Description

Technical Field

[0001] The present disclosure relates to the technical field of die-casting molds, and particularly to a die-casting mold with a signal switch and a die-casting device for new energy vehicle parts. Background Art

[0002] Currently, after a die-casting mold with a core-pulling structure completes one die-casting, the core-pulling needle of the core-pulling structure is pulled away from the die-casting part under the drive of a hydraulic cylinder, and then the ejector rod of the ejecting structure ejects the die-casting part out of the cavity to complete the mold-opening action. Then, the ejector rod returns downward, and the core-pulling needle also returns to its original position, that is, back into the cavity, to complete the mold-closing action and prepare for the next die-casting.

[0003] However, the existing ejector rod structure is connected to the die-casting machine through threaded fasteners. Due to the fatigue fracture, damage of the threaded fasteners during long-term use and accidental detachment caused by improper human operation, the ejector rod cannot be normally reset in the mold-closing state, resulting in a collision between the core-pulling needle and the ejector rod when the core-pulling needle enters the cavity, causing damage to the core-pulling needle and the ejector rod, affecting the normal use of the die-casting mold, and thus affecting the production efficiency of the die-casting part.

The terms used in the description of this disclosure herein are only for the purpose of describing specific embodiments and are not intended to limit this disclosure. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0031] To better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below with specific embodiments:

[0032] As Figures 1 to 5As shown, a die-casting mold 10 with a signal switch in an embodiment includes a support frame body 100, a fixed mold assembly 400, a movable mold assembly 500, a core-pulling assembly 200, an ejection assembly 300, and a signal assembly 600; the movable mold assembly 500 is movably arranged between the support frame body 100 and the fixed mold assembly 400, the core-pulling assembly 200 includes an oil cylinder 210 and a core-pulling pin 220, the telescopic end of the oil cylinder 210 is connected to the core-pulling pin 220, the core-pulling pin 220 is slidably arranged in the movable mold assembly 500, the ejection assembly 300 includes a bottom plate 310 and an ejector rod 320, the ejector rod 320 is arranged at one end of the bottom plate 310, the other end of the bottom plate 310 is connected to a die-casting machine (not shown in the figure), the bottom plate 310 is movably arranged in the sliding groove 110 of the support frame body 100, and the ejector rod 320 is used to eject the die-casting part through the through hole of the movable mold assembly 500; the signal assembly 600 includes a signal switch 610 and a signal contact block 620, the signal switch 610 is arranged on the support frame body 100, the signal contact block 620 is arranged at the side end of the bottom plate 310, the signal switch 610 is used to start the oil cylinder 210 to drive the core-pulling pin 220 to enter the mold cavity when touching the signal contact block 620, and is used to stop the oil cylinder 210 when separating from the signal contact block 620.

[0033] It can be understood that since the movable mold assembly 500 is movably arranged between the support frame body 100 and the fixed mold assembly 400, the movable mold assembly 500 can be pressed against the fixed mold assembly 400 to ensure that the die-casting part is formed in the mold cavity between the movable mold assembly 500 and the fixed mold assembly 400. Since the bottom plate 310 is movably arranged in the sliding groove 110 of the support frame body 100, it is ensured that the bottom plate 310 drives the ejector rod 320 to move up and down in the sliding groove 110 under the action of the die-casting machine, so as to ensure that the ejector rod 320 can eject the die-casting part, thereby realizing the normal operation of ejecting the die-casting part in the open mold state of the fixed mold assembly 400 and the movable mold assembly 500, and further improving the production efficiency of the die-casting part.

[0034] Further, the output end of the signal switch 610 is used to connect to the signal input end of the die-casting machine, and the signal output end of the die-casting machine is used to connect to the start / stop input end of the oil cylinder 210. In this embodiment, by setting the signal assembly 600, when the movement of the bottom plate 310 drives the signal contact block 620 to touch the signal switch 610, the signal switch 610 sends a start feedback signal to the die-casting machine, reminding that the mold closing state of the fixed mold assembly 400 and the moving mold assembly 500 is normal. Then the die-casting machine sends the start feedback signal to the oil cylinder 210 to further start the oil cylinder 210 to drive the core-pulling pin 220 into the cavity. When the connection between the die-casting machine and the bottom plate 310 is disconnected, the bottom plate 310 cannot drive the ejector rod 320 to move, so that the signal contact block 620 cannot touch the signal switch 610. The signal switch 610 will generate a stop feedback signal, reminding that the mold closing state of the fixed mold assembly 400 and the moving mold assembly 500 is abnormal, and timely transmit the stop feedback information to the die-casting machine. Then the die-casting machine transmits the stop feedback information to the oil cylinder 210, and the oil cylinder 210 will stop running in time, avoiding the core-pulling pin 220 entering the cavity in the mold closing state, thereby realizing the automatic control of the start / stop of the oil cylinder 210 by the die-casting machine, preventing accidental collision between the core-pulling pin 220 and the ejector rod 320 in the mold closing state, realizing timely maintenance and repair of the die-casting mold, reducing the downtime, and thus improving the production efficiency of die-castings.

[0035] As Figure 1 , Figure 3 and Figure 4 shown, in one embodiment, the signal switch 610 includes a signal installation part 611 and a switch handle 612. The signal installation part 611 is detachably arranged on the support frame 100, and the switch handle 612 is movably arranged on the signal installation part 611. The switch handle 612 is used to touch the signal contact block 620. It can be understood that since the signal installation part 611 is detachably arranged on the support frame 100, when the signal installation part 611 is damaged, the operator can replace the signal switch 610 in time to ensure the normal operation of the die-casting mold. Since the switch handle 612 is movably arranged on the signal installation part 611, when the fixed mold assembly 400 and the moving mold assembly 500 are closed, the signal contact block 620 touches the switch handle 612 to ensure the normal opening of the signal installation part 611, so as to ensure that the signal installation part 611 can normally feedback the start / stop information, further ensure the normal operation of the die-casting mold, and thus improve the production efficiency of die-castings.

[0036] In one embodiment, the signal installation part 611 is provided with a transfer slot 611a. The switch handle 612 includes a touch part 612a and a movable part 612b. One end of the touch part 612a is connected to the movable part 612b, and the other end of the movable part 612b is connected to the signal installation part 611 through the transfer slot 611a. It can be understood that since one end of the movable part 612b is connected to the touch part 612a and the other end of the movable part 612b is connected to the signal installation part 611 through the transfer slot 611a, when the touch part 612a touches the signal contact block 620, the movable part 612b can drive the signal installation part 611 to be activated, and the signal installation part 611 will feedback information in time to ensure the normal progress of the mold closing state of the fixed mold assembly 400 and the movable mold assembly 500.

[0037] As Figure 4 shown, in one embodiment, the signal contact block 620 is formed with an inclined sliding surface 621. The inclined sliding surface 621 is arranged facing the switch handle 612 and is used to touch the switch handle 612. It can be understood that due to the inclined sliding surface 621 formed by the signal contact block 620, it is ensured that the contact area is increased when the signal contact block 620 collides with the switch handle 612, ensuring that the signal contact block 620 can effectively touch the switch handle 612 and realizing that the switch handle 612 sends a feedback signal in time after activating the signal switch 610.

[0038] In one embodiment, the die-casting mold 10 with a signal switch further includes a threaded fastener 700. The signal installation part 611 is provided with a mounting hole (not shown in the figure), and the threaded fastener 700 is connected to the support frame 100 through the mounting hole. It can be understood that on the one hand, the additional threaded fastener 700 ensures the easy disassembly and assembly of the signal installation part 611, enabling the signal switch 610 to be replaced in time when damaged. On the other hand, it ensures the firmness of the signal switch 610 installed on the support frame 100, ensuring that the signal contact block 620 is not easily displaced when touching the signal switch 610, thereby improving the accuracy of signal feedback.

[0039] In one embodiment, the core-pulling assembly 200 further includes a stroke slider 230. The stroke slider 230 is slidably arranged in a guide cavity (not shown in the figure) of the movable mold assembly 500. The telescopic rod 211 of the oil cylinder 210 is connected to one end of the stroke slider 230 through a guide hole of the movable mold assembly 500, and the other end of the stroke slider 230 is connected to the core-pulling pin 220. It can be understood that the stroke slider 230 provides stable support and guidance for the core-pulling pin 220. Driven by the telescopic rod 211 of the oil cylinder 210, the core-pulling pin 220 can move smoothly along a predetermined trajectory through the connection with the stroke slider 230, reducing the shaking and deviation during the core-pulling process, thereby ensuring the accuracy and stability of the core-pulling.

[0040] As Figure 2 andFigure 5 As shown, in one embodiment, the die-casting mold 10 with a signal switch also includes a telescopic support column 800, which is arranged at the bottom of the bottom plate 310, so that when the bottom plate 310 is driven by the die-casting machine, the telescopic support column 800 plays a role of buffering support for the bottom plate 310 when the bottom plate 310 is descending, thereby preventing the bottom plate 310 from detaching from the slide groove 110 due to the bottom plate 310 moving too fast.

[0041] like Figure 1 and Figure 3 As shown, in one of the embodiments, a limited stroke portion 120 is formed at the bottom of the sliding groove 110, and the bottom plate 310 is movably arranged on the limited stroke portion 120, so that when the bottom plate 310 moves in the sliding groove 110, the limited stroke portion 120 is used to limit the stroke of the bottom plate 310, thereby ensuring the limited stroke of the bottom plate 310 in the sliding groove 110, and cooperating with the telescopic support column 800 to ensure that the bottom plate 310 drives the ejector rod 320 to eject and reset the die-casting within an effective range, thereby preventing the bottom plate 310 from leaving the sliding groove 110, thereby improving the production efficiency and effect of the die-casting.

[0042] The present disclosure also provides a new energy vehicle parts die-casting device, comprising the die-casting mold 10 with a signal switch as described in any of the above embodiments.

[0043] In one of the embodiments, the die-casting device for new energy vehicle parts includes a connecting rod 900, and the base plate 310 is connected to the connecting end of the die-casting machine through the connecting rod 900, so that the die-casting machine drives the ejector rod 320 to move. In this embodiment, the base plate 310 and the die-casting machine are connected by the connecting rod 900. On the one hand, the die-casting machine and the base plate 310 are detachable, and the operator can maintain and replace the die-casting machine and the base plate 310 separately. On the other hand, it ensures that the die-casting machine can drive the base plate 310 to move up and down, thereby ensuring that the ejector rod 320 can effectively eject the die-casting.

[0044] Compared with the prior art, the present invention has at least the following advantages:

[0045] 1) The die-casting mold 10 with a signal switch disclosed in the present invention has a movable mold assembly 500 movably disposed between the support frame 100 and the fixed mold assembly 400, so that the movable mold assembly 500 can be pressed onto the fixed mold assembly 400, ensuring that the die-casting is formed in the cavity between the movable mold assembly 500 and the fixed mold assembly 400. Since the bottom plate 310 is movably disposed in the slide groove 110 of the support frame 100, it is ensured that the bottom plate 310 drives the ejector rod 320 to move up and down in the slide groove 110 under the action of the die-casting machine, so as to ensure that the ejector rod 320 can eject the die-casting, thereby realizing the normal operation of the fixed mold assembly 400 and the movable mold assembly 500 in the open mold state to eject the die-casting, thereby improving the production efficiency of the die-casting.

[0046] 2) The die-casting mold 10 with a signal switch according to the present disclosure, by setting a signal assembly 600, when the bottom plate 310 moves to drive the signal contact block 620 to touch the signal switch 610, the signal switch 610 sends a start feedback signal to the die-casting machine, reminding that the mold closing state of the fixed mold assembly 400 and the moving mold assembly 500 is normal. The die-casting machine then sends the start feedback signal to the oil cylinder 210 to further start the oil cylinder 210 to drive the core-pulling pin 220 into the cavity. When the connection between the die-casting machine and the bottom plate 310 is disconnected, the bottom plate 310 cannot drive the ejector rod 320 to move, so that the signal contact block 620 cannot touch the signal switch 610. The signal switch 610 will generate a stop feedback signal, reminding that the mold closing state of the fixed mold assembly 400 and the moving mold assembly 500 is abnormal, and timely transmit the stop feedback information to the die-casting machine. The die-casting machine then transmits the stop feedback information to the oil cylinder 210, and the oil cylinder 210 will stop running in time, avoiding the core-pulling pin 220 from entering the cavity in the mold closing state, thereby realizing the automatic control of the start and stop of the oil cylinder 210 by the die-casting machine, preventing accidental collision between the core-pulling pin 220 and the ejector rod 320 in the mold closing state, realizing timely maintenance and repair of the die-casting mold, reducing the downtime, and thus improving the production efficiency of die-castings.

[0047] The above embodiments only represent several implementation manners of the present disclosure, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
