Compared with the prior art, the utility model has the following beneficial effects: compared with a rotary demolding structure, the structure is simpler, more efficient, stable and reliable in action, capable of being used for a long time, saving the mold space and reducing the mold cost;

1. according to the utility model, through the arrangement of the pressing plate, the large row position, the small row position and the base, the large row position and the small row position of the equipment are limited through the pressing plate and the base, so that the large row position and the small row position can stably operate during working, the mechanism is stable and reliable in action, and can be used for a long time;

2. according to the utility model, through the arrangement of the large slide and the small slide, the equipment drives the three large slides and the three small slides to move by utilizing the action of the die sinking machinery, so that the three large slides and the three small slides can be simultaneously contracted towards the center, thus core pulling is realized, internal threads are separated, and the mechanism has simple structure and high efficiency;

3. according to the utility model, through the arrangement of the large slide, the small slide and the shoveling machine, the equipment can complete work mainly through the large slide and the small slide, and the shoveling machine is also arranged inside the large slide and the small slide, so that the space inside the large slide and the small slide can be utilized, the mechanism can save the die space, and the die cost is reduced.

Detailed Description

As shown in fig. 1 to 5, the die structure of the inner retracting row position comprises a product 1 and a shovel machine 6, wherein the product 1 is internally connected with a large row position 3, the back inclination of the large row position 3 is 4 degrees, the large row position 3 is in sliding connection with the shovel machine 6, a small row position 4 is embedded between the two large row positions 3, the back inclination of the small row position 4 is 9 degrees, the three large row positions 3 and the three small row positions 4 can form a circle around the shovel machine 6, the small row positions 4 are in sliding connection with the shovel machine 6, the lower end of the large row position 3 is connected with a pressing plate 2, the lower end of the pressing plate 2 is connected with a base 5, the shovel machine 6 is positioned inside the base 5, the central axis of the shovel machine 6 is superposed with the central axis of the base 5, the central axis of the base 5 is also superposed with the central axis of the pressing plate 2, the large row positions 3 are arranged in three around the shovel machine 6, the large row positions 3 are distributed around the shovel machine 6 at equal intervals, the small row positions 4 are distributed around the shovel machine 6 at equal intervals, and three connecting bolts 7 are equidistantly penetrated in the base 5.

Product 1 is the product that equipment final processing came out, the bottom edge does not take out tooth spline groove characteristic, connecting bolt 7 can be in the same place clamp plate 2 and base 5 erection joint, clamp plate 2 and base 5 can carry on spacingly to big capable position 3 and little capable position 4, make big capable position 3 and little capable position 4 can stable operation when carrying out the during operation, make this mechanism action reliable and stable, can use for a long time, utilize the die sinking mechanical action to make three big capable position 3 and three little capable position 4 contract to the center simultaneously, thereby realize loosing core, break away from the internal thread, make this mechanism simple structure, high efficiency, shovel machine 6 sets up in the inside of big capable position 3 and little capable position 4, can utilize the space of big capable position 3 and little capable position 4 inside, make this mechanism can save the mould space, reduce the mould cost.

The working principle is as follows: when the mold structure with the inner shrinkage line position is used, after the injection molding of a product is finished, the injection molding machine mechanism ejects a mold KO insert and an ejector plate, and simultaneously pushes a plate B to be separated from a supporting plate, the supporting plate drives a shovel machine 6 to be pulled out backwards, the shovel machine 6 drives a large line position 3 and a small line position 4 to simultaneously and synchronously contract in a phase center mode through a dovetail groove, so that the core pulling is realized, the internal thread is separated, the inclination of the back of the small line position 4 is set to be 2 times greater than that of 3 large line positions 3, therefore, the core pulling speed of the small line position 4 is always 2 times greater than that of the large line position 3, the three large line positions 3 and the three small line positions 4 are enabled to have a sequence at the beginning moment of core pulling, a certain gap is always kept in the core pulling process, so that the large line position 3 and the small line position 4 are ensured not to be interfered and blocked, a connecting bolt 7 can connect a pressing plate 2 and a base 5 together, and the joint of the pressing plate 2 and the base 5 is provided with a groove space, thereby can be convenient for big line position 3 and little line position 4 shrink and remove, clamp plate 2 and base 5 also have and carry out spacing effect to the removal of big line position 3 and little line position 4.
