Description

[Technical Field]

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

[0002] Magnesium alloys have a relatively low density among commonly used metal materials, and can be molded into parts with complex curved surfaces and structures using die casting molds, thus meeting the requirements for product lightweighting.

[0003] Magnesium alloys have a relatively low modulus of elasticity, which results in weak rigidity and load-bearing capacity in some structural applications, leading to deformation.

[0004] In view of this, it is necessary to provide a positioning structure for pre-embedded parts in die casting molds and its usage method to solve the above problems. [Summary of the Invention]

[0005] The technical problem this invention aims to solve is that magnesium alloys have a relatively low elastic modulus, resulting in weak rigidity and load-bearing capacity in some structural applications, leading to deformation. Therefore, this invention provides a positioning structure for embedded parts in die-casting molds and its usage method to address the above-mentioned problem.

[0006] The solution to the technical problem of this invention is: a positioning structure for embedded parts in a die-casting mold, comprising:

[0007] Placement slots: At least one set of placement slots is provided on the male mold core or female mold core;

[0008] An embedded part is set inside a magnesium alloy. The embedded part and the magnesium alloy are formed by die casting. At least one set of first structures is provided on the outer end face of the embedded part. One set of structures includes two structures, which are arranged in a balanced and symmetrical manner. The first structure extends out of the magnesium alloy to the outside of the embedded part. The part of the first structure extending out of the magnesium alloy is set in the placement groove, and the part of the first structure extending out of the magnesium alloy is provided with positioning holes.

[0009] The positioning component is fixedly connected to the female mold core and is used to position the embedded part. Since the female mold core does not move, the embedded part is relatively stable. The male mold core has a positioning groove at the position corresponding to the positioning component. When in use, the positioning component passes through the positioning hole on the embedded part and then connects with the positioning groove.

[0010] Preferably, the outer end face of the embedded part is provided with a second structure, which is used to ensure that the embedded part is balanced and supported in the mold when forming a long magnesium alloy.

[0011] Preferably, the thickness of the embedded part includes, but is not limited to, 1 / 4 of the thickness of the magnesium alloy.

[0012] Preferably, the material of the embedded part includes, but is not limited to, steel.

[0013] Preferably, the positioning element includes, but is not limited to, a positioning pin.

[0014] In addition, the present invention also provides a method for using a positioning structure for embedded parts in a die-casting mold, comprising:

[0015] S1: A positioning component is installed inside the female mold core, and a positioning groove is provided at the corresponding position inside the male mold core;

[0016] S2: The embedded parts are preheated before being placed into the die-casting mold to prevent the broth from cooling down rapidly when it comes into contact with the embedded parts during the filling process;

[0017] S3: The embedded part is clamped into the female mold core using a jig. The embedded part is positioned by the positioning part in the female mold core cooperating with the positioning hole of the embedded part. When the mold is closed, the positioning part is connected with the positioning groove in the male mold core.

[0018] S4: Take out the molded finished product and remove the first structure extending from the finished product through machining to obtain the final magnesium alloy product.

[0019] The beneficial effects of this invention are that it provides a positioning structure for a die-casting mold embedded part and its usage method. The embedded part has at least one set of first structures on its outer end face. Each set of structures includes two structures arranged in a balanced and symmetrical manner. The portion of the first structure extending out of the magnesium alloy has a positioning hole for cooperating with a positioning component in the master mold core to position the embedded part. The magnesium alloy formed by this structure has a complex appearance and structure, while having a higher compressive load-bearing capacity than magnesium alloy and a weight less than steel, thus meeting the requirements for lightweight products.
