Description

Technical Field

[0001] This utility model relates to the field of acrylic sheet forming technology, and in particular to an acrylic sheet vacuum forming machine. Background Technology

[0002] Acrylic sheet is a transparent or translucent thermoplastic. Due to its high transparency, weather resistance, ease of processing, and aesthetics, it is often used as a substitute for glass. As a thermoplastic material, acrylic sheet can be heated and softened by a vacuum forming machine and then shaped to create complex three-dimensional shapes. A vacuum forming machine is a device that heats and softens plastic sheets and then uses vacuum adsorption to make them fit into a mold. The vacuum forming machine processes the heated and softened acrylic sheet into the required shape.

[0003] The acrylic sheet formed under vacuum reaches a high temperature, requiring experienced workers to remove it. Overloading the sheet during removal can cause burns from direct contact, and the strong adhesion between the vacuum-formed sheet and the mold makes removal laborious. Therefore, those skilled in the art have provided an acrylic sheet vacuum forming machine to address the problems mentioned in the background section. Utility Model Content

[0004] 1. Technical Solution

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a vacuum forming machine for acrylic sheets, comprising a base plate, a mounting frame, a rotating motor, a stroke cover, a mounting frame, a mold, and a stroke plate. The base plate has a mounting frame at its upper end, a hydraulic rod (first type) inside the mounting frame, a stroke cover at the lower end of the hydraulic rod, symmetrically distributed support plates at the upper end of the base plate, a mounting frame inside the support plates, a hydraulic rod (third type) inside the upper end of the mounting frame, a top plate at the lower end of the hydraulic rod (third type), and top rods arranged in a circular array at the upper end of the top plate. The mounting frame has a stroke plate inside, a mold at its upper end, a negative pressure pump on the inner wall of the upper end of the mold, and air holes arranged in a circular array inside the mold. Both ends of the mounting frame have rotating shafts rotatably mounted inside the support plates. One end of the support plate has a rotating motor with its output end connected to the rotating shaft. A vibration motor is installed on the inner wall of the mold.

[0007] Furthermore, a sealing ring arranged in a ring array is embedded inside the travel plate, the upper end of the push rod is slidably inserted into the sealing ring, and a top block is provided at the upper end of the push rod;

[0008] Specifically, the sealing ring allows the ejector pin to slide effectively longitudinally inside the stroke plate. The ejector pin receives sliding support when sliding, and the upper end of the ejector block is flush with the upper end of the stroke plate, which is used to eject the acrylic sheet formed on the outer wall of the mold.

[0009] Furthermore, porous nano-ceramics are embedded and installed inside the pores;

[0010] Specifically, porous nanoceramics allow gas to pass through during use and have sufficient strength to support softened acrylic sheets.

[0011] Furthermore, the mounting frame is provided with symmetrically distributed hydraulic rods two, the upper end of which is connected to the stroke plate;

[0012] Specifically, when the hydraulic rod drives the telescopic end to move longitudinally, it drives the stroke plate to move longitudinally and fits against the inner wall of the upper end of the mounting frame.

[0013] Furthermore, the upper end of the mounting frame is provided with a placement groove, an acrylic plate is provided inside the placement groove, and the lower end of the travel cover is provided with a pressure frame corresponding to the placement groove;

[0014] Specifically, the acrylic sheet is placed inside the upper part of the mounting frame through the placement groove, and the acrylic sheet is pressed on the sides by the pressure frame.

[0015] Furthermore, guide plates are provided at both ends of the travel cover, and guide rods that are symmetrically distributed and slidably inserted into the guide plates are provided between the mounting bracket and the base plate;

[0016] Specifically, when the travel cover moves longitudinally, it slides on the outer wall of the guide rod to guide the travel cover longitudinally.

[0017] Furthermore, a closing plate is provided inside the mold, and a sliding sleeve is embedded inside the closing plate, with the three lower ends of the hydraulic rod inserted into the sliding sleeve;

[0018] Specifically, the closing plate closes the lower end of the mold, while the three telescopic ends of the hydraulic rod are slidably supported through the sliding sleeve, driving the top plate to move longitudinally.

[0019] 2. Beneficial effects

[0020] Compared with existing technologies, the advantages of this utility model are:

[0021] In this invention, an acrylic sheet is placed inside a placement groove. The travel cover then moves longitudinally, causing a pressure frame to press against the edges of the acrylic sheet. After the acrylic sheet is heated and softened, the hydraulic rod drives the travel plate to adhere to the inner wall of the upper end of the mounting frame. During this process, the mold extrudes the softened acrylic sheet, causing it to expand. Negative pressure is used to draw air from between the mold and the acrylic sheet, allowing the acrylic sheet to adhere to the outer wall of the mold. After cooling, vacuum forming of the acrylic sheet is achieved. The travel cover then rises and resets. The mounting frame is driven by a rotating motor to rotate the shaft, causing the formed acrylic sheet to rotate. Under the action of the push rod, automatic unloading of the acrylic sheet is achieved, avoiding manual material handling, which requires extensive operational experience and carries risks of burns and laborious material handling. The forming of acrylic sheets is more convenient, and production safety is improved.

[0022] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0036] Example 1

[0037] Please see Figures 1-6As shown, this embodiment is an acrylic sheet vacuum forming machine, including a base plate 1, a mounting frame 2, a rotary motor 6, a stroke cover 8, a mounting frame 7, a mold 14, and a stroke plate 21. The base plate 1 has a mounting frame 2 at its upper end, a hydraulic rod 3 inside the mounting frame 2, and a stroke cover 8 at the lower end of the hydraulic rod 3. Symmetrically distributed support plates 25 are located at the upper end of the base plate 1, and the mounting frame 7 is located inside the support plates 25. A hydraulic rod 15 is located inside the upper end of the mounting frame 7, and a top cover is located at the lower end of the hydraulic rod 15. The top plate 17 has a top rod 22 arranged in a ring array at its upper end. The mounting frame 7 has a stroke plate 21 inside. The stroke plate 21 has a mold 14 at its upper end. The inner wall of the upper end of the mold 14 has a negative pressure pump 20. The mold 14 has air holes 19 arranged in a ring array inside its interior. Both ends of the mounting frame 7 have a rotating shaft 26 rotatably mounted inside the support plate 25. One end of the support plate 25 has a rotating motor 6 whose output end is connected to the rotating shaft 26. The inner wall of the mold 14 has a vibration motor 18.

[0038] The travel plate 21 has a sealing ring 23 arranged in a ring array embedded inside it. The upper end of the push rod 22 is slidably inserted into the sealing ring 23. A top block 24 is provided on the upper end of the push rod 22.

[0039] Porous nano-ceramics are embedded inside pore 19;

[0040] The mounting frame 7 is equipped with symmetrically distributed hydraulic rods 10, the upper ends of which are connected to the stroke plate 21.

[0041] The upper end of the mounting frame 7 has a placement groove 13 inside, and an acrylic plate 9 is placed inside the placement groove 13. The lower end of the travel cover 8 has a pressure frame 12 corresponding to the placement groove 13.

[0042] Guide plates 5 are provided at both ends of the travel cover 8, and guide rods 4 are symmetrically distributed and slidably inserted into the guide plates 5 between the mounting bracket 2 and the base plate 1.

[0043] The mold 14 has a closing plate 11 inside, and a sliding sleeve 16 is embedded inside the closing plate 11. The lower end of the hydraulic rod 15 is inserted into the sliding sleeve 16.

[0044] In this embodiment, when using the equipment, the acrylic sheet 9 to be formed is first placed in the placement groove 13 at the upper end of the mounting frame 7. The travel cover 8 moves longitudinally under the drive of the hydraulic rod 3, and the pressure frame 12 at its lower end presses and fixes the sides of the acrylic sheet 9. It is worth noting that a heating component is provided inside the travel cover 8. After the equipment is started, the heating component heats the acrylic sheet 9 evenly, softening it to a malleable state. At this time, the hydraulic rod 10 is activated, pushing the travel plate 21 upward to the inner wall of the upper end of the mounting frame 7. The mold 14 is tightly fitted to the outer wall of the softened acrylic sheet 9, which is then pressed to stretch and conform to the contour of the mold 14. Simultaneously, the negative pressure pump 20 inside the mold 14 is activated to draw air through the annular array of air holes 19. The output end of the negative pressure pump 20 passes through the closed plate 11, so that the acrylic sheet 9 is tightly adsorbed to the outer wall of the mold 14 under negative pressure. It is worth noting that the porous nano-ceramic material embedded in the air holes 19 not only ensures the smooth flow of gas channels, but also provides sufficient structural strength to support the softened sheet and prevent local collapse.

[0045] After molding, the equipment enters the cooling stage. After the acrylic sheet 9 is fully cured, the travel cover 8 is lifted and reset under the action of hydraulic rod 3, releasing the pressure on the sheet. At this time, the rotating motor 6 drives the rotating shaft 26 in the support plate 25 to rotate, causing the mounting frame 7 and the molded acrylic sheet 9 to rotate 180 degrees. The hydraulic rod 15 drives the top plate 17 to descend. Its ring-shaped push rods 22 pass through the sealing ring 23 and act precisely on the travel plate 21. The top block 24 pushes the molded part out evenly from the outer wall of the mold 14. At the same time, the vibration motor 18 operates, causing the mold 14 to vibrate, which helps the mold 14 to separate from the acrylic sheet 9. The design of the sealing ring 23 not only ensures the stability of the longitudinal sliding of the push rod 22, but also prevents heat loss from affecting the molding accuracy. At the same time, it avoids negative pressure from acting on the outside through the sealing ring 23. The entire feeding process is fully automated from molding to demolding through the coordinated control of the hydraulic system and the mechanical structure.

[0046] The fully automated feeding system eliminates the risk of manual contact with high-temperature molded parts, avoids the difficulty of manually picking up materials due to the adhesion and fastening of the molded acrylic sheet 9, reduces labor costs, and improves the efficiency of acrylic sheet 9 molding and processing.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0048] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
