Precoated sand casting equipment

Abstract

The scheme discloses precoated sand casting equipment which comprises a concave frame, the back face of the concave frame is fixedly connected with a back plate, the front face of the back plate is fixedly connected with a top plate, the upper surface of the top plate is fixedly connected with a first electric push rod, and the telescopic end of the first electric push rod penetrates through the inner wall of the back plate and is fixedly connected with a connecting plate; and the two ends of the upper surface of the connecting plate fixedly communicate with pouring pipes, the center of the bottom face of the connecting plate is fixedly connected with a mold core, and a first mold and a second mold are arranged below the connecting plate. The precoated sand casting equipment is reasonable in design structure, through cooperation of a second electric push rod, a linkage block, hinge rods, linkage rods, push plates, push blocks, the first electric push rod and the connecting plate, the effects of automatic mold opening and closing are achieved, bucket teeth can be conveniently taken out from the interior of a mold cavity, and the production efficiency of the bucket teeth can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of metal coated sand casting, in particular to a coated sand casting equipment suitable for excavator bucket teeth. Background technique [0002] Excavator bucket teeth are important consumable parts on excavators. Similar to human teeth, they are combined bucket teeth composed of tooth seats and tooth tips, and the two are connected by pins. Since the worn out part of the bucket tooth is the tooth tip, it is only necessary to replace the tip, which is classified according to the environment in which the bucket teeth of the excavator are used. Excavator bucket teeth can be divided into rock teeth (for iron ore, quarry, etc.), earth square teeth (for digging soil, sand, etc.), conical teeth (for coal mines), according to the tooth seat: Excavator bucket teeth can be divided into vertical pin bucket teeth (mainly Hitachi excavators), horizontal pin bucket teeth (Komatsu excavators, Carter excavators, Daewoo e...

AI Technical Summary

Problems solved by technology

Due to the ingredients of some precision coated sand casting bucket teeth, their wear resistance and quality even exceed that of forging coated sand casting bucket teeth. Therefore, precision coated sand casting bucket teeth are the mainstream manufacturing process of bucket teeth in the market, but bucket teeth After the tooth is cooled and formed in the mold, it is not easy to demould, which seriously affects the production efficiency of the bucket tooth; therefore, we provide a coated sand casting equipment to solve the above problems
