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.
[0032] Reference Figure 1 、 Figure 4The utility model provides an embodiment of a die-casting mold for automobile parts, comprising a machine table 1, wherein the four corners of the lower surface of the machine table 1 are fixedly connected with supporting legs for supporting the entire device, a feed port is provided on the upper surface of the machine table 1, a discharge port is provided on the right surface of the machine table 1, and a collection component is provided on the right surface of the machine table 1 for collecting the die-cast parts. The upper surface of the machine table 1 is fixedly connected with a support plate 3, and a hydraulic cylinder 4 is provided on the right surface of the support plate 3. The hydraulic cylinder 4 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The left end of the hydraulic cylinder 4 is fixedly connected with a punch 5. After the hydraulic cylinder 4 is started, it can drive the punch 5 to move horizontally. The right surface of the punch 5 is penetrated and fixedly connected with an injection pipe 6. The injection pipe 6 is connected to an external pressurizing system and can inject the die-casting raw material between the punch 5 and the die 9. The right surface of the machine table 1 is provided with an automatic demoulding mechanism, which can automatically eject the formed parts and reduce the demoulding time.
[0033] Reference Figure 1 、 Figure 4 The automatic demoulding mechanism includes a limit assembly and a positioning assembly. The automatic demoulding mechanism is provided with two groups, which are symmetrically distributed front and back with the center line of the punch 5. The positioning assembly includes a hollow tube 81. The machine 1 is elastically connected to the slide bar 83 through the connecting spring 82. The right surface of the hollow tube 81 is fixedly connected to the die 9. The die 9 and the punch 5 fit together. When the punch 5 and the die 9 are plugged in, they can maintain a seal. The right surface of the slide bar 83 is fixedly connected to the top plate 10. The top plate 10 can push the formed parts out, and the parts will fall into the feed In the mouth, the front surface of the slide rod 83 is fixedly connected to the slider 84, and the two will slide synchronously. The upper surface of the machine 1 is fixedly connected to the positioning plate 85. The limiting assembly includes a limiting plate 71. The left end of the lower surface of the limiting plate 71 is provided with a limiting groove 701. The front surface of the slider 84 is fixedly connected to the connecting block 72. The inner wall of the connecting block 72 is elastically connected to the limiting block 74 through a limiting spring 73. The upper surface of the positioning plate 85 is horizontal to the center line of the limiting block 74, and the positioning plate 85 can be squeezed to half of the limiting block 74.
[0034] Reference Figure 1 - Figure 3 The collection component includes a collection box 21. One end of a compression spring 23 is fixedly connected to the inner wall of the bottom end of the machine 1, and the other end of the compression spring 23 is fixedly connected to a buffer plate 22. When the buffer plate 22 moves downward, it will squeeze the compression spring 23 to generate a reaction force, and when the buffer plate 22 moves downward, it can achieve the effect of unloading force.
[0035] Reference Figure 1 、 Figure 4The output shaft of the hydraulic cylinder 4 passes through the left surface of the support plate 3 without causing any obstruction. One end of the connecting spring 82 is fixedly connected to the right surface of the machine table 1, and the other end of the connecting spring 82 is fixedly connected to the left surface of the slide bar 83. The slide bar 83 passes through and is slidably connected to the right surface of the hollow tube 81. When the slide bar 83 moves to the right, the connecting spring 82 is stretched to produce a reaction force. The left surface of the hollow tube 81 is fixedly connected to the right surface of the machine table 1. The hollow tube 81 can provide support for the die 9. The slide bar 83 passes through and is slidably connected to the left surface of the die 9. The outer wall of the top plate 10 and the inner wall of the die 9 fit together to prevent leakage of the die-casting raw material. The slider 84 passes through and is slidably connected to the front surface of the hollow tube 81. The right end of the rear surface of the limit plate 71 is fixedly connected to the punch. When the locking cam 73 is in the closed position, the locking cam 73 is in the closed position, and the locking cam 73 is in the closed position, so that the block 73 can slide in the closed position and slide in. When the locking cam 73 is in the closed position, the block 73 is in the closed position, and the locking cam 73 is in the closed position, so that the block 73 can slide in the closed position.
[0036] Reference Figure 1 - Figure 3 The collection box 21 is fixedly connected to the right surface of the machine 1, and the collection box 21 is located below the discharge port. The buffer plate 22 is slidably connected to the inner wall of the machine 1. The buffer plate 22 is arranged in an inclined shape, which can guide the parts.
[0037] Working principle: When this device is used, first start the hydraulic cylinder 4 to drive the punch 5 to move to the left. When the punch 5 and the die 9 are plugged in and fit together, close the hydraulic cylinder 4 and start the external pressurization system to inject the raw material from the injection tube 6 into the gap between the punch 5 and the die 9 and wait for a while to allow the raw material to cool and take shape.
[0038] When the punch 5 moves to the left, it will drive the limit plate 71 to move to the left. The limit plate 71 moving to the left will squeeze the inclined surface of the limit block 74. The inclined surface of the limit block 74 will be squeezed and move backward to squeeze the limit spring 73 to generate a reaction force, and will retract into the connecting block 72 to release the obstruction of the limit plate 71. When the punch 5 and the die 9 are plugged in and fitted, the limit block 74 will be aligned with the limit groove 701, and the reaction force of the limit spring 73 will push the limit block 74 to move forward and plug into the limit groove 701 to form a limit.
[0039] After the raw material is cooled and formed, the hydraulic cylinder 4 is started to drive the punch 5 to move to the right. The punch 5 moving to the right will drive the limit plate 71 to move to the right. The limit plate 71 will pull the limit block 74, the connecting block 72, and the slide bar 83 to move to the right. The slide bar 83 moving to the right will drive the top plate 10 to move to the right to eject the formed parts, and will stretch the connecting spring 82 to generate a reaction force. The inclined surface of the limit block 74 moving to the right will gradually be squeezed by the positioning plate 85, and gradually the limit block 74 will retract into the connecting block 72 and the limit groove 701 to release and limit the limit plate 71. After the limit between the limit block 74 and the connecting block 72 is released, the reaction force of the connecting spring 82 will pull the slide bar 83, the connecting block 72, and the limit block 74 to move to the left to the initial position.
[0040] The parts ejected and formed by the top plate 10 will fall into the feed port and eventually fall on the buffer plate 22. The impact force will cause the buffer plate 22 to move downward, and the downward moving buffer plate 22 will squeeze the compression spring 23. The reaction force of the compression spring 23 and the downward movement of the buffer plate 22 will alleviate the impact force, thereby achieving a buffering effect and avoiding damage to the parts. The parts will eventually slide out of the discharge port along the trajectory of the buffer plate 22 and enter the collection box 21 to be collected, completing the die-casting work.
[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
