Positioning mold locking structure of centrifugal casting machine

Abstract

The invention discloses a positioning mold locking structure of a centrifugal casting machine. The positioning mold locking structure of the centrifugal casting machine comprises first driving mechanisms, first plates, first core shafts, upper molds, second core shafts, lower molds, positioning columns, clamping rings, locking units and second driving mechanisms. The first driving mechanisms are installed on a machine body of the centrifugal casting machine and connected with the first plates, the first core shafts are movably connected with the first plates, and the upper molds are connectedto the first core shafts. The lower molds are arranged below the upper molds at intervals and installed on the second core shafts, the second core shafts are rotatably connected with the machine body,and the second driving mechanisms are further arranged between the second core shafts and the machine body. The positioning columns are connected to the first core shafts, the clamping rings are connected to the lower molds or the second core shafts and provided with clamping holes, the positioning columns are used for being clamped to the clamping holes, and the locking units are used for keeping the positioning columns and the clamping rings fixedly connected. Through clamping of the positioning columns and the clamping rings, the upper molds and the lower molds are mechanically locked andopened, the production efficiency is greatly improved, and the hidden safety dangers of manual mold opening and locking are eliminated.

Description

technical field [0001] The invention relates to a centrifugal casting machine, in particular to a positioning and clamping structure of the centrifugal casting machine. Background technique [0002] MC nylon is also called cast nylon. Due to its good physical and chemical properties, its status in engineering plastics has risen rapidly and it has been gradually used in various industries. Its production process is similar to the metal centrifugal casting process, and it is usually produced by centrifugal casting machines. First preheat the upper mold and lower mold in the centrifugal casting machine and close the upper mold and lower mold, then directly inject raw materials into the preheated upper mold and lower mold of the nylon centrifugal casting machine, and then drive through the reducer The upper mold and the lower mold rotate and perform centrifugal motion, so that the raw materials undergo rapid polymerization reaction in the mold and solidify and form, and then the...
