Description

Technical Field

[0001] The utility model relates to the technical field of die-casting machine parts, in particular to a movable template brake locking device. Background Art

[0002] The essence of die casting is to pour the molten or semi-molten alloy into the pressure chamber of the die casting machine, and then fill it into the cavity of the die casting mold at a very high speed under the action of high pressure, and cool and solidify the molten alloy under high pressure. It is a high-efficiency and high-precision casting method.

[0003] The die-casting machine's clamping structure is mostly a three-platen clamping structure, in which the movable template and the rear template are guided for movement and docking by means of a coring column. In the die-casting process of the three-platen structure, a die-casting mold is installed on the model surface of the template, and the relative fixation and release between the movable template and the rear template are coordinated for tightening and loosening. During the process of engagement, tightening and loosening between the movable template and the rear template, there will inevitably be a fitting gap in the guide structure in which the two movable templates move on the coring column. During the process of tightening and loosening, the tightening between the movable template and the rear template is prone to failure and deviation in positioning after tightening. In the case of inaccurate tightening and docking position of the middle plate, the die-casting model may be misaligned.

[0004] In the prior art, for example, the U.S. invention patent US20030217829A1 discloses a double-platen die-casting machine, which positions and limits the movable template by means of a threaded sleeve piston, and provides a locking mold enhancement pressure by means of hydraulic oil in the sleeved piston cylinder. In this scheme, the engaging force between the movable template and the rear template is good, but the locking structure itself is relatively complicated, and it is easy for the locking to fail when problems occur with the piston cylinder components and the limiting thread teeth, and the die-casting work cannot be continued, and the docking accuracy between the movable template and the rear template may not be accurate enough.

[0005] At the same time, for example, Chinese utility model patent CN209077760U discloses a brake structure of a two-plate die-casting machine. In this utility model patent, an oil cylinder is used to drive the brake block to directly squeeze and clamp the outer tooth part. In this clamping structure, since the matching contact surface between the brake block and the outer tooth is a groove structure, docking misalignment is easy to occur, resulting in axial sliding or contact surface damage, resulting in failure of clamping and positioning, and the docking accuracy may have a large deviation.

[0048] See attached Fig.11 To Attachment Fig.16 As shown, a clamping oil chamber 41 is provided in the clamping oil cylinder body 40, and a clamping piston rod 42 is slidably connected in the clamping oil chamber 41. A clamping oil port 43 is provided at the upper end of the clamping oil cylinder body 40, and the clamping oil port 43 is communicated with the clamping oil chamber 41. The clamping piston rod 42 is slidably connected through a through hole in the clamping synchronous seat 44, and the through hole penetrates the clamping synchronous seat 44. A synchronous threaded hole 47 is provided at both ends of the clamping synchronous seat 44. The lower end of the synchronous threaded hole 47 is slidably connected to the synchronous bracket shaft 50 through a countersunk hole. The upper end of the synchronous threaded hole 47 is rotatably connected to a synchronous fixing bolt 54, and the lower end of the synchronous fixing bolt 54 is rotatably connected to the synchronous bracket shaft 50. A monitoring expansion hole 48 is provided at the right end of the clamping synchronous seat 44.

[0049] The clamping synchronous seat 44 is fixedly connected to the lower end surface of the clamping oil cylinder body 40, and the two are rigidly connected, which assists the clamping synchronous seat 44 and the clamping oil cylinder body 40 in synchronizing the movement states, and provides an up and down sliding channel for the clamping piston rod 42 through the through hole penetrating the clamping synchronous seat 44, so as to prevent interference with the movement of the clamping piston rod 42, and at the same time, can store and shield a part of the exposed surface of the clamping piston rod 42, so as to protect the surface quality of the clamping piston rod 42 and improve its service life; by setting the monitoring expansion hole 48, the clamping position detection components can be installed on the clamping synchronous seat 44, which can improve the expansion convenience of the clamping movement position detection of the clamping piston rod 42 and the clamping oil cylinder body 40;

[0050] By providing a clamping synchronization seat 44, a first gate seat 51, a second gate seat 52 and an isolating limit block 53, the clamping piston rod 42 can be accommodated and protected, and the first gate seat 51 and the second gate seat 52 can be isolated and limited in cooperation with the clamping extrusion force to share a part of the clamping extrusion deformation, thereby improving the surface quality of the brake clamping structure and the accuracy of the limit of the brake clamping contact part, reducing the possibility of mechanical damage to the die-casting machine parts due to the clamping pressure during the brake clamping process, reducing the possibility of deformation dislocation during the brake clamping process, and improving the accuracy and reliability of the clamping position between the moving template and the rear template.

[0051] Both left and right ends of the second gate seat 52 are provided with synchronous docking holes 56 , and the synchronous support shaft 50 is rotatably connected in the synchronous docking holes 56 .

[0052] See attached Fig.12 To Attachment Fig.15 As shown, both left and right ends of the first gate seat 51 are provided with through holes, and the first gate seat 51 is slidably connected to the two synchronous bracket shafts 50 through the through holes;

[0053] The synchronous support shaft 50 is fixedly connected to the second gate seat 52 through the synchronous docking hole 56, and can fix the two sides of the second gate seat 52 synchronously, and under the rigid connection of the clamping synchronous seat 44 and the guiding cooperation of the clamping guide hole 22, when the rodless chamber hydraulic oil in the clamping oil chamber 41 increases, it will drive the clamping piston rod 42 to separate from the clamping oil cylinder body 40. At this time, the clamping oil cylinder body 40, the clamping synchronous seat 44, the synchronous support shaft 50, the second gate seat 52 and the isolation limit block 53 are kept in a synchronous motion state of sliding in the up and down directions in the clamping guide hole 22. At the same time, the through holes provided at the left and right ends of the first gate seat 51 guide the sliding of the synchronous support shaft 50, and can further cooperate with the clamping guide hole 22 to limit and guide the sliding of the synchronous support shaft 50, which can improve the guiding accuracy of the synchronous support shaft 50 driving the second gate seat 52 and the isolation limit block 53 to slide up and down synchronously to tighten and release.

[0054] At the same time, the through holes arranged at the left and right ends of the first gate seat 51 can limit the synchronous moving plane formed by the axis of the synchronous bracket shaft 50 and the middle connecting plane of the second gate seat 52 to the longitudinal plane of the axis of the clamping piston rod 42 in the clamping installation cavity 21. When the first gate seat 51 slides relatively on the synchronous bracket shaft 50 following the clamping piston rod 42, the two gate clamping surfaces 58 on the first gate seat 51 and the second gate seat 52 always keep their positions aligned during the clamping and releasing actions, thereby improving the smoothness and accuracy of the cooperation between the first gate seat 51 and the second gate seat 52 and the gate clamping docking groove 65, and improving the reliability of the clamping and releasing actions of the middle plate clamping, thereby improving the clamping force alignment effect at the die-casting mold on the transfer template.

[0055] See attached Fig.15 As shown, a gate tightening adapter hole 55 is provided at the upper end of the first gate seat 51, and the gate tightening adapter hole 55 is rotatably connected to the clamping piston rod 42;

[0056] The upper end surface of the first gate seat 51 and the lower end surface of the second gate seat 52 are respectively provided with a positioning surface 59, and the two positioning surfaces 59 cooperate with the upper and lower end surfaces of the clamping installation cavity 21 respectively, so that the assembly accuracy of the fixed connection between the clamping piston rod 42 and the first gate seat 51 can be improved under the positioning effect of the positioning surfaces 59, and the overall manufacturing cost of the device and the versatility of parts replacement can be reduced;

[0057] The lower end of the clamping piston rod 42 is rotatably connected to the first gate seat 51 through the gate clamping adapter hole 55. The clamping piston rod 42 is detachably connected to drive the first gate seat 51 to move up and down. When the brake is clamped, hydraulic oil is introduced into the clamping oil chamber 41 through the clamping oil port 43, so that the rodless cavity space in the clamping oil chamber 41 becomes larger, and the clamping piston rod 42 is pushed downward under the action of oil pressure. At this time, the clamping piston rod 42 drives the first gate seat 51 to slide downward in the clamping installation cavity 21 into a position that cooperates with the gate clamping docking groove 65. At this time, the gate clamping docking groove 65 on the clamping docking joint 64 limits the downward movement of the first gate seat 51 and the clamping piston rod 42. At this time, when the hydraulic oil in the rodless cavity in the clamping oil chamber 41 continues to increase, under the action of oil pressure , the clamping oil cylinder body 40 is pushed to move relatively away from the clamping piston rod 42, and at the same time drives the clamping synchronous seat 44, the synchronous bracket shaft 50, the second gate seat 52 and the isolation limit block 53 to move upward synchronously, thereby driving the second gate seat 52 to enter the matching position in the gate docking groove 65. When the oil pressure in the clamping oil chamber 41 continues to increase, the extrusion force is provided to make the first gate seat 51 and the second gate seat 52 clamp the gate docking groove 65 to limit the clamping joint 64, thereby fixing the relative position state between the rear template 60 and the movable template 10 when the clamping joint 64 enters the matching clamping joint chamber 15, thereby improving the clamping structure effect of the middle plate clamping brake and the docking positioning accuracy between the die-casting templates, and improving the stability of the clamping of the middle plate clamping brake of the die-casting machine;

[0058] By providing the brake adapter hole 55, the clamping piston rod 42, the synchronous bracket shaft 50 and the clamping installation cavity 21, the clamping oil cylinder body 40 can drive the first brake seat 51 and the second brake seat 52 to simultaneously approach the clamping docking head 64 to connect to the brake docking groove 65, and can simultaneously drive the first brake seat 51 and the second brake seat 52 to dock in the brake docking groove 65 for clamping or detach from the brake docking groove 65 for loosening according to the real-time change of the oil pressure in the clamping oil cylinder body 40 during the process of clamping and releasing the brake; After one of the gate seat 51 and the second gate seat 52 contacts the gate fastening docking groove 65, it plays a limiting function on the reaction force of the non-clamping extrusion generated by the other first gate seat 51 or the second gate seat 52 that has not yet matched with the gate fastening docking groove 65, and provides a reaction force limit for the clamping oil cylinder body 40 and the clamping piston rod 42 as a whole, so that after the oil pressure in the clamping oil cylinder body 40 continues to increase, it drives the other part of the first gate seat 51 and the second gate seat 52 that has not completed the docking in the gate fastening docking groove 65 to complete the clamping The docking improves the reliability of the clamping and docking of the brake clamping structure, reduces the possibility that the clamping extrusion force generated on the brake clamping docking groove 65 and the clamping docking joint 64 when the clamping structure is clamped is transmitted to the moving template, causing deformation of the moving template structure or deviation of the moving track, and when the brake is released from the docking state, under the limiting action of the clamping mounting cavity 21, the oil pressure in the clamping cylinder body 40 is reduced to the minimum and then drives the first gate seat 51 and the second gate seat 52 to move to the uppermost and lowermost positions in the clamping mounting cavity 21 respectively to complete the brake release, thereby improving the smoothness and reliability of the release work of the brake from the docking state, and cooperating with the lubrication groove 57 set on the first gate seat 51 and the second gate seat 52 to lubricate the contact surface, thereby reducing the possibility of the clamping and disengaging positions between the moving templates being stuck and mechanical damage caused by the failure of the brake clamping structure, thereby improving the use stability of the brake clamping device, improving the efficiency and stability of the clamping and releasing work of the die-casting machine during high-speed mold closing and mold separation, and improving the mold separation and closing efficiency of the die-casting machine.

[0059] See attached Fig.12 and attached Fig.13 As shown, lubrication grooves 57 are provided on the sides of the first gate seat 51 and the second gate seat 52. The lubrication grooves 57 can provide lubrication for the sides of the first gate seat 51 and the second gate seat 52, thereby improving the smoothness of the closing, clamping and separating and relaxing actions between the first gate seat 51 and the second gate seat 52 and the gate clamping docking groove 65 when the brake is clamped, thereby improving the reliability of the clamping action.

[0060] See attached Figure 1 To Attachment Figure 8As shown, the clamping piston rod 42 and the synchronous support shaft 50 are arranged on the movable template 10, and a group of annular uniformly distributed clamping docking cavities 15 are arranged in the movable template 10, and a clamping installation cavity 21 is arranged at the outer end of the clamping docking cavity 15, and a group of clamping guide holes 22 are arranged in the upper end wall of the clamping installation cavity 21, and the clamping guide holes 22 are slidably connected with the clamping piston rod 42 and the synchronous support shaft 50;

[0061] The lower end of the clamping oil cylinder body 40 is dynamically connected to the clamping piston rod 42, and the position of the clamping oil cylinder body 40 corresponds to the clamping guide hole 22. The first gate seat 51 and the second gate seat 52 are connected to each other in the upper and lower directions through surface contact and sliding in the side wall of the clamping installation cavity 21. The upper end surface of the second gate seat 52 is fixedly connected to the isolation limit block 53 by threading. The isolation limit block 53 can play an isolation and limit role between the first gate seat 51 and the second gate seat 52.

[0062] The four clamping installation chambers 21 are all located outside the clamping docking chamber 15. The upper end wall of the clamping installation chamber 21 is slidably connected to the synchronous bracket shaft 50 and the clamping piston rod 42 through the clamping guide hole 22. The clamping guide hole 22 can provide positioning and support when the clamping piston rod 42 and the docking end cover 20 are clamped together, thereby improving the clamping positioning and guiding accuracy of the middle plate clamping brake;

[0063] The left and right side walls of the clamping installation cavity 21 are planar structures, and the upper and lower side walls of the clamping installation cavity 21 are arc-shaped surfaces that match the upper end contour of the first gate seat 51 and the lower end contour of the second gate seat 52. The clamping installation cavity 21 can adapt to the sliding trajectory of the clamping and closing and the release and separation of the first gate seat 51 and the clamping piston rod 42, which can improve the clamping guide accuracy of the middle plate clamping brake and the accuracy of the clamping docking limit, and can improve the stability of the clamping of the middle plate clamping brake.

[0065] A group of evenly distributed clamping cylinder bodies 40 are provided on the movable template 10, a group of evenly distributed Corinthian column holes 12 and a clamping docking cavity 15 are provided in the movable template 10, the clamping docking joint 64 cooperates with the clamping docking cavity 15, a clamping installation cavity 21 is provided on the outer side of the clamping docking cavity 15, a group of clamping guide holes 22 are provided in the upper end wall of the clamping installation cavity 21, a clamping piston rod 42 and two left-right symmetrical synchronous bracket shafts 50 are slidably connected in the clamping guide holes 22, and the first gate seat 51 and the second gate seat 52 cooperate with the clamping gate docking groove 65 to fix the relative position between the rear template 60 and the movable template 10, so that the movable template 10 maintains a clamping cooperation state with the clamping docking joint 64 and the rear template 60 when moving on the guide track of the Corinthian column hole 12, thereby improving the stability of the clamping synchronization state between the rear template 60 and the movable template 10.

[0066] See attached Fig.12 and attached Fig.13 As shown, the lower end of the first gate seat 51 and the upper end of the second gate seat 52 are both provided with a gate tightening surface 58 that cooperates with the gate tightening docking groove 65;

[0067] When the two gate tightening surfaces 58 approach or separate the first gate seat 51 and the second gate seat 52 to hold and release, the two gate tightening surfaces 58 enter the gate tightening docking groove 65 to limit the position when holding and moving away from the gate tightening docking groove 65 to release. Under the isolation effect of the isolation limit block 53, the two gate tightening surfaces 58 can be prevented from entering the gate tightening docking groove 65 to cooperate with the limit position when holding. When the distance between the lower end surface of the first gate seat 51 and the upper end surface of the second gate seat 52 is too small, the first gate seat 51 and the second gate seat 52 can be prevented from being close to each other. When the extrusion pressure is too large during the process of clamping the gate docking groove 65, it is directly transmitted to the clamping docking head 64 and the gate docking groove 65. Under the cooperation of the isolation limit block 53, when the clamping extrusion pressure of the first gate seat 51 and the second gate seat 52 on the gate docking groove 65 is overloaded, part of the extrusion pressure can be shared within the range of elastic deformation of the extrusion pressure on the gate docking groove 65, which can protect the structural safety of the clamping docking head 64 and the gate docking groove 65 and improve the safety of use and the clamping reliability of the clamping structure.
