Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment:
Please see Fig. 2 to Fig. 4, the utility model provides a kind of automatic ejection degumming mechanism, including rear cavity 1, rear mould bases
2, support block 3, bottom plate 4, lower ejector retainner plate 5, upper ejector retainner plate 6, thimble 7 and draw material pin 8, it is described after mould bases 2, support block 3 and
Bottom plate 4 is fixedly connected sequentially, and the upper ejector retainner plate 6 is located at the rear mould bases 2 and the bottom plate 4 with lower ejector retainner plate 5
Between, the thimble 7 is fixedly connected with the upper ejector retainner plate 6, the drawing material pin 8 sequentially pass through the upper ejector retainner plate 6 with it is described
Lower ejector retainner plate 5, and the tail end of the drawing material pin 8 is extended downward into and is contacted with the bottom plate 4, the flow path groove 9 of the rear cavity 1
It is inside provided with the back-off structure 10 of the runner for being formed after fixed injection molding, is offered on the lower ejector retainner plate 5 for described
Material pin 8 is drawn to postpone the emptiness avoiding hole 11 of backform.
The working principle of the utility model are as follows: be provided in the flow path groove 9 of rear cavity 1 after fixing injection molding and form runner
Back-off structure 10, which can use conical socket structure, and the bottom of the conical socket and drawing 8 top of material pin are neat
Flat, when being molded, the gelatinous injection molding glue of fluid can be entered in back taper groove, the injection molding in conical socket after cooling
Glue, which is formed, draws material block, then carries out backform operation with lower ejector retainner plate 5 by moving up upper ejector retainner plate 6, is fixed on thimble
The thimble 7 of plate 6 can follow hard on ejector retainner plate 6 and move up together, and draw material pin 8 due to be across upper ejector retainner plate 6 and lower ejector retainner plate 5,
It is not to be fixedly connected between upper ejector retainner plate 6 and lower ejector retainner plate 5, can be formed between upper ejector retainner plate 6 and lower ejector retainner plate 5 opposite
Mobile, in addition the corresponding position for drawing material pin pedestal 12 offers emptiness avoiding hole 11, the depth of the emptiness avoiding hole 11 on lower ejector retainner plate 5
Draw material pin pedestal 12 that can be introduced into emptiness avoiding hole 11, therefore draw at this time during lower ejector retainner plate 5 moves up for 5-8mm
Material pin 8 will not temporarily can be moved up with upper ejector retainner plate 6 and lower ejector retainner plate 5, product after thimble 7 starts ejection injection molding upwards,
Runner is an integral structure with the drawing material block in conical socket at this time, is that pyramidal structure cannot be out of conical socket due to drawing material block
The runner for pulling out, therefore being formed easily in flow path groove 9 can be drawn material block to pull fixation, will not be pushed up together with the product of ejection
Out, becoming between runner and product at this time will form a reversed pulling force, this reversal interlocking relay can be arranged thimble 7 continue upper top and
It is gradually increased, when reversal interlocking relay is greater than the attachment force between product and runner, runner and product can be pullled disconnection, and then
As lower ejector retainner plate 5 continues to move up, draw material pin pedestal 12 that can gradually be displaced downwardly to 11 bottom of emptiness avoiding hole, due to drawing material pin pedestal 12 straight
Diameter is greater than the diameter for drawing 8 active tunnel of material pin, when lower ejector retainner plate 5 continues to move up, draws material pin 8 also can be with lower ejector retainner plate 5
Move up together, drawing material block of the final shaping in conical socket is ejected by drawing material pin 8, during entire backform upper ejector retainner plate 6 with
Lower ejector retainner plate 5 can move up 30mm or so together, move up the depth that distance is far longer than emptiness avoiding hole 11, designed by this kind and realize production
Separation and the final operation being all ejected between product and runner.
Based on above-mentioned, the utility model has advantages in that the utility model is tied by opening up emptiness avoiding hole and back-off
Structure can finally realize the separation ejection between product and runner, reduce the process that subsequent artefacts trim runner, improve life
Produce efficiency, whole design is simple for structure practical, it is easy to operate and convenient for promote.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
