Said core locating slot center of loosing core has the exhaust consent of loosing core; Loose core and be provided with venting plug in exhaust consent and the exhaust consent;
The said locating piece of loosing core is designed to cone boss; The said locating slot of loosing core is designed to conical socket; Loose core in a said left side and right pattern draft of loosing core is 0 °~15 °.
The advantage and the beneficial effect of the utility model are:
1, the utility model is through being replaced with the metal type dies casting to oil-well rig clutch aluminium alloy brake shoe by traditional sand mold die casting; Through die cast; Product structure is even; Can reach designing requirement fully, solve that the aluminium alloy brake shoe structural homogeneity that traditional processing technology produces is poor, intensity and hardness low shortcoming.
2, the utility model has guaranteed the quality conformance of brake shoe production and the uniformity of product size through low pressure casting technology and technological the mutually combining of die cast, and has realized the mass production of product, has improved production capacity.
3, the utility model is through the rig clutch aluminium alloy brake shoe of controlling automatically and pressure pouring is cast; Obviously eliminated the casting flaw such as pore, pin hole, slag inclusion, crackle of aluminium alloy brake shoe; Foundry goods is organized fine and close, and mechanical property is higher by 15%~20% than sand casting.
4, the utility model is in rig clutch aluminium alloy brake shoe manufacture process, adopts metallic core and resin coating sand core to combine, and the air vent of the aluminium alloy brake shoe of casting and the square hole of working do not influence the installation and the serviceability of product.
5, the metal mold of the utility model periphery of loosing core has all designed fillet, has guaranteed the arc transition of cast member periphery junction, has both helped formed product, has strengthened casting strength again; In order to guarantee the linearity of work square hole, can assemble other auxiliary members smoothly, adopt the casting of coated sand core, characteristics such as resin peritonaeum core has the intensity height, and it is few to get angry have solved traditional handicraft and have done core with clay-bonded sand and be prone to defeated and dispersed problem.
6, the pattern draft of loosing core of the utility model is 0 °~15 °, helps extracting fast metallic core, prevents to pull foundry goods.
