A thermoplastic material forming apparatus based on glass transition temperature

Abstract

This application provides a thermoplastic material molding device based on glass transition temperature, belonging to the field of thermoplastic materials. This thermoplastic material molding device based on glass transition temperature includes a worktable. The worktable is internally equipped with an ejector mechanism for lifting and lowering the lower mold, and a fixing mechanism to prevent the lower mold from wobbling. Through the ejector and fixing mechanisms, and by setting up three sets of placement components and lower molds, the first set of lower molds can be used for injection, the second set for pressing down, and the third set for removing material. The pressing device drives the lifting component downwards, ejecting the third set of lower molds. Simultaneously, two sets of clamping components fix the second set of lower molds, preventing wobbling during pressing. This solves the problem that after thermoplastic material is pressed and cured, it is difficult to remove the cured material from the lower mold.

Description

Technical Field

[0001] This application relates to the field of thermoplastic materials, and more specifically, to a thermoplastic material molding apparatus based on glass transition temperature. Background Technology

[0002] Thermoplastic material molding equipment based on glass transition temperature is a specialized device that utilizes the state changes of thermoplastic materials near their glass transition temperature (Tg) to achieve precision molding. Its core principle is to switch the material between a glassy state (rigid solid) and a highly elastic state (rubber state) by precisely controlling the temperature, thereby optimizing processing performance and improving product quality.

[0003] In existing technologies, thermoplastic materials are transformed into a soft rubber state by a heating device, then the material is injected into a mold by an injection device, and then the thermoplastic material is shaped by a pressing device. After that, the material returns to a glassy state by natural cooling.

[0004] However, existing thermoplastic material molding equipment based on glass transition temperature still has the following shortcomings in use: In existing thermoplastic material molding equipment, the lower mold is usually fixed in a certain position. After the thermoplastic material is pressed and molded, the cured material is not easy to remove from the lower mold. Utility Model Content

[0005] To overcome the above shortcomings, this application provides a thermoplastic material molding apparatus based on glass transition temperature, which aims to improve the problem that the cured material is not easy to remove from the lower mold after being pressed into a thermoplastic material.

[0006] This application provides a thermoplastic material molding device based on glass transition temperature, including a worktable, a heating device above the worktable, an injection device connected to the output end of the heating device, a pressing device above the worktable, an upper mold connected to the output end of the pressing device, a lower mold above the worktable, an ejection mechanism for driving the lower mold to rise and fall inside the worktable, and a fixing mechanism for preventing the lower mold from shaking inside the worktable.

[0007] The workbench is internally connected to a drive device. The output end of the drive device passes through the workbench and is connected to a turntable. Three sets of placement components are connected above the turntable. The lower mold is movably inserted into the placement components. A vertical plate is connected to the bottom of the lower mold.

[0008] In one specific implementation, the ejection mechanism includes a lifting member connected to one side of the pressing device, and one side of the lifting member is connected to multiple sets of first racks.

[0009] In the above implementation process, by setting up the lifting component, the lifting component can be moved up and down simultaneously when the pressing device drives the upper mold to press up and down.

[0010] In one specific implementation, a fifth gear is rotatably connected inside the worktable, the fifth gear meshes with a first rack, and a second sprocket is connected to one side of the fifth gear.

[0011] In the above implementation process, by setting the fifth gear, when the lifting component moves up and down, the first rack drives the fifth gear to rotate, thereby driving the second sprocket to rotate.

[0012] In one specific implementation, a first sprocket is rotatably connected inside the workbench, a first chain is meshed with the outer surfaces of the first sprocket and the second sprocket, and a second bevel gear is connected to one side of the first sprocket.

[0013] In the above implementation process, by setting the first chain, when the second sprocket rotates, the first sprocket is driven to rotate through the first chain transmission, thereby driving the second bevel gear to rotate.

[0014] In one specific implementation, the workbench is internally connected to a first housing, and a first screw is rotatably connected inside the first housing. The other end of the first screw passes through the first housing and is connected to a first bevel gear. The first bevel gear meshes with the outer surface of a second bevel gear. A first threaded seat is threadedly connected to the outer surface of the first screw. A movable component is connected to the top of the first threaded seat. One end of the movable component passes through the workbench and the turntable and is movably inserted into the interior of the placement component.

[0015] In the above implementation process, by setting the first screw, when the second bevel gear rotates, it can drive the first bevel gear to rotate, thereby driving the first screw to rotate, and driving the connected first threaded seat to move up and down. When the pressing mechanism drives the lifting component to move down, the moving component pushes out a set of lower molds inside the placement component, thereby making it easier to take out the material formed inside the lower mold.

[0016] In one specific implementation, the fixing mechanism includes multiple sets of second racks connected to the other side of the lifting member, and a sixth gear is rotatably connected inside the worktable.

[0017] In the above implementation process, by setting the second rack, the sixth gear can be driven to rotate when the lifting component moves.

[0018] In one specific implementation, the sixth gear meshes with the second rack, and a fourth sprocket is connected to one side of the sixth gear.

[0019] In the above implementation process, by setting the fourth sprocket, the fourth sprocket can be driven to rotate when the sixth gear rotates.

[0020] In one specific implementation, a third sprocket is rotatably connected inside the workbench, and a second chain is meshed with the outer surfaces of the third sprocket and the fourth sprocket. A fourth bevel gear is connected to one side of the third sprocket.

[0021] In the above implementation process, by setting up the second chain, when the fourth sprocket rotates, the third sprocket is driven to rotate through the transmission of the second chain, thereby driving the fourth bevel gear to rotate.

[0022] In one specific implementation, the workbench is internally connected to a second housing, and a bidirectional screw is rotatably connected inside the second housing. The other end of the bidirectional screw passes through the second housing and is connected to a third bevel gear, which meshes with the outer surface of a fourth bevel gear.

[0023] In the above implementation process, by setting up a bidirectional screw, the third bevel gear can be driven to rotate when the fourth bevel gear rotates, thereby driving the bidirectional screw to rotate.

[0024] In one specific implementation, the outer surface of the bidirectional screw is threaded with two sets of second threaded seats, and the top of the second threaded seats is connected to a clamping member.

[0025] In the above implementation process, by setting the second threaded seat, when the bidirectional screw rotates, it can drive the two sets of second threaded seats to move and adjust the distance between the two sets of second threaded seats. When the pressing device presses down, the two sets of clamping parts can fix a set of lower molds, so as to prevent the lower mold below from shaking when the pressing device presses down.

[0026] Compared with the prior art, the beneficial effects of this application are as follows: By setting up the ejection mechanism and the fixing mechanism, and by setting up three sets of placement parts and lower molds, the first set of lower molds can be used for injection, the second set of lower molds can be used for pressing down, and the third set of lower molds can be used for material removal. The pressing device drives the lifting parts to move downward, so that the third set of lower molds is ejected. At the same time, the second set of lower molds is fixed by two sets of clamping parts to prevent the second set of lower molds from shaking when pressing down. This solves the problem that after the thermoplastic material is pressed and molded, the cured material is not easy to remove from the lower mold. Attached Figure Description

Detailed Implementation

[0037] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0038] Please see Figure 1 This application provides a thermoplastic material molding apparatus based on glass transition temperature, including a worktable 1.

[0039] Please see Figure 1 , Figure 2 and Figure 3 A heating device 5 is provided above the worktable 1. The output end of the heating device 5 is connected to the injection device 12. A pressing device 6 is provided above the worktable 1. The output end of the pressing device 6 is connected to the upper mold 10. A lower mold 9 is provided above the worktable 1. An ejection mechanism 2 for driving the lower mold 9 to rise and fall is provided inside the worktable 1. A fixing mechanism 3 for preventing the lower mold 9 from shaking is provided inside the worktable 1.

[0040] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The output end of the drive device 7 passes through the workbench 1 and is connected to the turntable 4. Three sets of placement parts 8 are connected above the turntable 4. The lower mold 9 is movably inserted into the interior of the placement parts 8. The bottom of the lower mold 9 is connected to the vertical plate 11. The drive device 7 can drive the turntable 4 to rotate.

[0041] In a specific configuration, the ejection mechanism 2 includes a lifting member 201, which is connected to one side of the pressing device 6. Multiple sets of first racks 202 are connected to one side of the lifting member 201. By setting the lifting member 201, when the pressing device 6 drives the upper mold 10 to press up and down, the lifting member 201 can be moved up and down at the same time.

[0042] In a specific configuration, a fifth gear 208 is rotatably connected inside the workbench 1. The fifth gear 208 meshes with the first rack 202. A second sprocket 207 is connected to one side of the fifth gear 208. By setting the fifth gear 208, when the lifting member 201 moves up and down, the first rack 202 drives the fifth gear 208 to rotate, thereby driving the second sprocket 207 to rotate.

[0043] In a specific configuration, a first sprocket 205 is rotatably connected inside the workbench 1. A first chain 206 is meshed with the outer surfaces of the first sprocket 205 and the second sprocket 207. A second bevel gear 204 is connected to one side of the first sprocket 205. Through the arrangement of the first chain 206, when the second sprocket 207 rotates, the first sprocket 205 is driven to rotate through the transmission of the first chain 206, thereby driving the second bevel gear 204 to rotate.

[0044] In the specific configuration, the workbench 1 is internally connected to a first housing 2010. A first screw 2011 is rotatably connected inside the first housing 2010. The other end of the first screw 2011 passes through the first housing 2010 and is connected to a first bevel gear 203. The first bevel gear 203 meshes with the outer surface of a second bevel gear 204. A first threaded seat 2012 is threadedly connected to the outer surface of the first screw 2011. A movable component 209 is connected to the top of the first threaded seat 2012. One end of the movable component 209 passes through the workbench 1 and the turntable 4 and is movably inserted into the interior of the placement component 8. The first screw 2011, when the second bevel gear 204 rotates, drives the first bevel gear 203 to rotate, thereby driving the first screw 2011 to rotate and causing the connected first threaded seat 2012 to move up and down. When the pressing mechanism drives the lifting component 201 to move down, the movable component 209 pushes out a set of lower molds 9 inside the placement component 8, making it easier to retrieve the formed material inside the lower mold 9.

[0045] In a specific configuration, the fixing mechanism 3 includes multiple sets of second racks 301, which are connected to the other side of the lifting member 201. The worktable 1 is rotatably connected to a sixth gear 307. The second racks 301 enable the sixth gear 307 to rotate when the lifting member 201 moves.

[0046] In a specific configuration, the sixth gear 307 is meshed with the second rack 301, and a fourth sprocket 306 is connected to one side of the sixth gear 307. The fourth sprocket 306 can be driven to rotate when the sixth gear 307 rotates.

[0047] In a specific configuration, a third sprocket 304 is rotatably connected inside the workbench 1. A second chain 305 meshes with the outer surfaces of the third sprocket 304 and the fourth sprocket 306. A fourth bevel gear 303 is connected to one side of the third sprocket 304. The second chain 305 enables the third sprocket 304 to rotate when the fourth sprocket 306 rotates, thereby driving the fourth bevel gear 303 to rotate.

[0048] In a specific configuration, a second housing 3010 is connected inside the workbench 1. A bidirectional screw 3011 is rotatably connected inside the second housing 3010. The other end of the bidirectional screw 3011 passes through the second housing 3010 and is connected to a third bevel gear 302. The third bevel gear 302 is meshed with the outer surface of a fourth bevel gear 303. The bidirectional screw 3011 enables the third bevel gear 302 to rotate when the fourth bevel gear 303 rotates, thereby driving the bidirectional screw 3011 to rotate.

[0049] In a specific configuration, the outer surface of the bidirectional screw 3011 is threaded with two sets of second threaded seats 309. The top of the second threaded seats 309 is connected to a clamping member 308. The second threaded seats 309 can move the two sets of second threaded seats 309 when the bidirectional screw 3011 rotates. By adjusting the distance between the two sets of second threaded seats 309, a set of lower molds 9 can be fixed by the two sets of clamping members 308 when the pressing device 6 presses down, thus preventing the lower molds 9 from shaking when the pressing device 6 presses down.

[0050] The working principle of this thermoplastic material molding equipment based on glass transition temperature is as follows: By setting up three sets of placement components 8 and lower molds 9, the first set of lower molds 9 can inject material, the second set of lower molds 9 can press down, and the third set of lower molds 9 can remove material. After the thermoplastic material is injected into the lower molds 9, the rotation of the turntable 4 moves the material below the pressing device 6 for pressing. After this, the turntable 4 rotates to remove the molded material. The pressing device 6 drives the lifting component 201 to move downwards. The first rack 202 drives the fifth gear 208 to rotate, which in turn drives the second sprocket 207 to rotate. Then, the first chain 206 drives the first sprocket 205 to rotate, which in turn drives the second bevel gear 204 to rotate, which in turn drives the first bevel gear 203 to rotate, which in turn drives the first screw 2011 to rotate, thus driving the connected... The first threaded seat 2012 moves up and down. When the pressing mechanism drives the lifting component 201 to move down, the moving component 209 pushes out a set of lower molds 9 inside the placement component 8, making it easier to remove the material formed inside the lower mold 9. At the same time, through the second rack 301, the sixth gear 307 is driven to rotate, which drives the fourth sprocket 306 to rotate. Through the transmission of the second chain 305, the third sprocket 304 is driven to rotate, which drives the fourth bevel gear 303 to rotate, which in turn drives the third bevel gear 302 to rotate, thereby driving the bidirectional screw 3011 to rotate and causing the two sets of second threaded seats 309 to move. By adjusting the distance between the two sets of second threaded seats 309, a set of lower molds 9 can be fixed by two sets of clamping components 308 when the pressing device 6 presses down, preventing the lower mold 9 below from shaking when the pressing device 6 presses down. This solves the problem that the solidified material is not easy to remove from the lower mold 9 after the thermoplastic material is pressed and formed.

[0051] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
