Description

Technical Field

[0001] This utility model relates to the field of metal sheet processing technology, specifically to a die-casting equipment for wrought iron products. Background Technology

[0002] In metal sheet processing, die casting is a highly efficient forming process that enables the mass production of complex metal parts, reducing material waste and improving efficiency. Iron sheets, due to their low cost and moderate strength, are widely used in wrought iron products such as home decoration, municipal facilities, and industrial parts after die casting, meeting both shape and performance requirements.

[0003] When die-casting iron sheets, air is easily trapped after the high-temperature molten metal is injected into the mold, resulting in residual air bubbles in the formed iron sheet. This weakens the mechanical properties of the iron sheet, making the finished product prone to breakage and deformation under stress, and shortening its service life. Therefore, there is an urgent need to develop a die-casting equipment for wrought iron products to solve these practical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a die-casting equipment for wrought iron products, which solves the problem that after high-temperature molten metal is injected into the mold, air is easily trapped, resulting in residual air bubbles in the formed iron sheet, which weakens the mechanical properties of the iron sheet, makes the finished product prone to breakage and deformation under stress, and shortens its service life.

[0005] To achieve the above objectives, this utility model provides a die-casting equipment for wrought iron products through the following technical solution: a housing, a die-casting assembly, and an air bubble elimination mechanism.

[0006] The die-casting assembly includes an upper mold and a lower mold for die-casting iron sheets, a material conveying pipe for connecting with an external high-temperature molten metal supply device and conveying the high-temperature molten metal into the upper mold and the lower mold for die-casting, and an electric rod for driving the upper mold to move vertically.

[0007] The bubble elimination mechanism includes an installation component and a housing. The housing is located on both sides of the bottom of the lower mold. An installation bracket is installed at equal intervals inside the housing. An ultrasonic transducer is installed at equal intervals on one side of the installation bracket. An amplitude rod is fixedly connected to the output end of the ultrasonic transducer, and one end of the amplitude rod is fixedly connected to the bottom of the lower mold. An ultrasonic generator is also fixedly installed on one side of the bottom inside the housing, and the ultrasonic generator is electrically connected to the ultrasonic transducer through a wire.

[0008] Preferably, the mounting assembly includes two sets of L-shaped mounting seats disposed on the outside of the housing, and the top of the L-shaped mounting seats is rigidly connected to the bottom of the lower mold by screws.

[0009] Preferably, the electric rod is installed on the bracket at the top of the box, and there are two sets of electric rods. The output end of the electric rod is fixedly connected to the top of the upper mold, and the top of the upper mold is connected through to the bottom of the conveying pipe. The lower mold is located at the center of the top of the box, and the lower mold is vertically corresponding to the upper mold.

[0010] Preferably, it also includes an auxiliary demolding component, which includes a first abutment rod that moves through the front of the housing, and a return spring for elastic reset of the first abutment rod is sleeved on the outside of the first abutment rod. A movable second abutment rod is installed through the lower mold, and the bottom end of the second abutment rod abuts against one end of the first abutment rod. A demolding template embedded in the lower mold is fixed to the top end of the second abutment rod, and an abutment spring for elastic reset of the second abutment rod is also provided at the center of the bottom of the lower mold.

[0011] Preferably, a limiting frame is fixedly connected to one side of the bottom of the box body, and the limiting frame is located outside one end of the first abutment rod, which is used to limit the movement of the first abutment rod.

[0012] Preferably, an abutment plate is fixed to one end of the first abutment rod on the front of the box, and the abutment plate is made of rubber.

[0013] This utility model provides a die-casting device for wrought iron products. Compared with the prior art, it has the following advantages.

[0014] 1. The operator starts the ultrasonic generator through an external controller, which transmits a high-frequency electrical signal to the ultrasonic transducer via a wire. After receiving the signal, the transducer converts it into high-frequency mechanical vibration, which is transmitted to the lower mold through the amplitude rod. The high-frequency vibration degassing of the high-temperature molten metal inside the mold removes residual air bubbles caused by air being drawn in by the liquid flow. At the same time, the amplitude rod blocks the transmission of high temperature from the mold to the transducer, preventing damage to its internal components.

[0015] 2. The operator pushes the contact plate, causing the first contact rod to move horizontally along the box. During the process, the return spring on the outside of the first contact rod is compressed. After the first contact rod moves, it touches the bottom of the second contact rod, pushing the second contact rod to move vertically upward along the lower mold. The contact spring on the outside of the second contact rod is compressed simultaneously. The top of the second contact rod causes the demolding template to move upward. The demolding template contacts the iron sheet inside the lower mold and applies force to demold, achieving convenient demolding. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] First implementation method:

[0024] refer to Figure 1-4 A die-casting equipment for wrought iron products, comprising a housing 1, a die-casting assembly, and a bubble elimination mechanism 2;

[0025] The die-casting assembly includes an upper mold 102 and a lower mold 104 for die-casting iron sheets, a material conveying pipe 103 for connecting to an external high-temperature molten metal supply device and conveying high-temperature molten metal to the upper mold 102 and the lower mold 104 for die-casting, and an electric rod 101 for driving the upper mold 102 to move vertically.

[0026] The bubble elimination mechanism 2 includes an installation component and a housing 201. The housing 201 is located on both sides of the bottom of the lower mold 104. The housing 201 is equipped with mounting brackets 202 at equal intervals. An ultrasonic transducer 203 is installed at equal intervals on one side of the mounting bracket 202. An amplitude rod 204 is fixedly connected to the output end of the ultrasonic transducer 203, and one end of the amplitude rod 204 is fixedly connected to the bottom of the lower mold 104. An ultrasonic generator 205 is also fixedly installed on one side of the bottom inside the housing 1, and the ultrasonic generator 205 is electrically connected to the ultrasonic transducer 203 through a wire.

[0027] The mounting assembly includes two sets of L-shaped mounting seats 206 disposed on the outside of the housing 201, and the top of the L-shaped mounting seats 206 is rigidly connected to the bottom of the lower mold 104 by screws 207;

[0028] The electric rod 101 is installed on the bracket on the top of the box 1, and there are two sets of electric rods 101. The output end of the electric rod 101 is fixedly connected to the top of the upper mold 102, and the top of the upper mold 102 is connected through to the bottom of the material conveying pipe 103. The lower mold 104 is located at the center of the top of the box 1, and the lower mold 104 is vertically corresponding to the upper mold 102.

[0029] When the electric rod 101 is running, it drives the upper mold 102 to move vertically until the upper mold 102 moves to the top of the lower mold 104 and completes the mold closing. Then the operator connects the material conveying pipe 103 to the external high-temperature molten metal supply equipment. The external equipment delivers the high-temperature molten metal to the internal cavity of the upper mold 102 and the lower mold 104 after the mold is closed through the material conveying pipe 103, thereby completing the die casting process of the iron sheet.

[0030] The operator starts the ultrasonic generator 205 through an external controller. The ultrasonic generator 205 transmits high-frequency electrical signals to the ultrasonic transducer 203 through wires.

[0031] After receiving the high-frequency electrical signal, the ultrasonic transducer 203 converts it into high-frequency mechanical vibration, and transmits the mechanical vibration to the interior of the lower mold 104 through the amplitude rod 204.

[0032] High-frequency mechanical vibration acts on the high-temperature molten metal inside the lower mold 104, which can degas the molten metal by vibration, thereby removing the problem of residual bubbles caused by air being drawn into the molten metal during the die casting process, and achieving the function of eliminating bubbles inside the molten metal. At the same time, the amplitude rod 204 can block the transmission of the high temperature of the lower mold 104 to the ultrasonic transducer 203, avoiding the problem of damage to the internal components of the ultrasonic transducer 203 caused by high temperature.

[0033] The L-shaped mounting base 206 cooperates with the screw 207 to fix the housing 201 to the bottom of the lower mold 104. The advantage of using a rigid connection is to ensure the positional stability between the housing 201 and the lower mold 104, avoid the vibration generated by the ultrasonic transducer 203 during operation causing the housing 201 to shift, and ensure the reliability of the contact between the amplitude rod 204 and the lower mold 104.

[0034] At the same time, the vibration transmission efficiency is improved. The rigid connection can reduce the energy loss of vibration during the transmission process and ensure that the mechanical vibration generated by the ultrasonic transducer 203 can be efficiently transmitted to the interior of the lower mold 104.

[0035] Second implementation method:

[0036] During the die casting process of iron sheets, it was also found that the iron sheets are prone to sticking to the mold cavity, which leads to difficulties in demolding, or deformation and surface damage of the iron sheets caused by forced demolding, resulting in poor yield. To address this issue, the device is also designed with an auxiliary demolding component, specifically as follows:

[0037] refer to Figure 3 , 5 In the second embodiment of this utility model, an auxiliary demolding component 3 is also included. The auxiliary demolding component 3 includes a first abutment rod 301 that is movable through the front of the box body 1, and a reset spring 302 for elastic reset of the first abutment rod 301 is sleeved on the outside of the first abutment rod 301. A movable second abutment rod 303 is installed through the lower mold 104, and the bottom end of the second abutment rod 303 abuts against one end of the first abutment rod 301. A demolding template 304 embedded in the lower mold 104 is fixed to the top end of the second abutment rod 303. An abutment spring 305 for elastic reset of the second abutment rod 303 is also provided at the center of the bottom of the lower mold 104.

[0038] A limiting frame 306 is fixedly connected to one side of the bottom inside the box 1, and the limiting frame 306 is located on the outside of one end of the first abutment rod 301, which is used to limit the movement of the first abutment rod 301. An abutment plate 307 is fixedly connected to one end of the first abutment rod 301 on the front of the box 1, and the abutment plate 307 is made of rubber.

[0039] After die casting is completed, the electric rod 101 drives the upper mold 102 to move upward to open the mold;

[0040] The operator pushes the contact plate 307, which causes the first contact rod 301 to move horizontally along the box 1. During the movement, the return spring 302 on the outside of the first contact rod 301 is compressed.

[0041] As the first abutment rod 301 moves, one end of it contacts the bottom end of the second abutment rod 303 and generates a resisting force, pushing the second abutment rod 303 to move vertically upward along the lower mold 104;

[0042] When the second abutment rod 303 moves upward, the abutment spring 305 on its outer side is compressed. At the same time, the top of the second abutment rod 303 drives the demolding template 304 to move upward synchronously. The demolding template 304 contacts the iron sheet formed by die casting in the lower mold 104 and applies an upward pushing force to realize the demolding of the iron sheet. This process can avoid the problem of demolding difficulty caused by the iron sheet sticking to the cavity of the lower mold 104, or the problem of iron sheet deformation and surface damage caused by forced demolding. It realizes the convenient demolding function and solves the problems of low efficiency and poor yield of iron sheet removal after traditional die casting.

[0043] After the iron sheet is demolded, the operator releases the contact plate 307. The return spring 302 pushes the first contact rod 301 to move in the opposite direction in the horizontal direction through its own elastic restoring force until the first contact rod 301 returns to its initial position.

[0044] At the same time, the resisting spring 305 pushes the second resisting rod 303 to move in the opposite direction in the vertical direction through its own elastic restoring force, which drives the demolding template 304 to reset synchronously, preparing for the next die casting process;

[0045] The limiting bracket 306 restricts the movement of the first abutment rod 301 to avoid the problem that the upward stroke of the second abutment rod 303 is shortened due to the movement and deviation of the first abutment rod 301, resulting in insufficient upward movement distance of the template 304;

[0046] The contact plate 307 is made of rubber, which on the one hand increases the contact area between the operator's hand and the first contact rod 301, making it easier for the operator to apply force to push the first contact rod 301. On the other hand, the rubber material has a certain elasticity, which can buffer the reaction force when the operator applies force, avoiding hand discomfort or injury caused by direct contact with the metal first contact rod 301, thus improving operation safety and comfort.
