Description

Technical Field

[0001] This invention belongs to the field of acrylic technology, specifically an acrylic shell molding and processing device and method. Background Technology

[0002] Acrylic material refers to pure polymethyl methacrylate, which has high transparency and light transmittance, as well as good surface hardness and gloss. It is highly malleable and can be made into various shapes and products. Acrylic shells require thermoforming. After thermoforming, the thermoformed acrylic shell needs to be ejected from the cavity of the mold. When the resistance of the acrylic shell sliding out of the cavity is large, the thrust of the ejector rod on the acrylic shell increases. Since the acrylic shell is thermoformed, the hardness is low when it is not fully cooled. When the thrust of the ejector rod on the acrylic shell is large, the acrylic shell is prone to leaving the ejector rod imprint. This requires secondary processing and has certain limitations.

[0013] The present invention also provides a method for forming acrylic shells, including the acrylic shell forming apparatus as described above, comprising the following steps:

[0014] Step 1: The staff calculates the required acrylic material, places the acrylic material in the cavity, heats it with a heating plate, and drives the second magnet block and the second iron plate to move down through the second elastic lifter so that the pressure plate is inserted into the cavity. At the same time, the pressure plate drives the bracket and the first slider to move down so that the first slider slides through the through hole into the first annular groove from the groove on the first support plate. The pressure plate presses the acrylic material in the cavity to heat-press the acrylic material in the cavity into an acrylic shell.

[0015] Step 2: After the acrylic shell is hot-pressed, the rotating support structure drives the carrier to rotate, so that the carrier and the mold flip. The mold drives the bracket and the first slider to move through the pressure plate located in the cavity, so that the first slider slides in the first annular groove. At the same time, the second iron plate and the second magnet block are no longer magnetically attracted, and the first movable plate, the ejector rod and the first iron plate rotate synchronously. The first magnet block is no longer magnetically attracted to the first iron plate. During the flipping process of the support plate and the mold, the first elastic lifter drives the first magnet block to move upward, so that the first magnet block moves to the preset height. At the same time, the second elastic lifter drives the second magnet block to move upward, so as to avoid the second magnet block interfering with the flipping of the first movable plate and the first iron plate.

[0016] Step 3: When the carrier and mold are rotated 180 degrees, the second iron plate moves above the first magnet and the two magnets attract each other. At the same time, the first iron plate moves below the second magnet and the two magnets attract each other. The pressure plate is located at the bottom of the acrylic shell. The second elastic lifter drives the second magnet and the first iron plate to move down, so that the first movable plate presses the acrylic shell in the cavity through the ejector rod. Under the combined action of its own weight and the pressure applied by the ejector rod, the acrylic shell slides out of the cavity. The first elastic lifter drives the first magnet, the second iron plate and the pressure plate to move down, so that the pressure plate moves down synchronously with the acrylic shell. At the same time, the pressure plate drives the bracket and the first slider to move down synchronously. The first slider slides from the first annular groove into the groove on the second support plate through the through hole. Finally, the acrylic shell is detached from the cavity.

[0017] Step 4: The worker removes the acrylic shell from the pressure plate, drives the first magnet block and the second iron plate to move up through the first elastic lifter, and the pressure plate drives the first slider to move again through the bracket, so that the first slider moves from the groove in the second support plate to the first annular groove through the through hole, and the pressure plate slides into the cavity. The carrier seat is driven to rotate through the rotating support structure, and the carrier seat and the mold are rotated 180 degrees again, so that the mold is rotated to the top of the carrier seat again. The second magnet block is driven to move down through the second elastic lifter, so that the second magnet block and the second iron plate are magnetically attracted to each other.

[0018] Step 5: Drive the second magnet block upward through the second elastic lifter, so that the second magnet block drives the pressure plate to detach from the cavity through the second iron plate. The pressure plate drives the first slider to move through the bracket, so that the first slider slides from the first annular groove through the through hole into the groove on the first support plate, so that the pressure plate returns to its initial height, and the next acrylic shell forming process can be carried out.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] (1) The staff calculates the required acrylic material, places the acrylic material in the cavity, heats it with a heating plate, and drives the second magnet and the second iron plate to move down through the second elastic lifting device so that the pressure plate is inserted into the cavity. At the same time, the pressure plate drives the bracket and the first slider to move down so that the first slider slides through the through hole into the first annular groove from the slide groove on the first support plate. The pressure plate presses the acrylic material in the cavity to heat-press the acrylic material in the cavity into an acrylic shell. After the acrylic shell is heat-pressed, the rotating support structure drives the carrier to rotate so that the carrier and the mold flip. The mold drives the bracket and the first slider to move through the pressure plate located in the cavity so that the first slider slides in the first annular groove. At the same time, the second iron plate... The first and second magnets no longer attract each other, and the first movable plate, ejector rod, and first iron plate rotate synchronously. The first magnet no longer attracts the first iron plate. During the rotation of the support plate and mold, the first elastic lifter drives the first magnet to move upward to a preset height. At the same time, the second elastic lifter drives the second magnet to move upward to avoid interference with the rotation of the first movable plate and the first iron plate. When the carrier and mold rotate 180 degrees, the second iron plate moves above the first magnet, and the second iron plate and the first magnet attract each other. At the same time, the first iron plate moves below the second magnet, and the first iron plate and the second magnet attract each other. The pressure plate is located at the bottom of the acrylic shell, and the second magnet and the first iron plate are driven by the second elastic lifter. The first movable plate moves downwards, causing the ejector rod to press the acrylic shell inside the cavity. Due to its own weight and the pressure applied by the ejector rod, the acrylic shell slides out of the cavity. The first elastic lifter drives the first magnet, the second iron plate, and the pressure plate downwards, so that the pressure plate moves downwards synchronously with the acrylic shell. Simultaneously, the pressure plate drives the bracket and the first slider downwards synchronously. The first slider slides through the through-hole from the first annular groove into the groove on the second support plate. Finally, the acrylic shell detaches from the cavity. The worker removes the acrylic shell from the pressure plate. The first elastic lifter then drives the first magnet and the second iron plate upwards. The pressure plate again drives the first slider to move through the through-hole into the groove on the second support plate. The mold moves into the first annular groove, and the pressure plate slides into the cavity. The rotating support structure drives the carrier to rotate, causing the carrier and mold to rotate 180 degrees again, so that the mold is above the carrier. The second elastic lifter drives the second magnet block downwards, causing it to magnetically attract the second iron plate. The second elastic lifter then drives the second magnet block upwards, causing it to drive the pressure plate out of the cavity via the second iron plate. The pressure plate, through the bracket, drives the first slider to move, allowing it to slide through the through-hole from the first annular groove into the groove on the first support plate, restoring the pressure plate to its initial height. The next acrylic shell molding process can then begin. Under the combined action of the acrylic shell's own weight and the pressure applied by the ejector rod...This allows the acrylic shell to detach from the cavity, reducing the force required to eject the acrylic shell from the cavity using ejector rods. This reduces the likelihood of ejector rod marks remaining on the acrylic shell, thus lowering the product rework rate.

[0021] (2) The second movable plate is driven to move vertically by the first hydraulic telescopic rod. The second movable plate is driven to move vertically by the first magnet block by the first spring. The design of the first spring makes the first magnet block and the second movable plate elastically connected. When the first iron plate and the first movable plate are flipped, the first magnet block can move relative to the second movable plate to avoid the first magnet block interfering with the flipping of the first iron plate. The position of the carrier is limited by two limiting plates to prevent the carrier from rotating due to non-human factors. When the carrier needs to rotate, the second hydraulic telescopic rod drives the first support part and the limiting plate to move so that the limiting plate no longer contacts the carrier, so that the carrier can rotate relative to the support plate. The third movable plate is driven to move vertically by the third hydraulic telescopic rod. The third movable plate is driven to move vertically by the second spring. The design of the second spring makes the second magnet block and the third movable plate elastically connected. When the second iron plate and the pressure plate are flipped, the second magnet block can move relative to the third movable plate to avoid the second magnet block interfering with the flipping of the second iron plate and the pressure plate.

[0022] (3) The second sprocket is driven to rotate by the motor. The second sprocket drives the first sprocket and the shaft to rotate through the chain. The shaft drives the carrier to rotate. When the carrier rotates, the carrier drives the second slider to rotate in the second annular groove through the connecting column. The design of the second annular groove, the second slider and the connecting column increases the stability of the carrier when it rotates.

[0023] (4) The design of the third guide post and the limiting plate allows the first movable plate and the ejector rod to move smoothly in the vertical direction relative to the carrier. The limiting plate supports the first movable plate and limits its position, thereby preventing the ejector rod from dislodging from the ejector hole. The operator drives the fourth movable plate to move, the third spring is in a stretched state, and the baffle no longer contacts the top of the second support part, releasing the limitation on the position of the second support part and the limiting ring. The operator drives the mold to move so that the limiting ring disengages from the insert block, thus completing the mold removal and facilitating the replacement of molds of different specifications. When the second magnet block and the second iron plate are magnetically attracted, the second elastic lifter drives the second magnet block and the second iron plate to move up. The pressure plate drives the first slider to move up through the bracket so that the first slider disengages from the groove on the first support plate. The operator drives the pressure plate to move so that the second iron plate no longer magnetically attracts the second magnet block, thus completing the pressure plate removal and facilitating the replacement of pressure plates of different specifications according to the mold.

A pressure plate 15 is provided above the mold 6, and a second iron plate 16 is fixedly connected to the top of the pressure plate 15. A second magnet block 17 is provided on the top of the second iron plate 16. The second magnet block 17 and the top plate 2 are connected by a second elastic lifter. Two brackets 18 are fixedly connected to the pressure plate 15, and a first slider 19 is fixedly connected to the brackets 18. Both the first support plate 13 and the second support plate 14 have openings for connection with the first slider. The slide groove 51 that matches the block 19 is provided on the support plate 5. The first annular groove 20 that matches the first slider 19 is provided on the first annular groove 20.

Under the dual action of the acrylic shell's own weight and the pressure applied by the ejector rod 10, the acrylic shell is detached from the cavity 7. This reduces the force required to eject the acrylic shell from the cavity 7 using the ejector rod 10, thereby reducing the possibility of residual ejector rod 10 marks on the acrylic shell and reducing the product rework rate.

[0038] Example 2, based on Example 1, is... Figure 2 , Figure 3 , Figure 4 and Figure 6The first elastic lifting device includes a second movable plate 22 disposed below the first magnet block 12.

Two support plates 5 are inserted through the limit plate 26, and a first support part 27 is fixedly connected to it. The first support part 27 and the support plate 5 are connected by a second hydraulic telescopic rod 28.

[0039] The second movable plate 22 is driven to move vertically by the first hydraulic telescopic rod 23. The second movable plate 22 is driven to move vertically by the first magnet block 12 by the first spring 25. The design of the first spring 25 allows the first magnet block 12 and the second movable plate 22 to be elastically connected. When the first iron plate 11 and the first movable plate 9 are flipped, the first magnet block 12 can move relative to the second movable plate 22, avoiding interference with the flipping of the first iron plate 11. The position of the carrier 4 is limited by two limiting plates 26 to prevent the carrier 4 from rotating due to non-human factors. When the carrier 4 needs to rotate, the second hydraulic telescopic rod 23...

[0040] Example 3, based on Example 1, is... Figure 2 , Figure 3 , Figure 5 and Figure 8The rotating support structure includes connecting columns 42 fixedly installed on both sides of the carrier 4. A second annular groove 40 is opened on the side of the two support plates 5 that are close to each other. A second slider 41 is fixedly connected to the end of the connecting column 42 away from the carrier 4, and the second slider 41 is located in the second annular groove 40. A rotating shaft 29 is fixedly connected to the carrier 4. The rotating shaft 29 passes through one of the support plates 5 and one of the side plates 3. A bearing is provided at the passage of the rotating shaft 29 and the side plate 3. The rotating shaft 29 and the side plate 3 are connected by a rotating unit. The rotating unit includes a first sprocket 31 fixedly installed at one end of the rotating shaft 29. A motor 30 is provided below the rotating shaft 29. The motor 30 is fixedly connected to one of the side plates 3. A second sprocket 32 ​​is fixedly connected to the output end of the motor 30. The second sprocket 32 ​​and the first sprocket 31 are connected by a chain 33.

[0041] The second sprocket 32 ​​is driven to rotate by the motor 30. The second sprocket 32 ​​drives the first sprocket 31 and the shaft 29 to rotate via the chain 33. The shaft 29 drives the carrier 4 to rotate. When the carrier 4 rotates, the carrier 4 drives the second slider 41 to rotate within the second annular groove 40 via the connecting column 42. The design of the second annular groove 40, the second slider 41 and the connecting column 42 increases the stability of the carrier 4 when it rotates.

[0042] Example 4, based on Example 1, is... Figure 2 , Figure 4 , Figure 7 , Figure 8 and Figure 9 The guide unit includes at least two third guide posts 38 fixedly installed at the bottom of the carrier 4. The bottom end of the third guide post 38 passes through the first movable plate 9, and the bottom end of the third guide post 38 is fixedly connected to a limiting plate 39.

[0043] The design of the third guide post 38 and the limiting plate 39 allows the first movable plate 9 and the ejector rod 10 to move smoothly vertically relative to the carrier 4. The limiting plate 39 supports the first movable plate 9, limiting its position and preventing the ejector rod 10 from disengaging from the ejection hole 50. When the operator drives the fourth movable plate 48 to move, the third spring 49 is in a stretched state, and the baffle 46 no longer contacts the top of the second support part 45, releasing the restriction on the position of the second support part 45 and the limiting ring 44. The operator then drives the mold 6 to move, causing the limiting ring 44 to disengage. Inserting block 43 allows for the removal of mold 6, facilitating the replacement of molds 6 with different specifications. When the second magnet block 17 and the second iron plate 16 are magnetically attracted, the second elastic lifter drives the second magnet block 17 and the second iron plate 16 to move upward. The pressure plate 15 drives the first slider 19 to move upward through the bracket 18, so that the first slider 19 disengages from the groove 51 on the first support plate 13. The operator drives the pressure plate 15 to move, so that the second iron plate 16 is no longer magnetically attracted to the second magnet block 17, thus completing the removal of the pressure plate 15 and facilitating the replacement of pressure plates 15 with different specifications according to mold 6.

[0044] This embodiment provides a method for molding and processing an acrylic shell, including the acrylic shell molding and processing apparatus described above, and comprising the following steps:

[0045] Step 1: The staff calculates the required acrylic material, places the acrylic material in the cavity 7, heats it through the heating plate 8, and drives the second magnet block 17 and the second iron plate 16 to move down through the second elastic lifter so that the pressure plate 15 is inserted into the cavity 7. At the same time, the pressure plate 15 drives the bracket 18 and the first slider 19 to move down so that the first slider 19 slides through the through hole 21 from the slide groove 51 on the first support plate 13 into the first annular groove 20. The pressure plate 15 presses the acrylic material in the cavity 7 so that the acrylic material in the cavity 7 is hot-pressed into an acrylic shell.

[0046] Step 2: After the acrylic shell is hot-pressed, the rotating support structure drives the carrier 4 to rotate, so that the carrier 4 and the mold 6 are flipped. The mold 6 drives the bracket 18 and the first slider 19 to move through the pressure plate 15 located in the cavity 7, so that the first slider 19 slides in the first annular groove 20. At the same time, the second iron plate 16 and the second magnet 17 are no longer magnetically attracted, and the first movable plate 9, the ejector rod 10 and the first iron plate 11 rotate synchronously. The first magnet 12 is no longer magnetically attracted to the first iron plate 11. During the flipping process of the support plate 5 and the mold 6, the first elastic lifter drives the first magnet 12 to move upward, so that the first magnet 12 moves to the preset height. At the same time, the second elastic lifter drives the second magnet 17 to move upward, so as to avoid the second magnet 17 interfering with the flipping of the first movable plate 9 and the first iron plate 11.

[0047] Step 3: When the carrier 4 and the mold 6 are rotated 180 degrees, the second iron plate 16 moves above the first magnet block 12, and the second iron plate 16 and the first magnet block 12 are magnetically attracted to each other. At the same time, the first iron plate 11 moves below the second magnet block 17, and the first iron plate 11 and the second magnet block 17 are magnetically attracted to each other. The pressure plate 15 is located at the bottom of the acrylic shell. The second elastic lifter drives the second magnet block 17 and the first iron plate 11 to move down, so that the first movable plate 9 presses the acrylic shell in the cavity 7 through the ejector rod 10. Under the combined action of its own weight and the pressure applied by the ejector rod 10, the acrylic shell slides out of the cavity 7. The first elastic lifter drives the first magnet block 12, the second iron plate 16 and the pressure plate 15 to move down, so that the pressure plate 15 moves down synchronously with the acrylic shell. At the same time, the pressure plate 15 drives the bracket 18 and the first slider 19 to move down synchronously. The first slider 19 slides from the first annular groove 20 through the through hole 21 into the sliding groove 51 on the second support plate 14. Finally, the acrylic shell is detached from the cavity 7.

[0048] Step 4: The worker removes the acrylic shell from the pressure plate 15, drives the first magnet block 12 and the second iron plate 16 to move upward through the first elastic lifter, and the pressure plate 15 drives the first slider 19 to move again through the bracket 18, so that the first slider 19 moves from the slide groove 51 on the second support plate 14 through the through hole 21 to the first annular groove 20, and the pressure plate 15 slides into the cavity 7. The rotating support structure drives the carrier 4 to rotate, and the carrier 4 and the mold 6 are rotated 180 degrees again, so that the mold 6 is rotated to the top of the carrier 4 again. The second magnet block 17 is driven to move downward through the second elastic lifter, so that the second magnet block 17 and the second iron plate 16 are magnetically attracted to each other.

[0049] Step 5: Drive the second magnet block 17 upward through the second elastic lifter, so that the second magnet block 17 drives the pressure plate 15 to disengage from the cavity 7 through the second iron plate 16. The pressure plate 15 drives the first slider 19 to move through the bracket 18, so that the first slider 19 slides from the first annular groove 20 through the through hole 21 into the slide groove 51 on the first support plate 13, so that the pressure plate 15 returns to its initial height, and the next acrylic shell molding process can be carried out.

At the same time, the pressure plate (15) drives the bracket (18) and the first slider (19) to move down so that the first slider (19) slides from the slide groove (51) on the first support plate (13) into the first annular groove (20) through the through hole (21). The pressure plate (15) presses the acrylic material in the cavity (7) so that the acrylic material in the cavity (7) is hot-pressed into an acrylic shell. Step 2: After the acrylic shell is hot-pressed, the rotating support structure drives the carrier (4) to rotate, so that the carrier (4) and the mold (6) flip. The mold (6) drives the bracket (18) and the first slider (19) to move through the pressure plate (15) located in the cavity (7), so that the first slider (19) slides in the first annular groove (20). At the same time, the second iron plate (16) and the second magnet (17) no longer attract each other magnetically, and the first movable plate (9), the ejector rod (10) and the first iron plate (11) rotate synchronously.

During the flipping process of the support plate (5) and the mold (6), the first elastic lifter drives the first magnet (12) to move upward, so that the first magnet (12) moves to the preset height. At the same time, the second elastic lifter drives the second magnet (17) to move upward, so as to avoid the second magnet (17) interfering with the flipping of the first movable plate (9) and the first iron plate (11). Step 3: When the carrier (4) and the mold (6) are rotated 180 degrees, the second iron plate (16) moves above the first magnet (12), and the second iron plate (16) and the first magnet (12) are magnetically attracted to each other.
