The outer die 5 is provided with an overflow hole 14, and the overflow hole 14 is arranged at the upper end of the outer die 5. The outer ring 4 and the bottom barrel 2 have the same height. The external mold 5 and the internal mold 6 have the same height. The longitudinal section of the adjusting nut 11 is I-shaped, and the fixing frame 8 is inserted on the I-shaped grooves on the two sides in a sliding manner.

The following is a description of the materials and shapes of the devices in this case:

outer mold: steel tubular structure

Internal mold: steel tubular structure

All the electric parts in the scheme are connected with the adaptive power supply through the conducting wires, and an appropriate controller is selected according to actual conditions to meet control requirements, specific connection and control sequences.

In this embodiment:

the device is of a purely mechanical construction and therefore does not require a controller or electrical components.

Firstly, the device is assembled, a cover plate 12 is placed on the upper ends of an outer die 5 and an inner die 6, then a fixing screw 10 on a fixing frame 8 is screwed and installed on a fixing nut 9 on the upper ends of the outer die 5 and the inner die 6, then a gap formed by the outer die 5 and the inner die 6 which are formed into a whole in the process is sleeved on a bottom barrel 2, and then the formed whole is placed in an epoxy resin pouring machine.
