Description

Technical Field

[0001] The utility model relates to an improved invention of a blister molding device, in particular to a pressing component of a blister molding mechanism. Background Art

[0002] After the plate is heated, it is transferred to the blister forming station for blister forming operation. During the blister forming operation, the molding cavity must be kept in a sealed state. After the mold frame with the plate is moved to the molding station, the mold frame is pressed down by the clamping frame to seal and press the mold frame with the upper end surface of the molding cylinder, so that the plate and the molding cavity of the molding cylinder form a closed space.

[0003] The lifting of the pressing frame is driven by a cylinder. When the cylinder is cut off, the pressing frame falls due to gravity. If the mold frame is in the forming station, the pressing frame will press on the mold frame and the mold frame cannot move. If the mold frame is in the heating station, the pressing frame will block the mold frame from entering the forming station. If the mold frame is in the heating station for a long time, the plate will sag, causing a fire, posing a great safety hazard. Summary of the invention

[0004] In view of the technical problems existing in the background technology, the technical problem solved by the utility model is to provide a pressing component of a blister forming mechanism with a floating protection function to prevent the pressing frame from affecting the movement of the mold frame.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: the pressing component of the blister forming mechanism is arranged above the blister forming station, and is characterized in that it includes a pressing frame, a cylinder and a floating assembly;

[0006] A cylinder is mounted on the frame, and a piston rod of the cylinder is connected to the pressing frame;

[0007] The floating assembly includes a guide column, a spring and a limit block. The lower end of the guide column is connected to the clamping frame, and the upper end of the guide column passes through the mounting plate and is connected to the limit block. The spring is sleeved outside the guide column and is arranged between the limit block and the mounting plate. The mounting plate is connected to the frame.

[0008] When the air cylinder is cut off, the clamping frame moves downward due to gravity, and the guide column moves downward relative to the mounting plate. The distance between the limit block and the mounting plate becomes smaller, and the spring is compressed. When the elastic force of the spring is equal to the gravity of the clamping frame, the clamping frame no longer moves downward and stays above the mold frame. In this way, the mold frame can move normally, eliminating safety hazards.

[0009] Preferably, the mounting plate is provided with a guide sleeve, wherein the guide sleeve is provided with a guide hole matching the guide post, and the guide sleeve guides the guide post to stably rise and fall.

[0010] Preferably, the upper end of the guide column is connected with an adjusting screw, the limit block is provided with a threaded hole, and the limit block is threadedly connected with the adjusting screw. The position of the limit block on the adjusting screw is adjusted to adjust the elastic force of the spring, so that the clamping frame stays at a desired position when the cylinder is de-energized.

[0011] Preferably, the pressing frame comprises a crossbeam and columns arranged at both ends of the crossbeam, and the bottom surface of the column is pressed with the mold frame;

[0012] The piston rod of the cylinder is connected to the crossbeam, and the floating assembly is provided with two groups and symmetrically arranged on both sides of the cylinder. The lifting is stable and the pressing is firm.

[0013] Preferably, the pressing frame is pressed together with the mold frame of the blister forming station;

The mold frame moves longitudinally between the heating station and the blister forming station along the linear guide rail.

[0015] Preferably, the mold frame includes an upper frame and a lower frame, and the lower frame is provided with a transparent observation window. At the heating station, the staff can observe the state of the plate during the heating condition through the observation window. If the plate sags to a critical point, the mold frame should be transferred to the forming station to avoid excessive sagging of the plate and cause fire. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following describes the relevant details and working principle of the implementation mode and embodiment of the utility model in conjunction with the accompanying drawings. The clamping component of the plastic forming mechanism is arranged above the plastic forming station, and the clamping component of the plastic forming mechanism includes a clamping frame 3, a cylinder 1 and a floating assembly 2; the cylinder is installed on the frame, and the piston rod of the cylinder 1 is connected to the clamping frame 3; the floating assembly includes a guide column 8, a spring 7 and a limit block 10, the lower end of the guide column is connected to the clamping frame 3, the upper end of the guide column 8 passes through the mounting plate 6 and is connected to the limit block 10, the spring 7 is sleeved outside the guide column 8 and is arranged between the limit block and the mounting plate, and the mounting plate 6 is connected to the frame; in order to make the guide column 8 rise and fall stably, the mounting plate is installed with a guide sleeve 5, and the guide sleeve 5 is provided with a guide hole matching the guide column 8, and the guide column rises and falls in the guide hole of the guide sleeve. The clamping frame 3 includes a crossbeam 11 and columns 12 arranged at both ends of the crossbeam, and the bottom surface of the column 12 is pressed against the mold frame 4; the piston rod of the cylinder 1 is connected to the crossbeam 11, and the floating assembly 2 is provided with two groups and symmetrically arranged on both sides of the cylinder. The cylinder drives the clamping frame 3 to press down, and the two columns 12 press the two sides of the mold frame 4 tightly, and the pressing is firm; the floating assembly 2 is symmetrically arranged, the elastic force is balanced, and the lifting is stable. The mold frame 4 moves longitudinally between the vacuum forming station and the heating station, and the frame is provided with a longitudinally arranged linear guide rail, and the linear guide rail is provided with a slider 15, and the slider is installed on the mold frame; the mold frame moves longitudinally between the heating station and the vacuum forming station along the linear guide rail. The mold frame 4 includes an upper frame 13 and a lower frame 14. The lower frame is provided with a transparent observation window 16. The upper frame and the lower frame are pressed together to clamp the plate. The mold frame 4 moves to the heating station. The plate is heated and softened. The staff can observe the state of the plate through the observation window 16. If the plate softens and sags to a critical point, the mold frame should be transferred to the molding station to avoid excessive sagging of the plate and cause a fire. After the plate is heated, the mold frame moves to the vacuum forming station, and the cylinder 1 drives the clamping frame 3 to move down. The cylinder overcomes the elastic force of the spring 7, and the column presses the mold frame so that the mold frame is sealed and pressed with the molding cylinder below; after the vacuum forming is completed, the cylinder drives the clamping frame to move up, the upper frame and the lower frame are separated, and the finished product is taken out. When the air cylinder is cut off, the clamping frame 3 moves downward due to gravity, the guide column 8 moves downward relative to the mounting plate 6, the spacing between the limit block 10 and the mounting plate 6 becomes smaller, and the spring 7 is compressed. When the elastic force of the spring is equal to the gravity of the clamping frame, the clamping frame no longer moves downward and stays above the mold frame, so that the mold frame can move longitudinally without being affected by the clamping frame. The elastic force of the spring will affect the height of the clamping frame's downward movement. The upper end of the guide column is connected to an adjusting screw 9, and the limit block 10 is provided with a threaded hole matching the adjusting screw. The limit block is threadedly connected to the adjusting screw. The position of the limit block 10 on the adjusting screw is adjusted to adjust the elastic force of the spring. The closer the limit block 10 is to the mounting plate 6, the more compressed the spring 7 is, and the greater the elastic force is. Conversely, the farther the limit block is from the mounting plate, the smaller the elastic force is.
