Description

Technical Field

[0001] The utility model relates to the technical field of plastic products, in particular to an injection mold for a pipeline special-shaped supporting component. Background Art

[0002] Injection molds are tools for producing plastic products; they are also tools that give plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain parts with complex shapes. Specifically, it refers to the process of injecting heated and melted plastic into the mold cavity under high pressure by an injection molding machine, and then cooling and solidifying to obtain a molded product.

[0003] Usually, injection molded pipes are straight pipes, which usually need to be fixed during the pipe laying process. For example, a U-shaped pipe clamp is used to fix the straight pipe to the wall. However, in some special environments, multiple straight pipes with different directions need to be fixed. If each pipe is fixed with a U-shaped pipe clamp, not only a large number of pipe clamps are required, but also the operation is more cumbersome for the installer.

[0004] At present, there is a special-shaped support component for pipelines on the market, such as Figure 6 As shown, the special-shaped support component includes a support sleeve A and a connecting block B. The connecting block B is connected to the circumferential surface of the support sleeve A. One or more mounting holes C are provided on the connecting block B. The axial direction of the mounting hole C is not parallel to the axial direction of the support sleeve A. Therefore, this special-shaped support component can support multiple straight pipes with different directions. Therefore, this special-shaped support component is convenient for installing multiple straight pipes. However, due to structural factors, the above-mentioned special-shaped support component is currently made of metal material, and the connecting block and the support sleeve are fixed by welding. Therefore, this special-shaped support component is not only costly, but also has a cumbersome manufacturing process. Utility Model Content

[0005] The utility model provides an injection mold for a pipeline special-shaped supporting component. The special-shaped supporting component is prepared by injection molding using the utility model, which is beneficial to reducing production costs.

[0006] The technical solutions to the above problems are as follows:

[0007] The injection mold of the pipeline special-shaped support component includes an upper mold assembly and a lower mold assembly matched with the upper mold assembly, the upper mold assembly includes an upper mold base and an upper mold core, the upper mold base is provided with a first accommodating cavity, the upper mold core is located in the first accommodating cavity and is fixed to the upper mold base, and the upper mold base and the upper mold core are provided with a first injection channel;

After the upper mold core and the lower mold core are molded together, the upper mold cavity and the column cooperate, and the surface of the upper mold core cooperates with the lower mold cavity to form an injection mold cavity for the special-shaped support component. The first injection channel and the second injection channel are combined to form an injection channel.

[0011] Furthermore, the upper die core comprises an upper die core body and an upper pressing block, the upper die core body is provided with a clearance recess, and the upper pressing block is located on one side of the clearance recess;

[0012] The lower die core comprises a lower die core body and an insert assembly. After the insert assembly is fixed to the lower die core body, a portion of the insert assembly extends into the lower die cavity to form a mounting hole on the special-shaped pipe support component.

[0013] After the upper mold core is molded with the lower mold core, the upper pressing block is pressed on the insert assembly, and a part of the insert assembly is inserted into the clearance recess.

[0014] Furthermore, the insert assembly includes a fixed seat, an edge sealing block, an insert connecting seat, and a connecting column. The fixed seat is fixed to the lower mold seat, the edge sealing block is fixed to the fixed seat, the edge sealing block cooperates with the second injection channel, the insert connecting seat is fixed to the edge sealing block, and the insert connecting seat passes through the edge sealing block and extends into the lower mold cavity.

[0015] Furthermore, a positioning rod is provided on the upper pressure block, and the axial direction of the positioning rod is inclined to the axial direction of the upper mold assembly. A first through hole is provided on the fixed seat, and the axial direction of the first through hole is inclined to the axial direction of the lower mold assembly. A clearance hole is provided on the lower mold seat. When the upper mold assembly and the upper mold assembly are closed, the positioning rod passes through the first through hole and is inserted into the clearance hole.

[0016] Furthermore, the upper mold assembly is provided with a first cooling channel, and the lower mold assembly is provided with a second cooling channel.

[0017] When the utility model is used to manufacture a special-shaped support component, the upper mold assembly and the lower mold assembly are first molded together, so that the first injection channel and the second injection channel are combined to form an injection channel, and the surface of the upper mold core and the lower mold cavity are matched to form an injection mold cavity for the special-shaped support component, and then the heated and melted injection material is injected into the injection channel through the first injection channel. After the injection material is added, the special-shaped support component can be obtained by cooling and shaping. It can be seen that the use of the utility model to prepare a special-shaped support component by injection molding not only simplifies the process, but also reduces the material cost and labor cost compared with the prior art.
