Description

Technical Field

[0001] This application relates to the field of die casting mold technology, and more particularly to an anode low-pressure mold. Background Technology

[0002] After low-pressure die casting, the metal surface of the workpiece is easily oxidized when exposed to air. If it needs to be stored for a long time, the workpiece surface needs to be treated with anti-oxidation, such as by applying oil. However, applying oil not only increases the workload, but also makes the surface of the workpiece more likely to absorb dust and impurities. It also needs to be cleaned during use, which also increases the workload. Summary of the Invention

[0003] The purpose of this application is to provide an anodizing low-pressure mold that produces workpieces that can resist oxidation for a long time without the need for oiling.

[0004] To achieve the above objectives, this application provides an anode low-pressure mold: including a mold base, the mold base having a worktable, a fixed template fixedly connected to the worktable, a lower mold cavity formed on the upper surface of the fixed template, a movable mold rotatably connected to the worktable, a mold top core fixedly connected to the surface of the movable mold facing the fixed template, suitable for embedding into the lower mold cavity to form a complete mold cavity, a driver connected to the movable mold, suitable for driving the movable mold to rotate relative to the worktable, a self-resetting switch provided on the upper surface of the worktable, suitable for being controlled by the pressure of the movable mold, and a power supply box provided below the worktable, suitable for being electrically connected to the fixed template through the self-resetting switch, so that the workpiece material is powered only when the mold is closed, and the entire mold is de-energized when the mold is open, so as long as the mold cavity is in the open state, it is relatively safe.

[0005] As a preferred embodiment, the upper surface of the worktable has a pair of shaft supports with shaft holes, and the side of the moving mold has an end shaft, which is suitable for cooperating with the shaft holes to form a rotating pair and restrict the degree of freedom of movement of the moving mold.

[0006] As a preferred embodiment, the end face of the mold core of the moving mold is parallel to the axis of the end shaft, and the upper surface of the fixed mold plate is parallel to the axis of the shaft hole, so that the moving mold can cooperate with the fixed mold plate in a horizontal state.

[0007] As a preferred embodiment, the side of the moving mold also has a pressure block, which is suitable for contacting the self-reset switch to connect the internal circuit of the self-reset switch.

[0008] As a preferred embodiment, there are two moving molds and two pairs of shaft supports. The two moving molds are rotatably connected to the two pairs of shaft supports respectively. Compared with a single moving mold, the range of motion of the two equally distributed moving molds is smaller.

[0009] As a preferred embodiment, a support is fixedly connected to the bottom of the worktable, and the driver is connected between the support and the moving mold to drive the moving mold to move relative to the fixed template.

[0010] As a preferred embodiment, the actuator is a hydraulic cylinder, including a cylinder barrel and a telescopic rod. The lower end of the cylinder barrel is rotatably connected to the bracket, and the upper end of the telescopic rod is rotatably connected to the moving mold, ensuring that the actuator has sufficient angular flexibility when working.

[0011] As a preferred embodiment, a first hinge frame is fixedly connected to the outer side of the bracket, the cylinder is rotatably connected to the first hinge frame via a first hinge shaft, a second hinge frame is fixedly connected to the outer surface of the moving mold, and the telescopic rod is rotatably connected to the second hinge frame via a second hinge shaft, so that the driver can adaptively deflect angles when performing telescopic movements.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By connecting the mold to the anode, the workpiece is in an electron-deficient state after molding, making it difficult to continue to be oxidized. As long as insulation is done well, it can be in contact with air for a long time, which has excellent anti-oxidation properties and effectively saves anti-oxidation costs.

[0014] (2) By designing a self-resetting switch, the workpiece material is powered on when the mold is closed and powered off when the mold is opened, which not only ensures the de-electrolysis effect of the molded part, but also avoids the risk of electric shock when the mold is open.

[0021] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0025] like Figure 1-5The low-pressure anode mold shown includes a mold base 1 placed on a horizontal surface. The mold base 1 has a horizontal worktable 101. A fixed template 107 is fixedly connected to the worktable 101. The upper surface of the fixed template 107 has a lower mold cavity 108 for forming the bottom shape of the low-pressure casting workpiece. There are several lower mold cavities 108, which are equidistantly arranged along the left and right center lines of the fixed template 107. The worktable 101 is also rotatably connected to a moving mold 2. The upper surface of the worktable 101 has a pair of shaft brackets 105. The shaft brackets 105 have shaft holes 106. The opposite sides of the moving mold 2 have coaxial end shafts 202. The two end shafts 202 are close to the same side of the moving mold 2. The end shafts 202 and the shaft holes 106 cooperate to form a rotating pair, which is suitable for restricting the degree of freedom of movement of the moving mold 2.

[0026] The moving mold 2 has a mold core 203 fixedly connected to the surface of the fixed mold plate 107, which is used to embed into the lower mold cavity 108 to form a complete mold cavity. There are two moving molds 2, and the two moving molds 2 have the same structure and are symmetrical. Therefore, there are also two pairs of shaft brackets 105. The two moving molds 2 are rotatably connected to the two pairs of shaft brackets 105 respectively. The number and position of the mold cores 203 on the two moving molds 2 correspond to the lower mold cavity 108. The mold cores 203 at the same position abut against each other to form a complete embedded structure, which is inserted into the lower mold cavity 108 to extrude the molten material in the lower mold cavity 108 into a specific shape. The end face of the mold core 203 of the moving mold 2 is parallel to the axis of the end shaft 202, and the upper surface of the fixed mold plate 107 is parallel to the axis of the shaft hole 106. When the moving mold 2 is rotated to the horizontal position, it is exactly above the fixed mold plate 107. At this time, the moving mold 2 and the fixed mold plate 107 are closed.

[0027] The moving mold 2 is connected to a driver 5, which drives the moving mold 2 to rotate relative to the worktable 101. A support 102 is fixedly connected to the lower part of the worktable 101. Both the worktable 101 and the support 102 are made of insulating material. The driver 5 is connected between the support 102 and the moving mold 2. The driver 5 is a hydraulic cylinder, including a cylinder barrel 501 and a telescopic rod 502 that cooperate with each other. It can generate a large amount of power to drive the heavier moving mold 2. The lower end of the cylinder barrel 501 is rotatably connected to the support 102. A first hinge frame 103 is fixedly connected to the outer side of the support 102. The cylinder barrel 501 is rotatably connected to the first hinge frame 103 through a first hinge shaft 3. The upper end of the telescopic rod 502 is rotatably connected to the moving mold 2. A second hinge frame 201 is fixedly connected to the outer surface of the moving mold 2. The telescopic rod 502 is rotatably connected to the second hinge frame 201 through a second hinge shaft 4. In this way, when the driver 5 performs telescopic movement, its own angle can be adaptively changed, so that the force on the driver 5 is always along its own axis.

[0028] A self-reset switch 104 is provided on the upper surface of the workbench 101, which can be controlled by the pressure of the moving mold 2. The side of the moving mold 2 also has a pressure block 204, which is suitable for contacting the self-reset switch 104. When the self-reset switch 104 is pressed, the internal circuit is connected. When the self-reset switch 104 is released, the button supported by the spring is reset and its internal circuit is disconnected. A power supply box 6 is also provided below the workbench 101, which needs to be electrically connected to the fixed template 107 through the self-reset switch 104. That is to say, when the moving mold 2 and the fixed template 107 are separated, the fixed template 107 is de-energized. Afterwards, when the moving mold 2 and the fixed template 107 are closed, the fixed template 107 is energized.

[0029] Working principle: In the initial state, the actuator 5 retracts, and the two moving molds 2 rise upwards away from the fixed mold platen 107, pouring the molten raw material into all the lower mold cavities 108. Then, the actuator 5 extends, and the two moving molds 2 rotate downwards towards the fixed mold platen 107 until the moving molds 2 and the fixed mold platen 107 close. The mold top cores 203, which abut against each other, squeeze the molten raw material in the lower mold cavities 108 into a specific shape. At the same time, the pressure block 204 of the moving mold 2 will also contact the self-reset switch 104. The self-reset switch 104 allows the power supply box 6 to supply power to the fixed mold platen 107. At this time, the fixed mold platen 107 and the moving mold contact 2 both act as anodes. The process causes the metal material inside the mold cavity to lose electrons. After the mold is opened and the workpiece is cooled and formed, it will actively attract electrons from the air. Since there are very few electrons in the air, the reduction process of the workpiece is very slow. The workpiece is not easily oxidized due to the lack of electrons when exposed to the air, and thus can maintain the stability of the workpiece material for a long time. It should be noted that the formed workpiece cannot be placed directly on the ground, but needs to be placed on an insulating platform. Insulating gloves should also be worn when handling the workpiece. The workpiece lacking electrons only comes into contact with the air in addition to contact with the insulating platform or gloves. There is no need to apply oil to the surface of the workpiece, and it can resist oxidation for a long time.

Those skilled in the art should understand that this application is not limited to the above embodiments.
