Specific embodiments

[0027] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0028] First embodiment:

[0029] Please refer to Figures 1 to 3 , the present invention provides a foaming molding die for an automotive door panel armrest, including a base 101, a support plate 102, an upper mold 103, a rotating mechanism, a lifting mechanism, a lower mold 104, a temperature control mechanism, a mixing mechanism and a limiting mechanism. The rotating mechanism includes a rotating part 105, a rotating shaft body 106 and an upper mold frame 107. The lifting mechanism includes a lifting part 108, a telescopic rod 109 and a guide plate 110. The temperature control mechanism includes a heating layer 111, a temperature sensor 112, a control module 113 and a timing alarm 114. The mixing mechanism includes a driving part 115, a stirring rod 116 and a stirring blade 117. The limiting mechanism includes a fixing block 118, a locking module 119 and a limiting member.

[0030] In this embodiment, by pouring two kinds of solutions required for PU foaming into the lower mold 104 and mixing them evenly, and then arranging the suction cup 122 in the upper mold 103, the armrest frame 121 to be foamed and formed can be adsorbed in the upper mold 103 through the adsorption effect of the suction cup 122. After that, the upper mold 103 is flipped by the rotation mechanism, and then the lower mold 104 is lifted and lowered by the lifting mechanism, so that the upper mold 103 can be closed with the lower mold 104. At this time, a suitable temperature is provided for the solution in the lower mold 104, so that the solution in the lower mold 104 can be foamed to obtain a foam body, and finally contact the armrest frame 121 in the upper mold 103 to obtain the required automotive door panel armrest. Subsequently, the lower mold 104 is first lifted and lowered, and then the upper mold 103 is flipped, so that the automotive door panel armrest in the upper mold 103 can be exposed and finally taken out. During the entire foaming and forming process, since the armrest frame 121 and the finally obtained automotive door panel armrest are adsorbed by the suction cup 122, when taking out the automotive door panel armrest, only the adsorption force of the suction cup 122 needs to be released, which is convenient for taking out the formed automotive door panel armrest, and further ensures the quality of the formed automotive door panel armrest, solving the technical problem that in the existing foaming and forming mold during use, it is not easy to spray the release agent, resulting in inconvenience in taking out the formed product, thus reducing the quality of the product.

[0031] Among them, the number of the support plates 102 is two, and they are respectively arranged on the left and right sides of the base 101. The upper mold 103 is located between the two support plates 102. The upper mold 103 is provided with a suction cup 122. The rotation mechanism is used to rotate the upper mold 103. The lower mold 104 is connected to the base 101 through the lifting mechanism and is located below the upper mold 103. The temperature control mechanism is used to intelligently control the temperature in the lower mold 104. The mixing mechanism is used to stir and mix the solution in the lower mold 104. The limiting mechanism is used to limit and fix the upper mold 103 on the lower mold 104. The armrest frame 121 is adsorbed by the suction cup 122 to realize the limiting and fixing of the armrest frame 121 in the upper mold 103. The upper mold 103 is of a hollow structure. The number of the suction cups 122 is two, and they are respectively located on the left and right sides in the upper mold 103. The suction cup 122 is a vacuum suction cup. When it is necessary to clamp the armrest frame 121, the air in the suction cup 122 is extracted to form a negative pressure in the suction cup 122. At this time, the suction cup 122 will generate an adsorption force to adsorb the armrest frame 121. The lower mold 104 has a profiling groove, and two kinds of solutions required for PU foaming can be poured into the profiling groove of the lower mold 104 and stirred and mixed in the profiling groove of the lower mold 104.

[0032] Secondly, the rotating part 105 is arranged outside one of the support plates 102. Both ends of the rotating shaft body 106 are respectively connected to the output end of the rotating part 105 and the other support plate 102. The upper die holder 107 is sleeved outside the rotating shaft body 106 and is arranged on the upper die 103. The output end of the rotating part 105 is connected to the rotating shaft body 106 and drives the rotating shaft body 106 to rotate along its own axis, thereby driving the upper die holder 107 to rotate along the axis of the rotating shaft body 106 between the two support plates 102, and further driving the upper die holder 107 to rotate along the axis of the rotating shaft body 106 between the two support plates 102.

[0033] Thirdly, the output end of the lifting part 108 is connected to the lower die 104. The lifting part 108 is arranged on the base 101. The telescopic rod 109 is arranged between the base 101 and the lower die 104. The guide plate 110 is slidably arranged outside each support plate 102, and the guide plate 110 is arranged outside the lower die 104. The output end of the lifting part 108 is connected to the lower die 104 and drives the lower die 104 to move up and down above the base 101. At this time, the telescopic rod 109 will extend and contract. By arranging the telescopic rod 109, the support stability of the lower die 104 can be improved. The guide plate 110 has a slot, and the support plate 102 penetrates through the slot of the guide plate 110. When the lower die 104 moves up and down above the base 101, the guide plate 110 can slide up and down outside the support plate 102 to limit the moving direction of the lower die 104, so that the lower die 104 can only move up and down above the base 101.

[0034] At the same time, the heating layer 111 is arranged in the lower mold 104, the temperature sensor 112 is arranged at the inner bottom of the lower mold 104, the control module 113 is electrically connected to the heating layer 111 and the temperature sensor 112 respectively, and is arranged on the base 101, the timing alarm 114 is electrically connected to the control module 113 and is arranged on the base 101, the temperature sensor 112 can detect the temperature in the lower mold 104 in real time, and transmit the detection result to the control module 113, so that the control module 113 can control the start and stop of the heating layer 111 according to the detection result, so as to heat or stop the solution in the lower mold 104 to ensure that the temperature of the lower mold 104 can always be maintained at 40-50°C. During this process, the timing alarm 114 can time and send an alarm signal to the control module 113 after reaching the preset time, so that the control module 113 can stop the operation of the heating layer 111.

[0035] In addition, the driving part 115 is arranged outside the lower mold 104, the stirring rod 116 is connected to the output end of the driving part 115, and passes through the lower mold 104 and the heating layer 111 respectively, and a plurality of stirring blades 117 are staggeredly arranged outside the stirring rod 116. The output end of the driving part 115 is connected to the stirring rod 116, and drives the stirring rod 116 to rotate along its own axis, thereby driving the stirring blade 117 to rotate along the axis of the stirring rod 116 in the profiling groove of the lower mold 104, thereby achieving stirring and mixing of the solution in the profiling groove of the lower mold 104.

[0036] Finally, the number of the fixing blocks 118 is two, and they are respectively arranged on the front and rear sides outside the lower die 104. The locking module 119 is detachably arranged in each fixing block 118. The limiting member is used to limit and fix the locking module 119 in the fixing block 118. The limiting member is a limiting bolt 120. The limiting bolt 120 is detachably connected to the fixing block 118 and the locking module 119 respectively. The limiting bolt 120 penetrates through the fixing block 118 and the locking module 119 respectively. The fixing block 118 has an engaging groove, and the locking module 119 has a protrusion. The protrusion of the locking module 119 is matched with the engaging groove of the fixing block 118 and can be inserted into the engaging groove of the fixing block 118. Both the locking module 119 and the fixing block 118 have threaded holes. The limiting bolt 120 has an external thread. The external thread of the limiting bolt 120 is matched with the threaded holes of the locking module 119 and the fixing block 118 and can move along the thread track in the threaded holes of the locking module 119 and the fixing block 118, so that the limiting bolt 120 can be tightened in the threaded holes of the locking module 119 and the fixing block 118, so that the protrusion of the locking module 119 can be limited and fixed in the engaging groove of the fixing block 118, and further the upper die 103 can be limited and fixed on the lower die 104.

[0037] When using the foaming mold for the armrest of an automobile door panel of this embodiment, place the armrest skeleton 121 in the upper die 103, and make both sides of the armrest skeleton 121 located at the positions of the two suction cups 122 in the upper die 103 respectively. Extract the air in the suction cups 122 to form a negative pressure in the suction cups 122. At this time, the suction cups 122 will generate an adsorption force to adsorb the armrest skeleton 121, realizing the clamping and fixing of the armrest skeleton 121 to ensure the stability of the armrest skeleton 121.

[0038] Inject the two solutions required for PU foaming into the profiling groove of the lower die 104, and start the driving part 115, so that the power output by the output end of the driving part 115 drives the stirring rod 116 to rotate along its own axis, thereby driving the stirring blades 117 to rotate along the axis of the stirring rod 116 in the profiling groove of the lower die 104, realizing the stirring and mixing of the solutions in the profiling groove of the lower die 104 to ensure that the two solutions can be mixed evenly.

[0039] After that, start the rotating part 105 so that the power output from the output end of the rotating part 105 drives the rotating shaft body 106 to rotate along its own axis, thereby driving the upper die holder 107 to rotate along the axis of the rotating shaft body 106 between the two support plates 102, and further driving the upper die holder 107 to rotate along the axis of the rotating shaft body 106 between the two support plates 102, causing the upper die holder 107 to flip downward around the rotating shaft body 106, driving the upper die 103 to flip downward. When the lower die 104 flips 180 degrees, then start the lifting part 108 so that the power output from the output end of the lifting part 108 drives the lower die 104 to move up and down above the base 101. At this time, the guide plate 110 can slide up and down outside the support plate 102 to limit the moving direction of the lower die 104, enabling the lower die 104 to only move up and down above the base 101. Move the lower die 104 upward until the lower die 104 contacts the upper die 103, realizing the upper die 103 closing on the lower die 104. At this time, the protrusion of the lock module 119 will insert into the engagement groove of the fixed block 118, and then screw the limit bolt 120 into the threaded holes of the lock module 119 and the fixed block 118, and make the limit bolt 120 move along the thread track in the threaded holes of the lock module 119 and the fixed block 118, so that the limit bolt 120 can be screwed tightly in the threaded holes of the lock module 119 and the fixed block 118, thereby enabling the protrusion of the lock module 119 to be limited and fixed in the engagement groove of the fixed block 118, and further enabling the upper die 103 to be limited and fixed on the lower die 104.

[0040] Start the timing alarm 114 to make the timing alarm 114 start timing. At the same time, start the control module 113 and the temperature sensor 112, so that the temperature sensor 112 can detect the temperature inside the lower die 104 in real time and transmit the detection result to the control module 113, enabling the control module 113 to control the start and stop of the heating layer 111 according to this detection result, thereby realizing heating or stopping heating of the solution inside the lower die 104 to ensure that the temperature of the lower die 104 can always be maintained at 40 - 50 °C, and further enabling the two solutions mixed evenly inside the lower die 104 to gradually foam and finally obtain a foam body.

[0041] During the time when the upper die 103 is closed on the lower die 104, the armrest skeleton 121 inside the upper die 103 will gradually contact the foam body inside the lower die 104 and start bonding and closing the mold. As the foam body cures, the armrest skeleton 121 gradually forms into an armrest for a car door panel.

[0042] After reaching the preset time, the timing alarm 114 will emit an alarm sound and send an alarm signal to the control module 113, so that the control module 113 can stop the operation of the heating layer 111. At this time, the limit bolt 120 is gradually screwed out from the threaded holes of the lock module 119 and the fixing block 118, so that the fixed state between the lock module 119 and the fixing block 118 is released, and thus the fixed state of the upper mold 103 on the lower mold 104 is released. After that, the lower mold 104 is moved downward, and then the upper mold 103 is turned upward, so that the automotive door panel armrest obtained in the upper mold 103 can be exposed.

[0043] Air is injected into the suction cup 122 to release the negative pressure state in the suction cup 122, so that the adsorption force of the suction cup 122 on the automotive door panel armrest is released. After that, the obtained automotive door panel armrest is taken out from the upper mold 103, and then the automotive door panel armrest is trimmed and inspected to ensure that the automotive door panel armrest meets the quality requirements.

[0044] Second Embodiment:

[0045] Based on the first embodiment, please refer to Figure 4 , the present invention also provides a foaming molding method for an automotive door panel armrest, including the following steps:

[0046] S101. Place the skeleton. The armrest skeleton 121 is placed in the upper mold 103 and adsorbed by the suction cup 122 to ensure the stability of the armrest skeleton 121.

[0047] Specifically, the armrest skeleton 121 is placed in the upper mold 103, and both sides of the armrest skeleton 121 are respectively located at the positions of the two suction cups 122 in the upper mold 103. The air in the suction cup 122 is extracted to form a negative pressure in the suction cup 122. At this time, the suction cup 122 will generate an adsorption force to adsorb the armrest skeleton 121, realizing the clamping and fixing of the armrest skeleton 121 to ensure the stability of the armrest skeleton 121.

[0048] S102. Mix the solutions. The two solutions required for PU foaming are injected into the profiling groove of the lower mold 104 for mixing, and ensure uniform mixing.

[0049] Specifically, inject the two solutions required for PU foaming into the profiling groove of the lower mold 104, and start the driving part 115, so that the power output by the output end of the driving part 115 drives the stirring rod 116 to rotate along its own axis, thereby driving the stirring blade 117 to rotate along the axis of the stirring rod 116 in the profiling groove of the lower mold 104, realizing the stirring and mixing of the solutions in the profiling groove of the lower mold 104 to ensure that the two solutions can be mixed evenly.

[0050] S103. Close the mold. Flip the upper mold frame 107 downward around the rotating shaft body 106, drive the upper mold 103 to flip downward, close it on the lower mold 104, and lock the lock module 119 in the connection groove.

[0051] Specifically, after that, start the rotating part 105, so that the power output by the output end of the rotating part 105 drives the rotating shaft body 106 to rotate along its own axis, thereby driving the upper mold frame 107 to rotate along the axis of the rotating shaft body 106 between the two support plates 102, and further driving the upper mold frame 107 to rotate along the axis of the rotating shaft body 106 between the two support plates 102, so that the upper mold frame 107 flips downward around the rotating shaft body 106, driving the upper mold 103 to flip downward. When the lower mold 104 flips 180 degrees, then start the lifting part 108, so that the power output by the output end of the lifting part 108 drives the lower mold 104 to move up and down above the base 101. At this time, the guide plate 110 can slide up and down outside the support plate 102 to limit the moving direction of the lower mold 104, so that the lower mold 104 can only move up and down above the base 101. Move the lower mold 104 upward until the lower mold 104 contacts the upper mold 103, realizing the upper mold 103 closing on the lower mold 104. At this time, the protrusion of the lock module 119 will insert into the connection groove of the fixed block 118, and then screw the limit bolt 120 into the threaded holes of the lock module 119 and the fixed block 118, and make the limit bolt 120 move along the thread track in the threaded holes of the lock module 119 and the fixed block 118, so that the limit bolt 120 can be tightened in the threaded holes of the lock module 119 and the fixed block 118, thereby enabling the protrusion of the lock module 119 to be limited and fixed in the connection groove of the fixed block 118, and further enabling the upper mold 103 to be limited and fixed on the lower mold 104.

[0052] S104. Temperature control. Start the timing alarm 114 and control the temperature of the lower mold 104 to keep the temperature of the lower mold 104 always at 40 - 50 °C, and gradually foam the two evenly mixed solutions to obtain a foam body.

[0053] Specifically, start the timing alarm 114 to make it start timing. At the same time, start the control module 113 and the temperature sensor 112, so that the temperature sensor 112 can detect the temperature inside the lower mold 104 in real time and transmit the detection result to the control module 113, enabling the control module 113 to control the start and stop of the heating layer 111 according to this detection result, thereby realizing heating or stopping heating of the solution inside the lower mold 104 to ensure that the temperature of the lower mold 104 can always be maintained at 40 - 50 °C, and further enabling the two solutions mixed evenly inside the lower mold 104 to gradually foam and finally obtain a foam body.

[0054] S105. Curing: During the mold closing time, make the armrest skeleton 121 contact the foam body and start bonding and closing the mold. As the foam body cures, the armrest gradually takes shape.

[0055] Specifically, during the time when the upper mold 103 closes on the lower mold 104, the armrest skeleton 121 inside the upper mold 103 will gradually contact the foam body inside the lower mold 104 and start bonding and closing the mold. As the foam body cures, the armrest skeleton 121 gradually takes shape into an armrest for a car door panel.

[0056] S106. Mold opening: After reaching the mold closing time, the timing alarm 114 will emit an alarm sound. At this time, unlock the lock module 119 and flip the upper mold 103 upward to obtain an armrest for a car door panel.

[0057] Specifically, after reaching the preset time, the timing alarm 114 will emit an alarm sound and send an alarm signal to the control module 113, so that the control module 113 can stop the operation of the heating layer 111. At this time, gradually screw out the limit bolt 120 from the threaded holes of the lock module 119 and the fixed block 118, so that the fixed state between the lock module 119 and the fixed block 118 is released, thereby releasing the fixed state of the upper mold 103 on the lower mold 104. Then, lower the lower mold 104 and flip the upper mold 103 upward, so that the armrest for a car door panel obtained inside the upper mold 103 can be exposed.

[0058] S107. Follow - up processing: Take out the obtained armrest for a car door panel, and then trim and inspect the armrest for a car door panel to ensure that the armrest for a car door panel meets the quality requirements.

[0059] Specifically, air is injected into the suction cup 122 to relieve the negative pressure state inside the suction cup 122, thereby relieving the adsorption force of the suction cup 122 on the armrest of the car door panel. After that, the obtained armrest of the car door panel is taken out from the upper mold 103, and then the armrest of the car door panel is trimmed and inspected to ensure that it meets the quality requirements.
