Detailed Implementation
[0014] In the figure, the headstock 2 is fixed to the discharge end of the barrel 1 by the headstock fixing bolt 3, and the connecting block 4 is fixed to the headstock 2 by the connecting block fixing bolt 5, enhancing the stability of the structure. The locking device 6 is used to lock the relative position of the headstock 2 and the head 19 to prevent loosening during operation. The locking device 6 includes a rotatable locking handle, which can be rotated to lock or release the locking device 6. The headstock pin 7 passes through the pin holes on the headstock 2 and the connecting block 4 and is fixed by the headstock pin retaining ring 8, allowing the head 19 to swing around the headstock pin 7. The lead screw nut seat 9 is mounted on the locking device 6, and the lead screw nut 10 is installed inside the lead screw nut seat 9. The pressure block 11 is fixed to the locking device 6 by the pressure block fixing bolt 12 to press the lead screw nut seat 9, ensuring its stability. The lead screw 13 passes through the lead screw hole on the lead screw nut 10 and is interacted with by the operator via the handwheel 14. Rotating the handwheel 14 moves the lead screw 13 within the lead screw nut 10, thus enabling fine adjustment of the locking device 6. The support plate 15 is fixed to the locking device 6 by support plate fixing bolts 16 to prevent excessive opening and closing. The head pin 17 passes through the pin holes on the head 19 and head seat 2, and is fixed by the head pin retaining ring 18, further enhancing the stability of the head. The head 19 has a water chamber 22 inside, with an inlet 20 and an outlet 21 connected to it for water circulation and temperature control. The positioning pin 23 precisely positions the head 19 and the die 24 to ensure accurate alignment and assembly precision. The die 24 is fixed to the outlet of the head 19 by die fixing bolts 25 to form the final shape of the rubber compound. A head handle 26 is mounted on the head 19 for easy opening and closing by the operator.
