Abstract
The invention relates to an injection molding die comprising an upper die insert part, an upper die insert pin, a lower die insert part and a lower die insert pin. The upper die insert part is provided with a sliding hole accommodating the upper die insert pin, and the upper die insert pin is capable of sliding in the sliding hole to contact with or separate from the lower die insert pin; the lower die insert part is provided with a sliding hole accommodating the lower die insert pin; the injection molding die further comprises an elastic part located in the accommodating hole and is pressed to the lower die insert pin upwardly, the upper and lower die insert pins are squeezed elastically, the penetrating surface clearances are avoided, and product is prevented from burr producing.
Description
Technical field
The present invention relates to a kind of injection forming mold, particularly relate to its upper and lower mould pin a kind of and there is the injection forming mold touching and wear.
Background technology
At present, in injection forming mold manufacturing process, due to the topology requirement of product, the perforation of touching of product must be accomplished without burr.When volume production product, touch the upper and lower mould pin worn collide for a long time owing to having, very easily cause upper and lower mould pin defect, final production goes out to be with deckle-edged bad product, need frequently replace with, counterdie pin, so die cost, product quality and benefit be certainly will have influence on, product cost rising, profit decline caused.
So, be necessary that a kind of new injection forming mold of design is to solve the problems of the technologies described above.
Summary of the invention
The object of the present invention is to provide a kind of injection forming mold removing product burr.
For realizing aforementioned object, the present invention adopts following technical scheme: a kind of injection forming mold, it comprises patrix mold insert, patrix pin, counterdie mold insert and counterdie pin, described patrix mold insert is provided with the sliding eye of collecting patrix pin, described patrix pin can move up and down to contact with counterdie pin or be separated in sliding eye, described counterdie mold insert is provided with the accepting hole of collecting counterdie pin, and described injection forming mold also comprises and is positioned at accepting hole and is also upwards pressed on elastic component on counterdie pin.
Injection forming mold of the present invention also comprises and is positioned in accepting hole and is upwards pressed on elastic component on counterdie pin, when injection forming mold matched moulds, on, counterdie pin presses together, formation is touched and is worn, the elasticity that counterdie pin overcomes elastic component under the extruding of patrix pin moves down, make, counterdie pin elasticity presses together, touch the face of wearing and can not produce gap, so product can not produce burr, during injection forming mold parting, after patrix pin moves up, counterdie pin moves up under the elastic restoring force of elastic component, the burr of further removal product, so, improve product quality, improve productivity effect.
Accompanying drawing explanation
Fig. 1 is the partial schematic diagram after injection forming mold matched moulds of the present invention.
Detailed description of the invention
Refer to shown in Fig. 1, injection forming mold 100 of the present invention comprises patrix mold insert 10, patrix pin 20, counterdie mold insert 30, counterdie pin 40 and an elastic component 50.
Patrix mold insert 10 is provided with the sliding eye 11 of collecting patrix pin 20, and patrix pin 20 can slide up and down at sliding eye 11, and counterdie mold insert 30 is provided with the accepting hole 31 of collecting counterdie pin 40, and counterdie pin 40 side is provided with boss 41.
Elastic component 50 is butterfly spring packing ring, be contained in accepting hole 31, elastic component 50 is provided with the through hole 51 passed for counterdie pin 40 and the elastic portion 42 being around in through hole 41 periphery, and elastic portion 42 is upwards pressed on boss 41, and elastic portion 42 has 0.15mm and pops up space.
When injection forming mold 100 matched moulds, upper and lower mould pin 20,40 presses together, formation is touched and is worn, the elasticity that counterdie pin 40 overcomes elastic component 50 under the extruding of patrix pin 20 moves down, upper and lower mould pin 20,40 elasticity is pressed together, product 200 touches the face of wearing and can not produce gap, so can not produce burr.During injection forming mold 100 parting, after patrix pin 20 moves up, counterdie pin 40 moves up under the elastic restoring force of elastic component 50, removes the burr of product 200 further, so, improves product 200 quality, improves productivity effect.
In other embodiments, elastic component 50 can be set to spring or metal clips etc.
Although be example object, disclose the preferred embodiment of the present invention, but those of ordinary skill in the art will recognize, when not departing from scope and spirit of the present invention disclosed in appending claims, various improvement, increase and replacement are possible.
