Изобретение относитс к литейному производству, в частности к литью под давлением роторов, имеющих скос пазов и заливаемых без вала или сменной оправки.The invention relates to foundry, in particular, to the injection molding of rotors with bevel slots and cast without a shaft or a replaceable mandrel.
Наиболее близким к изобретению по техническому решению вл етс форма дл лить под давлением ротора электродвигателей, содержаща неподвижную полуформу с матрицей и подвижную полуформу с пуансоном, выталкивател ми и контрвыталкивател ми. На одном из контрвыталкивателей установлена коса шпонка, предназначенна дл придани скоса пазам пакета ротора 1 .The closest to the invention according to the technical solution is the form for casting under the pressure of a rotor electric motors, comprising a fixed mold half with a die and a moving mold half with a punch, ejectors and counter pushers. On one of the counter-pushers, a braid key is installed, designed to give a bevel to the grooves of the rotor package 1.
Недостатком известной пресс-формы вл етс то, что она не позвол ет заливать роторы, имеющие такие конот. руктивные особенности, как: мала площадь роторного листа, ограниченна пощадь поджима пакета ротора матрицей к пуансоном. Мала .площадь роторного листа затрудн ет шихтовку пакета на скобу; ограниченна площадь поджима-влечет за собой сн тие пакета в месте поджима или его перекос , выбрызгивание металла по плоскости разъема формы и облив пакета ротора жидким металлом по наружномуA disadvantage of the known mold is that it does not allow casting of rotors having such cavities. Operational features, such as: small area of the rotor sheet, limited to the compression of the rotor package by the matrix to the punch. The small area of the rotor sheet makes it difficult to pack the package on the bracket; the limited area of the pressing-up entails the removal of the package in the place of the pressing or its tilting, spraying the metal along the plane of the mold connector and pouring the package of the rotor with liquid metal on the outside
диаметру. Кроме того, пресс-форма имеет еще и тот недостаток, что при такой ее конструкции необходимо установить на контрвыталкиватели и сориентировать по косой шпонке предварительно зашихтованный на скобу пакет в рабочей зоне пресс-форме, при этом скоба должна иметь тот же скос, что и коса шпонка. Однако примене10 ние скобы со скосом затрудн ет шихтовку пакета на нее, а пр мую скобу перед ориентацией пакета на косую шпонку необходимо извлекать из пакета, что ведет к увеличению трудоемкости, так как нужна ориентаци практически каждой пластины в отдельности .diameter. In addition, the mold also has the disadvantage that, with such a design, it is necessary to install the counter pushers and orient the oblique key previously secured to the bracket in the working area of the mold, using the slanted key, and the brace should have the same bevel key. However, the use of a bevel with a bevel makes it difficult to package the package on it, and the straight bracket must be removed from the package before orientation of the package to the oblique key, which leads to an increase in labor intensity, since it is necessary to orient virtually every plate separately.
цель изобретени - предотвращение деформации пакета ротора и упрощение The purpose of the invention is to prevent deformation of the rotor package and simplify
