Abstract

The utility model provides an internal parting mold for making split bumpers. The internal parting mold comprises a mold body, wherein the mold body comprises a front mold and a rear mold, the parting surface of the mold body is located on a R root corresponding to the two side edges of a bumper on the front mold and the rear mold, two upper and lower cavities respectively corresponding to an upper bumper main body and a lower bumper main body are arranged in the mold body, and the two cavities are arranged in parallel. The internal parting mold provided by the utility model has the beneficial effects that the parting surface of the mold is located on the R root to avoid a parting line in a visible region of a finished product, so that the product is more beautiful, and meanwhile, the upper bumper main body and the lower bumper main body can be made by one mold, so that the cost is saved and the problem that chromatic aberration is generated easily when the upper main body and the lower main body are produced by two molds.

Description

Make interior minute mould of Split type bumper

Technical field

The utility model relates to a kind of interior minute mould making Split type bumper.

Background technology

In order to improve the competitiveness of car load, highlight attractive in appearance, atmosphere, the individual character, high-end of car load.The design style of bumper is just more next diversified, and structure is installed more and more hidden change.So just there is Split type bumper.Split type bumper is to design in order to highlight the style characteristic of car load, compares so with overall formula bumper, and Split type bumper more can be given prominence to attractive in appearance, atmosphere, the individual character, high-end of car load.But manufacture is had higher requirement to mould, it is first the increase of cost.By an original mold, become two molds, cost almost will double.Secondly mould structure need to solve the mounting structure of the more and more hidden change of product.Also have two molds to produce product and can produce aberration, product probably can increase spraying coating process.

In addition as shown in Figure 2,4, traditional parting Surface Design is at the largest contours line position of product, directly die sinking of mould, simply processing aspect of mould structure.But in product die joint position, be viewing area, can leave parting line, affect the outward appearance of bumper.

Summary of the invention

Problem to be solved in the utility model is to provide a kind of interior minute mould making Split type bumper, can solve the inner part line of product in viewing area, affect the problem of outward appearance, utilize a mold to produce the body up and down of Split type bumper simultaneously simultaneously, having solved making Split type bumper cost increases, and product exists the problem of aberration.

Attractive in appearance for product integral body, inner part line is placed in to non-viewing area, the technical scheme adopting is: interior minute mould making Split type bumper, comprise mold, described mold comprises cephacoria and rear mold, the die joint of described mold is positioned at described forward and backward film corresponding to the R root at described bumper both sides of the edge places, and described R root refers to that cambered surface that place, bumper bar both sides of the edge is transitioned into inner surface by bumper outer surface is positioned at the position of inner surface.Because this position is positioned at bumper bar inner surface, thus bumper bar be assembled on automobile after its parting line just hidden.

For solving making Split type bumper, need two molds, the problem that cost increases, the technical solution adopted in the utility model is: in described mold, have two cavitys up and down that correspond respectively to body under bumper upper body and bumper, described two cavity parallel arrangements.

But adopt the mould of this film two cavity configurations, mould itself is certain to very large, can the molar that meet injection molding machine require this to become again a new problem, addressing this problem will be in the situation that guaranteeing mould strength, the ranking of rational deployment product, mould as far as possible design is little, and the one, for loss of weight, the 2nd, in order to guarantee not newly increase large size plastic jetting-moulding device.The technical scheme of for this reason taking is: described upper cavity has the convex position corresponding with the stage portion of protrusion on described bumper upper body, convex position in described upper cavity down, described lower chamber has the convex position corresponding with the stage portion of protrusion on body under described bumper, and the convex position in described lower chamber upward.Described convex position upward and described convex position down over against.The project organization that such layout both can have been simplified mould facilitates the making of die joint; Can reduce labor content again, convenient processing; Can also save die space, be mould loss of weight, guaranteed the outfit of mould and injection molding machine.

Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, make finished product viewing area there is no parting line, product is more attractive in appearance, have reduced in addition the cost of making Split type bumper, and the product of producing does not exist aberration.

The specific embodiment

As shown in Figure 1, the utility model provides a kind of interior minute mould making Split type bumper, comprises mold, and mold comprises cephacoria 4 and rear mold 5, and the die joint 6 of mold is positioned at forward and backward

film

4,5 corresponding to the R root at place, bumper both sides of the edge.R root refers to that cambered surface that bumper bar both sides of the edge places is transitioned into inner surface by bumper outer surface is positioned at the position of inner surface.Because this position is positioned at bumper bar inner surface, thus bumper bar be assembled on automobile after its parting line just hidden.

In mold, there are 1,2, two

cavity

1,2 parallel arrangements of two cavitys up and down that correspond respectively to body under bumper upper body and bumper.Two cavitys of same mould, have solved the cost of making bumper.

In order not make, volume because of mould itself is excessive need to increase large-scale injection-moulding device, layout to upper and

lower cavity

1,2 is optimized, upper cavity 1 has the convex position 11 corresponding with the stage portion of protrusion on bumper upper body, convex position 11 in upper cavity down, lower chamber 2 has the convex position 21 corresponding with the stage portion of protrusion on body under bumper, and the convex position 21 in lower chamber upward.Convex position upward 21 and convex position 11 down over against.

Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
