Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings.

As shown in fig. 1, 2, 3, the utility model discloses a threading well mould, including bed die 1 and formpiston 2, formpiston 2 and bed die 1 and between form die cavity 3, all be equipped with electrical heating rod 4 in the wall of bed die 1 and formpiston 2, electrical heating rod 4 in bed die 1 is parallel with the horizontal plane, electrical heating rod 4 in bed die 1 vertically with transversely crisscross the setting, electrical heating rod 4's both ends stretch out bed die 1. An electric heating rod 4 parallel to a horizontal plane and an electric heating rod 4 parallel to a vertical plane are arranged in the male die 2, and two ends of the electric heating rod 4 extend out of the female die 1. The electric heating rod 4 can heat and solidify the well lid material.

The left side and the right side of the female die 1 are respectively provided with a round hole 12, and the round holes 12 are communicated with the die cavity 3; the left side and the right side of the female die 1 are provided with a driving device 6, and the driving device 6 selects an oil cylinder. The output end of the driving device 6 is connected with a push rod 5 matched with the round hole 12, and the push rod 5 can operatively penetrate through the round hole 12 to extend into the cavity 3 to be propped against the male die 2.
