Abstract
The utility model provides a PP fuse -element runner, includes sprue, runner and side gate, its characterized in that: the runner is a runner, point runner and side gate are connected, crest line and vertical direction that the sprue erected the cross -section have certain contained angle. The utility model provides a pair of PP fuse -element runner, the sprue adopts the convergent structure to increase the speed and the velocity of flow that PP moulded plastics, be equipped with the side gate, the runner tapering is also distinguished with monochromatic moulding plastics to some extent to further increase the PP injection dynamics of moulding plastics. Simple structure can effectively satisfy the requirement of PP double -shot moulding.
Description
Technical field
The present invention relates to a kind of PP melt cast gate, belong to injection molding technology field.
Background technology
In double-shot moulding, PP is common used material, owing to adopting the injection moulding respectively of two kinds of injected plastics materials, compared with homogenous material injection moulding, has certain special requirement to the version of cast gate and sprue.
Summary of the invention
For above-mentioned, the object of this invention is to provide a kind of PP melt cast gate, sprue adopts tapered configuration, to increase speed and the flow velocity of PP injection moulding; Be provided with side gate, cast gate tapering is also distinguished to some extent with monochromatic injection moulding, sprays dynamics to increase PP injection moulding further.
For achieving the above object, the present invention is realized by following technological means:
A kind of PP melt cast gate, comprise sprue, cast gate and side gate, it is characterized in that: described cast gate is spot pouring mouth, and described spot pouring mouth is connected with side gate, crest line and the vertical direction of described sprue vertical section have certain angle.
Further:
Described a kind of PP melt cast gate, is characterized in that: the crest line of described sprue vertical section and the angle of vertical direction are 2 °.
Described a kind of PP melt cast gate, is characterized in that: the crest line of described spot pouring mouth vertical section and the angle of vertical direction are 25 °.
Described a kind of PP melt cast gate, is characterized in that: the diameter of described sprue and spot pouring mouth connecting portion is 2mm.
Described a kind of PP melt cast gate, is characterized in that: described pin-point gate nozzle diameter is 0.5mm.
Described a kind of PP melt cast gate, is characterized in that: described spot pouring mouth length is 2.5mm.
Described a kind of PP melt cast gate, is characterized in that: the diameter of described side gate is 1mm.
The invention has the beneficial effects as follows: a kind of PP melt cast gate provided by the invention, sprue adopts tapered configuration, to increase speed and the flow velocity of PP injection moulding; Be provided with side gate, cast gate tapering is also distinguished to some extent with monochromatic injection moulding, sprays dynamics to increase PP injection moulding further.Structure is simple, effectively can meet the requirement of PP double-shot moulding.
