Description

Technical Field

[0001] The invention relates to the technical field of mold manufacturing, and in particular to an anti-collision structure of a die-casting mold. Background Art

[0002] As an efficient metal forming method, die casting is widely used in many fields such as automobile, electronics, aerospace, etc. The quality and reliability of die casting molds are directly related to the production efficiency, quality and economic benefits of the product. Among the many parts of the die casting mold, the slider and the ejector play a vital role.

[0003] The slider is used to form the lateral structure of the product in the die-casting mold. When the mold is closed, the slider moves inward to participate in the molding, and when the mold is opened, the slider moves outward to separate from the product. The ejector is responsible for ejecting the product from the mold after the die-casting is completed to ensure that the product is smoothly demolded. In the actual production process, the pre-reset function of the ejector under the slider is one of the key links to ensure the normal operation of the mold. However, the common die-casting molds currently have serious safety hazards, that is, the pre-reset mechanism of the ejector under the slider is prone to failure. Once the pre-reset fails, the ejector is not restored to its position before the mold is closed, which will cause the ejector and the slider to collide during the mold closing process. This collision will not only damage the ejector, but more seriously, it may damage the slider, causing the slider to be scrapped. As an important component of the die-casting mold, the slider has a complex structure and high manufacturing cost. Once scrapped, it will greatly increase the production cost, while causing production stagnation and seriously affecting the production progress. Summary of the invention

When die-casting products with complex shapes, the ejection and reset timing of each ejector can be accurately controlled according to the demoulding requirements of different parts of the product, so as to achieve more sophisticated demoulding operations. At the same time, this connection method enhances the stability of the overall structure of the ejector, so that the ejector can maintain good parallelism and synchronization during the ejection and reset process, avoiding deformation or damage of the ejector due to uneven force, and further improving the reliability of the anti-collision structure.

The detection piece includes a detection block, and the detection block is provided with a through hole for the push rod to pass through. The push rod passes through the through hole, and the positioning block contacts the detection block. A force sensor is provided in the detection block. The detection piece adopts a combined structure of the detection block, the through hole and the force sensor, which improves the accuracy and reliability of the detection of push rod fracture. The through hole on the detection block provides a channel for the push rod to pass through without affecting the normal movement of the push rod. The push rod passes through the through hole, so that the positioning block contacts the detection block, and the force sensor can measure the force transmitted by the push rod in real time. This direct contact detection method can quickly and accurately sense subtle changes in the stress of the push rod. When the push rod breaks, the stress condition of the push rod will change significantly.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention connects the slider and the ejector through a control member, thereby realizing synchronous operation of the slider and the ejector. When the slider moves outward, the control member drives the ejector to eject the ejector rod, thereby completing the ejection action of the slag bag.

A detection piece is set on the ejector pin, and the force sensor in the detection block can detect the force of the ejector pin in real time. When the ejector pin breaks, its force will change significantly, and the force sensor can detect the change in time to determine whether the ejector pin is broken. If the ejector pin is detected to be broken, the movement of the slider can be stopped in time to avoid collision between the slider and the broken ejector pin, further improving the safety of the die-casting mold.

The ejector 7 is arranged on the movable mold frame 3, and its ejector rod 73 is in the movable mold cavity block 4. A detection member 74 for detecting whether the ejector rod 73 is broken is provided at one end of the ejector rod 73 away from the movable mold frame 3. The slider member is connected to the ejector 7 through the control member 8 to drive the ejector 7 and the slider member to run synchronously.

[0024] The ejector 7 includes an upper ejector plate 71 and a lower ejector plate 72, and a plurality of ejector rods 73 are provided. One end of the plurality of ejector rods 73 is arranged between the upper ejector plate 71 and the lower ejector plate 72, and the lower ejector plate 72 is connected to the control member 8. The ejector 7 adopts a structural design in which the upper ejector plate 71 and the lower ejector plate 72 cooperate with the plurality of ejector rods 73, thereby enhancing the stability and reliability of the ejection action. The plurality of ejector rods 73 act simultaneously, and can eject the slag bag more evenly, thereby avoiding the problems of uneven force and unstable ejection that may occur when a single ejector rod 73 is ejected, thereby ensuring that the slag bag can be demolded smoothly and improving the molding quality of the product.

[0025] The slider member includes a sliding block 1 5 and a sliding block 2 6. There are two sliding blocks 1 5 and two sliding blocks 2 6. The two sliding blocks 1 5 are respectively arranged on the left and right sides of the movable mold cavity block 4, and the two sliding blocks 2 6 are respectively arranged on the upper and lower sides of the movable mold cavity block 4. The two sliding blocks 1 5 and the two sliding blocks 2 6 are connected to the ejector 7 through a control member 8.

[0026] The control member 8 includes a connecting plate 81, a control rotating block 82 and a positioning plate 83. The positioning plate 83 is installed on the movable mold frame 3. The control rotating block 82 is rotatably arranged on the positioning plate 83 through a rotating rod 84. The two ends of the control rotating block 82 are respectively connected to the connecting plate 81 and the control block 85. The control block 85 is movably connected to the connecting plate 2 86. The connecting plate 2 86 is connected to the lower top plate 72. The lower top plate 72 is provided with a mounting groove 721. The connecting plate 2 86 is installed in the mounting groove 721. The connecting plate 1 81 is connected to the corresponding sliding block 1 5 or sliding block 2 6. The specific structural design of the control member 8 includes the corresponding connecting plate 81, the control rotating block 82, the positioning plate 83, the control block 85 and the connecting plate 2 86. The mutual cooperation provides a reliable way for power transmission between the slider and the ejector 7. The positioning plate 83 is installed on the movable mold frame 3 to provide a stable support and rotation basis for the control rotating block 82, ensuring the accuracy and stability of the rotation of the control rotating block 82. The two ends of the control rotating block 82 are respectively connected to the connecting plate 1 81 and the control block 85, which can effectively transmit the movement of the slider to the ejector 7. When the slider moves, the control rotating block 82 is driven to rotate by the connecting plate 1 81, and then the control block 85 and the connecting plate 2 86 drive the lower ejector plate 72 to realize the ejection and reset of the ejector rod 73. This precise transmission structure ensures the high synchronization of the movement of the slider and the ejector rod 73, greatly reducing the probability of collision.

[0027] A rotating end 821 is provided on the control rotating block 82, and a connecting end 1 822 and a connecting end 2 823 which are integral therewith are provided on the rotating end 821, and a connecting hole 824 is provided on the connecting end 1 822. A connecting rod 811 is provided on one end of the connecting plate 1 81 which is connected to the control rotating block 82, and the connecting rod 811 is located in the connecting hole 824. The design of the rotating end 821, the connecting end 1 822 and the connecting hole 824 on the control rotating block 82, and the coordination between the connecting rod 811 and the connecting hole 824 on the connecting plate 1 81 optimize the power transmission process of the control member 8. The movement of the connecting rod 811 in the connecting hole 824 enables the connecting plate 1 81 to flexibly drive the control rotating block 82 to rotate, and at the same time, the angle and direction of rotation are precisely controlled. This connection method not only ensures the high efficiency of power transmission, but also can absorb the impact and vibration during the movement to a certain extent, reduce the wear between components, and extend the service life of the mold.

[0028] The second connection end 823 is provided with a plurality of movable holes 825, in which a plug rod 851 is movably provided, and a control block 85 is provided at one end of the plug rod 851 away from the second connection end 823, and a hinged end 861 is provided on the second connection plate 86, and the control block 85 is hinged to the hinged end 861. The design of the movable hole 825 on the second connection end 823, the plug rod 851, the control block 85 and the hinged end 861 of the second connection plate 86 provides more flexibility and adjustment space for the movement of the control member 8, and the plug rod 851 in the movable hole 825 is provided. The movable connection allows the control block 85 to move within a certain range, so as to better adapt to the position changes of the slider and the push rod 73 during the movement. The hinged connection between the control block 85 and the connecting plate 86 can accurately transmit the movement of the control block 85 to the connecting plate 86, thereby driving the lower ejector plate 72 and the push rod 73 to move. This design can fine-tune the movement of the push rod 73 without affecting the overall transmission effect, ensuring that the push rod 73 maintains a safe distance from the slider during the ejection and resetting process to avoid collision.

[0029] The upper top plate 71 and the lower top plate 72 are both composed of a plate 1 711, a plate 2 712 and a plate 3 713. The control transfer blocks 82 on the two sliding blocks 1 5 are respectively connected to the two ends of the plate 1 711, and the control transfer blocks 82 on the two sliding blocks 2 6 are respectively connected to the two plates 712 and the three plates 713. The upper top plate 71 and the lower top plate 72 are composed of a plate 1 711, a plate 2 712 and a plate 3 713, and the control transfer blocks 82 on different sliders are connected to different plates. This structural design further refines the connection relationship between the ejector 7 and the slider, and improves the accuracy of motion control. The control transfer blocks 82 on the two sliding blocks 1 5 are respectively connected to the two ends of the plate 1 711. The two ends are connected, and the control rotating blocks 82 on the two sliding blocks 6 are respectively connected to the plate 2 712 and the plate 3 713, so that the sliders in different directions can independently and cooperatively control the movement of the ejector 7. When die-casting products with complex shapes, the ejection and reset timing of each ejector rod 73 can be accurately controlled according to the demoulding requirements of different parts of the product, so as to achieve more sophisticated demoulding operations. At the same time, this connection method enhances the stability of the overall structure of the ejector 7, so that during the ejection and reset process, the ejector rod 73 can maintain good parallelism and synchronization, avoiding deformation or damage of the ejector rod 73 due to uneven force, and further improving the reliability of the anti-collision structure.

[0030] A positioning block 731 is provided on the push rod 73, and a detection piece 74 for detecting the fracture of the push rod 73 is provided at one end of the push rod 73 close to the positioning block 731. The detection piece 74 is arranged between the upper top plate 71 and the lower top plate 72. The positioning block 731 is provided on the push rod 73, and the detection piece 74 is arranged close to one end of the positioning block 731 and between the upper top plate 71 and the lower top plate 72, so that the installation position and detection effect of the detection piece 74 are optimized. The setting of the positioning block 731 provides a stable reference point for the detection piece 74, so that the detection piece 74 can more accurately detect the force condition and movement state of the push rod 73. The detection piece 74 includes a detection block 741, and a through hole 742 is provided on the detection block 741 for the push rod 73 to pass through. The push rod 73 passes through the through hole 742, and the positioning block 731 contacts the detection block 741. A force sensor is provided in the detection block 741 743, the detection member 74 adopts a combined structure of a detection block 741, a through hole 742 and a force sensor 743, which improves the accuracy and reliability of the detection of the fracture of the push rod 73. The through hole 742 on the detection block 741 provides a passage for the push rod 73 to pass through without affecting the normal movement of the push rod 73. The push rod 73 passes through the through hole 742, so that the positioning block 731 contacts the detection block 741, and the force sensor 743 can measure the force transmitted by the push rod 73 in real time. This direct contact detection method can quickly and accurately sense slight changes in the force on the push rod 73. When the push rod 73 breaks, the force condition of the push rod 73 will change significantly. The force sensor 743 can detect this change in time and transmit the signal to the external control system, which then controls the alarm to sound and stops the movement of the slider.

[0031] The movable mold frame 3 is provided with a limit block 32 and a support column 31 corresponding to the plate 1 711, the plate 2 712 and the plate 3 713 respectively. The plate 1 711, the plate 2 712 and the plate 3 713 are all provided with a limit hole and a guide hole. The plate 1 711, the plate 2 712 and the plate 3 713 are movably arranged on the corresponding limit block 32 and the support column 31 through the limit hole and the guide hole. The upper limit block 32 and the support column 31 of the movable mold frame 3 cooperate with the upper limit hole and the guide hole of the plate 1 711, the plate 2 712 and the plate 3 713 to eject the parts. The movement of 7 plays a precise limiting role. During the ejection and resetting process of the ejector 7, the existence of the limit block 32 and the limit hole ensures that the plate 1 711, the plate 2 712 and the plate 3 713 can only move on the predetermined track to prevent the ejector 7 from deflecting or shaking. A mounting plate 33 is provided on the side of the movable mold frame 3 away from the movable mold cavity block 4. A lubricating mechanism 34 for lubricating the ejector rod 73 with lubricating oil is provided on the mounting plate 33. The lubricating mechanism 34 is an existing commonly used lubricating oil application method, which will not be described in detail here.

[0032] The movable mold cavity block 4 is provided with an ejection hole 41 for the ejector pin 73 to be inserted. The ejector pin 73 is in the ejection hole 41. The end of the ejector pin 73 is at a certain distance from the ejection end of the ejection hole 41 on the movable mold cavity block 4. The certain distance is maintained to prevent the ejector pin 73 from colliding with the sliding block 1 5 and the sliding block 2 6 during the ejection process. The distance between the end of the ejector pin 73 and the ejection end of the ejection hole 41 is essentially the "effective stroke redundancy" of the ejector pin 73. The ejector pin 73 needs to fill this distance first during ejection to ensure that the sliding block 1 5 and the sliding block 2 6 are completely separated before starting to contact the slag bag, thereby preventing the ejector pin 73 from colliding with the sliding block 1 5 and the sliding block 2 6.

[0033] When the present invention is in use, after the injection molding is completed, when the sliding block 1 5 and the sliding block 2 6 move outward in sequence, the sliding block 1 5 and the sliding block 2 6 will drive the corresponding connecting plate 1 81 connected thereto to move outward. Taking the sliding block 1 5 as an example, when the sliding block 1 5 moves outward, it drives the connecting plate 1 81 connected thereto to move outward together. The connecting rod 811 on the connecting plate 1 81 pushes the connecting end 1 822, so that the control rotating block 82 rotates on the positioning plate 83 with the rotating end 821 as the turning point. When the control rotating block 82 rotates, the plug rod 851 of the connecting end 2 823 drives the control block 85 to move. The control block 85 then drives the connecting plate 2 86 to move through the hinged end 861, thereby driving the lower top plate 72 connected thereto to move. The lower ejector plate 72 drives the upper ejector plate 71 to move, and then drives the multiple ejector rods 73 connected thereto to move, and the multiple ejector rods 73 eject the slag bag. The working principle of the sliding block 2 6 is similar to that of the sliding block 1 5. The synchronous ejection of the ejector rod 73 is achieved through the transmission of the control member 8. When the ejector rod 73 is ejected, the ejector rod 73 will be pushed out only after the sliding block 1 5 and the sliding block 2 6 are moved away, which can avoid the risk of ejector rod 73 being ejected and colliding with the sliding block 1 5 or the sliding block 2 6 before it is moved away. When the sliding block 1 5 and the sliding block 2 6 move and reset, the corresponding ejector rod 73 is driven to reset synchronously through the corresponding control member 8, which effectively avoids the collision of the ejector rod 73 with the slider due to the failure to reset. When the push rod 73 is pulled to reset, the detection member 74 monitors the push rod 73 in real time, and the positioning block 731 on the push rod 73 contacts the detection block 741. When the push rod 73 works normally, the force detected by the force sensor 743 is within the normal range; if the push rod 73 breaks, the friction force and the volume of the push rod 73 will decrease when it is pulled due to the shortening of the length of the push rod 73, and the force detected by the force sensor 743 will change, and the force condition of the push rod 73 will suddenly change. After the force sensor 743 detects the abnormal change in force, it transmits a signal to the external control system, and the control system can promptly control the entire slider to stop moving to avoid collision, and the alarm light reminds the staff that the push rod 73 is broken and needs to be repaired.
