According to the structural characteristics of plastic moulding, the side core-pulling mechanisms are divided into the following six categories: 1. The side core-pulling mechanism of "slider + guide...

The picture 1 shows a typical guide pin driven slider parting and core-pulling mechanism, we will talk about the composition and function of the lateral core-pulling mechanism. 1. Lateral forming...

1. After the slider core pulls out, the length of staying in the guide pin slot should not be less than 2/3 of the total length of the slider, for special cases, the slider slot can be partially...

9. The molding parting surface of the slider molding should be made as a shut-off surface as possible, and the width of the shut-off part should be at least 8mm, and do not make a shut-off surface;...

1. Normally, all the insertion slopes of the slider are not allowed to be less than 3° to prevent excessive self-locking force and scratched; 2. The angle of the locking surface must be bigger than...

1. The T slot of slot should be designed according to the picture 1, If there is a relatively high slider, the slider T slot is not high enough which will cause the center of gravity to be unstable,...

1. The wear plate of slider requires hardening treatment, with a hardness of 45-48HRC; 2. The friction surface of the wear plate is required to be 1.0mm higher than the slider surface (see picture-1);...

Processing size: 1. ØD2=ØD+2 2. Ll = total spring length (L) - preload value of spring (N) - slider core pulling distance (L2) Spring length calculation: (refer to picture 1 for length calculation)...
