Description
Technical field
The utility model is related to injection mold technology more particularly to a kind of demolding structures applied to the injection molding of card frame.
Background technology
Application of the card frame in mobile phone is most commonly used, therefore the injection molding of card frame produces also than wide, but is noted in card frame
After being moulded into type, often due to demoulding when die sinking is unreasonable, interior grip force is excessive when ejection causes the deformation of card frame, and produces
Defective products reduces production efficiency, improves production cost.
Utility model content
The purpose of this utility model is that providing a kind of demoulding applied to the injection molding of card frame in view of the deficiencies of the prior art
Structure, the demolding structure that should be applied to the injection molding of card frame is novel in design, simple in structure, solves card frame deformation of the card frame in die sinking
Problem reduces production cost.
In order to achieve the above objectives, the utility model is achieved through the following technical solutions.
A kind of demolding structure applied to the injection molding of card frame includes the rear pattern plate of front template and Corresponding matching, front template with
Product shape chamber is provided between rear pattern plate, front template upper end is installed with upper mounted plate, and rear pattern plate lower end is installed with bottom plate, and
Bottom plate upper end is provided with the spring flicked with rear pattern plate, and product cavity lower end is connected in the rear mold mold insert being vertically arranged,
Thimble is installed in rear mold mold insert, thimble is installed in ejector retainner plate upper end with rear mold mold insert lower end, and ejector retainner plate is fixedly installed in lower solid
Fixed board upper end.
Wherein, it is installed with runner plate between fixed plate and the front template.
Wherein, fixed plate upper end is installed with sprue bushing.
Wherein, the ejector retainner plate upper end is installed with the rear mold backing plate for being fixed on the rear pattern plate upper end.
The beneficial effects of the utility model are：A kind of demolding structure applied to the injection molding of card frame described in the utility model,
Include the rear pattern plate of front template and Corresponding matching, product shape chamber, front template upper end dress are provided between front template and rear pattern plate
Equipped with upper mounted plate, rear pattern plate lower end is installed with bottom plate, and bottom plate upper end is provided with the spring flicked with rear pattern plate,
Product cavity lower end is connected in the rear mold mold insert that is vertically arranged, is installed with thimble in rear mold mold insert, thimble under rear mold mold insert
End is installed in ejector retainner plate upper end, and ejector retainner plate is fixedly installed in bottom plate upper end.The utility model, will by spring in die sinking
Bottom plate is flicked with rear pattern plate, and rear mold mold insert is made first to be detached with product cavity, to make product before not ejecting just
It is detached with rear mold mold insert, solves the problems, such as that product card frame caused by viscous force is excessive deforms, reduce the product of product fraction defective；
Therefore the utility model has novel in design, simple in structure, solves card frame problem on deformation of the card frame in die sinking, reduces production
The advantages of cost.
Description of the drawings
The utility model is further detailed below with attached drawing, but the embodiment in attached drawing is not constituted pair
Any restrictions of the utility model.
Fig. 1 is the structural schematic diagram of the utility model.
Include in Fig. 1：

Specific implementation mode
The utility model is illustrated with reference to specific embodiment.
As shown in Figure 1, a kind of demolding structure applied to the injection molding of card frame
A kind of demolding structure applied to the injection molding of card frame includes the rear pattern plate 2 of front template 1 and Corresponding matching, front template 1
Product shape chamber 3 is provided between rear pattern plate 2,1 upper end of front template is installed with upper mounted plate 11, and 2 lower end of rear pattern plate is installed with down
Fixed plate 21, and 21 upper end of bottom plate is provided with the spring 22 flicked with rear pattern plate 2,3 lower end of product cavity is connected in perpendicular
To the rear mold mold insert 23 of arrangement, thimble 24 is installed in rear mold mold insert 23, thimble 24 is installed in thimble with 23 lower end of rear mold mold insert
25 upper end of plate, ejector retainner plate 25 are fixedly installed in 21 upper end of bottom plate.
Further, runner plate 12 is installed between fixed plate 11 and the front template 1.
Further, 11 upper end of fixed plate is installed with sprue bushing 13.
Further, 25 upper end of the ejector retainner plate is installed with the rear mold backing plate 26 for being fixed on 2 upper end of the rear pattern plate.
It need to further explain, the utility model is in die sinking, by spring 22 by bottom plate 21 and 2 bullet of rear pattern plate
It opens, so that rear mold mold insert 23 is first detached with product cavity 3, to make product just divide with rear mold mold insert 23 before not ejecting
From, solve the problems, such as product caused by viscous force is excessive card frame deform, reduce the product of product fraction defective；Therefore the utility model
With novel in design, simple in structure, the advantages of solving card frame problem on deformation of the card frame in die sinking, reduce production cost.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
Limitations of the present invention.
