Abstract

The utility model provides a circular-arch core-pulling mechanism for an injection mould. The circular-arch core-pulling mechanism comprises a circular-arch-shaped mould core, wherein a circular-arch-shaped circular-arch slide block is arranged at the rear end of the circular-arch-shaped mould core; the circular-arch slide block and the circular-arch-shaped mould core are located on the same circumference; tooth profiles are arranged on the inner side of the circular-arch slide block; the inner side of the circular-arch slide block is further provided with a driving gear engaged with the tooth profiles; the driving gear is driven by a rack; the rack is connected with a driving device for driving the rack to move. According to the circular-arch core-pulling mechanism for the injection mould, power is transmitted to the circular-arch slide block by the rack, the gear and a transmission shaft so as to effectively reduce the occupied space of the circular-arch core-pulling structure. The rack, the gear and the circular-arch slide block are in mutual engagement between the gears to realize the stable transmission of power and ensure the stability and the reliability of circular-arch core-pulling movements.

Description

Technical field
The utility model relates to a kind of arc core-pulling mechanism of injection mold.
Background technology
High-end automobile external door handle is circular shape, in the middle of handle, is that circular arc is hollow.The mold cores of this product of moulding must be also circular shape, and after injection mo(u)lding completes, how circular arc core being detached to product is technological difficulties.At present, arc core-pulling injection mold is mainly to complete arc core-pulling action with linkage.Complicated institute of connecting rod knot mechanism takes up space large, especially when designing multi-point mould for enhancing productivity, uses linkage, die size will be forced to amplify, and meanwhile mold materials drops into raising and need use more large-tonnage injection machine, causes the wasting of resources.
Summary of the invention
In order to overcome the deficiency of the arc core-pulling mechanism of existing injection mold, the utility model provides the arc core-pulling mechanism of the injection mold of a kind of compact conformation, reliable in action.
The technical scheme in the invention for solving the technical problem is: a kind of arc core-pulling mechanism of injection mold, comprise for circular arc core, the rear end of described circular arc core is provided with the circular arc slide block of a circular arc, and described circular arc slide block and described circular arc core are positioned on same circumference;
The inner side of described circular arc slide block is provided with profile of tooth, the inner side of described circular arc slide block also have one with the driven wheel of described profile of tooth engagement, described driven wheel is subject to a rack drives, described tooth bar with one for driving its drive unit moving to be connected.
Further, there is bottom gears the below of described driven wheel, described bottom gears and the engagement of described tooth bar, between the center of described bottom gears and the center of described driven wheel, by power transmission shaft, be connected in series, between described power transmission shaft and described bottom gears, be supported with bearing between power transmission shaft and described driven wheel.
Further, described circular arc core, circular arc slide block, driven wheel, power transmission shaft, bottom gears form the assembly of loosing core, and the described assembly of loosing core has two covers, lays respectively at the both sides of described tooth bar, and mesh with two bottom gears respectively the both sides of described tooth bar.
Further, the outside of described circular arc slide block is also provided with retaining oil cylinder, and the piston rod of described retaining oil cylinder is provided with retaining mold insert, and described circular arc slide block is provided with the edge hole with described retaining mold insert adaptation.
The utility model also has following additional technical feature:
Described circular arc slide block is covered with guide cover.
Described drive unit is to drive oil cylinder.
After injection mo(u)lding completes, retaining oil cylinder resets and drives retaining mold insert to detach the locking of circular arc slide block releasing to circular arc slide block.Then drive cylinder ejector band carry-over bar to push ahead, the bottom gears of rack drives and its engagement, bottom gears drives driven wheel by power transmission shaft, driven wheel drives with the circular arc slide block of its engagement in rotary moving again, circular arc slide block and product are departed from, and then die sinking ejecting product, thereby reset and to make whole arc core-pulling mechanism return with rear drive oil cylinder, and then matched moulds, follow retaining cylinder ejector, retaining mold insert is embedded in edge hole, circular arc slide block is locked, the production that next enters next mould product.
The beneficial effects of the utility model are: by tooth bar, gear and power transmission shaft, power is reached to circular arc slide block, effectively reduced arc core pulling structure and taken up space.Tooth bar, gear, circular arc slide block are intermeshing between gear, realize the transmission stably of power, have guaranteed the reliable and stable of arc core-pulling action.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is top view of the present utility model.
Fig. 3 is retaining oil cylinder and the schematic diagram that coordinates of circular arc slide block.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, a kind of arc core-pulling mechanism of injection mold, comprises for circular arc core 1, the rear end of described circular arc core 1 is provided with the circular arc slide block 2 of a circular arc, and described circular arc slide block 2 is positioned on same circumference with described circular arc core 1.In the present embodiment, described circular arc slide block 2 is covered with guide cover, can play the effect of guiding and protection.
The inner side of described circular arc slide block 2 is provided with profile of tooth 3, the inner side of described circular arc slide block 2 also have one with the driven wheel 4 of described profile of tooth 3 engagements, described driven wheel 4 is driven by a tooth bar 5, described tooth bar 5 with one for driving its drive unit moving to be connected.In the present embodiment, described drive unit is to drive oil cylinder 6, there is bottom gears 7 below of described driven wheel 4, described bottom gears 7 and 5 engagements of described tooth bar, between the center of described bottom gears 7 and the center of described driven wheel 4, by power transmission shaft 8, be connected in series, between described power transmission shaft 8 and described bottom gears 7, be supported with bearing 9 between power transmission shaft 8 and described driven wheel 4.
Driving oil cylinder 6 to eject band carry-over bar 5 pushes ahead, tooth bar 5 drives the bottom gears 7 with its engagement, bottom gears 7 drives driven wheel 4 by power transmission shaft 8, driven wheel 4 drives with the circular arc slide block 2 of its engagement in rotary moving again, circular arc slide block 2 and product 10 are departed from, and then die sinking ejecting product 10, thereby reset and make whole arc core-pulling mechanism return with rear drive oil cylinder 6, and then matched moulds, the production that next enters next mould product.
