Description
Technical Field
The invention relates to the technical field of casting devices, in particular to a device and a method capable of preventing resin sand from adhering to the inner wall of a sand hopper of a core making machine.
Background
The sand is mixed with two kinds of resin in a sand mixer, and then is sent to a mould of a core making machine for solidification, and the sand core is formed. And sand mixed with resin and discharged from the sand mixer is placed into a sand hopper of a conveying trolley, sent to a quicksand groove, then enters a sand hopper of a core making machine, and enters a sand shooting bin of the core making machine. In this process, any holding member with which the sand contacts will bond the resin sand at the contact surface, and as the daily production continues, the bonded sand slowly solidifies and accumulates more and more. Although the production is finished every day, the production is carefully cleaned, but the production is difficult to clean completely.
At present, manufacturers of existing core making machines face a problem that sand hoppers and raw material channels of the core making machines are frequently adhered and agglomerated due to the fact that sand and resin pass through every day, sand blasting cleaning cannot be thoroughly cleaned, and residual sand can affect the quality of finished products of next batch if not cleaned.

The technical scheme adopted by the invention for solving the technical problems is as follows: the device capable of avoiding resin sand from adhering to the inner wall of the core making machine sand hopper comprises the core making machine sand hopper, wherein a coating is coated on the inner side wall of the core making machine sand hopper, and the coating is a high-hardness Teflon coating.
A method capable of avoiding resin sand from adhering to the inner wall of a sand hopper of a core making machine comprises the following steps:
step 1) applying high-pressure alumina spray to the inner side wall of the core making machine sand hopper, so that the inner side wall of the core making machine sand hopper is cleaned and subjected to coarse manufacturing treatment;
step 2) spraying primer on the surface of the core making machine sand hopper after cleaning and rough machining;
and 3) after the primer is dried, spraying a high-hardness Teflon coating on the sand hopper of the core making machine, and heating and drying the surface of the sand hopper.
Specifically, the temperature of the heating and drying treatment of the core making machine sand hopper is 90-100 ℃.
Specifically, the high-hardness Teflon coating is suitable for the inner side wall of a sand hopper of a conveying trolley for conveying resin sand, the inner side wall of a sand flowing groove, the inner side wall of a sand shooting bin of a sand making machine and the inner side wall of a conveying pipeline.
The invention has the beneficial effects that:
according to the device and the method for preventing the resin sand from adhering to the inner wall of the core making machine sand hopper, disclosed by the invention, the adhesive force between the resin sand and the inner side walls of the core making machine sand hopper and the conveying pipeline can be reduced by spraying the high-hardness Teflon coating on the inner side wall of the core making machine sand hopper and the inner side wall of the conveying pipeline, so that the resin sand is not easily adhered to the inner side wall of the core making machine sand hopper and the inner side wall of the conveying pipeline, the cleaning of the inner side wall of the core making machine sand hopper and the inner side wall of the conveying pipeline is convenient, the difficulty of manual cleaning is greatly reduced, the production efficiency is effectively increased, and the quality of a next-batch finished product is improved.
