Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing, and specifically, to a molding device for rubber processing. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a very small external force, and can return to its original state after the external force is removed. When forming rubber products, generally, molten rubber is injected into a mold.

[0003] After retrieval, the utility model patent with the publication number of CN212171143U discloses a new type of molding device for rubber processing, including a bottom plate. The rear side of the top of the bottom plate is fixedly connected with a fixed frame. The top of the front of the fixed frame is fixedly connected with a fixed plate. A hydraulic cylinder is fixedly connected inside the fixed plate. The piston end of the hydraulic cylinder is fixedly connected with an upper mold. The top of the bottom plate is fixedly connected with a lower mold located below the upper mold. The left side of the top of the bottom plate is fixedly connected with a cylinder; through the settings of the bottom plate, fixed frame, fixed plate, hydraulic cylinder, upper mold, lower mold, cylinder, connecting plate, fixed rod and air jet cleaning component, the problem that the existing molding device does not have the function of cleaning the inner cavity of the mold, resulting in the problem that the residue of the mold corner material will affect the subsequent injection-molded products once remaining in the mold is solved. This new type of molding device for rubber processing has the advantage of automatically cleaning the inner cavity of the mold and improves the mold cleaning efficiency.

[0004] However, the above patent still has the following deficiencies: after the upper mold and the lower mold are extruded and formed, it is necessary to manually remove the formed material in the lower mold, and the convenience is poor; in addition, during the process of the cylinder driving the brush to move, the brush will push the residue of the mold corner material on the lower mold to the rear side of the bottom plate, which is not convenient for the residue to fall into the material leakage hole and affects the quality of residue cleaning. Therefore, we propose a molding device for rubber processing. Summary of the Utility Model
