Description

Technical Field

[0001] The invention relates to the technical field of waste material recovery, and in particular to a device for recovering waste material from key cap processing. Background Art

[0002] The keycaps are processed by an injection molding process, whereby molten raw materials are injected into a mold through an extrusion device, and the molten raw materials pass through an internal transmission channel of the mold and are dispersed into multiple keycap molding cavities for internal molding.

[0003] The prior art has the following problems: However, after the keycaps are injection molded, the injection molding residue inside the injection molding channel will form a connector to connect multiple keycaps. If you pick it up directly at this time, the keycaps at different positions of the connector will be pulled due to different forces. If you trim them and take them down, it is impossible to ensure uniform force. Each keycap needs to be trimmed and removed independently, and different pulling forces will be generated on the multiple keycaps in the process. In addition, the connector formed by the residue inside the connecting channel needs to be crushed to reduce the volume before it can be recycled, which leads to additional energy consumption and process for recycling.

[0015] Beneficial effects of the present invention: 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 can be relatively separated from the keycap after molding, thereby reducing mutual interference between the two and solving the problem of being unable to trim independently. In addition, during the cleaning process of the branch cavity residue, part of the residue will be squeezed and filled into 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 recycling processing cavity, the residue is squeezed into the molding hole by the pushing block, so that the molding hole refines the molding of the residue and reduces its volume, thereby completing the full recycling of the residue.

[0016] The pressing plate, the upper template and the 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 it, so that the branch push plate squeezes the molten raw material at its front end into the inside of the main cavity during the movement, thereby completing the cleaning of the residual material inside the branch cavity.

[0017] 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, allowing part of the molten raw material to enter the keycap molding cavity, reducing the problem of rough surface cracks due to 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 formed by the excess material inside the injection channel after the final injection molding are separated, so that the key mold after injection molding is independent of the connector formed by the excess material inside the injection channel, reducing the existing connector formed by the excess material inside the injection channel to connect 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 formed by the excess material separates multiple keycaps.

[0018] The closed pressure plate, upper template and lower template continue to slowly descend, so that the trigger head three is transferred from the inclined guide plate between the closed plate one and the open plate to the open plate, and the push-close 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 main push plate moves from the outside of the main cavity to the discharge port under the push of the space shrinking from the initial plate two to the maintaining plate two, 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 blocked by the push-close block inside the recovery processing chamber is released.

[0019] Then the closed pressing plate, the upper template and the lower template continue to slowly descend, so that the trigger head one moves and descends on the surface of the maintaining plate one. At this time, the trigger head three moves toward the closed plate two along the inclined guide plate at the bottom of the open plate, so that the pull-back piece is compressed, and the push-close block is pressed back into the recovery processing chamber, so that the residual material cleaned from the branch chamber and the main chamber is pushed back into the molding hole by the push-close block. When the trigger head three finally moves to the surface of the closed plate two, the push-close block contacts the upper template, so that the push-close block completes the extrusion of the residual material on the bottom of the recovery processing chamber, and the residual material on the bottom of the recovery processing chamber is pressed into the molding hole to complete the refinement of the residual material, so that the residual material is extruded into strip-shaped injection molding raw materials, which is convenient for secondary molding of the residual material inside the mold, reduces the subsequent process of crushing and reprocessing of the residual material, and completes the extrusion molding of the residual material before it cools down, so that the residual material after molding can be used as raw material in injection molding parts with low processing precision, thereby completing the recovery of injection molding residual material.

[0031] like Figure 1-5 As shown, the trigger ring plate 204 is composed of two branch trigger plates 2041 and a main trigger plate 2042 and a recovery trigger plate 2043 which are fixedly connected by the branch trigger plates 2041 through connecting plates 2044; The branch trigger plate 2041 is integrated by an initial plate 20411, a moving plate 20412 and a maintaining plate 20413 which are arranged in sequence from top to bottom. The branch trigger plate 2041 is movably connected to a trigger head 20242 on the opposite side of the upper template 202. The main trigger plate 2042 is integrated by an initial plate 20421, a moving plate 20422 and a maintaining plate 20423 which are arranged in sequence from top to bottom. The main trigger plate 2042 is movably connected to the opposite surface of the upper template 202 by a trigger head 20262.

[0032] like Figure 1-5 As shown, the two branch trigger plates 2041 are symmetrical about the midline of the upper template 202; The distance between the initial plate 20411 and the upper template 202 is greater than the distance between the maintaining plate 20413 and the upper template 202, and the moving plate 20412 is tiltedly disposed between the initial plate 20411 and the maintaining plate 20413; The distance between the second initial plate 20421 and the upper template 202 is greater than the distance between the second maintaining plate 20423 and the upper template 202, and the second moving plate 20422 is tiltedly disposed between the second initial plate 20421 and the second maintaining plate 20423; The distance between the closed plate 1 20431 and the closed plate 20434 and the upper template 202 is the same, the distance between the open plate 20433 and the upper template 202 is greater than the distance between the closed plate 1 20431 and the closed plate 20434 and the upper template 202, and the side of the open plate 20433 opposite to the upper template 202 is fixedly connected to the top surface of the base 101.

[0033] It should be noted that the injection molding drive component 1042 and the moving source 1021 are preferably three-phase asynchronous reduction motors, the moving source 2 1061 is preferably an oil cylinder or an electric telescopic cylinder and is controlled by a unified PLC and encoder and powered by an external energy source, the moving rod 1022 is a ball screw, and the moving seat 1041 is preferably connected to the moving rod 1022 through a ball screw nut seat.

[0034] Operation process: Injection mold preparation: Before the screw cavity 1044 is injected, the moving source 1021 is started to drive the moving rod 1022 to rotate, so that the moving rod 1022 drives the moving seat 1041 to move inside the rail groove 1011 during the rotation, thereby driving the screw cavity 1044 and the pressing plate 201 to approach the upper mold plate 202, and finally the pressing plate 201 squeezes the upper mold plate 202 to approach the lower mold plate 203. When the pressing plate 201 and the upper mold plate 202 approach the lower mold plate 203, the lower mold plate 203 will also be moved by the activation of the moving source 2 1061. The lower template 203 is pushed toward the upper template 202 and the pressing plate 201 by the push rod 1062, and then the lower template 203, the upper template 202 and the pressing plate 201 that are close to each other are closed inside the trigger ring plate 204, so that the lower template 203 and the upper template 202 are closed to form a keycap molding cavity, that is, the upper mold cavity 2025 is closed to the convex die head surface on the surface of the lower template 203, and a keycap molding 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 template 202 are closed to form a transmission cavity for transmitting the molten injection plastic; When the lower template 203, the upper template 202 and the pressing plate 201 are closed inside the trigger ring plate 204, the telescopic rod 2014 is compressed into the accommodating cavity 2021, and under the elastic support of the elastic member 20247 and the push of the initial plate 20411, the trigger head 20242 contacts the surface of the initial plate 20411, so that the branch push plate 20241 is located on the outer side of the branch cavity 2022 opposite to the main cavity 2023, and the outer side of the branch cavity 2022 is contacted and sealed; At the same time, under the elastic support of the second elastic member 20264 and the push of the second initial plate 20421, the second trigger head 20262 contacts the surface of the second initial plate 20421, so that the main trunk push plate 20261 is located on the outer side of the main trunk cavity 2023 opposite to the recovery member 205, so that the outer side of the main trunk cavity 2023 is sealed by the contact of the main trunk push plate 20261; At the same time, during the elastic stretching of the pull-back member 20524 and the pushing of the closing plate 20431, the trigger head 20522 contacts the surface of the closing plate 20431, and the pushing block 20523 fits to the outer side of the discharge port 20231, so that the pushing block 20523 contacts and seals the discharge port 20231, thereby completing the layered construction of the keycap molding cavity and the transmission cavity when the pressure plate 201, the upper template 202 and the lower template 203 are closed, thereby completing the mold closing preparation before injection molding.

[0035] Formal injection molding: The injection molding 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 chamber 1044 controls the injection molding material to enter the screw chamber 1044 quantitatively, so that the injection molding material is heated by the resistance wire outside the screw chamber 1044 and the material is extruded into the injection port 2011 under the rotation of the screw inside the screw chamber 1044. The heated molten material passes through the injection port 2011 and the trunk chamber 2023 to be dispersed into the branch chamber 2022, so that the material enters the branch chamber 2023. The molten raw material in the branch cavity 2022 enters the keycap molding cavity formed by 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 a certain amount of molten raw material is injected into the injection port 2011, the screw cavity 1044 stops injecting the molten raw material into the injection port 2011, so that the pressure in the branch cavity 2022 and the main cavity 2023 is kept relatively constant. At this time, there is residual injection material in the main cavity 2023 and the branch cavity 2022. The moving source 1021 and the moving source 2 1061 are started synchronously, so that the pressing plate 201, the upper template 202 and the lower template 203 in the closed state are controlled by the two to move downward synchronously. At this time, the trigger head 1 20242 will first be transferred from the initial plate 1 20411 to the moving plate 1 20412, and then transferred to the inside of the maintaining plate 1 20413 along the moving plate 1 20412, so that the trigger head 1 20242 pushes the branch rod 2024 to approach the main trunk cavity 2023 under the push of the space reduction from the initial plate 1 20411 to the maintaining plate 1 20413. When the branch rod 2024 approaches the main trunk 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 thereof, so that the branch push plate 20241 squeezes the molten raw material at its front end into the inside of the main trunk cavity 2023 during the movement, thereby completing the cleaning of the residual material inside the branch cavity 2022; After the injection molding is completed, the internal pressure of the main cavity 2023 and the branch cavity 2022 will remain relatively stable. The pushing and squeezing of the branch push plate 20241 will shrink the internal space of the branch cavity 2022, increase the internal pressure of the branch cavity 2022, and push the excess material to make the molten raw material partly enter the keycap molding cavity, thereby 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 20241 removes the excess material inside the branch cavity 2022, so that the keycap and the connector after the residual material inside the injection channel are separated after the final injection molding, so that the key mold after the injection molding is independent of the connector after the residual material inside the injection channel is molded, reducing the existing connector after the residual material inside the injection channel is molded to connect 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 is molded separates multiple keycaps. When the branch push plate 20241 squeezes out the residual material inside the branch cavity 2022, the sealing plate 20243 at the bottom of the branch push plate 20241 will seal the bottom of the branch cavity 2022, so that the upper mold cavity 2025 at the bottom of the branch cavity 2022 is relatively independent, and while the residual material in the branch cavity 2022 is being cleaned, the heating element 20151 inside the heating cavity 2015 is started to maintain the temperature of the molten residual material inside the branch cavity 2022 and the main cavity 2023 stable to prevent it from being overcooled and agglomerated, and the branch push plate 2024 1, synchronously start the vibration source 20131, so that the vibration source 20131 drives the rotating disk 20132 to rotate, so that the rotating disk 20132 drives the swing arm 20133 to rotate, so that the swing arm 20133 pulls the pressing rod 20134 to reciprocate up and down, so that the pressing rod 20134 continuously hits the transfer plate 2012 during the reciprocating motion, so that the transfer plate 2012 transfers the vibration from top to bottom to the pressing plate 201 and the recovery member 205, so that the molten raw material is more densely distributed inside the keycap molding cavity; When the pressing plate 201, the upper template 202 and the lower template 203 are in the process of closing and moving, the trigger head 1 20242 finally moves from the initial plate 1 20411 to the inside of the maintaining plate 1 20413, and at this time, the trigger head 20262 moves on the surface of the initial plate 20421, so that the main push plate 20261 is still located at the side of the main cavity 2023 and is stationary, and at this time, the trigger head 3 20522 is transferred along the closing plate 1 20431 to the surface of the inclined guide plate 20432 between the closing plate 1 20431 and the opening plate 20433, so that the pull-back member 20524 pulls the push block 20523 outward, so that the internal space of the recovery processing cavity 2051 is partially released, so that the residual material pushed from 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 of the space pressure relief; 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 push block 20523 continues to move to 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 this process, the trigger head 20262 is moved from the initial plate 20431 to the opening plate 20433. 421 is transferred along the moving plate 20422 to the maintaining plate 20423, so that the space from the initial plate 20421 to the maintaining plate 20423 is reduced, and the main push plate 20261 moves from the outside of the main cavity 2023 to the discharge port 20231, and when the trigger head 20262 moves to the inside of the maintaining plate 20423, the residual material inside the main cavity 2023 is pushed into the inside of the recovery processing cavity 2051 by the main push plate 20261, thereby completing the cleaning of the residual material inside the branch cavity 2022 and the main cavity 2023, which is convenient for subsequent injection molding, and at this time, the trigger head 3 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; Then, the closed pressing plate 201, the upper template 202 and the lower template 203 continue to slowly descend, so that the trigger head 1 20242 moves down on the surface of the maintaining plate 1 20413, so that the branch push plate 20241 maintains the relative sealing state of the branch cavity 2022 and the main cavity 2023. At this time, the trigger head 20262 moves downward on the surface of the maintaining plate 20423, so that the main push plate 20261 continues to maintain the inside of the discharge port 20231, completing the sealing between the recovery processing cavity 2051 and the discharge port 20231. At this time, the trigger head 3 20522 moves along the inclined guide plate 20432 at the bottom of the open plate 20433 toward the closed plate 20434, so that the pull-back member 20524 is compressed, so that the push block 20523 back-presses the inside of the recovery processing cavity 2051, so that the cleaning from the branch cavity 2 022 and the residual material inside the main cavity 2023 are pushed back toward the interior of the molding hole 20511 by the pushing block 20523, so that when the trigger head three 20522 finally moves to the surface of the closing plate two 20434, the pushing block 20523 contacts the upper template 202, so that the pushing block 20523 completes the extrusion of the residual material on the bottom surface of the recovery processing cavity 2051, and the residual material on the bottom surface of the recovery processing cavity 2051 is pressed into the interior of the molding hole 20511 to complete the refinement of the residual material, so that the residual material is extruded to form strip-shaped injection molding raw materials, which is convenient for secondary molding of the residual material inside the mold, reducing the subsequent process of crushing and reprocessing of the residual material, and completing the extrusion molding of the residual material before it cools down, so that the residual material after molding can be used as raw material in injection molded parts with low processing precision, thereby completing the recycling of injection molding residual material.

[0036] Of course, the elastic force of the adjusting elastic member 20542 can also be adjusted, and the adjusting elastic member 20542 with more elastic support can be replaced, so that the adjusting elastic member 20542 initially pushes the insert rod 20543 into the interior of the shaping hole 20511, so that the insert rod 20543 reduces the space of the shaping hole 20511, and the insert rod 20543 reduces the space inside the shaping hole 20511 to the size of a particle space, so that the pushed block 20523 is pushed into the shaping hole 20511, and the remaining material is formed inside the shaping hole 20511 and on the top of the insert rod 20543, thereby making the strip-shaped remaining material be processed into particles.

[0037] In summary: by designing the injection channel composed of the branch cavity 2022 and the main cavity 2023 in a layered manner relative to the keycap molding cavity, when the injection molding residue in the internal space of the branch cavity 2022 is cleaned, the connector formed by the injection molding residue can be relatively 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 2022 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 formed by the branch cavity 2022 and the main cavity 2023 is pushed into the recycling processing cavity 2051, the residue is squeezed into the molding hole 20511 by the pushing block 20523, and the molding hole 20511 refines the molding of the residue and reduces its volume, thereby completing the full recycling of the residue.
