Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a commutator hook forming mold. Background Art

[0002] According to the publication number "CN220462145U", the device can automatically flip and demould the mold box through the motor, connecting rod and rotating rod. The demoulding process is more stable, and the curved hooks formed in the mold will not be bumped or deformed, which reduces the loss in the production process and improves work efficiency. After the raw material is formed inside the mold box, the motor is started and the mold box is driven to rotate through the connecting rod. The other end of the mold box will also rotate on the outer wall of the fixed plate through the rotating rod. After the turning is completed, the telescopic cylinder in the middle of the mounting plate will move the push plate downward to push the curved hook inside the mold box. The demoulding is carried out, and the objects after demoulding fall on the upper end of the demoulding platform for subsequent processing. The operation is convenient and quick. Through the provided diverter pipe, connecting pipe and sprinkler head, the device can effectively cool the mold box, so that the inside of the mold box can be cooled faster, the processing time can be shortened, and the work efficiency can be improved. The water inlet pipe is connected to the external water source, and the water source enters the inside of the connecting pipe through the diverter pipe. It is sprayed out by the sprinkler head at the lower end of the mounting plate and falls on the outer surface of the mold box to cool the mold box. The sprayed water flows into the middle of the water collection tank and is recovered by the water collection tank for recycling, which saves more resources.

[0003] In the process of implementing this solution, the inventor found that the following problems in the prior art have not been well solved: the mold box is flipped by a rotating mechanism, and the hook is ejected from the mold box by a hydraulic cylinder. Before ejection, it is cooled by a spray structure to facilitate demolding. However, after spraying, the overall temperature of the mold box drops to a lower temperature. The next time the hook is formed by the mold box, a lot of heat will be taken away from the hook, resulting in a decrease in the quality of the hook and a worse molding effect. Moreover, after spraying and demolding, the spray water can easily penetrate into the mold box, causing the molten metal to mix with the cooling water during the next casting, affecting the quality after molding.
