Description
Technical field
The utility model is related to plastic mould injection-moulding device fields more particularly to a kind of carry to be buckled to circular ring demoulding auxiliary device
Mold.
Background technology
Oblique top is the mechanism for being used for being buckled to inside formed product in mold design, is suitable for fairly simple back-off situation.
Existing oblique top is often excessive because of oblique top glue position, and product is caused to glue oblique top, is obstructed in Double-ejection, leads to deformation of products, shadow
Product quality is rung, and cannot automatically be demoulded, production efficiency is influenced.Currently, general similar highly difficult product, will prevent from producing
Product glue oblique top, realize safety and stability production, need to do many labyrinths on mold, occupy very big die space, and have very
Big limitation, if production is not sufficiently stable, mould structure is complicated, and manufacturing cost is high, competitiveless etc..
Invention content
Utility model aims to solve viscous oblique top is easy when product is buckled to depanning, one kind is provided and carries
The mold of circular ring demoulding auxiliary device is detained, which can help product to be detached from oblique top, avoid product in Double-ejection by La Baila
It is rotten.
It is provided by the utility model with back-off circular ring demoulding auxiliary device mold include mold core and back-off circular ring demoulding auxiliary device,
Back-off circular ring demoulding auxiliary device is installed on the outside of mold core and is in contact with mold core.
It includes oblique top and mechanical elastic block to be buckled to circular ring demoulding auxiliary device, and one end that oblique top is in contact with product is provided with for pacifying
The through-hole of mechanical elastic block is filled, mechanical elastic block can slide in through-hole along through-hole central axis direction, the two sides of mechanical elastic block outwardly point
Not Wei product contact surface and core contact face, the one side that core contact face, mold core are in contact with core contact face is each parallel to opening
Mould direction.
Preferably, back-off circular ring demoulding auxiliary device further includes limited block, and limited block is for preventing mechanical elastic block to be detached from through-hole.
Preferably, limited block is provided with fixing end and baffle end, and fixing end is fixed in oblique top, and baffle end is to mechanical elastic block
Direction extends.
Preferably, through-hole and mechanical elastic block are in I-shaped.
The beneficial effects of the utility model are：
1, through-hole installation machinery is arranged in the mold provided by the utility model with back-off circular ring demoulding auxiliary device in oblique top
Bullet block, the product contact surface of mechanical elastic block withstand the edge of product back-off, and mold core is withstood in core contact face, and oblique top is in ejecting product
During push mechanical elastic block simultaneously, but since core contact face, mold core and the core contact face one side being in contact are parallel
In die sinking direction, mold core blocks mechanical elastic block, therefore the direction of motion of mechanical elastic block will not favour die sinking as oblique top
Direction, and can only be moved along the direction for being parallel to die sinking direction, so that product also can only mold direction along being parallel to
Direction movement, since there are certain angles for the moving direction and the moving direction of oblique top of product, in product by lifter ejection
During, oblique top can be progressively disengaged at the back-off of product.
2, since mechanical elastic block is installed in the through-hole of oblique top, occupied space is few, the volume of mold is not will increase, without changing
Modeling has the structure of other mechanisms, strong applicability.
3, through-hole and mechanical elastic block are in I-shaped, and simple in structure, manufacturing cost is low, and I-shaped structure is equivalent to as machinery
The sliding of bullet block provides track, increases stability.
4, in actual operation, depanning direction is generally parallel to horizontal direction, after lifter ejection certain distance, mechanical elastic
It can fall off from through-hole because support is lost below block, setting limited block can fall off to avoid mechanical elastic block from through-hole, protect
Demonstrate,prove mold normal operation.

Specific implementation mode
The utility model is described further below in conjunction with attached drawing, the embodiment being exemplified below only represents a kind of or several
Kind preferred forms, should not constitute limitations of the present invention.
As shown in Figure 1, the mold provided by the utility model with back-off circular ring demoulding auxiliary device includes that mold core 1 and back-off are de-
Mould auxiliary device 2, back-off circular ring demoulding auxiliary device 2 are installed on the outside of mold core 1 and are in contact with mold core 1.
As shown in Figures 2 and 3, back-off circular ring demoulding auxiliary device 2 includes oblique top 21 and mechanical elastic block 22, oblique top 21 and product 3
The one end being in contact is provided with the through-hole 211 for installing mechanical elastic block 22, and mechanical elastic block 22 can be in through-hole along through-hole 211
Mandrel direction is slided, and the two sides of mechanical elastic block 22 outwardly is respectively product contact surface 221 and core contact face 222, core contact
The one side that face 222, mold core 1 are in contact with core contact face 222 is each parallel to die sinking direction.
In addition, back-off circular ring demoulding auxiliary device 2 further includes limited block 23, limited block 23 is logical for preventing mechanical elastic block 22 to be detached from
Hole 211.Limited block 23 is provided with fixing end and baffle end, and fixing end is fixed in oblique top 21, and baffle end is to 22 side of mechanical elastic block
To extension.
Preferably, through-hole 211 and mechanical elastic block 22 are in I-shaped.
From fig. 4, it can be seen that during product is by lifter ejection, oblique top can be progressively disengaged at the back-off of product.
Finally it should be noted that above example is only to illustrate the technical solution of the utility model rather than to this practicality
The limitation of novel protected range, although being explained in detail to the utility model with reference to preferred embodiment, the common skill of this field
