Abstract
Description
Technical Field
[0001] This invention relates to the field of molds, and more specifically to an insert injection mold. Background Technology
[0002] As attached Figures 1-2 As shown, the existing connector includes a body 100 and two conductive plates 101. The body 100 is made of plastic. The difference between the two conductive plates 101 is that one conductive plate 101 has two tops 1011, while the other conductive plate 101 has only one top 1011. The lower part of each conductive plate 101 has a foot structure, specifically a stepped structure. The manufacturing process requires that after injection molding, the top of the connector (i.e., the top 1011 of the conductive plate 101) is exposed, and the sides of the connector have solder areas (i.e., the exposed portion of the foot 1012, specifically a rectangular area, for soldering connection).
[0003] This type of connector is manufactured using insert injection molding, which involves placing two conductive pieces 101 into a cavity, injecting colloid, and then injection molding to form a body 100 with the conductive pieces 101 fixed in place (the colloid forming the body 100). However, currently, the conductive pieces 101 are manually placed into the cavity, which presents the following problems: First, the conductive pieces 101 are not securely fixed in the cavity, causing their position to shift during the flow of the colloid; second, the support legs 1012 of the conductive pieces 101 are thin and flexible, and even if one end is fixed, the conductive pieces 101 may deform during the flow of the colloid, affecting subsequent normal use; third, processing efficiency is affected because the temperature inside the cavity is high after processing, making it impossible for workers to directly insert the conductive pieces 101. They must either wait for the temperature to drop or use auxiliary tools for placement (which presents accuracy issues), both of which affect processing efficiency. Summary of the Invention

The third drive source drives the first ejector rod to move, and the first ejector rod drives the first connecting block and the movable insert to move upward along a third direction. The gripper drives the conductive sheet to connect and fix with the movable insert, and the gripper mechanism drives the movable insert to move downward along a third direction. The second drive source drives the second slider and the inner slider core to move, the pressing member abuts against the conductive sheet, the first positioning post extends to the groove, the second drive source is activated, and a first gap is formed between the second drive source and the second slider. When the fixed mold and the moving mold are engaged, the bent pull rod drives the inner slider core to move away from the movable insert along the first direction. In the second state, the fixed mold and the moving mold are separated. The bent tie rod drives the inner slider core and the second slider to move. The first drive source drives the first slider, the first connecting block, and the movable insert to move away from the moving mold insert. The fourth drive source drives the second ejector rod to move. The second ejector rod ejects the completed connector.
[0005] The first positioning post has a stepped structure, and the first positioning post has a stepped surface, with the conductive sheet abutting against the stepped surface.
[0006] The first positioning hole and the front end of the first positioning post are interference fit, and the interference clearance is 0.01-0.05mm.
[0007] The movable insert is provided with a fixing groove, and the side of the support leg away from the top is inserted into the fixing groove for fixation.
[0008] The moving mold insert has a second positioning post on the side facing the fixed mold insert, and the top of the conductive sheet has a second positioning hole that mates with the second positioning post.

[0014] The technical solution of this invention has the following advantages: 1. This invention provides an insert injection mold with a structure that uses a gripper mechanism to feed the conductive sheet and allow the entire movable insert to enter the moving mold, forming part of the cavity for injection molding. Secondly, the abutment component enhances the stability between the conductive sheet and the movable insert, preventing positional displacement and improving injection efficiency. Furthermore, a first drive source moves the first slider, meaning the cavity facing the first drive source is driven and fixed. On the second drive source side, after pushing the second slider to its position, the second drive source resets, separating it from the second slider. The movement of the inner slider core is achieved via a bent pull rod, creating a gap between the abutment component and the conductive sheet before injection molding, which the colloid can fill. After injection molding, the second ejector rod moves to achieve ejection, allowing the finished connector to be removed using a robotic arm or other gripping methods. Compared to existing technologies, the entire process is machined, eliminating the need for manual material feeding and unloading, and eliminating the need to consider mold temperature, thus improving processing efficiency. Moreover, this mold design allows for simultaneous multi-cavity processing, greatly enhancing processing efficiency.
[0015] 2. The insert injection mold provided by this invention has the following design: the position of the conductive sheet is constant; secondly, a gap is formed between the conductive sheet and the movable insert, which can be filled with the colloid, preventing excessive exposure of the conductive sheet. Alternatively, the conductive sheet and the movable insert can be directly bonded together.

[0018] 5. The present invention provides an insert injection mold in which the cooperation of the second positioning post and the second positioning hole forms the top of the conductive sheet for fixation.
[0019] 6. The present invention provides an insert injection mold in which the bending tie rod achieves two effects: one effect is to drive the inner slider core to move while the second slider is stationary; the other effect is to drive the second slider and the inner slider core to move synchronously.

[0027] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0030] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0031] Example 1 This embodiment provides an insert injection mold, as shown in the attached figure. Figures 1-12 As shown, it includes: The moving mold insert 11 is connected and fixed to the moving mold. The moving mold insert 11 has a cavity 111, which extends horizontally along a first direction. The cavity 111 specifically mates with the outer slider core 14.
[0032] Fixed mold insert 12 is connected and fixed to the fixed mold. When the fixed mold and the moving mold are engaged, the fixed mold insert 12 and the moving mold insert 11 are in contact. In this embodiment, when the fixed mold and the moving mold are engaged, the fixed mold insert 12 is located above the moving mold insert 11.
[0033] Movable insert 13, located within the moving mold, works with moving mold insert 11 and fixed mold insert 12 to form cavity 108. This cavity 108 is for injection molding; the adhesive is injected into this cavity 108 and, after cooling, molds into a connector with conductive pieces 101. Movable insert 13 has two sets of first positioning posts 131. Since there are two conductive pieces 101, the two sets of first positioning posts 131 correspond to the two conductive pieces 101 respectively. The support structures of the conductive pieces 101 are identical, and they are arranged parallel to each other. One set of first positioning posts 131 corresponds to the first positioning hole 1013 at the bend of one of the support pieces 1012, and the other set of first positioning posts 131 corresponds to the first positioning hole 1013 at the bend of the other support piece 1012.
[0034] The first slider mechanism includes a first slider 15, a first connecting block 16, and a first driving source 17. The first connecting block 16 is connected to the movable insert 13, and the first connecting block 16 and the movable insert 13 move synchronously, meaning that when the first connecting block 16 moves, the movable insert 13 also moves accordingly. The other side of the first connecting block 16 is connected to the first slider 15, meaning that the first connecting block 16 is located between the movable insert 13 and the first slider 15, serving as a connecting and transmission function. In this embodiment, the first connecting block 16 slides relative to the first slider 15 in a third direction, specifically, the Z-axis direction. The first driving source 17 drives the first slider 15 to move along a first direction, specifically the X-axis direction. When the first driving source 17 is activated, it drives the first slider 15 to move along the X-axis. At this time, the first connecting block 16 and the movable insert 13 also move accordingly. When the first slider 15 is stationary, under the drive of other forces, the first connecting block 16 can slide relative to the first slider 15 along the Z-axis, thereby achieving synchronous sliding of the first connecting block 16 and the movable insert 13 along the Z-axis. In this embodiment, the movable insert 13 can slide along both the X-axis and Z-axis. Here, the first slider mechanism is located on the left side of the cavity 108, meaning the first slider 15 is located on the left side of the cavity 108, and the movable insert 13 cooperates to form the left side surface of the cavity 108.
[0035] The second slider mechanism includes a second slider assembly and a second drive source 18. The second drive source 18 drives the second slider assembly to move along a first direction, which is the X-axis direction. In this embodiment, the second drive source 18 is located on the right side of the cavity 108, meaning the first slider mechanism is located on the left side of the cavity 108, and the second slider mechanism is located on the right side of the cavity 108. The second slider assembly includes a second slider 19, an inner slider core 20, and an outer slider core 14. The second slider 19 and the outer slider core 14 are connected and fixed, and they move synchronously. The outer slider core 14 has a channel 141, which extends along the X-axis direction. The second slider 19 has a cavity 191, and the inner slider core 20 is housed in the cavity 191. The inner slider core 20 slides relative to the second slider 19 in the first direction. In this embodiment, the inner slider core 20 cooperates with the second drive source 18. When the second drive source 18 is working, it drives the inner slider core 20 to slide to the left along the X-axis. Then, the inner slider core 20 abuts against the inner wall of the cavity 191, causing the second slider 19 and the outer slider core 14 to move synchronously. The inner slider core 20 is fixed with a pressing member 21, which passes through the channel 141. Here, the pressing member 21 can extend out of the outer slider core 14 or return to be flush with the outer side wall of the outer slider core 14. The pressing member 21 is provided with a groove 211, which is located on the left side of the pressing member 21, that is, the side facing the cavity 108. In the actual injection molding process, the left side of the outer slider core 14 and the left side of the pressing member 21 are both part of the side wall of the cavity 108.
[0036] The first ejection mechanism includes a third drive source 22 and a first ejector rod 23. The third drive source 22 drives the first ejector rod 23 to move along a third direction and along the Z-axis. In this embodiment, the first ejector rod 23 is located below the first connecting block 16. The movement trajectory of the first ejector rod 23 intersects with the movement trajectory of the first connecting block 16. Specifically, when the first slider 15 moves to the right, sliding the movable insert 13 to the right to the side wall of the cavity 108 (at this time, the right side of the movable insert 13 is the side wall of the cavity 108), the first connecting block 16 is located on the movement trajectory of the first ejector rod 23. That is, at this time, the first ejector rod 23 moves upward along the Z-axis, and the first ejector rod 23 drives the first connecting block 16 to move upward along the Z-axis. The movable insert 13 also moves upward along the Z-axis simultaneously.
[0037] The second ejection mechanism includes a fourth drive source 24 and a second ejector rod 25. The fourth drive source 24 drives the second ejector rod 25 to move along a third direction. Here, the second ejector rod 25 is a discharge ejector rod, which means that after injection molding is completed, the second ejector rod 25 can eject the injection-molded connector.
[0038] The bending tie rod mechanism includes a bending tie rod 26, which is connected to the fixed mold. The attached drawings do not show how the bending tie rod 26 is connected to the fixed mold, but this is prior art, and those skilled in the art should understand the connection relationship between the two.
[0039] The gripper mechanism includes a gripper 27, which drives the conductive sheet 101 to move. Here, the gripper 27 drives two conductive sheets 101 to move simultaneously, thus creating a feeding effect.
[0040] In the first state, after mold opening, the conductive sheet 101 is installed. The first drive source 17 drives the first slider 15 to slide to the right. The first slider 15 drives the first connecting block 16 and the movable insert 13 to slide towards the moving mold insert 11. At this time, the movable insert 13 is in its final position, and its right side is the sidewall of the cavity 108. The third drive source 22 drives the first ejector 23 to move upward along the Z-axis. The first ejector 23 drives the first connecting block 16 and the movable insert 13 to move upward along the Z-axis. At this time, the first connecting block 16 and the movable insert 13 both extend beyond the top surface of the moving mold, and the right side of the movable insert 13 is exposed. The gripper 27 drives the conductive sheet 101 to connect and fix with the movable insert 13. Here, the gripper 27 moves from the right side of the movable insert 13 towards its right side surface, thereby achieving the connection and fixation effect between the conductive sheet 101 and the movable insert 13. Specifically, the first positioning hole 1013 cooperates with the first positioning post 131 to achieve the positioning and fixing effect. After the conductive sheet 101 is fixed, the gripper mechanism drives the movable insert 13 to move downward along the third axis. Here, the gripper mechanism abuts against the first connecting block 16, driving the first connecting block 16 to move downward along the Z-axis, so that the movable insert 13 moves into place. At this time, the right side surface of the movable insert 13 is the side wall of the cavity 108. It should also be noted that after the conductive sheet 101 is loaded, the gripper mechanism moves out from above the moving mold to make way, without interfering with the movement of the fixed mold. The above steps make the left side of the cavity 108 fixed. The second drive source 18 drives the second slider 19 and the inner slider core 20 to move. Specifically, the second drive source 18 drives the inner slider core 20 to move to the left. The inner slider core 20 abuts against the side of the cavity 191, causing the second slider 19 and the outer slider core 14 to move together to the left until the pressing member 21 abuts against the conductive sheet 101, so that the conductive sheet 101 is better connected and fixed to the movable insert 13. At this time, the first positioning post 131 extends to the groove 211 and can abut against the groove 211. There can also be a gap between the first positioning post 131 and the groove 211. When the second drive source 18 is activated, the second drive source 18 resets, and a first gap is formed between the second drive source 18 and the second slider 19. The first gap refers to the gap between the second drive rod 181 of the second drive source 18 and the second slider 19. When the second drive source 18 resets, the second drive rod 181 and the second slider 19 are separated and do not contact each other.When the fixed mold and the moving mold are engaged, the bent tie rod 26 drives the inner slider core 20 to move along the first direction away from the movable insert 13. Here, the bent tie rod 26 drives the inner slider to move to the right. At this time, the second slider 19 and the outer slider core 14 are in a fixed state, and only the inner slider core 20 moves. At the same time, the pressing part 21 also moves to the right, and the pressing part 21 and the conductive sheet 101 no longer press against each other. A gap is formed between the pressing part 21 and the conductive sheet 101. This gap is used for filling with colloid, and finally the body 100 is formed. After the fixed mold and the moving mold are completed, the cavity 108 is assembled. The injection molding process is realized by injecting colloid through potting.
[0041] The second state refers to the state after processing, that is, after injection molding is completed, and the material is being removed. First, the fixed mold and the moving mold separate. The bent tie rod 26 drives the inner slider core 20 and the second slider 19 to move. The inner slider core 20, the second slider 19, and the outer slider core 14 move synchronously to the right. The first drive source 17 drives the first slider 15, the first connecting block 16, and the movable insert 13 to move away from the moving mold insert 11. The first slider 15, the first connecting block 16, and the movable insert 13 move to the left, realizing the opening operation of the cavity 108. Finally, the fourth drive source 24 drives the second ejector rod 25 to move. The second ejector rod 25 moves upward along the Z-axis and ejects the processed connector. With this structural design, the conductive sheet 101 is fed into the moving mold via a gripper mechanism, and the entire movable insert 13 enters the moving mold to form part of the cavity 108 for injection molding. Secondly, the abutment 21 abuts against the conductive sheet 101, improving the stability of the connection between the conductive sheet 101 and the movable insert 13, preventing displacement of the conductive sheet 101 and improving injection molding efficiency. Furthermore, the first drive source 17 drives the first slider 15 to move; that is, the cavity 108 facing the first drive source 17 is driven and fixed by the first drive source 17. On the second drive source 18 side, after pushing the second slider 19 to its position, the second drive source 18 resets. At this time, the second drive source 18 and the second slider 19 are separated. The movement of the inner slider core 20 is achieved through the bent pull rod 26, creating a gap between the abutment 21 and the conductive sheet 101 before injection molding, which the colloid can fill. After injection molding, the second ejector rod 25 moves to achieve the ejection effect. At this point, a robotic arm or other gripping method can be used to remove the finished connector. Compared to existing technologies, the entire process is machined, eliminating the need for manual material feeding and unloading, and eliminating the need to consider mold temperature, thus improving processing efficiency. Moreover, this mold design allows for simultaneous multi-cavity processing, greatly enhancing processing efficiency.
[0042] Specifically, as shown in the attached document Figures 8-9As shown, the first positioning post 131 has a stepped structure. Specifically, the stepped structure refers to multiple posts with different cross-sectional dimensions working together to form a stepped structure. In this embodiment, the first positioning post 131 includes two posts extending to the right. The cross-sectional dimension of the post at the rightmost end is smaller than that of the other post, and the connection between the two forms a stepped surface 1311. When the first positioning hole 1013 engages with the first positioning post 131, the conductive sheet 101 abuts against the stepped surface 1311. Specifically, the support leg 1012 of the conductive sheet 101 abuts against the stepped surface 1311. This arrangement ensures that the position of the conductive sheet 101 remains constant. Furthermore, a gap is formed between the conductive sheet 101 and the movable insert 13, which can be filled with adhesive to prevent excessive exposure of the conductive sheet 101. Alternatively, the conductive sheet 101 can be directly attached to the movable insert 13.
[0043] Specifically, the first positioning hole 1013 and the front end of the first positioning post 131 are interference-fitted. The front end of the first positioning post 131, which is the rightmost post, has an interference gap of 0.01-0.05mm, meaning the diameter of the rightmost post is larger than the inner diameter of the first positioning hole 1013, thus forming an interference fit. This interference fit further improves the tightness of the fit between the conductive sheet 101 and the movable insert 13, preventing the colloid from affecting the position of the conductive sheet 101 during flow.
[0044] Specifically, as shown in the attached document Figures 8-9 As shown, the movable insert 13 has a fixing groove 132, and the side of the support leg 1012 away from the top 1011 is inserted into the fixing groove 132 for fixation. The fixing groove 132 provides a multi-point fixing effect. This creates at least three points of positioning and fixing, improving the firmness and stability of the conductive sheet 101. The distance between the inner wall of the fixing groove 132 and the outer wall of the support leg 1012 is 0.01-0.03 mm.
[0045] Specifically, as shown in the attached document Figures 3-12As shown, a second positioning post 112 is provided on the side of the moving mold insert 11 facing the fixed mold insert 12. Here, the second positioning post 112 extends upward along the Z-axis. The top 1011 of the conductive sheet 101 has a second positioning hole 1014 that mates with the second positioning post 112. When the conductive sheet 101 is fixed to the moving insert 13, the gripper mechanism drives the moving insert 13 to move downward along the Z-axis. At this time, the second positioning post 112 mates with the second positioning hole 1014, achieving the effect of positioning and fixing the top 1011 of the conductive sheet 101. The distance between the outer wall of the second positioning post 112 and the inner wall of the second positioning hole 1014 is 0.01-0.03 mm. In this embodiment, there are six second positioning posts 112, divided into three groups, corresponding to three tops 1011, each top 1011 having two second positioning holes 1014. Alternatively, those skilled in the art can select an appropriate number according to actual needs. The second positioning post 112 and the second positioning hole 1014 cooperate to fix the top 1011 of the conductive sheet 101.
[0046] Specifically, as shown in the attached document Figures 1-12 As shown, in this embodiment, the support leg 1012 has two bending areas. Taking a conductive sheet 101 with a top 1011 as an example, its top 1011 is positioned and fixed by the second positioning post 112 and the second positioning hole 1014. Each of the two bending areas has a first positioning hole 1013. Correspondingly, the movable insert 13 also has a corresponding number of first positioning posts 131. At this time, two positioning and fixing points are formed. The lowermost end of the support leg 1012 (that is, the side of the support leg 1012 away from the top 1011) is connected and fixed to the fixing groove 132, forming a downward fixing effect. Specifically, a conductive sheet 101 forms four fixing points. The uppermost, lowermost, and middle fixing points are interference fits, and the four fixing points are located in different spatial positions, which can better achieve the positioning and fixing effect of the conductive sheet 101 and prevent the conductive sheet 101 from shaking or displacing during the injection molding process.
[0047] Specifically, the two sets of first positioning posts 131 are set in parallel, and their positions and heights are the same.
[0048] Specifically, as shown in the attached document Figures 11-12 As shown, there are two pressing members 21. When there are two first positioning posts 131 in a set, the two first positioning posts 131 are arranged vertically and horizontally. At this time, one pressing member 21 cooperates with the two first positioning posts 131 located above, and the other pressing member 21 cooperates with the two first positioning posts 131 located below.
[0049] Specifically, as shown in the attached document Figures 11-12As shown, the bent pull rod 26 includes a first oblique cut portion 261 and a second oblique cut portion 262. The first oblique cut portion 261 engages with a first mating portion 201 disposed on the inner slider core 20. When the first oblique cut portion 261 engages with the first mating portion 201, the bent pull rod 26 drives the inner slider core 20 to move, specifically driving the inner slider core 20 to move to the right. In this embodiment, the first oblique cut portion 261 and the first mating portion 201 are specifically obliquely mated, that is, obliquely planed, to decompose the vertical force into a partial force directed to the right. (See attached diagram) Figure 11-12 As shown, a gap is formed between the inner slider core 20 and the outer slider core 14. The second oblique cut portion 262 engages with the second mating portion 192 disposed on the second slider 19. When the second oblique cut portion 262 abuts against the second mating portion 192, the bent pull rod 26 drives the second slider 19 to move to the right. In this embodiment, the second oblique cut portion 262 and the second mating portion 192 are specifically obliquely mated, that is, obliquely oriented, which decomposes the vertical force into a partial force to the right. The bent pull rod 26 achieves two effects: one effect is to drive the inner slider core 20 to move, at which time the second slider 19 is stationary; the other effect is to drive the second slider 19 and the inner slider core 20 to move synchronously. One cavity 108 corresponds to one bent pull rod 26. When the entire mold has four cavities 108, the number of bent pull rods 26 is four.
[0050] Specifically, one first slider 15 can cooperate with two first connecting parts, that is, the two cavities 108 only need to be equipped with one first driving source 17 and one first slider 15.
[0051] Specifically, as shown in the attached document Figures 11-12 As shown, the second slider 19 and the outer slider core 14 are connected and fixed, and the two move synchronously. The inner slider core 20 can slide relative to the second slider 19 and the outer slider core 14 in the first direction, that is, on the X-axis. It should be noted that the sliding range here corresponds to the gap between the pressing member 21 and the conductive sheet 101, and is not an infinite sliding. The gap between the pressing member 21 and the conductive sheet 101 is the distance that the bent pull rod 26 controls the sliding of the inner slider core 20. For example, if the bent pull rod 26 drives the inner slider core 20 to move 1mm, the gap between the pressing member 21 and the conductive sheet 101 is 1mm. Those skilled in the art can adjust the distance that the bent pull rod 26 drives the inner slider core 20 to move according to actual needs.
[0052] Specifically, as shown in the attached document Figures 11-12As shown, the second slider 19 is fixed with a limiting component 28, which restricts the bending tie rod 26 from shifting. The limiting component 28 guides and limits the bending tie rod 26, preventing it from shifting. The limiting component 28 includes two limiting rods 281, which are arranged opposite to each other. The limiting rods 281 extend into the cavity 191, and the bending tie rod 26 passes into the cavity 191. The second oblique cut portion 262 also passes into the cavity 191. Because it is obliquely arranged, the limiting rods 281 limit the movement.
[0053] Specifically, a clearance structure is provided between the pressing member 21 and the second push rod 25. This clearance structure includes a groove 212 disposed on the pressing member 21, through which the second push rod 25 passes, and the second push rod 25 slides relative to the groove 212 in a first direction. This clearance structure creates a misalignment between the second push rod 25 and the pressing member 21, preventing interference and improving the discharge efficiency. The length of the groove 212 can be adjusted according to actual needs.
[0054] Specifically, as shown in the attached document Figures 8-9 As shown, the movable insert 13 includes a main body 133 and an insert 134, which are fixed together by a pin connection. The pin 135 passes through the main body 133 and the insert 134, and finally exits from the rear side of the main body 133. The insert 134 is separate from the main body 133, allowing for adjustment according to actual needs. Simultaneously, the first positioning post 131 can be mounted on the insert 134. An interference fit will cause wear on the first positioning post 131. Excessive machining can affect its service life. In this case, the insert 134 can be replaced to ensure the interference fit and improve the stability of the conductive sheet 101.
[0055] Specifically, as shown in the attached document Figures 3-7 As shown, one of the first slider 15 and the first connecting block 16 is provided with a guide groove 29, and the other of the first slider 15 and the first connecting block 16 is provided with a guide protrusion 30 that cooperates with the guide groove 29. The arrangement of the guide groove 29 and the guide protrusion 30 creates a guiding sliding effect. When the first slider 15 is provided with the guide groove 29, the first connecting block 16 is provided with the guide protrusion 30; conversely, when the first slider 15 is provided with the wire protrusion, the first connecting block 16 is provided with the guide groove 29.
[0056] Specifically, a mold can be used to form four or eight cavities 108.
[0057] Specifically, as shown in the attached document Figures 3-7 As shown, the gripper mechanism can be used in multi-axis robots, or it can be composed of multiple drive mechanisms working together to achieve movement in multiple directions, including the X, Y, and Z axes. (See attached image) Figure 4As shown, the gripper mechanism is a movable platform structure. When loading is required, the gripper mechanism moves above the moving mold, and the gripper 27 clamps the conductive sheet 101. It moves from the right side of the movable insert 13 towards the movable insert 13 until the first positioning pin 131 engages with the first positioning hole 1013, and the lower end of the support leg 1012 engages with the fixing groove 132, achieving a side-fixing effect for the conductive sheet 101. Then, the gripper mechanism also includes a push plate 31, which moves along the Z-axis and pushes downwards along the Z-axis. The push plate 31 abuts against the first connecting block 16, causing the first connecting block 16 and the movable insert 13 to move downwards until the second positioning pin 112 engages with the second positioning hole 1014, achieving a fixing effect for the conductive sheet 101. It should be noted that during this operation, the first push rod 23 and the push plate 31 cooperate with each other, and the first push rod 23 is also in a retracted working state, so the first push rod 23 does not restrict the downward movement of the push plate 31. Once the movable insert 13 has moved into position, the gripper mechanism moves to the outside and will not interfere with the movement of the fixed mold.
[0058] Specifically, the driving source in this embodiment (including the first driving source, the second driving source, the third driving source, and the fourth driving source) can be a cylinder, a hydraulic cylinder, or a motor, which can be adjusted by those skilled in the art according to actual needs.
[0059] Specifically, it also includes a control mechanism, which controls the operation of each mechanism. This control mechanism can be PLC control or other control methods.
[0060] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
