Description
Technical field
The present invention relates to injection molding technology fields, more specifically, it relates to a kind of side pumping mould.
Background technology
Injection mold is a kind of tool producing plasthetics;Also plasthetics complete structure and accurate dimension are to confer to
Tool.Injection molding is to produce a kind of processing method used when certain complex-shaped components in batches.It refers specifically to melt heated
Plastics by injection molding machine high pressure inject die cavity obtain formed products after cooling and solidifying.
Authorization Notice No. is that the Chinese utility model patent of CN203726748U discloses a kind of side core-pulling injection mold,
Drip irrigation device be include dynamic model assembly, cover half assembly and side core-pulling mechanism, between moving platen and solid plate formed be used for
The die cavity of injection molding, side core-pulling mechanism include side slide, inclined guide pillar, limit assembly, latch segment and the side being fixed on side slide
Core, inclined guide pillar are fixed on top clamping plate, and side slide is equipped with the oblique guide hole with inclined guide pillar sliding cooperation, and inclined guide pillar passes through fixed
Template is fixedly connected with top clamping plate.
The side core-pulling injection mold is realized that side is twitched using parts such as sliding block, inclined guide pillar and side cores and is made；In injection moulding process
In, since the plastics of melting have higher temperature, to improve production efficiency, it will usually open up cooling water in template and mode
Road it is not open close enter cooling water cool down with accelerate product cooling and shaping；And side core-pulling is as composition portion important in mold
Point, if could not cool down in time, micro deformation may occur after it is heated and influence product to formed product precision.
Invention content
In view of the deficiencies of the prior art, present invention aims at a kind of side pumping mould is provided, have to side core-pulling into
Row is cooling to improve the effect of Product Precision.
To achieve the above object, the present invention provides the following technical solutions：
A kind of side pumping mould, including side core-pulling；Sliding block has been bolted in the side core-pulling, and the sliding block slides grafting
Inclined guide pillar；Several cooling holes are drilled in the inside of the side core-pulling, the cooling hole is directed toward the molding end face of side core-pulling；Institute
It states and is drilled with the parallel core water channel that it is molded end face and is connected to all cooling holes inside side core-pulling；In the core water channel two
Sidetracking has the channel communicated therewith；It is drilled with two sliding block water channels being connected to respectively with two channels in the sliding block, two
A sliding block water channel is separately connected water inlet interface and drainage interface.
It is arranged such so that be connected to inside sliding block and side core-pulling, by cooling water after water inlet interface is passed through, cooling water flows through
Be discharged from drainage interface after sliding block water channel, channel, core water channel and cooling hole, so as in time to side core-pulling and sliding block into
Row cooling；It prevents that micro deformation occurs to influence the dimensional accuracy of injecting products because of side core-pulling overheat.
Further setting：It is provided with positioning table on the end face abutted with the sliding block on the side core-pulling, in the cunning
The locating slot being inserted into for the positioning table is offered on the end face abutted with the side core-pulling on block.
So set, being inserted into locating slot by positioning table so that the contact position both when sliding block is connect with side core-pulling is accurate
Really, it is docked accurately to ensure channel with sliding block water channel, there is preferable concentricity.
Further setting：Company between the side core-pulling and the sliding block, positioned at the channel and the sliding block water channel
The place of connecing is provided with sealing ring.
So set, improving leakproofness by adding sealing ring, prevent from leaking with the place of docking of sliding block water channel in channel
Water phenomenon and influence mold normal work.
Further setting：The annular groove being put into for the sealing ring, the sealing are offered on the end face of the sliding block
Circle side is abutted with the bottom surface of the annular groove, and the other side is abutted with the end face of the side core-pulling.
So set, by adding annular groove, to realize the positioning to sealing ring.
Further setting：Mounting blocks have been bolted on cope plate, have tiltedly been led described in the mounting blocks interference grafting
Column；The via passed through for the inclined guide pillar is offered on the sliding block.
So set, passing through mounting blocks interference grafting inclined guide pillar so that mounting blocks are integrally formed with inclined guide pillar, consequently facilitating
Inclined guide pillar is mounted on cope plate；Inclined guide pillar pass through via so that during opening mould and compounding mould inclined guide pillar to sliding block in mistake
The power applied in hole can push sliding block to slide, to realize side pumping and side into action.
Further setting：The relief hole stretched into for the inclined guide pillar is offered in lower template.
It is the movement slot milling of inclined guide pillar, when avoiding inclined guide pillar long and lower die so set, by the way that relief hole is arranged
Plate is answered back to；Ensure that inclined guide pillar is fully inserted into sliding block simultaneously, so that contact area of the two after molding is reached maximum, reduction is answered
Power is concentrated.
Further setting：Boss is provided on the sliding block, the outside side wall of the boss is inclined to set and opens up
There are mounting groove, the mounting groove that cushion block has been bolted；The inside side wall of the mounting blocks is inclined to set, after molding,
The inside side wall of the mounting blocks is abutted with the cushion block.
So set, by adjusting the thickness of cushion block so that after molding can upper and lower mould close it is tight while, sliding block with
Mounting blocks push against so that side core-pulling can accurately enter in cavity, ensure closing precision；The machining accuracy of sliding block is reduced simultaneously,
It is cost-effective.
Further setting：The Z-shaped setting of sliding block water channel, the sliding block water channel away from the shoe surface minimum range not
Less than 8 millimeters.
So set, path of the sliding block water channel of Z-type inside sliding block is longer than the runner of through type, have than through type stream
The higher cooling efficiency in road；8 millimeters of thickness limit ensures that the structural strength of sliding block is not influenced by runner；Anti- limited slip block simultaneously
Local wall thickness is excessively thin to keep its whole inhomogeneous cooling even.
Further setting：The core water channel and the cooling hole are not less than 10 millis away from side core-pulling surface minimum range
Rice.
So set, 10 millimeters of thickness limitation ensures that the structure structural strength of side core-pulling is not influenced by runner；Simultaneously
Prevent side core-pulling local wall thickness is excessively thin from keeping its whole inhomogeneous cooling even and micro deformation occurs, to influence mold actions and production
Quality.
In conclusion the invention has the advantages that：
1. side core-pulling cools down Quick uniform, high with sliding block and mounting blocks cooperation precision, to improve product quality；
2. sliding block cools down Quick uniform, with inclined guide pillar reliable in action, side is taken out into fluent movements in side core-pulling side when mold die sinking molds.
