SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art and provide the injection mold for positioning the sheet, which solves the problem of poor release of the sheet during injection molding and improves the injection molding efficiency.
The purpose of the utility model is realized by the following technical scheme:
the utility model provides an injection mold of location sheet, includes A board and the B board that links to each other, still includes unsteady mold insert, mould meat and connecting block, the connecting block is provided with location portion, the connecting block passes through location portion and connects unsteady mold insert, unsteady mold insert is connected with mould meat.
Furthermore, the injection mold for positioning the sheet material further comprises a supporting plate, and the supporting plate is connected with the connecting block.
Furthermore, the connecting block is provided with a first hard block and a second hard block, and the first hard block and the second hard block are respectively embedded into the supporting plate and are fixedly connected with the supporting plate.
Furthermore, the connecting block is also provided with a fixing block, and the fixing block is used for being fixed with the supporting plate.
Further, a hard sheet is arranged on the side face of the floating insert and used for supporting the whole floating insert.
Furthermore, a cavity is formed between the plate A and the plate B, and a product is injected and molded in the cavity.
Compared with the prior art, the utility model has the following advantages and beneficial effects:
according to the utility model, the floating insert retreats by 2mm to form a sheet placing area, the A plate and the B plate are used for injection molding glue to position a product before complete die assembly, so that the sheet is fixed, then complete die assembly is carried out, injection molding is completed, the obtained product cannot be badly molded due to sheet deflection in the injection molding process, the badness of sheet injection molding release is solved to a great extent, and the injection molding efficiency is greatly improved.
