Abstract:
1. A structure of slide-block module of a plastic pallet shaping mold, said shaping mold is used for injection shaping a plastic pallet, a plurality of reinforced areas are provided in a connecting zone provided with ribs arranged transversely or longitudinally between a central area of a bearing surface of said plastic pallet and a plurality of pallet-edge supporting columns at surrounding edges on said plastic pallet, said reinforced areas each is composed of a plurality of slide-block modules provided at relatively opposite positions on said shaping mold, wherein: each of said slide-block modules includes a fixed block and at least a slide block, a bottom of said fixed block is provided with a fixed portion fixed on said shaping mold, a beveled guiding portion is provided and extended upwards above said fixed portion, a vertically directing shaping area is provided between said guiding portion and said fixed portion; said slide block is provided with an obliquely extended sliding connecting portion being oblique in opposition to said guiding portion, so that said slide block is able to be provided slidably on said fixed block; a bottom of said slide block is located above said shaping area to obscure said shaping area from above, thereby said shaping area and said bottom of said slide block are formed between them a mold cavity for injection shaping of said reinforced area, after injection shaping of said reinforced area, by obliquely sliding moving of said slide block on a lateral side of said fixed block, said bottom of said slide block move upwards far away from said shaping area, thereby said reinforced area is able to be released from said shaping mold smoothly.
