Description
Technical field
A kind of injection mold is the utility model is related to, more particularly to a kind of core pulling of injection mold allows bit architecture.
Background technology
As shown in figure, a kind of plastic cement tubular products 1, the inside of product 1 have at two to the back-off structure 11 of pipe sunken inside,
When producing this product 1 using injection mold, prior art is to lead to producing this tubular products 1 with back-off structure 11
It can often use slide structure, be pulled out inside tubular products line position using the deformation effect of plastic cement during die sinking, forced demoulding,
Because back-off structure 11 is without the space of deformation during this, line position deviates to be easy to by force to draw bad draw to deform the inside of product 1,
The precision of product 1 cannot ensure that mold component is easily damaged, it is necessary to often change in addition, and the maintenance cost of mould is high.
Utility model content
The purpose of this utility model, which is to provide a kind of core pulling of injection mold, allows bit architecture.
To achieve these goals, the utility model provides following technical scheme：
A kind of core pulling of injection mold allows bit architecture, including A plates, front cavity, rear cavity, the B set gradually from top to bottom
Plate and de- plate, the front cavity are fixedly connected with A plates, and the rear cavity is fixedly connected with B plates, and the side of the rear cavity is provided with
Line position, the line position includes shaping axle and movable block, between the shaping axle insertion front cavity and rear cavity, the front cavity,
Rear cavity and shaping axle surround die cavity, and the shaping axle exits die cavity with the movable block during die sinking, it is characterised in that：It is described de-
There is the core pulling mold insert that is vertically arranged, the lower end of the core pulling mold insert is fixedly connected with de- plate during matched moulds, and upper end has arc on plate
Shape is raised and is abutted with die cavity；Spring is gone back between the de- plate and B plates, nylon plug is provided between the A plates and B plates.
Further, the B plates are provided with mounting groove, are provided with limited screw in the mounting groove, under the limited screw
End is fixedly connected with de- plate, bottom land of the upper end of limited screw higher than mounting groove during matched moulds.
Further, the core pulling mold insert is provided with two side by side.
The beneficial effects of the utility model are：During die sinking, because the effect A plates and B plates of nylon plug will not separate first
Die sinking, de- plate mold first with B plates under the action of the spring, and core pulling mold insert moves downward with de- plate, leaves die cavity, subsequent A
Plate and the die sinking of B plates, line position is deviate from out of product pipe, because the back-off structure of product has the sky of deformation during pull-out
Between, line position will not draw bad product or be in the presence of stuck when deviating from, not only ensure that the quality of product, also reduce mould more
Change the cost of maintenance.
Brief description of the drawings
Fig. 1 is the structural scheme of mechanism of tubular products；
Fig. 2 is overall structure diagram of the present utility model；
Fig. 3 is the structural scheme of mechanism molded between de- plate and B plates of the present utility model；
Fig. 4 is of the present utility model.
Embodiment
The utility model is further described below in conjunction with accompanying drawing：
A kind of core pulling of injection mold as shown in Fig. 1 to Fig. 4 allows bit architecture, including the A plates set gradually from top to bottom
2nd, front cavity 3, rear cavity 4, B plates 5 and de- plate 6, the front cavity 3 are fixedly connected with A plates 2, and the rear cavity 4 fixes 5 with B plates
Connection, the side of the rear cavity 4 are provided with line position 7, and the line position 7 includes shaping axle 71 and movable block 72, the shaping axle 71
Insert between front cavity 3 and rear cavity 4, the front cavity 3, rear cavity 4 and shaping axle 71 surround die cavity 8, during die sinking it is described into
Profile shaft 71 exits die cavity 8 with the movable block 7, has the core pulling mold insert 61 being vertically arranged on the de- plate 6, is taken out described in during matched moulds
The lower end of core mold insert 61 is fixedly connected with de- plate, and upper end has arc convex and abutted with die cavity 8；The de- plate 6 and B plates 5 it
Between go back spring 62, nylon plug 21 is provided between the A plates 2 and B plates 5.
In the present embodiment, the B plates 5 are provided with mounting groove 51, and limited screw 52 is provided with the mounting groove 51, described spacing
The lower end of screw 52 is fixedly connected with de- plate 6, and the upper end of limited screw 52 is higher than the bottom land of the mounting groove 51 during matched moulds.
In the present embodiment, the core pulling mold insert 61 is provided with two side by side.
During die sinking, because the effect A plates 2 and B plates 5 of nylon plug 21 will not separate die sinking first, plate 6 is taken off in spring 62
Effect is lower to be molded first with B plates 5, and core pulling mold insert 61 moves downward with de- plate 6, leaves die cavity, and subsequent A plates 2 and B plates 5 mold,
The lateral movement to the left of movable block 71 of line position 7 deviates from shaping axle 72 out of product 1 pipe, due to product 1 during pull-out
Back-off structure 11 have the space of deformation, line position 7 will not draw bad product 1 or stuck situation occur, not only ensure when deviating from
The quality of product 1, also reduce the cost of die change maintenance.
It is described above that not technical scope of the present utility model is imposed any restrictions, it is all according to the utility model technical spirit
Any modification, equivalent variations and the modification that embodiment to more than is made, still fall within the model of the technical solution of the utility model
In enclosing.
