Detailed Description
For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
As shown in figures 1, 2 and 3, the utility model discloses an injection structure in cell-phone face-piece mould, including lower mould and last mould, the lower mould includes module and first ejecting structure down, the die cavity has been seted up in the module down, first liftout groove has been seted up on the die cavity bottom surface of module down, first ejecting structure is installed in first liftout groove, go up the mould and include the module, filling pipe and the ejecting structure of second, go up the bottom surface of module and seted up the die cavity complex terrace die with module down, the second liftout groove has been seted up on the bottom surface of going up the module, upward be equipped with the vertical filling pipe who link up the bottom surface on the top surface of module, upward install the ejecting structure of second in the second liftout groove of module. Through setting up first ejecting structure and the ejecting structure of second, carry out ejecting operation from last mould and lower mould respectively, realize more even ejecting. After the upper die and the lower die are pressed together, the male die of the upper die block is clamped into the die cavity of the lower die block, and materials are added through the filling pipe.
The first ejection structure comprises an ejection frame and a guide rod, the ejection frame is horizontally arranged in the first ejection groove, the upper end of the guide rod is vertically welded on the bottom surface of the ejection frame, and the lower end of the guide rod vertically penetrates through the bottom surface of the lower module. The guide rods are arranged in four corner areas of the top frame respectively, so that the uniformity of stress is guaranteed, the lower ends of the guide rods penetrate out from the bottom surface of the lower module, the lower module is convenient to move up and down to pour a demolding, and the top frame is driven to move towards the upper die when the top frame is pushed upwards.
The guide rod is sleeved with a first return spring, the first return spring is located between the bottom surface of the lower module and the lower end of the guide rod, and the upper end of the first return spring is connected with the bottom surface of the lower module. Through set up first answer spring on the guide bar, when upwards promoting the guide bar, first answer spring receives the compression, can produce upwards and decurrent elasticity simultaneously, has to be convenient for when the drawing of patterns upwards remove jack-up model and last mould drawing of patterns under the effect through first answer spring.
The second ejection structure comprises a pressing frame and an ejection column, the upper end of the ejection column vertically penetrates through the top surface of the upper module from the second ejection groove to be connected with the pressing frame, and the pressing frame is horizontally arranged on the top surface of the upper module. The pressing frame is pressed downwards from the upper direction of the upper module, so that the top column is pressed inwards, and the upper module can move up and down to pour and demould conveniently. The bottom surface of the top column is in a disc shape, so that the contact area is increased.
The top post is sleeved with a second return spring, one end of the second return spring is connected with the top surface of the upper module, and the other end of the second return spring is connected with the bottom surface of the pressing frame. When the pressing frame is extruded, the second return spring is compressed and generates elastic force at the same time, and the ejection column is pushed to move downwards under the action of the second return spring to demold the model and the upper die. The whole pressing frame can be designed into an approximate U shape, and the operation is convenient.
The side surface of the lower module is provided with a connecting support lug, so that the lower module can be supported conveniently, and the first ejection structure is guaranteed to move up and down in the lower module to pour and demould.
The utility model discloses when moulding plastics, through lower mould and last mould cooperation installation, through the terrace die on the bottom surface of last module and the die cavity grafting cooperation of module down, the terrace die extrusion of going up the module goes into the die cavity of module down in, first ejecting structure moves the shrink downwards in first ejecting groove, when the ejecting structure of second moves in the die cavity of module down, presses the extrusion of frame bottom to go up the mould, makes and presses the frame to drive fixed vertical fore-set on the bottom surface, and the die cavity of module down moves. And then injecting an injection molding solution into a mold between the lower mold and the upper mold through a filling pipe, opening the lower mold and the upper mold after injection molding and cooling are completed, installing a second ejection structure in a second ejection groove on the upper mold, pushing the ejection column to move downwards under the action of a second return spring to demold the mold and the upper mold, installing a first ejection structure in a first ejection groove in the lower mold, and moving upwards under the action of a first return spring to eject the mold and the upper mold for demolding, so that the demolding uniformity is ensured.
Although the present invention has been described in detail with reference to the embodiments, it will be apparent to those skilled in the art that modifications, equivalents, improvements, and the like can be made in the technical solutions of the foregoing embodiments or in some of the technical features of the foregoing embodiments, but those modifications, equivalents, improvements, and the like are all within the spirit and principle of the present invention.
