Claims
- 1. 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.
- 2. The system as claimed in claim 1 wherein the frame opening cover plate is magnetically secured to the frame.
- 3. The system as claimed in claim 1 wherein the frame opening cover plate has selectively positioned magnetic tape to hold the cover plate over the frame opening.
- 4. 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.
- 5. The system as claimed in claim 4 wherein the frame opening cover plate is magnetically secured.
- 6. The system as claimed in claim 4 wherein the frame opening cover plate has selectively positioned magnetic tape to hold the cover plate over the frame opening.
- 7. The system as claimed in claim 4 wherein the frame opening cover plate is mechanically secured to the frame.
- 8. The system as claimed in claim 7 wherein the frame opening cover plate is secured to the frame by at least one clip having a first end and a second end.
- 9. The system as claimed in claim 8 wherein the at least one clip first end is fixedly secured to the frame opening cover plate and the at least one clip second end is releasably secured to the frame.
- 10. The system as claimed in claim 9 wherein at least one frame side wall has a clip second end receiving means, an inclined ramp extending from a frame opening to the clip second end receiving means and a recess communicating with the clip second end receiving means and extending through the side wall formed to operable receive a tool for releasing the clip second end from the clip second end receiving means.
- 11. The system as claimed in claim 10 wherein the frame opening cover plate is secured over the frame opening by urging the at least one clip second end along the inclined ramp until it is secured by the clip second end receiving means and is released from the frame opening when the operable tool is extended through the recess to disengage the clip second end from the clip second end receiving means.
- 12. The system as claimed in claim 4 wherein the frame opening housing cover plate is used to display an owner logo or name.
- 13. 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.
- 14. The system as claimed in claim 13 wherein the frame opening cover plate is magnetically secured to the frame.
- 15. The system as claimed in claim 13 wherein the frame opening cover plate has selectively positioned magnetic tape to hold the frame opening cover plate over the frame opening.
- 16. The system as claimed 13 wherein the frame opening cover plate is secured to the frame by at least one clip.
- 17. The improvement as claimed in claim 13 wherein the at least one clip is flexible and has a first end and a second end.
- 18. The improvement as claimed in claim 17 wherein the clip first end is secured to the frame opening cover plate and the second end is secured to the frame.
- 19. The improvement as claimed in claim 13 wherein the frame opening cover plate is secured to the frame by at least one clip, the clip having a first end fixedly secured to the frame opening cover plate and a second end releasably secured to the frame.
- 20. The improvement as claimed in claim 19 wherein at least one frame side wall has a clip second end receiving means, an inclined ramp extending from the frame opening to the clip second end receiving means, and a recess within the clip end receiving means extending through the frame side wall formed to operably receive a tool for releasing the clip second end from the clip second end receiving means.
- 21. The improvement as claimed in claim 13 wherein the frame opening cover plate is used to display a logo or identifying name.
