[0040] Specifically refer to Figure 1 And Figure 2 In the embodiment, the second end of first locking arm 1 is provided with limiting piece 11 between second locking arm 2, to limit the amplitude of the second end of second locking arm 2 relative to first locking arm 1 swing downward when telescopic drive 3 is in the jacking state;

[0041] The second end of second locking arm 2 is provided with first locking portion 21, and the first locking hook 42 is arranged on the end mold main body 4, so that first locking portion 21 is clamped into or separated from first locking hook 42 when telescopic drive 3 drives first locking arm 1 and second locking arm 2 swing. Telescopic drive 3 can be cylinder, oil cylinder or electric push rod, etc.

[0042] The end mold locking device of the embodiment, when telescopic drive 3 telescopes, can drive first locking arm 1 and second locking arm 2 swing, limit the amplitude of the second end of second locking arm 2 relative to first locking arm 1 swing downward through limiting piece 11, so that first locking portion 21 on second locking arm 2 can be extremely conveniently clamped into first locking hook 42 (as shown in Figure 2 Or separated from first locking hook 42 (as shown in Figure 1The first locking arm 1 and the second locking arm 2 are hingedly connected, so that the second locking arm 2 can rotate relative to the first locking arm 1. After the first locking portion 21 is clamped into the first locking hook 42, the second locking arm 2 continues to swing and can pull the end mold body 4 to the end mold support 41, until the end mold body 4 is tightly abutted against the end mold support 41, so as to realize complete locking of the end mold 4 and the end mold support 41. Compared with the existing technology of locking by cooperation of the ejector rod and the hole, the end mold locking device of the embodiment has lower requirements for processing and operation of the end mold and itself.

[0043] Specifically referring to Figure 4 and Figure 6 In the embodiment, the first locking arm 1 includes two first locking plates 12 arranged in parallel and a first reinforcing plate 13 connected between the two first locking plates 12, so that the first locking arm 1 has high structural strength, and the frame structure can reduce the self weight. The second locking arm 2 includes two second locking plates 22 arranged in parallel and a second reinforcing plate 23 connected between the two second locking plates 22, so that the second locking arm 2 has high structural strength, and the frame structure can reduce the self weight. The first locking portion 21 is a first locking shaft. The first locking portion 21 adopts a locking shaft, which is convenient for cooperation with the first locking hook 42, realizes smooth clamping and disengagement, and can be reliably locked after clamping.
