Description

Simple line position secondary core-pulling mechanism
Technical field
The utility model relates to injection mold more particularly to a kind of simple line position secondary core-pulling mechanisms.
Background technique
Injection mold is that forming plastic product often uses mold, by the plasthetics of injection mold energy shaped form multiplicity with Meet people's demand, some plasthetics need to open up the structures such as hole and slot or screw column in side wall, and corresponding plastic mould is then It needs to do slide structure and completes core pulling, core pulling is carried out to side by die sinking power.Since plastic cement products form, under molten condition Trapped gas, sticking to mould are easy when filling, the adhesive force of plasthetics can be such that product damage breaks in line position core pulling action, can not produce Qualified products out.
Utility model content
In view of the drawbacks of the prior art, the purpose of the utility model is to provide a kind of simple line position secondary core-pulling mechanisms.
To achieve the above object, the utility model uses following technical scheme:
A kind of simple line position secondary core-pulling mechanism, including shovel, inclined guide pillar, line position seat, briquetting, slide insert, activity edge Part, pin and position-limitting pin, inclined guide pillar are sequentially inserted into from top to bottom in the slanting guide pillar hole of shovel, line position seat and movable insert, row One end of position mold insert is extend into line position seat, and movable insert is interspersed in line position seat, and pin one end is fixedly connected with movable insert, The other end is inserted into the product in slide insert, and position-limitting pin passes through the limit hole of movable insert and both ends fixation is expert at In the seat of position, slanting guide pillar hole is U-shaped empty avoiding on line position seat.
In a preferred technical solution, the two sides of the line position seat are equipped with shoulder, and the briquetting is set on shoulder simultaneously Push down the two sides of line position seat.
The utility model has the beneficial effects that not only having solved the problems, such as product trapped gas but also having solved product considerable sticking problems, system is improved Product qualification rate;Structure is simple, easy to make, high production efficiency.
Detailed description of the invention
Fig. 1 is a kind of simple line position secondary core-pulling mechanism explosive view according to the preferred embodiment in the utility model.
Fig. 2 is the area Tu1Zhong A enlarged drawing.
Fig. 3 is to mold state solid according to a kind of simple line position secondary core-pulling mechanism of the preferred embodiment in the utility model Figure.
Fig. 4 is according to a kind of inclined guide pillar of simple line position secondary core-pulling mechanism of the preferred embodiment in the utility model, line position Seat, briquetting, slide insert, movable insert, pin and position-limitting pin installation diagram.
Fig. 5 is to be inlayed according to a kind of briquetting of simple line position secondary core-pulling mechanism of the preferred embodiment in the utility model, line position Part, movable insert, pin and position-limitting pin installation diagram.
Specific embodiment
The utility model is described in further detail in conjunction with attached drawing by the following examples.
With reference to Fig. 1-Fig. 5, a kind of simple line position secondary core-pulling mechanism, including shovel 1, inclined guide pillar 2, line position seat 7, briquetting 5, Slide insert 4, movable insert 3, pin 8 and position-limitting pin 6, inclined guide pillar 2 are sequentially inserted into shovel 1, line position seat 7 from top to bottom and live In the slanting guide pillar hole of dynamic mold insert 4, one end of slide insert 4 is extend into line position seat 7, and movable insert 3 is interspersed in line position seat 7, 8 one end of pin is fixedly connected with movable insert 3, and 8 other end of pin is inserted into the product 10 in slide insert, spacer pin Nail 6 passes through the limit hole 31 of movable insert and both ends are fixed in line position seat, and slanting guide pillar hole is U-shaped empty avoiding on line position seat.Limit Hole 31 needs to be equipped with certain length according to product, and position-limitting pin 6 is in one end of limit hole 31 when molding.
Die sinking process are as follows: motive power is obtained by injection moulding machine mould open, and in the process of die sinking, the movable insert 3 in mechanism exists 8 core pulling of pin is carried out under the drive of inclined guide pillar 2, since slanting guide pillar hole is U-shaped empty avoiding, line position seat 7 and slide insert on line position seat 7 4 remain stationary.When 3 core pulling of movable insert reaches position-limitting pin 6, pin 8 is fully drawn out at this time, just at this moment inclined guide pillar 2 The U-shaped position for reaching line position seat drives behavior seat 7 and the completion of slide insert 4 to have suffered simple line position twice core pulling movement.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined Assert that the specific implementation of the utility model is only limited to these instructions.
