Device for casting aluminum alloy tyre die

Abstract

The invention discloses a device for casting an aluminum alloy tyre die. The device comprises an outer steel die (1) and a gypsum casting mold (2) located at an inner side of the outer steel die (1). A casting cavity (3) is formed between the outer steel die (1) and the gypsum casting mold (2). A thin-wall pipe (4) is arranged at an outer side of an end surface of the gypsum casting mold (2). One end of the thin-wall pipe (4) is fixed to the end surface of the gypsum casting mold (2) and the other end of the thin-wall pipe (4) extends towards the casting cavity (3) along a length direction of the thin-wall pipe (4). Through the thin-wall pipe, the interior of a tyre die casted by the device is provided with needed air holes and thus a hole drilling process after tyre die casting is avoided; operation time and labor are reduced and a production cost is greatly reduced; in drilling, drill breaking and drill location errors are avoided; and a tyre die can be casted completely according to a construction drawing so that customer requirements are satisfied. The device has a simple structure and stable production quality and is suitable for popularization.

Description

technical field [0001] The invention relates to a tire mold manufacturing device, in particular to a time-saving, labor-saving, low-cost, and stable-quality aluminum alloy tire mold casting device. Background technique [0002] Existing tire molds belong to rubber molding molds, and the appearance and quality of tires depend on the appearance of tire molds, the fluidity of rubber materials and the quality of venting. To solve the above problems, in addition to improving the fluidity of the rubber in the compound formula, it is more important to set vent holes and vent grooves on the tire mold to facilitate the exhaust of the tire during the manufacturing process and prevent rubber shortage and gas. The occurrence of defects such as drums. Therefore tire mold must be provided with a lot of vent holes or vent grooves in the design process. [0003] For the vent holes of tire molds, the current tire mold industry generally adopts the method of manual or machine punching. Ta...

Problems solved by technology

Due to the large number of air holes in this drilling method, it is not only time-consuming and labor-intensive, but also has a high cost; at the same time, due to manual drilling or machine drilling, the drilling force cannot be accurately controlled, and the phenomenon of drill bits breaking occurs from time to time. And as a result, the position of the air hole and the appearance of the mold cannot be constructed completely according to the requirements of the drawing, and cannot meet the customer's requirements, resulting in the scrapping of the semi-finished tire mold
