Detailed Description
The following description of the present invention will be made with reference to the accompanying drawings 1-3.
The first core-pulling device for the injection plastic mold comprises an ejector pin bottom plate 9 and an ejector pin panel 8 which are fixedly connected in sequence from bottom to top, wherein a bearing plate 7 is arranged above the ejector pin panel 8, a movable mold core fixing plate 6 is fixedly arranged on the bearing plate 7, a movable mold fixing plate 14 and a fixed mold fixing plate 13 are sequentially arranged above the movable mold core fixing plate 6, a movable mold 3 is fixedly arranged in the movable mold fixing plate 14, a fixed mold 2 is fixedly arranged in the fixed mold fixing plate 13, a product molding area 12 is formed among the movable mold 3, the fixed mold 2 and the movable mold core 4, the movable mold core 4 is positioned in the fixed mold 2, and the movable mold 3 and the movable mold core fixing plate; the bottom end of the thimble 5 is fixed between a thimble bottom plate 9 and a thimble panel 8, and the top end of the thimble 5 sequentially passes through the thimble panel 8, the bearing plate 7 and the movable mould core 4 to be contacted with a product molding area 12; the bottom end of the nylon expansion sleeve 1 is fixed in the movable module fixing plate 14, and a nylon expansion sleeve hole is correspondingly formed in the fixed module fixing plate 13; the top of the limit screw 10 is fixed in the movable mould fixing plate 14, the bottom is positioned in the thimble base plate 9 and the thimble panel 8, the limit screw 10 is sleeved with a spring 11, and the spring 11 is positioned in the movable mould core fixing plate 6.
The thimble bottom plate 9 is arranged on the moving die base plate.
The top of thimble panel 8 is provided with carrier plate 7 through the cushion that is located movable mould bedplate both sides, and movable mould bedplate, cushion, carrier plate 7 are by supreme fixed connection in proper order down.
The fixed die block fixing plate 13 is fixed below the fixed die base plate.
In the first stage, a mold closing product is molded, then the mold opening process is carried out, because the nylon expansion sleeve 1 has a locking force between the fixed mold block fixing plate 13 and the movable mold block fixing plate 14, the fixed mold block fixing plate 13, the movable mold block fixing plate 14, the fixed mold block 2 and the movable mold block 3 cannot be opened, immediately under the assistance of the spring 11, the movable mold core fixing plate 6, the movable mold core 4 and other movable mold sides (a bearing plate 7, an ejector pin panel 8, an ejector pin bottom plate 9 and an ejector pin 5) can move towards the movable mold together, the moving distance is controlled by a distance L from the limiting screw 10 to the movable mold core fixing plate 6, and the movable mold core 4 must be completely separated from a molding area on the inner side of the.
And then the movable mould side continues to move towards the movable mould, at the moment, because the movable mould core fixing plate 6 applies force to the limiting screw 10, when the force is greater than the locking force of the nylon expansion sleeve 1 between the fixed mould fixing plate 13 and the movable mould fixing plate 14, the fixed mould fixing plate 13 and the movable mould fixing plate 14 are opened.
And finally, in the product ejection stage, because the movable mold core 4 with the largest wrapping force on the product is drawn out of the product molding area 12, the force of the ejector pin panel 8 and the ejector pin bottom plate 9 for driving the ejector pin 5 to eject the product is much smaller, and the product is ejected perfectly.
Above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the design of the present invention, equivalent replacement or change should be covered within the protection scope of the present invention.
