Description

Technical Field

[0001] The present application relates to the field of resin molding technology, and in particular to a demoulding mechanism for a high-pressure resin molding die. Background Art

[0002] High-pressure resin molding is a molding process widely used to manufacture high-performance composite materials and components. This process typically involves injecting resin and reinforcement into a mold under high pressure, followed by heating or reaction curing to form the product. However, due to the strong adhesion between the cured resin and the mold, the resin undergoes a curing reaction under high pressure and temperature conditions, forming a tight bond with the mold. Therefore, a demolding mechanism is required for demolding.

[0003] In related technologies, a mechanical demolding mechanism pushes and lifts the solidified product through a push rod, bracket or other structure to separate the resin product from the mold; however, due to the characteristics of the mechanical structure, the adhesion between the product and the mold is easily damaged during the demolding process, thereby affecting the overall quality of the product.

[0004] Therefore, those skilled in the art provide a demoulding mechanism for a high-pressure resin molding die to solve the problems raised in the above background technology. Utility Model Content

[0032] The lower die base 1 has an upper die plate 2 mounted on the top of the lower die base 1.

A bidirectional screw 32 is rotatably mounted on one side of the inner wall of the mounting frame 31, and a movable seat 33 threadedly connected on both sides thereof. A lifting plate 34 is slidably mounted inside the lower mold base 1, and a scissor rod 35 is hinged between the lifting plate 34 and the movable seat 33 through a rotating shaft. A driving component 36 is provided on one side of the mounting frame 31 for driving the lifting plate 34 to move; a pneumatic component 37 is provided between the mounting frame 31 and the lifting plate 34 for demoulding the molded resin;

[0034] One end of the bidirectional screw 32 passes through the mounting frame 31 and extends to the outside of the mounting frame 31. A driven bevel gear 361 is fixedly mounted on the end of the bidirectional screw 32 located outside the mounting frame 31. A servo motor 362 is mounted at the bottom of the inner cavity of the lower die base 1. A driving bevel gear 363 is fixedly mounted on the output end of the servo motor 362. The driving bevel gear 363 and the driven bevel gear 361 are meshedly connected.

[0035] In this embodiment, the servo motor 362 drives the active bevel gear 363 to rotate, and utilizes the meshing connection between the active bevel gear 363 and the driven bevel gear 361 to drive the bidirectional screw 32 to rotate. At the same time, the threaded connection between the bidirectional screw 32 and the movable seat 33 is utilized to make the two movable seats 33 move synchronously, and utilizes the scissor characteristics of the scissor rod 35 to lift and demold the lifting plate 34 and the product on top of it.

[0036] Please continue to refer to Figure 4 A crossbar 38 is fixedly mounted on the other side of the inner wall of the mounting frame 31, and one end of the crossbar 38 passes through the movable seat 33 and is slidably connected thereto;

[0037] In this embodiment, the stability of the movable base 33 can be maintained when it moves, thereby preventing the movable base 33 from shaking and affecting the demoulding.

[0038] Reference Figure 4 as well as Figure 5 The pneumatic assembly 37 includes a fixed seat 371 fixedly installed inside the mounting frame 31, an airbag 372 is installed between the fixed seat 371 and the movable seat 33, a cylinder 373 is installed around the bottom of the jacking plate 34, a top plate 374 is provided around the top of the jacking plate 34, and a sliding rod 375 fixedly installed at its bottom, the bottom end of the sliding rod 375 sequentially passes through the jacking plate 34 and the cylinder 373 and extends to the interior of the cylinder 373, the sliding rod 375 is located inside the cylinder 373 and is installed with a return spring 376, the bottom end of the return spring 376 is fixedly connected to the bottom of the inner cavity of the cylinder 373, a number of air holes 377 are opened between the cylinder 373 and the jacking plate 34, the top of the airbag 372 is connected to a hose 378, and a connecting pipe 379 is installed between the hose 378 and the cylinder 373;

[0039] In this embodiment, while the movable seat 33 is moving, it squeezes the airbag 372, and the gas inside the airbag 372 is injected into the interior of the cylinder 373 through the hose 378 and the connecting pipe 379. As the gas is continuously discharged, the gas pushes up the top plate 374 through the air hole 377, so that the gas inflates the gap between the product and the lower mold base 1 through the gap between the top plate 374 and the countersunk hole, thereby separating the bond between the product and the lower mold base 1 and maintaining the overall quality of the product during demolding.

[0040] One side of the air bag 372 is connected to a one-way air intake valve so that the top plate 374 can take in air when it contacts the countersunk hole.

[0041] Please continue to refer to Figure 5 Countersunk holes are provided around the top of the jacking plate 34, and the top plate 374 is slidably installed inside the countersunk holes; the overall flatness of the jacking plate 34 can be maintained to avoid any impact during resin molding.

[0043] In this embodiment, the scissor rods 35 are used to lift the lifting plate 34 and sufficient movement space is provided for the scissor rods 35 .

[0044] The working principle of the demoulding mechanism for a high-pressure resin molding die according to the embodiment of the present application is as follows: when the product inside the lower mold base 1 is demoulded, the servo motor 362 drives the driving bevel gear 363 to rotate, and the meshing connection between the driving bevel gear 363 and the driven bevel gear 361 drives the bidirectional screw 32 to rotate. At the same time, the threaded connection between the bidirectional screw 32 and the movable base 33 is used to make the two movable bases 33 move synchronously, and the scissor-fork characteristics of the scissor rods 35 are used to lift and demould the lifting plate 34 and the product on top of it;

[0045] While the movable seat 33 is moving, it squeezes the airbag 372 and injects the gas inside it into the interior of the cylinder 373 through the hose 378 and the connecting pipe 379. As the gas is continuously output, the gas lifts the top plate 374 through the air hole 377, so that the gas inflates the gap between the product and the lower mold base 1 through the gap between the top plate 374 and the countersunk hole, separates the bonding between the product and the lower mold base 1, and maintains the overall quality of the product when demolding.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
