Mold of railway vehicle coupler inner chamber integrated core horizontal parting cold shooting core box

Abstract

The invention relates to a mold of a railway vehicle coupler inner chamber integrated core horizontal parting cold shooting core box, which comprises a core box body, a sand shooting plate, an air blowing plate and a plunger tip mechanism and is characterized in that the core box body comprises an upper core box and a low core box and forms a horizontal-installed core box chamber; a left pulling block and a right pulling bock are arranged on both sides of the core box body; the front end of the core box body is provided with an empty pulling block; and the pulling blocks are respectively connected with a dynamic mechanism. The mold of the railway vehicle coupler inner chamber integrated core horizontal parting cold shooting core box has simple operation, high production efficiency, low scrap rate and long service life.

Description

technical field [0001] The invention relates to a core box mold, in particular to a cold shot core box mold with integral horizontal core in the coupler inner cavity of a railway vehicle. Background technique [0002] It is used to produce the integral sand core of the inner cavity of the coupler body casting of the railway vehicle. The material of the existing product sand core is generally sodium silicate sand or resin sand. The inner cavity sand core of the original coupler body casting is composed of two pieces (see figure 1 , 2 ), two sets of core boxes are required, the production method is manual core making, the material of the core box is cast aluminum, the strength of the sand core is low, the production efficiency is low, and defects are prone to occur at the joints. The service life of the mold is about 15,000 times. The utility model with the application number of 200620131318 discloses a supporting mold for a cold box core shooter, including a sand injection...
