[0015] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0017] like Figure 1 to Figure 2 As shown, a casting model structure of a clamp body with thick structures on both sides of a cylinder head includes a riser 1, a water inlet channel A2, a bridge insulation block 3, a water inlet channel B4, a cylinder bore insulation block 5 and a casting 6. An injection channel connected to the molten iron input end of an external pouring system is provided at the bottom of the riser 1, and a first output end and a second output end are provided on the riser 1. The first output end of the riser 1 is connected to the casting 6, and the second output end of the riser 1 is connected to the water inlet channel A2. The other end of the water inlet channel A2 is connected to the input end of the bridge insulation block 3, the output end of the bridge insulation block 3 is connected to the water inlet channel B4, and the other end of the water inlet channel B4 is connected to the cylinder bore insulation block 5. The bridge insulation block 3 and the cylinder bore insulation block 5 are both fitted with the casting 6.

[0018] The riser 1 comprises a sphere 11 and a truncated cone 12 connected to the sphere 11 , and the first output end and the second output end are both located on the sphere 11 .

[0019] The water inlet channel A2 includes two connected rectangular flow guide pipes, one end of the two connected flow guide pipes is connected to the second output end of the riser 1, and the other end is connected to the bridge insulation block 3.

[0020] The outer shape of the bridge heat-insulating block 3 is a regular quadrangular pyramid.

[0021] The water inlet channel B4 has a rectangular shape.

[0022] The cylinder hole insulation block 5 includes a connecting section 51 with a semi-cylindrical shape and an insulation section 52 with a cylindrical shape. The connecting section 51 is connected to the insulation section 52 , and the water inlet channel B4 is connected to the connecting section 51 .

[0023] The heat-insulating section 52 is partially located inside the cylinder bore of the casting 6 .

[0024] When the present invention is working, a pair of templates installed with the present invention are respectively printed out sand molds during the molding process, and each sand mold molds a corresponding mold cavity. After that, the two sand molds are molded together, and molten iron is poured. The molten iron reaches the riser 1 on the lower template through the pouring channel of the pouring system, enters the pouring channel of the casting 6 through the first output end of the riser 1 for pouring, and forms a casting product. The molten iron enters the water inlet channel A2 through the second output end of the riser 1, and then enters the bridge insulation block 3 and the water inlet channel B4 in sequence, and finally reaches the cylinder hole insulation block 5. The present invention has a simple structural design, is easy to process and manufacture, and occupies little template space. The riser 1 is both a shrinkage compensation body and a drainage structure. The bridge insulation block and the cylinder hole insulation block can combine the existing hot spots into one hot spot, so that the riser 1 can be smoothly compensated for shrinkage and reduce product shrinkage defects. The present invention has a simple structural design, is easy to process and manufacture, and occupies little template space.

[0025] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
