Description

A kind of practicality can hide the mould structure of glue-feeder
Technical field
The utility model relates to injection mold field, particularly a kind ofly realizes the mould structure of injection-molded finished surface without glue-feeder vestige.
Background technology
By injection machine injection moulding out, such efficiency is higher for general plastic product part.And the cast gate that enters of finished parts is arranged on finished parts surface or side usually, facilitate the design of mould, but some plastic product surface and periphery require, have not allowed glue-feeder vestige high.And cutting technique good is more also difficult to ensure that the cutting of glue-feeder vestige is clean, this reality raises new difficuties with regard to the arrangement for mould.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of practicality can hide the mould structure of glue-feeder.
The utility model solves the technical scheme that its technical problem adopts:
A kind of practicality can hide the mould structure of glue-feeder, comprise the moving platen of upper end and the solid plate of lower end, telescopic flexible angle ejector rod is provided with in described solid plate, the rear side of described flexible angle ejector rod is provided with runner, described moving platen, the die cavity for injecting products is provided with between solid plate and flexible angle ejector rod, wherein said flexible angle ejector rod upper end is provided with towards product side inserts to the plate of die cavity for injection-molded finished pit bit, described plate lower surface rearward end and finished product pit bit, the junction of runner is set to into cast gate, described glue-feeder is by the second angle ejector rod, glue injection channel in moving platen is connected with the gum-injecting port of moving platen outer surface.
As a preference, described flexible angle ejector rod place oblique runner direction between die cavity and runner.
As a preference, the lower end of described plate has the L font groove around plate towards edge, product place, back edge, described L font groove with enter cast gate and be communicated with.
The beneficial effects of the utility model are: this mould structure is by reasonably improvement, particularly combined by angle ejector rod, and the design arranged in angle ejector rod into cast gate, make injection-molded finished glue-feeder vestige be hidden in injection-molded finished bending position or the inconspicuous place of pit bit, ensure outer surface smoother.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is schematic perspective view of the present utility model;
Fig. 2 is the schematic perspective view of the utility model when angle ejector rod jack-up;
Fig. 3 is the partial enlarged drawing of a-quadrant in Fig. 2;
Fig. 4 is the partial enlarged drawing at the utility model centerboard part place.
Detailed description of the invention
With reference to Fig. 1 ~ Fig. 4, a kind of practicality can hide the mould structure of glue-feeder, comprise the moving platen 1 of upper end and the solid plate 2 of lower end, telescopic flexible angle ejector rod 3 is provided with in described solid plate 2, the rear side of described flexible angle ejector rod 3 is provided with runner 4, described moving platen 1, between solid plate 2 and flexible angle ejector rod 3, be provided with die cavity 6 for injecting products 5, just become runner materials and parts 41 after the material of this outer flow passage 4 li solidifies and be processed.Wherein said flexible angle ejector rod 3 upper end is provided with towards product 5 side inserts to the plate 31 of die cavity 6 for injection-molded finished pit bit 51, the junction of described plate 31 lower surface rearward end and finished product pit bit 51, runner 4 is set to into cast gate 7, that is space can be left between plate 31 lower surface and die cavity 6, main for finished product pit bit 51, plate 31 lower surface rearward end is as the binding site between finished product pit bit 51 and runner materials and parts 41 simultaneously.Described enter cast gate 7 be connected by the gum-injecting port of the runner 4 in moving platen 1, solid plate 2 with moving platen 1 outer surface.Wherein said flexible angle ejector rod 3 place oblique runner 4 direction between die cavity 6 and runner 4, make the plate 31 of flexible angle ejector rod 3 deviate from from finished product pit bit 51 smoothly.
Should be noted that, finished product pit bit 51 can be as product 5 part, also can as the waste material that must excise, only as transition materials and parts of runner materials and parts 41 and product 5.As another embodiment, with reference to Fig. 3, Fig. 4, the lower end of described plate 31 has the L font groove 32 around plate 31 towards edge, product 5 place, back edge, described L font groove 32 with enter cast gate 7 and be communicated with, as the use of injection-molded finished pit bit 51, the groove of this shape had both facilitated the design of runner 4, also facilitated the demoulding of product 5.After the demoulding, the finished product pit bit 51 of L font groove 32 li just can have been excised.
When the actual demoulding, first moving platen 1 has risen the first demoulding, then flexible angle ejector rod 3 rises, wherein due to flexible angle ejector rod 3 oblique runner 4 direction, the plate 31 of flexible angle ejector rod 3 is thrown off from injection-molded finished pit bit 51, the plate 31 of simultaneous retractable angle ejector rod 3 also injects finished product pit bit 51, and therefore flexible angle ejector rod 3 is also responsible for whole injecting products 5 jack-up.This completes whole knockout course.
According to above-mentioned principle, the utility model can also carry out suitable change and amendment to above-mentioned embodiment, and such as, in above-mentioned moving platen 1 and solid plate 2, die cavity 6 can be symmetrically distributed in runner 4 both sides.Therefore, the utility model is not limited to detailed description of the invention disclosed and described above, also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.
