Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment provides a mold bidirectional side core pulling mechanism as shown in fig. 2-4.

The inclined guide post 1 is fixed on the fixed die side of the die.

The movable template part comprises a side-pulling slide block component 2, a mold core 4, a movable template 5, a pressure plate 7 and a guide limit plate 8. The core 4 is fixed to the moving platen 5. The two pressing plates 7 are fixed on the movable template 5 through bolts 6 to form a T-shaped groove matched with the T-shaped structure at the bottom of the sliding block 2-1. And a guide limit plate 8 (shown in figures 8-9) is also fixed at the corresponding position of the movable template 5 through bolts.

The side draw slide assembly 2 comprises a slide 2-1 (shown in figure 5), a fixed side core 2-2 (shown in figure 6), a movable side core 2-3 (shown in figure 7), a limiting pin 2-4 and the like. The slide block 2-1 can slide in a T-shaped groove formed by the press plates 7 on the two sides, the fixed side core 2-2 is fixed on the slide block 2-1 through a bolt, and the movable side core 2-3 is in sliding fit with the fixed side core 2-2 through a dovetail groove. The limiting pin 2-4 is fixed on the fixed side core 2-2 and is matched with the long groove 2-3-2 on the movable side core 2-3 for limiting, and the lug boss 2-3-3 at the forming end is a lateral forming structure at the position of the plastic part B. The guide limiting plate 8 is fixed at the corresponding position of the movable template through a bolt, a limiting groove 8-1 of the guide limiting plate is in sliding fit with a boss 2-3-1 at the non-forming end of the movable side core 2-3 (the sliding length of the boss 2-3-1 at the non-forming end in the limiting groove 8-1 is the side pulling length of the movable side core 2-3), and when the movable side core 2-3 is reset, the C surface of the guide limiting plate 8 is just attached to the E surface of the guide limiting plate 8.

When the mold works, as shown in fig. 10-11, a moving mold and a fixed mold are separated, the inclined guide post 1 drives the sliding block 2-1 to move towards the outer side, the movable side core 2-3 can only laterally move along the direction of the limiting groove 8-1 due to the guiding action between the boss 2-3-1 at the non-forming end and the limiting groove 8-1 of the guiding limiting plate 8, as shown in fig. 10, when the boss 2-3-1 at the non-forming end of the movable side core 2-3 is separated from the D surface of the guiding limiting plate 8, the side core pulling at the position of a plastic part B is finished, and simultaneously, due to the action of the limiting pin 2-4, the movable side core 2-3 moves towards the outer side along with the sliding block 2-1 and the fixed side core 2-2, and the side core pulling at the position. When the die is closed, the inclined guide post 1 drives the slide block 2-1 to move towards the inner side, when the C surface of the movable side core 2-3 touches the E surface of the guide limiting plate 8, the slide block 2-1 drives the fixed side core 2-2 to continue moving towards the inner side, the movable side core 2-3 can only move along the direction of the guide limiting plate limiting groove 8-1 due to the dovetail groove between the movable side core 2-3 and the fixed side core 2-2, and finally, the reset is completed to prepare for the next forming.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
