Description
Technical field
Technical field of mold is the utility model is related to, more particularly to a kind of injection mould for being applied to back-off class formed product
Demolding structure.
Background technology
When part is manufactured with mould, this product of the circle back-off of pillar class one is run into, what is normally occurred is
Back-off is solved with two oblique tops, but so not only unusual cost of idleness in fact, and have product be sticked to it is bad in oblique top
The phenomenon of the demoulding, it is therefore desirable to optimize the demolding structure that product has pillar class to be buckled to.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of injection mould for being applied to back-off class formed product and takes off
Mode structure, have reduce die manufacturing cost, improve production efficiency, it is stable the features such as.
Technical solution is used by the utility model solves its technical problem：There is provided it is a kind of be applied to back-off class product into
The injection mould demolding structure of type, including insert, rear mold shortening and activity pallet, the insert are embedded in rear cavity, the edge
Block makes the shape of product back-off, and the rear mold shortening sequentially passes through activity pallet and rear pattern plate and coordinates with insert from bottom to up,
The rear mold shortening lower end is designed with limiting section, and the limiting section lower end fitting is disposed with briquetting, and the briquetting is consolidated by screw
The bottom of activity pallet is scheduled on, the activity pallet is movably connected by limited screw and rear pattern plate, the spacing spiral shell
The spring that silk is withstood through upper end with rear pattern plate.
Supplemented as one kind to technical solution described in the utility model, the limited screw lower end is designed with spacing
Round platform, is to ensure that run action is reliable and stable.
Supplemented as one kind to technical solution described in the utility model, the activity pallet lower face and spacing circle
The concentric position of platform is provided with groove.
Supplemented as one kind to technical solution described in the utility model, the diameter of the groove is more than limit round table
Diameter, and limit round table can move up and down in a groove.
Beneficial effect：A kind of injection mould demolding structure for being applied to back-off class formed product is the utility model is related to, is passed through
By the insert being embedded in mode make product back-off shape replace two oblique tops of regular situation design, it is this by taking
The frame mode that rear mold inside contracts, can complete product stripping, the utility model, which has, reduces mould completely without design oblique top
Manufacture cost, improve production efficiency, it is stable the features such as.

Embodiment
With reference to specific embodiment, the utility model is expanded on further.It is to be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
Please the appended claims limited range.
The embodiment of the utility model is related to a kind of injection mould demolding structure for being applied to back-off class formed product, such as schemes
Shown in 1, including insert 1, rear mold shortening 2 and activity pallet 8, the insert 1 are embedded in rear cavity 9, and the insert 1 is made
The shape of product back-off 10, the rear mold shortening 2 sequentially pass through activity pallet 8 and rear pattern plate 7 and coordinate with insert 1 from bottom to up,
2 lower end of rear mold shortening is designed with limiting section 11, and 11 lower end of the limiting section fitting is disposed with briquetting 3, and the briquetting 3 passes through
Screw 4 is fixed on the bottom of activity pallet 8, and the activity pallet 8 is movably connected by limited screw 5 and rear pattern plate 7,
The spring 6 that the limited screw 5 is withstood through upper end with rear pattern plate 7.
5 lower end of limited screw is designed with limit round table 13.
8 lower face of activity pallet is provided with groove 12 with the concentric position of limit round table 13.
The diameter of the groove 12 be more than limit round table 13 diameter, and limit round table 13 can be in groove 12 on
Lower movement.
Embodiment
During die sinking, when current template is separated with rear pattern plate 7, the spring 6 under compressive state can drive work
Dynamic supporting plate 8 is walked downwards, while activity pallet 8 drives rear mold shortening 2 to depart from product, then can complete product using ejecting mechanism
The demoulding, the utility model have reduce die manufacturing cost, improve production efficiency, it is stable the features such as.
