Deformation is expanded, influences the product quality processed.
Utility model content
The purpose of this utility model is to overcome above-mentioned technical deficiency, the proposition wallboard extrusion that inserted type is fixed a kind of up and down
Mould, the side wall for solving the larger face of extrusion die in the prior art easily expand the technical problem of deformation.
To reach above-mentioned technical purpose, the technical solution of the utility model provides the wallboard that inserted type is fixed a kind of up and down and squeezed
Go out mould, including be fixedly connected sequentially from the bottom to top die body, rebound, supporting plate, mouth mold；The rebound is close by two pieces
The splice plate of contact is formed, and the one side that two pieces of splice plates contact with each other is equipped with a groove, and two grooves surround to form one
The die cavity that cross-sectional area gradually increases from the bottom to top；The upper and lower end of the rebound is respectively arranged with second boss, first convex
Platform, the upper surface of the die body set one first clamping groove, and the first boss, which coordinates, is built in the first clamping groove, described
Supporting plate lower surface sets one second clamping groove, and the second boss, which coordinates, is built in the second clamping groove.
Compared with prior art, the beneficial effects of the utility model include：The upper and lower end of the rebound of the extrusion die point
Second boss, first boss are not provided with, and second boss, first boss are respectively cooperating with being built in the second clamping groove, the first card
Tight groove, when rebound expands deformation, the first clamping groove, the second clamping groove can play about to the both ends of rebound
Shu Zuoyong, limit the dilatancy of rebound.
Brief description of the drawings
Fig. 1 is schematic elevation view of the present utility model.
The right side that Fig. 2 is Fig. 1 regards schematic diagram.
Fig. 3 is schematic cross-sectional views of the Fig. 2 along B-B.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
Refer to Fig. 1~3, the present embodiment provides a kind of wallboard extrusion die that inserted type is fixed up and down, including by it is lower extremely
On be fixedly connected sequentially die body 1, rebound 2, supporting plate 3, mouth mold 4.
Die body 1, the lower surface of the die body 1 set a charging aperture 11, and the upper surface of die body 1 sets one first clamping groove
12。
Rebound 2, the rebound 2 are made up of the splice plate 21 of two pieces of close contacts, and two splice plates 21 are mutual
The one side of contact is equipped with a groove 211, and the groove 211 can be machined directly using CNC milling machine, ensure that groove
211 shape and precision, two grooves 211 surround to form the die cavity that a cross-sectional area gradually increases from the bottom to top, and when recessed
When the bottom surface and two sides of groove 211 are arc-shaped curved surface, former mould is inconvenient to process by wire cutting, and the present embodiment
The die cavity of rebound 2 surrounded and formed by the groove 211 on two pieces of splice plates 21, the groove 211 can pass through CNC milling machine
It is processed as arbitrary smooth curve so that flowing of the hot melting plastic in die cavity is more unobstructed；The lower surface of the rebound 2 and mould
The upper surface of body 1 is fixedly connected, and the upper surface of rebound 2 is fixedly connected with the lower surface of supporting plate 3, along type on the splice plate 21
The left and right sides of chamber are respectively arranged two and ranked first lock-screw 5, and first lock-screw 5 is threadedly coupled two pieces closely successively
The splice plate 21 of contact, the mode of screw-threaded coupling make it that the contact of two pieces of splice plates 21 is more close；The splice plate is about 21
End is respectively equipped with a lug boss so that the upper and lower end after the mutually splicing of two pieces of splice plates 21 formed respectively second boss 212,
First boss 213, the first clamping groove 12 are used for clamping first boss 213, so as to limit the rebound 2 of working condition
The deformation occurred by the extruding of internal hot melting plastic；The lower end of die body 1 is equipped with upwardly multiple second lock-screws 6,
Second lock-screw 6 is threadedly coupled die body 1, rebound 2 successively so that it is close overall that die body 1, rebound 2 form one
Structure.
Supporting plate 3, the upper and lower end face of the supporting plate 3 are respectively fixedly connected with the lower surface of mouth mold 4, the upper end of rebound 2
Face, the lower surface of supporting plate 3 set one second clamping groove 31, and the second clamping groove 31 is used for clamping second convex 212
Platform, so as to limit the deformation that the rebound 2 of working condition is occurred by the extruding of internal hot melting plastic.
Mouth mold 4, the upper end of the mouth mold 4 are equipped with multiple 3rd lock-screws 7, the 3rd lock-screw 7 downwards
Mouth mold 4, supporting plate 3, rebound 2 are threadedly coupled successively, mouth mold 4, supporting plate 3, rebound 2 is formed a close overall knot
Structure.
Operation principle:Die body 1, transition are squeezed into successively from the charging aperture 11 of the lower end of die body 1 by the plastics for heating treated
The inside die cavity of plate 2, supporting plate 3, finally by mouth mold 4, complete extrusion molding, the upper and lower end of rebound 2 of the present utility model
Second boss 212, first boss 213 are respectively arranged with, second boss 212, first boss 213 are respectively cooperating with being built in the second card
Tight groove 31, the first clamping groove 12, when rebound 2 is expanded deformation by the extruding of plastic cement in cavity, the first clamping is recessed
Groove 12, the second clamping groove 31 can play effect of contraction to the both ends of rebound 2, limit the dilatancy of rebound 2.
Specific embodiment of the present utility model described above, the restriction to scope of protection of the utility model is not formed.
Any various other corresponding changes and deformation made according to technical concept of the present utility model, should be included in this practicality
In new scope of the claims.
