Embodiment Construction

[0035] The present invention is described in detail below in conjunction with accompanying drawing:

[0036] For mold water cooling purposes, refer to Figure 8 , the water-cooled pipe pre-embedded casting technical scheme of the present invention is as follows:

[0037] The first step is to use the CNC machining center to process a set of polystyrene foam molds and bend the stainless steel tubes into water-cooled tubes according to the required water-cooling path.

[0038] refer to figure 1 , figure 1 A schematic diagram of the pre-assembly of the water cooling tube and the white mold;

[0039] The white mold refers to the polystyrene foam mold;

[0040] "White mold" is processed by CNC machining center according to the needs of polystyrene sheet.

[0041] The water-cooled pipe is based on the cooling water cooling path given in the design, using a pipe bender or pipe bending fixture to bend the stainless steel pipe into a pipe of the shape required by the design.

Abstract

The invention belongs to the technical field of casting, and relates to a casting method of a stainless steel water cooling pipe embedded mold. The method comprises the following steps that a foam pattern and a matching water cooling pipe are machined; sand burying molding is carried out on the foam pattern; after the foam pattern is removed, a complete mold cavity is reserved; the water cooling pipe is put into the mold cavity and fixed, and displacement of the water cooling pipe in a pouring process is prevented; a box is closed; and casting molding and shakeout cleaning are conducted; the water cooling pipe is put into the mold cavity to be fixed, and the displacement of the water cooling pipe is prevented in the pouring process; after the water cooling pipe is put into the mold cavity,the outer joint of the water cooling pipe is subjected to landfill treatment; the foam pattern is machined through a numerical control machining center according to needs; and the foam pattern is made of a polystyrene material. According to the casting method of the stainless steel water cooling pipe pre-embedded mold, the water-cooling layout is flexible and can be carried out along with the shape of the mold, stainless steel pipe fittings are equidistantly cooled according to the shape of the mold, free design of a cooling path is realized, the cooling effect is improved, due to the fact that the whole stainless steel pipe fittings are bent, so that the problem of mold leakage is avoided, complete integrated casting is achieved, and the manufacturing cost is low.

Description

technical field [0001] The invention belongs to the technical field of casting, and relates to a casting method of a stainless steel water-cooled pipe embedded mold. Background technique [0002] Aluminum alloy car seat sponge mold is a common mold for the production of car seat sponge. During the foaming production process of car seat sponge, the mold used needs to be continuously water-cooled and kept at a constant temperature. In the past, the water cooling of the mold needed to be cooled by the way of mold drilling. This method has high cost and poor effect. [0003] Patent document 1 (CN210125723U) mold water-cooling combination kit includes a support base plate, a base plate is arranged above the support base plate, several steel pipes are arranged above the base plate, and sidewalls are arranged on the left and right sides of several steel pipes The water channel, the two side water channels and the outer side of the bottom plate are provided with a heat preservati...
