Description
Technical field
The utility model relates to a kind of plastics batten that can be molded band simultaneously and close weld mark and docking weld mark and is molded into
Pattern has.
Background technology
During almost all of plastics processing, all there may be weld mark.Weld mark not only influences injection-molded item
Presentation quality, and weaken the mechanical property of injection-molded item, the research to weld mark is always plastics processing research
In a quite active field.
Weld mark is formed including being formed when being poured into a mould by two or more cast gates to lapping defect due to the presence of inserts
And isotopism, and wall unevenness and melt jet and the type of weld mark four that is formed.It is weld mark to lapping defect and simultaneously isotopism
The basis of research, and the emphasis of weld mark research.
For the research of weld mark, mainly around in the influence of research different materials, different technology conditions to weld mark, one
As realized by stretching of the injection molding with weld mark or impact batten.Design of the forefathers for weld mark mould mainly collects
In docking weld mark research, and the research for closing weld mark is few, and studies docking weld mark simultaneously and and close weld mark
The research of intensity, and under identical conditions, the research for comparing the intensity of two kinds of weld marks is less.
The content of the invention
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of plastic band and closed with docking weld mark
Plastics batten injection forming mold.
The purpose of this utility model is realized by following technical scheme：
A kind of plastic band simultaneously closes the plastics batten injection forming mold with docking weld mark, including：Cavity plate, top plate,
Liftout attachment, moving platen, solid plate and sprue bush；
The cavity plate is set with moving platen and is integrated, and runner and two die cavities are provided with cavity plate, its
In a die cavity be provided with inserts single cast gate cast die cavity；Another die cavity is that double cast gate pours into a mould die cavity；Described two types
Cast gate on chamber is connected with the runner respectively；
The liftout attachment includes the push rod being engaged with the die cavity, and the push rod is arranged on the top plate；
Be provided with main cast gate and the sprue being connected with the main cast gate on the sprue bush, the sprue with cavity plate
Runner be connected.
Compared with prior art, one or more embodiments of the present utility model can have the following advantages that：
The design of this plastics batten injection forming mold is unique, and structure is novel, can consider material, process conditions and system
Product structure etc. to band and close weld mark batten and dock weld mark batten influence.Using mould molding band and close weld mark and right
Weld mark plastics batten is connect, tensile bars or impact batten can be used as by interception, so as to use data characterization material, work
Skill condition and article construction etc. are to band and close the influence degree of weld mark and docking weld mark performance, suitable for various different thermoplastics
Property plastics test bars, to improve Interpretation of The Weld Mark In The Injection Molded Part intensity, weaken influence of the weld mark to injection-molded item and experiment be provided
Foundation.

Embodiment
To make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with embodiment and accompanying drawing pair
The utility model embodiment is described in further detail.
As depicted in figs. 1 and 2, it is that can be molded band simultaneously and close weld mark and dock the cavity plate of weld mark plastics batten
Structure and mould overall structure, including cavity plate 1, top plate 4, liftout attachment, moving platen, solid plate 7 and sprue bush 10；
The cavity plate is set with moving platen and is integrated, and runner 11 and two die cavities are provided with cavity plate
12, one of die cavity is the single cast gate cast die cavity for being provided with inserts；Another die cavity is that double cast gate 13 pours into a mould die cavity, described
Cast gate on two die cavities is connected (as shown in Fig. 3) with the runner respectively；
The liftout attachment includes the push rod being engaged with the die cavity, and the push rod is arranged on the top plate；
Main cast gate and the sprue 15 being connected with the main cast gate, the sprue and cavity plate are provided with the sprue bush
On runner 11 be connected.
Above-mentioned push rod 6 is distributed in the both ends of batten, does not influence the property at weld mark position through cavity plate ejection batten, push rod
Energy.
The above-mentioned die cavity for being provided with a cast gate cast, there is inserts, plastic band and the plastics batten for closing weld mark.
The above-mentioned die cavity for being provided with two cast gate cast, without inserts, the plastics batten of plastic band docking weld mark.
The inside of above-mentioned cavity plate 1 and solid plate 7 offers cooling duct 14, by cooling medium batten can be controlled to be molded
Chilling temperature after weld mark.
The appearance and size part of above-mentioned two die cavity is consistent, and one of die cavity appearance and size is standard tensile batten, separately
