Description

Technical Field

[0001] The present application relates to the technical field of rubber and plastic molding, and in particular to a rubber and plastic molding device. Background Art

[0002] Injection molds are required for the injection molding of rubber and plastic materials. Injection molds are mostly composed of two parts: an upper mold and a lower mold. The upper mold and the lower mold together form a mold cavity for the injection molding of the rubber and plastic body. After the injection molding is completed, the injection mold needs to be cooled for a period of time before the injection mold can be separated and the injection molded part can be demolded and taken out. However, after the rubber and plastic body is cooled, due to volume shrinkage, it will partially adhere to the inner surface of the mold cavity. The operator needs to exert a certain amount of force to successfully separate the injection mold, resulting in high labor intensity for the operator, and it is inconvenient to remove the rubber and plastic body after molding, which needs to be improved. Utility Model Content

[0003] Based on this, the present application provides a rubber-plastic molding device, which can automatically complete the mold opening operation of the injection mold after the rubber-plastic body is molded, so as to facilitate the rapid demolding of the rubber-plastic body.

[0004] The rubber and plastic molding device provided in this application adopts the following technical solution:

[0005] A rubber and plastic molding device comprises a device body, a mold frame mechanism and a flap mechanism; wherein the mold frame mechanism comprises a bottom plate slidably connected to the device body, a pressing plate hinged to the bottom plate at one side, and a driving assembly for driving the bottom plate and the pressing plate to move together, the bottom plate is used to fix the lower mold of the mold, and the pressing plate is used to fix the upper mold of the mold;

[0006] The device body has a forming station and a material-retrieving station. The driving component normally forces the mold frame mechanism to be in the forming station; the flipping mechanism is arranged at the material-retrieving station and is located outside the pressure plate. When the driving component is activated, the pressure plate flips away from the bottom plate under the action of the flipping mechanism.

[0007] By adopting the above-mentioned technical scheme, the present application installs the upper mold on the bottom surface of the pressure plate and the lower mold on the surface of the bottom plate. When the mold frame mechanism is located at the molding station, the pressure plate rotates toward the bottom plate under the action of its own gravity, and the upper mold and the lower mold can approach each other to form a mold cavity and provide smooth injection molding of the rubber and plastic body; after the injection molding is completed, the mold frame mechanism is driven to enter the material taking station by controlling the action of the driving component, and the pressure plate can automatically flip in the direction away from the bottom plate under the action of the flipping mechanism, thereby realizing the automatic separation of the upper mold and the lower mold, which can facilitate the rapid demolding of the rubber and plastic body and reduce the labor intensity of the operators.

[0008] Optionally, side supports are respectively provided on both sides of the material picking station of the device body, and the flipping mechanism includes two guide rails symmetrically arranged on the side supports, and the height from the guide rails to the device body gradually increases from one end of the guide rails close to the forming station to the other end; guide blocks are respectively provided on the two opposite sides of the pressure plate, and when the driving assembly is actuated, the guide blocks abut against the top of the guide rails.

[0009] By adopting the above-mentioned technical solution, when the driving assembly is activated to drive the mold frame mechanism to enter the material picking station, the guide block can abut against the top of the guide rail and move upward along the rising direction of the guide rail, thereby causing the pressure plate to rotate around the rotating connection between itself and the bottom plate, so as to realize automatic flipping of the pressure plate and automatic separation of the upper mold and the lower mold.

[0010] Optionally, the flap mechanism further includes a limiting track arranged on the side support, wherein the limiting track is located above the guide track and is spaced apart from the guide track.

[0011] By adopting the above-mentioned technical solution, when the driving mechanism drives the mold frame mechanism to move toward the material picking station, the guide block abuts against the top surface of the guide rail and may jump during the movement, thereby causing the pressure plate to jump; the setting of the limit rail can play a limiting role when the pressure plate jumps, reducing the possibility of the pressure plate flipping over and eventually hitting the surface of the device body, thereby ensuring the safety of operation.

[0012] Optionally, the side support is equipped with a sensor component for stopping the pressure plate from being positioned, and the sensor component is electrically connected to the drive component through the control module; when the state of the sensor component changes, the drive component stops moving.

[0013] By adopting the above-mentioned technical solution, the sensor component is configured to detect the moving position of the pressure plate. After the pressure plate is flipped upward to be located outside the sensor component, the state of the sensor component can be changed, and then a signal is sent to the control module to control the drive component to stop the action, thereby maintaining the open state of the pressure plate and the bottom plate to facilitate the rapid demolding of the rubber and plastic body.

[0014] Optionally, the device body is provided with a pressing mechanism for forcing the upper mold and the lower mold to fit together during injection molding; a plurality of exhaust springs are provided between the bottom plate and the pressure plate, and when the pressing mechanism is actuated, the exhaust springs are in a compressed state.

[0015] By adopting the above technical solution, when the mold frame mechanism is in the molding station, by controlling the action of the pressing mechanism, the pressing mechanism can force the pressing plate to move downward for a certain distance, so that the upper mold and the lower mold of the mold are tightly molded and form a closed mold cavity; after the rubber and plastic parts are molded, by resetting the pressing mechanism, the pressing plate can automatically move upward for a certain distance under the elastic force of the exhaust spring, and then the gas inside the mold cavity can be discharged, so as to facilitate the subsequent smooth flipping of the pressing plate, and then successfully complete the mold opening operation of the injection mold.

[0016] Optionally, the pressure plate is hinged to the base plate on one side through a hinge structure, the hinge structure includes a fixed support fixed to the base plate and a rotating block rotatably mounted on the side edge of the pressure plate, a plug-in column is provided on the top of the fixed support, the rotating block is provided with a plug-in hole passing through both sides of the rotating block, and the plug-in column is matched and plugged into the plug-in hole.

[0017] By adopting the above-mentioned technical solution, the rotating block can be smoothly installed on the fixed support through the plug-in fit between the plug-in column and the plug-in hole, and under this plug-in fit mode, the pressing plate can move downward along the plug-in column when the pressing mechanism moves downward; in addition, when the driving assembly drives the mold frame mechanism to move to the material picking station, the pressing plate can rotate around the rotating block, thereby causing the pressing plate to flip in the direction away from the bottom plate.

[0018] Optionally, the drive assembly includes a linear drive component fixed to the device body and a lock connected to the movable end of the linear drive component, and the lock is provided with a sleeve groove; a ball shaft is fixed on the side edge of the base plate, the lock is sleeved on the ball shaft through the sleeve groove, and the ball shaft is threadedly connected with a limit member for limiting the detachment of the lock.

[0019] By adopting the above-mentioned technical solution, by connecting the lock to the movable end of the linear drive member, the lock's sleeve groove is sleeved on the ball shaft at the side edge of the base plate, and then the limiter is threadedly connected to the ball shaft to limit the lock from detaching from the ball shaft, the connection between the drive assembly and the base plate can be quickly completed, and it is also convenient for disassembly, maintenance or cleaning.

[0020] Optionally, the pressing plate is provided with a plurality of waist-shaped holes for fixing the upper die of the mold, and each waist-shaped hole is symmetrically arranged on each diagonal line of the pressing plate.

[0021] By adopting the above-mentioned technical solution, by passing the fasteners through the waist-shaped holes and fixing them to the upper mold of the mold, since the waist-shaped holes are symmetrically arranged on each diagonal of the pressing plate, the relative position of the upper mold of the mold and the pressing plate can be easily adjusted, and then the upper mold of the mold can be adjusted to a state of matching and fitting with the lower mold of the mold to ensure the smooth molding of the rubber and plastic body.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By setting up a flap mechanism, the driving assembly moves to drive the mold frame mechanism to enter the material taking station. The pressing plate can automatically flip away from the bottom plate under the action of the flap mechanism, thereby realizing the automatic separation of the upper mold and the lower mold, which can facilitate the rapid demoulding of the rubber and plastic body;

[0024] 2. By setting the sensor component, when the pressing plate is turned upward to the outside of the sensor component, the state of the sensor component can change, and then send a signal to the control module to control the driving component to stop the action, so that the opening state of the pressing plate and the bottom plate can be maintained, so as to facilitate the rapid demoulding of the rubber and plastic body;

[0025] 3. By setting the exhaust spring, after the rubber and plastic parts are formed, the pressing mechanism is reset, and the pressing plate can automatically move upward for a distance under the elastic force of the exhaust spring, so that the gas inside the mold cavity can be discharged, so that the subsequent pressing plate can be smoothly turned over, and the mold opening operation of the injection mold can be successfully completed.

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] The embodiment of the present application discloses a rubber and plastic molding device.

[0033] Reference Figure 1 A rubber and plastic molding device comprises a device body 1, a mold frame mechanism and a flap mechanism 2; wherein the mold frame mechanism comprises a bottom plate 3, a pressing plate 4 and a driving assembly 5; the device body 1 is fixed with a horizontally arranged slide rail 15, and at the same time, Figure 2 A slider 34 is fixed to the bottom surface of the bottom plate 3. The bottom plate 3 can be slidably connected to the device body 1 through the sliding cooperation between the slider 34 and the slide rail 15. An L-shaped hole 35 is opened on the surface of the bottom plate 3. The lower mold of the mold can be fixed to the surface of the bottom plate 3 by using fasteners such as bolts and the L-shaped hole 35.

[0034] Reference Figure 3 , a hinge structure 6 is provided between the pressing plate 4 and the bottom plate 3, and the pressing plate 4 can be hinged to the bottom plate 3 on one side through the hinge structure 6; specifically, the hinge structure 6 includes a fixed support 61 and a rotating block 62, and the fixed support 61 is fixed to the surface of the bottom plate 3 and is located at the side edge of the bottom plate 3; a plug-in column 611 is fixed to the top of the fixed support 61. An extension seat 43 is fixed to the side of the pressing plate 4, and the rotating block 62 is rotatably connected to the extension seat 43 through a rotating shaft; the rotating block 62 is provided with a plug-in hole 621, and the plug-in hole 621 passes through two opposite sides of the rotating block 62, and the outer diameter of the plug-in column 611 is equal to the inner diameter of the plug-in hole 621, and the pressing plate 4 can be rotated relative to the bottom plate 3 by matching and inserting the plug-in column 611 into the plug-in hole 621.

[0035] Back to Figure 2 The bottom surface of the pressing plate 4 is provided with a plurality of waist-shaped holes 42, each waist-shaped hole 42 penetrates the top surface of the pressing plate 4; in this embodiment, there are four pressing plates 4, and the four waist-shaped holes 42 are symmetrically arranged on each diagonal line of the pressing plate 4; bolts and other fasteners are used to cooperate with the waist-shaped holes 42 to fix the upper mold of the mold to the bottom surface of the pressing plate 4. The relative position of the upper mold of the mold and the lower mold of the mold can be conveniently adjusted by setting the waist-shaped holes 42 and the L-shaped holes 35, which is conducive to adjusting the upper mold of the mold to a state of matching and fitting with the lower mold of the mold, so as to ensure the smooth molding of the rubber-plastic body.

[0036] An exhaust spring 31 is fixed on the surface of the bottom plate 3. When the lower mold of the mold is fixed to the bottom plate 3, the exhaust spring 31 will be located on the outside of the lower mold of the mold. In the initial state, the pressure plate 4 can naturally rotate under the action of its own gravity to rest against the top of the exhaust spring 31. At this time, there is a gap between the upper mold and the lower mold of the mold.

[0037] Back to Figure 3The driving assembly 5 includes a linear driving member 51 fixed to the device body 1 and a lock 52 connected to the movable end of the linear driving member 51, wherein the linear driving member 51 is a cylinder; the lock 52 is provided with a sleeve groove 521, and the sleeve groove 521 passes through two opposite sides of the lock 52. A ball shaft 32 is fixedly mounted on the side edge of the bottom plate 3, and the outer diameter of the ball shaft 32 is equal to the inner diameter of the sleeve groove 521; a stud is fixedly connected to the middle of the ball shaft 32, and the stud is threadedly connected to the limit member 33; when the sleeve groove 521 of the lock 52 is sleeved on the ball shaft 32, the limit member 33 is threadedly connected to the stud, which can reduce the occurrence of the lock 52 being separated from the ball shaft 32, thereby maintaining the stable connection between the lock 52 and the bottom plate 3. It should be noted that the limit member 33 in this embodiment is a nut, which can be threadedly sleeved on the stud.

[0038] Back to Figure 1 The device body 1 has a molding station 11 and a material taking station 12. When the linear driving member 51 is in a normal state, the mold frame mechanism can be located at the molding station 11; and when the linear driving member 51 is in motion, it can push the mold frame mechanism to move to the material taking station 12.

[0039] The device body 1 is also fixed with a pressing mechanism 13 and a side support 14. The pressing mechanism 13 is located above the molding station 11. The pressing mechanism 13 includes a movable pressing seat 131 and a pressing cylinder 132. By controlling the action of the pressing cylinder 132, the movable pressing seat 131 can be moved downward and abutted against the pressing plate 4. Finally, the pressing plate 4 can move downward and force the upper mold of the mold to abut against the lower mold of the mold. At this time, injecting rubber or plastic into the mold cavity can enable the rubber body to be smoothly injection molded.

[0040] After the rubber-plastic body is injection molded, the downward pressure cylinder 132 is controlled to reset and drive the movable pressure seat 131 to reset upward. The pressure plate 4 can automatically move upward under the elastic force of the exhaust spring 31, thereby automatically separating the upper mold from the lower mold and discharging the gas inside the mold cavity, which is beneficial to the subsequent rapid demolding of the rubber-plastic body.

[0041] There are two side supports 14, which are respectively located at two opposite sides of the material taking station 12 and are used to install the flipping mechanism 2. The flipping mechanism 2 includes a guide rail 21 and a limit rail 22. There are two guide rails 21, which are respectively fixed to opposite sides of the two side supports 14; the guide rails 21 are extended in an arc shape, and the height of each guide rail 21 to the device body 1 gradually increases from one end of the guide rail 21 close to the forming station 11 to the other end.

[0042] Also refer to Figure 2, guide blocks 41 are fixed to two opposite sides of the pressing plate 4, and the guide blocks 41 are along the moving direction of the bottom plate 3 and face the guide rail 21; when the linear driving member 51 drives the bottom plate 3 to enter the material taking station 12, the guide blocks 41 can abut against the top of the guide rail 21 and automatically move upward under the guidance of the guide rail 21, so that the pressing plate 4 automatically flips away from the bottom plate 3, so that the upper mold and the lower mold of the mold are separated from each other, as shown in FIG. Figure 4 shown.

[0043] Back to Figure 1 A sensor component 7 is installed on the side of the side support 14 away from the linear drive member 51. The sensor component 7 in this embodiment can be various sensors such as infrared sensors and proximity switches. The sensor component 7 is electrically connected to the linear drive member 51 through the control module; when the linear drive member 51 drives the bottom plate 3 to enter the material taking station 12 and the pressing plate 4 flips in the direction away from the bottom plate 3, the pressing plate 4 can eventually be partially located outside the sensor component 7. At this time, the state of the sensor component 7 changes, and a signal can be sent to the control module to control the drive component 5 to stop the action, thereby maintaining the open state of the pressing plate 4 and the bottom plate 3 to facilitate the demolding of the rubber and plastic body.

[0044] In addition, there are two limiting rails 22, which are respectively fixed to the opposite sides of the two side supports 14; the limiting rail 22 is located above the guide rail 21, and the limiting rail 22 and the guide rail 21 are spaced apart, which can play a limiting role when the guide block 41 moves upward along the guide rail 21 and the pressure plate 4 flips upward, thereby reducing the possibility of the pressure plate 4 flipping back and eventually hitting the surface of the device body 1, thereby ensuring the safety of the operation of the device.

[0045] The implementation principle of a rubber and plastic molding device in the embodiment of the present application is:

[0046] In the present application, the upper mold of the mold is installed on the bottom surface of the pressing plate 4, and the lower mold of the mold is installed on the surface of the bottom plate 3. When the mold frame mechanism is located at the molding station 11, the pressing plate 4 rotates toward the bottom plate 3 under the action of its own gravity and abuts against the exhaust spring 31; when injection molding is performed, the lower pressing mechanism 13 is moved downward and forces the pressing plate 4 to move downward, so that the upper mold of the mold and the lower mold of the mold can be kept in contact with each other, so as to facilitate the injection molding of the rubber-plastic body; after molding, the lower pressing mechanism 13 is reset, and the pressing plate 4 automatically resets upward under the elastic force of the exhaust spring 31, so that the gas in the mold cavity can be easily discharged.

[0047] Then, by controlling the linear drive member 51 to move to drive the mold frame mechanism to enter the material taking station 12, the guide block 41 can abut against the guide rail 21 and move upward along the guide rail 21, so that the pressing plate 4 automatically flips away from the bottom plate 3, thereby realizing the automatic separation between the upper mold and the lower mold, which can facilitate the rapid demolding of the rubber and plastic body and reduce the labor intensity of the operators.

[0048] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
