Description
Technical field
Injection mold field is the utility model is related to, more particularly relates to a kind of two impression injection molding mould.
Background technology
The runner design of existing injection mold is often designed using single channel, and this design is different in the thickness of injecting products
When, for material when by relatively thin position, its speed can be than comparatively fast causing the thickness at this to be unable to reach the thickness of design, simultaneously
Outer surface cooling velocity in thicker position expands outwardly than the material at very fast center, makes the lack of fill at center, forms vacuum
Bubble, the poor fluidity of material also result in form bubble, cause injecting products unqualified.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of by thing in runner and temperature control pipeline guarantee die cavity
The motion homogeneous of material reduces product bubble, reduces the inferior rate of product, two impression injection molding mould.
In order to solve the above technical problems, the technical solution of the utility model is：
A kind of two impression injection molding mould, including two dynamic models and a cover half, two dynamic model is located at left and right sides of cover half, described
Two dynamic models are located at left and right sides of cover half, and the cover half and two dynamic models cooperatively form two types cavity, and the cover half center is provided with vertical current
Road, the vertical run bottom are connected with longitudinal runner, and longitudinal runner both ends pass through transverse flow channels and two types cavity respectively
It is connected, the transverse flow channels are respectively communicated with the both ends of die cavity side, and the dynamic model is equipped with temperature control pipeline, institute with cover half
State temperature control pipeline to be respectively uniformly distributed around two types cavity so that it is uniform that material enters flow velocity of the rear material in die cavity.
Preferably, the cover half is provided with locating rod, and the locating rod is extended vertically through in dynamic model and cover half.Locating rod can make
The position for obtaining dynamic model and cover half is relatively fixed, and the size of die cavity is relatively stable.
Preferably, the cover half is equipped with air discharge duct in dynamic model both sides.Air in die cavity is discharged, it is effectively anti-
Only there is bubble.
Preferably, the temperature control pipeline is cylinder.It is easy to the flowing and heating of coolant.
Compared with prior art, the utility model advantageous effects are mainly reflected in：The utility model is set by dual channel
Meter ensures that material after vertical run entrance, is shunted by longitudinal runner, then the mistake of corresponding die cavity is transported to by four transverse flow channels
Cheng Zhong, and the Flow of Goods and Materials speed inside die cavity are uniform and stable, by the design of locating rod, by between dynamic model and cover half
Position relationship mutually determines, ensures that the shape of die cavity is basically unchanged, and is worked as by the design to air discharge duct in die cavity and enters material, air
Outwards overflow therewith, air is discharged by air discharge duct, when mould can be preheated and cooled down by using temperature control pipeline
Temperature be controlled, preheating ensures that flow velocity of the material in injection moulding process is uniform, and temperature in use control pipeline during cooling makes
Product cooling is uniform, the utility model is simple in construction, novel in design, accords with the demands of the market, and is adapted to large-scale promotion.

Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the present utility model is described in further detail, so that the utility model skill
Art scheme is more readily understood and grasped.
As shown in figure 1, a kind of two impression injection molding mould, including two dynamic models 1 and a cover half 3, two dynamic model 1 are located at cover half
3 left and right sides, the dynamic model 1 of cover half 3 and two cooperatively form two types cavity 7, and the center of cover half 3 is provided with vertical run 5, described to hang down
The bottom of straight channel 5 is connected with longitudinal runner 9, and longitudinal both ends of runner 9 are connected by transverse flow channels 6 with two types cavity 7 respectively
Logical, the transverse flow channels 6 are respectively communicated with the both ends of the side of die cavity 7, and the dynamic model 1 is equipped with temperature control pipeline 8 with cover half 3,
The temperature control pipeline 8 is respectively uniformly distributed around two types cavity 7, and the cover half 3 is provided with locating rod 2, and the locating rod 2 is hung down
Directly through dynamic model 1 and cover half 3, the cover half 3 is equipped with air discharge duct 4 in the both sides of dynamic model 1, and the temperature control pipeline 8 is circle
Cylinder.
A kind of above-mentioned middle operation principle of two impression injection molding mould is as follows：Dynamic model 1 is put into from the both sides of cover half 3, then will
Locating rod 2 is through to rear side from the front side of cover half 3 so that the inner thickness of die cavity 7 and shape invariance, material is from vertical run 5 with molten
Melt state inflow to shunt in longitudinal runner 9, the end that longitudinal runner 9 is reached after material diversion is further separated into transverse flow channels 6, leads to
Cross that the material of transverse flow channels 6 is uniform, at the uniform velocity enter die cavity 7, temperature in use control pipeline 8 is entered to mould before injecting material
Row preheating, ensure that material flow of the material in die cavity 7 is uniform and stable, product will not be because of the not smooth caused bubble of Flow of Goods and Materials
And product defect, in injection moulding process, prevent occurring bubble in the product as the injection air of material overflows from air discharge duct 4,
Treat that material fills die cavity 7, product cooled down by temperature control pipeline 8, be evenly distributed on die cavity 7 design cause no matter
It is that preheating or cooling can be carried out rapidly and uniformly.
Certainly, it the above is only concrete application example of the present utility model, the scope of protection of the utility model do not formed and appointed
What is limited.All technical schemes formed using equivalent transformation or equivalent replacement, all fall within the utility model rights protection model
Within enclosing.
