Description
Technical field
The present invention relates to mould applications, and in particular to easily demoulding depth cavity mould.
Background technology
Injection molding is a kind of method of industrial products production moulding.Product is usually using rubber injection mold and plastic injection.Injection molding
Molding die platen press and casting die can also be dispensed.Injection (mo(u)lding) machine (abbreviation injector or injection molding machine) is by thermoplastic or heat
The main former of variously-shaped plastic products is made using mould for plastics for solidity material, and injection molding is to pass through injection molding
Machine and mold are realized.
In the packaging of the bottles class such as some white wine, in order to improve shockproof coefficient and delicately packed degree, plastic casing is often selected
As its packing box.Plastic casing in production, is formed by the injection molding into mold and then cooling forming with definite shape, body
Long-pending box body, since the length of bottle class is big, for dies cavity depth it is also big, injection molding when, due to preceding die cap plate, in
Die cavity body and rear mold cover board contact and are formed a closed chamber, when liquid is molded into closed chamber from rear mold, meeting successively
Certain gas is retained around preceding die cap plate, the presence of gas can influence the surface quality of injecting products.In order to reduce retain with
Bottom 0.03mm or so is ground in negative influence of the air to product surface quality in cavity, scene in the glue position sealing glue position of preceding die cap plate
Gap be used to store retention gas in the cavity.This exhaust mode, since the place close to mill bottom gap on product does not have
There is supporting surface, and gas fluidity is big, it is easy to generate burr on product, keep injecting products unedged.When product is unedged,
Easy mold release is not allowed not only, is also easy in demoulding, garland product, and increase the spraying frequency of ingot stripper.
Invention content
Present invention aims at easily demoulding deep cavity mould is provided, exhaust side when existing deep chamber generates injection molding is solved
In formula, since the place close to mill bottom gap on product does not have supporting surface, and gas fluidity is big, it is easy to be generated on product
Burr makes the problem that injecting products are unedged.
The present invention is achieved through the following technical solutions：
Easily demoulding depth cavity mould, includes the preceding die cap plate supported by mould rack, is set on the preceding die cap plate
It is equipped with installation through-hole, the sealing face of preceding die cap plate upper end is connected to by the installation through-hole with lower end surface, under preceding die cap plate
End is provided with sequentially connected exhaust casing, installation axle, link block and linear driving device, and the driving device is fixed on mold
On holder, the bottom of the link block and the driving end of driving device connect, and mounting hole is provided at the top of link block, described
The axis of mounting hole is parallel to the driving direction of driving device, and the bottom hole of mounting hole is provided with magnet, the bottom of the exhaust casing
Portion and one end of installation axle connect, and the other end of the installation axle is inserted into mounting hole and is contacted with magnet, and the magnet will
Installation axle adsorbs, and starts driving device, and exhaust casing can be made to be inserted into installation through-hole, and makes the top of exhaust casing and preceding die cap plate
Sealing face it is coplanar.
When injection molding, after preceding die cap plate, middle die cavity body and rear mold cover board contact successively and form a closed chamber, to
Colloid is molded in closed chamber, the gas being located at around preceding die cap plate is discharged from exhaust casing, is thus not necessarily in preceding die cap plate
The gap of glue position sealing glue position mill bottom 0.03mm or so, as soon as the sealing face of preceding die cap plate is exactly a whole plane, when injection molding, more holds
Easy sealing, product surface will not be unedged when injection molding, improves the surface quality of product, and conducive to the demoulding of product, will not produce
The case where raw product surface is by flash garland reduces releasing agent spraying number.
Exhaust casing is by the modular constructions such as installation axle, magnet and driving device dismantling connection simultaneously, after to the present invention
The maintenance of phase, reduces maintenance cost.
Further, the cross section of the mounting hole is rectangle, the cross sectional dimensions of the installation axle and the cross of mounting hole
Sectional dimension is consistent.
The cross section of mounting hole and installation axle is rectangle, is avoided in driving exhaust casing movement, exhaust casing is around peace
Fill the axis rotation of axis.
Further, the driving device is pneumatic cylinder.
Compared with prior art, the present invention having the following advantages and advantages：
1, the easily demoulding deep cavity mould of the present invention, when injection molding, preceding die cap plate, middle die cavity body and rear mold cover board successively
After contacting and forming a closed chamber, it is molded colloid into closed chamber, is located at the gas around preceding die cap plate from exhaust casing
Discharge is thus not necessarily to grind the gap of bottom 0.03mm or so in the glue position sealing glue position of preceding die cap plate, and the sealing face of preceding die cap plate is just
It is a whole plane, when injection molding is easier to sealing, and product surface will not be unedged when injection molding, improves the surface matter of product
Amount, and conducive to the demoulding of product, not will produce the case where product surface is by flash garland, reduce releasing agent spraying number；
2, the easily demoulding deep cavity mould of the present invention, exhaust casing pass through the modular constructions such as installation axle, magnet and driving device
Dismantling connection reduces maintenance cost convenient for the maintenance to the later stage of the invention.
