Abstract
The utility model relates to a plastic mould special for a fingerprint identification system transmitting part, which comprises an upper mould and a lower mould, wherein a fan-shaped bulge is arranged on the upper mould; a fan-shaped groove is formed on the lower mould; the size of the fan-shaped bulge is matched with that of the fan-shaped groove; a fan-shaped die cavity is formed between the fan-shaped bulge and the fan-shaped groove; and the fan-shaped die cavity is connected with a feed inlet. The plastic mould has the characteristics of simple structure and capability of effectively improving the transparency and light transmission of a finished product.
Description
Technical field
The utility model relates to a kind of plastic mould, is specifically related to a kind of plastic mould that is exclusively used in the fingerprint recognition system light transparent member.
Background technology
Be installed on the light transparent member in the fingerprint recognition system, need be than higher transparent, light transmission, but, present plastic mould adopts the die cavity of straight shape that light transparent member is carried out moulding, therefore, the light transparent member of institute's moulding, the transparency, light transmission is lower, is difficult to satisfy the production requirement of fingerprint recognition system.
The utility model content
In order to overcome the deficiencies in the prior art, it is a kind of simple in structure that the utility model provides, and can effectively improve the properties of transparency of moulding product, the plastic mould of light transmission.
In order to achieve the above object, the technical solution adopted in the utility model is as follows:
A kind of plastic mould that is exclusively used in the fingerprint recognition system light transparent member, comprise upper die and lower die, described patrix is provided with fan-shaped projection, described counterdie is provided with scalloped recess, described fan-shaped projection and scalloped recess size are complementary, and form fan-shaped die cavity between fan-shaped projection and the scalloped recess, described fan-shaped die cavity is connected with charging aperture.
As preferably, the inside of described counterdie also is equipped with demoulding pushing block, and the shape and the scalloped recess at described demoulding pushing block top are complementary.
As preferably, the bottom of described demoulding pushing block is connected with push rod.
As preferably, the bottom of the junction of charging aperture and fan-shaped die cavity is connected with thimble.
As preferably, patrix and counterdie are equipped with cooling pipe.
As preferably, described charging aperture is located on the side of fan-shaped die cavity.
The utility model compared with prior art, the straight shape die cavity prior art is modified into fan-shaped die cavity, can improve the flowability of liquid plastic, suppressed the generation of the bubble in the finished product greatly, reduced the quantity of gas line, made finished product have very high transparent, light transmission; And, demoulding pushing block also has been installed in counterdie, can allow finished product eject counterdie fully, make finished surface not produce clamp; Cooling pipe all has been installed in the upper die and lower die, can have been controlled the precision of finished product easily and shorten molding cycle.
Description of drawings
Fig. 1 is a kind of structural representation that is exclusively used in the plastic mould of fingerprint recognition system light transparent member of the utility model embodiment;
Fig. 2 is the A-A line cutaway view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, a kind of plastic mould that is exclusively used in the fingerprint recognition system light transparent member, comprise patrix 1, counterdie 2, described patrix 1 is provided with fan-shaped protruding 11, described counterdie 2 is provided with scalloped recess 21, described fan-shaped protruding 11 are complementary with scalloped recess 21 sizes, and fan-shaped protruding 11 with scalloped recess 21 between the fan-shaped die cavity 10 of formation.Be specially, fan-shaped protruding 11 are located at the bottom of patrix 1, scalloped recess 21 is located at the top of counterdie 2, and, fan-shaped protruding 11 the height of the depth ratio of scalloped recess 21 is bigger, when patrix 1 during with counterdie 2 matched moulds, fan-shaped protruding 11 and scalloped recess 21 between will have a cavity, described cavity is fan-shaped die cavity 10.
Be connected with charging aperture 6 on the side of described fan-shaped die cavity 10.Finished product 100 moulding in fan-shaped die cavity 10.Charging aperture 6 is connected with thimble 5 with the bottom of the junction of fan-shaped die cavity 10.
The inside of described counterdie 2 is equipped with demoulding pushing block 3, and the shape and the scalloped recess 21 at described demoulding pushing block 3 tops are complementary.Be specially, a through hole 22 can be offered in the middle part of counterdie 2, demoulding pushing block 3 is made into through hole 22 sizes to be complementary then, and promptly demoulding pushing block 3 can slide in through hole 22, finished product 100 is ejected from counterdie 2, and do not make finished product 100 surfaces produce clamp.For increase demoulding pushing block 3 on push power, the bottom of described demoulding pushing block 3 is connected with push rod 4.
In order to control and to shorten molding cycle the precision of finished product 100, patrix 1 and counterdie 2 are equipped with cooling pipe 7.
The course of work of present embodiment is as follows:
Liquid plastic enters fan-shaped die cavity 10 from charging aperture 6, and liquid plastic flows in fan-shaped die cavity 10 swimmingly, under the effect of cooling pipe 7, accurately controls the formed precision and the molding cycle of finished product 100.When liquid plastic becomes finished product 100, open patrix 1, utilize a side of thimble 5 pushing-off products 100,, utilize demoulding pushing block 3 that finished product 100 is ejected from counterdie 2 fully then, finish whole forming process.
The foregoing description is the more preferably specific embodiment a kind of of the utility model, and the common variation that those skilled in the art carry out in the utility model scheme scope and replacing all should be included in the protection domain of the present utility model.
