Description

Reduce the mould of product parting line

Technical field

The utility model relates to technology of die manufacturing field, is specifically related to the mould reducing product parting line.

Background technology

In design of Die Casting, under the prerequisite ensureing shaped article inherent feature (such as rib, groove etc.), the parting line of product surface be made more few better as far as possible.Have the place of parting line, product will inevitably produce either large or small burr, this just needs the operation increasing product deburring, wastes time and energy, also add manufacturing cost.In actual production process, sometimes because of caused by certain reason, certain position on mould has to split mold insert, such as, certain Pocket Machining of mould is dark, when being forbidden to freeze and can not fall face, can only be made up by the way splitting mold insert, after splitting mold insert, product surface is easy to produce burr, very difficult removal.

Utility model content

Based on this, be necessary to provide a kind of mould reducing product parting line, its product parting line produced is less, can reduce the cost removing burr.

In order to realize the purpose of this utility model, the utility model by the following technical solutions:

Reduce a mould for product parting line, it is characterized in that, comprising: front mould, rear mold, front cavity and rear cavity, the first working face of described rear cavity is provided with a groove, is provided with cross muscle in the middle part of described groove; Also comprise mold insert, cavity is provided with between the bottom of described groove and the second working face of described rear cavity in described rear cavity, described second working face and described first working face are oppositely arranged, and described mold insert is inserted in described cavity, and closely cooperates with described rear cavity; The end face both sides that described mold insert coordinates with the second working face of described rear cavity are respectively equipped with boss, and described rear cavity and described boss correspondence position are provided with containing groove, and described boss is located in described containing groove.

Wherein in some embodiments, between the bottom land of described boss and described containing groove, there is predeterminable range.

Wherein in some embodiments, described predeterminable range is 1-10mm.

Wherein in some embodiments, the size of described mold insert is greater than the size of described groove.

The mould of minimizing product parting line described in the utility model, its compared with prior art:

This mould is provided with groove at the first working face of rear cavity, cross muscle is provided with in the middle part of described groove, cavity is provided with bottom rear cavity inner groovy and between the second working face of rear cavity, mold insert is inserted in above-mentioned cavity, thus the not through rear cavity of mold insert, adopt the mode of this blind edge, die is not cut logical, product has just lacked parting line, the position burr that product has parting line will reduce, namely by mold insert, mould is obtained to remedy, additionally reduce the burr that product surface is unnecessary, reach the effect made the best of both worlds.The both sides of mold insert are provided with boss, and this boss can share the impulsive force of mold insert end face and die top correspondence position, the intensity of protection die.

Accompanying drawing explanation

Fig. 1 is the mould core structure schematic diagram of the mould reducing product parting line described in the utility model embodiment;

Fig. 2 be in Fig. 1 A place along the partial sectional view of X-X line.

Detailed description of the invention

For the ease of understanding the utility model, below with reference to relevant drawings, the utility model is described more fully.Preferred embodiment of the present utility model is given in accompanying drawing.But the utility model can realize in many different forms, is not limited to embodiment described herein.On the contrary, provide the object of these embodiments be make the understanding of disclosure of the present utility model more comprehensively thorough.

Unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present utility model understand usually.The object of the term used in description of the present utility model herein just in order to describe specific embodiment, is not intended to be restriction the utility model.

Please refer to Fig. 1 and Fig. 2, the mould of minimizing product parting line described in the utility model, comprise front mould, rear mold, front cavity (not shown) and rear cavity 30, first working face 31 of rear cavity 30 is provided with a groove 32, be provided with cross muscle 33 at the middle part of groove 32, thus produce the structures such as convex tendon at product opposite position.This mould 100 also comprises mold insert 40, cavity (not shown) is provided with between the bottom of rear cavity 30 inner groovy 32 and the second working face 34 of rear cavity 30, second working face 34 of rear cavity 30 and the first working face 31 are oppositely arranged, mold insert 40 is inserted in cavity, and closely cooperate with rear cavity 30, the sidewall of the rear cavity 30 namely in the sidewall of mold insert 40 and cavity fits together.The size of mold insert 40 is greater than the size of groove 32.Because mold insert 40 is inserted in above-mentioned cavity, thus the not through rear cavity 30 of mold insert 40, adopt the mode of this blind edge, die is not cut logical, product has just lacked parting line, and the position burr that product has parting line will reduce, and namely by mold insert 40, mould is obtained and remedies, additionally reduce the burr that product surface is unnecessary, reach the effect made the best of both worlds.

The end face both sides that mold insert 40 coordinates with the second working face 34 of rear cavity 30 are respectively equipped with boss 42, and rear cavity 30 and boss 42 correspondence position are provided with containing groove 35, and boss 42 is located in containing groove 35.This boss 42 can share the impulsive force of mold insert 40 end face and rear cavity 30 top correspondence position, the intensity of protection rear cavity 30.In the present embodiment, have predeterminable range between the bottom land of boss 42 and containing groove 35, this predeterminable range is 1-10mm.

Tightr for making mold insert 40 coordinate with die 30, be provided with fastener (not shown) in the side, middle part of mold insert 40, correspondingly on die 30, be provided with draw-in groove, fastener and draw-in groove cooperatively interact, and closely mold insert 40 and die 30 are combined together.

The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
