Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and in particular to a molding die. Background Technology

[0002] After injection molding, the molded part is ejected by an ejection mechanism for easy demolding. However, the ejection mechanism can easily scratch the part during the ejection process, leading to a decrease in the yield of the molded parts. Furthermore, the robot arm can easily interfere with the ejection mechanism when picking up the molded part. Therefore, optimizing the ejection process and the subsequent picking up of the molded part are problems that need to be solved. Utility Model Content

In the following detailed description of the present invention, certain specific details are described in detail. Those skilled in the art will fully understand the present invention even without these details. To avoid obscuring the essence of the present invention, well-known methods, processes, flows, elements, and circuits are not described in detail.

[0084] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0085] Unless the context explicitly requires it, words such as "including" or "contains" throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to".

[0086] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0087] Unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0088] For ease of explanation, spatially related terms such as “inside,” “outside,” “below,” “below,” “lower,” “above,” “upper,” etc., are used herein to describe the relationship between one element or feature illustrated in the figure and another. It will be understood that spatially related terms may be intended to encompass different orientations of the device in use or operation besides those depicted in the figure.

The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially related descriptive terms used herein should be interpreted accordingly.

[0089] Figure 1 and Figure 2 This is a schematic diagram of the molding die in this embodiment.

[0090] In some implementations, such as Figures 1-2 As shown, the molding die in this embodiment includes a first molding component 5 and a second molding component (not shown in the figure). The second molding component is located above the first molding component 5. The first molding component 5 includes a mold core 2 and an ejector portion 1.

Figure 6 and Figure 7 This is an exploded view of the first molding component 5 in this embodiment. Figure 8 This is a schematic diagram showing the positional relationship between the driving component 31, the second driving plate 71, and the third driving plate 72 in this embodiment.

[0092] Further reference Figures 3-5 As shown, when the first molding assembly 5 and the second molding assembly are aligned, the second molding assembly and the molding groove 4 form an injection cavity. The workpiece 6 is molded within this injection cavity. When the second molding assembly is lifted from the first molding assembly 5, the top of the workpiece 6 located in the molding groove 4 is exposed. The first drive unit 3 can drive the ejector rod 12 to move upward, and the second drive unit 7 can drive the ejector 11 to move upward, thereby using the ejector 11 to eject the workpiece 6 from the molding groove 4. This facilitates the removal of the workpiece 6 by an operator or robot.

[0093] Figure 9 This is a schematic diagram of the structure of the mold core 2, the ejector part 1 and the drive component 31 in this embodiment. Figure 10 This is an exploded view of the mold core 2, the ejector part 1, and the drive member 31 in this embodiment. Figure 11This is an exploded view of the mold core 2 and the ejector 11 in this embodiment.

[0094] Further reference Figures 9-11 As shown, the mold core 2 has a forming area 21 and two inclined slides 22. A through hole 23 is formed on the bottom surface of the forming area 21. The two inclined slides 22 are inclined relative to the through hole 23, and their inclination directions are opposite. The ejector part 1 includes an ejector rod 12 and two ejector members 11. Each ejector member 11 includes a guide rod 111 and a forming block 112 disposed on the guide rod 111. Simultaneously, the inclined slide 22, near the end of the forming block 112, is inclined towards the side of the forming block 112 opposite to the forming surface 1121.

[0095] Specifically, such as Figure 11 As shown, the mold core 2 has two through holes 23. The two through holes 23 are located on the first plane. Dashed line I is the projection of the center line of the upper through hole 23 onto the first plane, and this through hole 23 extends vertically. The two dashed lines II are the projections of the center lines of the two inclined slides 22 onto the first plane, and the two dashed lines II are at the same angle to dashed line I. Moreover, the ends of the two dashed lines II that are away from the molding area 21 are far apart from each other.

[0096] Figure 12 This is a schematic diagram of the structure of the first drive board 32, the second drive board 71, the third drive board 72 and the position adjustment unit 8 in this embodiment. Figure 13 yes Figure 1 Schematic diagram of cross-section at point BB. Figure 14 , Figure 15 and Figure 16 This is a schematic diagram of the working state of the position adjustment unit 8 in this embodiment. The outlines of the first drive plate 32 and the adjustment rod 82 are shown with thick solid lines. Figure 17 and Figure 18 This is a schematic diagram of the working state of the ejector section 1 in this embodiment.

[0097] Further reference Figures 12-18 As shown, driven by the first drive unit 3, the push rod 12 is movably inserted through the through hole 23. Driven by the second drive unit 7, the two guide rods 111 are movably inserted through the two inclined slides 22 respectively. The opposite sides of the two molding blocks 112 form molding surfaces 1121, and the two molding surfaces 1121 merge with the molding area 21 and the end face of the push rod 12 to form molding grooves 4. The guide rods 111 move upward along the inclined slides 22, and the two molding blocks 112 move away from each other.

[0098] Specifically, when the ejector pin 12 is not ejected, the end face of the ejector pin 12 is flush with the bottom surface of the forming area 21. The two forming surfaces 1121 are symmetrically arranged with respect to the center of the forming area 21. During the process of the ejector part 1 lifting the workpiece 6 upwards, the ejector part 1 is configured such that the ejector pin 12 and the ejector part 11 move upwards synchronously (e.g., ...). Figure 17 As shown), this causes the workpiece 6 to detach from the forming area 21. Simultaneously, the two forming blocks 112 move away from each other horizontally, and both forming areas 21 detach from the workpiece 6, ensuring that the workpiece 6 remains at the top of the ejector pin 12. This prevents the workpiece 6 from shifting position or falling off the ejector pin 12 due to inconsistent movement of the two forming blocks 112. Then, as... Figure 18 As shown, keeping the ejector 11 stationary, the drive rod 12 continues to move upward until the workpiece 6 moves above the two forming blocks 112. This simplifies the picking process for the robotic arm.

[0099] Optionally, the molding die can be applied to either metal injection molding or non-metal injection molding. Taking metal injection molding as an example, the molding die can be applied to metal injection molding. The material of workpiece 6 can be a mixture of metal powder and binder.

[0100] In summary, the molding die in this embodiment has an inclined slide 22 and a through hole 23 on the mold core 2, with a guide rod 111 passing through the inclined slide 22 and an ejector rod 12 passing through the through hole 23. Simultaneously, a molding groove 4 is formed by the molding area 21, the two molding surfaces 1121, and the top surface of the ejector rod 12. Thus, on the one hand, the ejector 11 and ejector rod 12 simultaneously eject the workpiece 6, ensuring successful separation of the workpiece 6 from the molding area 21, allowing the workpiece 6 to be stably positioned on the ejector part 1. On the other hand, the two inclined slides 22 are inclined relative to the through hole 23, and the inclination directions of the two inclined slides 22 are opposite. As the guide rod 111 moves along the inclined slide 22, the two molding blocks 112 move away from each other, allowing the two molding surfaces 1121 to gradually separate from the workpiece 6. When the ejector rod 12 lifts the workpiece 6 again, the molding surfaces 1121 will not damage the workpiece 6, improving the yield rate and reducing the difficulty of picking up the workpiece by the robot arm.

[0101] In some implementations, such as Figures 10-11 As shown, the molding surface 1121 has a protruding flange 1122, which extends circumferentially along the push rod 12. There are two through holes 23 and two push rods 12, and the arrangement direction of the two push rods 12 is consistent with the arrangement direction of the two molding blocks 112. Further referencing... Figure 17 As shown, the ejector 1 ejects the workpiece 6 from the forming zone 21, the two ejector rods 12 extend from the two through holes 23 respectively, and the two forming surfaces 1121 move to both sides of the workpiece 6.

[0102] Specifically, such as Figure 3 , Figure 4 , Figure 5 and Figure 11As shown, a protrusion 211 protrudes from the bottom of the forming area 21, and two through holes 23 are located on both sides of the protrusion 211. In this embodiment, the protrusion 211 is used to form the second groove 62 of the workpiece 6, and the flange 1122 is used to form the first groove 61 of the workpiece 6. The second groove 62 can be separated from the protrusion 211 by using two push rods 12, and the flange 1122 can be gradually separated from the first groove 61 by using the cooperation of the inclined slide 22 and the guide rod 111, so as to avoid the flange 1122 scratching the side wall of the first groove 61.

[0103] In some implementations, such as Figure 11 As shown, the mold core 2 has a receiving groove 24, and the bottom surface of the receiving groove 24 has a molding area 21 and two inclined slides 22. The molding area 21 is located in the middle of the receiving groove 24, and the two inclined slides 22 pass through the mold core 2 and are located on both sides of the molding area 21. Further referencing... Figure 3 As shown, when the two molding surfaces 1121 are aligned, the two molding blocks 112 enter the receiving groove 24 and the bottom of the molding block 112 abuts against the bottom of the receiving groove 24.

[0104] In this configuration, the two molding blocks 112 are partially offset along their length, and the top of the molding block 112 is flush with the top of the mold core 2, so as to facilitate cooperation with the second molding component. In addition, the bottom of the receiving groove 24 can limit the height of the molding surface 1121 to ensure that the heights of the two molding blocks 112 are consistent.

[0105] In some implementations, such as Figures 10-11 As shown, the guide rod 111 is inclined and includes a first connecting end 1111 and a sliding end 1112, with the first connecting end 1111 connected to the molding block 112. Further referencing... Figures 6-7 As shown, the molding die also includes a first driving unit 3. The first driving unit 3 includes a driving member 31, which has two first sliding grooves 311 corresponding to the two guide rods 111. The two first sliding grooves 311 extend parallel to each other towards the molding area 21, and the sliding end 1112 extends into the corresponding first sliding groove 311. Further referring to… Figure 17 As shown, when the driving member 31 drives the two ejector members 11 to move along the axial direction of the push rod 12, the sliding end 1112 is engaged in the first slide groove 311 and slides along the extension direction of the first slide groove 311.

[0106] In this embodiment, the first groove 311 cooperates with the inclined slide 22 to drive the ejector 11 to move upward and simultaneously move horizontally, so that when the forming block 112 moves the workpiece 6 upward, it gradually moves away from the first groove 61, which helps to ensure the dimensional tolerance of the workpiece 6.

[0107] In some implementations, such as Figures 9-11As shown, the driving member 31 has a first clearance hole 312, which passes through the driving member 31 and is located between the two first sliding grooves 311. The push rod 12 has an ejector end 121 and a fixed end 122. The ejector end 121 passes through the first clearance hole 312, and the end face of the ejector end 121 forms a portion of the forming groove 4. Further referencing... Figures 6-7 As shown, the molding die also includes a second driving part 7, which drives the ejector end 121 to move via the fixed end 122. The first clearance hole 312 provided in this embodiment makes the structure of the ejector part 1 more compact and avoids interference between the movement of the ejector rod 12 and the ejector part 11.

[0108] In some implementations, such as Figures 9-10 As shown, the driving component 31 includes a connecting block 313 and two connecting posts 314 protruding from the connecting block 313. Two first sliding grooves 311 are formed on the side of the connecting block 313 opposite to the connecting posts 314, and the arrangement direction of the two connecting posts 314 is consistent with the arrangement direction of the two first sliding grooves 311. In this embodiment, the driving component 31 is used to drive the ejector 11 to move up and down and horizontally. The two connecting posts 314 can ensure the consistency of the movement of the two first sliding grooves 311 and prevent the driving component 31 from tilting.

[0109] Further reference Figure 6 , Figure 7 and Figure 12 As shown, the first driving part 3 includes a first driving plate 32, and the second driving part 7 includes a second driving plate 71. The second driving plate 71 has two second clearance holes 711 corresponding to the two connecting posts 314. The second clearance holes 711 penetrate the second driving plate 71, and the fixed end 122 is connected to the second driving plate 71. The first driving plate 32 is located on the side of the second driving plate 71 away from the mold core 2. The connecting posts 314 pass through the corresponding second clearance holes 711 and are fixedly connected to the second driving plate 71. In this embodiment, the first driving plate 32 is used to drive the ejector 11 to move via the driving member 31, and the second driving plate 71 is used to drive the ejector rod 12 to move. Simultaneously, by placing the first driving plate 32 at the bottom of the second driving plate 71, after the workpiece 6 is ejected by the ejector part 1, the second driving plate 71 can easily lift the ejector rod 12 a second time, allowing the end of the ejector rod 12 to extend above the ejector 11.

[0110] In some implementations, such as Figure 1 and Figure 6As shown, the first molding assembly 5 includes multiple molding units arranged in an array. Each molding unit includes a mold core 2 and an ejector portion 1. Multiple driving members 31 are present, each corresponding to one of the molding units. The second driving plate 71 has multiple pairs of second clearance holes 711. Each pair of two second clearance holes 711 is used to avoid two connecting posts 314 of the same driving member 31. The fixed end 122 of each molding unit is simultaneously connected to the second driving plate 71, and the connecting posts 314 of each molding unit are simultaneously connected to the first driving plate 32. Therefore, the molding die can process multiple workpieces 6 simultaneously, improving the processing efficiency of the molding die.

[0111] In some implementations, such as Figure 6 , Figure 7 and Figure 12 As shown, the second drive unit 7 also includes a third drive plate 72, which has second clearance holes 711. The plurality of second clearance holes 711 on the third drive plate 72 correspond one-to-one with the plurality of second clearance holes 711 on the second drive plate 71. The second drive plate 71 and the third drive plate 72 are stacked and fixedly connected, with the fixing end 122 fixed between the second drive plate 71 and the third drive plate 72. The connecting post 314 passes sequentially through the second clearance holes 711 of the second drive plate 71 and the third drive plate 72 and connects to the first drive plate 32.

[0112] Specifically, such as Figure 7 and Figure 12 As shown, a fourth clearance hole 712 is formed between each pair of second clearance holes 711, and a clearance groove 713 is provided at the end of the fourth clearance hole 712 facing the third drive plate 72. The fixed end 122 can be clamped between the clearance groove 713 and the third drive plate 72, and the push rod 12 passes through the clearance groove 713 sequentially through the fourth clearance hole 712 and the first clearance hole 312. In this embodiment, the second drive plate 71 and the third drive plate 72 are fixedly connected, which can drive multiple push rods 12 to move synchronously.

[0113] In some implementations, such as Figure 6 and Figure 13 As shown, the molding die also includes a position adjustment part 8. The position adjustment part 8 includes a first elastic element 83, a synchronization block 81, and an adjustment rod 82. The synchronization block 81 includes a mating surface 811. One end of the first elastic element 83 abuts against the synchronization block 81. One end of the adjustment rod 82 has a guide slope 821 corresponding to the mating surface 811. The side of the guide slope 821 near the first drive plate 32 is inclined away from the synchronization block 81.

[0114] Further reference Figures 14-16 As shown, the third drive plate 72 has a first travel stroke and a second travel stroke. During the first travel stroke (e.g....) Figure 14 and Figure 17As shown, the first drive plate 32 moves upward 7mm synchronously with the second drive plate 71 along the axial direction of the ejector rod 12 via the synchronization block 81. In this configuration, the synchronization block 81 can synchronize the movement of the first drive plate 32 with the second drive plate 71 and the third drive plate 72, so that the ejector 11 and the ejector rod 12 can move upward synchronously, and the ejector part 1 lifts the workpiece 6 from the forming area 21.

[0115] During the second stroke (e.g.) Figures 15-16 As shown), the second drive plate 71 and the third drive plate 72 continue to drive the top rod 12 upward by 3mm. That is, the total stroke of the second drive part 7 is 10mm. The guide slope 821 pushes the synchronizing block 81 to separate from the first drive plate 32 through the mating surface 811, and the third drive plate 72 separates from the first drive plate 32 (distance L1), and the first elastic member 83 undergoes elastic deformation. During this process, the adjusting rod 82 can move the synchronizing block 81 so that the synchronizing block 81 is no longer in contact with the first drive plate 32, and the first drive plate 32 no longer follows the third drive plate 72 to continue moving upward. The first elastic member 83 is used to drive the synchronizing block 81 to reset. Optionally, as Figure 6 and Figure 13 As shown, the first elastic element 83 is a compression spring. One end of the compression spring abuts against the side of the synchronizing block 81 away from the first driving plate 32, and the other end abuts against the stop block.

[0116] In some implementations, such as Figures 14-16 As shown, the position adjustment unit 8 also includes a second elastic member 84, which abuts against the first drive plate 32 and the third drive plate 72. The synchronization block 81 includes a locking platform 812 and a guide wing 813, which protrude from the side of the synchronization block 81. Further referencing... Figures 6-12 As shown, a second slide groove 721 is formed on the opposite side of the third drive plate 72 and the second drive plate 71. For example, the second slide groove 721 is disposed on the third drive plate 72, such that the second slide groove 721 faces the second drive plate 71.

[0117] In the first stroke (e.g.) Figure 14 As shown), the guide ramp 821 pushes the synchronizing block 81 away from the first drive plate 32, and the edge of the first drive plate 32 rests on the mounting plate 812. The guide wing 813 extends into the second slide groove 721 and slides along the second slide groove 721, causing the first elastic member 83 to undergo elastic deformation. During the second movement stroke (as shown), the guide ramp 821 pushes the synchronizing block 81 to move away from the first drive plate 32, and the edge of the first drive plate 32 rests on the mounting plate 812. The guide wing 813 extends into the second slide groove 721 and slides along the second slide groove 721, causing the first elastic member 83 to undergo elastic deformation. Figures 15-16 As shown, the card platform 812 separates from the first drive plate 32, and the second elastic member 84 extends and deforms, causing the third drive plate 72 to separate from the first drive plate 32.

[0118] Specifically, there are two position adjustment parts 8, located on opposite sides of the first drive plate 32. The edge of the first drive plate 32 is provided with a positioning edge, the thickness of which is relatively thin. Fifth clearance holes 722 are provided on the second drive plate 71 and the third drive plate 72 (e.g., ...). Figure 7 and Figure 13 As shown, the adjusting rod 82 passes through the two fifth clearance holes 722 in sequence and then abuts against the synchronizing block 81. The third drive plate 72 may be provided with a receiving hole for accommodating the second elastic member 84, so that the second elastic member 84 can be clamped between the third drive plate 72 and the first drive plate 32. The second elastic member 84 can be a compression spring. When the second drive plate 71 is in the initial position, the mating surface 811 and the guide inclined surface 821 remain in contact, and the first elastic member 83 undergoes elastic deformation. This ensures that the first drive plate 32 can be mounted on the two synchronizing blocks 81 through the two positioning edges. As the first drive part 3 and the third drive plate 72 gradually move upward, the clamping table 812 can still maintain the limit on the first drive plate 32 within the first movement stroke. When the clamping table 812 is completely separated from the first drive plate 32, the second elastic member 84 can press down on the first drive plate 32 to ensure that the first drive plate 32 will not continue to move upward and to prevent the first drive plate 32 from sticking to the third drive plate 72. At the same time, the height difference between the end of the push rod 12 and the molding block 112 was further increased.

[0119] In some implementations, such as Figures 12-13 As shown, the first drive plate 32 has a third clearance hole 321. The second drive unit 7 also includes a drive shaft 73, which includes a second connecting end 731 and a third connecting end 732. The second connecting end 731 passes through the third clearance hole 321 and connects to the third drive plate 72, while the third connecting end 732 faces downwards from the first drive plate 32. The drive device can drive the drive shaft 73 upwards through the third connecting end 732.

[0120] Specifically, such as Figure 13 As shown, the drive shaft 73 includes a connecting bolt and a sleeve. The tail of the connecting bolt is threaded to the third drive plate 72, and the head of the connecting bolt abuts one end of the sleeve against the third drive plate 72. During the second stroke, the sleeve can pass through the third clearance hole 321 to lift the third drive plate 72, thereby separating the third drive plate 72 from the first drive plate 32.

[0121] In some implementations, such as Figure 7 , Figures 12-13As shown, the first drive plate 32 has a sixth clearance hole 322. The position adjustment part 8 also includes a limiting member 85. The limiting member 85 includes a connecting rod 851 and a limiting block 852. One end of the connecting rod 851 is connected to the limiting block 852, and the other end passes through the sixth clearance hole 322 and is connected to the third drive plate 72. During the second movement stroke, the sixth clearance hole 322 slides along the connecting rod 851 toward the limiting block 852 until the first drive plate 32 abuts against the limiting block 852.

[0122] Specifically, the limiting member 85 is a limiting screw, and there are four of them. The tail of the limiting screw is threaded to the third drive plate 72. The middle part of the limiting screw passes through the first drive plate 32, and the head of the limiting screw is used to abut against the bottom surface of the first drive plate 32, so that the first drive plate 32 can be hung on the four limiting screws during the second movement stroke.

[0123] It is easy to understand that when the clamping table 812 separates from the first drive plate 32, the first drive plate 32 will move downward under the action of the second elastic element 84. If the first drive plate 32 is not further restrained, the molding block 112 will fall into the receiving groove 24, which may cause the molding surface 1121 to touch the workpiece 6 again. On the other hand, the first drive plate 32 will slide back to its initial position, which is also not conducive to the reset of the molding mold.

[0124] Therefore, after the card table 812 separates from the positioning edge, the first drive plate 32 is lifted by the limiting block 852, thereby limiting the position of the ejector 11 and the position of the first drive plate 32.

[0125] In some implementations, such as Figure 13 As shown, the first molding assembly 5 further includes a first mold base 91, a second mold base 92, and a spacer block 93. The spacer block 93 is disposed between the first mold base 91 and the second mold base 92, such that the first mold base 91 and the second mold base 92 are spaced apart by a predetermined distance. The end of the adjusting rod 82 away from the first drive plate 32 is connected to the first mold base 91. The first drive plate 32, the second drive plate 71, and the third drive plate 72 are disposed between the first mold base 91 and the second mold base 92. A third elastic element may also be disposed between the first mold base 91 and the second drive plate 71, so that the second drive plate 71 and the third drive plate 72 can be reset in a timely manner.

[0126] In some implementations, such as Figures 12-13As shown, the position adjustment unit 8 also includes a first limiting post 86 and a second limiting post 87. One end of the first limiting post 86 is connected to the first drive plate 32, and the other end passes through the seventh clearance hole of the second drive plate 71 and the third drive plate 72, extending towards the first mold base 91. One end of the second limiting post 87 is connected to the top surface of the second drive plate 71, and the other end extends towards the first mold base 91. The distance from the first limiting post 86 to the first mold base 91 is less than the distance from the second limiting post 87 to the first mold base 91. The distance from the second limiting post 87 to the first mold base 91 is 10mm. At the beginning of the second movement stroke, the first limiting post 86 abuts against the bottom of the first mold base 91, and at the end of the second movement stroke, the second limiting post 87 abuts against the first mold base 91.

[0127] Therefore, at the beginning of the second movement stroke, if the second elastic element 84 suffers fatigue damage, preventing it from separating the first drive plate 32 from the third drive plate 72, the first limiting post 86 can force them to separate. When the second movement stroke ends, the second limiting post 87 can ensure the extension height of the push rod 12.

[0128] Furthermore, such as Figure 13 As shown, a pad 921 is provided on the top surface of the second mold base 92, and the pad 921 can be the head of a screw. When the molding mold is reset, the bottom surface of the first drive plate 32 will abut against the pad 921 until the first drive plate 32 abuts against the third drive plate 72 again. In this configuration, a slot is formed between the positioning edge and the pad 921, which allows the locking plate 812 to be inserted into the bottom of the positioning edge.

Various modifications and variations can be made to this utility model by those skilled in the art.
