Abstract

The invention provides a balancing structure of a die. The die comprises a female die side and a male die side, wherein an upper fixing plate and a female die plate are arranged on the female die side; a male die plate, an upper ejector plate, a lower ejector plate, a lower fixing plate and two foot pads are arranged on the male die side; the two foot pads are arranged between the male die plate and the lower fixing plate. The balancing structure of the die comprises two balancing blocks and a plurality of balancing columns, wherein the two balancing blocks are fixed in the female die plate and the male die plate correspondingly; the balancing blocks are opposite to a direction in which a product center deviates from a die center; the plurality of balancing columns are fixed on the outer side of the female die side and the outer side of the male die side near the balancing blocks respectively. Through the balancing structure of the die, the die is balanced through a manner of the combination of the balancing blocks and the balancing columns; when the product center deviates from the die center, the balancing structure of the die is capable of overcoming the condition with uneven stress and avoiding warping of a product.

Description

The balanced structure of mould

[technical field]

The present invention relates to a kind of balanced structure, be specifically related to a kind of balanced structure of mould.

[background technology]

The plastic parts of product can use plastic mould to carry out moulding, for example, be the plastic parts such as the shell of electronic product.Due to popularizing of electronic product, also become the problem of broad research for the improvement of plastic mould.

In the time of forming plastic cement product, product center, moulding center and mold center need be consistent could normal shaped article.But product center can depart from mold center sometimes, cause mould surface discontinuity equalization, make the product after moulding occur the phenomenons such as warpage.

In order to solve mould surface discontinuity equalization, there is the problem of warpage in product, and prior art is in mould, to increase balance weight, increases balance weight and can improve the situation of discontinuity equalization, but improve DeGrain, and whole mould is still uneven.

In view of this, be necessary to develop in fact a kind of balanced structure of mould, above-mentioned because product center departs from mold center to solve, and the discontinuity equalization occurring and the problem of product warpage.

[summary of the invention]

Therefore, the object of this invention is to provide a kind of balanced structure of mould, in the time that product center departs from mold center, the balanced structure of this mould can be improved the situation of discontinuity equalization, avoids product to occur the phenomenon of warpage.

In order to achieve the above object, the balanced structure of mould provided by the invention, described mould comprises master mold side and male model side, described master mold side has upper mounted plate and caster, described male model side has male model plate, upper ejector plate, lower liftout plate, bottom plate and is located at two foots pad between described male model plate and described bottom plate, and the balanced structure of described mould comprises:

Two balance weights, it is corresponding being fixed in described caster and male model plate respectively, and this balance weight is located on the rightabout that product center departs from mold center's direction;

Some balance columns, it is individually fixed near the master mold side outside of balance weight and male model side outside.

Preferably, in described caster and male model plate, be provided with corresponding mounting groove, located therein for described balance weight.

Preferably, described balance columns is four, and this balance columns is symmetrically fixed on described master mold side outside and male model side outside between two.

Preferably, described balance columns is the column producing after cylinder trimming, and the face after described balance columns trimming and master mold side and male model side are pasted neat.

Preferably, be respectively equipped with two screws on described balance columns, this screw coordinates screw to fix this balance columns in master mold side outside and male model side outside.

Compared to prior art, the balanced structure of mould of the present invention, it adopts the mode that balance weight and balance columns combine to carry out mould balance, strengthen the balanced capacity of mould, in the time that product center departs from mold center, can overcome the situation of discontinuity equalization, avoid product to occur the phenomenon of warpage.

Fig. 2 illustrates the balanced structure of mould of the present invention in the structural representation of male model side.

Fig. 3 illustrates the combination schematic diagram of the balanced structure of mould of the present invention.

Fig. 4 illustrates the generalized section of the balanced structure of mould of the present invention.

[specific embodiment]

Please jointly consult Fig. 1 to Fig. 4, the balanced structure that wherein Fig. 1 has illustrated mould of the present invention is in the structural representation of master mold side, Fig. 2 has illustrated the balanced structure of mould of the present invention in the structural representation of male model side, Fig. 3 has illustrated the combination schematic diagram of the balanced structure of mould of the present invention, and Fig. 4 has illustrated the generalized section of the balanced structure of mould of the present invention.

The balanced structure of mould provided by the invention, wherein said mould comprises master mold side 100 and male model side 200, described master mold side 100 has upper mounted plate 110 and caster 120, described male model side 200 has male model plate 210, upper ejector plate 220, lower liftout plate 230, bottom plate 250 and is located at two foots pad 240 between described male model plate 210 and described bottom plate 250, in the present embodiment, the balanced structure of described mould comprises:

Two balance weights 400, it is corresponding being fixed in described caster 120 and male model plate 210 respectively, in described caster 120 and male model plate 210, be provided with corresponding mounting groove, located therein for described balance weight 400, in order to keep the balance of mould, this balance weight 400 is located on the rightabout of product 300 misalignment mold center directions;

Four balance columns 500, it is symmetrically fixed on respectively master mold side 100 outsides and male model side 200 outsides near balance weight 400 between two, the column of this balance columns 500 for producing after cylinder trimming, and the face after these balance columns 500 trimmings pastes neat with master mold side 100 and male model side 200 respectively, on this balance columns 500, be also respectively equipped with two screws 510, in this two screw 510, be combined with screw to fix this balance columns 500 in master mold side 100 outsides or male model side 200 outsides.

Due to the column of described balance columns 500 for producing after cylinder trimming, therefore this balance columns 500 is processed simple and convenient, and this balance columns 500 is symmetrically fixed on respectively male model side 200 outsides and master mold side 100 outsides between two, not only can balance mould, be also convenient to die sinking and the form removal of mould.

The balanced structure of mould of the present invention, its mode that adopts balance weight 400 and balance columns 500 to combine is carried out mould balance, has strengthened the balanced capacity of mould, in the time of product 300 misalignment mold center, can overcome the situation of discontinuity equalization, avoid product 300 to occur the phenomenon of warpage.
