Tin ring casting method and device

Abstract

The invention provides a tin ring casting method and device. The tin ring casting method includes the following steps of S1, putting a tin material into a feeding cylinder, and heating the feeding cylinder so that the tin material can be hot-molten into molten tin and the molten tin can flow into a closed discharge port to stand for use; S2, ejecting an ejector pin in a die to exhaust the air in aproduct molding groove, and making a notch of the product molding groove seamlessly attached to and in butt joint with the discharge port; S3, pressurizing the feeding cylinder, opening the dischargeport, making the ejector pin retreat to empty the product molding groove, and injecting the molten tin into the product molding groove, wherein the molten tin injection time is controlled to be 0-1 s; S4, disengaging the discharge port out of the die so that the molten tin can be cooled and molded; and S5, automatically ejecting out the cooled and molded tin ring, and pushing away the die for collection treatment. The tin ring casting device comprises a feeding mechanism, a molding and moving module, a molding structure, an ejecting-out mechanism and a pushing mechanism. The tin ring castingmethod and device have the advantages that the product specification and quality are unified, material waste is reduced, and time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of tin ring processing and molding, in particular to a tin ring casting method and equipment. Background technique [0002] Tin ring is one of the commonly used materials in soldering. In the soldering process, the tin ring is placed on the device that needs to be soldered, and then the tin ring is heated and melted on the workpiece to achieve soldering, which can effectively improve work efficiency. . At present, the production and processing method of tin rings is mainly centrifugal casting. In the process of centrifugal casting tin rings, since the mold is made of silica gel material, the silicone material mold will expand with heat and contract with cold during the heating process, making the molded There are problems such as different specifications and shapes of tin rings, so when the tin rings are cast and demolded, they must be pulled out manually, and in the production process, due to the use of ce...
