Coñecemento da máquina de moldaxe por inxección

Calquera persoa que poida axustar a máquina coñece os cinco elementos do moldeado por inxección, pero sobre quen se constrúen estes cinco elementos? O máis importante é a máquina de moldeo por inxección.

Por suposto, tamén hai algún equipamento auxiliar (como controlador de temperatura do molde, caixa de control de temperatura, etc.) para axudar a completalo. Entón, canto podes saber sobre o rendemento da máquina de moldaxe por inxección que depuras?

Por exemplo, para un produto, nas mesmas condicións que o molde de materia prima, a máquina de moldeo por inxección A pódese depurar, pero a máquina de moldeo por inxección B non se pode depurar.

Cal é a razón? Quizais algúns técnicos só saiban que a máquina B non funciona. Algunha vez pensou en atopar a causa raíz para resolver este problema? Entón, para axudarche a atopar o motivo, é o punto clave do meu artigo para compartir contigo, mercadorías secas, Espero que vos guste.
En moldeo por inxección, só hai un que ten unha rica experiencia. Ninguén pode facer todo e comprender todos os produtos. Novos problemas aparecen constantemente na produción. Os técnicos deben seguir analizando e resolvendo problemas. Agora recoméndase o moldeado por inxección científica. Os técnicos son inseparables, polo que os técnicos son a base da produción de moldaxe por inxección.

Algunhas empresas non prestan moita atención aos técnicos, e o persoal técnico non pode ser remunerado. Espero que algún día poidamos usar a tecnoloxía para viaxar polo mundo como Alemaña. Espero que os xefes vexan. O seu técnico pode aumentar o capital de procesamento! Tamén espero que os técnicos aprendan un pouco máis de tecnoloxía, e axustar a máquina para evitar desvíos. Déixeme dicirche como avaliar a máquina de moldaxe por inxección.

Cada un máquina de moldaxe por inxección ten o rendemento de cada máquina de moldaxe por inxección, e a nova máquina de moldeo por inxección que acaba de saír da fábrica é a mesma, pero a diferenza é insignificante, especialmente algunhas antigas máquinas de moldaxe por inxección, algunhas máquinas de moldeo por inxección de segunda man que compraches de volta, you don’t even know that others have repaired it.

Where, so when every technician arrives in a new company, he can’t get started quickly. The performance of the equipment can only be mastered through constant exploration. Then we will now evaluate the performance of the injection molding machine and make a resume. Every technician It can be seen that it can also improve the efficiency of tuning.
1.The temperature is very simple.

Everyone knows that the temperature is visible in the injection molding machine. In the current injection molding machine, there are set temperature and actual temperature. The deviation of temperature can be seen at a glance, and of course there is also a broken temperature sensor.

Si, we can see the temperature level from the flow properties of the glue through the state of the glue. I will not introduce them one by one here. The main ones are the following.

2. 2. The injection pressure is invisible to the older injection molding machine. There is only a general pressure gauge. Some technicians do not look at this pressure gauge.

When you adjust the injection pressure from 50 a 90, the product does not change. Don’t doubt the injection pressure linearity of this injection molding machine is wrong? There are several ways to do this. I will introduce the use of the shooting platform to test the pressure.

Primeira, adjust the shooting table to the end, set the shooting speed to 50% of the maximum shooting speed, and the pressure of the shooting table to retract from 10 Or start at 140 (some injection molding machines limit the maximum speed and pressure of the injection station at the factory, this needs to be adjusted in the parameters)

the order does not matter, press and hold the injection station to retract until the pressure can be read on the pressure gauge, 10. 20 .30 ……140 Set the pressure in sequence like this, record the reading corresponding to each pressure on the table (attached below), it should be in an increasing or decreasing state.

(Here is something I encountered. I was in a company before, and the injection speed of an injection molding machine was the same from 10 a 40. This is the A injection molding machine mentioned above and the B injection molding machine. The reason can’t be debugged, por suposto, there is more than one reason.)

3. O velocidade de inxección is invisible on the injection molding machine. Just like the example above, the speed from 10 a 40 is the same. The technician can’t adjust the product. We can calculate the speed through the evaluation. The injection pressure is adjusted to 50% of the total pressure, and the storage position is 60%-70% of the total storage position. Here is empty injection, no storage is required.

The time is set for 1-2 seconds according to the tonnage of the injection molding machine, and then loosened The exit setting is the same as normal production, the injection speed starts from 10, long press the injection button, read out the data corresponding to the injection speed from 10. 20. 30…140, and record it on the table.

4. Backflow Everyone knows that this is the key point when adjusting the machine. If there is a problem with the backflow, the product will be unsaturated, the product density will not meet the requirements, the product with high deformation requirements cannot be transferred, the product weight will be unstable, and many other problems .

We first find a copper block or aluminum block, set the injection time to 30 segundos, the injection pressure is 50% of the total pressure, the speed is 50% of the total speed, and the storage is 70%-80% of the total storage.

When the material is full, use the nozzle to hold the copper block or aluminum block, as long as there is no leakage, press and hold the injection button until the end position of the injection is recorded once at 15 segundos, once at 25 segundos, and tested twice, and recorded to the table on.

5. Parallelism Clamping Force If an máquina de moldaxe por inxección moves the template and the fixed template is not parallel, then the product may be ejected while flashing, then we need to adjust the template, there are many adjustment methods, In the machine repair center in the factory, the technicians only need to find the reason and tell them the problem.

Primeira, we need to use the rod-meter type of the hundred-point watch band, next to the 4 Corinthian pillars, and measure the data for comparison. I know how to adjust the parallelism, and the other is to measure the clamping force. A clamping force tester is used here. This depends on the company’s needs (sobre 40,000 a 50,000 RMB), and it can generate the tensile force or tension of the Collin column , Adjusted together with the parallelism, this will not be introduced.

6. Record all the above data on the table. The table below I have a function formula, which can automatically get the grade of the injection molding machine. Even if the grade cannot be obtained, convertelo nun currículo da máquina de moldeo por inxección.

Unha vez que hai un grupo deste tipo, os datos poden mostrar o rendemento da máquina de moldeo por inxección. Para o mantemento dos equipos ou axuste dos parámetros de función interna do máquina de moldaxe por inxección, segue sendo moi eficiente para nós axustar a máquina e evitar rodeos.
