Abstract

The invention relates to a shoulder injecting device for a hose upper part, comprising a controlling mechanism, a stand, an injection molding and discharging mechanism, a hose shoulder compression molding mechanism, a cooling molding mechanism, a turntable assembly and a driving part, wherein the injection molding and discharging mechanism, the hose shoulder compression molding mechanism, the cooling molding mechanism, the turntable assembly and the driving part are arranged on the stand, the turntable assembly comprises a turntable and a plurality of core rods, the core rods are arranged on the turntable and circularly arrayed relative to the center of the turntable, the driving part is connected with the turntable and used for driving the turntable to rotate, the injection molding and discharging mechanism, the hose shoulder compression molding mechanism and the cooling molding mechanism are arrayed to form a circle and respectively located above different core rods, the controlling mechanism is respectively and electrically connected with the injection molding and discharging mechanism, the hose shoulder compression molding mechanism, the cooling molding mechanism and the driving part, and preferably, the shoulder injecting device further comprises an automatic hose feeding mechanism and an automatic hose detaching mechanism. The invention further provides a related shoulder injecting method for the hose upper part. The shoulder injecting device for the hose upper part, provided by the invention, is skillful in design and concise in structure, has the advantages of high speed and high efficiency when used for shoulder injecting, and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of hoses, in particular to the technical field of hose manufacturing, in particular to a hose upper shoulder injection device and a related hose upper shoulder injection method. Background technique [0002] The commonly used way of injecting the upper part of the hose is to put the hose on the mandrel, press down the mold bowl platen, close the mold with the mandrel, and then the injection molding mechanism spits out the material, which is completed under the action of the molding mechanism and the cooling mechanism. Note the shoulder, which belongs to the mold bowl and the mandrel are first clamped, and then the material is discharged. This kind of shoulder injection method is not a wheel-disc rotary shoulder injection method. Usually, two sets of mandrels operate alternately and a set of molding mechanism cooperates to inject shoulders. Each set of mandrels is about 8 pieces, and the machine speed is abou...

Problems solved by technology

This kind of shoulder injection method is not a wheel-disc rotary shoulder injection method. Usually, two sets of mandrels operate alternately and a set of molding mechanism cooperates to inject shoulders. Each set of mandrels is about 8 pieces, and the machine speed is about 20 pieces / min. 3 to 4 operators are required, the speed is slow and the efficiency is low
