Embodiment 1

[0035] Please refer to Figure 1 to Figure 4 As shown, this embodiment provides a sand core installation structure for a vehicle box, including an upper mold 1, a front side mold 2, a rear side mold 3, a left side mold 4, a right side mold 5, and a lower mold 6 and the metal base 7 arranged on the lower mold 6, the metal base 7 is provided with a shunt hole 8, the material of the metal base 7 is a metal part resistant to high temperature and high pressure, preferably H13 mold steel, which has high structural strength and can stably support other sand molds Compared with the traditional sand mold base, it has better support stability, and it is not easy to be washed by aluminum water for a long time at high temperature, which will cause the base sand to fall off easily.

[0036] Please combine figure 1 and figure 2 As shown, the sand core structure includes a main sand core 9, a water channel sand core 10, a small water channel sand core 11, a cross sand core 12 and a lap sa...

Embodiment 2

[0047] This embodiment provides an installation method for the above-mentioned vehicle box sand core installation structure, and the specific installation steps are as follows:

[0048] Step (a): Use a resin adhesive to bond the bent portion 111 at the lower end of the small channel sand core 11 to the main sand core 9 for positioning; and use the first core head boss at the upper end of the small channel sand core 11 to insert Positioning is carried out in the first embedding groove on the upper end of the sand core 9; the height of the first core head boss is 19mm, and the depth of the first embedding groove is 14mm, so that after positioning, it can effectively ensure that the core body of the small channel sand core 11 is in line with the main body. The distance between the sand cores 9 is 5mm; and the positioning distance between the upper and lower ends of the small channel sand core 11 and the main sand core 9 is 340mm; this structural design is based on the design of th...

Abstract

The invention discloses a sand core mounting structure of a box for an automobile and a mounting method thereof, and relates to the technical field of sand core manufacturing. The sand core mounting structure of the box for the automobile and the mounting method thereof solve the circumstances that an existing split sand core structure is unstable in positioning, and sand cores are easily cracked,staggered and displaced after being assembled. The sand core mounting structure comprises a box die, and a metal base which is arranged on a lower die, wherein the sand cores are sequentially assembled on the metal base. The mounting method comprises the following sequential steps: positioning a small water channel sand core and a main sand core; closing a die at the rear side, and mounting a lugsand core; lapping a cross and core in a flow distribution hole; mounting the main sand core on the cross sand core; positioning a water channel sand core to the metal base and the main sand core; closing the die; and detecting whether the sand cores are subjected to cracking, staggering and displacing. According to the abovementioned technical scheme, the sand core mounting structure of the boxfor the automobile and the mounting method thereof, the sand core positioning and mounting stability can be effectively improved; the mounting is simple and quick; the positioning is accurate; in addition, the air exhausting effect of the split sand core structure in the box casting process can be completed.

Description

technical field [0001] The invention relates to the technical field of sand core manufacturing, and more specifically relates to a sand core installation structure and an installation method of a vehicle box. Background technique [0002] As the emission control of automobile exhaust in various countries in the world is becoming more and more stringent, the casting upgrade of the exhaust gas treatment box for existing vehicles is an inevitable product. Due to the high efficiency and power requirements of automotive engines in the market, the company focused on improving the fluidity of the metal liquid in the cavity when developing the casting exhaust gas treatment box, and continuously improved the filling materials, metal molds and sand cores. , Customized special casting equipment for vehicles. [0003] After research and development, the vehicle exhaust gas treatment box adopts a semi-sand low-pressure casting process. The sand core is the material used to manufacture t...
