Description

Technical Field

[0001] The present invention relates to the technical field of automotive front bumper bracket molds, and specifically to an automotive front bumper bracket mold. Background Art

[0002] The automotive front bumper bracket is a core structural component connecting the bumper outer shell and the vehicle body skeleton. As a rigid support structure for the bumper outer shell, it firmly fixes the bumper on the vehicle body, ensuring that the gap between it and the vehicle body is uniform and does not shake. At the same time, during a collision, it transmits the impact force to the energy-absorbing box or the vehicle body longitudinal beam to assist in dispersing the collision energy.

[0003] The automotive front bumper bracket is usually injection-molded from high-strength engineering plastics. After the automotive front bumper bracket is injection-molded, due to the large size of the support frame (length ≥ 1500 mm), too many ejector pins and uneven distribution, when automatically ejected, the unbalanced force will cause warping, and the automatic part-taking is prone to jamming or damaging the surface of the plastic part. Therefore, it is necessary for the staff to manually take the part.

[0004] However, during the opening process of the mold, situations such as the fracture of the safety valve spring resulting in the accidental release of the hydraulic lock, parameter setting and operation errors, etc., will cause the moving template to close due to its own weight. In this case, the staff who is manually taking the part does not receive a warning and has no time to withdraw in a short time, and the personal safety of the staff will be endangered, posing a very high safety risk to the part-taking personnel. Summary of the Invention

[0005] Aiming at the above-mentioned existing technical deficiencies, the purpose of the present invention is to provide an automotive front bumper bracket mold, which has the advantage that during the process of the staff manually taking the part, the blocking mechanism is triggered by the push plate linked by the control rod, and the blocking plate is automatically inserted between the moving template and the stationary template when the moving template rises, reducing the possibility of accidental closing endangering the staff and ensuring the safety of part-taking.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides an automotive front bumper bracket mold, including a base and a top plate located directly above the base. A stationary template is fixed on the upper surface of the base, and a moving template is fixed on the lower surface of the top plate. The combined surface of the stationary template and the moving template forms a cavity for the molded product of the automotive front bumper bracket. It is characterized in that the automotive front bumper bracket mold further includes a blocking mechanism, including a blocking plate arranged beside the stationary template. After the moving template rises, the blocking plate rotates and inserts between the moving template and the stationary template to play a blocking role; A supporting mechanism, including a support seat fixed on one side of the upper surface of the base. On the front and rear sides of the upper surface of the support seat, support frames are fixed. The tops of the two support frames are fixedly connected by a connecting plate, and an active component for controlling the rotation of the blocking plate is fitted on the connecting plate; The control mechanism includes a control rod fixed to one side of the outer wall of the top plate and having an L-shaped cross-section. The control rod is located beside the connecting plate. A push plate rotatably connected to the control rod is nested on the lower side of the control rod. After the moving template moves up to a proper position, the push plate cooperates with the movable component to control the rotation of the blocking plate.

[0007] By adopting the above technical solution, during the injection molding process, the blocking plate is located beside the moving template and the static template, without affecting the injection molding work.

Detailed implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] An automobile front bumper bracket mold, as Figures 1-10 , includes a base 1 and a top plate 2 located directly above the base 1. A stationary template 3 is fixed on the upper surface of the base 1, and a moving template 4 is fixed on the lower surface of the top plate 2. The combined surface of the stationary template 3 and the moving template 4 forms a cavity 5 for the molded product of the automobile front bumper bracket. The cooperation of the stationary template 3 and the moving template 4 for injection molding the automobile front bumper bracket is an existing device, so no more details will be described here.

[0023] As Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 and Figure 6, the base 1 extends to one side. A support seat 7 is fixed on the upper surface of the part of the base 1 extending out of the stationary template 3. On both the front and rear sides of the upper surface of the support seat 7, there are fixedly arranged support frames 8 arranged oppositely. The tops of the two support frames 8 are fixedly connected by a transverse connecting plate 9. A blocking plate 6 is arranged at the upper end of the support seat 7. Cross plates are fixed at both the top and bottom of the blocking plate 6. Reinforcing ribs for enhancing its support strength are fixed between the two cross plates and the blocking plate 6. The blocking plate 6 is located beside the stationary template 3. An activity component 10 for controlling the rotation of the blocking plate 6 is fitted on the connecting plate 9. After the moving template 4 rises, power is provided by the activity component 10, and the blocking plate 6 rotates and inserts between the moving template 4 and the stationary template 3 to play a blocking role.

[0024] As Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 and Figure 6 , the activity component 10 includes a connection block 1001 fixed to the outer wall of the connecting plate 9. A column 1002 rotatably connected to the connection block 1001 penetrates through the middle position of the connection block 1001. The bottom end of the column 1002 passing through the connection block 1001 is rotatably connected to the upper surface of the support seat 7. A follower rod 1003 with an L-shaped cross-section is fixed to the circumferential outer wall of the column 1002. A strip-shaped activity groove 1004 adapted to the follower rod 1003 is opened on the blocking plate 6. The follower rod 1003 is arranged in the strip-shaped activity groove 1004 and is slidably connected to the strip-shaped activity groove 1004. A through hole 1005 is penetrated through the blocking plate 6 at the middle position of the strip-shaped activity groove 1004. A first short shaft is fixed in the through hole 1005. One end of the follower rod 1003 away from the column 1002 bends towards the side of the first short shaft and is sleeved outside the first short shaft. The follower rod 1003 is movably connected to the first short shaft. A strip-shaped sliding groove 1006 is opened on the connecting plate 9. A slider 1007 is slidably connected in the strip-shaped sliding groove 1006. A second short shaft is rotatably connected to the slider 1007. The bottom end of the second short shaft extends out of the connecting plate 9 through the strip-shaped sliding groove 1006. The bottom end of the slider 1007 extending out of the connecting plate 9 is fixed to the blocking plate 6.

[0025] As Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 and Figure 6 , when the column 1002 rotates, it will drive the follower rod 1003 fixed to the column 1002 to rotate. The rotation of the follower rod 1003 will drive the blocking plate 6 to rotate around the first short shaft, so that one end of the blocking plate 6 inserts into the gap between the moving template 4 and the stationary template. Through the cooperation of the slider 1007 and the strip-shaped sliding groove 1006, a guiding and limiting effect is exerted on the rotation of the blocking plate 6.

[0026] As Figure 1 andFigure 2 and Figure 3 and Figure 4 and Figure 5 and Figure 6 At the top of the connecting block 1001, the column 1002 passes through and is coaxially fixed with a follower gear 1008. On the upper surface of the connecting block 1001, a sleeve 1009 is fixed, which is sleeved outside the follower gear 1008 and arranged coaxially with the follower gear 1008. Inside the sleeve 1009, a driving assembly is provided to control the rotation of the gear to drive the column 1002 and the follower rod 1003 to rotate. By providing power through the driving assembly, the rotation of the follower gear 1008 is controlled to drive the column 1002 and the follower rod 1003, which are of an integrated structure with the follower gear 1008, to rotate.

[0027] Such as Figure 7 and Figure 8 and Figure 9 The driving assembly includes a cylindrical hole 1010 opened at the middle position of the follower gear 1008. The cylindrical hole 1010 extends to the inside of the column 1002. Inside the cylindrical hole 1010, a connecting column 1011 adapted to the cylindrical hole 1010 is provided. The follower gear 1008 is also provided with a groove 1012 communicating with the cylindrical hole 1010. Inside the groove 1012, a strip-shaped protrusion 1013 adapted to the groove 1012 is slidably connected. The strip-shaped protrusion 1013 extends out of the groove 1012 and enters the cylindrical hole 1010. The strip-shaped protrusion 1013 entering the cylindrical hole 1010 is fixed to the outer wall of the connecting column 1011. The top of the connecting column 1011 extends out of the follower gear 1008 through the cylindrical hole 1010. At the top of the connecting column 1011 extending out of the follower gear 1008, a movable column 1014 is fixed. An arc-shaped groove 1015 is opened on the movable column 1014. Inside the arc-shaped groove 1015, a limiting block 1016 is slidably connected. The limiting block 1016 extends out of the arc-shaped groove 1015, and the limiting block 1016 extending out of the arc-shaped groove 1015 is fixed to the inner cavity wall of the sleeve 1009.

[0028] Such as Figure 7 and Figure 8 and Figure 9 When the movable column 1014 moves downward, through the cooperation of the limiting block 1016 and the arc-shaped groove 1015, the movable column 1014 rotates during the downward movement. The movable column 1014 and the strip-shaped protrusion 1013 move downward in the cylindrical hole 1010 and the groove 1012. Through the cooperation of the groove 1012 and the strip-shaped protrusion 1013, the rotation of the movable column 1014 will drive the column 1002 and the follower gear 1008 to rotate.

[0029] Such as Figure 7 and Figure 8 and Figure 9, a rack 13 is slidably connected to the inner cavity wall of the sleeve 1009 through a slide rail. The bottom end of the rack 13 is rotatably connected to the top of the movable column 1014. A power assembly for controlling the movement of the rack 13 along the central axis direction of the sleeve 1009 is provided on the sleeve 1009. By providing power through the power assembly, the rack 13 is driven to move in the vertical direction. The movement of the rack 13 will drive the movable column 1014 rotatably connected to the rack 13 to move in the vertical direction, and the rotation of the movable column 1014 will not affect the rack 13.

[0030] As Figure 7 and Figure 8 and Figure 9 , the power assembly includes a connecting shaft 14 passing through the sleeve 1009 and rotatably connected to the sleeve 1009. A half gear 15 coaxial with the connecting shaft 14 and located in the inner cavity of the sleeve 1009 is nested on the circumferential outer wall of the connecting shaft 14. The half gear 15 meshes with the rack 13. A connecting handle 16 is fixed on the half gear 15. A connecting groove 17 connecting the outside and the inner cavity of the sleeve 1009 is opened on the sleeve 1009. One end of the connecting handle 16 away from the half gear 15 passes through the sleeve 1009 through the connecting groove 17. The part of the connecting handle 16 passing through the sleeve 1009 is adapted to the size of the push plate 12. After the push plate 12 moves upward and contacts the connecting handle 16, the connecting handle 16 is pushed to rotate, thereby driving the connecting shaft 14 and the half gear 15 of the integral structure with the connecting handle 16 to rotate. The rotation of the half gear 15 will drive the rack 13 to move in the vertical direction, thereby controlling the rotation of the blocking plate 6.

[0031] As Figure 7 and Figure 8 and Figure 9 and Figure 10 , a circular plate 18 is fixed on the circumferential outer wall of the sleeve 1009 beside the connecting groove 17. A circular groove is opened in the inner cavity of the circular plate 18. One end of the connecting shaft 14 passes through the sleeve 1009 and is rotatably connected to the sleeve 1009. The end of the connecting shaft 14 passing through the sleeve 1009 enters the circular groove and is rotatably connected to the circular plate 18. A rotating disk 19 is coaxially fixed on the part of the connecting shaft 14 entering the circular groove. A limiting assembly 20 for restricting the high-speed rotation of the connecting shaft 14 is provided on the rotating disk 19. When the moving template 4 suddenly drops due to an accident and the push plate 12 contacts the connecting handle 16, the high-speed falling moving template 4 will cause the connecting shaft 14 to rotate rapidly. At this time, power is provided through the limiting assembly 20 to limit the speed of the connecting shaft 14, so that the connecting shaft 14 cannot continue to rotate, and further the half gear 15 cannot continue to rotate.

[0032] As Figure 10, the limiting component 20 includes an annular plate 2001 disposed in the circular groove and fixedly connected to the groove wall of the circular groove. A plurality of clamping grooves 2002 are formed in the inner cavity groove wall of the annular plate 2001. The plurality of clamping grooves 2002 are arranged in an array with the center line of the circular disk 18 as the center of the circle. A third short shaft 2003 and a fourth short shaft 2004 are rotatably connected to the rotating disk 19. A first clamping rod 2005 rotatably connected to the third short shaft 2003 is nested on the third short shaft 2003. A second clamping rod 2006 rotatably connected to the fourth short shaft 2004 is nested on the fourth short shaft 2004. Both the first clamping rod 2005 and the second clamping rod 2006 are adapted to the clamping grooves 2002. When the rotating speed of the connecting shaft 14 is too fast, the rotating disk 19 coaxially fixed to the connecting shaft 14 rotates rapidly. At this time, the first clamping rod 2005 and the second clamping rod 2006 rotate under the action of centrifugal force and are clamped and connected to the clamping grooves 2002.

[0033] As Figure 10 , an ear seat 2007 is fixed on the rotating disk 19. A long rod 2008 slidably connected to the ear seat 2007 penetrates through the ear seat 2007. A fixing plate 2009 is fixed on the circumferential outer wall of the long rod 2008. The fixing plate 2009 is fixedly connected to the ear seat 2007 through a spring 2010 sleeved outside the long rod 2008. One end of the long rod 2008 away from the ear seat 2007 is hinged to the second clamping rod 2006. A connecting rod 2011 is arranged between the first clamping rod 2005 and the second clamping rod 2006. Both ends of the connecting rod 2011 are rotatably connected to the adjacent first clamping rod 2005 and second clamping rod 2006 respectively.

[0034] As Figure 10 , a control rod 11 with an L-shaped cross-section is fixedly arranged on one side of the outer wall of the top plate 2. The control rod 11 is located beside the connecting plate 9. A push plate 12 rotatably connected to the control rod 11 is nested on the lower side of the control rod 11. After the moving template 4 is moved up to a suitable position, the push plate 12 cooperates with the connecting handle 16 to control the rotation of the blocking plate 6.

[0035] During use, during the injection molding process, the blocking plate 6 is located beside the moving template 4 and the stationary template 3, without affecting the injection molding work. After the injection molding is completed, the moving template 4 moves upward and separates from the stationary template 3, exposing the formed automotive front bumper bracket. At the same time, when the moving template 4 moves, it will drive the top plate 2, the control rod 11 and the push plate 12, which are of an integral structure with the moving template 4, to move upward. The control rod 11 and the push plate 12 move upward and contact the connecting handle 16, pushing the connecting handle 16 to rotate clockwise. The rotation of the connecting handle 16 will drive the semi-gear 15 fixed to the connecting handle to rotate. The rotation of the semi-gear 15 will drive the rack 13 engaged with the semi-gear 15 to move up and down in the vertical direction. The rack 13 will drive the movable column 1014 rotatably connected to the rack 13 to move downward. Through the cooperation of the limit block 1016 and the arc groove 1015, the movable column 1014 rotates during the downward movement. The movable column 1014 and the strip protrusion 1013 move downward in the cylindrical hole 1010 and the groove 1012. Through the cooperation of the groove 1012 and the strip protrusion 1013, the rotation of the movable column 1014 will drive the upright column 1002 and the follower gear 1008 to rotate and not move in the vertical direction; The rotation of the upright column 1002 and the follower gear 1008 will drive the follower rod 1003 fixed to the upright column 1002 to rotate. The rotation of the follower rod 1003 will drive the blocking plate 6 to rotate around the first short axis, so that one end of the blocking plate 6 is inserted into the gap between the moving template 4 and the stationary template without affecting the workpiece taking. Through the cooperation of the slider 1007 and the strip chute 1006, it plays a guiding and limiting role in the rotation of the blocking plate 6; Before workpiece taking, the staff rotates the push plate 12 so that the push plate 12 is not directly above the connecting handle 16. At this time, once the moving template 4 accidentally falls due to its own weight, the push plate 12 does not contact the connecting handle 16. The blocking plate 6 located between the moving template 4 and the stationary template 3 plays a blocking role in the downward moving moving template 4, slowing down the downward movement time of the moving template 4, providing the staff who is taking the workpiece with a withdrawal time, reducing the possibility of harm to the personal safety of the staff, and reducing the safety risk of the workpiece taking personnel; After workpiece taking, the staff rotates the push plate 12 in the reverse direction so that the push plate 12 is directly above the connecting handle 16. At this time, when the moving template 4 falls normally, since the connecting handle 16 rotates clockwise to a high position during the upward push of the previous push plate 12 in this case, the push plate 12 moves downward to push the high-position connecting handle 16 to rotate counterclockwise to a low position, without affecting the normal use of the device. Since the inclination angle of the rack 13 is less than the pressure angle of the semi-gear 15 to form a frictional force, this frictional force can prevent the semi-gear 15 from reversing, realizing the self-locking of the semi-gear 15; When the staff forgets to rotate the push plate 12 and the moving template 4 falls due to accidental self-weight, the push plate 12 contacts the connecting handle 16 and pushes the connecting handle 16 to rotate in the reverse direction. The high-speed reverse rotation of the connecting handle 16 will drive the half gear 15 and the connecting shaft 14 fixed to the connecting handle to rotate at high speed. At this time, the high-speed rotation of the connecting shaft 14 will drive the rotating disk 19 coaxially fixed to the connecting shaft 14 to rotate at high speed in the circular groove. At this time, the first latch 2005 and the second latch 2006 rotate around the third short shaft 2003 and the fourth short shaft 2004 respectively under the action of centrifugal force, the spring 2010 is compressed, and the first latch 2005 and the second latch 2006 rotate and snap into the adjacent card slots 2002.
