Description

Technical Field

[0001] This utility model relates to an improvement of a component of a plastic molding die. Background Technology

[0002] Plastic molding dies can be used to mold electrical appliance casings, mobile phone casings, and automotive interior parts. These dies are installed inside a plastic molding machine. Larger products often require larger dies, which means larger plastic molding machines are needed.

[0003] When making plastic products like filter cartridge housings, we need to install the hot runner nozzles on the upper part of the mold. Filter cartridge housing molds include an upper fixed plate, an upper template, a lower template, and a mold base. The upper part of the upper template is the hot runner plate. Current hot runner nozzle installation technology involves installing the hot runner nozzles entirely on the upper fixed plate and the hot runner plate.

[0004] These types of molds are relatively tall, and the size of the plastic molding machine is matched to the height of the mold. For example, the Haitian 380T can accommodate molds that are larger and taller than the Haitian 320T.

[0005] However, the existing hot runner nozzles are quite tall. In order to install the hot runner nozzles, we must increase the thickness of the upper fixing plate, which increases the height of the mold and indirectly increases the production cost. Utility Model Content

[0006] To overcome the shortcomings of the current high height of filter cartridge housing molds, this utility model provides a filter cartridge housing molding mold with a hot runner thickness reduction structure.

[0007] The technical solution of this utility model to solve its technical problem is: a filter cartridge shell forming mold with a hot runner thickness reduction structure, including an upper fixed plate, an upper template, and a lower template, the lower template being installed on a mold base; the upper fixed plate is provided with a hot runner nozzle fixing groove, and an auxiliary fixing groove is provided on one side of the hot runner nozzle fixing groove; a hot runner nozzle assembly is provided in the hot runner nozzle fixing groove, the upper part of the hot runner nozzle assembly being exposed; it also includes a hot runner nozzle mounting bracket with an upper flat surface, the hot runner nozzle assembly being fixed in the hot runner nozzle mounting bracket, and the hot runner nozzle mounting bracket being embedded in the auxiliary fixing groove, the upper flat surface of the hot runner nozzle mounting bracket being flush with the upper fixed plate; it also includes a cover shell, the cover shell covering the exposed upper half of the hot runner nozzle assembly, and a lower fixing hole for the cover shell is provided on one side of the hot runner nozzle fixing groove, and an upper fixing hole for the cover shell is also provided on the cover shell; it also includes several fixing screws passing through the upper fixing hole and the lower fixing hole for the cover shell to fix the cover shell to the upper fixed plate; a feed hole is provided on the upper end face of the cover shell. The feed port is also located above the cover, where the injection feed tube enters and connects to the hot runner nozzle.

[0008] To improve installation stability, an end plate is also included, which has a through hole. When the end plate is screwed onto the fixing plate, the cover is exposed in the through hole.

[0009] To reduce the overall mold thickness, the thickness of the end plate is optimized, and the thickness of the end plate is less than one-tenth of that of the upper fixing plate.

[0010] Furthermore, the end plate has a thickness of 2 millimeters.

[0011] To facilitate operation, installation, and adjustment, the end plate is also provided with an operation hole, which is matched and corresponds to the position of the fixing hole and the line hole on the upper fixing hole.

[0012] The cover structure is optimized so that the cover includes three parts: an upper end face, a cover edge, and a lower horizontal edge; the fixing hole on the cover is located on the horizontal edge, and when the end plate is installed on the upper fixing plate, only the upper end face and part of the cover edge are exposed through the hole.

[0013] Furthermore, the upper surface of the cover is circular.

[0014] To facilitate venting, a venting notch is provided on the edge of the cover, and the venting hole of the hot runner nozzle assembly is aligned with the venting notch.

[0015] The structure of the hot runner nozzle mounting bracket is optimized, wherein the hot runner nozzle mounting bracket includes a rounded edge and a junction box wiring encapsulation edge; the auxiliary fixing groove includes two parts: a rounded edge groove and a junction box wiring encapsulation groove located on the side of the hot runner nozzle fixing groove.

[0016] Furthermore, the thickness of the upper fixing plate is less than half the height of the hot runner nozzle assembly.

[0017] Because this utility model has a cover shell, some hot runner nozzle components are installed inside the cover shell, which greatly reduces the overall thickness of the mold. The overall usage method of the mold is the same as that of the component with hot runner nozzle, and will not be described again here.

[0018] The beneficial effects of this utility model are as follows: 1. By adopting the end plate and cover shell structure, the thickness of the upper fixed plate is reduced by half, thereby significantly reducing the maximum thickness of the mold and lowering the mold cost. Before the modification, the mold had to be produced on a Haitian 380T machine. After the modification, the mold thickness is reduced to 676mm, allowing production on a smaller 320T machine, significantly saving production costs and increasing the mold's production applicability. 2. With the cover shell, the hot runner nozzle assembly is easier to maintain and replace directly without disassembling too many internal mold components. This not only improves maintenance efficiency but also avoids problems such as mold structure damage or decreased precision caused by frequent disassembly of internal mold components. At the same time, because maintenance operations are more convenient, there is no need to increase the mold thickness for easier maintenance, which helps to achieve a thinner mold design. 3. After the thickness of the upper fixed plate is reduced, the total amount of mold steel used also decreases, thereby saving materials and increasing the average product output per unit of steel, which is in line with the national energy-saving and incremental plan.
