VI. Description of the invention: [Technology of the invention] [0001] The present invention relates to an ejection mechanism for a plastic injection mold. [Prior Art] [0002] In general, a single-cylinder injection plastic injection mold has a plastic part that is ejected by a pedestal having a long length and a relatively small diameter, and each plastic injection mold has a plurality of ejector pins. The first figure is a cross-sectional view of a plastic injection mold in a mold opening state. The plastic injection mold (not labeled) includes a female mold 50, a male mold 51 and an ejection mechanism 52. The female mold 50 is fixed to the upper support. The plate 53 is connected to the lower support plate 55 via a connecting body 54, and a cavity receiving and ejecting mechanism 52 is formed therebetween. The ejecting mechanism 52 includes a first push plate 530', a second push plate 531, a ejector pin 532, and a return position. The guide post 533, the spring 534 and the ejector rod 535, the ejector pin 532 is fixed to the second push plate 531 and can pass through the first push plate 530 and the punch 51, and the return guide post 533 is fixed to the first push plate 530, and the spring 534 sleeve On the return post 533, one end abuts the top punch 51, the other end abuts the first push plate 530, and the top rod 535 slidably passes through the lower support plate 55 against the second push plate 531. When the jack 535 is driven forward by the top ejector mechanism 52, the thimble 523 further pushes the plastic member away from the die face of the punch 51 to be taken out, and the spring 534 is in a contracted state. When the 535 is retracted, the spring force of the spring 534 drives the first push plate 530 to retreat and the ejector pin 532 to retreat until the entire ejecting mechanism 52 returns to the original position to enter the next cycle. [0003] The ejection mechanism of the plastic injection mold has a simple structure, and all of the ejector pins are used, and the ejection force is too large, which tends to cause stress concentration and whitening of the product (plastic parts), and is difficult to be ejected when the shape of the product is complicated. . Form No. 1010101 Page 5 of 17 0993277024-0 1337931 [0004] [0005] [0007] [0008] [0009] 094Π2986 August 2, 2008, according to the replacement page [invention content] In view of the above It is necessary to provide an ejection mechanism for a plastic injection mold that reduces whitening of the product and is easy to eject a complex shape product. The ejection mechanism of the plastic injection mold, the ejection mechanism comprises: a first ejection device, a second ejection device, a skew pin, a thimble, a shutter and a jack ejection device, and the first ejection device are stacked one after another , the oblique pin-end end is fixed at the other end of the first ejector device and extends axially through the first __ ejector device. The ejector pin is fixed to the second ejector and the other end is axially traversed. The ejector device extends out, the shutter is movably mounted in the first ejector device and the second ejector device, and the ejector pin end can pass through the second ejector device to abut the first ejector device. Compared with the prior art, the ejector mechanism of the plastic injection mold is used to eject the product by two-stage ejection by the slanting pin of the first component and the ejector pin of the second component. The shape of the contact surface of the top end and the product are reduced by the whitening phenomenon of the product, and the product with complicated shape can be easily ejected. The ejecting mechanism has a simple structure and convenient operation. [Embodiment] The preferred embodiment of the present invention discloses an ejection mechanism, which is particularly adapted to an ejection mechanism of a plastic injection mold. Referring to the second and third figures, the ejector mechanism of the preferred embodiment of the present invention is used for a plastic injection mold, which comprises a first body 1 'two body 2 and an ejector mechanism 3 'the first body 1 is coaxial with the second body 2 and the 'ejection mechanism 3 is movably assembled in the second body 2. The first body 1 includes a die 10 and an upper support plate 12

One end of the return guide post 392 is mounted on the first push plate 30, and the other end is extended in the accommodating space 26, the spring 394 The first push plate 30 of the top ejecting mechanism 3 is fastened to one end of the return post 3 7 , and one end abuts the punch 20 . The ejector mechanism 3 further includes a plurality of tie rods 4, one end of which is fixed to the lower support plate 24 of the second body 2, the end of which extends axially to a main rod 41, and the other end of the main rod 41 is provided Flange 40. The two ends of the second push plate 33 and the second plate 34 are provided with through holes 306 for allowing the rod 4 to pass through. The diameter of the through holes 306 is slightly larger than the diameter of the main rod 41 of the tie rod 4, and the first push plate 30 and the first The two ends of the panel 31 are also provided with through holes 308 for allowing the flange 40 to pass through. The through holes 308 have a diameter slightly larger than the diameter of the flange 40 of the tie rod 4, and the through holes 306 and the through holes 308 communicate with each other to allow the main rod 41 of the tie rod 4 to pass. Relatively moving therein, the flange 40 is received in the through hole 308 and can be pressed against the second push plate 33, and the other end is fixed to the lower support plate 24 of the second body 2, when the ejection mechanism 3 faces the top of the plastic part After the position is moved by the same distance as the main rod 41 of the tie rod 4, the flange 40 of the tie rod 4 abuts against the second push plate 33 to pull the second push plate 33 to block the advancement mechanism 3. Before the plastic part is formed, the second panel 34 of the ejector mechanism 3 is adjacent to the lower support plate 24 of the second body 2, and the flange 40 of the tie rod 4 is received in the through hole, and the plastic needs to be taken out after the mold is opened. When the ejector lever 38 is pressed against the first panel 31 and pushes it forward, the first panel 31 and the second pedal 33 are integrally connected by the shutter 37, so that the first panel 31 is driven forward. A push plate 30, the first panel 31, the second push plate 33 and the second panel 34 are synchronously advanced, and the oblique pin 35 and the thimble 36 are also advanced to advance through the oblique pin holes and the top of the punch 20, respectively. The pinhole contacts and fits the plastic part, and starts the first paragraph of the ejector form number Λ0101. Page 9/17 pages 0993277024-0 1337931 The correction page is corrected on August 02, 099, at which time the spring 394 of the return device 39 is at In the compressed state, the ram 38 continues to move until the pull rod 4 pulls the second push plate 33, so that the second push plate 33 stops, and under the continuation of the ejector lever 38, the first panel 31 continues to move forward and will open and close. The ejector pin 36 is fixed away from the second push plate 33, and the thimble 36 fixed thereon is stopped before the plastic member is no longer ejected. The first panel 31 and the first pusher 30 move in a forward movement and enter the second section to eject until the plastic member is ejected from the cavity, during which the spring 394 is further compressed. Thereafter, the jack 38 is withdrawn by the driving mechanism, and the spring force of the spring 394 pushes the first pedal 30 to return movement, and the first pedal 30 pushes the first panel 31 to perform a synchronous return motion, and presses the tail of the shutter 37 into the rear. The second push plate 33 is received in the hole 332, so that the second push plate 33 and the second plate 34 are also urged to move to the original position until resetting, ready to start the next cycle.
