[0002] Molding fixtures are auxiliary tools used to support, position, fix, or guide materials during the molding process. Their main function is to provide precise positioning, clamping, and support in the molding process, ensuring that the shape, size, and surface quality of the material meet the design requirements. Molding fixtures are widely used in various molding processes, such as injection molding, die casting, stamping, and extrusion molding. They are usually made of materials such as metal and plastic and have high precision and durability.
[0003] Existing technologies for processing plastic product molding sheet jigs generally require manual insertion of the sheet during plastic product molding, which is not only time-consuming and labor-intensive, but also reduces the working efficiency of the equipment.
[0004] To address these issues, we propose a sheet jig for molding plastic products. Utility Model Content
[0005] The purpose of this application is to solve the problem that in the prior art, when molding plastic products, it is necessary to manually insert the sheet, which is not only time-consuming and labor-intensive, but also has low molding accuracy. Therefore, a sheet jig for molding plastic products is proposed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-5 A sheet jig for molding plastic products includes a first connecting plate 1. Two sets of guide rods 3 are fixedly connected to the upper surface of the first connecting plate 1. A protective shell 2 is fixedly connected to the outer surface of each guide rod 3. The bottom surface of each protective shell 2 is fixedly connected to the upper surface of the first connecting plate 1. By setting the protective shell 2, the guide rods 3 can be fixed, avoiding the problem of breakage or skewing of the guide rods 3 during use, which would affect the efficiency of the sheet jig for molding plastic products.
[0023] A second connecting plate 7 is provided above the first connecting plate 1. Locking blocks 5 are fixedly connected to both sides of the second connecting plate 7, and locking frames 4 are fixedly connected to both sides of the first connecting plate 1. The outer surface of each locking block 5 is engaged with the inside of the locking frame 4. The interlocking and cooperation between the locking frame 4 and the locking blocks 5 facilitates the pre-positioning of the thin sheet to be implanted on the fixture. During the molding of the plastic part, the thin sheet is inserted into the plastic part through the fixture to form a whole, further improving the working efficiency of the device.
[0024] Two pins 8 are fixedly connected to the upper surface of the second connecting plate 7. Two fixed connecting posts 6 and two fixed rods 12 are fixedly connected to the inner wall of the second connecting plate 7. A first spring 11 is sleeved on the outer surface of each fixed connecting post 6. The ends of each first spring 11 that are far apart from each other are fixedly connected to the bottom surface of the second connecting plate 7 and the upper surface of the first connecting plate 12, respectively. Two sets of guide holes 9 are opened on the upper surface of the second connecting plate 7. The interior of each guide hole 9 is slidably connected to the outer surface of the guide rod 3. A buffer ring 17 is fixedly connected to the outer surface of each fixed rod 12. Two support frames 15 are fixedly connected to the inner wall of the second connecting plate 7. Two sliding grooves 16 are opened on the inner wall of each support frame 15. Two sliders 14 are fixedly connected to the outer surface of each buffer ring 17. The outer surface of each slider 14 is slidably connected to the interior of the sliding groove 16. The cooperation between the sliders 14 and the sliding grooves 16 facilitates the stable movement of the buffer ring 17 inside the sliding grooves 16, thereby improving the working efficiency of the device.
[0025] Each buffer ring 17 has a second spring 18 fixedly connected to its bottom surface. The bottom end of each second spring 18 is fixedly connected to the inner wall of the support frame 15. The outer surface of each fixing rod 12 is slidably connected to the inside of the support frame 15. Each first spring 11 has a fixing ring 10 fixedly connected to its outer surface. The top end of each fixing ring 10 is fixedly connected to the bottom surface of the second connecting plate 7. The fixing ring 10 can be used to reinforce the first spring 11 and prevent the first spring 11 from breaking during use, thereby affecting the working efficiency of the device.
[0026] The upper surface of the first connecting plate 1 has two locking holes 19. The outer surface of each fixing rod 12 is slidably connected to the inside of the locking hole 19. The outer surface of each support frame 15 is fixedly connected with a reinforcing ring 13. The top of each reinforcing ring 13 is fixedly connected to the bottom surface of the second connecting plate 7. The reinforcing ring 13 can be used to fix the support frame 15, so as to prevent the support frame 15 from falling off or breaking and tilting during use, thereby affecting the stability of the device.
[0027] The working principle of this utility model is as follows: During use, the operator places the thin sheet to be implanted on the fixture, i.e., on the upper surface of the second connecting plate 7. Simultaneously, the operator engages the pin 8 with the plastic fitting during molding. Then, the operator applies force to the locking frame 4. Under the action of this force, the locking frame 4 and the locking block 5 move closer together. At the same time, under the action of this force, the fixing rod 12 is fixedly connected to the inner wall of the second connecting plate 7. The fixing rod 12 is connected to the buffer ring 17 and, under the buffering action of the second spring 18, moves along the inside of the support frame 15. As the rod slides downward, the outer surface of the fixing rod 12 engages with the inside of the locking hole 19, and the guide rod 3 engages with the inside of the guide hole 9. Under the upward pressure of the second connecting plate 7, the pin 8 is more tightly fixed to the plastic part during molding. At the same time, the thin sheet on the second connecting plate 7 is better integrated with the plastic part during molding. This device improves the work efficiency of the workers. The thin sheet to be implanted is placed on the fixture in advance, and the thin sheet is inserted into the plastic part through the fixture during molding to form an integral part, avoiding the problem of manual placement in traditional devices.
