Description

TECHNICAL FIELD

[0001] The utility model relates to a surfboard processing technical field, and specifically is a surfboard processing mould. BACKGROUND

[0002] Surfing is a water sport in which athletes stand on a surfboard or use a belly board, a knee board, an inflatable rubber pad, a canoe or a kayak to ride the waves. A surfboard is a sports equipment used for surfing. To increase friction, a waxy outer film is applied to the surface of the surfboard. The surfboard is placed in a processing mould during the application of the outer film to facilitate injection molding. A processing mould is required for this process.

[0003] In a surfboard processing mould (Patent No. CN220373778U) disclosed in a Chinese patent, the device includes a device table and a device frame. A hydraulic cylinder is installed at the top of the device frame. The output end of the hydraulic cylinder penetrates through the device frame and is fixedly connected with a paste plate. An injection port is installed at the top of the paste plate. An injection mould is installed below the paste plate. The injection mould is fixedly connected with the top of the device table. A closing mechanism is provided inside the paste plate. The closing mechanism includes a device slot. Through the structural design of the closing mechanism, the function of closing the injection port during the upward movement of the paste plate is achieved.

This causes the liquid inside the injection port to still drip into the injection mould during the upward movement of the paste plate, thereby affecting the surfboard to be injected in the injection mould. The automation level of the device is improved. However, the device cannot automatically remove the surfboard after injection molding. Manual removal is still required, which is a waste of manpower and affects the efficiency of surfboard injection molding. SUMMARY
