Embodiment Construction
[0011] As shown in the figure, it is an easy-to-turn lost foam casting sand box. One side wall of the sand box body 1 is a side door 5 that can be opened to take out the casting mold. A support roller 2, the position corresponding to the support roller 2 is provided with a balance roller 3, which is used to keep the sand box body 1 stable; the support roller 2 is hinged with a support frame 7, and the sand box body 1 is connected to the side door The opposite side of 5 is provided with hoisting ring 6, which is used to hoist the rear part of the sand box body 1 and make it rotate around the support frame 7 to take out the casting mold therein.
[0012] The above is the basic implementation mode of the present invention, and further improvement or optimization can be made on the basis of the above:
[0013] For example, the support roller 2 and the balance roller 3 are rotatably installed on the bottom of the flask body 1, so that the flask body 1 can move in a rolling manner. ...

The invention relates to an easily turned lost foam casting sandbox, which is characterized in that one sidewall of the sandbox is an openable side door for removing a mold, a sealing door is arranged outside the side door, a supporting roller is arranged at the bottom of the side door, a balance roller is arranged at the position corresponding to the supporting roller for keeping smooth and steady of the sandbox; a bracing frame is hinged to the supporting roller, a hoisting ring is arranged on one surface of the sandbox relative to the side door for hoisting the rear part of the sandbox and winding on the bracing frame for rotating to remove the mold. According to the invention, the side door is opened at the lateral part of the sandbox, and the supporting roller and the bracing frame are arranged at the bottom of the side door, so that little force is applied at the rear part of the sandbox for overturning the sandbox, and the modeling sand is dumped to complete the mold stripping work; simultaneously, for avoiding the dispersion of the modeling sand in the side door, the sealing door is arranged outside the side door, so that the sealing of the sandbox can be realized due to different opening mode of the side door and the sealing door.
Description
technical field [0001] The invention relates to lost foam in the field of mechanical casting, in particular to an easy-to-turn lost foam casting sand box. Background technique [0002] Lost foam casting (also known as solid casting) is made of foam plastic (EPS, STMMA or EPMMA) polymer material to form a solid mold with exactly the same structure and size as the part to be cast, after dipping refractory coating (strengthening , bright and clean, air-permeable) and dried, buried in dry quartz sand and subjected to three-dimensional vibration modeling, pouring molten metal into the casting mold sand box under negative pressure, so that the polymer material model is heated and gasified and drawn out, and then is cast Liquid metal replaces the one-time molding casting new technology formed after cooling and solidification to produce a new casting method for castings. [0003] The existing lost foam casting sand box is a simple sand box. In the process of turning over the box an...
