Description
Technical field
The utility model is related to injection mold field more particularly to a kind of detachable injection molds.
Background technology
Injection mold, is in plastics processing industry and plastic molding press is mating, assigns plastic products with complete configuration and essence
The instrument of true size.During injection, for clamping mould on injection molding machine, molten plastic is injected into pattern intracavitary, and is cooled down in intracavitary
Sizing, then upper and lower mould separates, and product is left mold from die cavity ejection via ejection system, last mold, which recloses, to carry out down
Once it is molded.For power low voltage power MOS modules, COMO low pressure and low power MOS modules or other low pressure and low power MOS modules
During being prepared, existing mold is to be poured into from top by slurry in mold, that is to say, that mould when by injection slurry
The opening of tool be on the top, after slurry imports mould inside, then with covering in die cover, natural cooling, still, this mold
It is easy to damage above plastic pattern when slurry rear cover mold lid is injected, simultaneously as opening is larger, one
A little dusts, impurity can be fallen into model, cause the final product quality finally prepared unqualified.
Utility model content
The purpose of this utility model is that：Opening to solve to prepare mold in the prior art is this mold on the top
It is easy to damage above plastic pattern when slurry rear cover mold lid is injected, simultaneously as opening is larger, one
A little dusts, impurity can be fallen into model, cause the underproof problem of the final product quality finally prepared, and the utility model provides
A kind of plastic packaging molding die for the processing of low pressure and low power MOS modules.
The technical solution of the utility model is as follows：
A kind of molding die for the processing of low pressure and low power MOS modules, including template and shaping in shaping lower template, shaping
Cope plate, detachable connection between template, detachable between shaping upper plate and shaping lower template in shaping lower template, shaping
Formula connects；Template is frame-shaped in the shaping, and the shaping lower template is equipped with the depressed area for engaging template in shaping, recessed
The height in sunken area is identical with the height of template in shaping, and the side of template and shaping upper plate is respectively equipped with to phase negative side in shaping
To concave open slot one and open slot two, open slot one and open slot two collectively constitute injection hole.
The application method of the utility model is：Before perfusion, will prepare the corresponding electrode slice of MOS low pressure and low power MOS modules,
Control terminal is put into mold, and electrode slice, control terminal are located in groove and control terminal pilot trench respectively, if the length of control terminal
Degree is longer, and corresponding, the edge for being molded lower template also is provided with corresponding control terminal pilot trench；Then will be molded in lower template, shaping
Template and shaping lower template link together, and moulded pulp enters from injection hole by depressed area, shaping mesolow power MOS modules
In the space of the upper low pressure and low power MOS modules composition of shaping.Diverge to template after the slurry curing of injection, take out prepare into
Product clean mold.
Further, template includes shaping front apron, shaping rear baffle, shaping right baffle-plate and the right gear of shaping in the shaping
Plate, detachable connection between the shaping front apron and shaping right baffle-plate and shaping right shell body, the shaping rear baffle and institute
State detachable connection between shaping right baffle-plate and shaping right shell body.It is easy to removal and installation using detachable connection, also just
The demoulding after injection further ensures the quality of finished product.
Specifically, the shaping lower template and the main body of shaping upper plate are square, and four corners for being molded lower template are set
There is through hole one, four corners of template are equipped with through hole two in the shaping, and four corners of the shaping upper plate are equipped with through hole
Three, through hole one, through hole two and through hole three are corresponding, and through hole one, through hole two and through hole three are connected by screw.
Further, the shaping front apron and shaping rear baffle are equipped with to place the electricity of low pressure and low power MOS modules
The groove of pole is equipped with to place the control terminal pilot trench of control terminal, shaping between the shaping right baffle-plate and shaping right shell body
The lug boss that bottom surface on cope plate is equipped with the groove and control terminal pilot trench, the two neighboring control terminal pilot trench it
Between be equipped with straight slot, the bottom of the shaping upper plate is equipped with and matched second lug boss of straight slot.Due to the matter of control terminal
Amount is very light, and during injection, the plastics of flowing are with small impact force, and the second raised portion fits straight slot is by control terminal
It is further fixed, it is therefore prevented that the minor rotation that occurs during plastic shaping of control terminal causes last product
It can not use.
Preferably, the shape of the injection hole of the injection hole is flat pattern, and the height of flat pattern is 3-5mm.
The flat pattern of 3-5mm will not damage injection molding block convenient for being separated with injection molding block.
Preferably, depressed area lower section template is the metal material that thickness is 2-3mm.After the completion of injection, in order to more
Quickly so that plastics solidification, can heat the bottom for being molded lower template so that plastics solidification is fast, so under depressed area
The thinner thickness of square template, in specific implementation process, the preferential Steel material for using high intensity so that the longer life expectancy of recessed portion.
In conclusion the beneficial effects of the utility model are as follows：
(1) the opening change of original mold has been arrived side by the utility model, and mold slowly enters, and reduces bubble
It generates, and is to get well die package to pour again in advance, avoid the entrance of impurity, dust so that the finished product prepared
Qualification rate higher.Although seeming the improvement very little of the utility model, nobody has found this problem before.In addition, lower die
The structure of tool and die cover has changed over three-decker, can split into multiple fractions between three-decker, after dismantling, not deposit
In the corner for being inconvenient to clean so that substantially without remaining slurry in mold.
(2) it is easy to removal and installation using detachable connection, the demoulding after injection is also allowed for, is further ensured into
The quality of product.
(3) due to the very light weight of control terminal, during injection, the plastics of flowing carry small impact force,
Second male cooperation straight slot is further fixed control terminal, it is therefore prevented that control terminal during plastic shaping
Minor rotation, which occurs, causes last product that can not use.
(4) flat pattern of 3-5mm will not damage injection molding block convenient for being separated with injection molding block.
(5) after the completion of injection, in order to more quickly so that plastics solidification, can add the bottom for being molded lower template
Heat so that plastics solidification is fast, so the thinner thickness of depressed area lower section template.
