Description

Technical Field

[0001] This utility model relates to the field of valve core production technology, specifically a valve core mold clamping device. Background Technology

[0002] A valve core mold is a specialized mold used to manufacture valve cores. As a critical component of a valve, the quality and performance of the valve core directly affect the overall performance and service life of the valve. A valve core mold typically consists of multiple components, including a mold base, mold core, guide pillars, and guide sleeves. These components work together to form a complete mold cavity for molding the valve core. The mold's structural design must consider factors such as the shape, size, material, and manufacturing process of the valve core to ensure that the molded valve core meets design requirements. As one of the key pieces of equipment in valve production, the design and manufacture of valve core molds require extremely high technical expertise.

[0003] For example, the device, named "Anti-Leak Inner Tube Valve Core" in announcement number CN201050620Y, includes a valve plug with an arc-shaped cap. The cap has a recess on top, the valve handle is fitted with a spring, inserted into the valve guide, and covered with a half-cap nut with a built-in sealing gasket. The valve handle is threaded. The half-cap nut has internal threads that mate with the external threads of the valve guide.

[0004] During the use of the above-mentioned device, it takes a long time to wait for the mold surface temperature to drop during the production process, which leads to a decrease in production efficiency and cannot meet the current market demand. Therefore, we propose a valve core mold clamping device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a valve core mold clamping device to solve the problem mentioned in the background art that the existing device requires a long time to wait for the mold surface temperature to drop during the production process, which leads to reduced production efficiency and cannot meet the current market demand.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a valve core mold clamping device, a support platform, a support leg provided at the lower end of the support platform, and the support leg being welded to the support platform, a connecting column provided at the upper end of the support platform, and the connecting column being fixedly connected to the support platform, and two sets of the connecting column being provided.

[0007] Also includes:

[0008] A sliding groove is formed on the surface of a connecting column. A drive motor is mounted on the upper end of the connecting column and is fixedly connected to the connecting column. A threaded rod is installed inside the sliding groove, and one end of the threaded rod is connected to the output end of the drive motor. A threaded sleeve is installed on the surface of the threaded rod and is threadedly connected to the threaded rod. A bearing seat is connected to the end of the threaded rod and is rotatably connected to the threaded rod. A connecting block is provided on the surface of the threaded sleeve and is fixedly connected to the threaded sleeve. An upper mold is provided on one side of the connecting block and is fixedly connected to the connecting block.

[0009] Preferably, the bottom of the support leg is provided with a base plate, and the base plate is fixedly connected to the support leg; the inner side of the support leg is provided with a crossbeam, and the crossbeam is fixedly connected to the support leg.

[0010] Preferably, a sliding rod is provided inside the sliding groove, and the sliding rod passes through a threaded sleeve and is connected to the inner wall of the sliding groove.

[0011] Preferably, the upper surface of the support platform is provided with a lower mold, and the lower mold is fixedly connected to the support platform.

[0012] Preferably, a water tank is provided at the upper end of the support platform, and the water tank is movably connected to the support platform. A water inlet pipe is provided at the upper end of the water tank, and the water inlet pipe is fixedly connected to the water tank.

[0013] Preferably, the surface of the water tank is equipped with spray heads, and three sets of spray heads are provided.

[0014] Preferably, a controller is mounted on the surface of the support platform, and the controller is fixedly connected to the support platform.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model incorporates a drive motor that rotates a connected threaded rod, which in turn rotates a threaded sleeve. This causes the threaded sleeve to move vertically, which in turn moves a connecting block, ultimately moving the upper mold. This separation of the upper and lower molds facilitates rapid cooling of the valve core inside the mold, making it easier to remove the formed valve core from the upper mold and improving work efficiency. Furthermore, the inclusion of a water tank and spray nozzles allows the spray nozzles to be activated during mold separation, evenly spraying water from the tank onto the valve core surface for auxiliary cooling. This significantly enhances the device's practicality and overcomes the drawback of traditional devices that require prolonged waiting times for the mold surface temperature to drop, leading to reduced production efficiency.
