Embodiment Construction
[0009] The two-way sequence push-out mechanism mold includes two parts, a movable mold and a fixed mold. The fixed mold is composed of a fixed mold seat plate 2, a sprue sleeve 1, a guide post 3, a limit screw 4, a fixed template 5, a pusher plate 6, a rubber 18, Core 15, screw constitute, movable mold is made of movable template 7, spacer block 8, pull rod 14, movable mold seat plate 9, push tube 13, push rod fixed plate 12, push plate 11, reset rod 19, screw.
[0010] In the fixed mold part of the mold, the sprue sleeve 1 is interference fit with the fixed mold base plate 2 and the fixed template 5, and is clearance fit with the pusher plate 6, the core 15 is interference fit with the fixed template 5, and the rubber 18 is placed in the fixed mold. The hole in the template 5 can move freely, the guide post 3 is interference fit with the fixed mold base plate 2 and the fixed template 5 and runs through the pusher plate 6, the limit screw 4 penetrates through the fixed template...

The invention relates to a two-way sequence push mechanism mold and belongs to the field of plastic molds. The mold comprises a movable mold part and a fixed mold part. In the fixed mold part, a pouring gate sleeve is in interference fit with a fixed mold seat plate and a fixed mold plate and in clearance fit with a piece push plate, cores are in interference fit with the fixed mold plate, rubber is arranged in a fixed mold plate hole and can be moved freely, a guide column is in interference fit with the fixed mold seat plate and the fixed mold plate and penetrates the piece push plate, a limiting screw penetrates the fixed mold plate to be connected with the piece push plate, and the fixed mold seat plate and the fixed mold plate are connected through a fastening screw. In the movable mold part, push pipes, a pull rod and a reset rod are arranged in a push rod fixing plate and penetrate a movable mold plate, the push rod fixing plate and a push plate are connected through a fastening screw and located on a movable mold seat plate, and the movable mold seat plate, a cushion block and the movable mold plate are sequentially connected through screws. By the adoption of the technical scheme, the two-way sequence push mechanism mold is simple in structure, easy to design and manufacture and capable of well achieving the two-way sequence push of the plastic piece.
Description
technical field [0001] The invention relates to a two-way sequential push-out mechanism mold, which belongs to the field of plastic molds and is mainly used for the ejection of plastic parts. Background technique [0002] Injection molding is a production method with a high degree of automation and high production efficiency. A reasonable mold design should be that the plastic part breaks away from the fixed mold when the mold is opened, wraps it tightly on the moving mold, and returns together with the moving mold. The ejector rod on the side ejection mechanism ejects the plastic part from the movable mold. Therefore, when designing the mold, it is necessary to fully consider the position of the parting surface, or deliberately design different draft angles of the movable mold and the fixed mold cavity, or change the position of the core, or use comprehensive measures such as the auxiliary function of pulling first and then pushing with the help of the ejector pin. To real...
