Description
Technical Field
The invention belongs to the technical field of glass molds, and particularly relates to a primary mold structure of a glass mold.
Background
As known in the art, it is common practice to use a blow-and-blow method to manufacture glass containers such as beer bottles, red wine bottles, soda bottles, sparkling wine bottles, various condiments bottles, and daily cosmetics bottles, to introduce a molten glass melt into the preform, blow-mold the preform into the preform to form a glass container preform (commonly known as a preform in the industry), and then to transfer the preform into the mold by a manipulator to blow mold, thereby obtaining a finished glass container.
Further, as known in the art, the primary mold is formed as a forming mold and needs to be opened and closed repeatedly during actual use. In particular, the primary mold is also composed of a pair of mold halves that are mated face to face with each other and are identical in structure, and no information has been found in the middle-outer patent literature or in the non-patent literature as to whether the primary mold structure in the form of the two mold halves is reasonably questioned for a long time. However, the applicant believes that the rationality of the primary mould structure in the form of two half moulds is not questioned, and is mainly influenced by long-term acceptance and does not indicate that the primary mould structure in the form of two half moulds does not present a substantial problem. Extensive data accumulated and generalized categorization during glass mold manufacturing has long been shown by the applicant: with the current technical equipment and the manufacturing level of glass containers, the design of the forming die into a two-half structure is still an essential means, but the design of the primary die into a structural form which is impossible to realize and can get rid of the two half is completely realizable beyond the ordinary thinking of people. Because the primary mold in the two-half mold structure has the following technical problems: firstly, because the glass container needs to be opened and closed in a use state, the manufacturing efficiency expected by a glass container manufacturer is greatly affected; secondly, the primary mould is designed into two half moulds and needs to be frequently opened and closed in the use process, so that the roundness of the glass container blank blown in the primary mould, namely the glass container blank, is difficult to ensure, and finally the quality of the glass container is influenced; thirdly, as the primary mould is of a two-half mould structure, the matching condition of the two half moulds is considered, and the matching precision of the two half moulds and the tightness between the matching surfaces are considered; fourth, because the primary mould is of a two-half mould structure, the processing difficulty is relatively high, the processing cost is high and the processing time is long, so that the method is not beneficial to reflecting economy and is difficult to meeting the quick delivery requirements of glass container manufacturers. In view of the foregoing, the applicant has devised and developed the solution to be described below.
