Embodiment Construction

[0022] Below in conjunction with the drawings, preferred embodiments of the present invention are given and described in detail.

[0023] Herein, "up", "down", "left", and "right" are only used to indicate the direction of relative movement for convenience when describing the embodiments in conjunction with the drawings, and are not specifically limited to this direction.

[0024] Such as image 3 As shown, the mold with mechanical reverse ejection mechanism according to the present invention has locking block 11, reverse ejector block 12, slide block 21, fixed block 211 and anti ejector pin similarly to the existing mold with hydraulic type reverse ejector structure 212. Specifically, the fixed mold 1 is provided with a locking block 11 and an anti-jack block 12, the locking block 11 is fixedly connected to the fixed mold 1, and the anti-jack block 12 can move up and down relative to the fixed mold 1; The inclined guide column is provided with a slide block 21 , on which a ...

Abstract

The invention relates to a mold with a mechanical reverse ejecting mechanism. The mold comprises a fixed mold and a movable mold. A locking block is fixedly connected with the fixed mold, a reverse ejecting block capable of moving vertically is arranged on the fixed mold, a vertical spring is arranged between the top face of the reverse ejecting block and the fixed mold, a movable block is arranged on the lateral face, opposite to the locking block, of the reverse ejecting block, a horizontal spring is arranged between the movable block and the reverse ejecting block, and an ejecting block which is matched with the movable block and protrudes upwards is fixedly arranged on the movable mold. According to the mold with the mechanical reverse ejecting mechanism, oil cylinders in an existing multi-color injection mold and complex action signal control systems are omitted, and accurate ejecting of the reverse ejecting action of the sliding block can be achieved only by the arrangement of the springs and the movable block, so that the cost of the mold and the complexity of the structure are greatly reduced.

Description

technical field [0001] The invention relates to a multi-color injection mold, in particular to a mold with a mechanical reverse ejection mechanism. Background technique [0002] In the existing conventional mold structure, the anti-ejection mechanism is used to eject the product when the mold is closed and opened. Such as figure 1 As shown, the fixed mold 1a of the mold is fixedly provided with a locking block 11a, and the movable mold 2a is provided with a slider 21a through an inclined guide column (not shown), and the slider 21a is fixedly connected with a fixed block 211a, through which The fixing block 211a is provided with an anti-thimble 212a, and the end of the anti-thimble 212a away from the fixing block 211a directly abuts against the product 3a. During mold closing and mold opening, the counter ejector pin 212a is subjected to the action of the locking block 11a to eject the product 3a to the left. [0003] In the multi-color injection mold, since the slider ne...
