Embodiment Construction

[0010] Comparing with accompanying drawing 1 and accompanying drawing 2, a kind of manufacturing method of coupler integral core shooting mold of the present invention is that the sand core of coupler inner cavity adopts integral core shooting; Core box body 1 16 and core box body 2 12 made of cast iron are combined to form a core box body, which is placed on the core box positioning plate 27, with handles 21 on both sides, and two openings on the core box body. Sand injection port, one main injection port, one auxiliary injection port, the inner wall of the sand injection tube is lined with a sand injection bushing 15; at the same time, the injection head is designed as a special injection head 30, which is placed above the core box body and between the core box body There is an upper backing plate 14; under the core box body is a hydraulic ejector mechanism, including the core box bottom plate 4 below the core box body, the ejector rod 2 connected to it, the lower ejector pla...

Abstract

A technology for manufacturing the integral core shooting mould of the train coupler features that its core box is made up of antiwear cast iron through casting and has two openings for shooting core, its shooter is specially designed, multiple holes and two keys are used for positioning, its internal cavity is formed by movable blocks for easy demoulding, and said core box has air exhausting plug, blowing plate, tuyere and CO2 tube.

Description

technical field [0001] The invention relates to the technical field of unique coupling pieces for railway vehicles, in particular to the design and manufacture of an integral core-shooting mold for a coupler. Background technique [0002] The coupler is the most critical traction component in the operation of railway rolling stock. It connects and pulls each carriage and locomotive. Therefore, its quality directly determines the operating safety and operating efficiency of the rolling stock. The required performance indicators are specified in GB1725 and There are strict regulations and restrictions in GB / T2703-1996. In order to improve the casting quality of the coupler, various manufacturers have made various attempts in terms of technology and molds. But because the shape of the coupler is complex and asymmetrical, and the sand core weighs up to 65 kilograms, the manufacture of the mandrel still adopts the method of making and assembling the lower core in sections so far...
