Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to an automatic ejection mold. Background Art

[0002] The mold is a process equipment used in the production of industrial products. It is mainly suitable for manufacturing and processing industries. It is used as a forming tool in conjunction with stamping, forging, and casting forming machinery, as well as forming machinery used for forming and processing non-metallic materials such as plastics, rubber, and ceramics.

[0003] Existing molds often do not have ejection devices to simplify the structure and reduce costs.

[0004] However, the existing injection molds usually need to be manually removed from the mold cavity after the cooling and molding is completed, which can easily damage the edge shape of the plastic product. At the same time, the product is easy to stick to the inner wall of the mold cavity and is not conducive to removal. Therefore, we propose an automatic ejection mold. Utility Model Content

[0010] Furthermore, the lifting mechanism includes an upper fixed block, a hydraulic rod, a hydraulic cylinder and a lower fixed block. The upper fixed blocks are fixedly provided on the left and right sides of the upper mold frame, and the lower fixed blocks are fixedly provided on the left and right sides of the lower mold frame. The upper side of the lower fixed block is fixedly connected to a hydraulic cylinder, and the upper side of the hydraulic cylinder is fixedly connected to a hydraulic rod. The upper side of the hydraulic rod is fixedly connected to the upper fixed block. The hydraulic cylinder is used to enable the hydraulic rod to be extended and retracted up and down, and the hydraulic rod drives the upper fixed block to move up and down, thereby driving the mold to automatically open or close.

[0011] Furthermore, four evenly distributed positioning guide pillars are fixedly provided on the upper surface of the lower mold frame, and four evenly distributed positioning guide sleeves are provided inside the upper mold plate and the upper mold frame.
