In view of fig. 1 to 4, the present application provides a glass cooling forming bottom mold, which specifically includes:
the lower die comprises a lower die 100, wherein a convex forming area 110 and a concave forming area 120 are arranged on the outer surface of the lower die 100, a concave cooling area 130 corresponding to the convex forming area 110 is arranged inside the lower die 100, a cooler 200 is correspondingly arranged in the concave cooling area 130, the cooler 200 comprises a main air outlet 210 and an auxiliary air outlet 220, the main air outlet 210 is aligned to the top of the concave cooling area 130 and used for air blowing cooling, and the auxiliary air outlet 220 is used for air blowing cooling to the concave cooling area 130.
Through the technical scheme, the cooler 200 is provided with the main air outlet 210 and the auxiliary air outlet 220, the main air outlet 210 is aligned to the top of the concave cooling area 130 for air cooling, the core with the highest temperature is aimed at for cooling, the auxiliary air outlet 220 is used for air cooling to the whole area of the concave cooling area 130, the temperature of the periphery of the core with the highest temperature is reduced, the temperature of the area with the highest temperature is prevented from being excessively concentrated, and therefore the purpose of uniform cooling is achieved, the temperature change of the bottom of the glass bottle is more moderate in the final forming process of the bottle bottom of the whole glass bottle, and the problem of forming quality caused by the excessively large temperature difference is avoided.
Further, in some of the embodiments, the side of the recessed cooling area 130 is disposed to be inclined inward, and the auxiliary air outlet 220 is disposed along the side of the recessed cooling area 130 toward the top of the recessed cooling area 130 for blowing air cooling along the side of the recessed cooling area 130 toward the top of the recessed cooling area 130.
By the above technical solution, when the auxiliary air outlet 220 is used for blowing air for cooling, the air for cooling is blown to the top position of the concave cooling area 130 along the side surface of the concave cooling area 130 which is obliquely arranged inwards, that is, the air for cooling is mainly cooled at the top position of the concave cooling area 130, the top position of the concave cooling area 130 corresponds to the top position of the convex forming area 110, and the temperature of the top position is highest, so that the air blown out by the auxiliary air outlet 220 is mainly cooled at the top position of the concave cooling area 130, and at the same time, the blown air flows along the side surface of the concave cooling area 130, so that the air exchanges heat with the side surface of the convex forming area 110 at the side surface of the concave cooling area 130, thereby achieving the purpose of cooling, and the air flows only along the side surface, so that the cooling effect is not strong, the air is arranged because the temperature of the top area is highest in the convex forming area 110, and the air outlet 220 blows air at the farther away from the top area, the temperature is lower, the speed is faster from the center, the speed of natural cooling is higher, so that the air outlet 220 blows air at the side surface of the bottle, and the bottle bottom of the bottle is more uniformly cooled, thereby being beneficial to the bottle, and the bottle bottom of the bottle is more uniformly cooled, and the bottle is more uniformly distributed.
In which the side of the concave cooling area 130 is inclined inward, so that when the auxiliary air outlet 220 is used for blowing air for cooling, the air for cooling is guided to the top of the concave cooling area 130, thereby better cooling the top.
Wherein the sides of the convex forming region 110 are also inclined inward, and the purpose of this arrangement is determined by the product of the glass bottle, and the stress concentration at the bottom of the glass bottle can be reduced.
In some embodiments, the side surfaces of the concave cooling region 130 and the side surfaces of the convex forming regions 110 are arranged in parallel at equal intervals, that is, the side wall thickness between the concave cooling region 130 and the convex forming regions 110 is equal, the heat transfer efficiency is the same under the condition that the material is unchanged, as the gas for cooling is intensively blown to the concave cooling region 130, the cooling effect is better when the gas is closer to the top of the concave cooling region 130, and the cooling effect is worse when the gas is far away from the top of the concave cooling region 130, so that the glass bottle can adapt to the condition that the center temperature of the convex forming regions 110 is the highest and the temperature is lower when the gas is far away from the center, and the bottom of the glass bottle can be cooled more uniformly in the cooling forming process, and the temperature difference of the bottom can be reduced.
In other embodiments, the side wall thickness between the concave cooling region 130 and the convex forming region 110 is not equal, that is, the inclination angle of the side of the concave cooling region 130 is not equal to the inclination angle of the side of the convex forming region 110, and the side of the convex forming region 110 is closer to the concave forming region 120, so that the cooling effect is worse at the position on the convex forming region 110 closer to the concave forming region 120, and since the side is farther from the center of the convex forming region 110, the temperature itself is lower, the cooling effect is reduced by making the wall thickness of the side wall thicker, the temperature of the side wall can be closer to the temperature at the center of the convex forming region 110, thereby reducing the overall temperature difference and being more beneficial to temperature control.
Further, in some embodiments, the auxiliary air outlets 220 are provided in plural, and the plural auxiliary air outlets 220 are uniformly distributed around the main air outlet 210.
Through above-mentioned technical scheme, be provided with a plurality of supplementary air outlets 220 that set up around main air outlet 210 evenly distributed, when actually cooling down, can select the use quantity and the service position of supplementary air outlet 220 according to particular case, can have bigger control allowance, be favorable to realizing the temperature control to the glass bottle cooling forming in-process.
