Description

Technical Field

[0001] This invention belongs to the field of injection molding machine technology, specifically relating to a device for stably clamping injection molds in an injection molding machine. Background Technology

[0002] Molds are widely used in blanking, extrusion, powder metallurgy pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber and other products. Molds generally consist of two parts: a moving mold and a fixed mold. The two parts can be separated or combined. The locking pins of the moving mold engage with the locking pin slots of the fixed mold, so that the moving mold and the fixed mold are in contact, thereby forming an injection cavity.

[0003] When using a mold, it needs to be clamped with a clamping device before the mold opening process can be carried out. Currently, when using a moving mold, a clamping device is needed to fix the moving mold to the power source. Although this achieves the purpose of fixing, the clamping device is relatively troublesome when fixing the moving mold, making it inconvenient to change the mold later. Summary of the Invention

[0004] The purpose of this invention is to provide a device for stably clamping injection molds in an injection molding machine, which facilitates mold replacement and improves mold replacement efficiency.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A device for stably clamping an injection mold in an injection molding machine is provided, comprising a base plate, a lower mold base and a clamping device being provided at the upper end of the base plate, the clamping device being located on both sides of the lower mold base, an upper mold base being provided at the upper end of the lower mold base, a sliding groove being provided on the upper surface of the upper mold base, a movable frame being slidably connected inside the sliding groove, and a clamping plate being slidably connected inside the movable frame; a support column and a hydraulic telescopic rod are fixedly connected at the upper end of the base plate, the extended end of the hydraulic telescopic rod being fixedly connected to the clamping plate; a mounting plate is fixedly connected at the upper end of the support column, and the injection molding machine body is mounted on the upper end of the mounting plate.
