Description
Technical field
The utility model is related to mould applications, and in particular to prevent the mold that sealing face is unedged.
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.
Utility model content
The utility model aim is to provide the sealing face of preventing unedged mold, when solving existing deep chamber generation injection molding
Exhaust mode in, since the place close to mill bottom gap on product does not have supporting surface, and gas fluidity is big, it is easy to produce
Burr is generated on product, makes the problem that injecting products are unedged.
The utility model is achieved through the following technical solutions：
The unedged mold in the sealing face of preventing includes the preceding die cap plate supported by mould rack, in the preceding die cap plate
On be provided 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, in preceding die cap plate
Lower end be provided with sequentially connected exhaust casing, stick, link block and linear driving device, the driving device is fixed on mould
Having on holder, the bottom of the link block and the driving end of driving device connect, and installation straight slot is provided at the top of link block,
The installation straight slot extends driving direction of the axis perpendicular to driving device, and the opening size for installing straight slot is less than slot bottom ruler
Very little, the bottom of the exhaust casing is connect with stick, the cross sectional dimensions of the cross sectional dimensions of the stick and installation straight slot successively,
And stick and installation straight slot cooperation, start driving device, exhaust casing can be made to be inserted into installation through-hole, and make the top of exhaust casing with
The sealing face of preceding die cap plate 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 installing the modular constructions such as straight slot and driving device dismantling connection simultaneously, after to the utility model
The maintenance of phase, reduces maintenance cost.
Further, one end of the link block being provided with baffle, the baffle closes the one end for installing straight slot,
The position opposite with installation straight slot is provided with magnet on baffle, when stick is with installation straight slot cooperation, one end of stick and baffle
Contact, and lived by magnet adsorption.
The setting of magnet improves the synchronism of link block and stick, convenient for exhaust casing propulsion and exit.
Further, the installation straight slot is T-slot.
Further, the driving device is pneumatic cylinder, and cylinder bottom connect with mould rack, piston-rod end with connect
Block connects, and when piston rod extension maximum, the top of exhaust casing and the sealing face of preceding die cap plate are coplanar.
The utility model compared with prior art, has the following advantages and advantages：
1, the mold that the utility model prevents sealing face unedged, when injection molding, in preceding die cap plate, middle die cavity body and rear mold
After cover board contacts and forms a closed chamber successively, colloid is molded into closed chamber, the gas being located at around preceding die cap plate
It is discharged from exhaust casing, 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, preceding die cap plate
Sealing face is exactly a whole plane, and when injection molding is easier to sealing, and product surface will not be unedged when injection molding, improves product
Surface quality, and conducive to product demoulding, not will produce the case where product surface is by flash garland, reduce releasing agent spraying
It is secondary；
2, the mold that the utility model prevents sealing face unedged, exhaust casing is by installing the modular constructions such as straight slot and driving
Device dismantling connection reduces maintenance cost convenient for the maintenance to the utility model later stage.
