Cross-sectional width is greater than the cross-sectional width of first connecting portion, and the angle of the first connecting portion and second connecting portion is 150 degree.
Further, the upper surface of the seal is formed with contact, and the contact is axially and symmetrically distributed on seal
The two sides on surface.
Further, the end face of the wedge-shaped head is covered with adhesive layer.
Further, the inside of the seal is formed with first row stomata.
Further, the section of the first row stomata is kidney-shaped, arc, sector, circle, rectangle, heart or bar shaped.
Further, the inside of the mosaics is formed with second row stomata.
Further, the section of the second row stomata is rectangle, circle or the oblong being vertically arranged.
Further, the second row stomata is arranged in wedge-shaped head.
Further, the seal and mosaics are integrally formed.
Further, the wedge-shaped head, first connecting portion and second connecting portion are integrally formed.
Compared with prior art, the beneficial effects of the utility model are：
A kind of polyvinyl chloride epidermis molding die special-shaped sealing strip provided by the utility model, 150 degree of second connecting portion
Bending can reduce the technique supplement region of epidermis, can preferably fit with the arc area of mold, adhesive layer can also be real
The compression deformation of sealing strip can be improved in the existing mosaics of sealing strip and being adhesively fixed for die gap, the design of gas vent,
It can guarantee to fit closely sealing strip in the low areas of mold after sealing strip surface applies pressure, improve leakproofness.This
Outside, a kind of polyvinyl chloride epidermis molding die special-shaped sealing strip provided by the utility model, structure is simple, is integrally formed, energy
Enough reduce cost.
Detailed description of the invention
In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, below will be to institute in embodiment
Attached drawing to be used is needed to be briefly described, it should be apparent that, the accompanying drawings in the following description is only to record in the utility model
Some embodiments be also possible to obtain other drawings based on these drawings for those of ordinary skill in the art.
Fig. 1 is that a kind of polyvinyl chloride epidermis molding die special-shaped sealing strip structure provided by the embodiment of the utility model is shown
It is intended to.
Description of symbols：
1, seal；2, mosaics；3, wedge-shaped head；4, first connecting portion；5, second connecting portion；6, adhesive layer；7, it touches
Head；8, first row stomata；9, second row stomata；10, antistick layer.
Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with attached drawing pair
The utility model is further detailed.
It is shown in Figure 1, a kind of polyvinyl chloride epidermis molding die special-shaped sealing strip provided by the utility model, including
The seal 1 and mosaics 2 being fixedly connected, for mosaics 1 in die gap, the lid of seal 2 is encapsulated in die gap surface,
The cross-sectional width of seal 1 is greater than the cross-sectional width of mosaics 2, and mosaics 2 successively includes wedge-shaped head 3,4 and of first connecting portion
Second connecting portion 5,4 cross-sectional width of wedge-shaped head are greater than the cross-sectional width of first connecting portion 5, first connecting portion 4 and the second connection
The angle in portion 5 is 150 degree.The bending angle of second connecting portion 5 is 150 degree, and effect is intermediate region of the sealing strip to mold
It is close, the technique supplement region of epidermis can be reduced.
In preferred embodiment, the upper surface of seal 1 is formed with contact 7, and contact 7 is axially and symmetrically distributed in seal 1
The two sides of upper surface.The section of contact 7 can be triangle, since the partial size of powder material of polyvinyl chloride is smaller, in the complex area of mold
If domain is poorly sealed, it may appear that the phenomenon that powder leakage, and the cutting-edge structure of triangle contact 7 is under pressure, Ke Yigeng
