In order to ensure the reliable transmission of the vibration motor, a vibration cylinder 502 is connected above the vibration motor, a rod of the vibration cylinder 502 extends out to press down the vibration motor, specifically, to press down a vibration transmission member 505 of the vibration motor, so as to prevent the vibration device 50 from separating from the mold 100 when vibrating, thereby ensuring the transmission of the vibration, and the vibration cylinder 502 may be an oil cylinder or an air cylinder. In addition, in order to prevent the vibration of the vibration motor from being directly and reversely transmitted to the vibration cylinder 502 to damage the vibration cylinder 502, the vibration cylinder 502 and the vibration motor may be connected through a buffering elastic member 503 to protect the vibration cylinder 502, and the buffering elastic member 503 may be a cushion pad or a cushion spring, and is specifically disposed between the rod of the vibration cylinder 502 and the vibration transmission member 505 of the vibration motor.

The middle part of the hook 402 is hinged to the base 401, the other end of the hook 402 is hinged to the cylinder rod of the driving cylinder 403, when the prefabricated part 200 needs to be hooked, the cylinder rod of the driving cylinder 403 extends out to drive the hook body to rotate to hook the prefabricated part 200, and when the cylinder rod retracts, the hook body can rotate reversely to be separated from the prefabricated part 200.

When the demoulding mechanism is provided with the lifting device and the vibrating device 50, the vibrating motor of the vibrating device 50 transmits vibration to the mould 100, so that the mould 100 and the prefabricated part 200 inside the mould are loosened to a certain extent, the lifting device lifts the prefabricated part 200 at the same time, namely, vibration and lifting are carried out synchronously, the power and the speed of lifting can be adjusted to be slow, the prefabricated part 200 and the mould 100 can be separated as soon as possible by slowly lifting while loosening, and therefore, the damage to the prefabricated part 200 and the mould 100 is reduced or avoided as far as possible, the aim of smooth demoulding is achieved, and the demoulding mechanism is different from the traditional 'violent' demoulding.

The above-mentioned lifting device and vibration device 50 are basic components for realizing smooth demolding, and for better demolding, the demolding mechanism provided in the present embodiment further includes a longitudinal beam 30, a transverse base frame, a longitudinal rail 10, and the like.

With continued reference to fig. 1-5, the stripper mechanism further includes a longitudinal beam 30, and the longitudinal beam 30 is provided with a plurality of the above-mentioned hook portions 40 and vibrating devices 50 along the longitudinal direction, as shown in fig. 5, four hook portions 40 and three vibrating devices 50 are arranged, and the hook portions 40 and the vibrating devices 50 are arranged in a staggered manner along the longitudinal beam 30.

Of course, the hook portion 40 and the vibration device 50 may be mounted on the same base, and specifically, the connection component of the vibration device 50, such as the sliding rod 504 and the hook portion 40, are mounted on the base to form the vibration demolding device. At this time, the vibration demoulding device is integrally installed on the longitudinal beam 30, at least two groups of vibration demoulding devices are installed along the direction of the longitudinal beam 30 so as to meet the distribution of a two-point hoisting method, and the hoisting driving part specifically hoists the longitudinal beam 30 to ascend and descend, so that the plurality of hoisting hook parts 40 and the vibration devices 50 on the longitudinal beam are driven to ascend and descend.

It should be noted that, the longitudinal direction and the transverse direction described herein may be referred to as a longitudinal direction in fig. 5, a left-right direction and a transverse direction perpendicular to the paper plane, or the mold 100 may be referred to as a transverse direction, and the longitudinal direction and the transverse direction of the mold 100 and the prefabricated part 200 formed therein are referred to as a longitudinal direction and a transverse direction. When the prefabricated member 200 has a long length, a plurality of (more than one) hook portions 40 and vibration devices 50 are provided, so that the hooking can be more stable and the vibration transmission can be more uniform, thereby ensuring that the entire prefabricated member 200 can be relatively smoothly separated from the mold 100, although the number of the hook portions 40 and the vibration devices 50 is not limited to that shown in fig. 4. In addition, a longitudinal beam 30 is arranged, the plurality of hook portions 40 and the vibration device 50 are arranged on the longitudinal beam 30, and the lifting driving portion lifts the longitudinal beam 30, so that the plurality of hook portions 40 and the vibration device 50 can be lifted, synchronous operation of the plurality of hook portions 40 and the vibration device 50 can be ensured, and stable demolding is facilitated. It is understood that, instead of providing the longitudinal beam 30, it is also possible to lift the plurality of hook portions 40 and the vibration devices 50 individually or to lift the combination of the plurality of hook portions 40 and the vibration devices 50 individually.

With continued reference to fig. 2 and 4, specifically, during lifting, the lifting driving portion includes a hoist 601, the demolding mechanism may include more than one hoist 601, and the longitudinal beam 30 is provided with a corresponding number or more of lifting pulley blocks 301, so that the lifting driving portion can stably lift the longitudinal beam 30, and two lifting pulley blocks 301 are shown in fig. 4. Fig. 4 shows that the wire rope 601a of the hoist 601 passes through the hoisting pulley block 301 of the longitudinal beam 30, when the hoist 601 lowers the wire rope 601a, the longitudinal beam 30 gradually descends, the vibration device 50 thereon falls on the top of the sidewall of the mold 100, and the hook part 40 of the hoisting device can hook the prefabricated part 200 in the mold 100 at this time, so that the synchronous operation of vibration and hoisting can be started.

It should be understood that the lifting force of the prefabricated part 200 can be the reaction force of the vibration cylinder 502 indirectly driving the mold 100, or the lifting force of the winch 601 driving the longitudinal beam 30 to drive the hook part 40 to lift the prefabricated part 200 upwards, and at the same time, the cylinder rod of the vibration cylinder 502 extends out to press the vibration transmission member 505 of the vibration motor downwards to continuously vibrate the mold. It can be seen that the hoisting driving part does not work during pre-demolding, and the small-amplitude hoisting which is performed synchronously with the vibration can be achieved based on the reaction force of the vibration device 50 when the hoisting hook part 40 hooks the prefabricated part 200, so that the pre-demolding effect is achieved.

It should be understood that, besides the hoisting 601, the hoisting driving part may also be a traveling crane, and the traveling crane is connected with the longitudinal beam 30 to drive the longitudinal beam 30 to ascend and descend.
