Description

Technical Field

[0001] This utility model relates to the field of external embedded marking technology, specifically to an insert forming mold with shearing function and an external embedded marking device. Background Technology

[0002] With the rapid development of the new energy industry, the demand for power batteries continues to increase. To ensure safety, the battery casing needs to be equipped with explosion-proof grooves or explosion-proof sheets to release pressure when the internal pressure is too high.

[0003] Existing marking methods generally include the following: stamping forming principle, which uses the cooperation of upper and lower stamping dies to apply pressure to the battery casing to form explosion-proof markings; laser etching principle, which uses a laser to directly etch the outer or inner surface of the battery casing to form explosion-proof markings; and step-by-step stamping processing principle, which uses a step-by-step approach for marking explosion-proof diaphragms, first processing shallow marks, and then stamping explosion-proof markings on the basis of shallow marks.

[0004] While the aforementioned scoring method can achieve pressure relief, during normal battery use, the scored area is relatively thin, making it prone to failure and premature explosion when the battery casing is deformed by external forces. Furthermore, traditional insert processing may require multiple independent steps and equipment, resulting in a complex production process, low efficiency, and high cost.

[0005] Externally embedded scoring products can create weak pressure relief areas on the battery casing while simultaneously supporting these areas with externally embedded inserts, thus reducing the risk of failure. Currently, neither the insert forming molds nor the externally embedded scoring equipment are available on the market. Utility Model Content

[0006] In view of this, the present invention provides an insert forming mold with shearing function and an external embedded scoring device, which aims to solve the above-mentioned technical problems.

[0007] This utility model discloses a strip forming mold with a shearing function, comprising a lower mold and an upper mold located above the lower mold. The upper mold includes a lifting strip forming plate, a strip ejection drive assembly, and a strip cutting assembly located above the lower mold. The lifting strip forming plate has a strip forming groove with one end closed for the strip to extend into. The lower mold has a contour groove corresponding to the strip forming groove. At least a portion of the strip cutting assembly is disposed on the lifting strip forming plate, and the remaining portion is disposed on the strip ejection drive assembly. The strip ejection drive assembly includes a strip ejection part that extends at least partially into the strip forming groove. When the strip ejection drive assembly moves downward relative to the lifting strip forming plate, the strip cutting assembly cuts the strip, and the strip ejection part pushes the cut strip into the contour groove.

[0008] Preferably, the stripping drive assembly includes a fixed plate and a second linear driver. The stripping part is fixed to the fixed plate, and the second linear driver drives the fixed plate and causes the stripping part to extend into the insert forming groove.

[0009] Preferably, the stripping drive assembly further includes a stripping back plate disposed between the fixed plate and the lifting insert forming plate, and the stripping back plate is provided with a clearance hole for the stripping part to pass through.

[0010] Preferably, the insert strip cutting assembly includes a cutting groove disposed on the lifting insert forming plate and communicating with the insert forming groove, a cutting insert block in the cutting groove, and a cutting blade disposed on the fixed plate; at least a portion of the cutting blade extends into the cutting groove and the cutting insert block is driven to move in the cutting groove through a beveled engagement structure.

[0011] Preferably, the upper mold further includes an upper template and an elastic element one; the fixed plate is located in the space between the upper template and the stripping back plate; one end of the elastic element one acts on the upper template, and the other end of the elastic element one passes through the fixed plate and acts on the stripping back plate; the linear actuator two is fixed to the upper template and the driving end of the linear actuator two is connected to the fixed plate; the upper template is connected to the driving end of the linear actuator one.

[0012] Preferably, the upper mold and the lower mold are movably connected by a guide component, at least a portion of the guide component is disposed on the upper mold, and the remaining portion of the guide component is disposed on the lower mold.

[0013] Preferably, the insert forming groove is provided with a stripping insert, and an elastic element is provided between the strip forming groove and the strip forming groove.

[0016] Compared with existing technologies, the advantages of this invention lie in the fact that the upper mold is equipped with a lifting insert forming plate, a stripping drive assembly, and an insert shearing assembly. Multiple processes, including insert forming, shearing, and strip removal, are completed within the upper mold structure, achieving integrated production. Traditional insert processing may require multiple independent processes and equipment, resulting in a complex production process, low efficiency, and high cost. This invention's mold, by integrating multiple functions, solves the problems of numerous intermediate steps and low efficiency in traditional processes, making it suitable for industrial scenarios requiring continuous and efficient insert production.

[0021] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0022] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this application.

[0023] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0024] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" 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 between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] Example 1, combined with Figure 1 , Figure 3 , Figure 7 As shown, this embodiment provides an insert forming mold with a shearing function, including a lower mold 2 and an upper mold 1 located above the lower mold 2. The upper mold 1 includes a lifting insert forming plate 11 located above the lower mold 2, a stripping drive assembly, and an insert cutting assembly. The lifting insert forming plate 11 has an insert forming groove 111 with one end closed for the insert 3 to extend into. The lower mold 2 has a contoured groove 21 corresponding to the insert forming groove 111. At least a portion of the insert cutting assembly is disposed on the lifting insert forming plate 11, and the remaining portion is disposed on the stripping drive assembly. The stripping drive assembly includes a stripping part 131 that extends at least partially into the insert forming groove 111. When the stripping drive assembly moves downward relative to the lifting insert forming plate 11, the insert cutting assembly cuts the insert 3, and the stripping part 131 pushes the cut insert into the contoured groove 21.

[0026] Specifically, in this embodiment, the embedded strip 3 refers to continuous strip material, and the embedded strip refers to short material after shearing.

[0027] Specifically, by setting a lifting insert forming plate 11, a stripping drive assembly, and an insert shearing assembly in the upper mold 1, the integrated production operation of insert forming, shearing, and strip removal can be completed within the upper mold 1 alone. After the insert 3 is fed into the insert forming groove 111 of the upper mold 1, the lifting insert forming plate 11 of the upper mold 1 moves downward under the drive of the strip removal drive assembly. The insert shearing assembly cuts the insert 3 into inserts, and at the same time, the strip removal part 131 pushes the cut inserts into the contour groove 21 of the lower mold 2. The entire process realizes the integration of forming, shearing, and strip removal, reducing intermediate steps and improving production efficiency. In a multi-station production line, multiple lower molds 2 can be set up. Only the lower mold 2 needs to be changed to achieve continuous operation of the insert 3, improving production efficiency and reducing mold production costs.

[0028] Preferred, combined Figure 1 , Figure 3 , Figures 5 to 7As shown, the stripping drive assembly includes a fixed plate 13 and a linear actuator 142. The stripping part 131 is fixed to the fixed plate 13, and the linear actuator 142 drives the fixed plate 13 and causes the stripping part 131 to extend into the insert forming groove 111. A stripping insert 112 is provided in the insert forming groove 111, and an elastic member 113 is provided between the stripping insert 112 and the insert forming groove 111.

[0029] Specifically, the linear actuator 142 provides power to the fixed plate 13, causing the fixed plate 13 to drive the stripping part 131 to move linearly. When the fixed plate 13 approaches the lifting insert forming plate 11, at least a portion of the strip forming part 131 extends into the strip forming groove 111 and abuts against the stripping insert 112. The fixed plate 13 continues to approach the lifting insert forming plate 11, and the strip obtained after being sheared by the stripping insert 112 falls into the contour groove 21.

[0030] Specifically, the stripping insert 112 is provided with a reset connection part. The reset connection part moves with the stripping insert 112 in the insert forming groove 111. The reset connection part is connected to the bottom of the insert forming groove 111 through the elastic member 2 113. This allows the insert obtained after being pushed and sheared by the stripping insert 112 to fall into the contour groove 21. The elastic member 2 113 can automatically reset the strip, providing a space for the insert strip 3 to re-enter the insert forming groove 111 for forming and shearing.

[0031] Understandably, the linear actuator 142 provides precise and stable linear motion power, the stripping part 131 directly contacts the stripping insert 112 to achieve stripping, and the stripping insert 112 achieves automatic reset through the energy storage and reset characteristics of the elastic element 113, thus realizing the automation and efficiency of the stripping process.

[0032] Preferred, combined Figure 4 As shown, the stripping drive assembly also includes a stripping back plate 12 disposed between the fixed plate 13 and the lifting insert forming plate 11, and the stripping back plate 12 is provided with a clearance hole 121 for the stripping part 131 to pass through.

[0033] Specifically, a stripping back plate 12 is provided between the fixed plate 13 and the lifting insert forming plate 11. The stripping back plate 12 makes one side of the lifting insert forming groove 111 closed, ensuring that the position of the stripping insert 112 and the insert is relatively stable, thereby improving the accuracy of mold production.

[0034] Preferred, combined Figure 3 , Figure 5 , Figure 7As shown, the insert strip cutting assembly includes a cutting groove 114 disposed on the lifting insert forming plate 11 and communicating with the insert forming groove 111, a cutting insert block 115 in the cutting groove 114, and a cutting blade 132 disposed on the fixing plate 13; at least a portion of the cutting blade 132 extends into the cutting groove 114 and drives the cutting insert block 115 to move in the cutting groove 114 through the inclined surface mating structure.

[0035] Because a spring element 116 is provided between the side of the shearing block 115 away from the insert 132 and the shearing groove 114, when the insert 132 is not inserted into the shearing groove 114, the spring element 116 is in an extended state, and the side of the shearing block 115 near the shearing groove 114 where the spring element 116 is not provided; when the insert 132 is inserted into the shearing groove 114, the inclined surface fit structure causes the axial movement of the insert 132 to be converted into the lateral movement of the shearing block 115 along the shearing groove 114, thereby shearing the embedded strip 3. At the same time, the lateral movement of the shearing block 115 will compress the spring element 116, and when the insert 132 leaves the shearing groove 114, the spring element 116 pushes the shearing block 115 to reset.

[0036] Preferred, combined Figure 5 As shown, the embedded strip cutting assembly also includes an embedded strip guide block 117 that is at least partially embedded in the lifting embedded strip forming plate 11; the embedded strip guide block 117, at least part of the lifting embedded strip forming plate 11, and the cutting block 115 are provided with a communicating embedded strip guide groove 1171, and the embedded strip guide groove 1171 is communicating with the embedded strip forming groove 111.

[0037] Specifically, the insert strip 3 extends into the insert strip forming groove 111 from the insert strip guide groove 1171, and the insert strip 3 is cut by the movement of the shearing block 115 in the shearing groove 114 to obtain the insert strip.

[0038] Preferred, combined Figures 1 to 4 As shown, the upper mold 1 also includes an upper template 14 and an elastic element 143. The fixing plate 13 is located in the space between the upper template 14 and the stripping back plate 12. One end of the elastic element 143 acts on the upper template 14, and the other end of the elastic element 143 passes through the fixing plate 13 and acts on the stripping back plate 12. The linear actuator 142 is fixed to the upper template 14 and the driving end of the linear actuator 142 is connected to the fixing plate 13. The upper template 14 is connected to the driving end of the linear actuator 141.

[0039] Specifically, the fixing plate 13 is installed in the space reserved between the upper template 14 and the stripping back plate 12, forming a stable support structure. The elastic element 143 has one end directly connected to the upper template 14 and applies force, while the other end passes through the fixing plate 13 and acts on the stripping back plate 12, ensuring the reliability and stability of power transmission. The linear actuator 141 is connected to the upper template 14 in the upper mold 1, realizing the overall driving of the upper mold 1. The driving end of the linear actuator 142 is connected to the fixing plate 13, realizing the individual driving of the fixing plate 13 in the upper mold 1, achieving precise control of the shearing and stripping operations in the upper mold 1. The coordinated work of the two linear actuators improves production efficiency and control accuracy.

[0040] Preferred, combined Figure 1 , Figure 3 As shown, the upper mold 1 and the lower mold 2 are movably connected by a guide assembly, at least a portion of which is located on the upper mold 1 and the remaining portion of which is located on the lower mold 2.

[0041] Specifically, the guide assembly includes a guide post 133 and a guide groove 22, one of which is disposed in the upper mold 1 and the other in the lower mold 2.

[0042] Understandably, the guide assembly is used to guide the relative movement of the upper mold 1 and the lower mold 2, ensuring that the mold maintains precise coaxiality and movement trajectory during mold closing and opening, and avoiding machining errors or mold damage caused by offset.

[0043] Preferred, combined Figure 7 As shown, a travel limiting structure is provided between the shearing block 115 and the shearing groove 114. At least part of the travel limiting structure is provided in the shearing block 115, and the remaining part is provided in the shearing groove 114.

[0044] Specifically, the limiting structure includes a snap-fit ​​part 1151 and a snap-fit ​​groove 1141, one of which is disposed in the shearing insert 115 and the other is disposed in the shearing groove 114.

[0045] Understandably, when the shearing block 115 moves to its limit position, the locking part 1151 will cooperate with the locking groove 1141 to achieve the limiting function and prevent the shearing block 115 from moving further.

[0046] Specifically, the workflow of a strip forming mold with shearing function in this embodiment is as follows: The linear actuator 141 first pushes the upper template 14 down, and the upper template 14 presses the elastic element 143 down onto the stripping back plate 12. The stripping back plate 12 then contacts and presses down with the lifting insert forming plate 11. Finally, the lifting insert forming plate 11 contacts and presses down with the lower mold 2, so that the insert forming groove 111 in the upper mold 1 and the contour groove 21 in the lower mold 2 are connected vertically, which facilitates the cut and formed insert falling into the lower mold 2. The insert strip 3 enters the insert forming groove 111 of the lifting insert forming plate 11 through the insert strip guide groove 1171. After the induction relay at the top of the insert forming groove 111 senses the signal, the linear driver 142 presses down. The linear driver 142 pushes the fixing plate 13 down as well. Since the stripping part 131 and the insert knife 132 are fixedly installed on the fixing plate 13, the stripping part 131 and the insert knife 132 form a linkage to press down. During the pressing process, the inclined surface of the insert 132 extends into the shearing groove 114 and contacts the inclined surface of the shearing insert 115 to form an inclined surface mating structure. The inclined surface of the shearing insert 115 slides laterally under force and cuts the embedded strip 3 in the shearing groove 114 laterally, thus completing the shearing. Then the stripping section 131 contacts the stripping insert 112 and pushes the cut strip down into the contour groove 21 of the lower mold 2; After the above actions are completed, the linear actuator 142 drives the fixed plate 13 to lift up, and the stripping part 131 and the insert knife 132 inside the fixed plate 13 also lift up accordingly; the shearing block 115 returns to its original position under the push of the elastic element 116, and the stripping insert 112 also returns to its original position under the push of the elastic element 113. Subsequently, the linear actuator 141 lifts up, causing the lifting insert forming plate 11, the stripping back plate 12, and the upper template 14 to all rise and lift.

[0047] Example 2, combined with Figure 8 As shown, this embodiment provides an external embedded scoring device, including a turntable 100. The turntable 100 passes sequentially through an insert bar loading station 101, a housing loading station 102, a pressing station 103, and a unloading station 104 in a first rotation direction. The insert bar loading station 101 is provided with an insert bar forming mold with a shearing function, and the lower mold 2 of the insert bar forming mold with the shearing function is provided on the turntable 100.

[0048] Specifically, the workflow of an externally embedded scoring device in this embodiment is as follows: Four lower molds 2 are set on the turntable 100. Any one of the lower molds 2 first rotates to the insert feeding station 101. The upper mold 1 of the insert feeding station 101 pushes the cut and shaped insert into the contour groove 21 of the lower mold 2 through the operation steps in Embodiment 1. Then it rises and lifts up to make room for the turntable 100 to rotate. The turntable 100 rotates along the first rotation direction to the housing loading station 102, and places the aluminum housing on the lower mold 2; The turntable 100 rotates along the first rotation direction to the pressing station 103, and punches and marks the aluminum shell on the lower mold 2. Turntable 100 rotates along the first rotation direction to the unloading station 104, and takes out the scored aluminum shell.
