Furthermore, an ejection oil cylinder is arranged at the upper end of the mold core guide rod and is connected with the mold core guide rod and drives the mold core guide rod to move up and down.
Furthermore, the first mold core guide rod is a single-section stroke guide rod, and the second mold core guide rod is a two-section stroke guide rod.
The invention also provides a production method of the rubber injection sole with lumps, which comprises the steps of S1, closing the upper die and the lower die, injecting rubber into the die cavity for vulcanization molding; s2: separating the upper die and the lower die; s3: the first mold core guide rod and the second mold core guide rod simultaneously eject outwards for a first stroke; s4: the first mold core guide rod is ejected outwards for a second section of stroke; s5: taking out the sole and demoulding.
Furthermore, the first mold core guide rod is connected with the toe cap mold core, and the second mold core guide rod is connected with the heel mold core.
The invention has the advantages that:
the mold core is arranged in the mold cavity of the upper mold plate, and the ejection and the retraction of the mold core are controlled by an ejection oil cylinder arranged on a mold core guide rod, wherein a first mold core guide rod connected with the toe cap mold core is a two-section stroke guide rod, a second mold core guide rod connected with the heel mold core is a single-section stroke guide rod, the toe cap sole formed by injection and vulcanization is completed, the heel mold core and the toe cap mold core simultaneously eject a first section of stroke, the toe cap sole is ejected out of the mold cavity, then the toe cap mold core performs a second section of ejection stroke, the toe cap sole is separated from the heel mold core, and at the moment, the toe cap sole is manually taken out of the toe cap mold core, so that the processes of assembling the mold core and demolding the sole are omitted, and an operator can rapidly and laborsavingly complete the production process.

Detailed Description
The technical solutions in the embodiments of the present invention will be described below clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
The utility model provides an ejection mechanism of rubber injection baotou sole, includes the frame, goes up mould and lower mould, goes up the mould and rotates to be connected in the frame upper end, and the lower mould setting is at the frame lower extreme, goes up the mould and includes cope match-plate pattern, mold core and mold core guide arm, and the cope match-plate pattern is equipped with the injection chamber, and mold core guide arm are connected, and the mold core guide arm runs through the cope match-plate pattern, and the mold core guide arm drives the mold core and reciprocates. The mold core comprises a toe-in mold core and a heel mold core, the mold core guide rod comprises a first mold core guide rod and a second mold core guide rod, the first mold core guide rod is connected with the toe-in mold core, and the second mold core guide rod is connected with the heel mold core. The upper end of the mold core guide rod is provided with an ejection oil cylinder, and the ejection oil cylinder is connected with the mold core guide rod and drives the mold core guide rod to move up and down. The first mold core guide rod is a single-section stroke guide rod, and the second mold core guide rod is a two-section stroke guide rod.
A production method of rubber injection toe cap soles comprises S1, closing an upper die and a lower die, injecting rubber into a die cavity for vulcanization molding; s2: separating the upper die and the lower die; s3: the first mold core guide rod and the second mold core guide rod simultaneously eject outwards for a first stroke; s4: the first mold core guide rod is ejected outwards for a second section of stroke; s5: taking out the sole and demoulding. The first mold core guide rod is connected with the toe cap mold core, and the second mold core guide rod is connected with the heel mold core.
In the actual operation process, the mould cores can be single group or multiple groups, when multiple groups of mould cores are produced and processed simultaneously, the mould core guide rods are provided with the movable plates, and the movable plates can realize synchronous extension of the mould core guide rods of each group.
And after the toe cap sole is molded by the upper die and the lower die in a matched mode and injection vulcanization mode, the upper die and the lower die are separated, the toe cap sole covers the surface of the die core of the upper die during die separation, and the toe cap die core and the heel die core perform a first section of ejection action to eject the whole toe cap sole from the die cavity of the upper die. In this case, a large pulling force is required to directly remove the toe cap sole from the core due to the above toe cap structure. Therefore, the toe cap mold core performs the second-stage ejection action, so that the heel part of the toe cap sole is separated from the heel mold core, and the toe cap sole is only coated on the surface of the toe cap mold core after the heel part of the toe cap sole is separated, so that the toe cap mold core is very easy to take out.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it is therefore intended that the present embodiments be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
