Dongguan Ruiqingxuan Plastic Mould Products Co., Ltd. isHigh-quality mold injection manufacturer, The factory is committed to providing high-quality and competitive products to customers at home and abroad in a short time. It is our goal to become the first supplier and permanent partner of customers. We have established an advanced CAD/system and a centralized management system to realize the sharing and high-speed transmission of information resources within the company, greatly improving the integration process of mold design and processing, and provide a variety of high-precision, sophisticated mold design, Manufacturing provides a strong guarantee. The company produces 500 sets of molds annually.

Today, Ruiqingxuan sorted out several suggestions that need to be paid attention to when installing mold injection:

1. Preparation before installation in the injection mold factory

Confirm the cooling water circuit, the depth of screwing the screw into the machine board is 1.5-1.8 times the diameter of the screw. If the screw is insufficient, the teeth will slip easily and there is a risk that the mold will fall. Confirm whether the operators, materials, tools, documents, auxiliary equipment, etc. required for production are complete.

2. The method of hanging the mold in the injection mold factory

When the hanging mold is not level, the mold cavity before and after the installed mold will have different steps. For the production of precision products, there will be poor concentricity, poor step, poor tooth profile accuracy, and poor distance.

When installing the mold, we must pay attention to this problem. When the hanging mold enters and closes until the hand can push a small position, stop the mold clamping. Loosen and tighten the lifting ring, using the previous mold as the reference (because the front mold is fixed by the positioning ring), watch the back mold part, when the level of the front mold is extremely good, the mold cavity position is consistent, continue to close the mold to completion, but do not start the high pressure it is good. (The upper mold must be closed for the first time without applying high pressure. After confirming that the mold can be properly closed, the high pressure can be applied).

3. The method of screwing in the injection mold factory

For molds with a low temperature, that is, a mold temperature below 50 degrees, when the mold is closed to a high pressure start, the front and rear molds must be tightened diagonally. 8 screws are enough. When the mold temperature is above 50 degrees, the screws should not be tightened too much before the mold temperature is reached. After the mold temperature reaches the high pressure start, tighten the screws diagonally.

The mold material will swell and increase in volume with the increase of temperature. It is more obvious when the mold temperature is high. If the screws are tightened before the temperature rises, it will have a certain impact on the life of the mold and the accuracy of the mold.

4. Use of attached materials in injection mold factory

When the thickness of the mold is not enough, it is necessary to install a template. When the mold temperature is high, install an insulation board between the machine plate and the mold as much as possible. Whether it is a template or an insulation board, its flatness must be as small as possible.

If the flatness is large, the front and back molds of the mold are not parallel, and there is a difference after the high pressure is closed, which affects the quality of the product. When the mold temperature reaches the set value, check the actual temperature of the mold, and perform a mold thickness adjustment.
