Abstract
A kind of back-off de- mould structure, including cover half block and dynamic model block by force, between shape forming cavity.Mandril is equipped on dynamic model block.It is also equipped with back-off mold insert on dynamic model block, back-off mold insert positioning pin is equipped with below the positioning surface for being located at dynamic model block on back-off mold insert.There is movement clearance below back-off mold insert positioning pin and positioning surface.The utility model reduces sliding block in mold, the more complicated structure such as oblique top, to increase the reliability of mold to save cost.
Description
Technical field
The utility model relates to field of die equipment, especially a kind of mould structure that back-off takes off by force.
Background technique
Back-off is often had in the product of mold production, back-off is exactly the region interferenceed on product with die sinking direction,
As being buckled in fruit product, corresponding back-off processing system, way the most conventional are required when making mold
It is exactly sliding block, oblique top.But because of sliding block, ramp-roof structure is all complex, so mold one sliding block of every increase or oblique top, life
Certain increase can all be had by producing cost.
Utility model content
It is sliding in mold to reduce the purpose of the utility model is to provide a kind of mould structure that simple and reliable back-off takes off by force
Block, the more complicated structure such as oblique top, to increase the reliability of mold to save cost.
The technical solution adopted is that:
A kind of back-off de- mould structure, including cover half block and dynamic model block by force, between shape forming cavity.
Technical points are:
Mandril is equipped on dynamic model block.
It is also equipped with back-off mold insert on dynamic model block, back-off edge is equipped with below the positioning surface for being located at dynamic model block on back-off mold insert
Part positioning pin.
There is movement clearance below back-off mold insert positioning pin and positioning surface.
The advantage is that:
The utility model reduces sliding block in mold, the more complicated structure such as oblique top, to increase mold to save cost
Reliability.
Detailed description of the invention
Fig. 1 is the molding state diagram of the utility model.
Fig. 2 is ejection process figure after the die sinking of the utility model.
Fig. 3 completes figure for ejection after the die sinking of the utility model.
Cover half block 1, plastic product 2, mandril 3 are buckled to mold insert 4, and positioning surface 5 is buckled to mold insert positioning pin 6, dynamic model block 7.
Specific embodiment
A kind of back-off de- mould structure, including cover half block 1 and dynamic model block 7 by force, between shape forming cavity, type chamber has plastics production
Product 2.
Mandril 3 is equipped on dynamic model block 7.
It is also equipped with back-off mold insert 4 on dynamic model block 7, is equipped with below the positioning surface 5 for being located at dynamic model block 7 on back-off mold insert 4
It is buckled to mold insert positioning pin 6.
There is movement clearance (8mm as shown in Figure 1) below back-off mold insert positioning pin 6 and positioning surface 5.
As shown in Figure 1, cover half block 1 is controlled by injection molding machine clamping pressure and is buckled to mold insert 4 when molding, dynamic model block 7 is bonded,
And the movement clearance for having 8mm is buckled between mold insert positioning pin 6 and positioning surface 5.
When injection is completed, after die sinking, as shown in Fig. 2, cover half 1 leaves, mandril 3 starts to eject, and plastic product 2 starts to be detached from
Dynamic model 7, back-off mold insert 4 then because product back-off the reason of, can with back-off mold insert positioning pin 6 together with product to ejection direction
Movement is buckled to mold insert positioning pin 6 when ejection stroke reaches 8mm, touches positioning surface 5, is buckled to mold insert 4 by positioning surface 5
Stop motion is limited, plastic product 2 is most of at this time has been moved off moving die insert 7, there is sufficient deformation space, and mandril 3 continues
Ejection, such as Fig. 3, product leave back-off mold insert 4, complete ejection movement.Sliding block, the complex mechanisms such as oblique top are not had to reach
Come complete it is such back-off shape demoulding, reduce the cost of manufacture of mold, also save the space of mold.
