Further, the inner slide trip assembley therefor includes four inner slides, and the oblique top trip assembley therefor includes four
The oblique top core interphase distribution of a oblique top, the slider core of four inner slides and four oblique tops is at a ring.
A kind of injection mold includes die holder, caster, male template and the backing plate of sequence setting, further includes two pads
Block, ejector retainner plate, bottom plate, the mother module core and male die core that can surround injection molding cavity, the mother module core are embedded in the middle part of the caster,
The male die core is embedded in the middle part of the male template, and two cushion blocks are installed on the upside of the bottom plate, and the ejector retainner plate is set to
On the upside of the bottom plate and between two cushion blocks, the backing plate is installed on two cushion blocks, and the male template can
The relatively described backing plate flicks setpoint distance, it is characterised in that：Further include the de- back-off structure of week as claimed in claim 1 or 2, institute
It states inner slide to be slidably mounted on the male die core in inward-outward direction, the core bottom that inside contracts is fixed on the backing plate, described
Oblique guide block is installed in the male template, and the sliding shoe is fixed on the ejector retainner plate, the male die core and the male template
On be formed with and inside contract the via of core described in evacuation, evacuation is formed on the male die core, the male template and the backing plate and is tiltedly led
The via of bar.
Further, it is formed with the accommodating slider core, the oblique top core in the middle part of the male die core and described inside contracts
The through-hole of core bottom end is formed in the through-hole and is placed in the one-to-one supporting table of oblique top core, the oblique top core
In the supporting table, the inclined guide is fixedly connected across the supporting table with the oblique top core.
Further, the core that inside contracts includes core print, stem and core disk, between the core print and several slider cores
It is connected with gradient dovetail by mutually matched gradient dovetail groove obliquely, the core disk is embedded in the backing plate,
The stem is across the male die core and the male template and is removably fixed on the core print and the core disk, the core
The guide groove for avoiding the inclined guide is formed on disk.
Further, the male die core bottom is formed with one-to-one with the limit guide block and is led in inward-outward direction
To limit sliding chutes, the limit sliding chutes bottom opening closed by the male template, the limit guide block inward-outward direction sliding
In the limit sliding chutes.
Further, the male template can the relatively described backing plate structure that flicks setpoint distance be：The backing plate with it is described
It is connected by several deductions between caster, several guide pillar springs is equipped between the male template and the ejector retainner plate.
Further, inclined guide lower end inward-outward direction slides the knot that other direction stop are installed on the sliding shoe

Specific implementation mode
It is more obvious and easy to understand to enable the invention to, the specific implementation mode of the present invention is done below in conjunction with the accompanying drawings detailed
Explanation.
As shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, a kind of de- back-off structure of week, including inner slide trip assembley therefor and tiltedly
Trip assembley therefor is pushed up, the inner slide trip assembley therefor includes that several inner slides 1 and one inside contract core 2, and the oblique top trip assembley therefor includes
Several oblique tops 3 and with the one-to-one several oblique guide blocks of the oblique top 4；The inner slide includes axially extending slider core
101 and the slider core bottom is connected in the limit guide block 102 radially extended；The oblique top include oblique top core 301,
Inclined guide 302 and sliding shoe 303；Several slider cores, at a ring, are used for several oblique top core interphase distributions
Multiple back-offs of molding cylindric plastic product inner circumferential side；The core that inside contracts is installed in the ring, if it is described inside contract core with
It is connected with gradient dovetail 6 by mutually matched gradient dovetail groove 5 obliquely between the dry slider core, it is described interior
Contracting core bottom is fixed on the backing plate of injection mold；Oblique guide hole 401, and the oblique guide block installation are formed in the middle part of the oblique guide block
In in the male template of injection mold, the sliding shoe is fixed on the ejector retainner plate of injection mold, the inclined guide upper end with it is described
Oblique top core is fixedly connected, and is arranged in the oblique guide hole in the middle part of the inclined guide, the sliding of inclined guide lower end inward-outward direction
Other direction stop are installed on the sliding shoe.
In above structure, a ring is surrounded by the slider core of several inner slides and the oblique top core of several oblique tops, it can
The axially extending multiple back-offs in full side to be molded plastic product, for example, close to 100 bottom of plastic product shown in Fig. 1
The annular back-off 1001 of opening inner circumferential side, the back-off 1002 close to 100 top inner circumferential side of plastic product and top, by inside contracting
The cooperation of the gradient dovetail groove and gradient dovetail that are arranged between core and slider core, several cunnings can be driven by inside contracting core axial movement
Block core inside contracts simultaneously, to realize that several slider cores first inside contract the function of de- back-off, passes through inclined guide and oblique guide block and cunning
The cooperation of motion block inside contracts the de- function being buckled to, the final week for realizing cylindric plastic product after realizing driving oblique top core
Inside contract de- back-off, and inside contract core, slider core and oblique top core axially longer, it is longer to solve back-off depth, oblique top without
The problem of method demoulds.
The operation principle of the de- back-off structure of week of the invention is：
In die sinking, male template first flicks a distance with respect to backing plate to Z-direction (die sinking direction), and ejector retainner plate follows male model
