Description

Technical Field

[0001] This application relates to the field of stamping die technology, and in particular to a clutch bracket step forming die. Background Technology

[0002] The clutch mount is an important component of an automotive clutch system, primarily used to support and secure the clutch slave cylinder, ensuring its stability and reliability during operation. Clutch mounts are typically made of metal, possessing sufficient strength and rigidity to withstand the various forces and torques generated by the clutch slave cylinder during operation.

[0003] The related technology discloses a clutch bracket blank, referring to Figure 1 The body 01 is hollow inside and open at one end. The cross-section of the circumferential edge of the body 01 is corrugated. An installation port 02 is provided at the middle of the closed end of the body 01.

[0004] The next processing step for the clutch bracket blank is to machine a stepped crease 03 deep from the closed end to the open end of the body, thereby forming the finished clutch bracket. The stepped crease is to improve the structural strength of the clutch bracket.

[0005] However, due to the complex circumferential shape of the clutch bracket blank, directly stamping the stepped folds at the closed end of the body can easily deform the wavy edge of the body, resulting in changes in the dimensions of the finished clutch bracket. This affects the subsequent installation process of the matching structure, seriously impacting the clutch's functionality and leading to a low finished product qualification rate and shortcomings in the clutch bracket. Summary of the Invention

[0006] To improve the problem of low pass rate of processing clutch bracket blanks, this application provides a clutch bracket step forming mold.

[0007] The clutch bracket step forming mold provided in this application adopts the following technical solution:

[0008] A clutch bracket step forming mold includes a stationary mold and a moving mold opposite to the stationary mold. The stationary mold has a bottom post, and a punch post is coaxially mounted on the bottom post. A raised ring is coaxially mounted on the edge of the punch post facing the moving mold. The clutch bracket is coaxially slidably sleeved on the punch post, with the outer circumferential wall of the punch post tightly against the inner circumferential wall of the clutch bracket. The stationary mold has a demolding element for separating the punch post from the clutch bracket. The moving mold has a hollow section that opens towards the end facing the punch post. A concave module is slidably fitted onto a clutch bracket. The inner circumferential sidewall of the concave module is in close contact with the crest of the corrugated outer sidewall of the clutch bracket. An inner protrusion coaxial with the punch post is arranged inside the concave module. The diameter of the inner protrusion is smaller than the inner diameter of the convex ring. The inner protrusion is used to press the clutch bracket blank onto the convex ring. A pre-pressing component and a demolding component are provided on the moving die. The pre-pressing component is used to pre-press the clutch bracket blank onto the punch post. The demolding component is used to separate the machined clutch bracket from the concave module.

[0009] By adopting the above technical solution, the worker first places the clutch bracket blank onto the punch, so that the inner circumferential sidewall of the clutch bracket is in close contact with the outer circumferential sidewall of the punch. Then, the pre-pressing component pre-presses the clutch bracket blank onto the top of the punch. At this time, the inner top of the clutch bracket blank abuts against the convex ring of the punch. Then, during the process of the moving mold closing onto the stationary mold, the inner circumferential sidewall of the concave module is in close contact with the crest of the corrugated outer sidewall of the clutch bracket. At this time, the circumferential corrugated edge of the clutch bracket is fixed and cannot deform. At the same time, the inner convex column squeezes the closed end of the clutch bracket blank and forms a stepped crease together with the convex ring. Then, during the process of separating the moving mold and the stationary mold, the demolding component separates the processed clutch bracket from the punch, and the ejection component separates the processed clutch bracket from the concave module. This completes the processing of the clutch bracket and helps to improve the qualification rate of the finished clutch bracket.

[0010] Optionally, the demolding component includes a floating ring plate coaxially and slidably sleeved on the bottom post, a demolding module provided on the floating ring plate, the demolding module being used to abut against the open end of the clutch bracket, a guide post slidably provided on the stationary mold, the guide post being provided on the floating ring plate, the axis of the guide post being parallel to the axis of the floating ring plate, a gas spring provided on the stationary mold, the axis of the piston rod of the gas spring being parallel to the axis of the floating ring plate, and the floating ring plate being provided on the piston rod of the gas spring.

[0011] By adopting the above technical solution, during the separation of the moving mold and the stationary mold, the gas spring recovers its deformation and pushes the floating ring plate to slide closer to the moving mold. Under the restriction of the guide column, the floating ring plate drives the release module to push the open end of the clutch bracket to slide closer to the moving mold until the moving mold and the stationary mold are completely separated. At this time, the clutch bracket separates from the punch column.

[0012] Optionally, a signal transmitter and a signal receiver are provided on the stationary mold, both of which are electrically connected to the control system, and are located on both sides of the punch post.

[0013] By adopting the above technical solution, when the clutch bracket blank is fitted onto the punch, the clutch bracket blank blocks the signal receiver from receiving the signal generated by the signal transmitter. At this time, the control system knows that the clutch bracket blank has been placed on the punch.

[0014] Optionally, the pre-compression component includes a pre-compression cylinder arranged on the moving mold and electrically connected to the control system. The piston rod of the pre-compression cylinder slides through the inner protrusion, and a clamping block is provided on the piston rod of the pre-compression cylinder. The clamping block is used to press the clutch bracket blank onto the punch.

[0015] By adopting the above technical solution, when the control system receives the information fed back by the signal transmitter, the control system starts the pre-compression cylinder. The piston rod of the pre-compression cylinder extends and drives the clamping block to approach the clutch bracket blank until the clamping block presses the clutch bracket blank onto the punch column. During this process, the clutch bracket descends and pushes the release module. The release module drives the floating ring plate to descend synchronously, and the gas spring is compressed, reducing the possibility of the clutch bracket accidentally slipping off the punch column.

[0016] Optionally, the inner protruding post is slidably disposed on the concave module, and the concave module is provided with a clearance groove for the inner protruding post to slide. The mold ejection component includes a mold ejection cylinder disposed on the moving mold, and a mounting plate is disposed on the piston rod of the mold ejection cylinder. The pre-pressurization cylinder is disposed on the mounting plate, the inner protruding post is disposed on the mounting plate, and the concave module is provided with a stepped groove for the mounting plate to slide.

[0017] By adopting the above technical solution, after the moving mold and the stationary mold separate, the finished clutch bracket is stuck on the concave module. The control system starts the demolding cylinder, and the piston rod of the demolding cylinder extends. The piston rod of the demolding cylinder drives the inner protrusion to approach the stationary mold through the mounting plate. During this process, the inner protrusion pushes the finished clutch bracket in the concave module to slide until the finished clutch bracket separates from the concave module. Since the crest of the corrugated outer wall of the clutch bracket is close to the inner wall of the concave module, the shape and size of the circumferential outer wall of the clutch bracket will not change much during the stamping process. Moreover, since the contact area between the circumferential outer wall of the clutch bracket and the inner wall of the concave module is small, the friction between the clutch bracket and the concave module is also small, which facilitates the separation of the clutch bracket from the concave module.

[0018] Optionally, the bottom post is provided with a plurality of positioning posts, which are arranged circumferentially on the bottom post. The corrugated outer edge of the clutch bracket blank is located between the positioning posts and the punch post. The concave module is provided with a positioning slot for avoiding the positioning posts.

[0019] By adopting the above technical solution, workers can easily determine whether the clutch bracket blank is installed correctly.

[0020] Optionally, the punch column includes a base plate, a connecting ring seat, a first column module, and a second column module. The base plate is coaxially mounted on the base column, and the connecting ring seat is coaxially arranged with the base plate. Multiple first column modules are circumferentially evenly slidable on the base plate, and slide radially along the axis of the base plate. Multiple base plate slide bars are circumferentially evenly arranged on the base plate, each with a dovetail-shaped cross-section. Each base plate slide bar corresponds one-to-one with a first column module, and the first column module slides in conjunction with the base plate slide bar. A T-shaped connecting slide rail is provided on the first column module. The end of the connecting ring seat facing away from the base plate is inclined towards the base plate and has a connecting groove for the connecting slide rail to slide through. The connecting groove of the connecting ring seat faces the base plate. One end of the first column module is not open. The contact surface between the first column module and the connecting ring seat is inclined away from the connecting ring seat along the direction from the connecting ring seat to the bottom mounting plate. Multiple second column modules are circumferentially slidably arranged on the connecting ring seat. The second column modules correspond one-to-one with the first column modules. The second column modules and the first column modules are staggered circumferentially along the axis of the bottom mounting plate. The connecting ring seat is provided with a T-shaped anti-detachment slide rail. The end of the second column module facing away from the bottom mounting plate is inclined towards the bottom mounting plate and has an anti-detachment groove for the anti-detachment slide rail to slide. The end of the second column module facing the bottom mounting plate is not open. The contact surface between the second column module and the connecting ring seat is inclined towards the connecting ring seat along the direction from the connecting ring seat to the bottom mounting plate.

[0021] By adopting the above technical solution, during the separation of the moving mold and the stationary mold, the gas spring recovers its deformation. The gas spring drives the disengagement module through the floating ring plate to push the open end of the clutch bracket. The clutch bracket slides towards the moving mold. During this process, the stepped crease on the clutch bracket gradually moves between the convex ring and the moving mold. At this time, as the clutch bracket continues to slide, the friction between the clutch bracket and the first column module, and between the clutch bracket and the second column module, drives the second column module to slide towards the moving mold. Under the restriction of the anti-disengagement slide rail, the second column module slides along the inclined contact surface with the connecting ring seat. The distance between two adjacent second column modules continuously decreases. The module separates from the inner wall of the clutch bracket, while the second column module drives the connecting ring seat closer to the moving mold. During the sliding of the connecting ring seat, under the combined constraint of the connecting groove and the connecting slide rail, the first column module slides along the length direction of the chassis slide bar on the connecting ring seat towards the axis of the bottom mounting plate. The distance between two adjacent first column modules continuously decreases until the first column module separates from the inner wall of the clutch bracket. This allows the clutch bracket to quickly achieve the demolding effect. After the clutch bracket separates, the connecting ring seat, the first column module, and the second column module will reset under the action of gravity, which helps to reduce the difficulty of separating the clutch bracket from the punch column.

[0022] Optionally, the connecting ring seat is provided with a clearance notch for avoiding the chassis slide bar.

[0023] By adopting the above technical solution, the connecting ring seat can directly abut against the bottom mounting plate, which helps to improve the impact resistance between the bottom mounting plate, the connecting ring seat, the first column module and the second column module.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The worker first places the clutch bracket blank onto the punch, so that the inner circumferential wall of the clutch bracket is in close contact with the outer circumferential wall of the punch. Then, the pre-pressing component pre-presses the clutch bracket blank onto the top of the punch. At this time, the inner top of the clutch bracket blank abuts against the convex ring of the punch. Then, during the process of the moving mold closing onto the stationary mold, the inner circumferential wall of the concave module is in close contact with the crest of the corrugated outer wall of the clutch bracket. At this time, the circumferential corrugated edge of the clutch bracket is fixed and cannot deform. At the same time, the inner convex column squeezes the closed end of the clutch bracket blank and forms a stepped crease together with the convex ring. Then, during the process of the moving mold and the stationary mold separating, the demolding component separates the processed clutch bracket from the punch, and the ejection component separates the processed clutch bracket from the concave module. This completes the processing of the clutch bracket and helps to improve the qualification rate of the finished clutch bracket.

[0026] 2. After the moving mold and the stationary mold separate, the finished clutch bracket is stuck on the concave module. The control system starts the demolding cylinder, and the piston rod of the demolding cylinder extends. The piston rod of the demolding cylinder drives the inner protrusion to approach the stationary mold through the mounting plate. During this process, the inner protrusion pushes the finished clutch bracket in the concave module to slide until the finished clutch bracket separates from the concave module. Since the crest of the corrugated outer wall of the clutch bracket is close to the inner wall of the concave module, the shape and size of the circumferential outer wall of the clutch bracket will not change much during the stamping process. Moreover, since the contact area between the circumferential outer wall of the clutch bracket and the inner wall of the concave module is small, the friction between the clutch bracket and the concave module is also small, which facilitates the separation of the clutch bracket from the concave module.

[0027] 3. During the separation of the moving mold and the stationary mold, the gas spring recovers its deformation. The gas spring, through the floating ring plate, drives the release module to push the open end of the clutch bracket. The clutch bracket slides towards the moving mold. During this process, as the clutch bracket continues to slide, the friction between the clutch bracket and the first column module, and between the clutch bracket and the second column module, causes the second column module to slide towards the moving mold. Simultaneously, under the restraint of the anti-detachment slide rail, the second column module slides along the inclined contact surface with the connecting ring seat. The distance between two adjacent second column modules continuously decreases, and the second column module engages with the clutch... The inner wall of the clutch bracket separates, and at the same time, the second column module drives the connecting ring seat to approach the moving mold. During the sliding of the connecting ring seat, under the combined constraint of the connecting groove and the connecting slide rail, the first column module slides along the length direction of the chassis slide bar on the connecting ring seat towards the axis of the bottom mounting plate. The distance between two adjacent first column modules continuously decreases until the first column module separates from the inner wall of the clutch bracket. In this way, the clutch bracket can quickly achieve the demolding effect. After the clutch bracket separates, the connecting ring seat, the first column module and the second column module will reset under the action of gravity. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 2-8 This application will be described in further detail.

[0038] This application discloses a clutch bracket step forming mold.

[0039] Example 1

[0040] Reference Figure 2 A clutch bracket step forming mold includes a stationary mold 1 and a moving mold 2 opposite to the stationary mold 1. The moving mold 2 is located directly above the stationary mold 1. A signal transmitter 11 and a signal receiver 12 are bolted to the stationary mold 1. The signal transmitter 11 and the signal receiver 12 are both electrically connected to the control system. The signal transmitter 11 and the signal receiver 12 are located on both sides of the punch post 4.

[0041] Reference Figure 2 , Figure 3 and Figure 4Multiple positioning posts 14 are bolted to the bottom post 3. The multiple positioning posts 14 are arranged circumferentially on the bottom post 3. The corrugated outer edge of the clutch bracket 0 blank is located between the positioning posts 14 and the punch post 4. The concave module 7 is provided with a positioning slot 15 for avoiding the positioning posts 14.

[0042] Reference Figure 3 , Figure 4 and Figure 5 A bottom post 3 is bolted to the stationary mold 1, and a punch post 4 is coaxially bolted to the bottom post 3. A punch post 4 has a punch ring 5 integrally formed on the edge of the end of the punch post 4 facing the moving mold 2. The clutch bracket 0 is coaxially slidably sleeved on the punch post 4, and the outer circumferential wall of the punch post 4 is in close contact with the inner circumferential wall of the clutch bracket 0.

[0043] The worker places the clutch bracket blank 0 onto the punch post 4. At this time, the corrugated outer edge of the clutch bracket blank 0 is located between the positioning post 14 and the punch post 4. At the same time, the circumferential outer wall of the punch post 4 is in contact with the circumferential inner wall of the clutch bracket 0. The clutch bracket blank 0 blocks the signal transmission between the signal transmitter 11 and the signal receiver 12. The control system receives a signal feedback that the clutch bracket blank 0 has been placed.

[0044] Reference Figure 3 and Figure 4 A demolding component 6 is arranged on the stationary mold 1. The demolding component 6 is used to separate the punch post 4 from the clutch bracket 0. The demolding component 6 includes a floating ring plate 61 that is coaxially slidably sleeved on the bottom post 3. A demolding module 62 is bolted to the floating ring plate 61. The demolding module 62 is used to abut against the open end of the clutch bracket 0.

[0045] Reference Figure 4 A vertical guide post 63 is slidably arranged on the stationary mold 1. The axis of the guide post 63 is parallel to the axis of the floating ring plate 61. The guide post 63 is bolted to the floating ring plate 61. A gas spring 64 is bolted to the stationary mold 1. The axis of the piston rod of the gas spring 64 is parallel to the axis of the floating ring plate 61. The floating ring plate 61 is bolted to the piston rod of the gas spring 64.

[0046] Reference Figure 5 A hollow inner die 7 with an open end facing the punch post 4 is bolted to the moving die 2. The inner die 7 is slidably sleeved on the clutch bracket 0. The inner circumferential sidewall of the inner die 7 is in close contact with the crest of the corrugated outer sidewall of the clutch bracket 0.

[0047] Reference Figure 3 and Figure 5 The concave module 7 has an inner protruding post 8 coaxial with the punch post 4. The inner protruding post 8 slides vertically through the inner and outer walls of the concave module 7. The concave module 7 has a relief groove 13 for the inner protruding post 8 to slide. The diameter of the inner protruding post 8 is smaller than the inner diameter of the protruding ring 5. The inner protruding post 8 is used to press the clutch bracket 0 blank onto the protruding ring 5.

[0048] Reference Figure 3 , Figure 4 and Figure 5 A pre-pressing component 9 is arranged on the moving mold 2. The pre-pressing component 9 is used to pre-press the clutch bracket 0 blank onto the punch 4. The pre-pressing component 9 includes a pre-pressing cylinder 91 arranged on the moving mold 2 and electrically connected to the control system. The piston rod of the pre-pressing cylinder 91 slides through the inner punch 8. A clamping block 92 is bolted to the piston rod of the pre-pressing cylinder 91. The clamping block 92 is used to press the clutch bracket 0 blank onto the punch 4.

[0049] Reference Figure 3 The moving mold 2 is provided with a mold release component 10, which is used to separate the processed clutch bracket 0 from the concave module 7. The mold release component 10 includes a mold release cylinder 101 bolted to the moving mold 2. A mounting plate 102 is bolted to the piston rod of the mold release cylinder 101. A pre-pressurization cylinder 91 is bolted to the mounting plate 102. An inner protrusion 8 is bolted to the mounting plate 102. A stepped groove 103 is provided on the concave module 7 for the mounting plate 102 to slide.

[0050] The control system activates the pre-compression cylinder 91. The piston rod of the pre-compression cylinder 91 drives the clamping block 92 to press the clutch bracket 0 blank onto the punch column 4. At this time, the inner top wall of the clutch bracket 0 blank abuts against the punch ring 5, and the outer circumferential wall of the punch column 4 is in close contact with the inner circumferential wall of the clutch bracket 0 blank. During this process, the open end of the clutch bracket 0 blank pushes the release module 62 down, and the release module 62 continuously compresses the gas spring 64 through the floating ring plate 61.

[0051] During the process of moving mold 2 closing with stationary mold 1, the control system starts the pre-compression cylinder 91. The piston rod of the pre-compression cylinder 91 continuously contracts until the inner convex post 8 abuts against the clutch bracket 0 blank. As moving mold 2 continues to approach stationary mold 1, under the action of convex ring 5, the inner convex post 8 punches a stepped crease 03 into the closed end of the clutch bracket 0 blank.

[0052] During this process, the inner circumferential wall of the concave module 7 always restricts the corrugated outer wall of the clutch bracket 0 from deforming outward, while the convex die 4 restricts the corrugated inner wall of the clutch bracket 0 from deforming inward, thereby completing the processing of the stepped crease 03 of the clutch bracket 0.

[0053] During the separation of the moving mold 2 and the stationary mold 1, the gas spring 64 recovers its deformation. The piston rod of the gas spring 64 drives the floating ring plate 61 to rise. The floating ring plate 61 pushes the open end of the clutch bracket 0 to rise synchronously through the release module 62, thereby realizing the separation of the clutch bracket 0 from the punch column 4. The clutch bracket 0, which is separated from the punch column 4, is stuck on the inner wall of the concave module 7 by friction.

[0054] At this time, the control system starts the demolding cylinder 101, the piston rod of the demolding cylinder 101 extends, and the piston rod of the demolding cylinder 101 drives the inner protrusion 8 to descend through the mounting plate 102. The descending inner protrusion 8 pushes the clutch bracket 0 to descend until the clutch bracket 0 separates from the concave module 7, thus completing the processing of the clutch bracket 0.

[0055] The implementation principle of Example 1 is as follows: The worker places the clutch bracket 0 blank on the punch column 4. At this time, the corrugated outer edge of the clutch bracket 0 blank is located between the positioning column 14 and the punch column 4. At the same time, the circumferential outer wall of the punch column 4 is in contact with the circumferential inner wall of the clutch bracket 0. The clutch bracket 0 blank blocks the signal transmission between the signal transmitter 11 and the signal receiver 12. The control system receives a signal feedback that the clutch bracket 0 blank has been placed.

[0056] The control system activates the pre-compression cylinder 91. The piston rod of the pre-compression cylinder 91 drives the clamping block 92 to press the clutch bracket 0 blank onto the punch column 4. At this time, the inner top wall of the clutch bracket 0 blank abuts against the punch ring 5, and the outer circumferential wall of the punch column 4 is in close contact with the inner circumferential wall of the clutch bracket 0 blank. During this process, the open end of the clutch bracket 0 blank pushes the release module 62 down, and the release module 62 continuously compresses the gas spring 64 through the floating ring plate 61.

[0057] During the process of moving mold 2 closing with stationary mold 1, the control system starts the pre-compression cylinder 91. The piston rod of the pre-compression cylinder 91 continuously contracts until the inner convex post 8 abuts against the clutch bracket 0 blank. As moving mold 2 continues to approach stationary mold 1, under the action of convex ring 5, the inner convex post 8 punches a stepped crease 03 into the closed end of the clutch bracket 0 blank.

[0058] During this process, the inner circumferential wall of the concave module 7 always restricts the corrugated outer wall of the clutch bracket 0 from deforming outward, while the convex die 4 restricts the corrugated inner wall of the clutch bracket 0 from deforming inward, thereby completing the processing of the stepped crease 03 of the clutch bracket 0.

[0059] During the separation of the moving mold 2 and the stationary mold 1, the gas spring 64 recovers its deformation. The piston rod of the gas spring 64 drives the floating ring plate 61 to rise. The floating ring plate 61 pushes the open end of the clutch bracket 0 to rise synchronously through the release module 62, thereby realizing the separation of the clutch bracket 0 from the punch column 4. The clutch bracket 0, which is separated from the punch column 4, is stuck on the inner wall of the concave module 7 by friction.

[0060] At this time, the control system starts the demolding cylinder 101, the piston rod of the demolding cylinder 101 extends, and the piston rod of the demolding cylinder 101 drives the inner protrusion 8 to descend through the mounting plate 102. The descending inner protrusion 8 pushes the clutch bracket 0 to descend until the clutch bracket 0 separates from the concave module 7, thus completing the processing of the clutch bracket 0.

[0062] refer to Figure 6 , Figure 7 and Figure 8 The difference between this embodiment and embodiment 1 is that the punch column 4 includes a bottom mounting plate 41, a connecting ring seat 42, a first column module 43 and a second column module 44. The bottom mounting plate 41 is coaxially bolted to the bottom column 3. The connecting ring seat 42 is coaxially arranged with the bottom mounting plate 41 and is located directly above the bottom mounting plate 41. Multiple first column modules 43 are evenly slidably arranged around the bottom mounting plate 41.

[0063] refer to Figure 6 , Figure 7 and Figure 8 The first column module 43 slides radially along the axis of the base plate 41. Multiple base plate slide strips 45 are evenly bolted to the circumferential direction of the base plate 41. The extension line of the length direction of the base plate slide strip 45 intersects the axis of the base plate 41. The cross-section of the base plate slide strip 45 is dovetail-shaped. The base plate slide strip 45 corresponds one-to-one with the first column module 43. The first column module 43 and the base plate slide strip 45 slide in cooperation.

[0064] refer to Figure 6 , Figure 7 and Figure 8 The connecting ring seat 42 has a clearance notch 16 for avoiding the chassis slide bar 45. The first column module 43 has a connecting slide rail 46 with a T-shaped cross section welded to one end facing away from the bottom mounting plate 41. The connecting ring seat 42 has a connecting groove 47 for the connecting slide rail 46 to slide on the side facing away from the bottom mounting plate 41. The connecting groove 47 of the connecting ring seat 42 is not open at the end facing the bottom mounting plate 41.

[0065] refer to Figure 6 , Figure 7 and Figure 8 The contact surface between the first column module 43 and the connecting ring seat 42 is inclined away from the connecting ring seat 42 along the direction from the connecting ring seat 42 to the bottom mounting plate 41. Multiple second column modules 44 are evenly slidably arranged around the connecting ring seat 42, and each second column module 44 corresponds to a first column module 43.

[0066] refer to Figure 6 , Figure 7 and Figure 8The second column module 44 and the first column module 43 are arranged alternately along the axis of the bottom mounting plate 41. The connecting ring seat 42 has multiple anti-detachment slide rails 48 with T-shaped cross sections welded to one end facing away from the bottom mounting plate 41. The anti-detachment slide rails 48 correspond one-to-one with the second column module 44.

[0067] refer to Figure 6 , Figure 7 and Figure 8 The second column module 44 is inclined towards the bottom mounting plate 41 at one end and has an anti-detachment groove 49 for the anti-detachment slide rail 48 to slide. The anti-detachment groove 49 of the second column module 44 is not open at the end facing the bottom mounting plate 41. The contact surface between the second column module 44 and the connecting ring seat 42 is inclined towards the connecting ring seat 42 along the direction from the connecting ring seat 42 to the bottom mounting plate 41.

[0068] During the separation of the moving mold 2 and the stationary mold 1, the gas spring 64 recovers its deformation. The gas spring 64 drives the release module 62 through the floating ring plate 61 to push the open end of the clutch bracket 0. The clutch bracket 0 slides towards the moving mold 2. During this process, the step crease 03 on the clutch bracket 0 gradually moves above the convex ring 5.

[0069] At this time, as the clutch bracket 0 continues to slide, the friction between the clutch bracket 0 and the first column module 43, and between the clutch bracket 0 and the second column module 44, will cause the second column module 44 to slide along the direction closer to the moving mold 2. Under the restriction of the anti-detachment slide rail 48, the second column module 44 slides along the inclined contact surface between itself and the connecting ring seat 42, and the distance between two adjacent second column modules 44 continuously decreases.

[0070] The second column module 44 separates from the inner wall of the clutch bracket 0. At the same time, the second column module 44 drives the connecting ring seat 42 to approach the moving mold 2. During the vertical sliding of the connecting ring seat 42, under the combined restraint of the connecting groove 47 and the connecting slide rail 46, the first column module 43 slides along the length direction of the chassis slide bar 45 on the connecting ring seat 42 towards the axis of the bottom mounting plate 41, and the distance between two adjacent first column modules 43 continuously decreases.

[0071] Until the first column module 43 separates from the inner wall of the clutch bracket 0, the clutch bracket 0 can quickly achieve the demolding effect. After the clutch bracket 0 is completely separated from the first column module 43 and the second column module 44, the connecting ring seat 42, the first column module 43 and the second column module 44 will reset under the action of gravity.

[0072] The implementation principle of Example 2 is as follows: During the separation of the moving mold 2 and the stationary mold 1, the gas spring 64 recovers its deformation. The gas spring 64 drives the release module 62 through the floating ring plate 61 to push the open end of the clutch bracket 0. The clutch bracket 0 slides towards the moving mold 2. During this process, the step crease 03 on the clutch bracket 0 gradually moves to the top of the convex ring 5.

[0073] At this time, as the clutch bracket 0 continues to slide, the friction between the clutch bracket 0 and the first column module 43, and between the clutch bracket 0 and the second column module 44, will cause the second column module 44 to slide along the direction closer to the moving mold 2. Under the restriction of the anti-detachment slide rail 48, the second column module 44 slides along the inclined contact surface between itself and the connecting ring seat 42, and the distance between two adjacent second column modules 44 continuously decreases.

[0074] The second column module 44 separates from the inner wall of the clutch bracket 0. At the same time, the second column module 44 drives the connecting ring seat 42 to approach the moving mold 2. During the vertical sliding of the connecting ring seat 42, under the combined restraint of the connecting groove 47 and the connecting slide rail 46, the first column module 43 slides along the length direction of the chassis slide bar 45 on the connecting ring seat 42 towards the axis of the bottom mounting plate 41, and the distance between two adjacent first column modules 43 continuously decreases.

[0075] Until the first column module 43 separates from the inner wall of the clutch bracket 0, the clutch bracket 0 can quickly achieve the demolding effect. After the clutch bracket 0 is completely separated from the first column module 43 and the second column module 44, the connecting ring seat 42, the first column module 43 and the second column module 44 will reset under the action of gravity.

[0076] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
