There are two cylinders on the bottom plate, and a power supply box is provided on the bottom plate. The bottom of the base is connected to the end of the piston rod in the cylinder, and a lower mold is provided on the base. The top seat is located directly above the base, and an upper mold is provided at the bottom of the top seat. The upper mold is located directly above the lower mold and matches the lower mold. An installation groove is provided in the base, and an electric heating wire is provided in the installation groove. The electric heating wire is electrically connected to the power supply box. Injection holes are provided in both the top seat and the upper mold. A driving rod is provided at the top of the top seat. In this utility model, the electric heating wire heats the lower mold, so that the injection liquid on the lower mold maintains an appropriate temperature and does not coagulate, ensuring the injection quality of the mold product.

[0004] When the existing heating plate is connected to the injection mold to be heated, it needs to be installed and connected through bolts and tools. The steps of this installation and connection are relatively complex, which in turn leads to a decrease in the operation efficiency and affects the use effect. In view of the above problems, a heating plate for an injection and extrusion mold is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide a heating plate for an injection and extrusion mold to solve the problem in the above background art that when the heating plate is connected to the injection mold to be heated during operation, it needs to be installed and connected through bolts and tools.

The heating mechanism includes a reinforcement frame body. A heating plate is provided inside the reinforcement frame body. An electric heating block is provided at the bottom of the heating plate, and a heat conduction base layer is provided at the bottom of the heating plate. By connecting a plurality of electric heating blocks distributed on the heating plate to a power supply, electric heating work is realized through electricity. At the same time, the heat generated by the electric heating block is carried out by using the heat conduction base layer, thereby facilitating the provision of an effective heating function.

[0007] The clamping mechanism includes a mounting plate. The clamping cylinders are symmetrically installed through the side surface of the mounting plate. The output end of the clamping cylinder is fixedly connected to a connecting plate. One side of the connecting plate is fixedly connected to a lifting cylinder.
