Abstract
The utility model relates to the technical field of dies, and particularly relates to a screw-type cooling structure of a long-service-life and high-precision die. Compared with the prior art, the screw-type cooling structure disclosed by the utility model has the characteristics that through setting a screw-shaped heat-dissipating plate at the outer end of a cavity, the heat-dissipation area of the heat-dissipating plate is expanded through the screw-shaped setting, so that a product in the cavity can be cooled quickly, thereby achieving the cooling effect required by products, preventing the deformation and inward sinking of products, and improving the precision and qualified rate of products.
Description
Technical field
The present invention relates to technical field of mold, particularly a kind of long-life high-precision mold screw-type cooling structure.
Background technology
Along with the development of industrial technology, because plastic material has advantages such as shaped article is fast, the prices of raw and semifnished materials are low, plastic material more and more is applied in the industrial production field, and as various capacitor shells etc., these all need the former of mould of plastics.
Middle product at the die cavity of these mould of plastics needs quick cooling after moulding, when the high-speed molding of mould, the temperature of cover half cavity plate can raise rapidly, produce thermal expansion thus, cause the product easy deformation indent in the die cavity, had a strong impact on the qualification rate of product, after service time is elongated, die cavity also can produce distortion, and after it surpassed certain degree when this distortion, whole cover half cavity plate was namely scrapped.
Summary of the invention
For solving in the prior art in the die cavity product dispel the heat existing defective and problem, provide a kind of long-life high-precision mold screw-type cooling structure.
The technical scheme that the present invention adopts for its technical problem of solution is: long-life high-precision mold screw-type cooling structure of the present invention comprises upper die and lower die, between patrix and counterdie, be provided with die cavity, be provided with heat sink in described die cavity outer end, described heat sink is the screw-type shape.
The invention has the beneficial effects as follows: compared with prior art, long-life high-precision mold screw-type cooling structure of the present invention is by establishing the heat sink that is the screw-type shape in the die cavity outer end, enlarge the area of dissipation of heat sink by the screw-type shape, thereby the product in the die cavity can be cooled down fast, reach the needed cooling effect of product, prevent product distortion indent, improved precision and the qualification rate of product.
Description of drawings
Below in conjunction with the drawings and specific embodiments long-life high-precision mold screw-type cooling structure of the present invention is described further.
Fig. 1 is the structural representation of long-life high-precision mold screw-type cooling structure of the present invention.
The specific embodiment
As shown in Figure 1, long-life high-precision mold screw-type cooling structure of the present invention comprises patrix 1 and counterdie 2, between patrix 1 and counterdie 2, be provided with die cavity 3, be provided with heat sink 4 in die cavity 3 outer ends, heat sink 4 is distributed in the outside and the upper end of die cavity 3, heat sink 4 is the screw-type shape, and the heat sink 4 that is the screw-type shape has enlarged area of dissipation greatly.Product in the die cavity 3 is when high-speed molding, can produce a large amount of heats, temperature in the die cavity 3 can raise rapidly, and product needs to carry out cooling after moulding, not so product easy deformation indent, cause the product easy deformation indent in the die cavity, had a strong impact on the qualification rate of product, therefore need 4 pairs of die cavities 3 of heat sink to dispel the heat fast, enlarge the area of dissipation of heat sink 4 by the screw-type shape, thereby the product in the die cavity 3 can be cooled down fast, reach the needed cooling effect of product, prevent product distortion indent, improved precision and the qualification rate of product.
, but should be understood that under the situation that does not break away from relevant protection domain defined by the claims that those skilled in the art can make change and/or revise according to embodiments of the invention describing the present invention property and nonrestrictive description.
Claims (1)
1. a long-life high-precision mold screw-type cooling structure comprises upper die and lower die, is provided with die cavity between patrix and counterdie, it is characterized in that, be provided with heat sink in described die cavity outer end, described heat sink is the screw-type shape.
