A water delivery mechanism of a turntable device

Abstract

The invention discloses a water conveying mechanism of a turntable device. The water conveying mechanism of the turntable device comprises a mandrel, a water conveying sleeve, two first water sealing sleeves, two second water sealing sleeves and elastic devices, wherein a water conveying pipeline is arranged in the mandrel; a first transfer port is formed in the outer peripheral wall; the water conveying sleeve rotationally sleeves the mandrel; a second transfer port is formed in the inner peripheral wall; a connecting port is formed in the outer wall; the first transfer port and / or the second transfer port are annularly encircled out of the mandrel; the two first water sealing sleeves are arranged at the upper end and the lower end of the water conveying sleeve, and sleeve the mandrel; first sealing rings are cushioned between the first water sealing sleeves and the water conveying sleeve; the two second water sealing sleeves sleeve the mandrel in an up-down sliding mode, and are positioned at the ends, far from the water conveying sleeve, of the two first water sealing sleeves; second sealing rings are cushioned between the second water sealing sleeves and the mandrel; and the elastic devices are used for tightly pressing the second water sealing sleeves on the adjacent first water sealing sleeves. The water conveying mechanism of the turntable device can effectively reduce the magnitude of resistance suffered by the water conveying sleeve during rotating, prolongs the service life, and is convenient to machine, mount and use.

Description

technical field [0001] The invention relates to a turntable device, in particular to a water delivery mechanism of the turntable device. Background technique [0002] The turntable device carries out circular circular transportation through the disc body, which can effectively reduce the volume of the equipment, and is widely used in various processing equipment, including injection molding devices, casting devices, hot-melt molding devices, hot-melt bonding devices, etc. In the equipment that uses high temperature for processing operations, water cooling devices are often equipped to cool the molds and fixtures on the disc body to improve production efficiency. However, when the turntable device is working, the disc body needs to rotate around the central spindle. To prevent the water delivery pipe from being coiled on the main shaft of the turntable device, it is necessary to use corresponding water delivery mechanisms for water delivery. These water delivery mechanisms ma...

Problems solved by technology

[0003] Sealing is required between the mandrel and the water-carrying jacket to prevent water from leaking out. In the water-carrying mechanism of the existing turntable device, a rubber pad is usually used between the outer peripheral wall of the mandrel and the inner peripheral wall of the water-carrying jacket. For sealing, the machining accuracy of the mandrel and the water-carrying sleeve is high, and it is inconvenient to replace and replace. Moreover, the contact surface between the rubber pad and the mandrel and the water-carrying jacket is relatively large, which may easily cause excessive friction and affect the disc body. The normal rotation, the rubber pad is also easy to wear, and the service life is short
