Description

Technical Field

[0001] This utility model relates to the field of hot press molding machine technology, specifically a hot press molding machine for rubber products. Background Technology

[0002] A thermoforming machine is a widely used piece of equipment in industrial production, primarily used to shape rubber materials into desired shapes using high temperature and high pressure. Its working principle utilizes thermoforming technology, where heating and applying pressure cause the rubber material to undergo plastic deformation within a mold, thereby obtaining rubber products of specific shapes and sizes.

[0003] A hot press molding machine includes a machine body, a hot pressing structure, a mold, and a control structure. The hot pressing structure uses heating, hydraulic pressure, and other methods to evenly press the material onto the mold. The control structure can precisely control the temperature, pressure, and time, resulting in better hot pressing molding effects.

[0004] The above-mentioned technical conditions also have the drawback that after the rubber product is hot-pressed in the mold, the rubber product is completely attached to the mold, and it is necessary to manually demold the rubber product from the mold. However, the fact that the rubber product is so attached to the mold makes the demolding process inconvenient.

[0005] Based on this, the present invention designs a hot pressing molding machine for rubber products to solve the above problems. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] A hot press molding machine for rubber products includes a machine body 1 and a mold. The mold is mounted on the machine body 1 and includes an upper mold 2 and a lower mold 7, with the upper mold 2 connected to the lower mold 7. A lifting structure 10 is provided on the machine body 1, and two lifting structures 10 are provided on the machine body 1, with the upper mold 2 positioned between the two lifting structures 10.

[0023] The machine body 1 is equipped with a movable structure 4, and the lower mold 7 is connected to the movable structure 4. The movable structure 4 is located between two lifting structures 10. The movable structure 4 moves the mold out of the machine body 1, and the lifting structures 10 lift the upper mold 2 from the lower mold 7, so that the upper mold 2 and the lower mold 7 are separated.

[0024] The lower mold 7 has a mold cavity 11 located between the upper mold 2 and the lower mold 7. A fixing groove is formed on the lower mold 7, communicating with the mold cavity 11. An air pipe 5 is installed in the fixing groove. A fixing block 12 is fixedly connected to the upper mold 2, inserted into the fixing groove, and positioned between the air pipe 5 and the mold cavity 11. When the upper mold 2 and the lower mold 7 are closed, the fixing block 12 isolates the air pipe 5 from the mold cavity 11.

[0025] The machine body 1 is equipped with an air blowing structure 6, which is connected to an air pipe 5. The air outlet of the air pipe 5 faces the mold cavity 11. When the lifting structure 10 raises and lowers the upper mold 2, the air blowing structure 6 is activated. The air blowing structure 6 generates airflow, which is blown out along the air pipe 5. Since the air outlet of the air pipe 5 faces the mold cavity 11, when the airflow is blown out from the air pipe 5, the airflow acts on the rubber product in the mold cavity 11. Under the action of the airflow, the edge of the rubber product near the air outlet of the air pipe 5 separates from the mold cavity 11, which facilitates demolding.

[0026] A reinforcing tube is fixedly connected to one end of the air pipe 5 near the mold cavity 11. A fixing block 12 is located between the reinforcing tube and the mold cavity 11. The reinforcing tube is made of heat-resistant material to prevent the air pipe 5 from being damaged by heat. A limiting strip 13 is fixedly connected to the fixing groove, and two limiting strips 13 are mirror-arranged in the fixing groove. The air pipe 5 is located between the limiting strip 13 and the fixing groove. The limiting strip 13 abuts against the air pipe 5, which restricts the movement of the air pipe 5 and increases the stability of the air pipe 5 in the fixing groove.

[0027] A fixing plate 15 is fixedly connected to the air pipe 5. A threaded rod 14 is threadedly connected to the fixing plate 15 and is threaded onto the lower mold 7. The fixing plate 15 and the threaded rod 14 increase the stability of the air pipe 5 on the lower mold 7. A mounting plate 3 is provided on the lifting structure 10, and a mounting groove 9 is formed on the mounting plate 3. A mounting rod 8 is fixedly connected to the upper mold 2, and the mounting rod 8 is above the mounting groove 9. When the lifting structure 10 is activated, the upper mold 2 is easily lifted and lowered by the lifting structure 10 under the action of the mounting plate 3, the mounting groove 9, and the mounting rod 8.

[0028] The implementation principle of this embodiment is as follows: After the rubber product is hot-pressed in the mold, the moving structure 4 is activated, the mold moves out of the machine body 1, the lifting structure 10 is activated, the upper mold 2 is lifted up, the upper mold 2 is separated from the lower mold 7, the blowing structure 6 is activated, the blowing structure 6 generates airflow, the airflow is blown out along the air pipe 5, because the air outlet of the air pipe 5 faces the mold cavity 11, the rubber product on the side of the mold cavity 11 near the air outlet of the air pipe 5 is separated from the mold cavity 11 under the action of the airflow, achieving the effect of easy demolding.
