Description

Technical Field

[0001] This application relates to the field of injection molding technology, and in particular to a feeding device. Background Technology

[0002] In related technologies, existing feeding devices on the market are primarily designed for use with horizontal injection molding machines. These devices lack clamping capabilities and can only eject components horizontally, making them suitable only for horizontal injection molding machines. When feeding components to vertical injection molding machines, the terminal pins need to be inserted from top to bottom. However, because these devices lack clamping capabilities, the terminal pins can still move vertically, making them unsuitable for vertical injection molding machines. Therefore, improving the compatibility of feeding devices is a problem that needs to be solved. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a feeding device capable of locking the workpiece, thereby enabling feeding for both horizontal and vertical injection molding machines.

[0004] According to a first aspect of the present invention, a feeding device includes: a feeding mold, a top plate, and a locking mechanism. The feeding mold has an ejection position penetrating the feeding mold, the ejection position being used to accommodate a workpiece. The top plate is elastically connected to one side of the feeding mold and has an ejector component, the ejector component being movably inserted into the ejection position for ejecting the workpiece. The locking mechanism includes a positioning component and a driving assembly connected to each other. The positioning component is disposed in the feeding mold and can be inserted into the ejection position under the drive of the driving assembly to lock the workpiece or move away from the ejection position to release the workpiece.

[0005] The feeding device according to embodiments of the present invention has at least the following advantages: the feeding device includes a feeding mold, an ejector plate, and a locking mechanism. The ejector plate is elastically connected to one side of the feeding mold and is provided with an ejector component that can be inserted into the ejection position of the feeding mold, thereby enabling the ejection action of the workpiece in the ejection position. At the same time, the feeding mold is also provided with a positioning component, which is connected to a driving assembly and can be inserted into the ejection position under the drive of the driving assembly, thereby locking the workpiece. Therefore, the feeding device of this application can lock the workpiece, thus enabling feeding to both horizontal and vertical injection molding machines.

[0006] According to some embodiments of the present invention, the driving assembly includes a first elastic component, a first wedge, and a second wedge. The first elastic component connects the positioning member and the loading mold and is used to provide the positioning member with an elastic force to lock the workpiece. The second wedge is slidably connected to the loading mold and connected to the positioning member. The second wedge is provided with a second guide surface. The first wedge is provided on the top plate and is provided with a first guide surface. When the top plate approaches the loading mold, the first guide surface can abut against the second guide surface, so that the second wedge can drive the positioning member away from the ejection position, while causing the first elastic component to deform.

[0007] According to some embodiments of the present invention, the drive assembly further includes a connecting assembly, and multiple positioning elements are provided, with the connecting assembly connecting the multiple positioning elements and the second wedge.

[0008] According to some embodiments of the present invention, the ejector position includes a communicating receiving groove and an ejector hole. The ejector hole penetrates the side of the feeding mold near the top plate for the ejector component to pass through. The receiving groove penetrates the side of the feeding mold away from the top plate, and the diameter of the receiving groove is larger than that of the ejector hole for accommodating the workpiece.

[0009] According to some embodiments of the present invention, the device further includes a guide post, a second elastic component, and a snap lock. The guide post is disposed on the loading mold and passes through the top plate. The second elastic component is disposed between the loading mold and the top plate, and is sleeved on the guide post to provide an elastic force that moves the loading mold and the top plate away from each other. One end of the snap lock is hinged to one of the loading mold and the top plate, and the other end is provided with a snap for locking the other. When the snap lock locks the loading mold and the top plate, the first guide surface abuts against the second guide surface, and the positioning member moves away from the receiving groove. When the snap lock is rotated to release the lock, the loading mold and the top plate can move away from each other under the elastic force of the second elastic component, and the positioning member can lock the workpiece under the elastic force of the first elastic component.

[0010] According to some embodiments of the present invention, a positioning part is provided on the side of the feeding mold away from the top plate, and the positioning part is adapted to the positioning groove of the mold in the injection molding machine.

[0011] According to some embodiments of the present invention, at least two positioning parts are provided, and they are distributed non-centrally and symmetrically on the side of the feeding mold away from the top plate.

[0012] According to some embodiments of the present invention, a first limiting member is further included, which is connected to the feeding mold and the top plate and is used to limit the feeding mold and the top plate from disengaging.

[0013] According to some embodiments of the present invention, a second limiting member is also included, which is disposed on the side of the feeding mold facing the top plate or the side of the top plate facing the feeding mold, so as to limit the closest distance between the feeding mold and the top plate.

[0014] According to some embodiments of the present invention, it further includes a plurality of equal-height pillars distributed on the side of the loading mold away from the top plate and used to abut against the surface of the mold in the injection molding machine.

[0015] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0030] The following is for reference. Figures 1 to 6 The feeding device of an embodiment of the present invention is described.

[0031] like Figures 1 to 5As shown, the feeding device according to an embodiment of the present invention includes: a feeding mold 100, a top plate 200, and a locking mechanism 300. The feeding mold 100 is provided with an ejection position 101 that penetrates the feeding mold 100, and the ejection position 101 is used to accommodate a workpiece 500. The top plate 200 is elastically connected to one side of the feeding mold 100 and is provided with an ejector 210. The ejector 210 is movably inserted into the ejection position 101 for ejecting the workpiece 500. The locking mechanism 300 includes a positioning member 310 and a driving assembly that are interconnected. The positioning member 310 is provided in the feeding mold 100 and can be inserted into the ejection position 101 under the drive of the driving assembly to lock the workpiece 500 or move away from the ejection position 101 to release the workpiece 500.

[0032] It is understood that this feeding device includes a feeding mold 100, an ejector plate 200, and a locking mechanism 300. The ejector plate 200 is elastically connected to one side of the feeding mold 100 and is provided with an ejector component 210 that can be inserted into the ejection position 101 of the feeding mold 100, thereby enabling the ejection action of the workpiece 500 in the ejection position 101. At the same time, the feeding mold 100 is also provided with a positioning component 310, which is connected to a drive assembly and can be inserted into the ejection position 101 under the drive of the drive assembly, thereby locking the workpiece 500. Therefore, the feeding device of this application can lock the workpiece 500, thus enabling feeding to both horizontal and vertical injection molding machines.

[0033] It is understood that the driving assembly includes a first elastic component 321, a first wedge 322, and a second wedge 323. The first elastic component 321 connects the positioning member 310 and the loading mold 100, and provides the positioning member 310 with an elastic force to lock the workpiece 500. The second wedge 323 is slidably connected to the loading mold 100 and connected to the positioning member 310. The second wedge 323 has a second guide surface 3231. The first wedge 322 is located on the top plate 200 and has a first guide surface 3221. When the top plate 200 approaches the loading mold 100, the first guide surface 3221 can abut against the second guide surface 3231, so that the second wedge 323 can drive the positioning member 310 away from the ejection position 101, while causing the first elastic component 321 to deform. For example, as... Figures 1 to 2As shown, in this embodiment, the top plate 200 is provided with a first wedge 322, which has a first guide surface 3221. The loading mold 100 is provided with a second wedge 323, which has a second guide surface 3231. The second wedge 323 is connected to the positioning member 310, and the first elastic component 321 connects the positioning member 310 and the loading mold 100. When the top plate 200 approaches the loading mold 100 under the action of an external force, the first guide surface 3221 of the first wedge 322 abuts against the second guide surface 3231 of the second wedge 323, thereby enabling the second wedge 323 to drive the positioning member 310. The ejector plate 200 moves away from the ejector position 101 to facilitate the loading of the workpiece 500 onto the upper mold 100 or to allow the already loaded mold 100 to eject the workpiece 500 onto the injection molding machine under the action of the ejector 210. At the same time, the first elastic component 321 connecting the positioning component 310 and the upper mold 100 undergoes elastic deformation. When the ejector plate 200 moves away from the upper mold 100, the second guide surface 3231 of the second wedge 323 is no longer supported by the first guide surface 3221 of the first wedge 322. Under the elastic force of the first elastic component 321, the positioning component 310 can insert into the ejector position 101, thereby achieving the positioning of the workpiece 500.

[0034] Specifically, the first guide surface 3221 and the second guide surface 3231 can be curved surfaces or inclined surfaces.

[0035] It is understood that the drive assembly also includes a connecting component 324, and multiple positioning members 310 are provided. The connecting component 324 connects the multiple positioning members 310 and the second wedge member 323. For example, as Figure 1 As shown, in this embodiment, the connecting component 324 is slidably connected to the feeding mold 100. The connecting component 324 is used to connect the second wedge 323 and multiple positioning components 310. Thus, when the first wedge 322 abuts against the second wedge 323, the second wedge 323 can drive the multiple positioning components 310 away from the ejection position 101 through the connecting component 324, thereby unlocking the multiple workpieces 500. When the first wedge 322 moves away from the second wedge 323, the multiple workpieces 500 can be locked again under the elastic force of the first elastic component 321.

[0036] It is understood that the ejector position 101 includes a communicating receiving groove 102 and an ejector hole 103. The ejector hole 103 penetrates the side of the loading mold 100 near the ejector plate 200 to allow the ejector component 210 to pass through. The receiving groove 102 penetrates the side of the loading mold 100 away from the ejector plate 200, and the diameter of the receiving groove 102 is larger than that of the ejector hole 103 to accommodate the workpiece 500. For example, as Figures 4 to 5As shown, in this embodiment, the ejector position 101 includes a receiving groove 102 that penetrates the side of the loading mold 100 away from the top plate 200 and an ejection hole 103 that penetrates the side of the loading mold 100 near the top plate 200. The receiving groove 102 and the ejection hole 103 are connected, and the hole diameter is larger than the ejection hole 103, so that the workpiece 500 can be inserted into the receiving groove 102 and placed in the receiving groove 102. When the top plate and the loading mold 100 are close, the ejector 210 is inserted into the ejection hole 103 and can eject the workpiece 500 in the receiving groove 102.

[0037] Specifically, the workpiece 500 has a protrusion with a large outer diameter in the middle. When the workpiece 500 is inserted into the ejector position 101, the inserted end of the workpiece 500 can pass through the receiving groove 102 and be inserted into the ejector hole 103 until the protrusion of the workpiece 500 abuts against the bottom of the receiving groove 102. The protrusion has a notch. When the positioning member 310 is inserted laterally into the ejector position, it abuts against the notch surface of the protrusion of the workpiece 500, thereby locking the workpiece 500.

[0038] Understandably, it also includes a guide post 410, a second elastic component 420, and a snap lock 430. The guide post 410 is disposed on the loading mold 100 and passes through the top plate 200. The second elastic component 420 is disposed between the loading mold 100 and the top plate 200. The second elastic component 420 is sleeved on the guide post 410 and is used to provide an elastic force that keeps the loading mold 100 and the top plate 200 away from each other. One end of the snap lock 430 is hinged to one of the loading mold 100 and the top plate 200, and the other end... One end is provided with a buckle 431 for locking the other; wherein, when the buckle lock 430 locks the loading mold 100 and the top plate 200, the first guide surface 3221 abuts against the second guide surface 3231, and the positioning member 310 moves away from the receiving groove 102. When the buckle lock 430 is rotated to release the lock, the loading mold 100 and the top plate 200 can move away from each other under the elastic force of the second elastic component 420, and the positioning member 310 can lock the workpiece 500 under the elastic force of the first elastic component 321.

[0039] For example, such as Figures 1 to 5As shown, in this embodiment, the loading mold 100 is provided with a guide post 410, which passes through the top plate 200. The second elastic component 420 is sleeved on the guide post 410 and disposed between the loading mold 100 and the top plate 200. It is used to provide an elastic force that causes the loading mold 100 and the top plate 200 to move away from each other. One end of the overlock 430 is hinged to one of the loading mold 100 and the top plate 200, and the overlock 431 at the other end can lock the other of the loading mold 100 and the top plate 200, thereby restricting the loading mold 100 and the top plate 200 from moving away from each other under the action of elastic force. In this way, at the beginning of use, the top plate 200 can be pressed against the upper die 100, so that the first guide surface 3221 of the first wedge 322 can abut against the second guide surface 3231 of the second wedge 323, causing the positioning member 310 to move away from the ejection position 101. Then, the end of the undercut lock 430 with the undercut 431 is fastened to the upper die 100 or the top plate 200 to lock the upper die 100 and the top plate 200. At this time, the workpiece 500 can be loaded into the upper feeding device. After the workpiece 500 is loaded into the upper feeding device, the undercut lock 430 is released from the upper die 100 and the top plate 200. With the locking of 00, the first wedge 322 and the second wedge 323 also move away from each other, so that the positioning member 310 locks the workpiece 500 under the action of the first elastic component 321; then when the workpiece 500 in the feeding device is fed into the injection molding machine, the top plate 200 is pressed against the upper mold 100, and the second wedge 323, under the resistance of the first wedge 322, drives the positioning member 310 away from the ejection position 101, and the ejector member 210 of the top plate 200 inserts into the ejection position 101 to push the workpiece 500 out of the feeding mold 100, thereby realizing the feeding process of the feeding device to the injection molding machine.

[0040] Understandably, the loading mold 100 has a positioning part 110 on the side opposite to the ejector plate, and the positioning part 110 is adapted to the positioning groove of the mold in the injection molding machine. For example, as Figure 6 As shown, in this embodiment, the positioning part 110 provided on the side of the feeding mold 100 away from the fixed plate can be adapted to the positioning groove in the injection molding machine mold and inserted into the positioning groove, thereby realizing the alignment of the feeding device and the injection molding machine mold.

[0041] It is understood that at least two positioning parts 110 are provided, and they are distributed non-centrally and symmetrically on the side of the loading mold 100 away from the top plate. For example, as Figure 6 As shown, in this embodiment, the non-centrally symmetrical arrangement of at least two positioning parts 110 can effectively prevent mistaken insertion and avoid reverse insertion with the injection molding machine mold.

[0042] Understandably, it also includes a first limiting member 440, which connects the loading mold 100 and the top plate 200, and is used to prevent the loading mold 100 and the top plate 200 from disengaging. For example, as Figures 3 to 4 As shown, in this embodiment, the first limiting member 440 can effectively prevent the feeding mold 100 and the top plate 200 from separating from each other under the elastic force of the second elastic component 420, thus achieving effective connection.

[0043] Understandably, it also includes a second limiting member 450, which is disposed on the side of the loading mold 100 facing the top plate 200 or the side of the top plate 200 facing the loading mold 100, to limit the closest distance between the loading mold 100 and the top plate 200. For example, as Figures 4 to 6 As shown, in this embodiment, the second limiting member 450 is set between the loading mold 100 and the ejector plate 200. Therefore, during the process of loading the workpiece 500 from the loading device into the injection molding machine, when the ejector plate 200 can no longer approach the loading mold 100 under the limitation of the second limiting member 450, that is, the ejector plate 200 ejects the workpiece 500 into place, thus avoiding collision damage between the workpiece 500 and the injection molding machine mold.

[0044] Understandably, it also includes multiple equal-height pillars 120, distributed on the side of the loading mold 100 facing away from the ejector plate 200, and used to abut against the surface of the mold in the injection molding machine. For example, as... Figure 6 As shown, in this embodiment, by distributing multiple equal-height columns 120 on the side of the feeding mold 100 away from the top plate 200, the flatness of the feeding mold 100 and the injection molding machine mold during the feeding process of the feeding device is achieved, ensuring the consistency of the depth of the workpiece 500 entering the injection molding machine, and ultimately improving the processing accuracy of the injection molded parts produced by the injection molding machine.

[0045] It should be understood that a plurality of protruding positioning parts 110 are provided on the side of the feeding mold 100 away from the top plate 200. The ejector position 101 passes through the feeding mold 100 and the positioning part 110, and supports the workpiece 500 through the positioning part 110. By setting the positioning part 110, the number of ejector positions 101 that can accommodate the workpiece 500 can be increased, thereby increasing the number of workpieces 500 that can be fed at one time.

[0046] It should be understood that a guide member 220 is provided on the side of the top plate 200 facing the loading mold 100, and the top member 210 is provided on the top plate 200 and passes through the guide member 220, thereby improving the linearity of the movement of the top member 210.

[0047] It should be understood that a handle 230 is provided on the side of the top plate 200 facing away from the feeding mold 100, so the feeding device can be manually assisted by grasping the handle 230 to feed the material.

[0048] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
