Option 2 and option 1 are basically the same but in different ways.
The open mode sequence control mechanism is shown in Figure 1.
The application example is shown in Figure 2.
The principle of open mode action is shown in Figure 3.
More details are displayed below, you can have a view of all drawings.
In figure 1:
Number 1 stands for fixing pedestal.
Number 2 stands for lever pin.
Number 3 stands for drawhook.
Number 4 stands for Pull block.
Capital letter S stands for mold opening stroke.
In figure 3:
Letter a means the location of each part under closing status.
Notice: The active pin must be locked to prevent the hook from falling off.
Letter b means that the pull block moves to a preset distance position, giving space for the active pin to exit.
Letter c means to continue to open the mold, pull the hook slope squeeze the active pin, make it out of the pull hook, complete the process of opening the mold.
Design specifications:
1. When we opening the mold, the pull block is prohibited from completely out of the fixed seat, can only stay in the preset position, so the mold must do a good job of limiting.
2. In this way, the template in which the pull block is located can only start to fit after the hook is inserted into the fixed seat and the top surface exceeds the active pin, otherwise, it will become stuck and affect the die action.
3. Other considerations are the same as option 1.
