Description
Technical field
The present invention relates to injection mold, in particular to a kind of line position relocation mechanism.
Background technique
Injection mold is made of dynamic model and cover half two parts, and dynamic model is mounted on the moving die plate of injection (mo(u)lding) machine, cover half
It is mounted on the fixed form of injection (mo(u)lding) machine, in injection moulding, dynamic model and cover half closure constitute running gate system and type chamber, open
Dynamic model and cover half separation are when mould to take out plastic products.
When the inner wall of injecting products has back-off, buckle and boss etc. with semi-closed groove or through-hole groove, outer wall
When structure, product is ejected by thimble when general outer wall construction is separated with rear model core outward, however passes through thimble for product
When pushing up outward, product surface is easy whitening, has trace at thimble, improves the fraction defective of product；If product structure is more multiple
It is miscellaneous, product can not be ejected by thimble；And the semi-closed groove or through-hole groove structure of injecting products cannot be directly from moulds
Directly deviate from tool, needs to complete injection molding and the knockout course of injecting products by core-pulling mechanism.
And when being directed to product currently on the market with long pore structure, when designing long punch die, usually core-pulling mechanism is set
In the side of mold, then controlling moving core movement by oil cylinder separates it with product, when product band is gradient, core pulling
The moving core of structure must be completely disengaged with product could take out product, then the stroke of pulled core structure will increase, and
The length of oil cylinder more lengthens, and when the die length of design is longer, needs just complete product using relatively large forming machine
Production.Regardless of for large enterprise or small business, large-scale forming machine does not only take up the space of workshop
Area reduces workshop space utilization rate, largely increases cost burden, and produce product usually to put it is more
For platform forming machine to meet production requirement, large-scale forming machine is unable to satisfy the demand of putting, to be unable to meet production demand.More
Further, large-scale forming machine is not easy to worker operation, and safeguards highly inconvenient.Therefore, it is necessary to design a kind of row
Position relocation mechanism, to solve the above technical problems.
Summary of the invention
In view of the deficiencies of the prior art, the purpose of the present invention is to provide a kind of line position relocation mechanism, pass through ejector retainner plate control
Product stripping is completed in the movement of core-pulling mechanism processed and the core pulling campaign of core-pulling mechanism, cooperation, is reduced die length, is suitable for
Different types of forming machine, meets different production requirements, reduces the manufacturing cost of production cost and mold accordingly.
The technical scheme adopted by the invention is as follows:
A kind of line position relocation mechanism, including preceding mould and rear mold are equipped with preceding model cavity in the side of preceding mould face rear mold, rear
Mould is equipped with the rear model core cooperated with preceding model cavity, fixing groove is equipped with close to the side of rear model core in rear mold, in fixing groove
It is equipped with the core-pulling mechanism of achievable die cavity core pulling, is equipped in the lower part of core-pulling mechanism by core-pulling mechanism mould direction promotion forward
Pushing device.
Preferably, the core-pulling mechanism includes fixing seat, the fixing seat is equipped with limiting slot, is equipped on limiting slot
Sliding rail is equipped with core pulling slide on the slide rail, is equipped with oil cylinder far from the side of rear model core in fixing seat, the piston of the oil cylinder pushes away
Bar is fixedly connected with one end of core pulling slide, and the other end of the core pulling slide is connected with the core pulling matched with product, described
Core pulling sliding sleeve is equipped between core pulling and fixing seat, the core pulling is slidably connected with core pulling sliding sleeve.
Preferably, the pushing device includes ejector retainner plate, at least one push rod component, institute are equipped on the top of ejector retainner plate
The one end for stating push rod component is fixedly connected with ejector retainner plate, and the other end of the push rod component is fixedly connected with fixing seat.
Preferably, the push rod component includes mandril there are two the push rod component, in mandril close to the one of fixing seat
End is equipped with fixation hole, and the fixation hole is connect by bolt with fixing seat, and mandril sliding sleeve, the mandril sliding sleeve are equipped in rear mold
It is slidably connected with mandril.
The beneficial effects of the present invention are:
(1) product outer wall has the structures such as back-off, buckle and boss, directly passes through pushing device for core-pulling mechanism with production
Mould direction ejects product forward, completes product and separates with rear model core, optimizes product ejecting structure, and solve in the prior art
Surface whitening when product ejects has the technical problems such as trace, meanwhile, it is capable to which it is complicated and can not pass through top to solve product outer wall construction
The problem of needle ejects；
(2) core pulling of core-pulling mechanism under the drive of oil cylinder toward oil cylinder direction move, when core pulling move to product internal diameter compared with
When big position, mould direction ejects pushing device of the invention forward by core-pulling mechanism, and product Automatic-falling or can manually take
Out, compared with the prior art, when product core pulling, product stripping is can be completed without being kept completely separate with product in core pulling, largely
The movement travel of core-pulling mechanism is reduced, die length is reduced, product can be produced using relatively small forming machine, improved
The space utilization rate of enterprise's workshop reduces the manufacturing cost of production cost and mold accordingly, moreover, being suitable for smaller
Forming machine be easier to the maintenance to mold, maintenance cost is low；
(3) there are two push rod component for present invention setting, reinforce the support force of core-pulling mechanism, improve the stabilization of core-pulling mechanism
Property.
