Description

Technical Field

[0001] The utility model relates to the technical field of pre-deformation moulds, in particular to a pre-deformation mould for a pressure cooker liner cover. Background Art

[0002] The pre-deformation mold for the pressure cooker liner is a mold specially used to manufacture the pressure cooker liner. Its design principle is based on material forming technology and pre-deformation theory. By precisely controlling the shape, size and process parameters of the mold, the liner formed in the mold can better adapt to the working environment and pressure changes of the pressure cooker during subsequent use.

[0003] After using the mold, the residue on the mold surface should be cleaned in time to avoid affecting the next use. At the same time, the mold should be lubricated and maintained regularly to extend the service life of the mold. If the mold is found to be worn or damaged, it should be repaired or replaced in time. Each of the above operations requires the mold to be disassembled, and the existing mold is installed by using multiple screws and bolts for fixed installation. This will result in the need to operate each screw and bolt during disassembly and installation, which greatly increases the working time.

[0004] In order to solve the above problems, the present application proposes a pre-deformation mold for a pressure cooker liner cover. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a pre-deformation mold for a pressure cooker liner cover, comprising a static mold group, on which a positioning column, a connecting flange and an anti-dropping buckle are fixedly provided, on which a mold groove, a mounting groove and a fixing groove are opened, on which a movable mold group is movably provided on the side of the static mold group, on which an injection port is opened, in which a shaping mold is fixedly provided in the mold groove, on which a mounting block and an extrusion tube are fixedly provided, on which a through hole is opened, in which an elastic metal sheet is movably provided, on which an elastic sleeve is movably provided at the bottom of the extrusion tube, on which a spring is fixedly provided at the bottom, on which a fixing sleeve is fixedly provided at the other end of the spring, and on which a connecting rod is provided at the side of the fixing sleeve.

[0006] Preferably, support columns are fixedly provided at the bottom of the static die set and the dynamic die set, a positioning groove is opened on the side of the dynamic die set, and the positioning column is movably connected in the positioning groove.

[0007] Preferably, the mounting blocks are arranged circumferentially on the side of the shaping mold, the mounting blocks are movably connected in the mounting groove, and the fixing groove is provided in the mounting groove.

[0008] Preferably, the extrusion tube is fixedly connected to the back of the shaping die, the outer ring diameter of the extrusion tube is equal to the diameter of the fixing groove, and the extrusion tube is movably connected in the fixing groove.

[0009] Preferably, the fixing sleeve is fixedly connected to the inner wall of the fixing groove, one end of the spring is fixedly connected to the fixing sleeve, the other end of the spring is fixedly connected to the elastic sleeve, and the elastic sleeve is slidably connected in the fixing groove.

[0010] Preferably, the elastic sleeve and the fixed sleeve are both annular in shape, the outer ring diameter of the fixed sleeve is equal to the outer ring diameter of the elastic sleeve, and the inner ring diameter of the elastic sleeve is greater than the inner ring diameter of the fixed sleeve.

[0011] Preferably, the connecting rod is fixedly connected in the fixing groove, the elastic metal sheet is fixedly connected to the connecting rod, the outer side surface of the elastic metal sheet and the inner side surface of the elastic sleeve are slidably connected, the top shape of the elastic metal sheet is fan-shaped, and the fan-shaped diameter of the elastic metal sheet is smaller than the diameter of the through hole when the elastic metal sheet is contracted.

[0012] The above technical solution of the utility model has the following beneficial technical effects:

[0013] The utility model provides four circumferentially arranged mounting blocks on the mold. When the mounting block enters the mounting groove on the static mold assembly, the extrusion tube on the back of the mounting block will push the elastic sleeve into the fixed groove. As the elastic sleeve moves inward, the top of the elastic metal sheet will gradually expand in diameter and then expand on the outside of the through hole of the mounting block, thereby fixing the mounting block in the mounting groove. The installation operation is simple and fast. When disassembly is required, it is only necessary to squeeze the elastic metal sheet inward with a tool, and then the spring on the fixed sleeve will pop out the elastic sleeve outward, thereby reducing the diameter of the top of the metal sheet, and then the mounting block pops out of the mounting groove, and finally the disassembly of the mold is completed, reducing the operation time of the screws and bolts, making the installation and disassembly of the mold simpler and more convenient, and providing convenience for the staff to inspect, clean, maintain and replace the mold.
