The cavity of the half mold is composed of two or more sliders. At the time of mold opening, the slider simultaneously achieves side parting. The stroke of the side core pulling of the half mold is generally small. Half mold can be divided into: fixed mode Half blocks and moving mode Half blocks. Both structures have their own advantages and disadvantages, and can be used for different products. The fixed mold half slider structure is relatively uncomplicated. In the design, pay attention to factors such as stroke, guide block, drive block and so on. The above notes can help you design better.

The hydraulic cylinder can realize the lateral parting or core pulling of the injection mold. Its movement is smooth, flexible and simple. Not limited by mold opening time and ejection time.
How to design a reliable hydraulic cylinder mechanism? In addition to the theoretical knowledge of the cylinder, these 8 points should also be considered in the design.

Whether the mold is set with an air venting has a great influence on the quality of plastic parts. For thin-wall plastic parts, small plastic parts or precision parts, the air venting is a crucial point. And in the same plastic part, the part away from the gate position needs to be designed with air venting.

Mold design should understand the working principle of the part. It is necessary to know how to design properly so as to avoid problems with the designed mold. The existence of these problems will seriously affect the quality of the mold. We need to pay enough attention.

Mold designers need to pay attention to some details of mold structure and part design. Details determine success or failure. Of course attention to detail requires level and experience. Don’t worry, this article contains 12 general details. Get these details to help your design.
