Fig. 1 shows a cross-sectional view of a first mold half 1 in a prototype mold according to the utility model. Fig. 2 shows a cross-sectional view of the second mold half 2 in the prototype mold according to the utility model. The shape structure of the first half die 1 is mostly the same as that of the second half die 2, wherein the first half die 1 is a female die, the second half die 2 is a male die, the first half die 1 and the second half die 2 have a die matching surface 3, and the first half die 1 and the second half die 2 are different in that the second half die 2 is provided with a positioning boss 10 on the die matching surface 3, the first half die 1 is provided with a positioning groove 9 on the die matching surface 3, the positioning boss 10 and the positioning groove 9 are matched in shape and arranged oppositely, the positioning groove 9 is a trapezoidal groove, two inclined surfaces of the trapezoidal groove have good positioning accuracy, the accuracy of the assembled prototype die can be improved, and the assembled prototype die is as shown in fig. 3.

The upper half parts of the first half mould 1 and the second half mould 2 are cavities 4 for forming the glass bottle prototypes, and the cavities 4 are a top part 41, a waist part 42, a shoulder part 43 and a bottom part 44 from top to bottom in sequence. In this embodiment, the diameter of the top 41 of the cavity 4 is 36 mm, the diameter of the waist 42 is 32 mm, the diameter of the shoulder 43 is 33 mm, the diameter of the bottom 44 is 25 mm, and the linear distance from the top 41 to the shoulder 43 of the cavity 4 is 81 mm, and the angle between the vertical line and the line connecting the top 41 to the shoulder 43 of the cavity 4 is about 1.5 degrees according to the trigonometric function calculation formula. If the included angle is larger than 1.5 degrees, when the glass material liquid passes through the waist-closing part 42, the friction force of the cavity 4 to the glass material liquid and the viscous force of the glass material liquid, the falling resistance of the material liquid is increased, so that the heat release is uneven, the thickness of the glass wall is uneven, and the defect that the shoulder 43 of the finally formed glass bottle is too thin occurs. In order to avoid the above phenomenon, the diameter of the waist-collecting part 42 should be increased properly, so that the included angle between the vertical line and the connecting line of the top part 41 of the cavity 4 to the waist-collecting part 42 is smaller than 1.5 degrees, so that the material liquid can be smoothly discharged, and the wall thickness of the formed glass bottle is uniform.

The lower half parts of the first half mould 1 and the second half mould 2 are die positioning grooves 6 for installing a die. Because glass bottle body is in the forming process, glass feed liquid is pushed into the entry mould by atmospheric pressure, most glass feed liquid is piled up at the bottom 44 of die cavity 4, consequently, die joint face 3 is close to bottom 44 and has seted up the first exhaust groove 7 of horizontal setting at die cavity 4, in order to discharge gas as far as possible when glass bottle rudiment shaping, avoid forming the bubble in glass, consequently, first exhaust groove 7 transversely extends to the outside of die cavity 4 from the inboard of die cavity 4, wherein 0.1 millimeter deep recess is processed through the mode of milling to first exhaust groove 7, second exhaust groove 8 has been seted up at the die joint face 3 in the edge, 0.5 millimeter deep recess is processed through the mode of milling to second exhaust groove 8 also, first exhaust groove 7 and second exhaust groove 8 communicate. Through the exhaust grooves of two different depths, the joint line of the prototype is guaranteed to be small enough and fine enough, exhaust can be smooth, and the prototype is not easy to be blocked by overflowing material liquid.

The blank mold is typically cast from cast iron, which is an alloy of iron and carbon, usually doped with small amounts of elements such as silicon, sulfur, phosphorus and manganese. Cast iron can be cast into complex shapes and is also easy to machine, but its mechanical properties are poor, such as hardness. In the embodiment, the edge of the cavity 4 is easy to crack due to the large punching force of the punch, and the generated cracks can directly influence the quality of finished glass. In order to prolong the service life of the die, the outer edges of the top part 41 and the bottom part 44 of the die cavity 4 are provided with the hardened wear-resistant layers 5, and the hardness and the wear resistance of the outer edges are increased by arranging the hardened wear-resistant layers 5, so that the cracking is reduced. Specifically, the hardened wear-resistant layer 5 is formed by spray welding at the edge, alloy powder is adopted as filler metal in the spray welding, the powder material is vertically sprayed downwards to the surface at the edge of the cavity 4 by heating and accelerating the powder material, the spraying time is 25 minutes, the powder material is melted on the surface, and a spray welding layer with a sector-shaped section and a depth of 2 millimeters is formed. The powder material can be nickel-based alloy powder, the nickel-based alloy powder has good binding capacity with cast iron after being melted, the Rockwell hardness of a spray welding layer formed by the nickel-based alloy powder and the cast iron can reach 40-50HRC, the Rockwell hardness is obviously higher than that of the cast iron, and the wear resistance is also obviously improved.
