[0006] This utility model provides the following technical solution: a rubber product molding device, including a base plate, a support frame fixedly connected to the upper surface of the base plate, an electric push rod fixedly connected to the lower surface of the support frame, a connecting plate fixedly connected to the output end of the electric push rod, an upper mold fixedly connected to the lower surface of the connecting plate, the interior of the base plate being hollow and having two slots on its upper surface, a threaded rod rotatably connected between the two inner side walls of the base plate, a threaded sleeve threaded onto the surface of the threaded rod, a sliding rod fixedly connected between the two inner side walls of the base plate, a sliding sleeve slidably fitted onto the surface of the sliding rod, and both the sliding sleeve and the threaded sleeve can move within the slots. A horizontal plate is fixedly connected between the upper surfaces of the sliding sleeve and the threaded sleeve. Two lower molds are fixedly connected to the upper surface of the horizontal plate. The lower molds are matched with the upper molds. Two sets of first springs are fixedly connected to the inner bottom wall of each lower mold. An inclined block is fixedly connected to the top of the corresponding two sets of first springs. A top plate is fixedly connected to the top of each of the two inclined blocks. Movable grooves are opened on the sides of the two lower molds. Insert rods are slidably sleeved inside the two movable grooves. Sliding grooves are opened on the inner bottom walls of the two lower molds. Sliding sliders are slidably connected inside the two sliding grooves. Top rods are fixedly connected to the upper surfaces of the two sliding sliders.

[0007] Preferred technical solution 1: A motor is fixedly installed on the side of the base plate, and the output end of the motor extends into the interior of the base plate and is fixedly connected to one end of the threaded rod.

[0008] This solution allows the horizontal plate and two lower molds to move via the rotation of the motor, facilitating continuous operation.

[0009] Preferred technical solution 2: Rollers are provided at the top of both top rods, and second springs are fixedly connected between the two sliders and the inner sidewalls of the two slide grooves. The surface of the top plate is in contact with the inner wall of the lower mold.

[0010] This solution facilitates the ejection of the molded rubber product and makes it easy to remove the finished product.

[0011] Preferred technical solution 3: A fan is fixedly installed on the upper surface of the support frame, and air outlet pipes are connected to both sides of the fan. The two air outlet pipes are fixedly connected to both sides of the connecting plate, and air nozzles are connected to the bottom ends of the two air outlet pipes.

[0012] This solution facilitates the cooling of raw materials for rubber products, thereby accelerating their molding process.

[0013] Preferred technical solution four: Both of the air outlet pipes are corrugated pipes that can be extended and shortened.

[0014] This design allows the device to extend and retract as the connecting plate rises and falls, making it easy to use.

[0015] Preferred technical solution five: A controller is fixedly installed on the upper surface of the base plate, and the motor and the fan are both electrically connected to the controller.

[0016] This solution allows for convenient control of each component and facilitates operation.

[0017] Compared with the prior art, this utility model provides a rubber product molding device with the following beneficial effects: During use, the rotation of the motor drives the threaded rod to rotate, thereby moving the threaded sleeve and the horizontal plate. This moves the lower mold on the left side of the horizontal plate below the upper mold. Then, the motor stops rotating, and high-temperature raw material is injected into the lower mold. The extension of the electric push rod then moves the connecting plate and the upper mold downwards, allowing the upper and lower molds to engage and press out the rubber product. Simultaneously, during the molding process, the operation of the fan sprays air through the air outlet and nozzles to cool the upper and lower molds, thus accelerating the molding of the rubber product. After molding is complete, the retraction of the electric push rod moves the upper and lower molds... The mold is separated, and then the motor rotates in the opposite direction, driving the horizontal plate to move to the left. This moves the lower mold on the left side out from under the upper mold, and moves the lower mold on the right side under the upper mold, allowing the rubber product to continue being extruded and molded. The process does not require machine downtime and is highly efficient. At the same time, by pushing the insert rod on the lower mold on the left side inward, it drives the ejector rod and roller to move. Through the inclined plane of the inclined block, the inclined block and the ejector plate move upward, thus ejecting the rubber product inside the lower mold for easy removal. This device can continuously perform rubber product molding operations without machine downtime, is highly efficient, and can easily and quickly eject the molded rubber product for easy removal of the finished product, making it convenient to use.

A horizontal plate 10 is fixedly connected between the upper and lower molds 5. Two lower molds 11 are fixedly connected to the upper mold 5. The lower molds 11 are matched with the upper mold 5. Two sets of first springs 12 are fixedly connected to the inner bottom wall of each lower mold 11. An inclined block 13 is fixedly connected to the top of the corresponding two sets of first springs 12. A top plate 14 is fixedly connected to the top of the two inclined blocks 13. Movable grooves 15 are opened on the sides of the two lower molds 11. Insert rods 16 are slidably sleeved inside the two movable grooves 15. Sliding grooves 17 are opened on the inner bottom wall of the two lower molds 11. Sliding sliders 18 are slidably connected inside the two sliding grooves 17. A top rod 19 is fixedly connected to the upper surface of the two sliders 18.

[0024] Example 2: The difference between this example and Example 1 is that a motor 20 is fixedly installed on the side of the base plate 1. The output end of the motor 20 extends into the interior of the base plate 1 and is fixedly connected to one end of the threaded rod 6. The rotation of the motor 20 can drive the horizontal plate 10 and the two lower molds 11 to move, which facilitates continuous operation.

[0025] Example 3: The difference between this example and Example 1 is that the top of each of the two push rods 19 is provided with a roller, and the two sliders 18 and the inner sidewalls of the two slide grooves 17 are fixedly connected with a second spring 21. The surface of the top plate 14 is in contact with the inner wall of the lower mold 11, which facilitates the ejection of the molded rubber product and the removal of the finished product.

[0026] Example 4: The difference between this example and Example 1 is that a fan 22 is fixedly installed on the upper surface of the support frame 2, and air outlet pipes 23 are connected to both sides of the fan 22.

Then, the motor 20 stops rotating, and high-temperature raw material is injected into the lower mold 11. The extension of the electric push rod 3 then moves the connecting plate 4 and the upper mold 5 downward, allowing the upper mold 5 and the lower mold 11 to engage and extrude the rubber product. Simultaneously, during the molding process, the operation of the fan 22 sprays air through the air outlet 23 and the air nozzle to cool the upper mold 5 and the lower mold 11, thereby accelerating the molding of the rubber product. After molding is complete, the retraction of the electric push rod 3 separates the upper mold 5 and the lower mold 11. Then, by rotating the motor 20 in the opposite direction, the horizontal plate 10 is moved to the left, thereby moving the lower mold 11 on the left side out from under the upper mold 5. The lower mold 11 on the right side is moved to under the upper mold 5, so that the rubber product can continue to be extruded and molded. The process does not require stopping and waiting, and the efficiency is high. At the same time, by pushing the insert rod 16 on the lower mold 11 inward, it drives the ejector rod 19 and roller to move. Through the inclined surface of the inclined block 13, the inclined block 13 and the top plate 14 move upward, thereby ejecting the rubber product inside the lower mold 11, making it easy to remove the rubber product. When using this device, rubber product molding operations can be carried out continuously without stopping and waiting, which is highly efficient. At the same time, it can easily and quickly eject the molded rubber product, making it easy to remove the finished product and convenient to use.
