Description

Technical Field

[0001] The utility model belongs to the field of glass bottle preparation molds, in particular to a mold structure for preventing a glass bottle body from being deformed. Background Art

[0002] In the manufacturing process of glass bottles, the molten glass needs to be injected into the molding mold to make the glass bottle initially formed and then cooled, and then put into the mold for blow molding. The molding process of glass bottles is a gradual cooling process, and appropriate cooling of the mold is an important part of molding control. Generally, glass products have a thick bottom, so during molding, the thick bottom glass material will cause uneven cold shrinkage, and then the product will be deformed, resulting in poor quality of the glass bottle.

[0003] The Chinese patent document with publication number CN210176715U discloses a glass bottle forming mold used in the glass bottle blowing process. By additionally setting a plurality of exhaust grooves connected to the outermost circle vertical holes on the outer peripheral surface of the lower part of the mold, the heat dissipation area of ​​the lower part of the mold can be increased and the exhaust path of the lower hot air flow can be shortened while ensuring the mold is stable and strong, thereby making the heat dissipation and cooling effect of the lower part of the mold significantly greater than that of the upper part of the mold, which is well consistent with the characteristic that the temperature of the lower half of the mold is usually higher than that of the upper part, so that the upper and lower parts of the molding mold can be cooled to the target temperature at the same time, shortening the cooling cycle, and improving production speed and manufacturing efficiency.

[0004] In order to increase the heat dissipation effect of the lower part of the mold in the above patent solution, the heat dissipation area is increased. However, the faster the heat dissipation is, the better. Instead, it is necessary to ensure that the upper and lower parts of the mold are cooled to the target temperature at the same time. This also requires that the heat dissipation area of ​​the lower part of the mold is within a reasonable range. However, the calculation of the heat dissipation area itself is very complicated, and the calculated heat dissipation area is also easily affected by the external environment or processing materials, resulting in uneven heat dissipation of the upper and lower parts, affecting the appearance of the product. Trial-producing multiple molds will increase costs and time. Utility Model Content

[0005] In order to overcome the problem in the prior art that when the product is formed, the bottom glass of the product is relatively thick and the heat dissipation is slow, which will cause deformation after demolding, while it is not easy to increase the heat dissipation area of ​​the lower part of the mold; one purpose of the utility model is to provide a mold structure that prevents the deformation of the glass bottle body, by arranging a detachable heat dissipation component at the lower part of the mold, replacing the heat dissipation components with different heat dissipation areas to trial-produce glass bottles for comparison, and obtaining the most suitable heat dissipation component.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a mold structure for preventing a glass bottle from deforming, comprising a bottle bottom mold and two bottle body half molds; a cavity is arranged on the bottle body half mold; the two cavities and the upper end of the bottle bottom mold constitute a molding cavity of the glass bottle; a concave ring is molded on the outer wall of the bottle body half mold near the bottom of the glass bottle; a heat dissipation component is detachably connected to the concave ring; the heat dissipation component comprises an arc-shaped plate detachably connected to the concave ring and a plurality of heat dissipation fins uniformly molded on the outer wall of the arc-shaped plate; the inner wall of the arc-shaped plate is tightly against the semicircular outer wall of the concave ring; the outer contour radius of the heat dissipation fin is smaller than the outer contour radius of the bottle body half mold.

[0007] Optionally, the heat sink is an arc-shaped sheet coaxially arranged with the arc-shaped plate; a plurality of the arc-shaped sheets are evenly arranged along the axial direction of the arc-shaped plate.

[0008] Optionally, the heat sink is a plate arranged along the axial direction of the arc-shaped plate; a plurality of the plates are evenly arranged along the circumference of the arc-shaped plate.

[0009] Specifically, the numbers of the heat sinks in different heat dissipation components are different.

[0010] Specifically, the thicknesses of the heat sinks in different heat dissipation components are different.

[0011] Preferably, heat-conductive silica gel is provided between the arc-shaped plate and the semicircular outer wall of the concave ring.

[0012] Furthermore, a plurality of evenly distributed studs are arranged on the arc-shaped outer wall of the concave ring along the radial direction of the concave ring; a plurality of bosses are formed on the arc-shaped plate and are respectively arranged coaxially with the studs; screw holes are formed on the bosses and pass through the bosses; the studs pass through the screw holes; and screws are detachably connected to the studs.

[0013] Preferably, a plurality of evenly distributed heat dissipation cavities are formed at the lower end of the bottle bottom mold; the heat dissipation of the heat dissipation cavities is less than the difference between the heat dissipation of the lower part and the upper part of the mold.

[0014] Specifically, a plurality of heat dissipation rings with gradually increasing radii are formed in the bottle body half mold; the heat dissipation rings include a plurality of longitudinally arranged heat dissipation tubes evenly distributed along the circumferential direction; and the concave ring is connected to the heat dissipation tube located at the outermost side.

[0015] Furthermore, at least one heat dissipation component is installed in the concave ring.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The heat dissipation component at the bottom of the bottle half mold is detachable. Glass bottles can be trial-produced by replacing heat dissipation components of different models, and the best heat dissipation component can be obtained after comparison, thereby ensuring the qualified rate of glass bottles;

[0018] 2. The heat dissipation components can be reused, and heat dissipation components of different models can be installed on other molds with different molding cavities, thereby reducing the mold processing cost. BRIEF DESCRIPTION OF THE DRAWINGS
