Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold for toy processing. Background Art

[0002] Toy processing is an industry with a long history. As one of the important tools for toy processing, injection molds play a key role in shaping the appearance and manufacturing details of toys. The water injection port in the injection mold is the outlet for cooling water to enter during the injection molding process. Cooling water is crucial for the normal operation of the injection mold. It can effectively cool the mold, thereby improving production efficiency and product quality. However, the injection molds in the prior art still have certain defects when used and need to be improved;

[0003] In the prior art, the injection mold accelerates the molding of the toy by injecting cooling water during the injection molding of the toy. However, since the cooling water may contain foreign matter such as impurities and particles, these foreign matter will enter the injection mold with the cooling water, block the cooling water pipeline, and affect the cooling effect. At the same time, it reduces the efficiency of toy production and affects the stability of the injection molding process and the product quality. Therefore, a toy processing injection mold is proposed to overcome the above-mentioned defects. Utility Model Content

[0004] The utility model aims to solve the disadvantage of the prior art that it is inconvenient to filter the liquid injection port, and proposes a toy processing injection mold.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A toy processing injection mold comprises a lower mold and an upper mold. The upper mold is matched on the top of the lower mold. A liquid injection port is opened on one side of the lower mold. Connection grooves are opened around the liquid injection port. Second blocks are installed in the four connection grooves.

[0007] The mounting plate has a plurality of filter holes formed therein, the mounting plate is slidably fitted in the liquid injection port, connecting blocks are installed around the mounting plate, four connecting blocks are slidably fitted in the connecting grooves, and first abutment blocks are installed on the four connecting blocks.

[0008] A limiting strip has a first abutting groove and a second abutting groove at one end thereof, the first abutting block fits in the first abutting groove, the second abutting block fits in the second abutting groove, and a pull ring is installed at the other end of the limiting strip.

[0009] Preferably, positioning rods are connected to the four corners of the top of the lower mold, and positioning holes are opened at the four corners of the upper mold, and the four positioning rods are slidably fitted in the positioning holes.

[0010] Preferably, a toy body is arranged between the lower mold and the upper mold.

[0011] Preferably, a glue injection hole is provided on the upper mold.

[0012] Preferably, the outer ring of the mounting plate is provided with a sealing ring, and the sealing ring is in contact with the liquid injection port.

[0013] Preferably, the first abutment groove is located on one side of the second abutment groove, and the edge of the second abutment groove is located in the middle of the limiting strip.

[0014] The utility model has the following beneficial effects:

[0015] 1. With the cooperation of the mounting plate and the sealing ring, cooling water can be injected into the lower mold from the injection port to cool and mold the toy body. At this time, the cooling water can be filtered through the filter holes of the mounting plate to prevent impurities from entering, thereby increasing the service life of the injection mold and ensuring the cleanliness of the cooling water inside the injection mold. This can prevent impurities from entering the injection molded product and reducing product quality, and improve the stability of the injection molding process. At the same time, after the mounting plate is installed, the sealing ring can increase the sealing performance;

[0016] 2. With the cooperation of the limit strip and the second stop block, when the mounting plate needs to be replaced, the pull ring is rotated in the opposite direction to move the second stop groove at one end of the limit strip out of the second stop block, and the first stop block is completely connected to the first stop groove. At this time, the pull ring can be pulled outward to drive the mounting plate to be moved out of the injection port for cleaning and replacement. The operation is simple and convenient to use, and there is no need to disassemble the entire mold, which saves time and labor costs, thereby increasing the practicality of the device.
