[0052] About the working situation of the mold changing car:

[0053] When the equipment is changing molds, the two conical guide pins 39 at the bottom of the mold changing cart cooperate with the guide pin holes in the equipment to complete the guidance. Figure 3 , 4, after the mold-changing vehicle is close to the equipment (the front end of the telescopic latch 72 is conical and the rear end is flat; there is a set of springs 73 between the flat end and the baffle at the rear end; the front end of the telescopic latch 72 is normally extended out of the mounting seat 66; the spring 73 is not compressed when the mold-changing vehicle is not close to the locking block 71, and the cam 65 is not aligned with the notch of the telescopic latch 72, and the operating rod 64 cannot be rotated; when the mold-changing vehicle is close to the locking block 71, the front end of the telescopic latch 72 contacts the locking block 71, the spring 73 is compressed, and the notch of the telescopic latch 72 is aligned with the cam 65, and the operating rod 64 can be rotated), the operating rod 64 is manually rotated 90° (the cam 65 installed at the front section of the operating rod 64 and the locking plate 67 of the oblong plate structure are relatively fixed with the operating rod 64). When the operating rod 64 rotates, it drives the locking plate 67 and the gear lever 68 to change from a vertical state to a horizontal state, so that the locking plate 67 is stuck in the locking block 71. At the same time, a proximity switch is installed below the lock groove in the locking block 71. When the locking plate 67 is in a horizontal position, the proximity switch will detect the locking plate 67. After the PLC detects the locking plate 67, it is determined that the mold change vehicle is ready, and the mold change program can be executed at this time.

[0054] The mold changing procedure is started manually. When the equipment executes the mold changing procedure, the positioning pin cylinder under the workbench is first retracted, and then the (lower mold) fixed presses on both sides of the workbench are released, and then the (mold changing) lifting mechanism lifts the entire pressing tool to make the height of the pressing tool consistent with the height of the mold changing cart. After lifting, the pressing tool is pushed into the mold changing cart manually. After the pressing tool is in place in the mold changing cart, the safety pin 43 is first inserted (the first step of safety measures). When the mold changing cart is separated from the equipment, the joystick 64 needs to be turned (while turning the joystick 64, the gear lever 68 and the locking plate 67 are both turned from the horizontal state to the vertical state. At this time, the mold changing cart and the equipment are unlocked, and the gear lever 68 plays the role of the second step of safety measures).
