Specific embodiment
Referring to Fig.1~Fig. 2, a kind of mold of the utility model, including preceding mould, rear mold and drafting mechanism；The preceding mould packet
Mould bases 100 and front cavity 110 before including, before the front cavity 110 is mounted on mould bases 100；The rear mold include rear mould bases 200 and
Rear cavity 210；The die cavity for being used for injection molding is formed between front cavity 110 and rear cavity 210, the rear cavity 210 is provided with
Several are used to be inserted into die cavity and the mold insert 350 of the inclined hole that forms workpiece, drafting mechanism setting the preceding mould with it is described
Between rear mold and for the mold insert 350 to be deviate from from workpiece；The drafting mechanism includes take-up housing 310, several shovels
320, inclined guide pillar 340, several mold insert fixed blocks 330；The mold insert 350 can slide in the rear cavity 210, the mold insert
Fixed block 330 is fixedly connected with mold insert 350 and can slide in the rear cavity 210, the sliding road of the mold insert fixed block 330
The inclined hole of diameter and workpiece is in same straight line；The take-up housing 310 can be in the rear mould bases 200 along perpendicular to die sinking direction
Direction sliding；The shovel 320 can be slided in the rear cavity 210, and rear cavity 210 is stretched out simultaneously in one end of the shovel 320
It is clamped with the take-up housing 310, the other end is provided with oblique hook part 321, and the lower end of the mold insert fixed block 330 is provided with oblique chute
331, the oblique hook part 321 is embedded in the oblique chute 331 and can slide in the oblique chute 331；The inclined guide pillar 340 1
End is fixed in top mold holder, and the other end is inserted into the take-up housing 310 and can slide on the take-up housing 310.
When die sinking, preceding mould is far from rear mold, and since inclined guide pillar 340 is far from rear mold, inclined guide pillar 340 drives take-up housing 310 to retreat,
The shovel 320 being clamped with sliding seat is retreated with sliding seat, and makes oblique chute 331 of the oblique hook part 321 on mold insert fixed block 330
Middle sliding drives the oblique downslide of mold insert fixed block 330, and mold insert 350 is made to be detached from the inclined hole of workpiece, completes demoulding.
Since the sliding path of mold insert fixed block 330 and the inclined hole of workpiece are in same straight line, the same cunning can use
Dynamic seat drives multiple shovels 320 to exit, to drive the mold insert 350 in the inclined hole of the workpiece of multiple and different angles to deviate from, effectively
It can be realized by a core pulling driving mechanism and the mold insert 350 of multiple and different angles driven to demould.
In some embodiments wherein, the side of the rear cavity 210 is provided with that direction is vertically disposed leads with die sinking
Column 211, the take-up housing 310 are set on the guide post 211 and can slide along the guide post 211.Guide post 211 is take-up housing
310 play the guiding role, and are that the movement of take-up housing 310 is more steady.
In some embodiments wherein, the take-up housing 310 is provided with shrinkage pool 311, and the shrinkage pool 311 is arranged in rear mold
Benevolence 210 is provided with spring in the side of the rear cavity 210, the shrinkage pool 311.In molding, take-up housing 310 and rear mold
Benevolence 210 offsets, and spring is in impaction state, and when die sinking, since inclined guide pillar 340 is far from rear mold, inclined guide pillar 340 drives take-up housing
310 retreat, at this point, spring is that take-up housing 310 provides thrust, prevents sliding seat 310 mobile toward mold center direction again, guarantee
Demoulding normally completes.
As a kind of embodiment of above-described embodiment, the guide post 211 is passed through in the shrinkage pool 311, the spring (figure
In be not shown) be set on the guide post 211.Keep mould structure more succinct, reduces the volume of mold.In addition, utilizing guide post
211 can prevent spring bending, work normally spring.
In some embodiments wherein, rear mold baffle is provided between the rear cavity 210 and the rear mould bases 200
220, the rear mold baffle 220 is arranged fluted 222, and the mold insert fixed block 330 passes through the rear cavity 210 and can be inserted into institute
It states in groove 222.Oblique hook part 321 drives mold insert fixed block 330 to slide in rear cavity 210 and far from workpiece, and therefore, mold insert is solid
Determining block 330 must slide towards rear mold direction, and during sliding, mold insert fixed block 330 is inserted into groove 222, and groove 222 is
350 offer activity gap of mold insert, prevents rear mold from interfering with mold insert fixed block 330.
In some embodiments wherein, the take-up housing 310 includes the abutting part 312 before protruding into mould bases 100, described
Preceding mould bases 100 is fixed with the tight block 120 of contract, and the tight block 120 of contract offsets with the abutting part 312, the tight block 120 of contract with it is described
What abutting part 312 offseted is arranged to inclined-plane on one side.During molding, is offseted, forced with abutting part 312 using the tight block 120 of contract
Compel the tight block 120 of contract close to rear cavity 210 and make shovel 320 that mold insert fixed block 330 be driven to reset, waits injection molding next time.
In some embodiments wherein, wear-resistant block 121 is provided between the tight block 120 of the contract and the abutting part 312.
The wearability between the tight block 120 of contract and abutting part 312 is improved, the service life of mold is improved.
The above specific structure and dimension data are illustrated to the preferred embodiment of the utility model, but this reality
It is not limited to the specific embodiments with novel creation, those skilled in the art are in the premise without prejudice to the spirit of the present invention
Various equivalent deformation or replacement can be also made down, these equivalent deformations or replacement are all contained in the claim of this application and are limited
In fixed range.
