A mold clamping device and a mold provided by the invention relate to the field of casting technology, including: a guide sleeve, an unlocking groove is provided at the bottom of the inner cavity of the guide sleeve; a locking seat with an axial through hole, which is elastically installed in the axial through hole There is a guide rod; the top of the locking seat has a first plug-in end that fits into the inner cavity, and the top of the guide rod has a second plug-in end that fits into the unlocking groove; the side wall of the first plug-in end is provided with The limit hole connected to the axial through hole, the limit bead is movably assembled between the side wall of the guide rod and the limit hole; the second plug-in end is wedge-shaped, and the side cavity wall of the inner cavity is provided with a limit corresponding to the limit hole groove. In the above technical solution, when the upper template and the lower template adopt any number of the clamping devices for relative clamping and locking, since the locked state length of each clamping device is the same, the positions of the upper template and the lower template can be guaranteed. Evenly clamped mold, there will be no problem that the upper template is offset relative to the lower template, thus ensuring the quality of mold clamping.
Description
technical field [0001] The invention relates to the technical field of casting, in particular to a clamping device and a mold. Background technique [0002] In the field of investment casting, a mold is a tool used to form a shape. Investment casting molds have high requirements on their own precision, and the assembly and disassembly also require professionals to operate, especially for large and complex molds, the number of live blocks can reach four to five hundred. Therefore, the positioning between the movable blocks and the mode of clamping and locking are particularly important. [0003] At present, most of the clamping and pressure maintaining of the mold during the wax filling process is realized by the clamping force of the upper and lower templates of the wax pressing equipment. For the mold whose volume exceeds the limit of the wax pressing equipment and cannot be locked by the wax pressing equipment, the mold locking method is mostly a guide post plus a screw ...
