Abstract

The utility model provides an internal and external composite slider for a male die, and the slider can exit bidirectionally when the die is opened. The slider comprises an outer slider, which passes through a core and a cavity to enter into the die cavity of an injection product, and the inclined plane on one side opposite to the core and the cavity is pressed with a block, which opens the die along the female die direction, and the block is fixed on a cavity plate through a screw; in addition, the outer slider is sunken with a groove on one side opposite to the core and the insert, an inner slider is selectively contained in the groove, the inner slider and the outer slider extend into the die cavity along the same direction, the top end of the inner slider is upward bent to form a reverse hook of the product, the inner slider obliquely opens the die and passes through a shift block along the inverse direction, and the shift block is fixed on the cavity plate through a screw. When the die is opened, the outer slider outward moves by dint of the block, the inner slider inward moves by dint of the shift block, thereby the inner slider and the outer slider have different journeys and leave the reverse hook at the same time, and the mutual interference problem is avoided.

Description

The inside and outside combined type slide block of male model

[technical field]

The utility model relates to the inside and outside combined type slide block of a kind of male model, especially a kind of two-way slide block structure that withdraws from overhead kick.

[background technology]

In the mould design, usually can run into this type of situation: all have overhead kick (or hole) to exist inside and outside the 3D product homonymy in the die sinking direction; in general outside overhead kick (or hole) can select for use the feature die outer slide to withdraw from overhead kick (or hole); and inboard overhead kick has only and realizes that with splaying overhead kick withdraws from; when it has only the change product structure when spatially taper pin can't withdraw from, therefore there are many limitation.With product shown in Figure 1 is that example describes, and the hole 91 of product 9 sides needs slide block to withdraw from, and the inboard of these product 9 same side has a trip 92 to need use the taper pin moulding, and then ram travel is suffered the taper pin intervention and can't be withdrawed from.

In view of this, be necessary to provide a kind of male model slide block structure that can two-wayly withdraw from fact.

[summary of the invention]

The purpose of this utility model is to provide a kind of male model inside and outside combined type slide block, and two-way withdrawing from during die sinking is in order to solve the problem that overhead kick occurs and then can't withdraw from the stroke that conventional sliders die sinking direction withdraws from.

For reaching above-mentioned purpose, the utility model comprises an outer slide, this outer slide passes public affairs, mother module core enters the die cavity of injecting products, and the oblique die sinking direction of this outer slide wears an Angle Pin, in order to the location outer slide, again, this outer slide is oppositely public, the inclined-plane of mother module core one side is pressed a branch of, this bundle piece is with the die sinking of master mold direction, and this bundle piece is fixed in caster with a screw, this outer slide is public relatively, the mother module core one side groove that caves in is installed with an inner slide in order to selectivity, and this inner slide and above-mentioned outer slide extend into die cavity in the same way, and the make progress overhead kick of bending forming product of this inner slide top, moreover, in this inner slide oblique die sinking wear a shifting block in the other direction, this shifting block is fixed in caster with a screw.

Compared with prior art, outer slide outwards moves by bundle piece and Angle Pin during the utility model die sinking, and inner slide moves inward by shifting block, staggers on the stroke and withdraws from overhead kick simultaneously, avoids occurring the problem of interference mutually.

[specific embodiment]

Please refer to Fig. 2, be the profile of utility model when the matched moulds state, it comprises an outer slide 4, this outer slide 4 passes public affairs, mother module core 7,8 enter the die cavity of injecting products 9, hole 91 in order to shaped article 9, and these outer slide 4 oblique die sinking directions (oblique outer) are offered an Angle Pin hole, in order to wear an Angle Pin 1, this Angle Pin 1 also is arranged in the caster with location outer slide 4, again, this outer slide 4 is oppositely public, mother module core 7, a branch of 5 lower side pressed on the inclined-plane of 8 one sides, this bundle piece 5 is with the die sinking of master mold direction, and caster is fixed in a screw in the top of these bundle piece 5 vertical directions, this outer slide 4 is public relatively, mother module core 7, the 8 one sides groove that caves in, be installed with an inner slide 3 in order to selectivity, this inner slide 3 extends into die cavity in the same way with above-mentioned outer slide 4, and these inner slide 3 tops are bending upwards, overhead kick 92 in order to shaped article 9, and this top is spaced a distance with the die cavity wall of relative formation overhead kick 92, be called the empty avoiding size A that overhead kick 92 is withdrawed from, simultaneously, these male model benevolence 8 relative these inner slides 3 are reserved a space, be called the empty avoiding size B that inner slide 3 slides, and A＞B, moreover, in this inner slide 3 oblique die sinking in the other direction (in oblique) offer a shifting block hole, in order to wear a shifting block 2 bottoms, caster is fixed in a screw in the top of these shifting block 2 vertical directions.

During die sinking, please refer to Fig. 3, remove Angle Pin 1, move on the caster, the bundle piece 5 with on move, outer slide 4 moves (in the present embodiment for moving to left) laterally, withdraws from the hole 91 of product 9 until this outer slide 4, simultaneously, move on the shifting block 2, inner slide 3 oppositely moves (promptly moving to right) relative to outer slide 4, and the overhead kick 92 that product 9 is withdrawed from these inner slide 3 tops heads on the die cavity wall until this top, and can take out product 9 this moment.

During matched moulds, see also Fig. 2 and Fig. 3, shifting block 2, the bundle piece 5 move down, inner slide 3 moves to left, outer slide 4 moves to right, simultaneously, Angle Pin 1 return, in order to the location outer slide 4, and then the location inner slide 3, but this moment injection molding product 9.

More than, this outer slide 4 is fixed an anti-module 6 at stroke, the male model plate of bundle piece 5 respectively at the stroke of outer slide 4.
