Description

Technical Field

[0001] The invention relates to the technical field of die casting moulds, and in particular to a die casting mould for producing automobile parts. Background Art

[0002] The die-casting mold hydraulically injects molten metal into the mold under pressure and cools it into shape. After the mold is opened, a solid metal casting can be obtained. In order to reduce the production quantity of automobile parts and improve the efficiency of automobile production, the original multiple parts can be die-cast as a whole into a complete casting.

[0003] Existing die-casting molds usually use a water-cooling cycle when cooling. Therefore, after the casting is cooled and formed, coolant still remains inside the mold. However, before injecting casting liquid into the mold, the mold needs to be preheated to increase the speed at which the casting liquid enters the mold. The presence of coolant will affect the mold preheating speed, and thus affect the efficiency of automotive parts casting. A layer of scale is easily formed inside the water-cooling channel after long-term use, and the scale accumulates thicker and thicker. The presence of scale will affect the heat conduction effect of the mold, and then affect the speed of heat dissipation of the water-cooling cycle, thereby resulting in slow cooling and forming of the casting.

[0054] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0055] Example: See Figure 1 - Figure 7 , a die-casting mold for producing automobile parts, comprising a base 1, a fixed mold 2 and a movable mold 3, and also comprising:

[0056] There are two fixed seats 4, which are respectively installed on the top of the base 1, and the fixed mold 2 is installed on the outer wall of the right fixed seat 4. The fixed mold 2 is connected to the injection pipe 41;

[0057] A slide seat 5 is arranged between two fixed seats 4, and the movable mold 3 is installed on the outer wall of the slide seat 5 close to the fixed mold 2;

[0058] A hydraulic mechanism is installed on the fixed seat 4 on the left side, and is used to drive the slide 5 and the movable mold 3 to move. The hydraulic mechanism includes a plurality of guide rods 6 fixedly connected between the two fixed seats 4 and a plurality of hydraulic cylinders 7 installed inside the left fixed seat 4; the slide 5 is slidably sleeved on the outside of the plurality of guide rods 6; and the extended ends of the plurality of hydraulic cylinders 7 are all fixedly connected to the outer wall of the slide 5;

[0059] The fixed mold 2 and the movable mold 3 are preheated by the heating tubes inside them so as to increase the speed of subsequent casting liquid flowing inside them. The hydraulic cylinder 7 is controlled to extend to drive the slide 5 to slide rightward along the outside of each guide rod 6, so that the movable mold 3 and the fixed mold 2 are merged together. After the air inside the mold cavities of the fixed mold 2 and the movable mold 3 is exhausted, the casting liquid is injected into the cavities of the fixed mold 2 and the movable mold 3 through the injection pipe 41.

[0060] After the casting liquid is cooled and formed, the hydraulic cylinder 7 is controlled to shorten, and the slide 5 and the movable mold 3 are moved to the left and separated from the fixed mold 2.

[0061] The exhaust mechanism is installed on the right side fixed seat 4, and is used to exhaust the air in the cavities of the two cavities after the movable mold 3 and the fixed mold 2 are molded together. The exhaust mechanism includes a control cylinder 8 installed inside the right side fixed seat 4, a partition 9 fixedly connected to the inside of the control cylinder 8, and an air guide tube 10 installed on the outer wall of one side of the control cylinder 8; a first piston 11 is installed inside the control cylinder 8, a sliding rod 12 is fixedly connected to the bottom of the first piston 11, and the sliding rod 12 slides through the partition 9; a second piston 13 is fixedly connected to the bottom end of the sliding rod 12, and one end of the air guide tube 10 Located between the partition 9 and the second piston 13; the other end of the air guide pipe 10 is connected to the inner cavity of the fixed mold 2, and a first solenoid valve 14 is installed on the air guide pipe 10. A first exhaust hole is opened on the outer wall of the other side of the control cylinder 8, and a second exhaust hole is opened at the bottom of the control cylinder 8. The first exhaust hole is located above the partition 9; the outer sleeve of the sliding rod 12 is provided with a first spring 15, the top end of the first spring 15 is fixedly connected to the bottom of the first piston 11, and the bottom end of the first spring 15 is fixedly connected to the top of the partition 9; the control cylinder 8 is connected to the cooling and cleaning mechanism;

[0062] After the fixed mold 2 and the movable mold 3 are combined together, the second solenoid valve 21 and the third solenoid valve 22 are controlled to be in a closed state, and the first solenoid valve 14, the fourth solenoid valve 24 and the fifth solenoid valve 25 are in an open state. High-pressure gas is filled into the control cylinder 8 through the high-pressure air pipe 23 and the four-way 19. After the high-pressure gas enters the control cylinder 8, the first piston 11 is driven to move downward, and the first spring 15 is compressed accordingly. At the same time, the second piston 13 is driven to move downward through the slide rod 12. In this process, the gas inside the fixed mold 2 and the movable mold 3 is sucked into the control cylinder 8 through the air guide pipe 10, and then the first solenoid valve 14, the fourth solenoid valve 24 and the fifth solenoid valve 25 are controlled to be closed, thereby avoiding the problem of air holes in the casting after the air inside the mold cavity is difficult to be discharged normally.

[0063] A combined cooling mechanism is installed on the fixed mold 2 and the movable mold 3, and is used to cool the fixed mold 2 and the movable mold 3 after the fixed mold 2 and the movable mold 3 are molded and injected. The combined cooling mechanism includes a first cooling channel 16 installed inside the fixed mold 2, a second cooling channel 17 installed inside the movable mold 3, and a drainage pipe 18 installed inside the fixed mold 2; the input end of the first cooling channel 16 extends to the outside of the fixed mold 2, and is connected to a water supply pipe 20 through a cross 19, and a second solenoid valve 21 and a third solenoid valve 22 are installed on the first cooling channel 16 and the water supply pipe 20, respectively, and the output end of the first cooling channel 16 extends to the outside of the fixed mold 2; the output end of the second cooling channel 17 extends to the outside of the movable mold 3, and is adapted to the input end of the drainage pipe 18, and the input end of the second cooling channel 17 is adapted to the output end of the first cooling channel 16; the output end of the drainage pipe 18 extends to the outside of the fixed mold 2;

[0064] When the movable mold 3 moves to the right and closes with the fixed mold 2, the output end of the first cooling channel 16 will be inserted into the input end of the second cooling channel 17, and the output end of the second cooling channel 17 will be inserted into the input end of the drain pipe 18, so that the first cooling channel 16, the second cooling channel 17 and the drain pipe 18 are connected together. At this time, the first solenoid valve 14, the fourth solenoid valve 24 and the fifth solenoid valve 25 are controlled to be in a closed state, and the second solenoid valve 21 and the third solenoid valve 22 are both in an open state. Coolant is injected into the first cooling channel 16 through the upper water pipe 20 and the four-way 19. The coolant passes through the first cooling channel 16, the second cooling channel 17 and the drain pipe 18 in turn, and circulates in this way to cool the casting liquid inside the fixed mold 2 and the movable mold 3 to obtain a formed casting.

[0065] A cooling and cleaning mechanism is installed on the fixed seat 4 on the right side and is connected to the combined cooling mechanism, and is used for high-pressure cleaning of the coolant remaining after the combined cooling mechanism is used.

[0066] After the molded casting is obtained, the fourth solenoid valve 24 and the second solenoid valve 21 are first controlled to be in an open state, and the third solenoid valve 22 and the fifth solenoid valve 25 are in a closed state. Then, high-pressure gas is filled into the first cooling channel 16 through the high-pressure gas pipe 23 and the four-way 19. The high-pressure gas passes through the first cooling channel 16, the second cooling channel 17 and the drain pipe 18 in sequence, and the coolant remaining in the first cooling channel 16, the second cooling channel 17 and the drain pipe 18 is completely discharged to prevent the coolant from remaining in the first cooling channel 16, the second cooling channel 17 and the drain pipe 18, which affects the subsequent preheating speed of the fixed mold 2 and the movable mold 3. In addition, the friction between the high-pressure gas and the inner walls of the first cooling channel 16 and the second cooling channel 17 can prevent the formation of a scale layer on the inner walls of the first cooling channel 16 and the second cooling channel 17, which affects the internal cooling effect of the fixed mold 2 and the movable mold 3.

[0067] The automatic discharging mechanism is installed inside the base 1 and connected to the slide 5, and is used to automatically discharge the die-casting castings. The automatic discharging mechanism includes a transmission shaft 26 rotatably connected to the inner wall of the base 1, a receiving plate 27 fixedly sleeved on the outside of the transmission shaft 26, a linkage component for driving the transmission shaft 26 to rotate, and a demoulding component installed on the slide 5. The friction between the transmission shaft 26 and the inner wall of the base 1 is large, and it will not rotate easily. It will only rotate when the rack 32 and the gear 30 are meshed. The top of the receiving plate 27 is provided with a rubber buffer layer 28; the top of the base 1 is provided with a feed opening 29, which is located above the receiving plate 27; the linkage assembly includes a gear 30 fixedly sleeved on the outside of the transmission shaft 26, a linkage bar 31 fixedly connected to the bottom of the slide seat 5, and a rack 32 fixedly connected to one end of the linkage bar 31; the gear 30 is meshed with the rack 32; the top of the base 1 is provided with a slide groove 33, the linkage bar 31 is slidably connected to the inside of the slide groove 33, and the base 1 A conveyor 34 is provided at the bottom, and the conveyor 34 is located below the receiving plate 27. The demoulding assembly includes a plurality of first telescopic rods 35 fixedly connected to the outer wall of one side of the movable mold 3, a connecting plate 36 fixedly connected to the extended ends of the plurality of first telescopic rods 35, and a plurality of ejector pins 37 fixedly connected to the outer wall of one side of the connecting plate 36; a structural groove is provided inside the slide seat 5, and the first telescopic rods 35 and the connecting plate 36 are both located on the inner side of the structural groove; the other ends of the plurality of ejector pins 37 are all slidably extended to the inside of the movable mold 3; the first telescopic rods 35 A second spring 38 is sleeved on the outside, one end of the second spring 38 is fixedly connected to the outer wall of the connecting plate 36, and the other end of the second spring 38 is fixedly connected to the outer wall of the movable mold 3; a second telescopic rod 40 is installed inside the fixed seat 4 on the left, and a disc is fixedly connected to the extended end of the second telescopic rod 40, and a third spring 39 is sleeved on the outside of the second telescopic rod 40, one end of the third spring 39 is fixedly connected to the outer wall of the fixed seat 4 on the left, and the other end of the third spring 39 is fixedly connected to the outer wall of the disc, and the disc cooperates with the connecting plate 36;

[0068] After the casting is formed and the coolant in the two cooling channels is discharged, the slide 5 and the movable mold 3 are driven to move to the left, and the slide 5 drives the rack 32 to move synchronously through the linkage bar 31. When the connecting plate 36 abuts against the disc, since the elastic force of the second spring 38 is less than the elastic force of the third spring 39, the connecting plate 36 begins to stop moving, the first telescopic rod 35 contracts, and then the casting is ejected through the ejector pin 37, and the casting falls on the rubber buffer layer 28 at the top of the receiving plate 27. When the slide 5 moves to the left to the left side of the discharge port 29, the rack 32 begins to mesh with the gear 30, and when the slide 5 continues to move to the left, the gear 30 is meshed with the gear 30, driving the transmission shaft 26 to rotate 360°, and then driving the receiving plate 27 to flip 360°. In this process, the casting is transferred to the top of the conveyor 34 and directly transported away by the conveyor 34. There is no need for manual discharging or setting up robot discharging, which effectively reduces the processing cost.
