In some companies, the processing of plastic washers often requires special molding equipment for molding, so a plastic one-time molding device is needed for molding and stamping, and the plastic is stamped into finished products for assembly of automobile parts.

[0003] Existing plastic parts molding equipment generally adopts direct pressure stamping. After the round cap-shaped plastic products are formed, during the material removal process, it is necessary to manually take out the product in the mold first, and then put the material to be processed into the mold again. However, this process of taking and putting makes the processing time longer and the continuity is poor, which affects the efficiency of the current processing.

[0004] Therefore, we propose a plastic parts molding equipment to solve the above problems. Summary of the invention

[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] Reference Figure 1-Figure 2 A plastic part molding device comprises a base 1, a U-shaped frame 2 is fixedly connected to the top of the base 1, a workbench 3 located above the base 1 is arranged in the U-shaped frame 2, a hydraulic expander 4 is installed on the top surface of the U-shaped frame 2, a constant pressure device is installed at the bottom of the hydraulic expander 4, connecting grooves 7 are opened on the inner walls of both sides of the U-shaped frame 2, connecting plates 5 extending into the connecting grooves 7 are arranged on both sides of the workbench 3, a driving component for driving the workbench 3 to reciprocate is arranged in the connecting groove 7, plastic molds 12 are slidably installed at both ends of the workbench 3, the plastic molds 12 slide up and down in the workbench 3, a wedge block 13 is fixedly connected to the bottom of each plastic mold 12, and a top plate 11 is arranged on both sides of the top surface of the base 1 to abut against the wedge block 13 as the workbench 3 moves. After the workbench 3 moves out of the U-shaped frame 2, the wedge block 13 at the bottom of the plastic mold 12 abuts against the top plate 11 of the base 1, and the plastic mold 12 is pushed out of the workbench 3, so that the product in the plastic mold 12 can be easily taken out. Both ends of the workbench 3 are provided with mounting grooves 16, and the mounting grooves 16 are embedded in the workbench 3. Both sides of the plastic mold 12 are symmetrically provided with reset components that extend into the mounting grooves 16 to reset the plastic mold 12. The workbench 3 is moved into the U-shaped frame 2 by the driving component. When the processing is completed, the plastic mold 12 processed by the workbench 3 is moved out of the U-shaped frame 2 by the driving component. At the same time, the plastic mold 12 on the other side is moved into the U-shaped frame 2, so that the material in the plastic mold 12 can be processed, the continuity of plastic production is improved, and the processing efficiency is improved.

[0022] Reference Figure 3 The driving assembly includes a lead screw 6 rotatably installed in a connecting groove 7 on one side and a guide rod fixedly installed in the connecting groove 7 on the other side. The connecting plates 5 on both sides of the workbench 3 are respectively installed on the lead screw 6 and slidably sleeved on the guide rod. A motor 8 connected to the lead screw 6 is installed on one side of the U-shaped frame 2. Through the rotation of the motor 8, the lead screw 6 drives the workbench 3 to move in the U-shaped frame 2.

[0023] Reference Figure 4 The reset component includes a spring 15 and a support plate 14. The support plate 14 is fixedly connected to the outer cylindrical surface of the plastic mold. The spring 15 is fixedly connected between the top wall of the mounting groove 16 and the top surface of the support plate 14. When the wedge block 13 at the bottom of the plastic mold 12 abuts against the top plate 11 of the base 1, the plastic mold 12 is pushed out of the workbench 3. At the same time, the support plate 14 in the mounting groove 16 of the plastic mold 12 squeezes the spring 15. When the product is removed, the material is placed in the plastic mold 12. As one end of the workbench 3 moves into the U-shaped frame 2, the wedge block 13 is separated from the top plate 11, and the spring 15 pushes the support plate 14 back to reset the plastic mold 12.

[0024] Reference Figure 2 A support plate 10 is fixedly connected to the bottom of the workbench 3 . When the material in the plastic mold 12 on the workbench 3 is processed, the support plate 10 improves the stability of the workbench 3 .

When the workbench 3 moves, the support plate 10 moves synchronously, and the roller 17 at the bottom of the support plate 10 improves the smoothness of movement.

[0026] Reference Figure 2 The wedge at the top of the ejector plate 11 is opposite to the wedge at the bottom of the wedge block 13. As the workbench 3 moves, the wedge block 13 below the plastic mold 12 abuts against the wedge of the ejector plate 11, so that the plastic mold 12 is ejected during the movement of the workbench 3.

[0027] Working principle:

[0028] First, the material is placed in the plastic mold 12 of the workbench 3, and then the workbench 3 is moved to the bottom of the U-shaped frame 2 by the screw 6, and the material is processed by the hydraulic telescope 4. When the processing is completed, one end of the workbench 3 is moved out of the U-shaped frame 2 by the screw 6, and in the process of moving, the wedge block 13 at the bottom of the plastic mold 12 is abutted against the top plate 11 on the base 1 to take out the product in the plastic mold 12. At the same time, the material is placed in the plastic mold 12 again, and the plastic mold 12 on the other side of the workbench 3 is processed in the U-shaped frame 2, so as to improve the continuity of the processing and improve the processing efficiency.
