Among them, the cavity 12 is located inside the bottom mold body 11, and the molding cavity 13 includes a plurality of molding cavities, which are distributed in a matrix above the cavity 12. The molding cavity 13 and the cavity 12 are connected by a through design.

[0022] The top mold 2 is located above the bottom mold 1, and the top mold 2 and the bottom mold 1 are positioned and molded together by calibration columns located on the bottom mold 1. There are four calibration columns, which are respectively located at the four corners of the bottom of the bottom mold body 11. In order to ensure the mold closing between the top mold 2 and the bottom mold 1, calibration sockets adapted to the calibration columns are opened at the four corners of the bottom of the top mold 2.

[0023] The cavity 12 is slidably connected to the carrier plate 3, and a plurality of top molds 4 extending into the molding cavity 13 are arranged in a matrix on the top of the carrier plate 3, and a lifting assembly 5 for lifting and adjusting is installed at the bottom of the carrier plate 3. The setting of the lifting assembly 5 enables the carrier plate 3 to be lifted and adjusted in the cavity 12, so that the top mold 4 thereon can be adjusted inside the molding cavity 13.

[0024] The lifting assembly 5 includes a left-right symmetrically arranged slide rail 51, which is fixedly connected to the bottom inner wall of the cavity 12. A plurality of struts 52 are movably connected to each slide rail 51, and the top of the strut 52 is movably connected to the carrier plate 3. A bidirectional screw rod 54 located inside the cavity 12 is provided between the symmetrical slide rails 51, and a plurality of connecting plates 53 for adjusting the movement of the strut rods 52 are threadedly connected to the bidirectional screw rod 54. The four bidirectional screw rods 54 in the lifting assembly 5 drive the connecting plates 53 to move, and the connecting plates 53 synchronously realize the movement of each strut rod 52, thereby realizing the lifting and lowering adjustment of the carrier plate 3.

[0025] Each slide rail 51 is slidably connected with a plurality of sliders, and both ends of the plurality of struts 52 are connected with supports through pins. The lower support is fixedly connected to the sliders on the slide rail 51, and the upper support is fixedly connected to the bottom outer wall of the carrier plate 3.

[0026] A plurality of straight plates are sleeved on the bidirectional screw rod 54, the bottom of the straight plates are fixedly connected to the bottom inner wall of the cavity 12, and the two ends of the plurality of connecting plates 53 are respectively fixedly connected to the sliders on the two side rails 51. The connection between the connecting plates 53 and the sliders can adjust the displacement of the connecting plates 53 with the movement of the bidirectional screw rod 54, thereby ensuring the linear displacement of the slider.

[0027] The top of the carrier plate 3 is provided with a plurality of threaded columns in a matrix. The top mold 4 is composed of a telescopic member 41 and a template 42. The telescopic member 41 includes an inner grooved cylinder 411 threadedly connected to the threaded column. A partition plate 412 is fixedly connected to the inside of the inner grooved cylinder 411, and a sliding plate 413 located inside the inner grooved cylinder 411 is slidably connected above the partition plate 412. The telescopic member 41 is conveniently assembled between the inner grooved cylinder 411 and the threaded column, so that it is easy to disassemble and maintain.

Under the action of the telescopic member 41, the template 42 in the top mold 4 can realize convenient demoulding of the injection molded product through the movement of the telescopic member 41 after the mold body completes the injection molding of the product.

[0029] The working principle of the utility model is: when the product is injection molded, the lifting assembly 5 is adjusted according to the thickness of the gasket to be produced, so that the carrier plate 3 drives the top mold 4 to move, so that it can be displaced and adjusted in the molding cavity 13 of the bottom mold 1 to achieve the required depth of the gasket.

[0030] After the adjustment is completed, the top mold 2 and the bottom mold 1 are closed. After the closing is completed, the material is injected into the inside to realize the injection molding production of the product.

[0031] During the adjustment operation of the lifting assembly 5, the bidirectional screw rod 54 is rotated to drive the connecting plate 53 thereon to perform displacement adjustment. The displacement of the two 53 causes the sliders at both ends thereof to perform displacement adjustment on the corresponding slide rails 51, thereby causing the carrier plate 3 to perform lifting and lowering adjustment in the cavity 12, and causing the top mold 4 disposed on the top thereof to perform displacement adjustment in the molding cavity 13, so as to adapt to the injection molding production operation of gaskets of different thicknesses.
