Description

Technical Field

[0001] The utility model belongs to the field of molten iron casting, and in particular relates to an anti-cracking ground mold. Background Art

[0002] The molten iron ladle filled with liquid ferroalloy is continuously discharged through the tap hole at the bottom by a bridge crane or a ladle tilting device, and injected into a detachable ground mold through a flow chute. The alloy solidifies into an ingot in the ground mold. After its temperature cools down to a certain level naturally (or with the aid of water spray), it is transported to a cooling trolley by a crane for water cooling, and the ferroalloy can be demoulded.

[0003] After multiple pourings, the existing ground molds are easily cracked due to the erosion of ferroalloys, high-temperature corrosion, thermal shock and gravity. In addition, the splicing degree of adjacent ground molds is not high, and the laying efficiency of the ground mold is low. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-cracking floor mold, which can effectively improve the structural strength of the floor mold, extend its service life, and effectively improve the overall laying efficiency of the floor mold.

[0005] To achieve the above-mentioned purpose, the utility model provides an anti-cracking floor mold, including a floor mold body, a plurality of support columns are symmetrically arranged on both sides of the floor mold body, a rib is arranged on the upper surface of the floor mold body along the length direction, a lower extension part and an upper extension part for splicing are arranged at both ends of the floor mold body, a plurality of limit strips are arranged on the lower extension part along the width direction of the floor mold body, and a limit groove is arranged on the upper extension part corresponding to the limit strips, an end of the floor mold body close to the lower extension part is located above the lower extension part and a fixed positioning column is arranged, and a positioning splicing groove matching with the fixed positioning column is arranged at the other end of the floor mold body.

[0006] As a further solution of the utility model: the support column and the reinforced positioning column are both laid inside the ground mold body, and the support column is fitted under the reinforced positioning column.

[0007] As a further solution of the utility model: a suspension groove is provided on the support column.

[0008] As a further solution of the utility model: a high temperature resistant coating is sprayed on the upper surface of the floor mold body.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] The support and coordination of the support column and the fixed positioning column can effectively enhance the structural strength of the floor mold body, and the high temperature resistant coating sprayed on the surface can effectively extend the service life;

[0011] A limit strip is provided on the lower extension part, and a limit groove is provided on the upper extension part. Together with the protruding reinforcement positioning column at one end of the floor mold body and the corresponding reserved positioning splicing groove at the other end, the floor mold can be accurately positioned, spliced ​​and laid, while avoiding displacement caused by the impact during molten iron pouring. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In the figure: 1. floor mold body, 2. support column, 3. suspension groove, 4. lower extension part, 5. limit strip, 6. additional positioning column, 7. retaining edge, 8. high temperature resistant coating, 9. limit groove, 10. upper extension part, 11. positioning splicing groove. DETAILED DESCRIPTION

[0015] The utility model will be further described below in conjunction with the accompanying drawings.

[0016] like Figure 1 and Figure 2 As shown, the anti-cracking floor mold comprises a floor mold body 1, a plurality of support columns 2 are symmetrically arranged on both sides of the floor mold body 1, a retaining edge 7 is arranged on the upper surface of the floor mold body 1 along the length direction to form a casting cavity, and a lower extension part 4 and an upper extension part 10 are arranged at both ends of the floor mold body 1 to form a splicing fit, which can be spliced ​​and used as needed according to the size of the casting site, a plurality of limiting strips 5 are arranged on the lower extension part 4 along the width direction of the floor mold body 1, and a limiting groove 9 is arranged on the upper extension part 10 corresponding to the limiting strips 5, and one end of the floor mold body 1 close to the lower extension 4 is located at the lower extension part A reinforcing positioning column 6 is provided above the extension portion 4, and a positioning splicing groove 11 matching the reinforcing positioning column 6 is provided at the other end of the ground mold body 1. The reinforcing positioning column 6 runs through the entire ground mold body 1. The reinforcing positioning column 6 can be used to strengthen the structure of the ground mold body 1. At the same time, the reinforcing positioning column 6 and the positioning splicing groove 11 are limited in the width direction of the ground mold body 1, and the limiting groove 9 and the limiting strip 5 are used in the length direction of the ground mold body 1. This can make the laid ground mold more stable and will not cause displacement during the molten iron pouring process.

[0017] For the structural strength of the floor mold body 1 , further, the support columns 2 and the reinforcement positioning columns 6 are both laid inside the floor mold body 1 , and the support columns 2 are fitted under the reinforcement positioning columns 6 , so that a grid-like support structure is formed inside the floor mold body 1 .

[0018] During the process of laying the floor formwork body 1 , equipment such as a crane may be used to complete the process. In order to facilitate the lifting of the floor formwork body 1 , a suspension groove 3 is further provided on the support column 2 .

[0019] In order to enhance the high temperature resistance of the floor mold body 1 , a high temperature resistant coating 8 is sprayed on the upper surface of the floor mold body 1 to prevent the floor mold body 1 from being seriously damaged by the high temperature iron alloy.

[0020] When the utility model is actually used, according to the needs, after selecting a suitable paving position, the anti-cracking floor formwork is lifted and placed in sequence. During the paving process, the limit groove 9 is kept aligned with the limit strip 5, and the fixed positioning column 6 is aligned with the positioning splicing groove 11, and the paving is formed in one time.
