DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a positioning structure of a high-precision mold includes a guide plate 6, a shock absorber 7, a pressure block 8, a positioning sleeve 9, a slide plate 10, and a pressure pad 11. The guide plate 6 and the slide plate 10 are both slidably sleeved with the positioning sleeve 9, the pressure pad 11 is fixedly connected to one end of the slide plate 10, the lower end of the shock absorber 7 is fixedly connected to the pressure block 8, the upper ends of the guide plate 6 and the shock absorber 7 are fixedly connected to the pressure plate 3, the lower end of the positioning sleeve 9 is fixedly connected to the support plate 4, the lower end surface of the pressure plate 3 is fixedly connected to the upper mold 1, the upper end of the support plate 4 is provided with a lower mold 2, and the pressure pad 11 is pressed on the outer wall of the lower mold 2.

[0024] In this embodiment, a plurality of pulleys 14 are rotatably disposed in the positioning sleeve 9 , and the skateboard 10 is disposed between the plurality of pulleys 14 . The pulleys 14 can reduce the friction force when the skateboard 10 moves, thereby reducing the loss of the skateboard 10 .

[0025] In this embodiment, the contact surfaces of the pressure block 8 and the slide plate 10 are both made of an inclined structure, and two slide rods 12 are slidably sleeved on the positioning sleeve 9. One end of the two slide rods 12 is fixedly connected to the pressure pad 11. A spring 13 is arranged between the pressure pad 11 and the positioning sleeve 9. The spring 13 is movably sleeved on the outer wall of the slide rod 12. The spring 13 is used to prevent the pressure pad 11 from having a large displacement with the positioning sleeve 9 under a natural force state, and to prevent the lower end of the pressure block 8 from facing the upper end of the plane of the slide plate 10, resulting in the problem of being unable to press down.

[0026] In this embodiment, a square groove 15 is provided at the upper end of the support plate 4, and shock absorber 2 16 is fixedly connected to the inner walls of the four sides of the square groove 15. A mounting seat 17 is provided between the four shock absorbers 2 16. A mounting groove 18 is provided at the upper end of the mounting seat 17. A mounting block 19 is fixedly connected to the lower end surface of the lower mold 2. The mounting block 19 is slidably sleeved in the mounting groove 18, which makes it convenient to remove the lower mold 2 during demolding and reduces the difficulty of demolding.

[0027] In this embodiment, the mounting seat 17 is movably arranged in the square groove 15, and one end of four shock absorbers 16 are pressed against the surface of the mounting seat 17. The shock absorbers 16 are used to reduce the vibration of the mounting seat 17 in the horizontal direction, thereby improving the stability of the lower mold 2 installed at its upper end.

[0028] In this embodiment, a bracket 5 is fixedly provided on the outer wall of the support plate 4, a hydraulic cylinder 20 is fixedly sleeved on the upper end of the bracket 5, and the lower end of the hydraulic cylinder 20 is fixedly connected to the pressing plate 3, and the pressing plate 3 is driven by the hydraulic cylinder 20 to drive the upper mold 1 to move.

[0029] In this embodiment, the pressure plate 3 is slidably arranged in the bracket 5, and guide rods 21 are fixedly connected to both sides of the upper end surface of the pressure plate 3. The two guide rods 21 are slidably sleeved on the top plate of the bracket 5. The guide rods 21 guide the lifting and lowering movement of the pressure plate 3 to improve stability.

[0030] It should be noted that the utility model is a positioning structure for a high-precision mold. When in use, the lower mold 2 can be installed on the mounting seat 17 by means of the mounting block 19 sleeved in the mounting groove 18. When the hydraulic cylinder 20 drives the pressure plate 3 to move downward, and then drives the upper mold 1 to move toward the lower mold 2 for mold closing, the position of the upper mold 1 is positioned by means of the guide plate 6 sleeved in the positioning sleeve 9. At the same time, the shock absorber 7 drives the pressure block 8 to move downward, and finally presses the slide plate 10 to slide, and the four sides of the lower mold 2 are pressed and positioned by the pressure pad 11, thereby improving the accuracy of the upper mold 1 and the lower mold 2 when the mold is closed.
