[0050] Reference Figure 3 and Figure 4 A mounting groove 331 is provided in the limit block 33 near the height limit rod 31, and a limiting plate 34 is fixedly installed on the bottom wall of the shift rod 32.

[0053] Reference Figure 1 and Figure 3 When the mold is controlled to rise, the second lifting rod 222 drives the guide rod 225 to move toward the limit block 33, so that the guide rod 225 hits the guide slope on the gear lever 32 and slides along the guide slope, thereby controlling the gear lever 32 to move downward and compress the limit spring 35. Driven by the second lifting rod 222, the guide rod 225 continues to move to pass over the end of the gear lever 32 and moves to hit the height limiting rod 31. At this time, the gear lever 32 moves upward and resets under the action of the limit spring 35, so that the guide rod 225 falls between the gear lever 32 and the height limiting rod 31, thereby realizing the positioning of the second lifting rod 222, thereby realizing the limitation of the height of the mold rise.

[0054] Reference Figure 1 and Figure 3 When it is necessary to control the replacement table 21 to descend, the unlocking rod 36 is pressed into the limit block 33, thereby compressing the unlocking spring 38, so that the abutting inclined surface of the unlocking plate 37 abuts against the side wall of the limit plate 34, and drives the limit plate 34 to move downward, thereby compressing the limit spring 35, so that the gear rod 32 descends to a position lower than the guide rod 225, so as to facilitate the control of the guide rod 225 to move out from between the gear rod 32 and the height limiting rod 31, thereby facilitating the replacement table 21 to descend.

[0055] Reference Figure 5The height limiting mechanism 3 also includes a positioning component 39 for positioning the limit block 33. The positioning component 39 includes a positioning rod 391 and a positioning spring 392. A limit hole 332 is provided on the side wall of the limit block 33. The positioning rod 391 is slidably installed in the limit hole 332, and both ends of the positioning rod 391 extend out of the limit hole 332. The positioning spring 392 is installed in the limit hole 332, and one end of the positioning spring 392 is in conflict with the inner top wall of the limit hole 332, and the other end is fixedly installed with a positioning ring 393. The side wall of the positioning ring 393 away from the positioning spring 392 is in conflict with the side wall of the positioning rod 391.

[0056] Reference Figure 5 and Figure 6 An unlocking hole 2261 is provided on the side wall of the mounting frame 226 along the length direction of the mounting frame 226, and a plurality of positioning grooves 2262 are provided on the side wall of the mounting frame 226 at the bottom wall of the unlocking hole 2261. The plurality of positioning grooves 2262 are arranged along the length direction of the mounting frame 226, and the positioning grooves 2262 are used for the positioning rod 391 to be inserted. One end of the unlocking rod 36 located outside the limiting block 33 passes through the unlocking hole 2261, and the unlocking spring 38 also passes through the unlocking hole 2261.

[0057] Reference Figure 1 and Figure 6 When the height of the mold rise needs to be adjusted, the positioning rod 391 is pushed upward so that the positioning rod 391 moves from the positioning slot 2262 to the unlocking hole 2261. At this time, the height is adjusted as needed. If the height of the mold rise needs to be increased, the limit block 33 is slid toward the first lifting rod 221. If the height of the mold rise needs to be lowered, the limit block 33 is slid away from the first lifting rod 221, and then the positioning rod 391 is released, so that the positioning rod 391 moves downward and resets under the action of the positioning spring 392, so that the positioning rod 391 falls into the new positioning slot 2262, thereby adjusting the position of the limit block 33.

[0058] Reference Figure 1 A sliding component 4 is installed on the replacement table 21, and the sliding component 4 includes a sliding ball and a sliding seat 41. A plurality of sliding seats 41 are provided, and the plurality of sliding seats 41 are fixedly installed on the top wall of the replacement table 21, and the plurality of sliding seats 41 are distributed on the top wall of the replacement table 21, and the sliding ball is embedded in the sliding seat 41.

[0059] The working principle of the embodiment of the present application is as follows: the mold is placed on the replacement table 21 so that the sliding ball supports the mold, and then the position of the limit block 33 on the mounting frame 226 is adjusted according to the height of the molding machine, and the positioning rod 391 is inserted into the positioning groove 2262, thereby limiting the limit block 33. Then, the lifting handle 224 is controlled to rotate forward, thereby driving the lifting screw rod 223 to rotate, thereby driving the guide rod 225 to move in the direction of the limit block 33, thereby driving the replacement table 21 to rise through the first lifting rod 221 and the second lifting rod 222. When the guide rod 225 moves to contact the gear rod 32, the guide rod 225 presses the gear rod 32 downward, so that the limit plate 34 on the gear rod 32 presses the limit spring 35. When the guide rod 225 moves to contact the height limit rod 31, the gear rod 32 moves upward and resets under the action of the limit spring 35, so that the guide rod 225 falls between the gear rod 32 and the height limit rod 31, thereby limiting the guide rod 225 and making the replacement table 21 rise to a suitable height. Then push the mold into the molding machine, so as to realize the delivery of the mold into the molding machine.

[0060] Then, the unlocking rod 36 is pressed down, so that the unlocking plate 37 on the unlocking rod 36 contacts the limit plate 34, and the limit plate 34 is pressed downward, so that the limit plate 34 drives the gear rod 32 to move downward to a height lower than the guide rod 225. At this time, the lifting handle 224 is controlled to rotate in the opposite direction, thereby driving the screw rod to rotate, so that the guide rod 225 is moved out from between the gear rod 32 and the height limiting rod 31, thereby driving the replacement table 21 to descend to the initial height through the first lifting rod 221 and the second lifting rod 222 to facilitate the placement of a new mold.

[0065] The working principle of the embodiment of the present application is as follows: the position of the limit block 33 on the mounting frame 226 is adjusted according to the height of the bearing platform 7. After the adjustment is completed, the limit block 33 is positioned by the positioning rod 391. Then, a new mold is placed on the replacement platform 21 in the chassis 5. Then, the lifting mechanism 22 is controlled to move, thereby driving the replacement platform 21 to rise to the guide plate 10, so that the bottom wall of the guide plate 10 contacts the top wall of the replacement platform 21. At this time, the guide rod 225 moves between the gear rod 32 and the height limit rod 31, and then the mold is rotated on the replacement platform 21 at a certain angle, so that the mold is at an angle suitable for installation on the bearing platform 7, and then the mold is pushed from the replacement platform 21 to the bearing platform 7. Finally, by contacting one end of the locking rod 93 with the edge of the mold, the second locking tooth 95 at the other end of the locking rod 93 is meshed with the first locking tooth 92 of the positioning wedge block 91, and then the locking rod 93 is positioned on the bearing platform 7 by the positioning bolt 96, so as to position the mold.
