Embodiment Construction
[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0027] refer to figure 1 and Figure 4 , the preferred embodiment of the present invention provides a top mold mechanism, which is used to be installed in the mold block 10, so as to abut against the molded part to be ejected under the action of external force to make the molded part and the mold block 10 conform to each other. The cavity surface 101 is separated and resets automatically after the external force is eliminated. The top mold mechanism includes: a top mold plate 20 for bearing the action force, and the top mold plate 20 is connected with a top mold rod 30 for resisting the molded part. The outer circle of the top mold rod 30 The top is equipped with an elastic member 40 that is compressed when the force is applied and automatically re...

The invention discloses a die propping mechanism and a mold with the die propping mechanism. The die propping mechanism comprises a die propping plate, wherein the die propping plate is used for bearing acting force; a die propping rod is connected to the die propping plate, and is used for bunting and propping a shaped piece; an elastic piece is mounted on an outer circle of the die propping rod, when being applied by the acting force, the elastic piece is compressed, and after the acting force is eliminated, the elastic piece is automatically recovered to an initial state; the end part of one end of the elastic piece is used for bunting and propping the die propping plate; a mounting channel allowing the die propping mechanism to be mounted is formed in a mold moving block; one end of the mounting channel communicates with a cavity surface; the die propping mechanism is mounted in the mounting channel in a sliding manner, and the end part of the other end of the elastic piece is used for bunting and propping the mounting channel; a die propping hole is formed in the mold moving block, and communicates with the mounting channel to enable an external force application mechanism to apply the acting force on the die propping plate; the force application mechanism penetrates through the die propping hole to apply the acting force on the die propping plate; and the die propping plate translates and compresses the elastic piece to enable the die propping rod to slide out of the mounting channel to bunt and prop the shaped piece; and after the force application mechanism is removed, the die propping rod and the die propping plate are automatically recovered to an initial position under the effect of the elastic piece.
Description
technical field [0001] The invention relates to the field of precision casting, in particular to a top mold mechanism. In addition, the present invention also relates to a mold comprising the above-mentioned top mold mechanism. Background technique [0002] With the development of precision casting technology, the structure of parts is becoming more and more complex, and there are more and more parts with characteristics such as distortion, narrowness, and thin wall, and the structure of the wax mold or ceramic core that shapes its structure is also becoming more and more Complicated, wax molds or ceramic cores are not smooth and easy to produce cracks, deformation, etc. How to ensure smooth wax molds or ceramic cores with twisted, narrow, thin-walled structures has become a difficult problem in the mold design and manufacturing process . [0003] At present, the top mold mechanism is generally used to release the wax mold or ceramic core with a twisted, narrow, thin-walle...
