Embodiment

[0017] Such as Figure 1~4 As shown, the mold uses a core sleeve formed by the head of the compression pin, which is used to clamp the compression pin 1, and includes a core set 2. The core set 2 is a double split type, and is matched by two symmetrically arranged cores 3. Composition, a countersunk hole 4 for placing the compression pin 1 is formed at the matching place of the core set 2, and a mold sleeve 5 for clamping the core set 2 is set on the outer wall of the core set 2, and the mold sleeve 5 is Cuboid shape, the top of the front and back of the mold cover 5 has a gap 52 that runs through the front and back, the middle part of the mold cover 5 has a notch 51, the section of the notch 51 is trapezoidal, the core group 2 is trapezoidal shape, the core group 2 and the mold The notch 51 of the cover 5 is a profile connection, and the two edges of the large end surface of the core group 2 are symmetrically provided with sockets 21, and the inclination angle and direction o...

Abstract

The invention relates to the technical field of dies, in particularly to a die sleeve of die cores for a pressing pin head part molding die. The die sleeve of the die cores for the pressing pin head part molding die is used for clamping a pressing pin and comprises a die core set, wherein the die core set is two-breaking-type and is formed by two die cores which are arranged symmetrically. A counter bore which is used for placing the pressing pin is formed in the position of the die core set matched, and a die sleeve which is used for clamping the die core set is sleeved on the outer wall of the die core set. By the adoption of the two-breaking-type die core set, the pressing pin is clamped in the die core set, due to the fact that the die core set is ladder-shaped, a function that the die core set is clamped is achieved through the die core set in molded surface connection with the die sleeve, simultaneously the die core set is convenient to remove, so that the pressing pin is convenient to take out. The die sleeve of the die cores for the pressing pin head part molding die is simple in structure, can be shared in various processes of the pressing pin head part molding die, the other clamping dies do not need to develop, the cost is reduced, and meanwhile the pressing pin is convenient to take out, and the efficiency is added.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a mold core mold sleeve for a compression pin head forming mold. Background technique [0002] In the automobile industry, suspension rods, also known as compression pins, are commonly used on automobile brake ports. The traditional processing of the head of the compression pin requires upsetting, blanking and other processes. Different processes complete the different processing of the head of the compression pin. Since the compression pin is a rod part, it needs to be clamped and fixed before processing to ensure the quality of the product. However, in traditional processing, the mold for forming and clamping the head of the compression pin has poor clamping effect. At the same time, when the compression pin is processed in different processes, different clamping molds are required, which brings about cost problems, and the blanking of the compression pin is also troublesome in ...
