[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material.

[0003] Patent number: CN219294575U is a Chinese patent, a mold for convenient demoulding, including a base, a bracket is fixedly installed on the upper side of the base, a first top plate is fixedly installed on the upper end of the bracket, a fixed shell is fixedly installed on the lower side of the first top plate, a motor is fixedly installed on the upper side of the first top plate, a threaded rod is fixedly installed on the output end of the motor, and a connecting plate is threadedly connected to the outer side of the threaded rod. The utility model drives the threaded rod to rotate through the motor, and the threaded rod drives the connecting plate connected to its outer thread to move downward, and the connecting plate drives the slide plate, the support plate and the upper die seat to move downward, and the upper die seat is clamped into the lower die seat. At this time, the ejector pin is clamped into the positioning groove, and when the ejector pin contacts the second top plate, it drives the second top plate to move downward, and the second top plate compresses the spring through the connecting rod and the slider, and at the same time, the second top plate drives the ejector block to move downward, and when the upper die seat and the lower die seat are completely closed, the upper side of the ejector block is just flush with the bottom of the lower die seat, so as to avoid the ejector block from affecting the injection molding.

[0004] The above-mentioned shortcomings exist as follows: the applicant believes that after the casting is processed through heat treatment, the inner wall of the mold is adsorbed to the lower mold, and the surface temperature of the mold is high and cannot be quickly taken out, thus affecting work efficiency. As the overall operation time of the device is too long, the upper side wall of the workbench will absorb more dust. If it is not handled in time, the dust will also be adsorbed on the outer side walls of the bottom mold and the lower mold, thus affecting the molding quality of the casting. Therefore, technical personnel in this field provide a mold that is easy to demold to solve the above-mentioned problems.

[0005] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility Model Content

[0030] Specifically, a hydraulic device 3 is installed in the middle position of the upper side wall of the L-shaped mounting seat 2, and a protective cover 4 is installed in the middle position of the lower side wall of the L-shaped mounting seat 2. The output end of the hydraulic device 3 passes through and is slidably connected to the middle position of the lower side wall of the protective cover 4. The output end of the hydraulic device 3 is connected to the upper mold 15, and the upper mold 15 is matched with the lower mold 19. The output end of the hydraulic device 3 is controlled by the control box 7 to drive the upper mold 15 to move toward the lower end until the casting is fitted with the lower mold 19 and the outer wall of the bottom mold 21, and then hot pressing is performed.

The above structure is simple, relying on the servo electric cylinder 27 as the transmission basis to drive the demoulding structure to demould, and the transmission method is simple As the overall operation time of the device is too long, the upper side wall of the workbench 2 will absorb more dust. If it is not handled in time, the dust will also be absorbed on the outer side walls of the bottom mold 21 and the lower mold 19, thereby affecting the molding quality of the casting. At this time, the two output ends of the dual-axis motor 31 are controlled by the control box 7 to drive the first screw rod 14 and the second screw rod 17 to rotate respectively, thereby driving the two movable blocks 6 to move to one side and the other side respectively. The threads of the first screw rod 14 and the second screw rod 17 are distributed as positive threads and negative threads. Through the two movable blocks 6, the two mounting plates 13 are driven to move in opposite directions respectively, thereby driving the two cleaning scrapers 12 respectively, and the dust on the workbench 2 is collected in the dust cleaning box 9 through the two groups of cleaning holes 11. Pulling the handle 8 makes the dust cleaning box 9 stretch to the front side, so as to facilitate the subsequent unified cleaning.
