To improve the efficiency and order of the injection molding process, the present inventors have provided for the plurality of handle cavities 53 to be regularly arranged in rows such that the handle cavities 53 are parallel to each other. In order to increase the number of zippers injected in each batch, in the embodiment, two rows of handle mold cavities 53 are arranged on the top surface of the lower mold 51, the two rows of handle mold cavities 53 are symmetrical to each other, and a positioning slot 54 is respectively arranged on the outer sides of the two rows of handle mold cavities 53.

As an illustration of the present embodiment, a top member 59 is further disposed below or at the bottom of the lower mold 51 of the present embodiment, and a top pillar 510 (or ejector pin) is disposed on the top surface of the top member 59. Correspondingly, a hole part 512 which penetrates through the lower die 51 up and down is arranged in the nozzle groove, so that the top column 510 in the top piece 59 penetrates through the hole part 512 from bottom to top of the die, the top column 510 can move up and down in the hole part 512, the highest position of the lifting of the top column 510 in the hole part 512 is higher than the bottom of the nozzle groove 55, after the injected material is plasticized and molded, the upper cover 52 is lifted, the top column 510 is lifted up at the moment, the plasticized and molded nozzle material in the nozzle groove 55 can be lifted up, the injection molded part is separated from the lower die 51, and automatic demolding is realized.

When the ejector pins are ejected, the ejector pins in the pit portions 511 are lifted to separate the nozzle material from the lower die 51, so that automatic demolding is realized.
As an illustration of the present embodiment, during design, the lifting stroke of the top pillar 510 is controlled, so that the highest position of the top pillar 510 is lower than or equal to the top surface of the lower mold 51, so as to avoid that the lifting amplitude of the nozzle material is too high to cause the nozzle material to be disconnected from the injection molded part during demolding.
As an illustration of the present embodiment, there are a plurality of the top pillars 510 designed on the top member 59, and accordingly, there are a plurality of the hole portions 512 designed on the nozzle trough 55 of the lower mold 51 for penetrating the top pillars 510, and the top pillars 510 extending from the hole portions 512 in the nozzle trough 55 are respectively located at different positions of the nozzle trough 55, so that the top pillars 510 respectively eject the plasticized nozzle material at different positions during demolding, thereby improving the stress balance of the nozzle material and avoiding breakage.
As an illustration of the present embodiment, it is preferable, but not limited to, to locate the top pillars 510 extending from the holes 512 of the nozzle groove 55 at both ends of the middle main groove of the nozzle groove 55, respectively, to improve the force balance of the nozzle when the top pillars 510 are lifted.
As an illustration of the embodiment, a limiting column 513 is further fixed at the bottom of the lower mold 51 of the embodiment, the limiting column 513 is locked at the bottom of the lower mold 51 through a screw, the ejecting member 59 is sleeved on the limiting column 513 in a penetrating manner, the ejecting member 59 is installed on the limiting column 513, the limiting column 513 is used as a main body for supporting the ejecting member 59, the ejecting member 59 is located between the limiting column 513 and the lower mold 51, and the ejecting member 59 can move up and down along the limiting column 513, when the ejecting member 59 moves up along the limiting column 513, the distance between the ejecting member 59 and the lower mold 51 is reduced, the position of each ejecting column 510 extending out of the nozzle trough 55 is raised to eject the plasticized nozzle material at the top of the ejecting column, so as to achieve demolding, the design of the limiting column 513 is favorable for limiting the lifting direction of the ejecting member 59, and the stability of the operation of the apparatus is improved.
As an illustration of this embodiment, the top member 59 may be provided with the stopper posts 513 at four corners or a plurality of positions of the base 23 of the top member 59, so that the top member 59 is stably fixed to each stopper post 513, thereby improving the supporting balance.
As an illustration of the present embodiment, springs (not shown) are sleeved at the positions 56 on the limiting columns 513, and the springs are spaced between the top member 59 and the lower mold 51 in a compressed state, so that the springs have downward pressure on the top member 59 located thereon in a normal state. When the top member 59 is acted by upward external force, the top member 59 moves upward, compresses the spring, and stops rising when the top member 59 rises to a preset height to enable the top column 510 on the top member 59 to jack up the plasticized nozzle material. By adopting the technical scheme that the spring is sleeved between the ejector 59 and the lower die 51, the ascending stroke of the ejector 59 is limited, and the phenomenon that the material is disconnected due to the fact that the lifting height of the ejection column 510 is too high due to control error is avoided.
As an illustration of the present embodiment, the lift stroke of the ejector pin is defined such that when the ejector 59 is in a state of no external force, each of the pillars 510 is located in the hole portion 512 of the nozzle groove 55 but does not protrude out of the hole portion 512 or just protrudes out of the hole portion 512 and is level with the bottom of the nozzle groove 55 outside the hole portion 512, such that the highest height of the lift thereof exceeds the nozzle groove 55, and the protruding end is lower than or level with the top surface of the lower mold 51.
The present embodiment may be, but is not limited to, a pneumatic rod or other stroke-controllable lifting member connected to the bottom of the top member 59 to drive the top member 59 to lift.
As an illustration of the present embodiment, a slot 514 may be further disposed on the lower mold 51, and the slot 514 is located between the handle cavity 53 and the positioning slot 57. Accordingly, a plurality of projections 515 are provided on the top member 59 at positions opposite to the slots 514, and the number of projections 515 is the same as the number of handle cavities 53, corresponding to each handle cavity 53. When the top piece 59 is installed at the bottom of the lower die 51, the lugs 515 extend into the slots 514, and the lugs 515 are respectively positioned at the front ends of the handle die cavities 53, when the gap of the zipper head 6 of the processed zipper is clamped into the positioning rib 58, the lugs 515 are respectively positioned in the hollow parts of the handles 8 of the zippers, and the lugs 515 are adopted for setting, so that the displacement of the handles 8 can be further avoided, and the positioning accuracy of the handles 8 is improved.
