The most important molds for stamping processing are convex and concave molds. Next is the discharge plate. The structure of the mold is mainly composed of these three elements as the center. (Figure 1) Basic structure of the mold: The content of Figure 1 is mainly classified based on the following two conditions. 1. Position of convex and concave molds convex mold on top and convex mold on bottom (formal installation); convex mold on bottom and convex mold on top (reverse installation) 2. Is there a d

What is needed for the cooperation between the mold and the component? That's right, it's the guide post, and that's what the editor brings to you today. The guide post can ensure that the mold can move accurately and guide the mold. It is usually cylindrical with shoulders, and the oil grooves will increase with the length of the guide post, up to 8. There are many types of guide posts. According to the guiding direction, they are divided into sliding guide posts and rolling guide posts; according to t

What are the main types of guide posts? 1. According to the different guiding directions, it is divided into: sliding guide post (code SGP), rolling guide post (code SRP). 2. According to the different installation methods, it is divided into: loading and unloading type guide post and press-in type guide post. 3. According to the different places of use, the guide posts are divided into: guide posts for automobile molds, independent guide posts, guide posts for mold bases, and guide posts for strippers. The guid

The working parts and appearance quality of the stamping die are closely related to the wear resistance, crack resistance and adhesion of the die, which directly affect the service life of the die. In particular, the size of the surface roughness has a great influence on the service life of the mold. The wear problem of stamping dies is a problem that every stamping parts manufacturer must face, so how to solve this problem? Yiwei Precision has summarized years of production experience and found that the following

Nitrogen gas springs: Nitrogen gas springs for molds (referred to as die nitrogen springs or nitrogen springs or nitrogen cylinders or nitrogen cylinders) are a new type of high-pressure nitrogen as the working medium Elastic components, which are small in size, large in elasticity, long in stroke, stable in operation, precise in manufacturing, long in service life (one million times), flat in elastic curve, and do not require preloading, etc. It has metal springs, rubber and air cushions, etc. It is difficult to c

As we all know, the gas source of the nitrogen spring is nitrogen, but I wonder if you have thought about why the nitrogen spring should choose nitrogen as the gas source instead of other common gases? The nitrogen gas spring is designed according to the compressibility principle of gas. The nitrogen spring cylinder is filled with a gas to obtain the elastic pressure. The reason for choosing the nitrogen gas spring as the origin of the work has sorted out the following three points for you: 1. First of all, as t
