Description

Electronic equipment shell mould Technical Field The utility model relates to the technical field of molds, in particular to an electronic equipment shell mold. Background The plastic-coated iron injection molding product is a common injection molding product at present, the plastic-coated iron product needs to be subjected to die assembly injection molding after positioning an iron sheet on a lower die core in the processing process, the existing connecting sheet product is formed by positioning and injection molding a plurality of iron sheets, the iron sheet in the middle is shaped like a Chinese character 'kou', and all the iron sheets are wrapped into a whole by a plastic part after injection molding. As disclosed in chinese patent, publication No. CN 222387480U, an iron sheet positioning mechanism for plastic-coated iron injection mold, which is used in combination with a threaded post, a driven gear and a gear transmission assembly, can adjust the placement height of the iron sheet in the middle of the connecting sheet, and is suitable for injection molding processing of connecting sheets with different specifications. However, the mode can only adapt to the iron sheet with the corresponding hole, and when the hole on the iron sheet is round, the iron sheet is easy to incline, so that the effect of wrapping the iron sheet by the plastic part after injection molding is affected. Disclosure of utility model In view of the above, the present utility model aims at overcoming the drawbacks of the prior art, and its main purpose is to provide a mold for electronic equipment housing, which solves the problem that when an iron sheet positioning mechanism of a plastic-coated iron injection mold disclosed in CN 222387480U is adopted, when the hole on the iron sheet is circular, the iron sheet is easy to incline, so as to affect the effect of coating the iron sheet on the plastic part after injection molding. The electronic equipment shell mold comprises an upper mold and a lower mold, wherein a concave mold cavity is arranged at the upper end of the lower mold, a plurality of positioning columns are arranged in the concave mold cavity, inner grooves are formed in two opposite side walls of the positioning columns, matched clamping blocks are inserted into inner cavities of the inner grooves, elastic pieces connected with the clamping blocks are arranged in the inner cavities of the positioning columns, an iron sheet is sleeved on the positioning columns, and the clamping blocks are overlapped with the upper ends of the iron sheet when the electronic equipment shell mold is ready to be processed. Further, the inner groove at one side of the positioning column is divided into a first groove and a second groove which are aligned up and down, and clamping blocks are inserted into the first groove and the second groove. Further, the inner groove is one, and the inner groove is arranged on the upper portion of the bottom end of the positioning column, when the iron sheet is sleeved on the positioning column, the iron sheet is overlapped with the upper end and the clamping block, and the lower end of the iron sheet is overlapped on the upper end face of the concave die cavity. Further, one surface of the inner groove, which is close to the inner cavity of the positioning column, is provided with an inclined groove extending towards the outer wall of the positioning column. Further, a distance between one end of the inclined groove closest to the outer wall of the positioning column and the outer wall of the positioning column is a first interval.
