Description

Shoemaking mould Technical Field The utility model relates to the technical field of shoemaking, in particular to a shoemaking mould. Background With the continuous development of shoemaking industry, shoemaking dies are widely applied to molding processes such as injection molding, foaming, hot pressing and the like as core components in the production of shoe products. The existing shoemaking mould has a certain progress in structural design, production efficiency, energy consumption control and automation degree, but has a plurality of defects, and is difficult to completely meet the requirements of the modern shoemaking industry on high efficiency, high quality, low energy consumption and intelligent production. After searching, a shoemaking mould with the publication number of CN113858526B is disclosed, and the publication date is 2023, 04 and 21.

However, the scheme still has obvious defects that the cooling device depends on the control component to regulate the on-off state of the movable plug, the cooling process is intermittent rather than continuously and dynamically regulated, so that the temperature control response is delayed, the partial cooling is easy to be uneven, meanwhile, the mold opening action depends on the temperature sensed by the thermal sensing box to trigger the action of the cylinder, a real-time feedback mechanism for the internal molding state of the mold is lacking, the mold opening time cannot be accurately controlled according to the actual curing degree, the incompletely cured shoe body is easily ejected in advance, and the product yield is influenced.
