Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a waste material removing device for injection molded parts. Background Art

[0002] The steel sheets of some injection-molded parts are small in size and require epitaxial steel sheets as auxiliary supports during the processing. Positioning holes are also added to the epitaxial steel sheets. In addition, there are runners connecting the newly injection-molded injection-molded parts. Therefore, the runners need to be removed first, and then the excess epitaxial steel sheets need to be removed as scrap steel sheets to obtain the final injection-molded products.

[0003] Currently, manual assisted operation is often used. First, the newly injection-molded injection molded parts are visually positioned and the runners are removed by an ultrasonic die head. Then, the injection molded parts with only the epitaxial steel sheets left are visually positioned and the epitaxial steel sheets are separated from the injection molded parts by a steel sheet breaking machine. This operation method is time-consuming, labor-intensive, and has low operating efficiency. Utility Model Content

[0024] To further illustrate various embodiments, the present invention is provided with accompanying drawings. These drawings form part of the disclosure of this invention and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, those skilled in the art will understand other possible implementations and the advantages of this invention. The components in the figures are not drawn to scale, and similar reference numerals are generally used to represent similar components.

[0025] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0026] Reference Figure 1 and Figure 6 As shown, this embodiment provides a waste removal device for injection molded parts (hereinafter referred to as the waste removal device) for removing waste from injection molded parts that have just been injection molded, and the waste of the injection molded parts 1 includes scrap steel sheets 11 connected to the injection molded parts 1 and a runner 12 connected between the two injection molded parts 1.

[0027] The waste removal device of this embodiment includes a conveying mechanism, a material receiving mechanism 6 , two positioning jigs 4 for carrying the injection molded part 1 , a runner removal mechanism 2 for removing the runner 12 , and a scrap steel sheet removal mechanism 3 for removing the scrap steel sheet 11 .

[0028] The two flow channel removal mechanisms 2 and scrap steel sheet removal mechanisms 3 are arranged in a transverse arrangement, and the arrangement direction of the flow channel removal mechanism 2 is parallel to the arrangement direction of the scrap steel sheet removal mechanism 3, and the flow channel removal mechanism 2 and the scrap steel sheet removal mechanism 3 are in one-to-one correspondence.

[0029] The conveying mechanism includes two longitudinal drive components 5 for driving the longitudinal movement of the positioning jig 4 and a finished product conveying component 8 for conveying the processed injection molded parts 1 on the positioning jig 4 to the receiving mechanism 6. The finished product conveying component 8 is arranged between the runner removal mechanism 2 and the scrap steel sheet removal mechanism 3, and a corresponding longitudinal drive component 5 is arranged between the runner removal mechanism 2 and the scrap steel sheet removal mechanism 3 on each vertical column to drive the corresponding positioning jig 4 to move back and forth between the feed port 24 of the runner removal mechanism 2, the feed port of the finished product conveying component 8 and the feed port of the scrap steel sheet removal mechanism 3 to form two independent and parallel waste removal systems.

[0030] The waste removal device of this embodiment further includes a frame 7 , and the conveying mechanism, the material receiving mechanism 6 , the flow channel removal mechanism 2 and the scrap steel sheet removal mechanism 3 are all assembled on the frame 7 .

[0031] In this embodiment, the material receiving mechanism 6 includes a finished product transfer tray 61 for holding the processed injection molded parts 1, and the finished product handling assembly 8 includes a transverse motion module, a longitudinal motion module assembled on the moving end of the transverse motion module, and a suction cup assembled on the moving end of the longitudinal motion module. When one of the positioning fixtures 4 is moved to the feed port of the finished product handling assembly 8, the suction cup is used to simultaneously absorb multiple processed injection molded parts 1 on the positioning fixture 4, so as to transport the injection molded parts 1 processed by the two waste removal systems to the finished product transfer tray 61 in sequence, and at the same time ensure that the injection molded parts 1 on the finished product transfer tray 61 are neatly arranged.

[0032] The specific longitudinal drive assembly 5 can be a synchronous conveyor belt assembly or a drive assembly composed of multiple cylinders, etc., and is not limited to other forms of transplanting drive methods. In this way, the longitudinal drive of the positioning fixture can also be achieved.

[0033] More specifically, Figure 2 and Figure 3As shown, the positioning jig 4 is provided with a placement groove 41 for supporting the injection molded part 1, as well as four positioning pins 42 and six liftable limit pins 43. The positioning pins 42 are used to limit and position the flow channel 12. Specifically, the positioning pins 42 are fixed pins. When the flow channel 12 is located between the positioning pins 42, the positioning pins 42 realize rough positioning of the relative position of the injection molded part 1 on the positioning jig 4, and then the limit pins 43 correspond one by one to the through holes of the scrap steel sheet 11. When the injection molded part 1 just after injection molding is placed in the placement groove 41 of the positioning jig 4, the limit pins 43 are driven upward by the provided cylinder, and then are sleeved in the through holes of the scrap steel sheet 11 to realize precise positioning of the injection molded part 1 on the positioning jig 4.

[0034] In addition, a clearance window 411 is provided at the bottom of the placement groove 41 and passes through the upper and lower surfaces thereof. The clearance window 411 corresponds to the connection between the scrap steel sheet 11 and the injection molded part 1 to cooperate with the scrap steel sheet removal mechanism 3 to remove the scrap steel sheet 11.

[0035] like Figure 4 As shown, the runner removal mechanism 2 includes a first driver 21, an ultrasonic transducer 22, and an ultrasonic die 23 mounted on the ultrasonic transducer 22. The first driver 21 drives the ultrasonic transducer 22 to drive the ultrasonic transducer 22 and the ultrasonic die 23 to rise and fall. The ultrasonic die 23 corresponds to the runner 12 to form a runner 12 removal arrangement. The two runner removal mechanisms 2 are respectively a first runner removal mechanism and a second runner removal mechanism. Directly below the ultrasonic die 23 of the first runner removal mechanism and the second runner removal mechanism are formed a first runner removal station and a second runner removal station that are independent of each other. Of course, in other embodiments, the runner removal mechanism 2 can also use a cutter structure to remove the runner 12.

[0036] like Figure 5 As shown, the scrap removal mechanism 3 includes a second driver 33, a third driver 34, an upper blade 31 and a lower blade 32 that can be raised and lowered, and a fourth driver 35 mounted on the lifting end of the third driver 34. The upper blade 31 and the lower blade 32 are arranged in an upper and lower position. The second driver 33 is used to drive the lower blade 32 to rise and fall. The third driver 34 is mounted on the frame 7. The fourth driver 35 is used to drive the upper blade 31 to rise and fall. The two scrap removal mechanisms 3 are respectively a first scrap removal mechanism and a second scrap removal mechanism. The upper and lower blades of the first and second scrap removal mechanisms form a first and a second independent scrap removal station. Of course, in other embodiments, the scrap removal mechanism 3 can also use ultrasonic technology to remove scrap 11.

[0037] In this specific embodiment, the first driver 21 and the third driver 34 are both lifting cylinders, the second driver 33 is a micro cylinder, and the fourth driver 35 is a three-axis cylinder.

[0038] There are two longitudinal drive assemblies 5 , namely a first longitudinal drive assembly and a second longitudinal drive assembly.

[0039] There are two positioning jigs, namely a first positioning jig and a second positioning jig.

[0040] The first runner removal mechanism, the first scrap steel sheet removal mechanism, the first positioning fixture, the first longitudinal drive assembly, the finished product transport assembly 8 and the material receiving mechanism 6 constitute a first scrap removal system.

[0041] The second runner removal mechanism, the second scrap steel sheet removal mechanism, the second positioning fixture, the second longitudinal drive assembly, the finished product transport assembly 8 and the material receiving mechanism 6 constitute a second waste removal system.

[0042] During specific implementation, the waste removal device of this embodiment is externally provided with a six-axis robot to simultaneously place a plurality of newly injection-molded injection molded parts 1 on the positioning jig 4 located at the inlet 24 of the first runner removal mechanism. At this time, the runner 12 is slightly lifted by the protrusion of the positioning jig 4, and then the positioning jig 4 is driven to the first runner removal station. Thereafter, the first driver 21 drives the ultrasonic transducer 22 and the ultrasonic die 23 to move downward synchronously until the ultrasonic die 23 abuts against the runner 12. Thereafter, the ultrasonic energy generated by the ultrasonic transducer 22 is transmitted to the runner 12 through the ultrasonic die 23, so as to achieve the breaking of the weak connection between the runner 12 and the injection molded part 1. After the runner 12 is separated from the injection molded part 1, the injection molded part 1 and the scrap steel sheet 11 simultaneously descend along the guide direction of the limit needle 43 until they abut against the bottom of the placement groove 41.

[0043] When the positioning jig 4 is driven to the first scrap steel sheet removal station, the third driver 34 and the cooperation of the guide shaft 36 and the linear bearing on the frame 7 drive the tool holder of the upper inserting knife 31 to move downward until it abuts the first positioning jig. Then, the fourth driver 35 drives the upper inserting knife 31 to continue to move downward and extend downward into the clearance window 411 of the first positioning jig, so that the upper inserting knife 31 bends the scrap steel sheet 11 downward. Then, the fourth driver 35 drives the upper inserting knife 31 to move upward to the initial position.

[0044] Then the second driver 33 drives the lower blade 32 to move upward and extend upward into the clearance window 411 of the first positioning fixture, so that the lower blade 32 bends the scrap steel sheet 11 upward. After the scrap steel sheet 11 is repeatedly bent back and forth in the up and down directions, the connection between the scrap steel sheet 11 and the injection molded part 1 is broken, falls off, and is separated from the injection molded part 1.

[0045] When the first positioning jig equipped with the processed injection-molded parts 1 is moved to the feed port of the finished product handling assembly 8, the suction cup sucks all the injection-molded parts 1 on the first positioning jig through the cooperation of the lateral motion module and the longitudinal motion module. At the same time, the limit pin 43 is driven by the equipped cylinder to retract and disengage downward to avoid interfering with the transportation of the injection-molded parts 1. The injection-molded parts 1 are then transferred to the finished product transfer tray 61, and the tray swinging action is completed synchronously, thereby completing the waste removal operation of the first waste removal system.

[0046] Likewise, the operating steps of the second waste removal system are similar to those of the first waste removal system and will not be described in detail herein.

[0047] By arranging the runner removal mechanism 2 and the scrap steel sheet removal mechanism 3 horizontally side by side into two rows, and through the cooperation of the longitudinal drive component 5 and the positioning fixture 4, a compact layout with multiple stations and fast production rhythm is realized, and then through the cooperation of the material collection mechanism 6 and the finished product handling component 8, it is ensured that the processed injection molded parts 1 are quickly placed and collected, so that the waste removal operation of the injection molded parts 1 is time-saving and labor-saving, and the operating efficiency is effectively improved.

[0048] In addition, the positioning fixture 4 is used to accurately position the injection molded part 1 and the waste material to avoid manual positioning operations. This ensures the stability of the ultrasonic runner removal and scrap steel sheet breaking operations, thereby ensuring the stability of the injection molded part product quality.

[0049] Of course, the number of waste removal systems may be 1 or 3 or more.

[0050] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the form and details of the present invention without departing from the spirit and scope of the present invention as defined by the appended claims, and all of these changes are within the scope of protection of the present invention.
