Description

Technical Field

[0001] The present invention relates to the technical field of die-casting of metal products, and in particular to a die-casting device for metal products. Background Art

[0002] The production of various die-cast products, typically made of aluminum or aluminum alloys, is well known. The die-casting process essentially involves injecting liquid metal into the first part of a mold, closing the mold under pressure so that the liquid metal, forced by the closed mold, fills the mold cavity without entraining air. Pressure is maintained on the metal during solidification to ensure that any shrinkage cavities that may have formed are sealed and filled. The mold is then opened and the finished product is removed.

[0003] Existing die-casting equipment uses various methods to vent liquid metal when it is injected into the cavity, ensuring that the molten metal can effectively expel gas when injected into the mold, thereby improving the quality of the casting. For example, venting grooves are designed on the parting surface of the mold or other suitable locations. These grooves are very small, large enough to allow gas to pass through without causing the molten metal to overflow; or vent holes are set in key parts of the mold. These holes are usually connected to the exhaust system to allow gas to be discharged smoothly. However, this method has the following disadvantages:

[0004] 1. Depends on the exhaust design of the mold itself, and exhaust grooves or holes need to be reserved in the mold, which increases the design complexity and manufacturing difficulty of the mold;

[0005] 2. The exhaust effect is affected by many factors, such as mold temperature, pouring speed, etc., which may lead to unstable exhaust effect;

[0006] 3. The exhaust grooves or holes in the mold may wear out or become clogged after long-term use, affecting the exhaust effect and shortening the service life of the mold. Summary of the Invention

[0007] In order to overcome the disadvantage that the existing die-casting molding equipment relies on the exhaust design of the mold itself to exhaust the melt, which has a poor exhaust effect, the technical problem is to provide a die-casting molding equipment for metal products.

[0008] A die-casting forming equipment for metal products includes a base, a fixed mold, an injection tube, a movable mold, a guide rod, a hydraulic cylinder, a channel tube and a discharge tube. The fixed mold is connected to the left side of the top of the base, and guide rods are symmetrically connected to both sides of the fixed mold. The movable mold is slidably connected between the guide rods, and the movable mold contacts the top surface of the base. A hydraulic cylinder is installed on the left side of the base, and the channel tube is connected to the left side of the fixed mold. The piston of the hydraulic cylinder is slidably connected to the inside of the channel tube, and the discharge tube is connected to the left side of the top of the channel tube. The injection tube is connected through the fixed mold, and the channel tube is aligned with the injection tube. The forming equipment also includes a connecting tube, a blocking rod, an exhaust pipe, a closing assembly and a positioning assembly. The right side of the top of the channel tube is connected and connected to a connecting tube, a blocking rod is slidably connected to the connecting tube, the front side of the connecting tube is connected and connected to the exhaust pipe, a positioning assembly is provided on the connecting tube, and a closing assembly is provided on the fixed mold.

[0009] Optionally, the closing component includes a motor, a turntable and a closing piece. The motor is installed on the left side of the lower part of the fixed mold, and the turntable is connected to the motor output shaft. The turntable is located inside the fixed mold. The closing piece is slidably connected inside the fixed mold. A through hole is opened on the upper side of the closing piece. The closing piece is located between the channel tube and the injection molding tube. The diameter of the through hole is the same as that of the channel tube and the injection molding tube. A protrusion is provided on the upper end of the turntable, and the protrusion is slidably connected to the lower side of the closing piece.

[0010] Optionally, the positioning assembly includes a reset spring, a moving part, a support block, a clamping block and a compression spring. A reset spring is connected between the connecting tube and the blocking rod. A moving part is connected to the top of the closing part. The moving part presses against the upper end of the blocking rod. A support block is connected to the upper left side of the fixed mold. A clamping block is slidably connected to the support block. Multiple compression springs are evenly connected between the clamping block and the support block. A clamping slot is provided on the upper side of the blocking rod. The clamping block is engaged with the clamping slot. An inclined portion is provided on the upper right side of the clamping block, and the moving part contacts and engages with the inclined portion.

[0011] Optionally, it further includes a drainage pipe, a connecting frame and a collecting frame. The rear side of the connecting pipe is connected to and communicates with the drainage pipe. The lower end of the drainage pipe is connected to the connecting frame. The collecting frame is slidably connected to the connecting frame.

[0012] Optionally, the exhaust pipe is tilted upward and the drain pipe is tilted downward, so as to facilitate the rapid discharge of excess melt.

[0013] Optionally, a push rod is further included, and the fixed mold is symmetrically and slidingly connected with the push rod. Oblique grooves are provided on both sides of the closing piece, and the push rod is slidably connected to the oblique grooves.

[0014] Optionally, an electric push rod and a scraper are also included. The electric push rod is installed on the right side of the top of the channel tube, and the scraper is connected to the telescopic rod of the electric push rod. The size of the scraper fits the size of the channel in the discharge tube, and the two slide together.

[0015] Optionally, a dustproof plate and a buffer spring are also included. The dustproof plate is slidably connected to the upper side of the scraper, and a buffer spring is connected between the dustproof plate and the scraper. The size of the dustproof plate fits the size of the top surface of the discharge pipe.

[0016] The beneficial effects are: 1. Before the molten metal enters the cavity, the exhaust operation is performed in the channel tube through the cooperation of the piston and the exhaust pipe, which can significantly reduce the amount of gas entering the cavity, thereby reducing the formation of defects such as pores. Since most of the gas has been discharged at the channel tube stage, the exhaust demand inside the cavity is relatively reduced, thereby simplifying the mold design and reducing the number of exhaust slots or holes in the mold;

[0017] 2. By controlling the precise movement of the piston, a drain pipe is set at the channel pipe stage. If an error occurs during material feeding and causes excess melt, the piston pushes the excess melt to be discharged through the drain pipe, thus ensuring a consistent amount of melt injected each time.

[0018] 3. Through the cooperation of the inclined groove and the ejector, when the fixed mold and the movable mold are separated during the molding of metal products, the ejector will automatically push out the products stuck on the fixed mold to assist in unloading and avoid deformation and damage of the products during unloading due to sticking;

[0019] 4. After the melt is discharged, the scraper moves downward and extends into the discharge pipe to scrape off the melt remaining on the pipe wall, avoiding the impact on the product molding quality due to insufficient melt residue. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Example 1: A die-casting device for metal products, such as Figures 1-9As shown, it includes a base 1, a fixed mold 101, an injection tube 1011, a movable mold 102, a guide rod 103, a hydraulic cylinder 104, a channel tube 105, a feed tube 106, a connecting tube 301, a blocking rod 302, an exhaust pipe 303, a closing component and a positioning component.

The right side of the top of the channel tube 105 is connected and communicated with a connecting tube 301, and a blocking rod 302 is slidably connected to the connecting tube 301. The front side of the connecting tube 301 is connected and communicated with an exhaust pipe 303, and the exhaust pipe 303 is tilted upward. The blocking rod 302 is used to block the channel between the exhaust pipe 303 and the connecting tube 301. A positioning component is provided on the connecting tube 301, and a closing component is provided on the fixed mold 101.

[0039] like Figure 1 、 Figure 2 and Figure 4 As shown, the closing component includes a motor 201, a turntable 202 and a closing member 203. The motor 201 is installed on the left side of the lower part of the fixed mold 101. The turntable 202 is connected to the output shaft of the motor 201. The turntable 202 is located inside the fixed mold 101. The closing member 203 is slidably connected inside the fixed mold 101. A through hole 204 is opened on the upper side of the closing member 203. The closing member 203 is located between the channel tube 105 and the injection tube 1011 and is used to block the channel opening. The diameter of the through hole 204 is the same as that of the channel tube 105 and the injection tube 1011. A protrusion is provided on the upper end of the turntable 202, and the protrusion is slidably connected to the lower side of the closing member 203.

[0040] like Figure 2 and Figure 5-Figure 9As shown, the positioning assembly includes a reset spring 304, a moving part 305, a support block 306, a blocking block 307 and a compression spring 309. A reset spring 304 is connected between the connecting tube 301 and the blocking rod 302. A moving part 305 is welded on the top of the closing part 203. The reset spring 304 is initially in a stretched state. The moving part 305 is against the upper end of the blocking rod 302. A support block 306 is connected to the left side of the upper part of the fixed mold 101. A blocking block 307 is slidably connected to the support block 306. A plurality of compression springs 309 are evenly connected between the blocking block 307 and the support block 306. A slot 308 is provided on the upper side of the blocking rod 302. The blocking block 307 is engaged with the slot 308 to fix the blocking rod 302. An inclined portion 3071 is provided on the right side of the upper part of the blocking block 307, and the moving part 305 is in contact with the inclined portion 3071.

[0041] When performing die-casting of metal products, it is first necessary to drive the movable mold 102 to move under the action of an external electric cylinder. The electric cylinder drives the movable mold 102 to move along the guide rod 103 until the movable mold 102 is fully in contact with the fixed mold 101 and exerts sufficient closing force to resist the high pressure generated by the molten metal during the injection process, thereby avoiding metal leakage or mold deformation. Then, a certain amount of molten metal liquid is added to the discharge pipe 106, and the molten metal enters the channel pipe 105.Then start the hydraulic cylinder 104. The hydraulic cylinder 104 is equipped with a control system, which is precisely controlled by an external console. It can monitor the pressure and speed of the hydraulic cylinder 104 and adjust it according to the die-casting requirements of metal products before use. The hydraulic cylinder 104 drives the piston to move to the right, and the piston pushes the molten liquid in the channel tube 105 to move to the right. Initially, the closing member 203 is in a state of blocking the injection tube 1011. The molten liquid will accumulate between the channel tube 105 and the closing member 203, and then gradually fill the inner wall of the channel tube 105, so that the air in the channel is discharged outward through the exhaust pipe 303. The piston continues to move to the right until the molten liquid is pushed to the preset position and the gas is completely discharged. At this time, the motor 201 is started by the console, and the motor 20 The output shaft rotates to drive the turntable 202 to rotate. The protrusion on the turntable 202 will pull the closing member 203 downward, thereby driving the moving member 305 downward. Initially, the return spring 304 is in a stretched state. The moving member 305 moves downward and no longer resists the blocking rod 302. The return spring 304 rebounds and resets, driving the blocking rod 302 to move downward. The blocking rod 302 then blocks the passage between the exhaust pipe 303 and the connecting pipe 301, and at the same time blocks the connecting pipe 301. The slot 308 on the blocking rod 302 is aligned with the block 307. When the moving member 305 moves down and contacts the inclined portion 3071 on the block 307, it pushes the block 307 to move to the left. The compression spring 309 is compressed, and the block 307 moves and engages with the slot 308, thereby Fix the blocking rod 302 to prevent part of the molten metal from pushing the blocking rod 302 open under the thrust of the piston. When the closing member 203 continues to move downward until the through hole 204 is connected to the injection tube 1011, the motor 201 pauses. At this time, the hydraulic cylinder 104 continues to drive the piston to move to the right, and injects the molten metal into the cavity between the movable mold 102 and the fixed mold 101 through the injection tube 1011 through the piston. Under the action of high pressure, the molten metal quickly fills every corner of the cavity and solidifies to form the required shape in a short time. After the injection is completed, the piston stops moving automatically. After the metal product is formed, the movable mold 102 is removed by the electric cylinder, and the metal product can be taken out by the robot. Then, the piston is controlled to reset and the motor 201 is controlled to move in the reverse direction. The locking block 307 is disengaged from the card slot 308, and the blocking rod 302 is no longer fixed. When the moving part 305 moves up and contacts the upper end of the blocking rod 302, it will push the blocking rod 302 to move up and reset. The reset spring 304 is stretched, and the blocking rod 302 no longer blocks the passage between the exhaust pipe 303 and the connecting pipe 301. After the closing part 203 is reset, the motor 201 is automatically turned off.According to the above operation method, the die-casting of the metal product can be continued, and finally the work can be completed and the relevant equipment can be turned off.

[0042] Example 2: Based on Example 1, Figure 10 and Figure 11 As shown, it also includes a drain pipe 401, a connecting frame 402 and a collecting frame 403. The rear side of the connecting pipe 301 is connected to and communicated with the drain pipe 401. The drain pipe 401 is tilted downward to facilitate the rapid discharge of excess melt. The lower end of the drain pipe 401 is connected to the connecting frame 402, and the connecting frame 402 is slidably connected to the collecting frame 403 for collecting excess melt.

[0043] When the melt is exhausted, the piston pushes the melt to move and fill the right end of the channel tube 105. After the gas is exhausted, if the piston has not moved to the preset position, it means that there is an excess of solution. At this time, the piston continues to move according to the preset trajectory, which will squeeze the melt. The excess melt will be pushed into the connecting tube 301 and then discharged through the downward-inclined drain pipe 401. The drain pipe 401 is in a downward-inclined state, which can quickly discharge the excess melt and prevent the melt from entering the exhaust pipe 303. The melt discharged through the drain pipe 401 will flow into the collection frame 403 and can be taken out and processed later. When the piston moves to the preset position, the exhaust and discharge of excess solution operations are completed, and the melt can be injected normally. This design can prevent excess melt from entering the cavity between the fixed mold 101 and the movable mold 102 and causing overflow or cavity deformation. When the blocking rod 302 moves downward to block the exhaust pipe 303, it will also block the drain pipe 401 to prevent the melt to be die-cast from flowing into the drain pipe 401.

[0044] like Figure 12 and Figure 13 As shown, it also includes a push rod 501, which is symmetrically connected to the front and rear of the fixed mold 101 for slidingly ejecting the formed metal product. The front and rear sides of the closing piece 203 are provided with inclined grooves 502, and the push rod 501 is slidably connected to the inclined grooves 502.

[0045] After the molten metal enters the channel tube 105 and the exhaust operation is completed, the motor 201 starts to drive the closing member 203 to move downward, and the inclined groove 502 on the closing member 203 will push the ejector pin 501 to move to the left, so that the ejector pin 501 is retracted into the fixed mold 101. When the through hole 204 on the closing member 203 is aligned with the injection tube 1011, the molten metal is injected into the cavity between the fixed mold 101 and the movable mold 102 for molding. After molding, the movable mold 102 moves and disengages from the fixed mold 101. The motor 201 runs in reverse to move the closing member 203 upward, blocking the connection between the injection tube 1011 and the channel tube 105. At this time, the inclined groove 502 drives the ejector pin 501 to move to the right, which can push out the metal product stuck on the cavity of the fixed mold 101, making it convenient for the robot to remove the metal product. This design can avoid the problem of metal product deformation caused by sticking during the removal process.

[0046] like Figure 14-16 As shown, it also includes an electric push rod 601, a scraper 602, a dustproof plate 701 and a buffer spring 702. The electric push rod 601 is installed on the top right side of the channel tube 105 by bolts, and the scraper 602 is connected to the telescopic rod of the electric push rod 601. The size of the scraper 602 fits the size of the channel in the discharge tube 106. The two slide together and can scrape the molten liquid remaining on the inner wall of the discharge tube 106 into the channel tube 105. A dustproof plate 701 is slidably connected to the upper side of the scraper 602. A buffer spring 702 is connected between the dustproof plate 701 and the scraper 602. The size of the dustproof plate 701 fits the size of the top surface of the discharge tube 106 and is used to prevent dust from the discharge tube 106.

[0047] After the molten metal is added into the channel tube 105 through the discharge tube 106, the control console can be operated to start the electric push rod 601. Initially, the telescopic rod of the electric push rod 601 is in an extended state, and the telescopic rod is controlled to shorten, so that it drives the scraper 602 and the dustproof plate 701 to move downward. The scraper 602 contacts the inner wall of the discharge tube 106, and then pushes the molten metal remaining on the inner wall downward into the channel tube 105, which can avoid insufficient injection volume of the molten metal and affect the final molding effect of the metal product. The dustproof plate 701 contacts the top surface of the discharge tube 106, and the buffer spring 702 deforms and provides buffering. The dustproof plate 701 covers the discharge tube 106, which can play a dust-proof role. After the telescopic rod is shortened to the preset length, the electric push rod 601 automatically pauses, and the die-casting work of the metal product can be carried out. After the product is formed, when it is necessary to add melt again, the electric push rod 601 is controlled to extend and reset, driving the scraper 602 and the dust plate 701 to move upward and separate from the discharge pipe 106. The buffer spring 702 is then reset. After the telescopic rod is extended to the initial length, the electric push rod 601 is automatically closed, and the melt can be added again.

Therefore, the scope of the present disclosure should not be limited to the above-described embodiments, but should be determined not only by the appended claims but also by the equivalents of the appended claims.
