Glassware mould fixture

Abstract

A glassware mould fixture belongs to the technical field of glassware moulds, which comprises a base, pivot shafts, a first fixture half mould and a second fixture half mould, and is characterized in that the surface of the base, which corresponds to the first and the second fixture half moulds, is provided with a group of base splice pieces, wherein the surface of one side of a first ware half mould bottom wall of a first ware half mould cavity, which corresponds to the base, is provided with first half mould splice pieces, the surface of one side of a second ware half mould bottom wall of asecond ware half mould cavity, which corresponds to the base, is provided with second half mould splice pieces, the first and the second half mould splice pieces are matched with the base splice pieces, a cylindrical boss is formed at the center of the upward surface of the base, a chip groove is arranged on the cylindrical boss, one group of the base splice pieces are arranged around the cylindrical boss, and chip gaps are left among the base splice pieces, and are communicated with the chip groove, and are further communicated with the outside. The glassware mould fixture has the advantagesof prolonging the service lives of the base, the first and the second fixture half moulds, conveniently cleaning, improving the shaping efficiency, and protecting a first, a second and a third pivot shaft bases.

Description

technical field [0001] The invention belongs to the technical field of glass moulds, in particular to a glassware mold fixture. Background technique [0002] As known to those skilled in the art, in the process of manufacturing (pressing) glassware such as glasses (including glasses with handles and glasses without handles), stirrer vessels, glass jugs, etc., due to the The mold is a two-opening mold structure, that is, a double-opening mold structure, so it cannot be directly installed on the machine. It must be installed on the glassware processing machine by the vessel mold fixture as the vessel mold carrier and a pair of vessel mold halves. The structure of the utensil mold fixture is composed of a base and a pair of jig halves of the same shape that are coaxially pivoted (also called hinged) on the base (the industry is accustomed to call it a clamp). When using a pair of utensils The half-molds are detachably arranged on a pair of clamp half-molds, and the opening and...

Problems solved by technology

[0003] The above clamp half-molds have the following deficiencies in the actual use process: First, the service life is short and the scrapping frequency is high, because a pair of clamp half-molds are opened and closed once every time a glassware is pressed, that is, every time a glassware is formed, so, The bottom surface of the fixture half mold and the surface of the base mold frequently rub against each other, causing both to be damaged and must be replaced in time; second, the stagnation phenomenon is serious, and even damages the surface of the base and the bottom surface of the fixture half mold. In the process, the flash at the seam of the glass product is easy to fall to the surface of the base, so when the clamp half is opened and closed, the glass slag on the base will enter between the bottom surface of the clamp half and the surface of the base, thus damaging the clamp half. The bottom surface of the mold and the surface of the base are damaged; the third is that the cooling speed of the jig half mold is slow, which affects the improvement of forming efficiency, which in turn affects the output per unit time; the fourth is the pivot shaft used to set the pivot shaft on the pivot shaft The service life of the seat is short, because during the opening and closing process of the jig halves, the pivoting shaft seat also rubs frequently, and as the degree of friction increases, the opening and closing effect of a pair of jig halves gradually decreases, unless the jig halves and the base Whole waste

[0004] Therefore, how to reasonably extend the service life of the container mold fixture has become a common concern of glassware manufacturers and glass mold (vessel mold) manufacturers and a technical problem that needs to be solved urgently. The problem has also been paid attention to for a long time, and literature searches have also been carried out. However, there is no enlightenment aimed at solving the above problems in the published patent and non-patent literature.
