Description

Technical Field

[0001] The utility model relates to the technical field of demoulding devices, in particular to a demoulding device. Background Art

[0002] When processing rubber, a shaping mold is needed. Since the rubber needs to be heated during the production process and then shaped in the mold, the rubber product needs to be taken out of the mold after it is formed. The common demolding method is to manually take it out of the mold. However, when the mold is opened, the surface temperature of the rubber product is high. If it is taken directly, it is easy to get burned. In addition, the mold is uneven, and the rubber product will stick to the mold. If the rubber product is pulled out of the mold when the temperature is high, it is easy to cause deformation or even damage to the rubber product. For this reason, we propose a demolding device to solve the above problems. Utility Model Content

[0031] The No. 1 lifting component 501 includes a No. 1 screw rod 5012 and a limit rod 5013 rotatably connected to the U-shaped mounting frame 1. The top of the U-shaped mounting frame 1 is fixedly connected to a No. 1 motor 5011. The No. 1 motor 5011 is a prior art and will not be described in detail herein. The top of the No. 1 screw rod 5012 passes through the U-shaped mounting frame 1 and is fixedly connected to the output end of the No. 1 motor 5011. A slider 5014 is provided on the No. 1 screw rod 5012 and the limit rod 5013, and the slider 5014 is threadedly connected and slidably connected to the No. 1 screw rod 5012 and the limit rod 5013 respectively, and the slider 5014 is fixedly connected to the side of the upper template 2.

[0032] The No. 2 lifting component 502 includes a No. 2 screw rod 5022 rotatably connected to the U-shaped mounting frame 1, and a No. 2 motor 5021 is fixedly connected to the top of the U-shaped mounting frame 1. The No. 2 motor 5021 is a prior art and will not be described in detail here. The top of the No. 2 screw rod 5022 passes through the U-shaped mounting frame 1 and is fixedly connected to the output end of the No. 2 motor 5021. The outer surface of the No. 2 screw rod 5022 is threadedly connected to a moving block 5023, one side of the moving block 5023 is in contact with one side of the rack 5032, and one end of the moving block 5023 is fixedly connected to a sleeve 5024, and the sleeve 5024 is sleeved on the outer surface of the fixed tube 403, and the sleeve 5024 corresponds to the lower template 3.

[0033] The rotating component 503 includes a gear 5031 fixedly connected to the outer surface of the fixed tube 403 , the gear 5031 corresponds to the lower template 3 , a rack 5032 is fixedly connected to the U-shaped mounting frame 1 , and the rack 5032 is meshed with the gear 5031 .

The impact plate 603 and the fixed plate 602 are fixedly connected via a plurality of springs 604.

[0035] After the rubber product is formed in the upper template 2 and the lower template 3, the coolant is injected into the inner cavity of the upper template 2 and the lower template 3 through the Y-tube 401. At this time, the coolant will cool the rubber product. Under the principle of thermal expansion and contraction, the rubber product will shrink, which is conducive to demolding. At the same time, the No. 1 motor 5011 is controlled to rotate with the No. 1 screw rod 5012 to move the slider 5014 upward. When the slider 5014 moves, it will move the upper template 2 upward, thereby separating the upper template 2 and the lower template 3 until the height of the upper template 2 exceeds the width of the lower template 2.

[0036] Then, the No. 2 motor is controlled to rotate the No. 2 screw rod 5022, and when the No. 2 screw rod 5022 rotates, it will move the shift block 5023 upward, and the movement of the shift block 503 will move the sleeve 5024 and the corresponding fixed tube 403 together, and then move the lower template 3 and the gear 5031 together, and when the gear 5031 moves, it will be relatively displaced with the rack 5032, so the gear 5031 will rotate, and when the gear 4031 rotates, it will rotate with the fixed tube 403 and the lower template 3 together, because the fixed tube 403 is rotatably connected to the connecting tube 402, the Y-shaped tube 401 will not hinder the rotation of the lower template 3.

[0037] Since the second screw rod 5022 and the rotating shaft 601 are connected by the transmission member 7, when the second screw rod 5022 rotates, it will rotate with the rotating shaft 601, and when the rotating shaft 601 rotates, it will rotate with the fixed plate 602, and the rotation of the fixed plate 602 will rotate with the impact plate 603, and the impact plate 603 will collide with the upper template 2 and the lower template 3 during the rotation process, so as to vibrate and make the rubber product stuck on the template fall off, which is beneficial to the demolding of the rubber, and after the impact plate 603 hits the upper template 2 and the lower template 3, it will move backward under the push of them and squeeze the spring 604 until the impact plate 603 is separated from them.
