Description

Technical Field

[0001] The present invention belongs to the technical field of injection molding equipment, and in particular relates to a plastic shell injection molding device and a preparation method thereof. Background Art

[0002] Currently, the shells of items such as telephones and fax machines are generally plastic shells. The main process of plastic shell injection molding includes mixing raw materials, injecting the mixed raw materials into the mold, maintaining pressure and cooling the mixed raw materials, and demolding. The process of each step will affect the molding effect.

[0003] Typically, the injection molding of plastic housings is performed by an injection molding machine. After demolding, the housings exit the molding machine through the discharge port. When a batch of plastic housings is produced, the demolded housings must be quickly removed to prevent them from impacting subsequent housings leaving the molding machine. However, as they fall from the molding machine, the housings are prone to collision with the ground or other supporting structures. Furthermore, the housings can rub against the ground or other supporting structures when being pushed away, potentially causing damage. Furthermore, the removed housings can scatter across various areas, potentially slowing down subsequent packaging. Summary of the Invention

[0055] Please refer to Figures 1 to 10 , a plastic shell injection molding device and a preparation method thereof, comprising:

[0056] Injection molding unit 1, used to complete the injection molding operation of the plastic shell;

[0057] The adjusting portion 2 is provided at the bottom of the injection molding portion 1 and is used to support the injection molding portion 1 and adjust the distance between the discharge port of the injection molding portion 1 and the ground;

[0058] The loading portion 3 has an inner cavity for loading the injection-molded plastic shell;

[0059] The adjusting portion 2 is provided with a first through-hole, a second through-hole, and a third through-hole 35. The first through-hole is vertically provided in the adjusting portion 2 and communicates with the second through-hole 34. The second through-hole 34 is horizontally provided in the adjusting portion 2 and communicates with the third through-hole 35. The third through-hole 35 is horizontally provided in the adjusting portion 2.

[0060] The loading portion 3 has a loading state. When the loading portion 3 is in the loading state, it is placed in the second through-hole 34. When the loading portion 3 is in the loading state, a fourth through-hole 5 is defined in the side wall of the loading portion 3 near the third through-hole 35. A first groove is defined in the bottom wall of the loading portion 3, one end of which is connected to the fourth through-hole 5. A first rotating member is rotatably connected to the bottom end of the fourth through-hole 5. The first rotating member is connected to the first connecting member 11 and the second connecting member 12. A first elastic member 24 is connected between the first connecting member 11 and the bottom wall of the first groove. The first elastic member 24 can push the first connecting member 11 to place the second connecting member 12 outside the inner cavity of the loading portion 3.

[0061] A first limiting member 36 corresponding to the second connecting member 12 is detachably mounted on the wall of the third through hole 35 .

[0062] The injection molding part 1 can be set as an injection molding machine for completing the injection molding operation of the plastic shell, and the injection molding part 1 is supported by the adjustment part 2, which can be set as a support table. By selecting the adjustment part 2 of different heights, the distance between the discharge port of the injection molding part 1 and the ground can be adjusted.

[0063] The injection-molded plastic shell is received by the loading portion 3 to facilitate packaging and transfer of the plastic shell. In order to prevent the area where the loading portion 3 is located from deviating from the predetermined receiving area when in the loading state, the first limiting member 36 can limit the second connecting member 12. When the two are in contact, the loading portion 3 is in the predetermined receiving area, and the first elastic member 24 can push the first connecting member 11 to place the second connecting member 12 outside the inner cavity of the loading portion 3. Therefore, the position of the second connecting member 12 does not need to be adjusted separately.

[0064] By setting the loading part 3, the plastic shell can automatically fall into the loading part 3 after leaving the discharge port of the injection molding part 1, avoiding the additional steps of taking out the plastic shell and packaging the plastic shells separately in sequence.

[0065] The first elastic member 24 can be configured as a spring. Through the configuration of the first elastic member 24, the first elastic member 24 can automatically and indirectly push the second connecting member 12 to place it outside the inner cavity of the loading portion 3, and at the same time gradually slow down the falling speed of the plastic shell, thereby preventing the plastic shell from being damaged in the process of automatically falling into the loading portion 3; and in the process of the plastic shell squeezing the first elastic member 24, the first elastic member 24 can indirectly pull the second connecting member 12, so that the first limiting member 36 cannot indirectly limit the loading portion 3, and at the same time, it can prompt the second connecting member 12 to block the fourth through-hole 5, thereby keeping the loading portion 3 closed in the horizontal direction.

[0066] It should be noted that the plastic shell can gradually enter the first groove by the falling movement of the first elastic member 24 and the first connecting member 11, thereby preventing the first elastic member 24 and the first connecting member 11 from forming a protruding structure at the bottom of the inner cavity of the loading part 3, thereby causing the plastic shell to be easily tilted.

[0067] In some embodiments, a blocking assembly is further included, comprising a first support member 13 detachably mounted on the outer side of the side wall of the loading portion 3 , the first support member 13 having a second groove opening toward the side wall of the loading portion 3 , and a fifth through-hole 14 communicating with the second groove being formed on the side wall of the loading portion 3 ;

[0068] The blocking assembly further includes a plurality of second rotating members 31 placed in the second groove and distributed in parallel along the horizontal direction. Two adjacent second rotating members 31 are rotationally connected, and one end of the second rotating member 31 close to the bottom wall of the second groove is connected to the bottom wall of the second groove.

[0069] It should be noted that the "detachable installation" and "detachable connection" in the present invention can adopt existing threaded connection, bonding and other methods, and are not specifically limited here.

[0070] By providing the blocking assembly, after the plastic shell falls into the loading portion 3 , the second rotating member 31 can block the inner cavity opening of the loading portion 3 , thereby avoiding the need for additional manual packaging steps.

[0071] It should be emphasized that the size of the loading portion 3 and the position of the blocking component can be adjusted according to the object itself. For example, the position of the blocking component can be adjusted according to the height of the plastic shell to avoid a large space between the plastic shell and the second rotating member 31, which may cause the two to collide repeatedly. In addition, the first elastic member 24 and the first connecting member 11 mentioned above can form a protruding structure at the bottom of the inner cavity of the loading portion 3 without providing the first groove. This method can easily cause the plastic shell to tilt, thereby causing the second rotating member 31 to collide with the plastic shell during the blocking process.

[0072] In some embodiments, a third groove 18 is formed on the side wall of the loading portion 3 , with two ends of the third groove 18 facing toward and away from the fifth through-hole 14 , and the third groove 18 is connected to the fifth through-hole 14 ;

[0073] The second rotating member 31 away from the bottom wall of the second groove is connected to the second elastic member 19. One end of the second elastic member 19 is connected to the groove wall of the third groove 18 away from the fifth through hole 14.

[0074] A fourth groove 20 is formed on the side wall of the loading portion 3 where the fifth through-hole 14 is formed, the fourth groove 20 being connected to the fifth through-hole 14 and having an opening facing away from the second groove. A fifth groove is formed on the bottom wall of the loading portion 3, and the ends of the fifth groove are respectively connected to the fourth groove 20 and the first groove.

[0075] The first telescopic member 25 is connected to the wall of the fourth groove 20 , the second telescopic member 26 is connected to the wall of the first groove, and a first traction member 27 is connected between the telescopic ends of the first telescopic member 25 and the second telescopic member 26 .

[0076] When the blocking assembly performs the blocking function, on the one hand, the second rotating member 31 needs to be manually pulled; on the other hand, when there are a large number of second rotating members 31 , it is difficult to splice them in the horizontal direction.

[0077] The second elastic member 19 can be configured as a traction spring. Due to the configuration of the second elastic member 19, the second rotating member 31 can be automatically pulled by the second elastic member 19. Under the external force of the second elastic member 19, multiple second rotating members 31 can be spliced ​​horizontally, thereby reducing manual operation and maintaining the stability of the second rotating members 31. Furthermore, in this case, a plurality of second rotating members 31 can be provided and stacked horizontally within the second groove to reduce the area occupied by the first support member 13.

[0078] Initially, the second rotating member 31 is limited in the second groove by the first telescopic member 25. When the plastic shell causes the first elastic member 24 and the first connecting member 11 to gradually enter the first groove through the falling movement, the first elastic member 24 and the first connecting member 11 can squeeze the second telescopic member 26 to shrink it. At the same time, the second telescopic member 26 pulls the first telescopic member 25 to shrink through the first traction member 27, so as to release the limitation of the first telescopic member 25 on the second rotating member 31, thereby realizing the automatic sealing of the loading part 3 by the blocking assembly.

[0079] It should be noted that the first traction member 27 can be set as a traction line; the first telescopic member 25 and the second telescopic member 26 can be set as existing telescopic rods, or can be set as a combination structure of a hollow column, a sliding rod, and a spring. When set to the latter, the hollow column is connected to the inner wall of the loading part 3, the sliding rod is slidably connected to the inner wall of the hollow column, one end of the spring is connected to the inner wall of the hollow column, and the other end is connected to the sliding rod.

[0080] In some embodiments, a fixing assembly is further included, the fixing assembly including a second support member 15 detachably mounted on the outer side of the side wall of the loading portion 3 , and a sixth groove is formed on the second support member 15 with an opening toward the side wall of the loading portion 3 ;

[0081] The fixing assembly further includes a third elastic member 16 connected to the bottom wall of the sixth groove, and a push plate 17 connected to one end of the third elastic member 16;

[0082] A sixth through hole communicating with the sixth groove is defined on the side wall of the loading portion 3 .

[0083] It should be noted that the size of the loading portion 3 and the position setting of the blocking component mentioned above can be adjusted according to the object itself. In actual setting, the length and width of the inner cavity of the loading portion 3 need to be larger than the length and width of the target object such as the plastic shell, so as to avoid the plastic shell from rubbing against the inner wall of the loading portion 3 when falling into the inner cavity of the loading portion 3. Under this setting, after the plastic shell falls into the inner cavity of the loading portion 3, it is easy to collide with the inner wall of the loading portion 3 repeatedly during the transfer process.

[0084] By setting up the fixing assembly, the plastic shell can be fixed after it falls into the inner cavity of the loading part 3 to avoid repeated collisions between the plastic shell and the inner wall of the loading part 3. The specific process is as follows: under the action of the third elastic member 16, the push plate 17 pushes the plastic shell from the side so that it is close to the inner wall of the loading part 3.

[0085] It should be noted that there can be multiple fixing components, and they can be set on the outside of multiple side walls of the loading part 3 to squeeze and fix the plastic shell from multiple sides; in addition, vibration damping pads can be set on the push plate 17 and the inner wall of the loading part 3.

[0086] In some embodiments, a seventh groove is formed on the side wall of the loading portion 3 on which the sixth through-hole is formed, the seventh groove being connected to the sixth through-hole and having an opening facing away from the sixth groove. An eighth groove is formed on the bottom wall of the loading portion 3, and the two ends of the eighth groove are respectively connected to the seventh groove and the first groove.

[0087] The third telescopic member 28 is connected to the wall of the seventh groove, the fourth telescopic member 29 is connected to the wall of the first groove, and the second traction member 30 is connected between the telescopic ends of the third telescopic member 28 and the fourth telescopic member 29 .

[0088] It should be noted that the structures of the third telescopic member 28 and the fourth telescopic member 29 may be the same as those of the first telescopic member 25 and the second telescopic member 26 , and the structure of the second traction member 30 may be the same as that of the first traction member 27 .

[0089] Initially, the push plate 17 is limited by the third telescopic member 28 to the outside of the inner cavity of the loading part 3. When the plastic shell moves downward so that the first elastic member 24 and the first connecting member 11 gradually enter the first groove, the first elastic member 24 and the first connecting member 11 can squeeze the fourth telescopic member 29 to cause it to shrink. At the same time, the fourth telescopic member 29 pulls the third telescopic member 28 to shrink through the second traction member 30, so as to release the limit of the push plate 17 by the third telescopic member 28, thereby realizing the automatic fixation of the plastic shell by the fixing assembly.

[0090] In some embodiments, a transport portion 4 is further included. The transport portion 4 is placed at the bottom of the loading portion 3 and is used to transfer the loading portion 3 .

[0091] To reduce manual operations, after the loading portion 3 is placed on the transport portion 4 manually or by existing devices, the transport portion 4 transfers the loading portion 3 to be in a loaded state and moves it out of the second through-hole 34 after loading is completed.

[0092] In some cases, the transport unit 4 may be configured as a conveyor, a single-axis robot, or the like.

[0093] In some embodiments, the first support member 13 is provided with a seventh through-hole vertically extending through the first support member 13 , the seventh through-hole being inserted with an inserting plate 21 , and the upper end of the side wall of the inserting plate 21 being rotatably connected to a third rotating member 22 ;

[0094] The outer side of the side wall of the loading portion 3 away from the inserting plate 21 is connected to the third connecting member 23 . The third connecting member 23 is provided with an eighth through hole which passes through the third connecting member 23 in a vertical direction.

[0095] When there is a certain angle between the third rotating member 22 and the plug plate 21, the third rotating member 22 supports the plug plate 21 so that part of its structure is above the first supporting member 13; when the third rotating member 22 rotates to be parallel to the plug plate 21, the plug plate 21 falls and can be inserted into the eighth through-hole so that when multiple loading parts 3 are set, two adjacent loading parts 3 can maintain synchronous movement in the horizontal direction, thereby avoiding the need to adjust each loading part 3 in sequence to make it accurately enter the predetermined receiving area.

[0096] In some embodiments, a material storage portion 32 is placed on the top of the inlet of the injection molding part 1. The material storage portion 32 has a material storage cavity with an opening facing the horizontal direction. A blocking portion 33 is slidably connected to the opening of the material storage cavity.

[0097] A plurality of partitions 37 spaced apart in the vertical direction are rotatably connected to the inner side of the side wall of the storage portion 32. A second stopper 38 is placed at the bottom of each partition 37. The second stopper 38 is slidably connected to the inner wall of the storage portion 32.

[0098] A ninth through hole is formed at the bottom of the material storage portion 32 and is connected to the material inlet of the injection molding portion 1 .

[0099] The material storage section 32 is used to transport raw materials to the inlet of the injection molding section 1. The inner cavity of the material storage section 32 is divided into multiple material storage cavities by the partition 37 and the second limiter 38. When the second limiter 38 is removed, the corresponding partition 37 rotates, and the raw materials enter the inlet of the injection molding section 1 through the ninth through-hole.

[0100] By dividing the inner cavity of the material storage portion 32 into a plurality of material storage cavities, the feeding process of the raw materials stored in the inner cavity of the material storage portion 32 can be controlled to avoid injecting too much or too little raw materials at one time.

[0101] It should be noted that when removing the second limiting members 38 , each second limiting member 38 needs to be removed in sequence from bottom to top.

[0102] In some embodiments, the second limiting member 38 is connected to a handle 39 , and the handle 39 is disposed outside the material storage portion 32 ;

[0103] A fourth rotating member 40 is rotatably connected to the side of the top of each handle 39 away from the material storage portion 32. A tenth through-hole is formed on the side of the bottom of each handle 39 away from the material storage portion 32. A fifth rotating member 43 is rotatably connected to the wall of each tenth through-hole. A third limiting member 44 is provided on the side of each fifth rotating member 43 away from the material storage portion 32. Each third limiting member 44 is slidably connected to an adjacent handle 39.

[0104] A third traction member is connected between the at least one fourth rotation member 40 and the handle 39 located above and closest to the fourth rotation member 40 .

[0105] When there are two handles 39, the handles 39 can be divided into a first handle 39 and a second handle 39 from bottom to top. In this case, a third pulling member can be connected between a fourth rotating member 40 (hereinafter referred to as the target rotating member) rotatably connected to the first handle 39 and the second handle 39. Initially, one end of the target rotating member faces away from the material storage portion 32. When the target rotating member moves away from the material storage portion 32 along with the first handle 39, the second handle 39 pulls the target rotating member through the corresponding third pulling member so that one end faces toward the material storage portion 32. When the target rotating member returns to its original position, it pushes the corresponding fifth rotating member 43 to rotate. Thereafter, due to the limitation of the corresponding third limiting member 44, the target rotating member is restricted to the area between the third limiting member 44 and the material storage portion 32, thereby allowing the first handle 39 and the second handle 39 to maintain synchronous movement.

[0106] In some embodiments, a sliding member 6 is slidably connected to one side of the transport portion 4, a sixth rotating member 7 is movably sleeved on the outer side of the sliding member 6, and a connecting portion 8 is connected to the end of the transport portion 4 away from the injection molding portion 1, and a fourth elastic member 9 is connected between the connecting portion 8 and the sixth rotating member 7;

[0107] The transport portion 4 is connected to a fourth limiting member 10 corresponding to the sliding member 6;

[0108] A fourth pulling member 41 is connected to the handle 39 near the inlet of the injection molding part 1. One end of the fourth pulling member 41 passes through the connecting part 8 and is then connected to the sliding member 6.

[0109] A fifth elastic member 42 is connected between the handle 39 near the inlet of the injection molding part 1 and the injection molding part 1 .

[0110] The sixth rotating member 7 can move synchronously with the sliding member 6 and rotate relative to the sliding member 6. The second connecting member 12 can push the sixth rotating member 7 to move the sliding member 6 closer to the injection molding part 1. This movement is achieved because the fourth elastic member 9 can act on the sixth rotating member 7 to keep it moving synchronously with the sliding member 6. During the movement of the sliding member 6, the fourth pulling member 41 pulls the first handle 39 to move alone or the first handle 39 and the second handle 39 to move synchronously. During the movement, the sliding member 6 gradually contacts the fourth limiting member 10, preventing it from moving closer to the injection molding part 1. After the second connecting member 12 pushes the sixth rotating member 7 to rotate relative to the sliding member 6, the fourth elastic member 9 and the fifth elastic member 42 are configured to automatically reset the sliding member 6 and each handle 39.

[0111] By setting the above structure, the process of raw materials entering the inlet of the injection molding part 1 can be controlled when the loading part 3 approaches the predetermined receiving area, which can reduce labor input and avoid excessive raw material input.

[0112] In summary, through the provision of the loading portion 3, the plastic shell can automatically fall into the loading portion 3 after being released from the discharge port of the injection molding portion 1, thereby avoiding the additional steps of removing the plastic shell and packaging the plastic shells individually. In addition, through the provision of the first elastic member 24, the first elastic member 24 can automatically and indirectly push the second connecting member 12 to place it outside the inner cavity of the loading portion 3, while gradually slowing the falling speed of the plastic shell, thereby preventing damage to the plastic shell during the process of automatically falling into the loading portion 3. Moreover, when the plastic shell squeezes the first elastic member 24, the first elastic member 24 can indirectly pull the second connecting member 12, making it impossible for the first limiting member 36 to indirectly limit the loading portion 3, while prompting the second connecting member 12 to block the fourth through-hole 5, thereby keeping the loading portion 3 closed in the horizontal direction.
