Detailed Description

As shown in fig. 1-3, an injection mold ejector pin delay ejection mechanism comprises a product (1), a fixed mold plate (2), a movable mold plate (3), an ejector pin panel (4), an ejector pin bottom plate (5), a movable mold bottom plate (6), a button machine pull rod (7), a button machine stop block (8), a button machine swing block (9), a square connecting block (10), an inclined guide post (11), a slide seat (12), a slide seat (13), a slide seat cushion block (14), a product ejector pin (15), a nozzle ejector pin (16), an ejector pin fixing plate (17), an ejector pin fixing plate (18), a bolt (19), a reset spring (20), a guide post (21) and an ejector pin (22).

As shown in attached figures 1-7, when the mold is opened, the fixed mold plate (2) moves upwards relative to the movable mold plate (3), the fixed mold plate (2) drives the inclined guide post (10) and the button machine pull rod (7) to move upwards, the slide seat (12) moves horizontally rightwards along the slide seat cushion block (14) under the action of the inclined guide post (10), and the slide (13) fixedly connected with the slide seat (12) moves rightwards relative to the product (1) so that the slide (13) is separated from the product (1). When the lower end of the button machine pull rod (7) moves to the horizontal position of the upper end of the square connecting block (10), the button machine swinging block (9) is separated from the limitation of the button machine pull rod (7), and the limitation of the upward movement of the square connecting block (10) is removed. The ejector rod (22) moves upwards to drive the ejector pin fixing plate (17), the ejector pin panel (4) and the ejector pin bottom plate (5) to move upwards together, and the ejector pin plate (17) drives the product ejector pins (15) to eject the product (1) upwards, so that the water gap is separated from the product (1). When the upper end of the ejector rod (22) contacts the lower surface of the ejector rod fixing plate (18), the ejector rod fixing plate (18) moves upwards to drive the water gap ejector rod (16) to move upwards, the water gap ejector rod (16) ejects the water gap upwards, the ejector rod (22) continues to move upwards to drive the product ejector pin (15) and the water gap ejector rod (16) to move upwards together, and finally the water gap and the product (1) are ejected simultaneously, so that the process and the cost for manually cutting off the water gap are reduced, and the production efficiency of the mold is improved.

As shown in the attached drawings 1-7, when the die is closed, the button machine pull rod (7) moves downwards, and when the lower end of the button machine pull rod (7) is contacted with the left side of the button machine swinging block (9), the pressing button machine swinging block (9) swings towards the lower right. When the left end of the button machine swinging block (9) is in surface contact with the upper surface of the square connecting block (10), the button machine swinging block (9) downwards compresses the square connecting block (10), the square connecting block (10) downwards moves under the combined action of the button machine swinging block (9) and the reset spring (20), the ejector pin panel (4) and the ejector pin bottom plate (5) downwards move, the ejector pin fixing plate (17) and the ejector pin fixing plate (18) downwards move, and the product ejector pin (15) and the water gap ejector pin (16) reset. The button machine pull rod (7) and the fixed die plate (2) continue to move downwards, the inclined guide post (11) moves downwards, the slide (13) moves leftwards along the slide seat cushion block (14), and the slide (13) resets. The mold closing sequence avoids the interference between the slide (13) and the product thimble (15).

The above description is of the preferred embodiment of the present invention, and is intended to illustrate the content and the idea of the present invention, and the content of the present invention should not be construed as limiting the present invention.
