[0002] There are various production equipments for soles. Among them, the sole injection molding machine injects the material into the mold under high pressure through injection molding. During the injection molding, the sole injection molding machine will use the hydraulic control device to start the hydraulic device to squeeze and fix the mold, so that the sole injection molding machine will injection mold the sole in the mold.

[0003] However, the hydraulic push rod of the hydraulic control device of the existing sole injection molding machine is of fixed size, and the contact area between the hydraulic push rod and the mold is limited. When the hydraulic push rod pushes and extrude a larger mold, the mold is subjected to uneven force, and the injection-molded sole is prone to overflow from the mold, which is not conducive to subsequent production and processing. The hydraulic push rod is prone to deviation when used for a long time under high pressure, which affects its service life. In order to solve the shortcomings of the existing technology, we propose a hydraulic control device for a sole injection molding machine. Utility Model Content

A rotating shaft 12 is rotatably connected inside the installation groove 11. A screw rod 13 is detachably installed at one end of the rotating shaft 12, and a rotating head 15 is detachably installed at the other end of the rotating shaft 12. Second extension holes 14 are provided on both symmetrical sides of the installation sleeve 7, and a cross groove is provided at one end of the rotating head 15. The inner wall of the second extension hole 14 is provided with a thread, and the inside of the second extension hole 14 is threadedly connected to the outer side of the screw rod 13. A first limiting ring 20 is detachably sleeved on the outer side of one end of the extension rod 9, and a second limiting ring 21 is detachably installed on the inner wall of the first extension hole 8, so that the second limiting ring 21 limits the first limiting ring 20 to prevent the extension rod 9 connected to the first limiting ring 20 from slipping out.

[0023] To adjust the extension component 5, the staff uses the cross groove provided on the rotating head 15 to rotate the rotating head 15 to drive the rotating shaft 12 to drive the screw rod 13 to rotate in the second extension hole 14. The screw rod 13 is screwed out in the second extension hole 14 through the thread to push the rotating shaft 12 to push the extension arc plate 10 to drive the extension rod 9 to drive the first limit ring 20 to slide out in the first extension hole 8, thereby adjusting the position of the extension arc plate 10 together with the screw rod 13 on the mounting sleeve 7.

[0025] How it works

[0026] It should be noted that the utility model is a hydraulic control device for a sole injection molding machine. When in use, the staff first rotates the rotating head 15 using the cross groove provided on the rotating head 15. The rotating head 15 rotates to drive the rotating shaft 12 to drive the screw rod 13 to rotate in the second extension hole 14. The screw rod 13 is screwed out of the second extension hole 14 through the thread. The screw rod 13 pushes the rotating shaft 12 to push the extended arc plate 10 to drive the extension rod 9 to drive the first limit ring 20 to slide out of the first extension hole 8. The length of the screw rod 13 rotating out of the second extension hole 14 is adjusted according to the mold size. The screw rod 13 is adjusted to be close to the mold length within the adjustment range of the screw rod 13, and the hydraulic press 2 is started. The push rod of the hydraulic press 2 pushes the installation sleeve 7 to drive the screw rod 13 and the extension rod 9. The screw rod 13 and the extension rod 9 drive the extended arc plate 10, so that the push rod installation sleeve 7 of the hydraulic press 2 cooperates with the top of the extended arc plate 10 to push the bottom of the mold, thereby achieving the purpose of increasing the contact area between the push rod of the hydraulic press 2 and the mold.

[0027] When the push rod of the hydraulic press 2 is pushed toward the bottom of the mold, the push rod of the hydraulic press 2 drives the ball 19 to roll in the limit groove opened in the fixed ring 18 under the action of friction during the movement. When the ball 19 rolls in the limit groove opened in the fixed ring 18, the fixed ring 18 is supported by the connecting plate 17, the connecting plate 17 is supported by the fixed collar 16, and the fixed collar 16 is supported by the fixed rod 3.
