Description

[Technical Field]

[0001] This invention relates to the field of injection molding technology, and in particular to a positioning structure and positioning method for pre-embedded parts in die casting molds. [Background Technology]

[0002] Die casting molds are characterized by high speed, high pressure, and high temperature. When embedding products, the embedded parts usually need to be heated first. However, due to thermal deformation, the embedded parts are prone to positional deviation after heating, resulting in inaccurate positioning. In addition, when the embedded parts are a single long strip shape during the product molding process, they are prone to obstructing filling and have weak bonding.

[0003] In view of this, it is necessary to provide a positioning structure and positioning method for the embedded parts of the die casting mold to solve the above problems. [Summary of the Invention]

[0004] The technical problem this invention aims to solve is that during die-casting mold injection molding of products, the embedded parts are usually heated first. However, due to thermal deformation, the heated embedded parts are prone to positional deviation, leading to inaccurate positioning. Furthermore, when the embedded parts are a single elongated shape during product molding, they can easily hinder filling and have weak bonding. Therefore, this invention provides a positioning structure and method for embedded parts in die-casting molds to solve the above problems.

[0005] The solution to the technical problem of this invention is: a positioning structure for embedded parts in a die-casting mold, comprising:

[0006] The first clamping hole is provided on the embedded part, and at least one first clamping hole is provided;

[0007] A connecting hole is provided on the embedded part, and at least one connecting hole is provided.

[0008] The second clamping hole is provided on the product and is formed under the clamping of the pre-embedded part on both sides by the clamping component.

[0009] The clamping component includes a first clamping component and a second clamping component. The first clamping component is disposed on the male mold core and has a positioning platform. The second clamping component is disposed on the female mold core and has a positioning hole. The positioning hole cooperates with the positioning platform and is used to clamp the embedded part. The first clamping hole ensures accurate positioning when the product is injection molded.

[0010] A method for positioning embedded parts in a die-casting mold, comprising:

[0011] S1: At least one first clamping hole is opened on the embedded part;

[0012] S2: At least one connecting hole shall be made in the embedded part;

[0013] S3: Clamping components are installed on the male mold core and the female mold core respectively;

[0014] S4: Insert the embedded part into the male mold core, and position the embedded part by cooperating with the clamping part in the male mold core through the first clamping hole;

[0015] S5: The male mold core and the female mold core are joined together, and the clamping parts on them clamp the two sides of the embedded part, and then the product is formed;

[0016] S6: Remove the product and fill the second clamping hole and the contact surface between the clamping part and the embedded part with filler material after the product is formed.

[0017] Preferably, the connecting hole is a round hole or an oblong hole.

[0018] Preferably, the position of the contact surface between the clamping member and the embedded part corresponds to the position of the first clamping hole.

[0019] Preferably, the filling material includes, but is not limited to, a putty agent.

[0020] The beneficial effects of the present invention are that the present invention provides a positioning structure and positioning method for a die-casting mold embedded part, which adopts at least one first clamping hole and a connecting hole on the embedded part. The first clamping hole, under the clamping of the two sides of the clamping part, reduces the overall thermal deformation of the embedded part when it is heated, and ensures accurate positioning during product injection molding. The connecting hole enhances the bonding strength between the product and the embedded part. [Attached Image Description]
