Description

Technical Field

[0001] The invention relates to the technical field of automobile front bumper bracket molds, in particular to an automobile front bumper bracket mold. Background Art

[0002] The front bumper bracket of a car is the core structural component that connects the bumper shell to the body frame. As the rigid support structure of the bumper shell, it firmly fixes the bumper to the body, ensuring that the gap between it and the body is uniform and does not shake. At the same time, it transmits the impact force to the energy absorption box or the body longitudinal beam during a collision to help disperse the collision energy.

[0003] Automobile front bumper brackets are usually made of high-strength engineering plastic injection molding. After the automobile front bumper bracket is injection molded, due to the large size of the support frame (length ≥1500mm), there are too many ejectors and their uneven distribution. The unbalanced force during automatic ejection will cause warping. The automated removal process is prone to getting stuck or damaging the surface of the plastic part, so manual removal is required.

[0004] However, during the mold opening process, the hydraulic lock may be accidentally released due to the breakage of the safety valve spring, and parameter setting and operation errors may cause the dynamic template to close due to its own weight. In this case, the staff who are manually removing the parts will not receive any early warning and will not have time to withdraw in a short time. The personal safety of the staff will be endangered, posing an extremely high safety risk to the personnel removing the parts. Summary of the Invention

[0005] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a car front bumper bracket mold, which has the advantage that when the staff manually removes the parts, the blocking mechanism is triggered by the push plate linked by the control lever, and the blocking plate is automatically inserted when the movable template is raised, thereby reducing the possibility of accidental closure endangering the staff and ensuring the safety of removing the parts.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] The present invention provides a mold for a front bumper bracket of an automobile, comprising a base and a top plate located directly above the base, a static die plate fixed to the upper surface of the base, and a dynamic die plate fixed to the lower surface of the top plate, wherein the joining surface of the static die plate and the dynamic die plate forms a cavity for forming a molded product of the front bumper bracket of the automobile. The mold for the front bumper bracket of the automobile is characterized in that the mold further comprises a blocking mechanism, comprising a blocking plate disposed beside the static die plate, wherein after the dynamic die plate is raised, the blocking plate rotates and is inserted between the dynamic die plate and the static die plate to serve as a blocking mechanism.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] A car front bumper bracket mold, such as Figure 1-10 , including a base 1 and a top plate 2 located directly above the base 1, a static template 3 is fixed to the upper surface of the base 1, and a dynamic template 4 is fixed to the lower surface of the top plate 2. The combined surface of the static template 3 and the dynamic template 4 forms a cavity 5 for forming a molded product of the automobile front bumper bracket. The static template 3 and the dynamic template 4 cooperate to injection mold the automobile front bumper bracket, which is an existing equipment, so it will not be described in detail here.

[0036] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 and Figure 6The base 1 extends to one side, and a supporting seat 7 is fixed on the upper surface of the part of the base 1 extending out of the static template 3. Oppositely arranged support frames 8 are fixed on the front and rear sides of the upper surface of the supporting seat 7. The tops of the two support frames 8 are fixedly connected by a horizontal connecting plate 9. A blocking plate 6 is provided on the upper end of the supporting seat 7. The top and bottom of the blocking plate 6 are fixed with horizontal plates. Reinforcing ribs are fixed between the two horizontal plates and the blocking plate 6 to increase the support strength. The blocking plate 6 is located next to the static template 3, and the connecting plate 9 is equipped with a movable component 10 for controlling the rotation of the blocking plate 6. After the dynamic template 4 is raised, power is provided by the movable component 10, and the blocking plate 6 rotates and is inserted between the dynamic template 4 and the static template 3 to play a blocking role.

[0037] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 and Figure 6 The movable component 10 includes a connecting block 1001 fixed to the outer wall of the connecting plate 9, and a column 1002 rotatably connected to the connecting block 1001 is passed through the middle position of the connecting block 1001. The column 1002 passes through the bottom end of the connecting block 1001 and 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 outer wall of the column 1002. A strip movable groove 1004 adapted to the follower rod 1003 is opened on the blocking plate 6. The follower rod 1003 is arranged in the strip movable groove 1004 and is slidably connected to the strip movable groove 1004. The blocking plate 6 is penetrated by a column located on the strip There is a through hole 1005 in the middle of the movable groove 1004, and a first short shaft is fixed in the through hole 1005. The end of the follower rod 1003 away from the column 1002 is bent toward 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, and a strip slide groove 1006 is provided on the connecting plate 9. A slider 1007 is slidingly connected in the strip slide groove 1006, and 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 slide groove 1006, and the slider 1007 extends out of the bottom end of the connecting plate 9 and is fixedly connected to the blocking plate 6.

[0038] like 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 axis, so that one end of the blocking plate 6 is inserted into the gap between the movable template 4 and the static template. Through the cooperation of the slider 1007 and the strip slide groove 1006, the rotation of the blocking plate 6 is guided and limited.

[0039] like Figure 1 and Figure 2 and Figure 3 and Figure 4 and Figure 5 and Figure 6 The top of the column 1002 passing through the connecting block 1001 is coaxially fixed with a follower gear 1008, and the upper surface of the connecting block 1001 is fixed with a sleeve 1009 which is sleeved outside the follower gear 1008 and coaxially arranged with the follower gear 1008. A driving component for controlling the rotation of the gear to drive the rotation of the column 1002 and the follower rod 1003 is provided in the sleeve 1009. The driving component provides power to control the rotation of the follower gear 1008 to drive the rotation of the column 1002 and the follower rod 1003 which are an integrated structure with the follower gear 1008.

[0040] like Figure 7 and Figure 8 and Figure 9 The driving assembly includes a cylindrical hole 1010 provided in the middle of the follower gear 1008, the cylindrical hole 1010 extends to the inner side of the column 1002, a connecting column 1011 adapted to the cylindrical hole 1010 is provided in the cylindrical hole 1010, and a groove 1012 connected to the cylindrical hole 1010 is also provided on the follower gear 1008, a strip protrusion 1013 adapted to the groove 1012 is slidably connected in the groove 1012, and the strip protrusion 1013 extends out of the groove 1012 and enters the cylindrical hole 1010, and enters the cylindrical hole 1010. The strip-shaped protrusion 1013 in 010 is fixed to the outer wall of the connecting column 1011, and the top of the connecting column 1011 extends a follower gear 1008 through the cylindrical hole 1010. A movable column 1014 is fixed to the top of the connecting column 1011 extending the follower gear 1008. An arc groove 1015 is opened on the movable column 1014, and a limiting block 1016 is slidingly connected in the arc groove 1015. The limiting block 1016 extends out of the arc groove 1015, and the limiting block 1016 extending out of the arc groove 1015 is fixed to the inner groove wall of the sleeve 1009.

[0041] like Figure 7 and Figure 8 and Figure 9 When the movable column 1014 moves downward, the limit block 1016 and the arc groove 1015 cooperate to make the movable column 1014 rotate during the downward movement. The movable column 1014 and the bar protrusion 1013 move downward in the cylindrical hole 1010 and the groove 1012. Through the cooperation of the groove 1012 and the bar protrusion 1013, the rotation of the movable column 1014 will drive the column 1002 and the follower gear 1008 to rotate.

[0042] like Figure 7 and Figure 8 and Figure 9The inner groove wall of the sleeve 1009 is slidably connected to the rack 13 through a slide rail, and the bottom end of the rack 13 is rotatably connected to the top of the movable column 1014. The sleeve 1009 is provided with a power component for controlling the rack 13 to move along the center line direction of the sleeve 1009. The power component provides power to drive the rack 13 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.

[0043] like Figure 7 and Figure 8 and Figure 9 The power assembly includes a connecting shaft 14 that passes through the sleeve 1009 and is rotatably connected to the sleeve 1009. A half gear 15 is nested on the circumferential outer wall of the connecting shaft 14, which is coaxially fixed with the connecting shaft 14 and located in the inner cavity of the sleeve 1009. The half gear 15 is meshed with the rack 13. A connecting handle 16 is fixed on the half gear 15. A connecting groove 17 connecting the outside world and the inner cavity of the sleeve 1009 is opened on the sleeve 1009. The 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 that passes through the sleeve 1009 is adapted to the size of the push plate 12. After the push plate 12 moves up and contacts the connecting handle 16, it pushes the connecting handle 16 to rotate, thereby driving the connecting shaft 14 and the half gear 15 of the integrated 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.

[0044] like Figure 7 and Figure 8 and Figure 9 and Figure 10 A circular disk 18 is fixed on the outer wall of the sleeve 1009 and is located next to the connecting groove 17. A circular groove is opened in the inner cavity of the circular disk 18. One end of the connecting shaft 14 passes through the sleeve 1009 and is rotatably connected to the sleeve 1009. One end of the connecting shaft 14 passes through the sleeve 1009 and enters the circular groove and is rotatably connected to the circular disk 18. A rotating disk 19 is coaxially fixed to the part of the connecting shaft 14 entering the circular groove. The rotating disk 19 is provided with a limiting component 20 that limits the high-speed rotation of the connecting shaft 14. When the movable template 4 suddenly falls due to an accident and the push plate 12 contacts the connecting handle 16, the high-speed falling movable template 4 will cause the connecting shaft 14 to rotate rapidly. At this time, power is provided by the limiting component 20 to limit the speed of the connecting shaft 14, so that the connecting shaft 14 cannot continue to rotate, and the half gear 15 cannot continue to rotate.

[0045] like Figure 10The limiting component 20 includes an annular plate 2001 arranged in a circular groove and fixedly connected to the wall of the circular groove. A plurality of slots 2002 are opened on the inner wall of the annular plate 2001. The plurality of slots 2002 are arranged in an array with the center line of the circular disk 18 as the center of the circle. The rotating disk 19 is rotatably connected to a third short shaft 2003 and a fourth short shaft 2004. A first clamping rod 2005 rotatably connected to the third short shaft 2003 is nested on the third short shaft 2003, and a second clamping rod 2006 rotatably connected to the fourth short shaft 2004 is nested on the fourth short shaft 2004. The first clamping rod 2005 and the second clamping rod 2006 are both adapted to the slot 2002. When the rotating speed of the connecting shaft 14 is too fast, the rotating disk 19 coaxially fixed with 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 with the slot 2002.

[0046] like Figure 10 An ear seat 2007 is fixed on the rotating disk 19, and a long rod 2008 is passed through the ear seat 2007 and is slidingly connected to the ear seat 2007. A fixing plate 2009 is fixed to the circumferential outer wall of the long rod 2008. The fixing plate 2009 and the ear seat 2007 are fixedly connected by a spring 2010 sleeved on the outside of the long rod 2008. One end of the long rod 2008 away from the ear seat 2007 is hingedly connected to the second clamping rod 2006. A connecting rod 2011 is provided between the first clamping rod 2005 and the second clamping rod 2006. The two ends of the connecting rod 2011 are respectively rotatably connected to the adjacent first clamping rod 2005 and the second clamping rod 2006.

[0047] like Figure 10 A control rod 11 with an L-shaped cross-section is fixed on one side of the outer wall of the top plate 2. The control rod 11 is located next to 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 movable template 4 moves to a suitable position, the push plate 12 cooperates with the connecting handle 16 to control the rotation of the blocking plate 6.

[0048] During use, during the injection molding process, the blocking plate 6 is located beside the movable template 4 and the static template 3 and does not affect the injection molding work. After the injection molding is completed, the movable template 4 moves up and separates from the static template 3, exposing the molded front bumper bracket of the car. At the same time, when the movable template 4 moves, it will drive the top plate 2, the control rod 11 and the push plate 12 of the integrated structure with the movable template 4 to move up. The control rod 11 and the push plate 12 move up and contact with the connecting handle 16, pushing the connecting handle 16 to rotate clockwise. The rotation of the connecting handle 16 will drive the half gear 15 fixed to the connecting handle to rotate, and the rotation of the half gear 15 will drive the The rack 13 engaged with the half gear 15 moves downward in the vertical direction, and the rack 13 drives the movable column 1014, which is rotatably connected to the rack 13, to move downward. The movable column 1014 rotates during the downward movement through the cooperation of the limit block 1016 and the arc groove 1015. The movable column 1014 and the bar protrusion 1013 move downward in the cylindrical hole 1010 and the groove 1012. Through the cooperation of the groove 1012 and the bar protrusion 1013, the rotation of the movable column 1014 drives the column 1002 and the follower gear 1008 to rotate without moving in the vertical direction.

[0049] The rotation of the column 1002 and the follower gear 1008 drives the follower rod 1003 fixed to the column 1002 to rotate. The rotation of the follower rod 1003 drives 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 movable plate 4 and the static plate without affecting the removal of the parts. The cooperation between the slider 1007 and the strip-shaped slide groove 1006 plays a guiding and limiting role in the rotation of the blocking plate 6.

[0050] Before picking up the items, the staff rotates the push plate 12 so that the push plate 12 is not directly above the connecting handle 16. At this time, if the movable plate 4 accidentally falls due to its own weight, the push plate 12 will not contact the connecting handle 16. The blocking plate 6 located between the movable plate 4 and the static plate 3 will block the moving plate 4 from moving downward, slowing down the moving plate 4 and providing the staff who are picking up the items with time to withdraw, thereby reducing the possibility of endangering the personal safety of the staff and reducing the safety risks of the personnel picking up the items.

[0051] After taking the item, the staff rotates the push plate 12 in the opposite direction so that the push plate 12 is located just above the connecting handle 16. When the movable plate 4 falls normally, the connecting handle 16 rotates clockwise to the high position during the previous upward push of the push plate 12. At this time, the push plate 12 moves downward to push the high-position connecting handle 16 to rotate counterclockwise to the low position, which does not affect the normal use of the device. Since the inclination angle of the rack 13 is smaller than the pressure angle of the half gear 15, a friction force is formed. This friction force can prevent the half gear 15 from reversing, thereby realizing the self-locking of the half gear 15.

[0052] When the staff forgets to rotate the push plate 12 and the movable template 4 falls due to accidental weight, the push plate 12 contacts the connecting handle 16 and pushes the connecting handle 16 to rotate in the opposite 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 with the connecting shaft 14 to rotate in the circular groove at high speed. At this time, the first clamping rod 2005 and the second clamping rod 2006 rotate around the third short shaft 2003 and the fourth short shaft 2004 respectively under the action of centrifugal force, and the spring 2010 is compressed. The first clamping rod 2005 and the second clamping rod 2006 rotate and are stuck in the adjacent clamping groove 2002. At this time, the connecting shaft 14 cannot continue to rotate, the half gear 15 cannot continue to rotate, and the blocking plate 6 cannot be retracted. At this time, the blocking plate 6 can still serve as a safety barrier for the staff.
