Abstract
An frame opening cover plate for an injection mold system having an upper stationary portion and a lower movable portion. The upper portion has a support member and a cavity core, while the lower portion has a frame having side walls, a bottom and a support member defining an interior housing with openings on each end. An ejector assembly is positioned within the housing and is movable to eject newly molded products when a molded product has been formed. The openings in the frame can result in the collection of dust, moisture and other foreign materials inside the housing and the possible damage to the mold or ejector assembly, so a frame cover plate is provided. A cover plate covers each opening during operation of the system and when the system is inactive or stored.
Claims21
An injection mold system comprising:
- an upper stationary portion including a support member and an upper cavity core secured to the support member;
- a lower movable portion including a frame with an opening, a lower support member forming a top for the frame and opening, and a lower cavity core carried by the lower support member, the lower movable portion movable toward the upper stationary portion until the lower cavity core engages the upper cavity core to form a full cavity shaped to make a desired product;
- an ejector assembly operable to eject molded products from the mold system when the upper cavity and lower cavity cores are separated after molding;
- and a frame opening cover plate secured at least to the frame to close the frame opening and thereby prevent the entry of dust, moisture and other foreign materials into the frame opening.
An injection mold system comprising:
- an upper support and cavity core portion and a lower portion including a frame having side walls, at least one end opening, a lower support member forming a top for the frame and the at least one end opening, and a lower cavity core carried by the lower support member, the lower portion movable toward the upper portion until the upper and lower portions join to form a full cavity shaped to make a defined product;
- an ejector assembly operable to eject molded defined products from the mold system when the upper and lower portions are separated;
- and a frame opening cover plate secured at least to the frame to close the frame opening and thereby prevent the entry of dust, moisture and other foreign materials.
An improved injection mold system of the type having an upper stationary portion including an upper support member and upper cavity core, a lower movable portion having a frame with side walls. an opening forming an ejector housing, a lower support member forming a top for the frame and opening, a lower cavity core carried by the lower support member, the lower support portion movable toward the upper stationary portion until the lower cavity core engages the upper cavity core to form a full cavity shaped to make a designed product, an ejector assembly having an interior platen and ejector rods positioned within the opening operable to eject molded products from the mold system when the upper and lower cavity cores are separated after molding, wherein the improvement comprises:
- a frame opening cover plate secured at least to the frame to close the frame opening and prevent the entry of dust, moisture and other foreign materials into the frame opening.
The system as claimed 13 wherein the frame opening cover plate is secured to the frame by at least one clip.
