Description

Technical Field

[0001] This utility model relates to the field of hot press technology, and in particular to a lifting structure for the front door of a hot press. Background Technology

[0002] A hot press is a type of equipment widely used in industrial production. Its main function is to shape or solidify materials under heating and pressure. The front and rear doors of the hot press need to be moved up and down by a lifting structure so that the hot press is in the open and closed state.

[0003] The existing technology has the following problems:

[0004] The existing hot press has a track above and below the front door. The front door is embedded in the track and slides left and right using a hydraulic rod to open and close. Therefore, space needs to be left on the right side of the hot press to facilitate the placement of the front door track. Initially, the front door is in the track on the right side. When closing is required, a hydraulic push rod pulls the front door to the closed position. This structure is complex, requires sufficient space on one side of the hot press, wastes space, increases the travel distance of the trolley, and is inefficient. Utility Model Content

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1-Figure 5 As shown, a front door lifting structure for a hot press includes a hot press body 1. Mounting plates 2 are fixedly connected to the left and right sides of the hot press body 1. Rotating frames 3 are fixedly connected to the two mounting plates 2 on the side away from the hot press body 1 near the upper front side. Mechanism plates 4 are fixedly connected to the lower middle part of the front side and the upper part near the front side of the hot press body 1. A front door mechanism 5 is fixedly connected to the upper part of the hot press body 1 near the front side.

[0026] The front door mechanism 5 includes a motor 51. The lower side of the motor 51 is fixedly connected to the upper side of the hot press body 1 near the front side. The output end of the motor 51 is fixedly connected to a reducer 52. The output end of the reducer 52 is fixedly connected to a transmission rod 53. Two symmetrically distributed storage wheels 54 are fixedly connected to the outer side of the transmission rod 53. A traction belt 55 is wound around the inner side of each of the two storage wheels 54. The lower end of the traction belt 55 is fixedly connected to the front door body 56.

[0027] like Figure 3 As shown, the outer side of the transmission rod 53 is rotatably connected to the inner side of the rotating frame 3 near the left and right ends, which serves to support the transmission rod 53. The motor 51 drives the transmission rod 53 to rotate. When the transmission rod 53 rotates, it drives the storage wheel 54 to rotate. When the storage wheel 54 rotates, the traction belt 55 extends or retracts from the inner side of the storage wheel 54, thereby achieving the purpose of moving the front door body 56 up and down.

[0028] like Figure 3 As shown, guide rails 57 are slidably connected to the left and right sides of the front door body 56. A connecting rod 58 is rotatably connected to the side of the two guide rails 57 away from the front door body 56. The rear end of the connecting rod 58 is movably installed on the side of the mounting plate 2 away from the hot press body 1 and close to the front side.

[0029] like Figure 2 , Figure 3 As shown, a power component is provided between the connecting rod 58 and the mounting plate 2, which can drive the connecting rod 58 to rotate. When the connecting rod 58 rotates, the guide rail 57 moves back and forth, causing the guide rail 57 to drive the front door body 56 to move back and forth, thereby playing the role of opening and closing the front door body 56.

[0030] like Figure 1 , Figure 4 As shown, two fixed components 59 are fixedly connected to the front side of the front door body 56, which are distributed vertically. The fixed components 59 include a first crossbar 592. The rear side of the first crossbar 592 is slidably connected to the front side of the front door body 56. Several horizontally distributed first electromagnetic push rods 591 are fixedly connected to the side of the first crossbar 592 away from the mechanism plate 4. The side of the first electromagnetic push rods 591 away from the mechanism plate 4 is fixedly connected to the boss on the front side of the front door body 56. Several horizontally distributed limiting rods 593 are movably sleeved on the inner side of the first crossbar 592. A second crossbar 594 is fixedly connected to the side of the limiting rods 593 near the mechanism plate 4. Several horizontally distributed insert plates 595 are fixedly connected to the side of the second crossbar 594 near the mechanism plate 4. A fixing plate 510 is movably sleeved on the outer side of the insert plate 595. The rear side of the fixing plate 510 is movably installed on the front side of the mechanism plate 4.

[0031] It should be noted that the first electromagnetic push rod 591 drives the first crossbar 592 to move up and down. When the first crossbar 592 moves up and down, it relies on the limiting rod 593 to drive the second crossbar 594 to move up and down, thereby causing the insert plate 595 to move up and down. When the insert plate 595 is inserted into the inner side of the fixing plate 510, the fixing plate 510 fixes the front door body 56. The lower fixing plate 510 and the lower mechanism plate 4 are slidably connected in the vertical direction, and the upper fixing plate 510 and the upper mechanism plate 4 are fixedly connected.

[0032] like Figure 4 As shown, a first spring 596 is movably sleeved on the outer side of several limiting rods 593, and the first spring 596 is located on the side of the first crossbar 592 away from the first electromagnetic push rod 591.

[0033] It should be noted that the first spring 596 pushes the second crossbar 594, causing the contact between the insert plate 595 and the fixed plate 510 to be non-rigid, thus avoiding excessive extension of the length of the first electromagnetic push rod 591 and damage to the components.

[0034] like Figure 5 As shown, the insert plate 595 is in the shape of a right trapezoid, and the inclined surface of the insert plate 595 faces the side away from the front door body 56.

[0035] It should be noted that the shape of the insert plate 595 causes the front door body 56 to move slightly backward. This distance is provided by the gap between the connecting rod 58 and the guide rail 57 and between the guide rail 57 and the front door body 56. A rubber pad is provided on the rear side of the front door body 56 near the edge. After the front door body 56 moves slightly backward, the rubber pad is compressed, which improves the sealing performance of the front door body 56 to the hot press body 1.

[0036] like Figure 4 As shown, a guide groove 512 is provided on the rear side of the fixed plate 510 located on the lower side. Two sliders 513 are symmetrically distributed on the left and right sides and are movably sleeved on the inner side of the guide groove 512. The rear side of the sliders 513 is slidably connected to the front side of the lower mechanism plate 4. A second electromagnetic push plate 511 is fixedly connected to the side of the two sliders 513 that is far away from each other. The rear side of the second electromagnetic push plate 511 is fixedly connected to the front side of the lower mechanism plate 4.

[0037] It should be noted that the second electromagnetic push plate 511 can drive the slider 513 to move left and right. The two sliders 513 move in opposite directions, causing the sliders 513 to slide in the guide groove 512, which causes the fixed plate 510 to move up and down. This causes the fixed plate 510 to move slightly downward, which causes the connecting rod 58 to drive the guide rail 57 to move forward, so that the front door body 56 can open and close without causing interference between the front door body 56 and the lower fixed plate 510.

[0038] like Figure 5As shown, second springs 514 are movably installed on the left and right sides of the lower fixed plate 510 near the upper side and on the left and right sides of the front side of the lower mechanism plate 4 near the lower side.

[0039] It should be noted that the second spring 514 is a tension spring. When the sliders 513 move away from each other, the second spring 514 pulls the fixing plate 510 down so that it is close to the sliders 513.

[0040] The working principle of this utility model is as follows: First, the outer side of the transmission rod 53, near the left and right ends, is rotatably connected to the inner side of the rotating frame 3, providing support for the transmission rod 53. The motor 51 drives the transmission rod 53 to rotate, which in turn drives the storage wheel 54 to rotate. When the storage wheel 54 rotates, the traction belt 55 extends or retracts from the inner side of the storage wheel 54, thereby achieving the purpose of moving the front door body 56 up and down. A power component is provided between the connecting rod 58 and the mounting plate 2, which can drive the connecting rod 58 to rotate. When the connecting rod 58 rotates, the guide rail 57 moves back and forth, causing the guide rail 57 to drive the front door body 56 to move back and forth, thereby achieving the function of opening and closing the front door body 56. By driving the storage wheel 54 to rotate through the motor 51, the traction belt 55 moves up and down, and the connecting rod 58 drives the front door body 56 to move back and forth, realizing the up and down movement of the front door body 56 and... The front and rear opening and closing action is simple in structure, does not take up space, works stably, and has higher work efficiency. Finally, the first electromagnetic push rod 591 drives the first crossbar 592 to move up and down. When the first crossbar 592 moves up and down, it relies on the limit rod 593 to drive the second crossbar 594 to move up and down, thereby causing the insert plate 595 to move up and down. When the insert plate 595 is inserted into the inner side of the fixing plate 510, the fixing plate 510 fixes the front door body 56. The lower fixing plate 510 and the lower mechanism plate 4 are slidably connected in the vertical direction, and the upper fixing plate 510 and the upper mechanism plate 4 are fixedly connected. By inserting the insert plate 595 into the inner side of the fixing plate 510, the fixing plate 510 fixes the front door body 56, so that the front door body 56 will not shake as a whole due to the use of the traction belt 55 transmission, which would affect the sealing performance of the front door body 56 to the hot press body 1.
