Description

Technical Field

[0001] The utility model relates to the field of molds, in particular to a mold of a double-density EPP seat frame with a steel wire frame. Background Art

[0002] The company's technology for dual-density EPP seat frames with steel wire skewer is relatively mature. However, current EPP molds have separate mold plates and frames, requiring assembly of the mold frame and mold for each production run. This is extremely cumbersome, and the space available is relatively limited, making them unsuitable for injection molding dual-density EPP seat frames. Currently, no suitable mold exists for this purpose.

[0003] As disclosed in the utility model with the publication (announcement) number CN207044575U, a mold for a double-density EPP seat frame with a steel wire skeleton is provided, comprising a movable mold and a fixed mold installed on an external processing device. The movable mold comprises a movable mold mounting plate, an upper movable mold template, and a movable mold heightening frame installed between the movable mold mounting plate and the upper movable mold template. The fixed mold comprises a fixed mold mounting plate, a lower fixed mold template, and a fixed mold heightening frame installed between the fixed mold mounting plate and the lower fixed mold template. Both the movable mold mounting plate and the fixed mold mounting plate are arranged on the processing equipment. A movable mold steam chamber and a fixed mold steam chamber for heating the upper movable mold template and the lower fixed mold template are respectively provided between the movable mold heightening frame and the fixed mold heightening frame. The upper movable mold template and the lower fixed mold template are also cooperated to form at least one cavity for molding the double-density EPP seat frame. The cavity is also provided with a material gun connected to an external injection mechanism.

[0004] The mold of the above-mentioned utility model can improve the production efficiency and part batch quality stability of the dual-density EPP seat frame. However, in the actual production process, the cylinder drives the moving mold plate and the fixed mold plate to perform the mold closing process, and lacks a buffer component, which causes the mold to easily undergo rigid collision during the mold closing process or the cylinder applies excessive pressure during the mold closing process, causing damage to the mold.
