Abstract

The utility model discloses a novel mould structure, which is used in a mould comprising a male die and a female die, wherein, the mould product space is arranged between the male die and the female die. The male die comprises a lift-out plate which is arranged one side face of the male die of opposite to the female die, a mould base that is arranged close to the lift-out plate, an ejector sleeve which comprises an ejector sleeve imbedding needle, wherein, one end of the ejector sleeve imbedding needle is fixed on the mould base, while the other end is provided with a copper insert and extends into the mould space, and the bottom end and the copper insert cooperate to form the mould product. An ejector sleeve lining capable of sliding up and down along the ejector sleeve imbedding needle is arranged outside the ejector sleeve imbedding needle. One end of the ejector sleeve lining is fixed on the lift-out plate, while the other end contacts with the mould product and lift out the mould behind the mould product. The utility model does not need a hot melt jig assisting process and saves processing time and physical resources.

Description

A kind of novel mould structure

Technical field

The utility model has disclosed a kind of novel mould structure, particularly a kind of mould structure of taking charge of tube.

Background technology

As shown in Figure 1, common die generally comprises a master mold 10 and a male model 20, between this master mold 10 and this male model 20, be the molding space of plastic product 30, also run through on this male model 20 and be provided with department's tube, this department's tube comprises pin 201 in department's tube, pin 201 1 ends 2013 are fixedly set on the male die seat 203 in this department's tube, its another end 2011 is stretched and is placed in the above-mentioned molding space and participate in shaped article 30 directly, and the pin 201 outer department's tube linings 2012 that are arranged with in this department's tube, when utilize an injection machine (not shown) with the plastics of fusion after the glue-feeder 101 by the cold runner system is injected into above-mentioned molding space under the certain pressure, be formable products 30, and the product 30 of this forming ejected this mould by this department tube lining 2012.

Utilize a hot melt tool (not shown) that one bronze medal mold insert is carried out hot melt at last and handle, and the product 30 of forming is sheathed on the copper mold insert behind this hot melt, so, this copper mold insert can be bumped in the product 30, to obtain complete finished product.

Above-mentioned technical scheme shaping finished product not only needs a hot melt tool secondary process, and production capacity is low, fraction defective is high.

Summary of the invention

In view of the above problems, the utility model has disclosed a kind of novel mould structure, and this structure is not only simple, and does not need hot melt tool secondary process, has saved process time and material resources.

For reaching above-mentioned purpose, the utility model has adopted following technical scheme: a kind of novel mould structure, but this structure be mainly used in comprise that a male model and a master mold are oppositely arranged and the mould of folding in, and reserve a molding space between this male model and this master mold, in order to shaped article, again, this male model comprises a liftout plate, a die holder and department's tube.Wherein, this liftout plate be arranged at this male model and this master mold back to a side on, the adjacent setting of this liftout plate with this die holder.In addition, this department's tube mainly comprises pin in department's tube, and pin one end is fixed on the above-mentioned die holder in this department's tube, is arranged with a bronze medal mold insert on its another end and stretches to place in this molding space this end and this copper mold insert fellowship shaped article; Reach one and take charge of a tube lining, it is sheathed on outside the interior pin of above-mentioned department tube and can slides up and down along this department interior pin, and this department's tube lining one end is fixed on the above-mentioned liftout plate, and its other end contacts with shaped article, and behind shaped article product is ejected mould.

Adopt above-mentioned technical scheme, a kind of novel mould structure that the utility model is mentioned does not only need a hot melt tool secondary process, and simple in structure, saves process time.

The specific embodiment

Please refer to shown in Figure 2ly, be combination schematic diagram of the present utility model.The utility model is mainly used in the mould with master mold part and male model part, reserves a molding space between this master mold part and this male model part, in order to shaped article 40.

Wherein, this master mold partly comprises a caster 50, be combined with a mother module core 501 on it, this master mold part also is provided with a cold runner system 70, this cold runner system 70 runs through this master mold part, and the glue-feeder on it 701 is relative with above-mentioned molding space, and is injected in the molding space with shaped article 40 with the mode of the glue into of the hiding plastics with fusion.

In addition, this male model partly comprises a male model plate 60, be combined with a male model benevolence 601 on it, this male model plate 60 and this caster 50 back to a side be provided with a liftout plate 602, and this liftout plate 602 and a die holder 603 adjacent settings, in addition, this male model partly runs through and is provided with strip department tube, this department's tube comprises pin 604 in department's tube, one end 6043 is fixed on the die holder 603, its another end 6041 is through grinding and magnetization, forming minim gap is sheathed on this end 6041 to cooperate the columned copper mold insert 402 that will be hollow in, and should pass liftout plate 602 respectively by end 6041, male model plate 60 and male model benevolence 601, stretch place in this molding space and with its on copper mold insert 402 fellowship shaped articles 40, so, this copper mold insert 402 can correspondence be bumped in this product 40, again, these department's tube 604 outer department's tube linings 6042 that are arranged with, this department's tube lining 6042 can slide up and down along pin 604 in this department's tube, and the one end is fixed on this liftout plate 602, its other end ejects mould in order to when sliding up and down in the lump with shaped article 40 and this copper mold insert 402.

After 701 pairs of molding spaces of glue-feeder of cold runner system 70 are filled, it is formable products 40, in the die sinking process, at first this male and female template 50 and 60 is opened certain space, this liftout plate 602 is moved upward by the effect of an ejecting structure (not shown), a drive department tube lining 6042 moves upward, and the product 40 and the copper mold insert 402 of forming ejected mould in the lump.
