Abstract
The utility model discloses a battery case forming die. A slope is formed at the joint of the base and the lug boss of the die; a groove is formed in the lug boss of the die; a metal insert corresponding to the groove in size and used for air exhaust is mounted in the groove; an oriented exhaust hole is formed on the metal insert; a miniature exhaust hole is formed on the side surface of the lug boss of the die; and four threaded hole for fixing are formed on the base of the die. The utility model solves the problems in the prior that the stretching height of a material during thermal forming is not sufficient and the air displacement is low; as a slope design is adopted at the joint of the lug boss and the base of the die, the stretching value is reduced; and in virtue of the metal insert mounted in the groove of the die, the air displacement in the thermal forming process is increased, so as to guarantee the surface smoothness of products and improve the product quality.
Description
Technical field
The utility model relates to a kind of mould, and especially a kind of battery case forming mould that is applicable to belongs to the thermoforming technology field.
Background technology
Utilizing mould to make in the process of material thermoforming; Because material has certain amount of tension; Thereby material is being carried out be easy to cause when the degree of depth stretches the damage of material, under the certain situation of quantity of material, the stretching that how to promote material highly is the emphasis of present technical staff's research.
In addition, in the process of material thermoforming, how to get rid of the air between material and the mould, material is fitted just on the mould fully, the requirement that reaches thermoforming also is a problem demanding prompt solution.
Summary of the invention
In order to address the above problem, the utility model provides a kind of mould that is used for thermoforming, can not only promote the stretching height of material, and can effectively get rid of the air between material and mould, makes product surface Paint Gloss.
In order to address the above problem, the technical scheme that the utility model is taked is:
A kind of battery case mould, the junction of the base of said mould and mould lug boss is provided with a slope, is provided with a groove in the lug boss of said mould, in said groove, be equipped with one with the corresponding metal inserted piece that is used for exhaust of its size.
Aforesaid a kind of battery case mould: it is characterized in that: the inclination angle on said slope is 45 °.
Aforesaid a kind of battery case mould: it is characterized in that: said groove is a rectangle.
Aforesaid a kind of battery case mould: it is characterized in that: described metal inserted piece is provided with oriented steam vent.
Aforesaid a kind of battery case mould: it is characterized in that: the side of the lug boss of said mould is provided with small steam vent.
Aforesaid a kind of battery case mould: it is characterized in that: the base of described mould is provided with 4 screwed holes that are used for fixing.
The beneficial effect of the utility model is: through adopting ramp designs at the lug boss of mould and the connecting portion of mold base; Make material under the highly identical situation that stretches; Amount of tension has diminished, and has effectively avoided material damaged, and the metal inserted piece that has oriented steam vent that when thermoforming, the gas utilization that is difficult in the middle of the product getting rid of is arranged in the groove is discharged; Strengthen capacity, improved the quality of product.
Description of drawings
Fig. 1 is the vertical view of the utility model battery case mould;
Fig. 2 is the profile of Fig. 1 along the A-A line.
The specific embodiment
To combine Figure of description below, the utility model will be further described.
As illustrated in fig. 1 and 2; A kind of battery case mould that the utility model provides, the base 1 of said mould is provided with a slope 3 with the junction of the lug boss of mould, and the inclination angle on slope 3 can be set different angles according to actual needs; The inclination angle angle that the utility model adopts is 45 °; This oblique angle in the die drawn district designs the compensation rate that has increased material, has reduced the amount of tension of material, thereby can promote the stretching height of material.
Be provided with a groove 2 in the lug boss of said mould; In said groove 2, be provided with one with the corresponding metal inserted piece that is used for exhaust of its size; Wherein, The position of groove 2 and shape need the concrete shape set according to mould; Also can be that diverse location at mould is provided with a plurality of difform grooves simultaneously, the metal inserted piece that is used for exhaust of respective shapes is installed in groove then, the mould that the utility model provided position therebetween be provided with a rectangular groove that is used to install metal inserted piece.Said metal inserted piece is provided with oriented steam vent, and is provided with small steam vent in the side of the lug boss of mould.In the thermoforming process, because material receives the effect of HTHP, can be fitted on the mould rapidly, if the air between material and the mould is not discharged fast, then the edge of product can be uneven.
The mould that the utility model provides is when thermoforming, and the air between material and the die edge position is discharged through the small steam vent of mould lug boss side.And in the thermoforming process; Usually fit earlier in the edge that all is material and mould; Thereby cause the air of middle part to discharge; But in the utility model, the air of middle part is effectively discharged through the metal inserted piece that is installed in the groove, thereby has guaranteed that the product surface after the thermoforming is smooth.
In sum, this mould that the utility model provides can not only effectively promote the stretching height of material, and can effectively drain the air between the material and mould in the thermoforming process, has strengthened capacity, has improved the quality of product.
More than show and described basic principle, principal character and the advantage of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
