Injection mold factory introduce Injection mould Assembly process

1. Preparation before installation of injection mold factory

Confirm the cooling water channel. The screw depth in the plate is 1.5-1.8 times of the screw diameter. If the tightening is not sufficient, it is easy to slide, and there is a risk that the mold will fall. confirm

Operators, materials, tools, documents, equipment, auxiliary machines, etc. What is necessary for production is complete.

2. Method of hanging mold in injection mold factory

When the hanging mold is not horizontal, the mold cavity will have different steps before and after the mold installation. For the production of complex products, there will be low concentricity, poor channel and tooth shape

Poor precision. Walking distance

When installing the mold, attention must be paid to this problem: when the mold is placed and pushed to a smaller position, the mold clamping stops. Loosen and tighten the lifting ring. The above modes are parameters

Because the front die has a locating ring. When looking at the rear, the position of the mold cavity is consistent when the level of the current mold is excellent. Continue to hold the mold until it is completed, but do not

To activate the high pressure. Good (When closing the upper mold at one time, do not use the high pressure first, and confirm that the mold can be normal before starting the high pressure).

3. Tightening method of injection mold factory

Low temperature mold, that is, mold temperature is lower than 50 degrees, can withstand high pressure to start. The front and rear dies are fastened diagonally. 8 screws can be tightened. When the mold temperature is higher than 50

The screw should not be too tight before reaching the mold temperature. When the mold temperature reaches, start the high pressure and tighten the screws diagonally.

As the temperature rises, the mold material will expand and increase in volume. When the mold temperature is high, it is more obvious that if the screws are tightened before the temperature rises

The service life of the die and the precision of the die have some effects.

4. Use adhesive materials in injection mold factories.

When the thickness of the mold is not enough, the template needs to be added. When the mold temperature is high, the heat shield is installed between the machine plate and the mold. Whether it is formwork or heat shield, flat

The integer should be as small as possible.

If the flatness is large, the front and rear molds of the mold are not parallel, and there is a difference after the high pressure is turned off, which will affect the quality of the product. When the mold temperature reaches the set value

Verify the actual mold temperature and adjust the mold thickness.
