Detailed Description
The inclined ejecting and stripping structure for injection mold of the present invention is further described with reference to fig. 1 to 2.
The utility model provides a material structure is taken off to top to one side for injection mold, characterized by: the mold comprises a front mold 1 and a rear mold 2, wherein the front mold is provided with a front mold frame 11, and the rear mold is provided with a rear mold frame 21, a supporting plate 22, a rear bottom plate 23, a top plate 24, an inclined ejector rod 41 and a mold core 3.
The support plate 22 has two pieces and is disposed between the rear mold frame 21 and the rear base plate 23, and forms a moving cavity 25 with the rear mold frame 21 and the rear base plate 23.
The top plate 24 is arranged in the moving cavity through a guide post, and the top plate 24 can move towards or back to the front mold frame 11 under the guide action of the guide post. Namely, the front and rear ends of the guide posts are respectively fixed on the rear mold frame 21 and the rear bottom plate 23, and the top plate 24 is provided with guide holes matched with the guide posts.
The front mold frame 11 and the rear mold frame 21 are respectively provided with a front mold core 111 and a rear mold core 211, the front mold core 111 and the rear mold core 211 are respectively provided with a front mold cavity and a rear mold cavity, the front mold cavity corresponds to the rear mold cavity in the front-back direction, and the rear mold frame 21 is provided with an oblique guide hole 8.
The front end 411 of the inclined ejector rod 41 and the front end of the mold core 3 penetrate through the rear mold cavity to be matched with the front mold cavity to form the mold cavity 6, the inclined ejector rod 41 is provided with two inclined ejector rods and is positioned at two sides of the mold core 3, the middle rod body part of the inclined ejector rod 41 is matched in the inclined guide hole, the rear end of the inclined ejector rod is supported on the top plate 24, and the rear end of the mold core 3 is fixed on the rear mold frame 21 through bolts.
When demoulding, the injection molding machine drives the back mould to move for a section back to the front mould, so that the front mould groove and the back mould groove are separated; after one section moves to a certain distance, the injection molding machine limits the movement of the top plate 24, and continuously drives the rear mold frame 21, the supporting plate 22 and the rear bottom plate 23 to move towards the front mold for a second section, in the process of the second section movement, the rear mold frame 21 drives the rear mold core 211 and the mold core 3 to be drawn away from the injection molding part 7, and simultaneously, the oblique guide hole performs oblique guide effect on the oblique ejector rod 41 to enable the oblique ejector rod 41 to horizontally move, so that the front end 411 of the oblique ejector rod 41 moves towards the center of the injection molding part 7, the front end of the oblique ejector rod 41 is separated from the inner wall side of the injection molding part 7 or the barb 71 on the inner top wall, and the injection molding part 7 can be separated from. The operation is simple, and the demoulding is rapid.
The embodiment is further configured as follows: the top plate 24 is detachably provided with a top block 51 for supporting the rear end of the oblique mandril 41. I.e., the top plate 24 has a mounting slot therein, and the top block 51 is detachably fixed in the mounting slot by bolts. Because kicking block 51 supports oblique ejector pin 41 to and with oblique ejector pin 41 horizontal slip friction, wearing and tearing are comparatively serious, therefore kicking block 51's detachable construction can be convenient for kicking block 51's change, reduce the utility model discloses a use cost.
The embodiment is further configured as follows: the rear end of one of the oblique ejector rods 41 is in inclined guide fit with the front end of the ejector block 51.
