Abstract
The utility model discloses a mould with an ejector pin. The mould comprises an upper mould, a lower mould, a sliding block component and two side inclined ejector blocks, wherein the upper mould and the lower mould are closed to form a product injection molding space, the sliding block component and the two side inclined ejector blocks are filled between the upper mould and the lower mould, the sliding block component comprises a wedge block and a sliding block body, and an upper mould ejector pin part is arranged on the upper mould corresponding to the wedge block and provided with an array ejector pin. The wedge block of the mould is provided with an ejector pin foundation pillar, the ejector pin is arranged on the upper mould ejector pin part corresponding to the wedge block, the ejector pin and the ejector pin foundation pillar are butt-jointed and matched to synchronously complete a pore structure provided with an array on a product part in the injection molding of the product part so as to complete previous two process contents in one working procedure, simultaneously the precision of products is improved, the machining working procedures of the products are reduced, the production efficiency is improved, and the production cost is reduced.
Description
[technical field]
The utility model is applied in the injecting products field, relates in particular at the injection moulding with hole array product spare and the demoulding, has the mould of pin.
[background technology]
On phone housing; bottom or side are provided with sound hole; in the enclosure; corresponding sound hole is provided with mobile microphone; voice messaging when collecting conversation; make and processing industry at existing phone housing; normally adopt the injection moulding processing mode to make phone housing; in injection moulding and knockout course; if run into the situation of the sound hole diameter of design less than 0.4mm; be to be not easy in the injection moulding releasing process, create; so in injection moulding and demoulding link, do not reserve the sound hole position; but in conjunction with the mode that adopts injection moulding and secondary operations; in order to reach product requirement; finish the predetermined design form; usually will be in injection moulding; the demoulding goes out after the product casing; carry out secondary operations again; process the sound hole structure; traditional handicraft all is to adopt laser boring; on the product casing that injection moulding is come out, get some sound holes as the array of design; if structural design has sound hole; and the shell that can't only finish by injection moulding, its Production Time is long, the processing cost height; what need is artificial many; the sound hole that designs on shell is at the different model shell; number; perhaps can be not quite similar at interval, and each punching process is finished in laser boring relatively independently; drilling technology can not precisely be controlled, the precision instability.
[summary of the invention]
The utility model has proposed a kind of sound hole structure of just producing at above problem in product casing in the injection moulding link, do not need to carry out the injection mold of secondary operations.
Described in the utility modelly relate to a kind of mould with pin, described mould comprises upper die and lower die, slide block assembly and two side slanted kicking blocks, upper die and lower die close up formation product injection moulding space, slide block assembly and two side slanted kicking blocks are filled between the upper die and lower die, slide block assembly comprises wedge block and slide body, in the patrix position, corresponding wedge block position is provided with patrix pin spare, has the array pin on patrix pin spare.
Described wedge block has an inclined-plane, and the two ends of withstanding slide body, slide body with the inclined-plane cooperate with the side slanted kicking block.
On described wedge block, be provided with some pin pilums towards the surface of patrix pin spare, described pin pilum is corresponding one by one with pin, and described pin contacts with the pin pilum and crashes behind matched moulds.
Described pin pilum is conical, and described pin is cylindrical, and the diameter on pin pilum top is greater than the diameter of pin.
Described pin pilum is cylindrical, and described pin is cylindrical, and the diameter of pin pilum is greater than the diameter of pin.
Have a patrix pin spare headspace in patrix, described patrix pin spare secure bond is in headspace.
Has the pin pilum on the wedge block of the present utility model, on the patrix pin spare of corresponding wedge block, be provided with pin, pin and the butt joint of pin pilum cooperate can be when the injection moulding of product spare, finish the pore structure of on product spare, offering array synchronously, two technology contents before in an operation, finishing, improved product precision simultaneously, reduced the product manufacturing procedure, enhanced productivity, reduce production costs.
