Description
Technical Field
The application belongs to the technical field of glass molds, and particularly relates to a combined mold for processing a glass container.
Background
The above-mentioned combination mold includes a combination primary mold and a combination forming mold. The molds used for processing glass containers (such as beer bottles, red wine bottles, soda bottles, daily life cosmetics bottles, seasoning bottles, and various beverage bottles, etc.) are generally of a two-half mold structure symmetrical to each other, and for this purpose, see, for example, chinese patent application publication nos. CN101298355A (mold for making glass containers), CN101298356a (mold for making glass containers), CN101298357a (mold for processing glass containers), CN101298358A (mold for processing glass containers), CN101298359a (mold for processing glass containers), CN101941791a (mold for making glass containers for bottles and cans), grant publication No. CN102515471B (mold for making glass containers for bottles and cans), and US2006/0213632A1 (glass molding mold), etc.
The glass mold having the symmetrical two-mold half structure as exemplified above is not limited to the above, and can satisfy the requirements for processing glass containers such as bottles and cans, but is a single-cavity mold, that is, only one glass container at a time can be processed, and thus the processing efficiency of the glass container is greatly affected. The improvement of the machine speed of the glass container processing machine can correspondingly improve the processing efficiency of the glass container, but the requirements on the materials, heat dissipation and peripheral cooling measures of the glass mold are often more severe, so that on one hand, the cost of the glass mold can be obviously improved, and on the other hand, the price of the glass container can be increased, and the market competitiveness is influenced.
In terms of the current manufacturing equipment and manufacturing skills for glass molds, processing single-cavity glass molds in duplicate form into dual-cavity or even three-cavity molds does not create any obstacle and is objectively easy to think of. But the heat dissipation problem is pronounced after the mold cavity is increased, for example, to a reasonable number of three mold cavities to form a composite mold. Perhaps due to the aforementioned heat dissipation factors, technical information about the effective cooling of a combination mold, particularly for a combination mold, is not seen in both the middle and outer patent and non-patent documents disclosed so far.
Although the "liquid cooling method for glassware mold" recommended by CN1286746C and the "glassware mold with cooling device and method for cooling glassware mold" provided by CN101137584a can play a good role in cooling the glassware mold, these two patents are designed for single cavity mold, so that there is no technical teaching for the combined mold with multiple mold cavities. The technical solutions to be described below are created in this context.

In the present embodiment, the left longitudinal heat dissipation groove i 13a, the middle longitudinal heat dissipation groove ii 13b, and the right longitudinal heat dissipation groove iii 13c are each six and three long and three short. But is not limited by the present embodiment. Furthermore, from the illustration of fig. 5 and what has been described above in connection with the applicant, in particular in connection with the general knowledge, it can be undoubtedly determined that one of the pair of half-mould bodies 1 shown in fig. 5, i.e. the one on the right side of fig. 5, is a female mould and this female mould is also illustrated by fig. 1 to 3 and fig. 4, while the other of the pair of half-mould bodies 1, i.e. the one on the left side of the position state shown in fig. 5, is a male mould, the so-called female mould being referred to as "male mould": a flange matching groove is formed on the joint surface and along the height direction of the joint surface; the male die means: the joint surface is provided with a convex stage protruding from the joint surface along the height direction of the joint surface, the convex stage is matched with the convex stage matching groove, and the other combinations of the concave mold and the convex mold are identical, namely, the two half mold bodies 1 have the same structures except the convex stage matching groove and the convex stage, and the left, middle and right mold cavities 111, 112 and 113 are respectively arranged.
Referring to fig. 4 and referring to fig. 1, at the lower part of the half die body 1 in the height direction and at the position corresponding to between the left longitudinal radiating groove i 13a and the middle longitudinal radiating groove ii 13b and at the position corresponding to between the middle longitudinal radiating groove ii 13b and the right longitudinal radiating groove iii 13c, heat transfer cooling bars 14 are each provided at intervals from top to bottom in a state perpendicular to the thickness direction of the half die body 1, wherein the end of the heat transfer cooling bar 14 provided between the left longitudinal radiating groove i 13a and the middle longitudinal radiating groove ii 13b passes through the first middle longitudinal cooling water passage i 1242 toward the end of the die cavity 11, and the end of the heat transfer cooling bar 14 provided between the middle longitudinal radiating groove ii 13b and the right longitudinal radiating groove iii 13c passes through the second middle longitudinal cooling water passage ii 3 toward the end of the die cavity 11, and the end of the heat transfer cooling bar 14 facing away from the die cavity 11 is detected into the cooling bar cooling cavity 15 formed on the half die body 1.
