Dewaxing assembly line

Abstract

The invention provides a dewaxing assembly line, belongs to the technical field of foundry machinery, and solves the problems that impurities are mixed into wax recovered by the existing dewaxing assembly line formwork when the wax is molten, and grains of sand are attached inside the formwork. The dewaxing assembly line comprises a frame and a pool; a chain track is fixed on the frame and a hanging box moving along the chain track is arranged on the chain track; a cold water shower device and a hot water shower device are arranged on the frame; the cold water shower device is arranged at the outer side part of the pool; the hot water shower device is arranged above the inlet end of the pool; the cold water shower device, the hot water shower device and the pool are orderly arranged clockwise or anticlockwise; the hanging box can be driven to pass through the cold water shower device, the hot water shower device and the pool through the chain track; a plurality of heating sheets connected with a hot steam source are vertically arranged inside the pool, and the heating sheets partition the pool into a plurality of S-shaped channels connected in series. The dewaxing assembly line is simple in structure, good in wax melting effect, high in work efficiency and high in yield of the formwork.

Description

technical field [0001] The invention belongs to the technical field of foundry machinery, in particular to a lost wax assembly line. Background technique [0002] With the development of my country's industrial technology, investment casting is applied in different product production fields. Investment casting is also known as investment casting or lost wax casting. With the continuous development of investment casting production technology, investment casting equipment has also been developed and improved, and gradually adopted by professional precision casting factories. In investment casting, it is necessary to dissolve the wax patterns and wax sticks in the mold group that has made the mold shell, and the device that dissolves the wax mold and wax sticks in the mold set that has made the mold shell is called investment casting The assembly line used by the dewaxing device of the module is called the lost wax assembly line. The existing lost wax assembly line needs to ...

Problems solved by technology

The existing lost wax assembly line needs to recover the melted wax and reuse it when melting the wax. When making the mold, it directly enters the hot water pool through the hanging frame to melt the wax, and the mold shell is in the shell making process. The surface will be accompanied by dust, dust and many small sand particles. When the wax melts in the hot water pool, the small sand particles will also separate from the surface of the mold shell and sink into the hot water pool. The operator has to clean it frequently Hot water pool to avoid cloudy water quality in the hot pool, which increases the workload and reduces production efficiency. At the same time, dust and dust float on the water surface and mix with the wax, which causes the recovered wax to be mixed with impurities and difficult to be reused. question

At the same time, during the shell making process, there will be large grains of sand attached to the sprue of the mold shell. When it is in a hot water pool, as the wax at the sprue melts, the sand will fall into the mold shell and Attached to the inner wall of the mold shell, this will cause defects in the product formed when pouring after the investment mold is completed, and the product qualification rate is low
