Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a novel rubber seal molding die. Background Technology

[0002] Rubber seals are components made of rubber material used to seal and prevent the leakage of liquids, gases, or solid substances. Rubber seals can be manufactured using molding dies, precisely shaping the rubber material under high temperature and pressure to ensure that the seal's dimensions, shape, and performance meet requirements.

[0003] However, existing molding dies have shortcomings in the production of rubber seals. First, existing molding dies require rubber material to be placed into the mold cavity before hot pressing, but the limited space between the upper and lower molds makes the material feeding operation inconvenient. Second, when hot pressing rubber seals, the surface temperature of the seals is high, and there is a lack of a rapid heat dissipation structure, which can easily cause burns when handling them. Therefore, a new type of rubber seal molding die is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a novel rubber seal molding die, which aims to improve the existing molding die. Before hot pressing, the rubber material needs to be put into the mold cavity. However, due to the limited space between the upper and lower molds, the feeding operation is inconvenient. In addition, the existing molding die lacks a rapid heat dissipation structure for the seal when hot pressing rubber seals, which can easily cause burns when handling the seal.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel rubber sealing component molding die, comprising a base plate, a top frame fixedly connected to one end of the top of the base plate, a cylinder two fixedly installed in the middle of the top of the top of the top frame, an upper mold fixedly connected to the output end of the cylinder two, sliding components installed on both sides of the top of the base plate, a lower mold connected to the top of the sliding components, locking components installed at the bottom of both sides of the inner wall of the top frame, a cavity provided at the bottom of the inner wall of the lower mold, cylinder one fixedly installed on both sides of the bottom end of the lower mold, a connecting plate fixedly connected to the output ends of two cylinders one through the inner wall of the cavity, a plurality of ejector rings fixedly connected to the top of the connecting plate, and an annular opening provided at the top of the inner wall of the cavity corresponding to the plurality of ejector rings, and a heat dissipation component installed on the top of the lower mold;

[0006] The locking assembly includes an electromagnet and an iron plate. The electromagnet is fixedly installed at the bottom of one side of the inner wall of the top frame, and the iron plate is fixedly connected to one side of the lower mold.

[0007] As a further description of the above technical solution:

[0008] The heat dissipation assembly includes a fan, a frame tube, and several air outlets. The frame tube is fixedly connected to the top of the lower mold, and several air outlets are opened on the surface of the frame tube. The fan is fixedly installed on the back of the lower mold, and the output end of the fan is fixedly connected to the frame tube.

[0009] As a further description of the above technical solution:

[0010] The top material ring is inserted into the inner wall of the annular opening.

[0011] As a further description of the above technical solution:

[0012] The sliding assembly includes two slide rails and two sliding feet. The two slide rails are fixedly connected to the two sides of the top of the base plate, and the inner walls of the two slide rails are slidably connected to the sliding feet.

After the cylinders 5 are started, they can push the connecting plate 6 and the multiple ejector rings 7 upward to perform ejection operation, increasing the exposed area. An annular opening 8 is provided at the top of the inner wall of the cavity 4 corresponding to the multiple ejector rings 7, providing space for the ejector rings 7 to pass through. A heat dissipation component is installed on the top of the lower mold 2 to dissipate heat and cool the molded rubber seals, avoiding burns when handling due to excessive surface temperature.

[0032] Reference Figure 1 The locking assembly includes an electromagnet 19 and an iron plate 20. The electromagnet 19 is fixedly installed on the bottom of one side of the inner wall of the top frame 16, and the iron plate 20 is fixedly connected to one side of the lower mold 2. When the electromagnet 19 is energized, it will generate electromagnetic field and attract the iron plate 20.

[0033] Reference Figure 2 The heat dissipation component includes a fan 11, a frame tube 12, and several air outlets 13. The frame tube 12 is fixedly connected to the top of the lower mold 2. Several air outlets 13 are opened on the surface of the frame tube 12 to make the air outlet more uniform and to blow the air to the surface of the workpiece from multiple directions, thereby accelerating the cooling speed. The fan 11 is fixedly installed on the back of the lower mold 2, and the output end of the fan 11 is fixedly connected to the frame tube 12. After the fan 11 is started, it can introduce the air behind the molding die and deliver it into the frame tube 12.

[0034] Reference Figure 3 The ejector ring 7 is inserted into the inner wall of the annular opening 8. The ejector ring 7 can pass through the annular opening 8 to eject the workpiece in the lower mold cavity 2, so as to facilitate heat dissipation and material removal.

[0035] Reference Figure 1The sliding assembly includes two slide rails 17 and two sliding feet 18. The two slide rails 17 are fixedly connected to the two sides of the top of the base plate 1, and the inner walls of the two slide rails 17 are slidably connected to the sliding feet 18. The two sliding feet 18 are fixedly connected to the two ends of the bottom of the lower mold 2. By using the sliding feet 18, the lower mold 2 can slide on the slide rails 17. When picking up or putting down materials, the lower mold 2 is pulled out. When hot pressing, the lower mold 2 is pushed to the farthest end.

[0036] Reference Figure 3 A heating wire 9 is fixedly connected to the top of the inner wall of the lower mold 2. The heating wire 9 can heat the rubber material and work with the upper mold 3 to form the seal.

[0040] Working principle: The lower mold 2 of this molding die can be pushed and pulled along by the slide rail 17 and slide foot 18. When feeding rubber raw materials and picking up finished products, the lower mold 2 can be pulled out to increase the operating space and avoid inconvenience in material handling due to the close proximity to the upper mold 3. When the lower mold 2 is pushed to the farthest point, the electromagnet 19 can attract the iron plate 20 on the lower mold 2 to keep the lower mold 2 stable during the hot pressing process. The upper mold 3 is moved down by the cylinder 10 until it is close to the lower mold 2. After the bonding is completed and the mold is closed, the rubber material is heated by the heating wire 9. Under the action of hot pressure, the seal is formed. After completion, the upper mold 3 is raised. After the rubber seal is hot-pressed, the cylinder 5 is activated to push the connecting plate 6 and multiple ejector rings 7 upward, which can lift the workpiece in the mold cavity to increase the exposed area. Then, the fan 11 is activated to introduce air, which is blown from multiple directions to the surface of the workpiece through several air outlets 13 on the frame tube 12, so that it can quickly dissipate heat and cool down, preventing burns when handling.
