Embodiment 1

[0035] see Figure 1-9 , a circulating cooling tank for plastic pipe injection molding, including a cooling tank 10, a rotatable circulation shaft 13 is provided in the middle of the cooling tank 10, and multiple groups of fixed connections are provided on the circulation shaft 13 and are used for pipe body Fixed cooling frame 12, each group of cooling frames 12 is multiple, and cooling frame 12 is provided with a fixed groove 124 for tube body storage, the upper end of the fixed groove 124 is provided with openable and closed and used to prevent The sealing plate 121 that the pipe body drops.

[0036]The rotation of the circulating shaft 13 drives the cooling frame 12 to rotate periodically in the cooling tank 10, thereby realizing the rotation of the pipe body in the cooling tank 10, so that the pipe body can fully contact and cool with the cooling liquid at different positions in the cooling tank 10 , which improves the overall cooling efficiency; and the rotation of the c...

Abstract

The invention discloses a circulating cooling tank for plastic tube injection molding, which comprises a cooling tank, wherein the middle part of the cooling tank is provided with a rotatable circulating shaft, the circulating shaft is provided with a plurality of groups of cooling frames which are fixedly connected and are used for fixing tube bodies, each group comprises a plurality of cooling frames, and the cooling frames are internally provided with fixing grooves for storing the tube bodies; sealing plates which can be opened and closed and are used for preventing the tube bodies from falling off are arranged at the upper ends of the fixing grooves, and the cooling frames are driven to periodically rotate in the cooling tank through rotation of the circulating shaft, so that the tube bodies rotate in the cooling tank, the tube bodies can be fully in contact with cooling liquid at different positions in the cooling tank for cooling, and the overall cooling efficiency is improved; and the rotation of the circulating shaft also can realize a certain stirring effect, so that the cooling efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of plastic pipe production and processing, and in particular relates to a circulating cooling tank for injection molding of plastic pipes. Background technique [0002] Plastic pipes are generally made of synthetic resin, that is, polyester, added with stabilizers, lubricants, plasticizers, etc., and extruded in a pipe making machine by a "plastic" method. It is mainly used for water supply system piping, drainage, exhaust and sewage sanitary pipes, underground drainage pipe systems, rainwater pipes, and threading pipes for wire installation in housing construction. [0003] After the plastic pipe is injection molded, it is initially cooled, and then the pipe body is cut into the corresponding size, and then the cut pipe body is completely cooled. However, the existing cooling mechanism, when the pipe body is completely cooled, the cooling liquid The utilization rate is low and the cooling efficiency is low...
