The purpose of this utility model is achieved in that
The disposable casting mould of permanent magnet motor housing, on the slideway of mold base upper surface by mold left side dynamic model piece, mold right side dynamic model piece and mold initiatively module surround the mold shell body, the middle part of the cavity at mold shell body middle part is provided with loam core in the mold that forms cavities in motor field frame, in mold, be provided with the mold water channel loam core of the C type of the heat dissipation channel that forms motor field frame on the external cylindrical surface in loam core, the C type opening part in mold water channel loam core is provided with the mold terminal box loam core that forms the terminal box on motor field frame, the outer wall in loam core and mold left side dynamic model piece in mold, between the inwall of mold right side dynamic model piece and mold active module, be provided with the gap that forms the motor field frame inner and outer wall, both ends, mold water channel loam core radially be provided with extend out to mold initiatively the inwall of module be abutted against the inlet that forms heat dissipation channel and the extension of liquid outlet.
Above-mentioned mold active module is positioned at the front side of mold left side dynamic model piece, mold right side dynamic model piece, and the C type opening in described mold water channel loam core faces initiatively module of mold.
Above-mentioned mold left side dynamic model piece and the junction, middle part of mold right side dynamic model piece are respectively arranged with groove longitudinally, and the longitudinal fluting cooperation of mold left side dynamic model piece and mold right side dynamic model piece is fastened on the mold base on the limited block at this place.
Slideway on above-mentioned mold base upper surface has the transverse slipway of mold left side dynamic model piece and mold right side dynamic model piece downside and the end slipway of mold active module downside; mold left side dynamic model piece and mold right side dynamic model piece can laterally slide with matched moulds or die sinking on transverse slipway, mold active module can be on end slipway longitudinal sliding motion with matched moulds or die sinking.
The utility model outstanding and useful technique effect compared to existing technology is:
1, the utility model utilizes on the mold base mold left side dynamic model piece is set, mold right side dynamic model piece and mold initiatively module surround the mold shell body, loam core in the inner chamber of mold shell body, mold being set, mold water channel loam core, the mode in mold terminal box loam core, the loam core moulding such as the heat dissipation channel dexterously needs are welded to connect, making permanent magnet motor housing and heat dissipation channel is the integral structure of casting, the producers that increase because of the welding heat dissipation channel have been reduced, material, machining period, bad seepage caused of welding quality etc. and the production cost that causes is high, production efficiency is low, the problems such as the quality of production is poor,
2, with the product thickness everywhere of the utility model casting in strict conformity with designing requirement, good cooling results, heat dispersion is stable, long service life;
3, of the present utility model simple in structure, moulding is easy, and production cost is low, and production efficiency is high, and the good product quality of producing is applicable to the powerful permanent magnet motor housing of integral type casting with heat dissipation channel.
