An anti-accidental contact device is provided on the upper surface of the fixing device. The rotating wheel device changes the gap between the fixing device and the positioning rod device, thereby enabling the positioning rod device to slide and be fixed within the fixing device. The anti-accidental contact device can provide safety and accuracy assurance for the operator and production when the blister mold positioning is completed.

[0004] When using the above technology, the following technical problems were found in the existing technology: the existing positioning device is not convenient for fixing molds of different sizes. Therefore, a mold positioning device based on vacuum forming production is designed to provide another technical solution to the above technical problems. Utility Model Content

[0005] Therefore, it is necessary to provide a mold positioning device based on thermoforming production to address the above-mentioned technical problems, in order to solve the technical problem that existing positioning devices are not convenient for fixing molds of different sizes during use.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A mold positioning device based on thermoforming production includes a support base. Both ends of the top of the support base are provided with fixed plates. Anti-slip extrusion pads are fixed to the adjacent ends of the two fixed plates. A positioning mechanism for driving the two fixed plates to move in opposite directions is installed on the support base. The positioning mechanism includes a timing frame. The timing frame is slidably connected to the inside of both sides of the support base. The top end of the timing frame is slidably connected to the fixed plate.

[0008] As a preferred embodiment of the mold positioning device based on thermoforming production provided by this utility model, the bottom of the two anti-slip extrusion pads at adjacent ends are provided with inclined surfaces.

[0009] In a preferred embodiment of the mold positioning device based on thermoforming production provided by this utility model, the top of the fixed plate is internally threaded with a positioning bolt, and the positioning bolt is slidably connected to the timing frame.

[0010] As a preferred embodiment of the mold positioning device based on thermoforming production provided by this utility model, the positioning mechanism includes a synchronization plate, a clamping drive motor, a drive gear and a displacement rack. The clamping drive motor is fixed inside the support base. The output end of the clamping drive motor is connected to the drive gear. Displacement racks are meshed on both sides of the drive gear. The end of the displacement rack away from the drive gear is fixed with a synchronization plate. The synchronization plate is fixed to the synchronization frame.

[0011] In a preferred embodiment of the mold positioning device based on thermoforming production provided by this utility model, an adjustment mechanism is installed on both sides of the support base. The adjustment mechanism includes a pusher, a positioning frame, a pressure plate, a limiting plate, a limiting guide post, and a compression spring. Pushers are fixed at both ends of both sides of the support base. The push rods of the two pushers on the same side are connected to the positioning frame. A pressure plate is provided on the inner side of the adjacent side of the two positioning frames. The two ends of the top of the pressure plate are threadedly connected to the limiting guide post.

[0015] At the same time, through the above technical solutions, this utility model has at least the following beneficial effects:

[0016] This utility model provides a mold positioning device based on blister production. Through the cooperation of a support base, a fixing plate and an anti-slip extrusion pad, when the blister mold is placed on top of the support base, the two fixing plates are close together and the elasticity of the anti-slip extrusion pad can fix blister molds of different widths or lengths, thus providing greater adaptability.

[0017] Through the cooperation of the timing frame, timing plate, drive gear and displacement rack, the rotation of the drive gear can drive the two clamping drive motors to move in opposite directions, and the timing plate can drive the fixed plate to move through the timing frame.

[0018] By using the pusher, positioning frame, and pressure plate, the plastic sheet to be vacuum-formed can be fixed between the bottom of the pressure plate and the positioning frame. The pusher then moves the positioning frame to lower the plastic sheet and fit it into the vacuum forming mold. Finally, the vacuum pump connected to the vacuum forming mold works to press the heated plastic sheet into the mold, thus completing the vacuum forming process. Attached Figure Description

[0027] 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.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] Example 1

[0032] Reference Figures 1-5 A mold positioning device based on thermoforming production includes a support base 1. Both ends of the top of the support base 1 are provided with fixing plates 2. Anti-slip extrusion pads 4 are fixed at adjacent ends of the two fixing plates 2. The anti-slip extrusion pads 4 are made of elastic materials such as rubber. When the anti-slip extrusion pads 4 come into contact with the thermoforming mold, they can prevent the thermoforming mold from moving and prevent scratches on the outer side of the thermoforming mold. The bottom of the adjacent ends of the two anti-slip extrusion pads 4 are provided with inclined surfaces. When the fixing plates 2 move closer to the thermoforming mold, the closer the fixing plates 2 are to the thermoforming mold, the greater the extrusion force on the anti-slip extrusion pads 4, which can make the thermoforming mold more securely fixed between the two fixing plates 2.

[0033] A positioning mechanism for driving two fixed plates 2 to move in opposite directions is installed on the support base 1. The positioning mechanism includes a timing frame 3, a timing plate 5, a clamping drive motor 6, a drive gear 7, and a displacement rack 8. The timing frames 3 are slidably connected to the inside of both ends of the support base 1. The timing frames 3 are U-shaped. The top end of the timing frame 3 is slidably connected to the fixed plate 2, so that the fixed plate 2 can be detached and replaced by sliding on the two timing frames 3 at the same end. The top of the fixed plate 2 is threaded with a positioning bolt, and the positioning bolt is slidably connected to the timing frame 3, so that after the fixed plate 2 is slidably assembled on one end of the timing frame 3, it is fixed in position by the positioning bolt to prevent it from falling off.

[0034] A clamping drive motor 6 is fixed inside the support base 1. The output end of the clamping drive motor 6 is connected to a drive gear 7. Both sides of the drive gear 7 are meshed with displacement racks 8, so that the rotation of the drive gear 7 can drive the two displacement racks 8 to move in opposite directions. A synchronization plate 5 is fixed to the end of the displacement rack 8 away from the drive gear 7. The synchronization plate 5 is fixed to the synchronization frame 3, so that the movement of the displacement rack 8 drives the movement of the synchronization frame 3 through the synchronization plate 5. At the same time, each displacement rack 8 can slide through the unconnected synchronization plate 5, so that when the two synchronization plates 5 are close together, it does not hinder the movement of the unconnected displacement rack 8.

[0035] The usage process of the mold positioning device based on blister production provided by this utility model is as follows: In use, the blister mold is first placed on the top of the support base 1. Then, the operation of the clamping drive motor 6 drives the drive gear 7 to rotate, which in turn drives the meshing displacement rack 8 to move. The two displacement racks 8 move in opposite directions, causing the synchronous plates 5 to move synchronously. The two synchronous plates 5 move closer together, which in turn drives the fixed plate 2 to move through the synchronous frame 3. The movement of the fixed plate 2 causes the anti-slip extrusion pad 4 to move closer to the blister mold. The two fixed plates 2 move closer to the blister mold, allowing the anti-slip extrusion pad 4 to contact and extrude pressure on the surface of the blister mold, thereby positioning the blister mold and preventing movement. When the blister mold needs to be replaced, simply drive the drive motor 6 to rotate the drive gear 7 in the opposite direction. After multiple uses, the positioning bolts on the fixed plate 2 can be removed as needed to detach the fixed plate 2 from the synchronous frame 3 for replacement.

[0036] Example 2

[0037] Reference Figure 1 , Figure 2 and Figure 6A mold positioning device based on vacuum forming production is disclosed. An adjustment mechanism is installed on both sides of a support base 1. This mechanism lowers the plastic forming plate to contact the top of the vacuum forming mold. The adjustment mechanism includes a pusher 9, a positioning frame 10, a pressure plate 11, a limiting plate 12, a limiting guide post 13, a compression spring 14, and a pressing bolt 15. Pushers 9 are fixed to both ends of both sides of the support base 1. The push rods of two pushers 9 on the same side are connected to the positioning frame 10, allowing the operation of the two pushers 9 on the same side to simultaneously adjust the height of the corresponding positioning frame 10. The positioning frame 10 is U-shaped.

[0038] Preferably, the pusher 9 can be a push rod motor, cylinder or hydraulic cylinder, etc., used to drive the positioning frame 10 to perform lifting and adjustment.

[0039] In this embodiment, the push rod of the pusher 9 and the positioning frame 10 are slidably connected, which allows the positioning frame 10 to move closer to or further away from the blister mold by sliding on the push rod of the pusher 9. This causes the plastic sheet to descend inside the positioning frame 10 and contact the top of the blister mold. After processing is completed, the plastic sheet can be removed from the positioning frame 10 by pulling the positioning frame 10 to move it away from the blister mold.

[0040] Each of the two positioning frames 10 has a pressure plate 11 on its inner side on an adjacent side. The bottom of each end of the pressure plate 11 has an extrusion surface. When the bottom of the pressure plate 11 contacts the positioning frame 10, the plastic plate can be lifted by the extrusion surface, so that the plastic plate is located between the bottom of the pressure plate 11 and the positioning frame 10. The top ends of the pressure plate 11 are threadedly connected to limit guide posts 13. The outer side of the top of the limit guide post 13 is slidably connected to the positioning frame 10, so that the lifting and lowering of the pressure plate 11 inside the positioning frame 10 drives the limit guide post 13 to slide and lift within the positioning frame 10. At the same time, the pressure plate 11 can be separated from the limit guide post 13 by the threaded connection between the limit guide post 13 and the pressure plate 11, so that the pressure plate 11 can be separated from the positioning frame 10.

[0041] A limiting plate 12 is provided on the inner side of the positioning frame 10 and on top of the pressure plate 11. The inner side of the limiting plate 12 is slidably connected to the limiting guide post 13, so that the limiting guide post 13 can slide and rise and fall on the inner side of the limiting plate 12. Similarly, the limiting plate 12 can slide and rise and fall on the outer side of the limiting guide post 13. Compression springs 14 are evenly distributed and fixed between the limiting plate 12 and the pressure plate 11, so that the rise of the pressure plate 11 drives the compression springs 14 to compress. A compression bolt 15 is threadedly connected to the inner side of the top of the positioning frame 10, so that the height of the limiting plate 12 inside the positioning frame 10 can be limited by the bottom of the compression bolt 15.

[0042] The usage process of the mold positioning device based on thermoforming production provided by this utility model is as follows: During use, according to the required extrusion strength, rotate the extrusion bolt 15, allowing the extrusion bolt 15 to be threadedly connected to the positioning frame 10. Adjust the height of the bottom of the extrusion bolt 15 inside the positioning frame 10, thereby limiting the height of the limiting plate 12 when the bottom of the extrusion bolt 15 contacts the top of the limiting plate 12. The closer the limiting plate 12 is to the pressure plate 11, the stronger the extrusion force of the compression spring 14 between the limiting plate 12 and the pressure plate 11, thus limiting the height of the limiting plate 12 when it contacts the top of the positioning frame. The stronger the extrusion pressure between 10, the more firmly the plastic sheet can be extruded. Then, after the vacuum forming mold is positioned on the top of the support base 1, the plastic sheet enters through the extrusion surfaces at the bottom of both ends of the pressure plate 11, causing the pressure plate 11 to rise after being extruded and drive the compression spring 14 to compress. When both sides of the plastic sheet are completely inside the two positioning frames 10, the pressure plate 11 drops due to the rebound force after being compressed by the compression spring 14, positioning the plastic sheet. Then, the operation of the pusher 9 drives the positioning frame 10 to drop, causing the positioning frame 10 to drop and bring the plastic sheet into contact with the top of the vacuum forming mold.

[0043] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
