Abstract
Description
A plastic molding die Technical Field
[0001] This utility model belongs to the field of mold technology, and in particular to a plastic molding mold. Background Technology
[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, molds are tools used to make shaped articles. Injection molds are devices that use one or more cavities formed by assembly, and the injection molding device uses pressure to shape the plastic into the desired shape of the product.
[0003] Current plastic molding dies rely on external force for pulling, which makes it easy to damage the molded plastic parts during demolding, reducing the yield rate of plastic parts and hindering better demolding operations.
[0004] Therefore, in view of this situation, there is an urgent need to design and produce a plastic molding die to meet the needs of practical use. Summary of the Invention
[0005] The purpose of this utility model is to provide a plastic molding die to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic molding die, comprising a lower mold housing for plastic molding, a second water supply pipe connected to the side of the lower mold housing, a pump connected to the end of the second water supply pipe away from the lower mold housing, a cooling box fixedly connected to the fixed end of the pump, a cooling pipe connected to the side of the second water supply pipe, a second telescopic rod fixedly connected inside the lower mold housing, a limit plate fixedly connected to the extended end of the second telescopic rod, and a first water supply pipe connected to the end of the cooling pipe away from the lower mold housing.
[0007] Preferably, the side of the first water supply pipe is connected to an electric valve that is fixed to the cooling box, and the side of the cooling box is equipped with a water inlet.
[0008] Preferably, a base is fixedly connected to the lower side of the lower mold housing, a first telescopic rod is fixedly connected to the upper side of the base, and a locking block is fixedly connected to the upper side of the lower mold housing.
[0009] Preferably, a movable plate is fixedly connected to the extended end of the first telescopic rod, a conveying frame is fixedly connected to the upper side of the movable plate, and a support rod is fixedly connected to the upper side of the conveying frame.
[0010] Preferably, a support plate is fixedly connected to the end of the support rod away from the conveying frame, and a first motor is installed on the upper side of the support plate.
[0011] Preferably, the output end of the first motor is fixedly connected to a threaded shaft, and a movable block that is slidably connected to the conveying frame is screwed to the side of the threaded shaft.
[0012] Preferably, the side of the conveying frame is provided with an injection port, the lower side of the moving plate is fixedly connected to an upper mold housing, and the side of the upper mold housing is provided with a fixing groove.
[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:
[0014] The plastic molding die uses a pump and a second water pipe to transport water to the cooling pipe. At the same time, the second telescopic rod is activated to move the limiting plate, transporting water to the lower mold shell for demolding of the lower mold shell and the finished plastic product. Simultaneously, the upper mold shell and the finished plastic product are demolded using the same principle. During demolding, the first motor is activated to rotate the threaded shaft, which moves the moving block to seal the injection port, facilitating the demolding of the upper mold shell.

[0025] To address the problem that relying on external force for demolding easily damages the molded plastic parts during demolding, reducing the yield rate and hindering proper demolding, a plastic molding die is provided as shown in Figures 1 to 4. This die includes a lower mold housing 12 for plastic molding. A second water supply pipe 15 is connected to the side of the lower mold housing 12.

The end of the cooling pipe 21 away from the lower mold housing 12 is connected to a first water supply pipe 14. The first motor 7 drives the threaded shaft 10 to rotate. The rotation of the threaded shaft 10 drives the moving block 8 to move. The moving block 8 blocks the injection port 9.

Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
[0029] Working principle
[0030] During use, the plastic molding die is operated by a first motor 7 driving a threaded shaft 10 to rotate. The rotation of the threaded shaft 10 drives a moving block 8 to move, which in turn seals the injection port 9.
