Description

Technical Field

[0001] The invention relates to the technical field of automobile parts die-casting, and in particular to a high vacuum intelligent auxiliary die-casting system for automobile parts die-casting. Background Art

[0002] When the vacuum die-casting system is working, the chamber of the vacuum die-casting system is first evacuated to reach the required vacuum pressure. After the vacuum environment is established, the alloy raw materials required for die-casting are heated and melted, and finally die-casting is performed. That is, the current vacuum die-casting system is a production cycle at a time. This operation mode directly restricts its production efficiency. Subsequently, the field proposed to place the entire die-casting system directly in a vacuum environment, thereby realizing continuous production. For example, the vacuum die-casting system and its use method with application number 2015106996947, the raw materials for die-casting, the mold and the injection mechanism are all placed in the vacuum chamber, but the storage box is in a closed state. When the vacuum chamber is evacuated by a vacuum pump, the inside of the storage box cannot be evacuated, and it is difficult for the soup inside the storage box to effectively discharge the bubbles therein. If there are bubbles in the soup, during the die-casting process, pores will be generated inside the parts, which will greatly affect the key properties of the parts such as strength and density, making it difficult for the product quality to reach high standards. At the same time, in the material storage link, there is a lack of control over the soup temperature, the soup temperature is unstable, and cooling and agglomeration are prone to occur, which hinders the normal discharge of the discharge pipe, thereby affecting the continuity of the die-casting process and reducing production efficiency.

Specific implementation mode

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Usually, the components of the embodiments of the present invention described and shown here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0029] This embodiment proposes a high-vacuum intelligent auxiliary die-casting system for die-casting of automotive parts, as Figures 1 to 7 shown, which includes a moving template 10 and a fixed template 11 arranged inside the vacuum chamber body 1. Among them, the fixed template 11 is fixed inside the vacuum chamber body 1 through the fixed rods on both sides, and the moving template 10 is slidably and guidingly assembled inside the vacuum chamber body 1. A first cylinder 5 is also installed on the outer wall of the vacuum chamber body 1 corresponding to the position of the moving template 10, and the moving template 10 is driven by the first cylinder 5 to move relative to the fixed template 11. Of course, a ejection mechanism for separating the injection-molded part a is also provided inside the fixed template 11, and this part of the structure will not be elaborated here.

[0030] The entire die-casting system further includes a storage tank 8 disposed inside the vacuum chamber 1. The top of the storage tank 8 is fixedly connected to the inner wall of the top of the vacuum chamber 1, and the storage tank 8 is communicated with a feeding tank 2 installed outside the vacuum chamber 1. A plurality of arc-shaped notches 20 are annularly distributed on the outer wall of the storage tank 8 near its top and are communicated with the vacuum chamber 1. When the vacuum pump 4 at the top of the vacuum chamber 1 works, since the inside of the storage tank 8 is communicated with the vacuum chamber 1 at this time, a vacuum can also be formed inside the storage tank 8. In addition, if there are bubbles in the high-temperature molten metal, it will also affect the forming quality of the parts. Therefore, in this embodiment, the air in the high-temperature molten metal can also be pumped out by means of the vacuum pump 4. For this purpose, a stirring member is provided inside the storage tank 8, and the molten metal is continuously stirred by the stirring member to discharge the bubbles.

[0031] In addition, since the entire system realizes continuous production operation, it is required that the temperature of the molten metal inside the storage tank 8 is moderate and can be maintained at a constant temperature to avoid cooling and caking, which will affect subsequent injection. Therefore, an electric heating wire 17 (the electric heating wire 17 can adopt the existing known technology) is wrapped on the outer wall of the storage tank 8. The molten metal inside the storage tank 8 is insulated by the electric heating wire 17, and in cooperation with the stirring member, the temperature of each area of the molten metal is kept uniform.

[0032] A pouring tube 19 is horizontally communicated at the center of the fixed template 11. One end of the pouring tube 19 extends into the cavity of the moving template 10, and the other end is connected to an injection mechanism 9 provided on the inner wall of the vacuum chamber 1. A blanking tube 18 communicated at the bottom of the storage tank 8 extends downward to be communicated with the open end of the pouring tube 19.

[0033] Before die-casting, the feeding tank 2 outside the vacuum chamber 1 first injects high-temperature molten metal in a molten state into the storage tank 8. Subsequently, the valve at the bottom of the feeding tank 2 is closed to make the inside of the vacuum chamber 1 in a closed state. Then, the stirring member inside the storage tank 8 and the vacuum pump 4 outside the vacuum chamber 1 are started, and the vacuum degree inside the vacuum chamber 1 is controlled according to the quality requirements of the product. After the vacuum degree inside the vacuum chamber 1 reaches the preset value, the moving template 10 moves towards the fixed template 11 to close the mold. The valve at the bottom of the storage tank 8 is controlled to open, and the molten metal inside the storage tank 8 flows into the pouring tube 19. Then, the molten metal is injected into the forming mold through the injection mechanism 9 and waits for forming. After the part a is formed, it is taken out, and then the processing and forming of the next part are carried out until the molten metal inside the storage tank 8 is used up. Finally, the pressure inside the vacuum chamber 1 is restored to normal pressure by the vacuum pump 4, and the vacuum chamber 1 is opened, and all the formed parts a inside the vacuum chamber 1 are taken out.

[0034] Specifically, the stirring member in this embodiment includes a stirring shaft 15 distributed along the axis of the storage tank 8. A plurality of stirring blades 16 are annularly distributed on the circumferential surface of the stirring shaft 15. The top of the stirring shaft 15 extends upward through the outside of the vacuum chamber 1 and is connected to the output end of the first motor 3 fixed on the vacuum chamber 1.

[0035] Since the die-casting system in this embodiment can achieve continuous production operations, the blanking of the formed part a also needs to match the processing process. In view of this, a blanking plate 13 is further provided inside the vacuum chamber 1 in this embodiment. The blanking plate 13 is used to transfer the part a die-cast inside the fixed die plate 11 to the conveyor belt 12 inside the vacuum chamber 1.

[0036] As a preferred embodiment, the blanking plate 13 is made of a magnetic material. One end of it is connected to a connecting rod 23. The end of the connecting rod 23 is fixedly connected to a rotating shaft 22. A second motor 7 is installed on the outer wall of the vacuum chamber 1 corresponding to the axis of the rotating shaft 22. The second motor 7 is a stepping motor. The motor shaft of the second motor 7 penetrates into the vacuum chamber 1 and is fixedly connected to the rotating shaft 22. By driving the connecting rod 23 to rotate to the vertical direction by the second motor 7, the blanking plate 13 can pick up materials, and when the connecting rod 23 rotates to the horizontal state, materials are released. In the initial state, the connecting rod 23 is in the horizontal state, which does not affect the mold closing and die-casting of the moving die plate 10 and the fixed die plate 11. When the moving die plate 10 is opened, the second motor 7 drives the connecting rod 23 to rotate to the vertical state. At this time, the blanking plate 13 just corresponds to the part a inside the moving die plate 10. While the part a is ejected by the ejection mechanism inside the moving die plate 10, it is also adsorbed on the blanking plate 13. One end of the blanking plate 13 facing the connecting rod 23 is connected to a shaft rod. After the shaft rod extends into the connecting rod 23, it is connected to the output end of the third motor embedded in the connecting rod 23. After the part a is adsorbed and fixed on the blanking plate 13, while the second motor 7 drives the connecting rod 23 to rotate towards the conveyor belt 12, the third motor inside the connecting rod 23 also drives the blanking plate 13 to perform a 180° flip.

[0037] And a guiding plate 25 is arranged above the conveyor belt 12 inside the vacuum chamber 1. The guiding plate 25 is fixedly connected to the side wall inside the vacuum chamber 1 through a connecting plate. Before the connecting rod 23 rotates to the horizontal state, the blanking plate 13 first completes a 180° flip. When the connecting rod 23 rotates to the horizontal state, the blanking plate 13 just fits with the guiding plate 25.

[0038] Since the part a is adsorbed on the material taking plate 13, an external force is required to detach it from the material taking plate 13 and drop it onto the conveyor belt 12. Based on this requirement, in this embodiment, through holes 21 with the same specifications are provided in a penetrating manner at the centers of the material taking plate 13 and the guiding plate 25. A second cylinder 6 is installed on the outer wall of the vacuum chamber body 1 corresponding to the center of the guiding plate 25. After the piston rod of the second cylinder 6 extends into the vacuum chamber body 1, it can sequentially penetrate through the guiding plate 25 and the material taking plate 13. When the connecting rod 23 rotates to the horizontal state, the second cylinder 6 starts to work, and its piston rod passes through the guiding plate 25 and the material taking plate 13 and acts on the part a to make it detach from the material taking plate 13, and then it drops onto the conveyor belt 12 under the action of gravity.

[0039] As the part a is continuously die-cast and formed, the parts a placed on the conveyor belt 12 need to be continuously conveyed forward, otherwise accumulation will occur. However, the conveyor belt 12 in this embodiment is not provided with a corresponding power drive, but is directly driven by the work of the second cylinder 6 to periodically convey forward a fixed distance. That is, during the process of the piston rod of the second cylinder 6 driving the part a to detach from the material taking plate 13, the conveyor belt 12 is in the forward conveying state, thereby providing a placement space for each part a on the conveyor belt 12. Specifically, a plurality of groups of limiting members 14 are evenly distributed on the belt surface of the conveyor belt 12. Two limiting members 14 in each group are distributed at the edges in the width direction of the conveyor belt 12. A push plate 24 is fixedly sleeved on the piston rod of the second cylinder 6. When the piston rod of the second cylinder 6 extends, the push plate 24 contacts the limiting member 14 and the two form a clamping connection. At this time, the conveyor belt 12 rotates and conveys forward under the action of the limiting member 14. When the piston rod of the second cylinder 6 retracts, the push plate 24 and the limiting member 14 form a sliding fit, that is, the push plate 24 can slide over the top of the limiting member 14, and at this time the conveyor belt 12 remains stationary.

[0040] Specifically, the limiting member 14 in the above embodiment includes a fixed seat 141 fixed on the conveyor belt 12. Connecting seats 143 are fixed on both sides of the fixed seat 141 near its middle. A blocking plate 142 is arranged on the side of the fixed seat 141 facing the push plate 24. The bottom of the blocking plate 142 is hinged to the connecting seat 143, and a torsion spring is installed at the hinge between the two. The torsion spring is used to keep the blocking plate 142 in a vertical state all the time. A part of the blocking plate 142 protrudes above the top of the fixed seat 141, and the bottom of the push plate 24 extends downward to be flush with the top of the fixed seat 141. In the initial state, the piston rod of the second cylinder 6 is located at the through hole 21 of the guide plate 25, and at this time the push plate 24 is in contact with the top of the fixed seat 141 on one set of limiting members 14. When the piston rod of the second cylinder 6 extends, the forward conveying distance of the conveyor belt 12 is controlled by controlling the extending length of the piston rod. Let the distance between every two adjacent sets of limiting members 14 be D1, and the extending length of the piston rod be L, then L = 2 * D1. In this way, the extending length of the piston rod is long enough to ensure that the part a can smoothly separate from 13. And during the process of the piston rod extending by a length of D1, the conveyor belt 12 remains stationary at this time. When the push plate 24 contacts the blocking plate 142 on the next limiting member 14, the part a has already fallen onto the conveyor belt 12 at this time, and the conveyor belt 12 starts to convey forward under the action of the limiting member 14, so as to create space for the next part a. When the piston rod of the second cylinder 6 retracts, the push plate 24 contacts the upper area of the blocking plate 142, thus driving the blocking plate 142 to rotate relative to the fixed seat 141. At this time, the conveyor belt 12 does not rotate. When the push plate 24 passes over the limiting member 14, the blocking plate 142 resets under the action of the torsion spring.

[0041] It should be further noted that the material taking plate 13 is integrally square. In order to avoid interference between the material taking plate 13 and the limiting member 14 when it rotates to the horizontal state, in this embodiment, the distance between the two limiting members 14 in each group needs to be greater than the length of the material taking plate 13, and the material taking plate 13 is exactly in the middle position between the two limiting members 14.

[0042] Of course, as a preferred embodiment, in order to increase the storage capacity of part a inside the vacuum chamber 1 and enable the entire system to continuously complete the production of more part a within one vacuum cycle as much as possible, two conveyor belts 12 can be arranged inside the vacuum chamber 1 (correspondingly, two sets of second cylinders 6 and guide plates 25 are also arranged). The two conveyor belts 12 are symmetrically distributed inside the vacuum chamber 1 with the rotating shaft 22 as the center. During specific operation, the second motor 7 drives the rotating shaft 22 to rotate clockwise by 90° first, causing part a to fall onto one side of the conveyor belt 12. After the next material taking, the second motor 7 drives the rotating shaft 22 to rotate counterclockwise by 90°, causing part a to fall onto the other side of the conveyor belt 12. This cycle repeats, which can double the storage capacity of part a inside the vacuum chamber 1, reduce the frequency of opening the vacuum chamber 1 and re-pumping vacuum, and thus play a positive role in promoting production efficiency.
