Embodiment 1

[0031] see Figure 1-3 As shown, the present invention is an injection mold, including a movable mold assembly and a fixed mold assembly; the movable mold assembly includes a movable mold 1 and a hot runner plate 2 , and the fixed mold assembly includes a fixed mold 5 and a push plate 501 . The movable mold 1 is provided with two mold cavities 101; the hot runner plate 2 is connected with two hot nozzles 201 and two telescopic devices 202, which correspond to the positions of the mold cavities 101.

[0032] Such as Figure 4 As mentioned above, the telescopic device 202 is a double-headed cylinder; one end of the telescopic rod of the telescopic device 202 is connected with a thimble 203 extending into the hot nozzle 201, and the other end runs through the fixed plate of the movable mold assembly. The telescopic rod of the telescopic device 202 and the thimble 203 are both hollow tubular structures, and one end of the telescopic rod of the telescopic device 202 is connected w...

Embodiment 2

[0038] Such as Figure 1-6 As shown, a mold demoulding mechanism adopting the injection mold in Embodiment 1, the push plate 501 is screwed with the draft rod 6 . The upper surface of the draft rod 6 is welded with a fixed plate 601; the upper surface of the fixed plate 601 is slidably connected with a transmission rack 602 through a slide rail slider; The rotation of transmission wheel 402.

[0039] The end of the fixing plate 601 away from the push plate 501 is welded with a first side plate 603 ; the side of the transmission rack 602 is welded with a second side plate 604 . A spring 605 is fixedly connected between the first side plate 603 and the second side plate 604 . The end of the draft rod 6 away from the push plate 501 is fixedly connected with a stopper 606; the side of the movable mold 1 is fixedly connected with a stopper 607 corresponding to the position of the stopper 606, which is used to move through the movable mold 1, and the stopper 607 and the stopper are ...

Abstract

The invention discloses a mold demolding mechanism, an injection mold and a system, and relates to the technical field of injection molds. A telescopic rod of a hollow tubular structure and an ejector pin of a hollow tubular structure are included, and one end of the telescopic rod of a telescopic device is connected with an air source; a cavity plate is movably connected in a cavity; a rack is connected to the side face of the cavity plate. a movable mold is rotatably connected with a rotating shaft, and one end of the rotating shaft is connected with a gear meshing with the rack, and the other end of the rotating shaft is connected with a transmission wheel. The mold demolding mechanism of the injection mold comprises a mold pulling rod, and the mold pulling rod is in sliding connection with a transmission rack; and the transmission rack is used for meshing with the transmission wheel, and rotation of the transmission wheel is achieved through movement of the movable mold. The ejector pin of the hollow structure is connected with the air source, and the problem that an existing storage battery shell and a cavity are not separated in time is solved. The cavity plate is driven to move by the mold pulling rod and the rotating shaft of the demolding mechanism, so that demolding of the storage battery shell is realized, the demolding reliability is improved, and the problem of low production efficiency in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of injection molds, in particular to a mold demoulding mechanism, an injection mold and a system. Background technique [0002] At present, when the 20F hot runner bottom shell is opened, the product is easy to suck into the cavity: since the cavity is in a state of natural suction when the mold is opened, when the suction volume is insufficient, the injection molded battery case will be adsorbed on the cavity, making the battery case The demoulding speed is slow, and the average production cycle of one mold is 48 seconds to 50 seconds. The production cycle is longer, which affects the overall production efficiency. Simultaneously, the case that the battery case is adsorbed on the cavity and cannot be separated will also occur. If the battery case that has not been separated from the mold is not cleaned in time, the injection molding machine will not be able to produce normally, seriously affecting the overa...
