Turntable vacuum moulding production line

Abstract

The invention relates to a turntable vacuum moulding production line which comprises a shakeout transfer trolley, an electromagnetic iron absorption mechanism, a pouring mechanism, box closing manipulators, a box returning motor roller way, a box opening space motor roller way and a box opening space. In the invention, multiple pairs of upper and lower box models are arranged in a circular automatic moulding ring respectively; the models are continuously subjected to coating, spraying, drying, empty box fastening, sand addition, compaction, smoothening and back film coating, wherein all operations can be automatically performed, except for the spraying which is manually operated. Two rapping box closing manipulators are arranged between two moulding rings so as to perform rapping, box turning and box closing on the lower and upper boxes respectively. The closed moulding boxes are continuously arranged in the pouring moulding ring and sequentially subjected to pouring, cooling and box opening, wherein manual pouring is adopted generally, and other processes can be realized automatically; and due to the automatic moulding line, the production efficiency is greatly improved, and the moulding of 20 models can be realized per hour.

Description

technical field

[0001] The invention relates to a casting machine, in particular to a turntable V-method molding production line. Background technique

[0002] With the negative impact of global warming and the formulation of my country's sustainable development strategy, environmental protection has been paid more and more attention in all walks of life. In the foundry industry, V-method molding is known as "green casting" because of its dry sand, no chemical pollution, and low energy consumption, and has been accepted by more and more companies. The current V-method molding mostly adopts the semi-automatic vibrating table shuttle movement and the fully automatic upper and lower box molding ring molding. The semi-automatic modeling is that two mobile vibrating tables shuttle back and forth. The model is fixed on the vibrating table and follows the movement of the vibrating table to complete film coating, spraying, drying, emptying the box, sanding, vibrating, and scraping ...
