How to solve these injection mold breakdowns?
The working state of the injection mold in the molding process directly affects the quality performance and production efficiency of the injection product. In the molding process, it is common to meet breakdowns, and how to solve the following defects?
Difficulty in product separation
In the injection molding process, if it is hard for the product to separate from the channel part, generally the operator needs to cut it manually, which seriously affects the mass production. The main reason for these defects is that the gate finish is not smooth. In this regard, we should choose the standard parts to ensure that the gate finish can meet the requirements.
Poor cooling effect
The cooling system of the injection mold is another defect that influences the product quality and production efficiency. If the cooling system is unreasonable, it will be easy to generate the defects such as deformation, at the same time, it will cause the mold to overheat and affect the normal production.
The design of the cooling system of the mold needs to be designed by the actual product structure, especially for some heavy mold.
Movable mold bending
In the injection molding process, the melted plastic in the cavity will generate huge backpressure. If we adopt low-strength steel, the movable half will bend after a certain period. We must choose high-quality steel as the raw material and expand the thickness to ensure that it can stand the force.
Guide pin
The guide pin mainly plays a guiding function in the injection mold to ensure that the mold core and cavity do not contact each other under any circumstances, and the guide pin cannot be used as a stressed part.
