CN202106491U - Compound die for rubber corrugated tubes used on rolling stock - Google Patents

Abstract

A compound die for rubber corrugated tubes used on rolling stock comprises die cores (1), an upper die block (2), an upper die frame (3), a lower die frame (4) and a lower die block (5), wherein the upper die block (2) has the same structure as the lower die block (5); at least two corrugated grooves (6) are formed on the lower die block (5); the upper die frame (3) is embedded in the upper die block (2); the lower die frame (4) is embedded in the lower die block (5); the upper die block (2) and the lower die block (5) are aligned with and attached to each other; corresponding upper and lower corrugated grooves form cavities; and the mould core are positioned in the cavities. The compound die can be opened or closed automatically, so as to reduce the labor intensity; and two or more sets of mould cores can be adopted for alternate use, so as to satisfy the production continuity and improve the production efficiency.

Description

The compound die of used for rolling stock rubber bellows

Technical field

The utility model relates to field of track traffic, specifically, relates to a kind of compound die of used for rolling stock rubber bellows, be on the EMUs one type of protection with the production mould of rubber bellows.

Background technology

At present, mainly there is disadvantage in protection with the production mould of rubber bellows on rolling stock and the EMUs: 1, product is relatively large, and the mode of production of taking is the production of single chamber or two chamber moulds, and mode of operation is the manual equalization of total man worker; Automaticity during 2, because of the making moulding is low, and the probability that causes artificial defective work to produce is bigger; 3, single chamber or two chamber moulds are produced, and the formed product time is longer, and production efficiency is low; 4, core rod is a cover, go into behind the mould moulding during this period of time in, the operative employee can only wait for by equipment, can not do other work, the utilization rate of working time is low.

Summary of the invention

The purpose of the utility model is the deficiency that overcomes prior art, provide a kind of production efficiency high, and can reduce the compound die of the used for rolling stock rubber bellows of operator's labour intensity.

The technical scheme that realizes above-mentioned purpose is: a kind of compound die of used for rolling stock rubber bellows; By core rod, upper module, go up framed, low mold frame and lower module is formed, upper module is identical with the lower module structure, has at least two wave grooves on the lower module; Go up framed being inlaid in the upper module; Low mold frame is inlaid in the lower module, and the upper and lower wave groove that upper module and lower module are involutory and corresponding forms die cavity, and core rod is positioned at this die cavity.

After adopting technique scheme, upper module is connected with the equipment upper flat plate, upward framedly hangs mold mechanism with its upper side and is connected, and can in the vertical direction certain limit, move, and flat board is connected under lower module and the equipment.Low mold frame can move horizontally in company with following dull and stereotyped the generation, and can also in the vertical direction certain limit, move under the effect of ejecting mechanism, and core rod is embedded in the plural at least die cavity of the corresponding wave groove formation in the involutory back of upper and lower module.Through above-mentioned connection, can realize the automatic folding of mould, reduce labour intensity, can adopt two covers or the above core rod of two covers to be used alternatingly, satisfy the continuity of producing, thereby can increase substantially production efficiency.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.

Shown in Fig. 1 ~ 6, a kind of compound die of used for rolling stock rubber bellows is by core rod 1, upper module 2, go up framed 3, low mold frame 4 and lower module 5 is formed; Upper module 2 is identical with lower module 5 structures; Have at least two wave grooves 6 on the lower module 5, go up framed 3 and be inlaid in the upper module 2, low mold frame 4 is inlaid in the lower module 5; Upper module 2 forms die cavity with lower module 5 involutory and corresponding upper and lower wave grooves 6, and core rod 1 is positioned at this die cavity.

The core rod 1 of the utility model can be realized two covers or the above continued operation of two covers; And through with being connected of equipment; Realize automation mechanized operation to a great extent, reduce Manufacturing Worker's labour intensity, raise labour productivity; And after reducing artificial execution action, can improve the quality of products and reduce damage to mould.

Claims (1)

1. the compound die of a used for rolling stock rubber bellows; Form by core rod (1), upper module (2), last framed (3), low mold frame (4) and lower module (5); It is characterized in that: upper module (2) is identical with lower module (5) structure; Have at least two wave grooves (6) on the lower module (5), go up framed (3) and be inlaid in the upper module (2), low mold frame (4) is inlaid in the lower module (5); The upper and lower wave groove (6) that upper module (2) and lower module (5) are involutory and corresponding forms die cavity, and core rod (1) is positioned at this die cavity.
