Integrally casting technology of tire mold patterned ring basic model, silica gel, gypsum and aluminum ring

Abstract

The invention relates to an integral casting technology of a tire mold patterned ring basic model, silica gel, gypsum and an aluminum ring, which belongs to the semi-steel tire mold field. The technology comprises the following steps: 1.1 a basic model base is prepared to a basic tire shape , a whole circle is divided into eight equal parts, the external surface of the basic model base is milled a patterned surface; 1.2 the basic model is placed in a silica gel liner mold, then the regulated silica gel is injected between an inner wall of the silica gel liner mold and a cylindrical surface ofthe basic model; 1.3 the silica gel liner mold is opened after the silica gel in the silica gel liner mold is solidified, the formed silica gel is dismounted from the surface of the basic model; 1.4 the formed silica gel is placed in the silica gel liner mold, then secondary gypsum is injected in the silica gel; 1.5 a gypsum model is placed in a secondary drying furnace for heating and drying. The silica gel and gypsum model of the present invention are capable of realizing one-step forming, optimizing the technology step of the tire mold, reducing the production manufacture cost and decreasing workload and labor intensity of operators.

Description

technical field [0001] The overall casting process of tire mold pattern ring base mold, silica gel, gypsum, and aluminum ring belongs to the field of semi-steel tire molds, and specifically designs an integral core injection process for tire mold gypsum cores. Background technique [0002] At present, the processing of general-purpose tire molds is divided into two types: flexible molds and two-half molds. In the existing tire mold processing technology, the main feature is that the base mold, silica gel, primary gypsum and secondary gypsum are all processed into eight pieces on average, so there are the following defects: ① Since the base mold is processed into eight pieces, it is necessary to The processing and programming are programmed eight times, and the blank material of the base mold is wasteful, the processing volume is large, the corresponding workload is large, and the processing cycle is long; Not only is a large amount of silica gel wasted, but the processing a...

In the existing tire mold processing technology, the main feature is that the base mold, silica gel, primary gypsum and secondary gypsum are all processed into eight pieces on average, so there are the following defects: ① Since the base mold is processed into eight pieces, it is necessary to The processing and programming are programmed eight times, and the blank material of the base mold is wasteful, the processing volume is large, the corresponding workload is large, and the processing cycle is long; Not only is a large amount of silica gel wasted, but the processing accuracy cannot be guaranteed; ③The secondary gypsum processing is also divided into eight pieces, which also has the problem of heavy workload and waste of gypsum raw materials; Therefore, it is necessary to carry out two drying processes, one drying and two dryings. After drying, it is easy to deform. After the second drying, it is necessary to assemble the gypsum twice. The surface problem cannot guarantee the accuracy and concentricity after assembly, and increases the workload and labor intensity again

[0003] Therefore, the processing technology of this kind of tire mold is not ideal in the actual production process. The burden on it is poor in practicability
