DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model embodiment discloses a plastic hose injection molding device.

[0026] Before molding the plastic hose, determine the wall thickness of the hose to be molded, and support the support column 5 so that the injection ring 6 can drive multiple molding mold sleeves 8 to rotate, and rotate the molding mold sleeves 8 of corresponding specifications to the top of the molding core 10, and then start the first electric cylinder 2, so that the top plate 3 can drive the vertical plate 4 and the molding mold sleeve 8 to move down and be sleeved on the outside of the molding core 10, and then pass the hot melt material through the two first injection ports 7 and the second injection ports 11 connected above the molding mold sleeve 8 to between the molding mold sleeve 8 and the molding core 10, so that the hose can be cooled and molded on the outside of the molding core 10, and then the first electric cylinder 2 can be started again, so that the vertical plate 4 drives the molding mold sleeve 8 away from the molding core 10, so that the molded hose can be pulled out from the molding core 10.

[0027] In order to be able to stably rotate the forming mold sleeve 8 and arrange it above the forming mold core 10 according to the wall thickness of the hose to be prepared, as shown in FIG. Figure 2-3 As shown, a second electric cylinder 12 is fixedly provided at the upper end of the back side of the top plate 3, a connecting ring 13 is fixedly provided at the end of the second electric cylinder 12, a plurality of support rods 14 arranged at intervals are fixedly provided on the side wall of the connecting ring 13, a push plate 15 is rotatably sleeved on the rod wall of the support rod 14, a limiting rod 16 is contacted at the bottom of the push plate 15, the limiting rod 16 is fixedly connected to the inner wall of the connecting ring 13, a torsion spring 17 is sleeved on the rod wall of the support rod 14, and the two ends of the torsion spring 17 are respectively fixedly connected to the push plate 15 and the support rod 14, a ratchet 18 is fixedly sleeved on the back side of the support column 5, and a plurality of push plates 15 are matched with the ratchet 18;

[0028] An auxiliary limit block 21 is fixedly provided on the outer wall of the piston rod of the first electric cylinder 2 through a telescopic rod 20. The auxiliary limit block 21 is arranged in an inclined surface on the side close to the forming mold sleeve 8. A spring 22 is fixedly provided between the telescopic rod 20 and the auxiliary limit block 21. The spring 22 is sleeved on the outer side of the sleeve rod end of the telescopic rod 20.

[0029] When it is necessary to select the molding die sleeve 8, the second electric cylinder 12 is started, so that the connecting ring 13 can be pulled. At this time, multiple push plates 15 begin to cooperate with the extrusion of the ratchet 18 under the support of the limit rod 16 to push the ratchet 18, so that the ratchet 18 drives the support column 5 and the injection ring 6 to rotate, so that multiple molding die sleeves 8 can rotate and complete the position change. When the position adjustment of the molding die sleeve 8 is completed, the second electric cylinder 12 pushes back. At this time, under the elastic force of the torsion spring 17, the push plate 15 only contacts with the ratchet teeth 18 without generating thrust, so that the position of the extrusion 18 is not affected, and the position of the molding die sleeve 8 is not affected. At the same time, when the molding die sleeve 8 rotates, the molding die sleeve 8 can be auxiliary supported by the elastic support of the auxiliary limit block 21 and the spring 22, so as to avoid the position of the molding die sleeve 8 from being adjusted as much as possible, and ensure the stability of the hose molding process.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
