Detailed Description
To facilitate understanding of those skilled in the art, the structure of the present invention will now be described in further detail with reference to the following examples:
example one
Referring to fig. 1-3, a rapid demoulding mold suitable for an oil cup cover comprises a front mold 1 and a rear mold 2 which are arranged in a sealing manner, wherein the front mold 1 is provided with a heat flow channel (not shown), the front mold 1 and the rear mold 2 are arranged in a vertically corresponding manner, the rear mold 2 is provided with a plurality of injection molding mechanisms 5 (for convenience of display, only one injection molding mechanism is shown in fig. 1), an injection molding cavity 6 is arranged between the front mold 1 and the injection molding mechanism 5, the heat flow channel is communicated with the injection molding cavity 6,
a push plate 3 capable of moving up and down is arranged between the front die 1 and the rear die 2;
the injection molding mechanism 5 includes:
a group of movable plates 56 which are correspondingly arranged up and down, wherein the movable plates 56 are fixedly connected to the push plate 3, and the movable plates 56 are provided with a plurality of gaps;
the core 51 is fixedly arranged on the rear die 2, the core 51 is in a circular truncated cone structure with a narrow top and a wide bottom, and the core penetrates through the movable plate 56;
the first guide rod 52 and the second guide rod 53 are arranged in an equiangular staggered manner with the core 51 as a center, the first guide rod 52 and the second guide rod 53 are arranged between the notches, the bottom ends of the first guide rod 52 and the second guide rod 53 are fixedly connected to the rear mold 2, and an inclined surface is arranged on one surface of the first guide rod 52 and the second guide rod 53 facing the core 51;
a first slider 54 and a second slider 55 respectively disposed in a gap between the first guide bar 52 and the second guide bar 53 and the core 51, the first slider 54 and the second slider 55 facing one of the cores 51
The surface of the core 51 is provided with an inclined surface which is in inclined fit with the core 51, one surface of the first sliding block 54 facing the first guide rod 52 is provided with an inclined surface which is in inclined fit with the first guide rod 53, one surface of the second sliding block 55 facing the second guide rod 53 is provided with an inclined surface which is in inclined fit with the second guide rod 53, and the upper surfaces of the first sliding block 54 and the second sliding block 55 form an outer circular ring structure of the core 51.
