Two overlapping grooves 6 are opened on the inner wall of the fixed mold base 5, and sliding holes 7 are opened at the bottom of the inner walls of the overlapping grooves 6. Multiple support rods 10 are fixedly connected to the top of the mounting base 3. A first spring 13 is sleeved on the outer wall of each support rod 10, and a limit ring 14 is fixedly connected to the outer wall of each support rod 10. The fixed mold base 5 is mounted above the mounting base 3. The ends of the support rods 10 pass through the connecting plates 11 and are slidably connected to them. Two stops 12 are fixedly connected to the top of each connecting plate 11. Sliding rods 15 are installed on the outside of each connecting plate 11, and the sliding rods 15 are slidably connected to the inner wall of the sliding holes 7. A sealing block 16 is fixedly connected to the top of each sliding rod 15, and the sealing block 16 is slidably connected to the inner wall of the overlapping grooves 6. One end of the first spring 13 is fixedly connected to the limit ring 14, and the other end of the first spring 13 is fixedly connected to the connecting plate 11.

[0024] The stretching and rebound of the first spring 13 buffers the contact between the moving mold base 1 and the fixed mold base 5, reducing the impact and vibration of the mold during the mold closing process, protecting the structure and precision of the mold, and extending the service life of the mold.

[0025] The slide bar 15 drives the sealing block 16 to move into the overlapping groove 6, ensuring that the mold groove at the top of the fixed mold base 5 forms a complete groove, thus guaranteeing the shape and dimensional accuracy of the product.

[0026] After the product is formed, the moving mold base 1 moves upward. Under the elastic force of the first spring 13 and the second spring 18, the connecting plate 11 and the slide rod 15 move accordingly. The sealing block 16 presses the product upward, achieving rapid demolding.

[0029] As shown in Figure 1 The stop block 12 is located below the extrusion block 2, and the stop block 12 is extruded when it moves downward.

[0030] As shown in Figure 4 The slide rod 15 penetrates through the connecting plate 11 and is in sliding connection with the connecting plate 11, the outer wall of the slide rod 15 is fixedly connected with a limiting rod 17, the limiting rod 17 is located above the connecting plate 11, the bottom of the slide rod 15 is fixedly connected with an end block 19, the outer wall of the slide rod 15 is sleeved with a second spring 18, one end of the second spring 18 is fixedly connected with the connecting plate 11, and the other end of the second spring 18 is fixedly connected with the end block 19.

[0031] The elastic force of the second spring 18 also buffers the contact between the sealing block 16 and the fixed mold seat 5, further reducing the wear and deformation of the mold during operation.

[0034] Working principle: when the movable mold seat 1 moves downward for processing, the extrusion block 2 extrudes the stop block 12, the stop block 12 pushes the connecting plate 11 to slide downward along the support rod 10, at this time the first spring 13 is stretched, and under the elastic force of the first spring 13, the contact between the movable mold seat 1 and the fixed mold seat 5 can be buffered, at the same time the connecting plate 11 extrudes the second spring 18, under the elastic force of the second spring 18, the slide rod 15 slides downward along the inner wall of the slide hole 7, the slide rod 15 drives the sealing block 16 to move into the coincident groove 6, so that the mold groove at the top of the fixed mold seat 5 forms a complete groove, which is convenient for product molding;

[0035] After the sealing block 16 moves into the coincident groove 6, the connecting plate 11 is extruded and can continue to move downward, and extrudes the second spring 18, which can buffer the contact between the sealing block 16 and the fixed mold seat 5 through the second spring 18;

[0036] The cooling liquid is injected into the heat dissipation hole 8 through the connecting pipe 9, so that the formed product can be cooled and quickly demolded;

[0037] After the product is formed, the movable mold base 1 moves upward, the connecting plate 11 slides upward along the supporting rod 10 under the elastic force of the first spring 13 and the second spring 18, and the connecting plate 11 extrudes the limiting rod 17 upward, the limiting rod 17 drives the sliding rod 15 to move upward, and the sliding rod 15 extrudes the product upward through the sealing block 16, so that the product is quickly demolded.
