Embodiment

[0015] The casting method of a spring seat in this embodiment includes mold making, sand mold making, casting operation, cooling treatment and casting cleaning. The mold making and sand mold making: first make a mold according to the shape of the spring seat, and then place the mold on Fill the sand mold box with resin sand, set air blow holes at the same time, harden the sand mold by blowing air, dry the mold, and then cast;

[0016] The casting operation: inject the casting solution into the mold cavity along the pouring port of the mold, the pouring temperature is 1400-1450°C, the pouring time is 15-20 seconds, and then keep warm for 20-30 minutes, the process yield 60%-70%;

[0017] The cooling treatment and cleaning of castings: cooling the obtained castings with water cooling, after cooling and forming, first open the mold to take out the castings, then clean the outer surface of the castings, and then polish them to obtain the spring seat castings after grinding.

Abstract

The invention discloses a spring seat casting method. The spring seat casting method comprises mold manufacturing, sand mold manufacturing, casting operation, cooling treatment and casting cleaning. The mold manufacturing and the sand mold manufacturing comprise manufacturing a mold according to the shape of a spring seat, placing the mold in a sand mold box, filling resin sand, arranging blow holes simultaneously, hardening the sand mold through air blow, and casting the cast mold after drying; the casting operation comprises pouring a casting solution into a cavity along a pouring opening of the cast mold, wherein the pouring temperature is in a range of 1400 DEG C to 1450 DEG C, and the pouring time is between 15 seconds and 20 seconds, and performing heat preservation for 20 minutes to 30 minutes, wherein the process yield is in a range of 60% to 70%; and cleaning and grinding the outer surface of the casting after cooling molding to obtain the spring seat cast. According to the spring seat casting method, the processing mode is simple and easy, the waste is small, and the processing efficiency is high, and the casting quality is good.

Description

[0001] technical field [0002] The invention belongs to the technical field of casting, and in particular relates to a casting process of a spring seat. [0003] Background technique [0004] The leaf spring seat plays the role of transmitting and buffering all forces and moments between the frame and the wheels, and is an important part supporting the car body and is also a vulnerable part. At present, the production process usually adopted by the leaf spring seat is three processes of pressing the left corner, pressing the right corner and punching to complete the processing. There are many molds and large investment in the above method; many processes, low processing efficiency, high cost and difficult control of processing accuracy, which cannot meet the needs of mass production. With the development of the transportation industry, the demand for spring steel plates continues to increase, and the requirements for their performance and quality are also getting higher a...
