Detailed Description
The present invention will be described in further detail with reference to the following examples and drawings, but the present invention is not limited thereto.
The utility model discloses a concrete implementation process as follows: as shown in fig. 4 to 10, a combined straight-top disengaging and reversing mechanism is characterized in that a straight-top base 2 is fixedly arranged on an ejector plate 1, a first sliding groove 21 is arranged on the straight-top base 2, the first sliding groove 21 is arranged along the extending direction of the diameter of a product 100, a straight top 3 slidably connected with the first sliding groove 21 is arranged on the straight-top base 2, a product following block 4 is fixedly arranged on one side of the straight top 3 close to the product 100 and is adapted to the contour of the product following block 4 on one side of the product 100, an reversing groove 41 for accommodating a product reversing 101 is arranged on the product following block 4, a second sliding groove 42 is arranged on one side of the product following block 4 away from the product 100, the second sliding groove 42 is obliquely arranged from top to bottom towards one side of the product 100, a trapezoidal insert 5 slidably connected with the second sliding groove 42 is arranged on the product following block 4, a bone position groove 51 adapted to a bone position 102 of the product 100 is arranged on the upper surface of the trapezoidal insert 5, the trapezoidal insert 5 is fixedly arranged with an external structural part. When the top surface of the trapezoidal insert 5 is flush with the top surface of the product following block 4, the trapezoidal insert 5 and the product following block 4 form part of the outer contour of the product inverted buckle 101 and the bone position 102. When the injection molding is carried out, the top surface of the trapezoidal insert 5 is flush with the top surface of the product following block 4 by moving the ejector plate 1, the injection molding of the product 100 is completed by matching with other injection molding inserts, when the injection molding of the product 100 is completed, the straight top 3 is driven to move upwards by moving the ejector plate 1 so as to drive the product following block 4 to move upwards, the product following block 4 moves upwards so as to eject the injection molded product 100, and further the bone position 102 is separated from the trapezoidal insert 5, because the product following block 4 is in sliding connection with the trapezoidal insert 5, the trapezoidal insert 5 is mutually interfered with the product following block 4 through the second chute 42 with inclination in the ascending process of the product following block 4, because the trapezoidal insert 5 is fixedly arranged with an external structural component, the product following block 4 drives the straight top 3 to slide in the chute of the straight top base 2 to the side far away from the product 100, and further the back-off button 101 is separated from the product following block 4, and the overall effect that the product following, the product following block 4 and the trapezoidal insert 5 interfere with each other in the ascending process, so that the product following block 4 and the straight top 3 move towards the direction away from the product 100 and are finally separated from the product 100, and finally the product 100 is taken out through a clamp manipulator or manually; after the injection molding mold is taken out, the ejector plate 1 moves downwards, the straight top base 2 drives the straight top 3 and the product following block 4 to move downwards, the product following block 4 and the trapezoidal insert 5 are mutually interfered, and the trapezoidal insert 5 is a fixing part, so that the product following block 4 moves downwards in the moving-down process and moves towards the direction close to the product 100, the ejector plate 1 stops moving downwards when the top surfaces of the trapezoidal insert 5 and the product following block 4 are flush, and other injection molding inserts are matched and installed to complete injection molding again.
Preferably, as shown in fig. 6 and 7, a protrusion is downwardly disposed at a connection position of the straight top 3 and the product following block 4, and the protrusion can enhance strength of the connection position of the product following block 4 and the straight top 3.
In a preferred scheme, an extension block extends from the top of the straight top 3 to the direction of the product 100, the product following block 4 is fixedly connected with the straight top 3 through the extension block, a protrusion is arranged below the extension block, and the extension block is arranged to enable the straight top 3 to avoid a thin steel area as far as possible.
Preferably, still include and directly push up guide block 6, it is vertical to be equipped with straight top 3 guiding hole on the guide block 6 to directly push up, straight top 3 passes straight top 3 guiding hole and restricts and slides in straight top 3 guiding hole, straight top guide block 6 and external structure fixed connection. Through setting up straight top guide block 6 and directly pushing up guide block 6 when thimble board 1 drives straight top 3 and moves down can prevent straight top 3 roll-off straight top base 2, straight top guide block 6 plays spacing effect. When the ejector plate 1 moves upwards, the straight top 3 moves rightwards, and the straight top 3 can be contacted with the straight top guide block 6 before contacting the trapezoidal insert 5 by setting the width and the position of the guide hole, so that the trapezoidal insert 5 is prevented from deforming due to the fact that the straight top 3 is contacted with the trapezoidal insert 5 by inertia; through the width and the position that set up the guiding hole, can also make straight top 3 drop to remove thimble board 1 with 5 top surfaces of trapezoidal mold insert and product along with the 4 top surfaces of piece at ordinary times with straight top guide block 6 contact, avoid making to remove thimble board 1 along with the 4 top surfaces of piece height irregularity with 5 top surfaces of trapezoidal mold insert and product owing to drive arrangement's inertia, set up straight top guide block 6 and can also place straight top 3 roll-off straight top base 2 when sliding on the top base.
Referring to fig. 8, preferably, a straight top groove 52 for accommodating the straight top 3 is formed in the bottom of the trapezoidal insert 5 on the side close to the straight top 3, and by providing the straight top groove 52, the straight top 3 can be inserted into the straight top groove 52, so that the combined straight top 3 can be separated from the back-off mechanism more compactly, and the occupied space is smaller.
Referring to fig. 8 again, preferably, the number of the second sliding grooves 42 is two, the second sliding grooves 42 are respectively disposed in the product following blocks 4 on both sides of the straight top 3, and the trapezoidal insert 5 is provided with a second sliding rail adapted to the second sliding grooves 42.
