Description

Technical Field

[0001] This utility model relates to the field of rubber molding technology, and in particular to a novel hand-cranked demolding mechanism for a vacuum vulcanizing machine with a pneumatic sliding plate. Background Technology

[0002] With the development of the rubber industry, users have increasingly higher requirements for rubber molding equipment. More convenient operation and more user-friendly design are what more customers are pursuing.

[0003] Currently, in the rubber industry, vacuum vulcanizing molding machines undergo a vacuuming process during vulcanization to ensure that the produced products are free of air bubbles and have no defects in appearance. However, after vacuuming, the middle layer of the mold is often sucked up or stuck to the rubber material, making mold opening difficult and increasing the risk of mold damage. In the past, mold opening was done manually by workers using pry bars, which was time-consuming, labor-intensive, and greatly increased the operational risks for operators, while also accelerating the rate of mold damage.

[0004] With the development of the rubber industry, users have increasingly higher requirements for rubber molding equipment. More convenient operation and more user-friendly design are what more customers are pursuing.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] like Figures 1-14As shown, this utility model provides a novel hand-cranked demolding mechanism 100 for a vacuum vulcanizing machine with a pneumatic slide plate 3. It includes a cylinder assembly 1, a cylinder fixing plate 2, a slide plate 3, a slide plate guide rail 4, a lifting screw 5, and a lifting device 6. The cylinder assembly 1 is fixed to the slide plate guide rail 4, and the cylinder fixing plate 2 is located below the slide plate guide rail 4. The cylinder assembly 1 includes a cylinder 11 and a cylinder piston rod 12. The cylinder piston rod 12 is connected to one end of the slide plate 3, and the extension and retraction of the cylinder piston rod 12 drives the slide plate. 3. The slide plate 3 is mounted on the slide plate guide rail 4. At least four guide posts 7 are connected around the slide plate guide rail 4. The lower ends of the four guide posts 7 are connected to a guide post connecting plate 71. The lifting screw 5 passes through the guide post connecting plate 71 and the cylinder fixing plate 2 in sequence and is fixed to the cylinder fixing plate 2. The other end of the lifting screw 5 is connected to the lifting device 6. When the product vulcanization time is up, the vacuum hood rises. When the mold thickness is relatively thick, the lifting device 6 is shaken to drive the lifting screw 5 to rotate. Driven by the lifting screw 5, the guide post connecting plate 71 rises, causing the four guide posts 7 to rise simultaneously. The four guide posts 7 simultaneously drive the cylinder 11, the sliding plate guide rail 4, and the sliding plate 3 to rise. The four guide posts 7 ensure that the cylinder 11, the sliding plate guide rail 4, and the sliding plate 3 do not tilt during the ascent. The cylinder piston rod 12 extends, causing the sliding plate 3 to slide. After sliding, the sliding plate 3 locks the mold's lugs, causing the middle and lower plates of the mold to descend together with the main cylinder, thus opening the middle and lower molds. When the product's vulcanization time is up, the vacuum hood rises. When the mold thickness is relatively thin... The rocking lifting device 6 drives the lifting screw 5 to rotate, and the guide column connecting plate 71 descends under the drive of the lifting screw 5. The descent of the guide column connecting plate 71 drives the four guide columns 7 to descend simultaneously. The four guide columns 7 simultaneously drive the cylinder 11, the slide rail 4, and the slide plate 3 to descend. The four guide columns 7 support the cylinder 11, the slide rail 4, and the slide plate 3 to prevent tilting during the descent. The cylinder piston rod 12 extends and drives the slide plate 3 to slide. After the slide plate 3 slides, it locks the mold lugs, so that the middle plate and the lower plate of the mold descend together with the main cylinder, realizing the opening of the middle mold and the lower mold.

[0034] Preferably, the guide post connecting plate 71 is provided with a threaded hole that matches the lifting screw 5. When the lifting screw 5 rotates, the lifting screw 5 rotates relative to the threaded hole in the guide post connecting plate 71, causing the guide post connecting plate 71 to rise or fall. The guide post connecting plate 71 causes the four guide posts 7 to rise or fall simultaneously. The four guide posts 7 cause the slide rail 4, slide plate 3 and cylinder 11 to rise or fall synchronously, satisfying the mold opening of molds of different thicknesses.

[0035] Preferably, the cylinder assembly 1 further includes a cylinder bracket 13, the cylinder 11 is fixed on the cylinder bracket 13, and the cylinder bracket 13 supports the cylinder 11, resulting in a stable structure.

[0036] Preferably, a connecting bearing 21 is provided at the connection between the lifting screw 5 and the cylinder fixing plate 2, and a connecting bearing cover 22 is provided at the upper end of the connecting bearing 21.

When the lifting screw 5 rotates, the connecting bearing 21 reduces the friction between the lifting screw 5 and the cylinder fixing plate 2.

[0037] Preferably, a connecting block 8 is provided at the connection between the cylinder piston rod 12 and the slide plate 3. The cylinder piston rod 12 is connected to one end of the slide plate 3 through the connecting block 8. When the cylinder piston rod 12 extends or retracts, it causes the connecting block 8 to slide left or right. When the connecting block 8 slides left or right, it causes the slide plate 3 to slide left or right. When the cylinder piston rod 12 extends, the connecting block 8 causes the slide plate 3 to slide. After the slide plate 3 slides, it locks the lugs of the mold, so that the middle plate and the lower plate of the mold descend together with the main cylinder, thereby realizing the opening of the middle mold and the lower mold.

[0038] Preferably, the lifting device 6 includes a bevel gear 61, a drive shaft 62, a hand crank assembly 63, and a connecting plate 64. The bevel gear 61 is connected to one end of the lifting screw 5. The drive shaft 62 passes through the connecting plate 64, and one end of the connecting plate 64 is fixed to the cylinder fixing plate 2. The bevel gear 61 is a pair of bevel gears. In this embodiment, there are two bevel gears 61 that mesh with each other. The bevel gears 61 are installed at a 90° angle to the hand crank assembly 63, and the bevel gears 61 transmit power. The transmission shaft 62 is rotated at a 90° angle. One end of the transmission shaft 62 is connected to one side of the bevel gear 61, and the other end of the transmission shaft 62 is connected to the hand crank assembly 63. The connecting plate 64 is used to fix the transmission shaft 62. When the hand crank assembly 63 is rotated, the bevel gear 61 rotates synchronously, driving the lifting screw 5 to rotate. The guide post connecting plate 71 rises or falls through the threaded hole while the lifting screw 5 rotates. The guide post connecting plate 71 drives the four guide posts 7 to rise or fall. The four guide posts 7 drive the slide rail 4, the slide plate 3 and the cylinder 11 to rise or fall simultaneously.

[0039] Preferably, such as Figure 13 As shown, the hand-cranked assembly 63 includes a hand-cranked wheel 631 and a hand crank 632. One side of the hand-cranked wheel 631 is fixed to the transmission shaft 62, and the other side of the hand-cranked wheel 631 is fixed to the hand crank 632. Rotating the hand crank 632 drives the hand-cranked wheel 631 to rotate synchronously. The hand-cranked wheel 631 drives the transmission shaft 62 to rotate. The bevel gear 61 rotates under the drive of the transmission shaft 62. The rotation of the bevel gear 61 drives the lifting screw 5 to rotate. The guide post connecting plate 71 rises or falls through the threaded hole while the lifting screw 5 rotates. The guide post connecting plate 71 drives the four guide posts 7 to rise or fall. The four guide posts 7 drive the slide rail 4, the slide 3, and the cylinder 11 to rise or fall simultaneously.

[0040] Preferably, a limiting steel sleeve 65 is fitted onto the outer surface of the drive shaft 62, and a limiting bearing 66 is provided at the connection between the drive shaft 62 and the connecting plate 64, such as... Figure 12 As shown, the limiting steel sleeve 65 fixes the position of the transmission shaft 62 in place. When the transmission shaft 62 rotates, the limiting bearing 66 reduces the friction between the transmission shaft 62 and the connecting plate 64.

[0041] Preferably, such as Figure 9 As shown, an adjusting bolt 9 is provided between the connecting plate 64 and the slide rail 4. When the lifting screw 5 rotates, the adjusting bolt 9 supports the slide rail 4 without tilting, and the structure is stable.

[0042] Preferably, the cylinder assembly 1 is provided with at least two protrusions, and the slide rail 4 is provided with at least two grooves that match the two protrusions. The two protrusions are respectively inserted into the two grooves to fix the cylinder assembly 1 on the slide rail 4, and the cylinder assembly 1 is fixed on the slide rail 4 without tilting.

[0043] In summary, this utility model presents a novel hand-cranked demolding mechanism for a vacuum vulcanizing machine with pneumatic sliding plate assistance. A cylinder assembly is installed on the sliding plate guide rail, and a sliding plate is placed inside the guide rail. The piston rod of the cylinder assembly is connected to the sliding plate. Four guide pillars are connected to the lower end of the guide rail, and a guide pillar connecting plate is connected to the lower end of each guide pillar. One end of a lifting screw passes through the guide pillar connecting plate and connects to the cylinder fixing plate, while the other end is connected to a lifting device. The lifting device controls the rotation of the lifting screw. The rotation of the lifting screw causes the guide pillar connecting plate, guide pillars, sliding plate guide rail, sliding plate, and cylinder assembly to rise or fall. This mechanism is suitable for molds of different thicknesses. The extension and retraction of the cylinder piston rod controls the left and right movement of the sliding plate, and the extended sliding plate engages the mold to open it. Therefore, this novel hand-cranked demolding mechanism for a vacuum vulcanizing machine enables the opening of the middle and lower molds, offering convenient operation and minimal wear.
