Problems solved by technology

[0004] 2. During the stirring process of raw materials, the mixture is easy to adhere to the stirring device due to the existence of stirring centrifugal force. When the adhesion layer reaches a certain thickness, it will affect the smooth operation of the stirring structure, and it is easy to cause waste of raw materials. At the same time In the process of mixing the raw sand with the binder without screening, it is easy to produce a large volume of mixed cohesive lumps, and the side of the mixed cohesive lumps is likely to affect the subsequent casting

Embodiment Construction

[0035] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but the present invention can be implemented in many different ways that are predetermined and covered by the claims.

[0036] Such as Figure 1 to Figure 9 As shown, a chemical hardening sand casting process uses a chemical hardening sand casting device, the chemical hardening sand casting device includes a base 1, a stirring mechanism 2 and a feeding mechanism 3, using the above chemical hardening sand casting device for chemical The specific casting process of hardened sand casting is as follows:

[0037] S1. Adding raw sand: Pour the raw sand into the inner groove of the sieve plate 34 manually, and at the same time drive the splint 33 to reciprocate backwards through the electric slider 32, and the splint 33 drives the sieve to move synchronously to the raw sand. Screening, the raw sand in the screening falls into the mixing tank 21;

Abstract

The invention relates to a chemical hardening sand mold casting process which uses a chemical hardening sand mold casting device. The chemical hardening sand mold casting device comprises a base, a stirring mechanism and a feeding mechanism, the lower end of the base is installed on the existing working ground, the stirring mechanism is installed at the upper end of the base, and the feeding mechanism is installed at the lower end of the base. According to the chemical hardening sand mold casting device, chemical hardening sand mold casting is carried out by adopting the design concept of a stirring and feeding matched structure, and the feeding mechanism can be matched with the operation of the stirring mechanism to realize intermittent feeding, so that raw material can be fully mixed andfully utilized; meanwhile, other auxiliary stirring mechanisms are additionally arranged under the condition that the basic stirring structure is arranged, so that the purpose of improving the mixingdegree between the raw material is achieved.

Description

technical field [0001] The invention relates to the technical field of sand casting, in particular to a chemical hardening sand casting process. Background technique [0002] Sand casting refers to the casting method that produces castings in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. Because the molding materials used in sand casting are cheap and easy to obtain, the casting mold is easy to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings. For a long time, it has been the basic process in casting production and the basic The raw materials are foundry sand and sand binder. The most commonly used foundry sand is siliceous sand. The molds used in sand casting are generally composed of outer sand molds and cores. The cores are also called clay cores or cores. It is used to form the internal structure of the casting. It is usually made of core sand made of raw sand a...
