O-shaped ring die capable of being positioned

Abstract

The invention discloses an O-shaped ring die capable of being positioned, and belongs to the field of dies. The O-shaped ring die capable of being positioned comprises a lower die body and an upper die body, wherein the lower die body is provided with a plurality of cavities, and the upper die body is also provided with a plurality of cavities. A plurality of casting openings are drilled in the upper end of the upper die body. Cores are arranged in the cavities of the lower die body. Limiting grooves are drilled in the inner top surfaces of the cavities of the upper die body, and the cores arematched with the limiting grooves. Main sliding plates and pressing plates are separately arranged on the left side and the right side of the upper die body. The upper ends of the main sliding platesare fixedly connected with the lower ends of the pressing plates. A pair of main sliding grooves is drilled in the upper end of the lower die body. The lower ends of the main sliding plates are slidably connected into the main sliding grooves. Auxiliary sliding plates are arranged on the two sides of the main sliding plates. A plurality of auxiliary sliding grooves are drilled in the upper end ofthe lower die body. The lower ends of the auxiliary sliding plates are slidably connected into the auxiliary sliding plates. A pair of extension springs is fixedly connected between the upper end ofeach auxiliary sliding plate and the lower end of the corresponding pressing plate. According to the O-shaped ring die capable of being positioned, the lower die body and the upper die body can be tightly matched, positioning is stable, looseness is avoided in the using process, and the casting process can proceed smoothly.

Description

technical field [0001] The invention relates to the field of molds, and more specifically relates to a positionable O-ring mold. Background technique [0002] In the mold industry, various molds and tools are used for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. The O-ring mold is a kind of mold, but the existing O-ring mold The structure of the ring mold is relatively simple. The existing O-ring mold is only positioned by four guide posts and guide sleeves, and needs to be fed with an aluminum feeder. [0003] The existing O-ring molds are prone to loosening and unstable positioning during matching and positioning, thereby affecting the casting process. Contents of the invention [0004] 1. Technical problems to be solved [0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a positionable O-ring mold, which can re...
