Description

Technical Field

[0001] The utility model relates to the technical field of forming molds, in particular to a processing mold for a trolley case. Background Art

[0002] A molding die, also known as a mold, is a mold made in proportion to the shape and structure of the actual object. It is a tool that uses pressing or pouring to make the material into a certain shape. Molding molds include injection molding molds, extrusion molding molds, blow molding molds for hollow products, vacuum or compressed air molding molds, compression molding molds and die-casting molds. A trolley case molding mold is a mold used to make trolley cases.

[0003] The application number is CN201922013149.4, which discloses a processing mold for a trolley case, including an upper mold for fixing the inner wall of the trolley case and a lower mold for fixing the outer wall of the trolley case. The upper mold includes an upper mold plate, a case fixing structure and a telescopic part of the fixing structure. The case fixing structure and the upper mold plate are connected by the telescopic part of the case to realize the up and down movement of the case fixing structure. The lower mold includes a lower mold plate and a side wall fixing structure. The side wall fixing structure is installed on the lower mold plate. The case fixing structure can adjust the telescopic amount according to the size of the trolley case, which is convenient for fixing the inner wall of the trolley case, and then fixing the outer side of the case through the side wall fixing structure, thereby realizing the fixation of the entire case, and by fixing the side wall of the case, the stability of the side wall of the case during trimming and punching operations is improved.

[0004] Although such a setting has a good effect of adjusting and fixing the box, the surface temperature of the box is too high after it is formed during use, making it inconvenient to remove the box from the mold. The box must be cooled before demolding, which affects work efficiency. Therefore, a cooling structure is required to cool the box just after it is formed. Utility Model Content
