Abstract
A device for the production of molded parts which includes a core carrier frame 11, and a core assembly which includes a core part 31 having a die surface 33, and an ejector plate 41 associated with the core part to form a structural unit which can be easily assembled onto and removed from the carrier frame 11. The structural unit which includes the core part 31 and the ejector plate 41 can thus be assembled to and removed from the frame 11 as an integral unit, which enables a simple and rapid equipping of the molded device for the production of a variety of products. A jacket die 51 overlies the die surface 33 of the core part 31 to form a die cavity therebetween.
Claims22
A device for the production of molded parts, comprising a core part, an ejection device operatively associated with the core part, a core carrier frame supporting the core part and the ejection device and a jacket die, wherein the core part and the jacket die are braced against each other such that they define a cavity corresponding to the molded part, wherein the core carrier is embodied as a core carrier frame which includes a passage, wherein the core part and the ejection device form a structural unit which can be inserted in the core carrier frame from one side thereof so that the ejection device extends through the passage when in an assembled state, and wherein the core carrier frame includes at least two opposing frame legs which serve to directly support the exterior of the core part and with the core part including lateral support members which rest against the core carrier frame when the device is in an assembled state.
A device for the production of molded parts, comprising
- a core carrier frame including laterally spaced apart frame legs which define a central passage therebetween,
- a core assembly which includes a core part having an upwardly facing die surface, an ejector plate which is upwardly moveable with respect to the core part and the die surface, and lateral support members connected to the core part, the core assembly forming a structural unit which can be assembled onto the core carrier frame with the lateral support members supported upon the frame legs of the core carrier frame and with the ejector plate extending through the central passage of the core carrier frame, and
- a jacket die configured to be assembled onto the core assembly so as to define a mold cavity corresponding to a molded or cast part between the upwardly facing die surface of the core assembly and the jacket die, and wherein upward movement of the ejector plate serves to eject a molded or cast part from the mold cavity.
A structural unit for a device for the production of molded parts, comprising
- a core part and an ejection device assembled to the core part,
- wherein the core part and the ejection device are carried by a core carrier and
- wherein the core part and a jacket die are braced against one another, thus embodying a cavity corresponding to the molded part, wherein the core carrier is in the form of a core carrier frame with a passage and that the structural unit can be inserted from the one side into the core carrier frame and that the ejection device extends through the passage wherein in an assembled state.
