The anti-drop strip 240 is used for limiting the sliding block 310, preventing the sliding block 310 from falling out of the sliding groove 211, and facilitating the subsequent maintenance to take out the sliding block 310.

Further, in order to make the slider 310 move more stably, a limiting column 221a is arranged on the bottom surface of the sliding groove 221, and the limiting column 221a is used for being abutted against the outer wall of the slider 310, so that the slider 310 is limited. The outer wall of the upper mold core 230 is provided with a guide pin 231, the guide pin 231 is located in the sliding slot 221, the slider 310 is provided with a positioning hole, and the guide pin 231 penetrates through the positioning hole.

The working principle of the above described charger baby housing injection mold 10 is described as follows:

before injection molding, the upper mold 200 and the lower mold 100 are arranged on an injection molding machine, the mold is in a mold opening state at the moment, namely the upper mold 200 is far away from the lower mold 100, the sliding plate 220 is far away from the base frame 210 under the action of gravity and is suspended between the base frame 210 and the lower mold 100 under the combined action of the inclined guide post 320 and the slider 310, and the slider 310 is positioned at one side far away from the position of the upper mold core 230 under the action of the inclined guide post 320;

when the mold closing operation is performed, the injection molding machine drives the upper mold 200 to descend to approach the lower mold 100, the slide plate 220 contacts the lower mold 100 first, the lower mold 100 provides a supporting force for the slide plate 220, and the upper molding groove 231 and the lower molding surface together enclose the cavity 400.

Then, the upper die 200 continues to descend, the base frame 210 is close to the sliding plate 220, the distance between the sliding plate 220 and the base frame 210 is continuously reduced, the inclined guide post 320 moves along with the machine frame 210 towards the direction close to the sliding plate 220, the inclined guide post 320 pushes the slider 310 to slide towards the position close to the cavity 400 until the base frame 210 and the sliding plate 220 are attached to each other, and at the moment, the insert 330 extends into the cavity to complete the die assembly.

Then, injecting molten plastic into the cavity by the injection molding machine, after the charger housing 20 is cooled and molded, starting the injection molding machine again to drive the charger housing injection mold 10 to open the mold, lifting the base frame 210 away from the sliding plate 220, in the process, pushing the sliding block 310 to slide towards the position away from the cavity 400 by the inclined guide post 320 until the sliding block 310 slides, and when the sliding block 310 moves to the limit position, the insert 330 leaves the cavity 400, namely, at the moment, the insert 330 leaves the mounting groove 23 of the charger housing 20; at this time, the slide block 310 no longer moves relative to the position of the cavity 400, and at this time, the inclined guide post 320 and the slide block 310 cooperate to apply a vertical upward pulling force to the sliding plate 220 together, so that the sliding plate 220 rises, and the thimble in the lower die 100 lifts the charger case 20 to expose the charger case outside the injection mold 10, so as to be taken out conveniently and prepare for the next injection molding action.

Above-mentioned precious shell injection mold that charges 10 is through setting up lower mould 100, going up mould 200 and capable position subassembly 300, goes up mould 200 and adopts the sectional type design, will be used for the fashioned capable position subassembly 300 of lamp shade mounting groove to shift to last mould 200 department, makes the stroke of mould die unrestricted, when guaranteeing the precious shell that charges from this and moulding plastics the quality, realizes the quick drawing of patterns, and then improves the efficiency of moulding plastics of product.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
