Abstract
Description
Technical Field
[0001] This utility model belongs to the field of injection mold technology, and relates to injection molds for cat litter box plastic parts. Background Technology
[0002] With the changing attitudes of modern pet owners, "scientific pet care" and "refined pet care" are becoming trends, and pet supplies are constantly evolving. Among these, litter boxes are indispensable for cat lovers. The production of litter boxes requires injection molds to create the outer shell, which is then assembled. Existing technology, such as the injection mold disclosed in patent number CN202321871434.X, involves installing the mold and connecting it to an external injection pipe. The injection material enters the mold cavity through the injection pipe, producing a litter box shell of the corresponding shape according to the shape of the mold shell. The efficiency of injection is increased by setting up connecting mechanisms one and two. Control blocks, control plates, and control holes facilitate the opening and closing control of the injection mechanism, making demolding convenient.
[0003] However, the aforementioned injection mold has a drawback in use: it cannot effectively cool the raw materials injected at high temperatures, which greatly prolongs the mold opening time and reduces production efficiency. Therefore, we designed an injection mold for cat litter box plastic parts. Summary of the Invention
[0004] The purpose of this invention is to provide an injection mold for cat litter box plastic parts to solve the problems mentioned in the background art.
[0005] The objective of this utility model can be achieved through the following technical solution: An injection mold for a cat litter box includes an upper injection mold body, a lower injection mold body, and a cat litter box cavity. The upper injection mold body and the lower injection mold body are connected by a mold assembly. A mold support base is provided at the bottom of the lower injection mold body. A condenser tube rack is provided inside the mold support base. A contact heat dissipation seat, which is embedded and connected to the lower injection mold body, is mounted on the top of the condenser tube rack. The cat litter box cavity is located in the middle of the contact heat dissipation seat. External pipes are provided at both pipe sections of the condenser tube rack. Cooling fin cylinders are installed on the walls of both external pipes. Semiconductor cooling fins, electrically connected to an external power supply, are installed in the middle of both cooling fin cylinders. The tail ends of both external pipes pass through the mold support base and are connected to an inlet pipe section and a drain pipe section.
[0006] In the above-mentioned injection mold for cat litter box plastic parts, a clamping component is provided at the corner of the upper injection mold body. The clamping component includes a right-angle clamping block, a tenon column connecting seat and a tenon column. A notch is opened at the corner of the upper injection mold body. The right-angle clamping block is fixed inside the notch and is mortised and tenoned with the tenon column. The tenon column is located at the end of the lower injection mold body through the tenon column connecting seat.
[0007] In the injection mold of the aforementioned cat litter box plastic part, the clamping assembly further includes a fastening bolt, which passes through a tenon and is connected to a right-angle clamping block.
[0008] In the injection mold of the aforementioned cat litter box plastic part, a guide rail is installed on one side of the mold support base, and a sliding seat is installed at the top of the guide rail. The sliding seat is connected to the side of the injection mold lower body.
[0009] In the aforementioned injection mold for the cat litter box plastic part, positioning brackets are installed around the bottom of the upper injection mold body, and corresponding slots are opened around the top of the lower injection mold body.
[0010] In the above-mentioned injection mold for the cat litter box, a sprue plate is embedded at the center of the top of the upper injection mold body, and the hot glue channel of the sprue plate corresponds to the cat litter box mold cavity.
[0011] Compared with the prior art, the advantages of the injection mold for the cat litter box plastic part of this utility model are as follows: By setting a condenser tube rack inside the mold support base, and installing a contact heat dissipation seat that is embedded and connected to the lower injection mold body at the top of the condenser tube rack, the cat litter box mold cavity is located in the middle of the contact heat dissipation seat. External pipes are set at both pipe sections of the condenser tube rack, and cooling chip cylinders with semiconductor cooling chips are installed on the pipe walls of the two external pipes. In this way, the cat litter box mold cavity can be cooled by cooling water, which accelerates the molding rate of the blank inside the cat litter box mold cavity, greatly improves the cooling efficiency, and speeds up the production progress. By setting a clamping component including a right-angle clamping block, a tenon column connecting seat and a tenon column, the right-angle clamping block is fixed inside the notch and is tenon-tenon connected to the tenon column. The tenon column is located at the end of the lower injection mold body through the tenon column connecting seat. This can ensure that the upper injection mold body and the lower injection mold body have good strength after mold closing, and avoid the cat litter box mold cavity temperature from being too high, causing the air pressure to rise, which would prevent the upper injection mold body and the lower injection mold body from being unable to be effectively joined.

[0017] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model relates to the injection mold for a cat litter box plastic part;
[0018] Example: The cat litter box injection mold includes an upper injection mold body 1, a lower injection mold body 2, and a cat litter box cavity 8. The upper injection mold body 1 and the lower injection mold body 2 are connected by mold closing. A sprue plate 4 is embedded at the center of the top of the upper injection mold body 1. The hot glue runner of the sprue plate 4 corresponds to the cat litter box cavity 8. A mold support base 3 is provided at the bottom of the lower injection mold body 2. A condenser tube rack 13 is provided inside the mold support base 3. A contact heat sink 7, which is embedded and connected to the lower injection mold body 2, is mounted on the top of the condenser tube rack 13. The cat litter box cavity 8 is located in the middle of the contact heat sink 7. An external pipe circuit 14 is provided at each of the two pipe sections of the condenser tube rack 13. A cooling chip cylinder 15 is installed on the pipe wall of each of the two external pipe circuits 14.

[0019] In this embodiment, in order to ensure good strength after the upper injection mold 1 and the lower injection mold 2 are molded together, and to prevent the temperature of the litter box cavity 8 from being too high and causing an increase in air pressure, which would prevent the upper injection mold 1 and the lower injection mold 2 from effectively joining, a clamping assembly is provided at the corner of the upper injection mold 1. The clamping assembly includes a right-angle clamping block 18, a tenon column connecting seat 19, and a tenon column 20. A notch 17 is opened at the corner of the upper injection mold 1. The right-angle clamping block 18 is fixed inside the notch 17 and is mortised and tenoned with the tenon column 20. The tenon column 20 is located at the end of the lower injection mold 2 through the tenon column connecting seat 19. The clamping assembly also includes a fastening bolt 21, which passes through the tenon column 20 and is connected to the right-angle clamping block 18.
[0020] In this embodiment, in order to facilitate pulling the mold support seat out from the bottom of the injection mold 2 and to facilitate cleaning the inner cavity of the mold support seat 3, a guide rail 11 is installed on one side of the mold support seat 3, and a sliding seat 12 is installed at the top of the guide rail 11. The sliding seat 12 is connected to the side of the injection mold 2.
[0021] In this embodiment, in order to improve the positioning accuracy of the upper injection mold 1 and the lower injection mold 2, positioning brackets 6 are installed around the bottom of the upper injection mold 1, and slots 5 corresponding to the positioning brackets 6 are opened around the top of the lower injection mold 2.
[0022] In use: The upper injection mold 1 and the lower injection mold 2 are closed. The fastening bolts 21 pass through the tenon 20 and are connected to the right-angle clamping block 18 to improve the strength after the mold is closed. The molten raw material is injected into the litter box cavity 8 of the lower injection mold 2 through the sprue plate 4 and the hot glue runner.
