Description
Technical field
The utility model relates to a kind of injection molds.
Background technique
Injection molding, also call action mould, the course of work is that the material of heated thawing is injected die cavity by high pressure, through cold
But after solidifying, formed products are obtained.In the prior art, when being molded large volume component, need to be injected into a large amount of melted material, but
Be due to injection device capacity limit, can not the complete die cavity of disposal pouring, generally require repeatedly to be poured, thus front and back two parts
For the compartment of casting there is temperature difference, temperature difference causes component inside stress to be concentrated, and thus will appear deformation, is thus molded
The component precision of generation is not up to standard.It would therefore be desirable to have a kind of devices can overcome the defect.
Utility model content
In order to solve the problems, such as background technique, the utility model proposes a kind of large capacity high pressure bitubulars continuously to infuse
Mold is penetrated, which is injected simultaneously by two runners, avoided because repeatedly pouring there are two cylinder is molded
The poor phenomenon of precision caused by note.
In order to achieve the above objectives, the utility model adopts the following technical solution：
A kind of continuous injection molding of the large capacity high pressure bitubular, including bed die, the upper surface central part of bed die are provided with down
Recessed lower former, the top of bed die are provided with upper mold, are provided with the upper former being recessed upwards on the lower surface of upper mold, more than upper former
Lower former position is opposite, and die cavity is formed between upper former and lower former, there is two injection channels, setting in injection channel in upper mold
There is pouring cylinder, guide sleeve is provided with above two pouring cylinders, horizontal runner, the both ends of runner are provided in guide sleeve
It is provided with vertical branch flow passage, branch flow passage extend into the center of pouring cylinder, and the position that branch flow passage is located at pouring cylinder bottom is set as
Cast gate, branch flow passage pass through cast gate and mould cavity.
The upper surface both ends of upper mold are provided with bracket, and mould bases is provided at the top of bracket, and the center of mould bases is provided with water conservancy diversion
The center of column, diversion column and guide sleeve is fixedly linked, and the center of diversion column is provided with sprue, and sprue upper end is injection hole,
The lower end of sprue is communicated with horizontal runner.
The lower surface of guide sleeve is provided centrally with downwardly projecting locating piece, and upper mold is arranged in by locating piece in guide sleeve
Upper face center.
The upper end opening of injection channel is arranged on the upper surface of upper mold, and the lower ending opening of injection channel is opened in former
On bottom surface.
Injection channel is divided into two parts, and the upper channel and diameter being relatively large in diameter are less than the lower channel of upper channel, pouring cylinder
Top has top cover, and top cover is covered on the upper surface of upper mold.
Pouring cylinder, which is located at outside the circumference of upper channel inner part, is provided with spring.
The utility model has the beneficial effects that：Injection device injects high pressure melted material into sprue by injection hole,
Melted material into sprue is entered in branch flow passage by runner, carries out both ends casting simultaneously by branch flow passage, can
Avoid the excessively poor phenomenon of precision caused by front and back is repeatedly poured.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawing
Fig. 1 is the schematic diagram of the section structure of injection molding described in the utility model；
Specific embodiment
Explanation and specific embodiment are further described the utility model with reference to the accompanying drawing：
Embodiment 1
A kind of continuous injection molding of the large capacity high pressure bitubular, as shown in Figure 1, including bed die 1, the upper surface center of bed die 1
Part is provided with recessed lower former, and the top of bed die 1 is provided with upper mold 2, is provided on the lower surface of upper mold 2 and is recessed upwards
Upper former 13, upper 13 remaining former position of former is opposite, forms die cavity 14 between the remaining former of upper former 13, is molded in die cavity 14
The component of needs is generated afterwards.There are two injection channels in upper mold 2, the upper surface of upper mold 2 is arranged in the upper end opening of injection channel
On, the lower ending opening of injection channel is opened on the bottom surface of former 13.Injection channel is divided into two parts, the upper channel being relatively large in diameter
It is less than the lower channel of upper channel with diameter, pouring cylinder 10 is provided in injection channel, the top of pouring cylinder 10 has top cover, top cover
It is covered on the upper surface of upper mold 2.Pouring cylinder 10, which is located at outside the circumference of upper channel inner part, is provided with spring 11.
The top of two pouring cylinders 10 is provided with guide sleeve 7, and the lower surface of guide sleeve 7, which is provided centrally with, downwardly projecting determines
Position block, the upper face center of upper mold 2 is arranged in by locating piece 7 for guide sleeve 7, and its both ends is fixed on the top of pouring cylinder 10
Portion.
Horizontal runner 8 is provided in guide sleeve 7, the both ends of runner 8 are provided with vertical branch flow passage 9, branch flow passage 9
It is extend into the center of pouring cylinder 10, the position that branch flow passage 9 is located at 10 bottom of pouring cylinder is set as cast gate 12, and branch flow passage 9 is by pouring
