Abstract

The utility model provides a barb disposing structure, which is applied to a mold composed of a female die and a male die that are arranged oppositely and can be opened and closed. A molding space is preset between the female die and the male die, and a finger cam is arranged through the male die, one end of the finger cam is arranged two limiting grooves and connected with a movable block on which two limiting pins are arranged. In addition, two positioning pins also are arranged on the male die. When the product exits from the forming product, the movable block can be moved along the positioning pins, and the limiting pins can be moved on the limiting grooves come-and-go, thereby making the movable block and the figure cam exited from the forming production together. The utility model has simple structure and is suitable for exiting the product having the special barb structure.

Description

A kind of barb is handled structure

Technical field

The utility model relates to a kind of mould structure, and particularly a kind of barb is handled structure.

Background technology

When utilizing mould-forming process to make plastic product, need to utilize the mould structure of making in advance, and the plastics of fusion are injected among the mould to reach the purpose of shaped article by injection machine.

As shown in Figure 1, be the side view of inclined pin structure in the existing mold when the shaped article.Wherein, but this mould reserves a molding space between this male model 10 and this master mold 20, in order to shaped article 30 by being oppositely arranged and the male model 10 and the master mold 20 of folding are formed.In addition, this male model 10 runs through and is provided with a taper pin 201, and these taper pin 201 1 ends participate in shaped article 30.

In the die sinking process, this taper pin 201 withdraws from shaped article 30, when the product 30 of need moulding has as shown in the figure barb 301 structures, uses this taper pin 201 can not withdraw from shaped article 30, and this just must handle structure by a kind of novel barb of design.

Summary of the invention

In view of the above problems, the utility model has disclosed a kind of novel barb and has handled structure, and this structure is used to withdraw from the product with special barb.

For reaching above-mentioned purpose, the utility model has adopted following technical scheme: a kind of barb is handled structure, this structure is mainly used in the mould, this mould mainly comprises a male model and a master mold, but this male model and this master mold is oppositely arranged and folding, and reserve the space of a shaped article between this male model and this master mold, in addition, also run through being provided with a taper pin on this male model, this taper pin one end is connected with a taper pin seat, its another end offers two stopper slots, and should also be connected with a movable block on the end, corresponding these stopper slots are provided with two spacer pins on this movable block, again, also be provided with two alignment pins on this male model, so, when product withdrawed from shaped article, this movable block can move along these alignment pins, these spacer pins can move back and forth on these stopper slots, thereby this movable block and this taper pin end can withdraw from shaped article.

Above-mentioned technical scheme is not only simple in structure, and can solve the difficult problem that can not withdraw from the shaped article with special overhead structure with general taper pin.

Description of drawings

Fig. 2 is a side view of the present utility model

The specific embodiment

See also shown in Figure 2ly, be side view of the present utility model.Wherein, the utility model is mainly used in one to have in the mould of male model part and master mold part, this master mold part mainly comprises a caster 40, be combined with a mother module core 401 on it, this male model part mainly comprises a male model plate 60, be combined with a male model benevolence 601 on it, but this caster 40 is oppositely arranged and folding with this male model plate 60, and should public affairs, set in advance effigurate molding space between the

caster

60 and 40, it utilizes an injection machine (not shown) that the plastics of fusion are injected in this molding space, can mold the product consistent with this molding space shape 50.

In addition, this male model plate 60 is away from a side and a upper ejector plate 604 adjacent settings of this caster 40, and this upper ejector plate 604 and liftout plate once 605 be adjacent lays equal stress on to stack and puts, on these, following

liftout plate

604 and 605 is provided with a taper pin seat 603, in addition, run through in this male model plate 60 and be provided with a strip taper pin 602, these taper pin 602 1 ends are fixedlyed connected with this taper pin seat 603 with a screw, and should can on this taper pin seat 603, move back and forth by end, its another end 6021 is stretched and is placed in the above-mentioned molding space, flexibly connect a movable block 6022 on this end 6021, this movable block 6022 and these end 6021 fellowship shaped articles 50, and this movable block 6022 is provided with two spacer pins 6024, in addition, corresponding these spacer pins 6024 offer two stopper slots 6023 on this end 6021, when this movable block 6022 and this end 6021 participates in or withdraws from shaped article 50, these spacer pins 6024 can move back and forth on these stopper slots 6023, to limit the stroke that this movable block 6022 participated in or withdrawed from product 50.

Again, this male model benevolence 601 is provided with two springs 607, these springs 607 a wherein end link to each other respectively with two alignment pins 606, when movable block 6022 returns, can make above-mentioned alignment pin 606 play the effect of buffering, its other end is integrated these springs 607, these alignment pins 606 and this male model benevolence 601 by two grub screws 608, helps adorning mould.

After the dispensing end (not shown) of make-up machine is filled molding space, it is formable products 50, in mould die sinking process, at first should public affairs,

caster

60 and 40 is opened certain space, when the ejection system (not shown) of board with this mould on, when following

liftout plate

604 and 605 up pushes away, an end that drives this taper pin 602 moves on this taper pin seat 603, its another end 6021 upwards and to the direction that withdraws from shaped article 50 moves, because the guide effect of this alignment pin 606 and the position-limiting action of this stopper slot 6023, movable block 6022 on this taper pin 602 only moves upward along this alignment pin 606 earlier, these spacer pins 6024 move with respect to this end 6021 on these stopper slots 6023, so, this movable block 6022 is to the direction motion of withdrawing from shaped article 50, this movable block 6022 is with these taper pin 602 motions, until this product 50 is ejected molding space at last.

Otherwise, when the mould return, before contacting with caster 40, male model plate 60 touches caster 40 by the release link (not shown) that is loaded in the mould structure on upper and

lower liftout plate

604 and 605 earlier, promote upper and

lower liftout plate

604 and 605 move downward reach return after, the movable block 6022 that this taper pin 602 drives on it moves together, and this spacer pin 6024 is moved on this stopper slot 6023, thereby gets back to the matched moulds state, so far, mold actions is finished a complete cycle.

Claims

1. a barb is handled structure, this structure is mainly used in the mould that comprises a male model and a master mold, but this male model and this master mold is oppositely arranged and folding, and reserve the space of a shaped article between this male model and this master mold, in addition, also run through being provided with a taper pin on this male model, this taper pin one end is connected with a taper pin seat, it is characterized in that:
