Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
The shell structure schematic diagram that Fig. 1 is molded for the housing mould of one specific embodiment of the utility model.
Marked in accompanying drawing as follows：
Side wall 1, groove 2.
Embodiment
The utility model embodiment discloses a kind of housing mould, to avoid housing and mould vacuum suction, is easy to the demoulding,
Improve product appearance quality.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, the shell structure signal that Fig. 1 is molded for the housing mould of one specific embodiment of the utility model
Figure.
In one embodiment, the housing mould that the utility model is provided includes male model and master mold.
Formed after male model and master mold matched moulds and rectangular casing shape identical inner chamber to be formed.It should be noted that square
Shape housing refers to the rectangular in cross-section of housing, and it can be square or rectangle etc., be specifically as follows round rectangle.
The inwall of master mold is in smooth surface, with the minute surface outer wall of molded housing.Divide on the lateral wall of the different directions of male model
Multiple parallel strip projected parts are not provided with, and the cross section of strip projected parts is curved, the length directions of strip projected parts and male model
Bottom surface is parallel.At least one set of strip projected parts are respectively arranged with the side wall for namely corresponding to the side of rectangle four, every group of strip projected parts are equal
Parallel side-by-side is set, and the length direction of strip projected parts and the bottom surface of male model are parallel.The cross section of strip projected parts is curved, also
Correspond to curved with the section of plane perpendicular.
By setting strip projected parts, the groove 2 of strip, and the horizontal stroke of groove 2 are correspondingly formed during shaping on the inwall of housing
Section is in corresponding arc.Certainly, the height of strip projected parts should be less than the thickness of the side wall of housing, that is, during molded housing not
Groove can be formed, and the setting of strip projected parts should not hinder the housing after shaping to deviate from die cavity.
During the housing mould provided using the utility model, by setting strip projected parts, strip on the lateral wall of male model
Projection acts on the housing of shaping, and housing is pulled into male model during the demoulding, so as to improve the vacuum suction between housing exterior walls and master mold
Effect, it is to avoid due to the cosmetic injury that the viscous master mold demoulding of absorption is caused, significantly improve product appearance quality, and be easy to the demoulding to grasp
Make.Meanwhile, the cross section of strip projected parts is curved, while housing can be pulled to male model by arc contact surface in the demoulding, no
Can produce on stripping direction destructive obstruction to molded housing, it is to avoid during the demoulding that the housing drawing of shaping is bad.
It is preferred that, the cross section semicircular in shape of strip projected parts.Have half on the inwall of housing sidewall after corresponding shaping
Circular groove 2.Housing effectively can be pulled to male model by semi-cylindrical hill in the demoulding, and when housing is deviate from, semi-circular recesses 2 can
Gradually deviate from the radian of circular arc in male model without damaging shell structure.Certainly, the cross section side of strip projected parts as needed
Edge can also be the minor arc in other radians.
Further, strip projected parts are arranged at male model inwall at rectangular corners.Due to the demoulding when, hull outside wall
Easily occur vacuum suction close to corner and glue master mold, thus preferred strip projected parts are arranged to male model inwall close to rectangular corners
Place, so that housing effectively is pulled into male model.As needed, can respectively it be set at the two intersection on adjacent two side
Strip projected parts, the strip projected parts of both sides are engaged pulls to male model by housing.
Further, the spacing between multiple strip projected parts on the lateral wall of all directions is equal.Namely set multiple
The strip projected parts of parallel side-by-side, and strip projected parts are equidistantly distributeds.It is thus uniform from the longitudinal direction of housing to apply active force,
Housing is pulled into male model.According to the absorption situation of housing and master mold, serious position increase strip projected parts can also adsorbed
The distribution density of the strip projected parts of density, i.e. predeterminated position is more than the distribution density of the strip projected parts of other positions, predeterminated position
Can absorption situations at different levels set, further to improve the square adsorption effect of strip projected parts.
It can be set on the basis of the various embodiments described above, on master mold and at least one is provided with beryllium copper insert, beryllium copper insert
Shower is provided with individual deep hole, deep hole, the tube wall of shower and the inwall of deep hole leave gap, the end of shower and deep hole
Top leave gap.Beryllium copper is for example processed into mold insert, two deep holes are processed in mold insert, the length of shower is slightly shorter than depth
Hole.Two showers are loaded in deep hole respectively.By above-mentioned setting, temperature control effectively can be carried out to mould, place it and dissipate
Deformation of products caused by thermal effect difference, improves mould productivity ratio, extends die life, and cost is relatively low, is easy to commercial introduction
With.
Further, the annulus area that the sectional area of shower is less than or equal between spray pipe outer wall and inner walls of deep holes.
Annular cross-sectional area between the tube wall and inner walls of deep holes of shower is more than or equal to the sectional area of shower, in order in shower
Cooling water delivery port can be smoothly flowed to from gap, be then discharged out.
The embodiment of each in this specification is described by the way of progressive, and what each embodiment was stressed is and other
Between the difference of embodiment, each embodiment identical similar portion mutually referring to.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or new using this practicality
Type.A variety of modifications to these embodiments will be apparent for those skilled in the art, determine herein
The General Principle of justice can in other embodiments be realized in the case where not departing from spirit or scope of the present utility model.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide scope consistent with features of novelty.
