Abstract
The utility model discloses a thin-wall injection mold, which comprises a cover plate (10), an upper die (2), a lower die (5), an insert (8) and a power device, wherein the cover plate (10) is arranged above the lower die (5); the upper die (2) is arranged between the cover plate (10) and the lower die (5); a sprue sleeve (1) is arranged in the cover plate (10); the upper die (2) and the lower die (5) are combined to form a die cavity (9); the insert (8) is arranged in the lower die (5); the power device is arranged at the bottom of the inset (8) and used for driving the insert (8) to move; a guide sleeve (3) is arranged in the upper die (2); a guide column (4) is arranged in the lower die (5); and the guide column (4) moves along the guide sleeve (3) so as to control the die combination direction. By adopting the power device to drive the insert to move, the thin-wall injection mold disclosed by the utility model improves the problems that the surface of a product is sunk and uneven and not good in filling, etc, increases the structural strength and surface gloss of the product and improves the quality of the product, simultaneously the device is simple in structure, novel in design and practical.
Description
Technical field
The utility model belongs to the injection molding technology field, is specifically related to a kind of thin-walled plastic injection mold.
Background technology
Present injecting products is for weight reduction, reduction materials cost, and the wall thickness of product is more and more thinner.Injecting products generally includes matched moulds, injection melt, cooling, die sinking taking-up product in the process of injection mo(u)lding.Due to the restriction of long 7 Thickness Ratios of stream, common injection mold is difficult to carry out the thin-walled injection moulding moulding.
Present thin-walled injection moulding moulding normally utilizes special-purpose high speed injection machine to realize, plastic melt injects mold cavity with very high speed and realizes larger stream length/Thickness Ratio, but special-purpose high speed injection machine high cost.
