanga ina kōwhiri i te tīwiri. .

7.7. Te pupuhi tere: me te whakapumautanga o “tere kopere”. Ko etahi o nga hua kua oti te hiahia kia nui te weronga me te weronga tere mo te whakarewa pumau, penei i nga hua ultra-angiangi kua oti. I tenei keehi, akene he mea tika kia whakau mena kua tau te tere weronga me te tere weronga o te miihini, ana mena ka hiahiatia kia whakakotahihia ki nga whakaeminga nekehanga, mana-koropiko kati me etahi atu taputapu. Te korero noa, i raro i nga tikanga ano, he tīwiri ka taea te whakarato i te pēhanga weronga teitei ake i te nuinga o te waa he tere te perehana o raro, i te anga ke, he tīwiri ka taea te whakawhiwhi i te pēhanga weronga o raro i te nuinga o te waa he tere ake te tere. Na reira, i te wa e kowhiri ana koe i te diameter tīwiri, te nui o te weronga, pehanga weronga me te tere weronga (tere weronga) me matua whakaaro-whiti ka kowhiria.

Hei taapiri, ka taea te whakamahi i te hoahoa koropiko maha-ki te whakapoto i te wa whakarewa me nga mahi whakaranu kua honoa. I muri i nga mahi i runga ake nei, i roto i te kaupapa, he miihini miihini weronga e tutuki ana i nga whakaritenga ka taea te whakatau, engari tera ano etahi take motuhake me whakaaro:

◆Ko te raruraru o te rite te rahi:

I raro i etahi tikanga motuhake, ko te miihini a te kaihoko, ko tana hua ranei, he iti pea te pokepokea ai engari he nui te pu, he rahinga whakarewa nui ranei engari he iti noa te pu. I tenei keehi, ko nga whakaritenga paerewa kua tohua e te kaiwhakanao kaore pea i te waatea. Hei whakatutuki i nga hiahia o nga kaihoko, pera-ka karanga “rahi taurite” me kawe, ko te, “pakitara nui pere iti” ranei “pakitara iti pere nui”. Te mea e kiia nei “pakitara nui me te weronga iti” e pa ana ki te paerewa taketake o te wae whakamate paitini me te tīwiri werohanga iti ake. I te anga ke, te “pakitara iti me te weronga nui” e pa ana ki te peera o te peera paerewa taketake me te kopere weronga nui ake. Ae ra, tera pea he maha nga rereketanga rereke i waenga i te werohanga pokepoke me te weronga.

I te whakamahinga tuuturu, he maha tonu nga kaihoko ka tono ki te hoko i nga mea e kiia nei “miihini tere-tere” ranei “miihini tere”. Te korero noa, hei taapiri ki nga hiahia o te hua ake, ko te nuinga o nga whaainga ko te whakapoto i te huringa whakarewa me te whakapiki i te putanga mo ia wahanga waeine, na te whakaheke i nga utu whakaputa me te whakapai ake i te whakataetae. Te tikanga, ki te whakatutuki i te kaupapa kua whakahuatia ake nei, he maha nga huarahi:

1. Kia tere te tere weronga: whakanui i te miihini me te papu, te taapiri ranei i te kaitautoko pehanga (pai ake te kati i te koropiko);
2. Whakanuia te tere o te kai: whakanuia te motini me te papu, whakaiti ranei i te miihini waipiro whangai kia tere te tere o te kopore;
3. Pūnaha maha-koropiko: ka tango i te hoahoa-rua-toru-toru ranei ki te mahi i nga mahi whakahiato i te wa kotahi ki te whakapoto i te wa hangai.;
4. Whakanuia te huarahi wai pokepokea hei whakapai ake i te kakama whakamahana o te pokepokea ai.
