Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of scrap recovery, and in particular to a keycap processing scrap recovery device. BACKGROUND

[0002] The keycap is processed by the process of injection molding, so that the molten raw material is injected into the mold through extrusion, and the molten raw material is dispersed into the inside of a plurality of keycap forming mold cavities after passing through the internal transmission channel of the mold.

[0003] The prior art has the following problems:

[0004] However, when the keycap injection molding mold is opened, the injection molding scrap inside the injection channel will form a connecting piece connected to multiple keycaps. At this time, if it is directly picked up, the keycaps at different positions of the connecting piece will be pulled due to different forces. If trimming is performed to pick up, it cannot be guaranteed that the force is uniform, and independent trimming of each keycap is performed, which will also cause different pulling forces on multiple keycaps. In addition, the connecting piece formed by the scrap inside the connecting channel needs to be crushed to reduce the volume before being recycled, which increases the energy consumption and process of recycling.

[0034] The surface of the base is provided with a driving stand, a traction stand, a discharging plate and a fixing stand, a moving rod is rotatably arranged between the driving stand and the traction stand, the moving seat is movably connected with the moving rod, a moving source one is installed on the side of the driving stand, and the output shaft of the moving source one is movably arranged through the driving stand and in transmission connection with the moving rod.

[0037] The beneficial effects of the present application are as follows:

[0038] By designing the injection channel composed of the branch cavity and the main cavity in a layered manner relative to the keycap molding cavity, when the injection molding residue in the internal space of the branch cavity is cleaned, the connector formed by the injection molding residue is relatively independent and separated from the keycap after molding, thereby reducing mutual interference between the two and solving the problem of being unable to be trimmed independently. In addition, during the cleaning process of the branch cavity residue, part of the residue will also be squeezed to fill the inside of the keycap molding cavity, thereby improving the molding quality of the keycap. When the residue in the injection molding transmission composed of the branch cavity and the main cavity is pushed into the inside of the recycling processing cavity, the residue is squeezed into the inside of the molding hole by the pushing block, and the molding hole refines the molding of the residue and reduces its volume, thereby completing the full recycling of the residue.

[0039] The pressure plate, upper template and lower template that control the closed state move downward synchronously. At this time, the trigger head 1 will first transfer from the initial plate 1 to the moving plate 1, and then transfer along the moving plate 1 to the inside of the maintaining plate 1, so that the trigger head 1 pushes the branch rod to approach the main cavity. When the branch rod approaches the main cavity, the branch push plate connected to the branch rod moves from the outside of the branch cavity to the inside of the branch cavity, so that the branch push plate squeezes the molten raw material at its front end into the inside of the main cavity during movement, thereby completing the cleaning of the residual material inside the branch cavity.

[0040] The pushing and squeezing of the branch push plate will shrink the internal space of the branch cavity and increase the internal pressure of the branch cavity, thereby pressurizing and pushing the excess material, so that part of the molten raw material enters the keycap molding cavity, reducing the problem of rough surface cracks caused by lack of material or lack of pressure after the keycap is molded. The pushing of the branch push plate removes the excess material inside the branch cavity, so that the keycap and the connector after the residual material molding inside the injection molding channel are separated after the final injection molding is completed, so that the key mold after the injection molding is independent of the connector after the residual material molding inside the injection molding channel, reducing the existing connector after the residual material molding inside the injection molding channel connecting multiple keycaps in series, so that the connector cannot independently separate the molded keycaps, thereby reducing the problem of damage to the keycap surface caused by different pulling forces on different keycaps when the connector after the residual material molding separates multiple keycaps.

[0041] The closed pressure plate, upper template and lower template continue to slowly descend, and the trigger head three is transferred from the inclined guide plate between the closed plate one and the open plate to the open plate, so that the push block continues to move to the outside of the recovery processing chamber under the pull of the pull-back member, so that the internal space of the recovery processing chamber is slowly released, and in this process, the trigger head two is transferred from the initial plate two along the moving plate two to the maintaining plate two, so that the space from the initial plate two to the maintaining plate two is reduced, and the main push plate moves from the outside of the main cavity to the discharge port, and when the trigger head two moves to the inside of the maintaining plate two, the remaining material inside the main cavity is pushed into the inside of the recovery processing chamber by the main push plate, thereby completing the cleaning of the branch cavity and the remaining material inside the main cavity, which is convenient for subsequent injection molding, and at this time, the trigger head three moves to the inside of the open plate, so that the space inside the recovery processing chamber blocked by the push block is released.

[0042] Continuously slow down the closed pressing plate, the upper die plate and the lower die plate, so that the trigger head one moves down the surface of the maintenance plate one, at this time the trigger head three moves along the inclined guide plate at the bottom of the open plate to the closed plate two, so that the pull-back piece is compressed, the push block is pressed back to the inside of the recycling processing cavity, the excess material cleaned from the branch cavity and the main cavity is pushed by the push block to the inside of the molding hole, so that when the trigger head three finally moves to the surface of the closed plate two, the push block contacts the upper die plate, the push block completes the extrusion of the excess material on the bottom surface of the recycling processing cavity, the excess material on the bottom surface of the recycling processing cavity is pressed into the inside of the molding hole to complete the refinement of the excess material, so that the excess material is extruded into a strip-shaped injection molding raw material, which facilitates the secondary molding of the excess material in the mold, reduces the subsequent process of breaking and reprocessing the excess material, and completes the extrusion molding of the excess material before it cools, so that the molded excess material can be used as raw material in injection molding parts with low machining precision, thereby completing the recycling of the injection excess material.

[0092] Operation process:

[0093] Injection mold preparation:

[0094] Before the screw cavity 1044 injection, by starting the mobile source one 1021, make the mobile source one 1021 drive the moving rod 1022 rotation, make the moving rod 1022 drive the moving seat 1041 in the inside of the track groove 1011 move, thereby drive the screw cavity 1044 and the pressing plate 201 close to the upper die plate 202, and finally make the pressing plate 201 extrude the upper die plate 202 close to the lower die plate 203, while the pressing plate 201 and the upper die plate 202 close to the lower die plate 203, the lower die plate 203 will also be started under the mobile source two 1061, make the mobile source two 1061 push the lower die plate 203 to the upper die plate 202 and the pressing plate 201 close to the upper die plate 202 and the pressing plate 201, and then the lower die plate 203 and the upper die plate 202 close in the inside of the trigger ring plate 204, make the lower die plate 203 and the upper die plate 202 close to form the key cap forming cavity, that is, the upper die cavity 2025 close to the convex die surface of the lower die plate 203 surface, the key cap forming cavity is formed between the two, and the corresponding branch cavity 2022 and the main cavity 2023 between the pressing plate 201 and the upper die plate 202 close to form the transmission cavity of the transmission of the molten state of the injection material;

[0095] When the lower die plate 203 and the upper die plate 202 and the pressing plate 201 close in the inside of the trigger ring plate 204, the telescopic rod 2014 is compressed to the inside of the containing cavity 2021 at this time, and at this time, under the elastic support of the elastic element one 20247 and the push of the initial plate one 20411, make the trigger head one 20242 contact with the surface of the initial plate one 20411, thereby make the branch push plate 20241 located on the outside of the branch cavity 2022 and the main cavity 2023, contact seal the outside of the branch cavity 2022;

[0096] At the same time, under the elastic support of the elastic element two 20264 and the push of the initial plate two 20421, make the trigger head two 20262 contact with the surface of the initial plate two 20421, make the main push plate 20261 located on the outside of the main cavity 2023 and the recovery element 205, make the outside of the main cavity 2023 be contact sealed by the main push plate 20261;

[0097] Meanwhile, in the elastic stretching of the pull-back 20524 and the pushing of the closing plate one 20431, the trigger head three 20522 is in contact with the surface of the closing plate one 20431, and the push block 20523 is attached to the outside of the discharge port 20231, so that the push block 20523 is in contact with the discharge port 20231, thereby completing the layered construction of the keycap forming cavity and the transmission cavity when the pressing plate 201, the upper mold plate 202, and the lower mold plate 203 are closed, and further completing the mold closing preparation before injection molding.

[0098] Formal injection molding:

[0099] The injection material is added to the lower hopper 1043, and the electromagnetic valve (not shown) at the connection between the lower hopper 1043 and the screw cavity 1044 controls the amount of injection material entering the inside of the screw cavity 1044, so that the injection material is heated by the resistance wire outside the screw cavity 1044 and is extruded into the inside of the injection port 2011 under the rotation of the screw inside the screw cavity 1044. The molten material is dispersed into the branch cavity 2022 through the main cavity 2023 and the injection port 2011, and the molten material in the branch cavity 2022 enters the keycap forming cavity formed by the closing of the upper mold plate 202 and the lower mold plate 203 through the delivery hole 20221 at the bottom of the branch cavity 2022. When the molten material is injected into the inside of the injection port 2011, the screw cavity 1044 stops injecting the molten material into the inside of the injection port 2011, and the pressure in the branch cavity 2022 and the main cavity 2023 is maintained relatively constant. At this time, the main cavity 2023 and the branch cavity 2022 have residual injection material inside;

[0100] The moving source one 1021 and the moving source two 1061 are started synchronously to control the pressing plate 201, the upper mold plate 202, and the lower mold plate 203 to move downward synchronously. At this time, the trigger head one 20242 is transferred from the initial plate one 20411 to the moving plate one 20412, and then to the inside of the maintaining plate one 20413, so that the trigger head one 20242 pushes the branch rod 2024 to move closer to the main cavity 2023 under the space reduction of the initial plate one 20411 to the maintaining plate one 20413. When the branch rod 2024 moves closer to the main cavity 2023, the branch push plate 20241 connected to the branch rod 2024 moves from the outside of the branch cavity 2022 to the inside, so that the branch push plate 20241 pushes the molten material at the front end into the inside of the main cavity 2023 during the movement, thereby completing the cleaning of the residual material in the branch cavity 2022;

[0101] And the internal space of the main cavity 2023 and the branch cavity 2022 will maintain relatively stable pressure after the injection molding is completed. Through the extrusion of the branch push plate 20241, the internal space of the branch cavity 2022 will be reduced, and the internal pressure of the branch cavity 2022 will be increased, so that the excess material is pushed and pressed, and part of the molten raw material enters the inside of the keycap forming cavity, reducing the problem of surface roughness and cracks caused by lack of material or lack of pressure after keycap forming. The excess material in the branch cavity 2022 is removed by the pushing of the branch push plate 20241, so that the connecting piece formed by the excess material in the inside of the injection channel is separated after the final injection molding, and the key mold is independent of the connecting piece formed by the excess material in the inside of the injection channel after the injection mold is opened. The existing connecting piece formed by the excess material in the inside of the injection channel is connected to multiple keycaps, so that the connecting piece cannot independently separate the formed keycaps, thereby reducing the problem that the connecting piece formed by the excess material separates multiple keycaps, and the different pulling forces on different keycaps cause damage to the surface of the keycaps.

[0102] When the branch push plate 20241 extrudes the excess material in the branch cavity 2022, the sealing plate 20243 at the bottom of the branch push plate 20241 seals the bottom of the branch cavity 2022, so that the upper die cavity 2025 at the bottom of the branch cavity 2022 is relatively independent. At the same time that the excess material in the branch cavity 2022 is cleaned, the heating element 20151 in the heating cavity 2015 is started to maintain the temperature of the molten excess material in the branch cavity 2022 and the main cavity 2023 stable, preventing it from overcooling and clumping. During the pushing process of the branch push plate 20241, the vibration source 20131 is started synchronously, so that the vibration source 20131 drives the rotating disc 20132 to rotate, the rotating disc 20132 drives the swing arm 20133 to rotate, and the swing arm 20133 pulls the pressure rod 20134 to move up and down reciprocally. Thus, the pressure rod 20134 constantly hits the transmission plate 2012 during the up-and-down reciprocating movement, so that the transmission plate 2012 transmits the vibration from top to bottom to the pressure plate 201 and the recovery piece 205, so that the molten raw material is more densely distributed in the inside of the keycap forming cavity.

[0103] When the pressure plate 201, the upper die plate 202, and the lower die plate 203 move in the closing movement, the trigger head one 20242 moves from the initial plate one 20411 to the inside of the maintenance plate one 20413, at this time the trigger head two 20262 moves on the surface of the initial plate two 20421, so that the main push plate 20261 is still located at the side of the main cavity 2023 and is stationary. At this time, the trigger head three 20522 moves along the closing plate one 20431 to the surface of the inclined guide plate 20432 between the closing plate one 20431 and the opening plate 20433, so that the pull-back piece 20524 pulls the push block 20523 outward, the internal space of the recovery processing cavity 2051 is partially released, and part of the excess material pushed from the inside of the branch cavity 2022 to the inside of the main cavity 2023 enters the inside of the recovery processing cavity 2051 to complete the expansion space pressure relief.

[0104] After the trigger head 1 20242 is transferred to the maintaining plate 1 20413, the branch push plate 20241 moves to the connection between the branch cavity 2022 and the main cavity 2023 to seal the conduction between the branch cavity 2022 and the main cavity 2023, and then the closed pressing plate 201, the upper template 202 and the lower template 203 continue to slowly descend, so that the trigger head 3 20522 is transferred from the inclined guide plate 20432 between the closing plate 1 20431 and the opening plate 20433 to the opening plate 20433, and the pushing block 20523 continues to move toward the outside of the recovery processing chamber 2051 under the pull of the pull-back member 20524, so that the internal space of the recovery processing chamber 2051 is slowly released, and in the process, the trigger head 20262 is moved from the initial plate 20 421 is transferred along the second moving plate 20422 to the second maintaining plate 20423, so that the space between the initial plate 20421 and the second maintaining plate 20423 is reduced, and the main trunk push plate 20261 moves from the outside of the main trunk cavity 2023 to the discharge port 20231. When the second trigger head 20262 moves to the inside of the second maintaining plate 20423, the residual material inside the main trunk cavity 2023 is pushed into the inside of the recovery processing cavity 2051 by the main trunk push plate 20261, thereby completing the cleaning of the residual material inside the branch cavity 2022 and the main trunk cavity 2023, which is convenient for subsequent injection molding. At this time, the third trigger head 20522 moves to the inside of the open plate 20433, so that the space blocked by the push block 20523 inside the recovery processing cavity 2051 is released.

[0105] The closed pressure plate 201, the upper mold plate 202 and the lower mold plate 203 continue to slowly descend, the trigger head one 20242 moves under the surface of the maintenance plate one 20413, the branch push plate 20241 maintains the relative sealing state of the branch cavity 2022 and the main stem cavity 2023, at this time the trigger head two 20262 moves under the surface of the maintenance plate two 20423, the main stem push plate 20261 continues to maintain inside the discharge port 20231, the sealing between the recycling processing cavity 2051 and the discharge port 20231 is completed, and at this time the trigger head three 20522 moves along the inclined guide plate 20432 at the bottom of the opening plate 20433 to the closed plate two 20434, the pull-back piece 20524 is compressed, the push block 20523 is pressed back into the recycling processing cavity 2051, the excess material cleaned from the inside of the branch cavity 2022 and the main stem cavity 2023 is pushed by the push block 20523 to the inside of the molding hole 20511, so that when the trigger head three 20522 finally moves to the surface of the closed plate two 20434, the push block 20523 contacts the upper mold plate 202, the push block 20523 completes the extrusion of the excess material at the bottom surface of the recycling processing cavity 2051, the excess material at the bottom surface of the recycling processing cavity 2051 is pressed into the inside of the molding hole 20511 to complete the refinement of the excess material, so that the excess material is extruded into a strip-shaped injection molding raw material, facilitating the secondary molding of the excess material inside the mold, reducing the subsequent process of breaking and reprocessing the excess material, and completing the extrusion molding of the excess material before it cools, so that the molded excess material can be used as raw material in injection molding parts with low machining precision, thereby completing the recycling of injection molding excess material.

[0106] Of course, the elastic force of the adjusting elastic member 20542 can be adjusted, and a more elastic supporting adjusting elastic member 20542 can be replaced, so that the adjusting elastic member 20542 initially pushes the insertion rod 20543 into the inside of the molding hole 20511, the insertion rod 20543 reduces the space of the molding hole 20511, the insertion rod 20543 reduces the space inside the molding hole 20511 to the size of a particle space, and the excess material pushed into the inside of the molding hole 20511 by the push block 20523 is molded inside the molding hole 20511 and the top end of the insertion rod 20543, and then the strip-shaped excess material is processed into a granular shape.

[0107] In summary: by the layered design of the injection molding channel composed of the branch cavity 2022 and the main cavity 2023 relative to the keycap forming cavity, the injection molding excess material in the internal space of the branch cavity 2022 is cleaned, the connecting piece after the injection molding of the excess material is relatively independently separated from the keycap after forming, the mutual interference of the two is reduced, and the problem of being unable to independently trim is solved. During the cleaning process of the excess material in the branch cavity 2022, some excess material is also extruded to fill the inside of the keycap forming cavity, improving the forming quality of the keycap. The excess material inside the injection molding transmission composed of the branch cavity 2022 and the main cavity 2023 is pushed into the inside of the recycling processing cavity 2051, the excess material is extruded by the pushing block 20523 in the molding hole 20511, the molding hole 20511 refines and reduces the volume of the excess material, thereby completing the full recycling of the excess material.
