How to set low pressure protection for injection molding machine mold clamping?

The meaning of jekeseni nkhungu protection: it is artificially set during the production process to protect the mold and prevent damage to the mold due to congenital causes and foreign objects. The behavior of mold protection: When setting the mold low pressure protection, where to understand the protection? Kumene, it uses low-pressure protection, ndiye, it will alarm when a foreign body is pressed and will not damage the mold.

The specific approach is as follows:
Kuti
1. First determine which part of the mold should be protected? Such as neutron, core pulling, inserting, sliding block, oblique pin, mold core, thimble, etc..
Kuti
2. Then decide the distance to be set for the low-voltage protection. The contact position of the parts to be protected must be within the distance of the low-voltage protection you set, so that the low-voltage protection will be set. Within the scope of machine monitoring.

Mwachitsanzo, the contact position of the movable mold and the fixed mold is at 30mm during the mold clamping process. According to the dangerous situation, we set the low-pressure protection position at 32mm, so that when the mold is closed to 32mm, it will start to enter the low-pressure protection position. Within effective surveillance.
3. Determine the speed of mold clamping. This speed is also a relatively important parameter. It should not be too fast, but it is adequate. Too fast will produce a certain amount of inertia. The speed of this segment is better to be slow, generally not more than 15%, and the speed is determined later. , Don’t change it arbitrarily.
Kuti
4. The pressure setting is more important. It is better to make the mold just fit into the parting surface contact of the mold with the minimum pressure. Reduce the minimum unit (Kampani ikhoza kusankha kupanga chida chimodzi cha gawolo kuti zitsimikizire kuti zonse zidzawumba momwe zikufunira, 1 pressure unit) and the mold will not fit into the parting. Face contact, use this pressure as the minimum pressure for low-pressure protection (it can be done so that you can put a piece of paper in and make the machine alarm).
Kuti
5. Take the parting surface contact as the new standard, and add 0.1~0.3mm to this position as the high-pressure clamping position. This 0.1~0.3mm (recommended value) is to compensate for the thermal expansion and contraction of the mold material. Kumene, this compensation position can be set smaller, too small may cause frequent low-voltage protection alarms.
Kuti
Zindikirani: This setting may be at the expense of cycle time. Colleagues can set it according to the specific situation, but the above can be used as a general principle. At the same time of setting, pay attention to the Kutentha kwamphamvu must be stable, especially the high jekeseni nkhungu temperature mold thermal expansion, may produce temperature difference, affect the setting. After the low-pressure protection is set, changing the speed of the low-pressure protection at will may cause the set low-pressure protection pressure to be too high, which is the result of inertia.
