This facilitates removal from the lower mold, reducing the probability of deformation and scratches, and improving product quality and processing efficiency.

Description

Technical Field

[0001] This utility model relates to the field of casting technology, and in particular to a mold for casting characters on the end face of a brake disc. Background Technology

[0002] Brake disc end face casting mold is a tool or device specifically used to cast text, numbers, logos and other information onto the end face of the brake disc during the casting process. Through the combination of mold design and casting process, it achieves the formation of clear and accurate lettering on the end face of the casting.

[0003] When using a lower and upper die for casting brake discs, the brake disc is tightly fitted to the cavity of the lower die during the casting process, making it difficult for the formed brake disc to detach smoothly from the lower die. Operators usually need to manually pry or tap the edge of the brake disc with tools such as pry bars and hammers. This is not only time-consuming and laborious, but also prone to causing scratches on the end face of the brake disc, wear on the cast characters, and even deformation of the brake disc body due to uneven force, which seriously affects product quality and reduces processing efficiency. Utility Model Content

[0004] The technical problem this utility model aims to solve is that when using a lower and upper die for casting brake discs, the brake disc is tightly fitted to the cavity of the lower die during the casting process, making it difficult for the formed brake disc to detach smoothly from the lower die. Operators usually need to manually pry or tap the edge of the brake disc with tools such as pry bars and hammers, which is not only time-consuming and laborious, but also prone to scratches on the end face of the brake disc and wear on the cast characters due to uneven force, and may even cause deformation of the brake disc body, seriously affecting product quality and reducing processing efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a brake disc end face casting mold, including a lower casting mold and an upper casting mold. The upper casting mold is inserted into the inner wall of the lower casting mold. The inner wall of the lower casting mold is provided with an ejection device. After the brake disc is cast, the ejection device can activate an electric telescopic rod to drive the abutment frame to move to one end, push the slider and the ejection ring block to move upward, so that the formed brake disc can be ejected from the inner wall of the lower casting mold for easy removal.

[0006] Preferably, the ejection device includes an ejection ring block and two sliders, wherein one side of the sliders is fixedly installed in the inner wall of the ejection ring block, the inner wall of the lower die for casting is provided with a circular groove, and the inner wall of the circular groove is symmetrically provided with sliding holes, wherein the ejection ring block and the sliders are respectively slidably installed in the inner walls of the circular groove and the sliding holes; two springs, wherein the two ends of the springs are respectively fixedly installed on one side of the sliders and one side of the lower die for casting; an electric telescopic rod, wherein one end of the electric telescopic rod is fixedly installed on the outer surface of the lower die for casting; an abutment frame, wherein one side of the abutment frame is fixedly installed on the output end side of the electric telescopic rod, and both ends abut against one side of the two sliders respectively; and a limiting mechanism, wherein the limiting mechanism is disposed between one side of the sliders and one side of the lower die for casting, for limiting and fixing the sliders and the ejection ring block during the forming process.

[0007] The effect achieved by the above-mentioned components is as follows: By setting the ejection device, during the process of installing the lower and upper molds of the lettering on the brake disc stamping machine or casting machine, after the brake disc is formed, the limiting mechanism is first opened, and then the electric telescopic rod is activated to retract, driving the abutment frame to move to one end. The other end will abut against and push the slider to move upward in the sliding hole, causing the spring to retract, thereby driving the ejection ring block to move upward in the circular groove, ejecting the brake disc after the lettering is formed, making it easier to remove it from the inside of the lower mold, reducing the probability of deformation and scratches, and improving product quality and processing efficiency. Conversely, when it is removed and used for further casting, the electric telescopic rod will drive the abutment frame to reset, and the spring will drive the slider and ejection ring block to reset and lock into the circular groove, making it easier to continue casting and using it later.

[0008] Preferably, both ends of the abutment frame are provided with sliding grooves, and several L-shaped blocks are symmetrically fixedly installed on one side of the lower die of the casting, wherein one end of the L-shaped block is slidably installed in the inner wall of the sliding groove.

[0009] The effect achieved by the above components is that by setting the sliding groove and L-shaped block, the two ends of the abutment frame can be limited and supported, so that it is not easy to shake when moving back and forth, thus improving the stability of the abutment.

[0010] Preferably, the limiting mechanism includes a rectangular hole block, wherein one side of the rectangular hole block is fixedly installed on one side of the lower die of the casting, and a slot is provided on one side of the slider; a limiting rod, wherein one end of the limiting rod is slidably installed in the inner wall of the rectangular hole block, and the other end is inserted into the inner wall of the slot.

[0011] The effect achieved by the above-mentioned components is as follows: by setting a limiting mechanism, when the brake disc is being cast, the limiting rod can be manually slid to a certain position on one end of the rectangular hole block, so that one end of it is inserted into the slot on the slider, which can fix the ejector ring block and prevent it from sliding upward. In this way, the problem of accidentally touching the slider during the casting process and affecting the casting effect is less likely to occur, thus improving the casting quality.

[0012] Preferably, the longitudinal section of the limiting rod is L-shaped.

[0013] The effect achieved by the above components is that by setting the shape of the limiting rod to L, it is convenient to hook one end and pull it when it needs to be pulled.

[0014] Preferably, a reinforcing rod is symmetrically fixedly installed on the outer surface of the output end of the electric telescopic rod, and one side of the reinforcing rod is fixedly installed on one side of the abutment frame.

[0015] The effect achieved by the above components is that by setting up reinforcing rods, the connection area between the output end of the electric telescopic rod and the abutment frame can be increased, making the connection more secure and stable, and less prone to breakage or damage.

[0016] Preferably, several round rollers are rotatably mounted on one side of both ends of the abutment frame, and the side of the abutment frame with round rollers is located on the end near the slider.

[0017] The effect achieved by the above components is that by setting the round roller, the wear between one end of the abutment frame and the slider can be reduced, making it easier to push and push them, and improving the service life of both.

[0018] Preferably, the ejection device further includes two support telescopic rods, wherein the outer surface of the support telescopic rods penetrates the inner wall of the spring and the two ends are respectively fixedly installed on one side of the slider and one side of the lower die of the casting.

[0019] The effect achieved by the above components is that by setting up a support telescopic rod, the inner wall of the spring can be supported and reinforced, making it less prone to deformation, bending and damage during use, thus improving its service life.

[0020] The beneficial effects of this utility model are:

[0021] By setting an ejector device, during the process of installing the lower and upper molds for casting on a brake disc stamping or casting machine, after the brake disc is formed, the limiting mechanism is first opened, and then the electric telescopic rod is activated to retract, driving the abutment frame to move to one end. The other end will abut against and push the slider to move upward in the sliding hole, thereby driving the ejector ring block to move upward in the circular groove, ejecting the brake disc after the casting is completed. This makes it easier to remove it from the inside of the lower mold, reducing the probability of deformation and scratches, and improving product quality and processing efficiency. Conversely, when it is removed and used for further casting, the electric telescopic rod will drive the abutment frame to reset, and the spring will drive the slider and ejector ring block to reset and lock into the circular groove, facilitating the subsequent casting and use.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Figure 1-4 The mold shown is a brake disc end face casting mold, including a lower casting mold 1 and an upper casting mold 3. The upper casting mold 3 is inserted into the inner wall of the lower casting mold 1. The inner wall of the lower casting mold 1 is provided with an ejector device 2. After the brake disc is cast, the ejector device 2 can activate the electric telescopic rod 26 to drive the abutment frame 27 to move to one end, push the slider 24 and the ejector ring block 23 to move upward, so that the formed brake disc can be ejected from the inner wall of the lower casting mold 1 for easy removal.

[0031] Figure 1-4 The ejection device 2 shown includes an ejection ring block 23 and two sliders 24. One side of the sliders 24 is fixedly installed in the inner wall of the ejection ring block 23. The inner wall of the lower die 1 has a circular groove 21, and the inner wall of the circular groove 21 has symmetrical sliding holes 22. The ejection ring block 23 and the sliders 24 are respectively slidably installed in the inner walls of the circular groove 21 and the sliding holes 22. Two springs 25 are fixedly installed on one side of the sliders 24 and one side of the lower die 1. An electric telescopic rod 26 is fixedly installed on one end of the electric telescopic rod 26 on the outer surface of the lower die 1. An abutment frame 27 is fixedly installed on one side of the output end of the electric telescopic rod 26, and both ends abut against one side of the two sliders 24. A limiting mechanism 28 is set between one side of the sliders 24 and one side of the lower die 1 to limit and fix the sliders 24 and the ejection ring block 23 during the forming process. By setting the ejector device 2, when the lower die 1 and upper die 3 are installed on the brake disc stamping machine or casting machine for use, after the brake disc is formed, the limiting mechanism 28 is opened first, and then the electric telescopic rod 26 is activated to retract, driving the abutment frame 27 to move to one end. The other end will abut against and push the slider 24 to move upward in the sliding hole 22, driving the spring 25 to retract, thereby driving the ejector ring block 23 to move upward in the circular groove 21, ejecting the brake disc after the casting is formed, making it easier to remove it from the inside of the lower die 1, reducing the probability of deformation and scratches, and improving product quality and processing efficiency. Conversely, when it is taken out and used for casting again, the electric telescopic rod 26 will drive the abutment frame 27 to reset, and the spring 25 will drive the slider 24 and the ejector ring block 23 to reset and lock into the circular groove 21, making it easier to continue casting for use later.

[0032] Figure 1-4 The abutment frame 27 shown has grooves 29 on both sides at both ends. Several L-shaped blocks 210 are symmetrically fixed on one side of the lower die 1, with one end of each L-shaped block 210 slidingly installed in the inner wall of the groove 29. By setting the grooves 29 and L-shaped blocks 210, the two ends of the abutment frame 27 can be limited and supported, making it less prone to shaking during back-and-forth movement and improving the stability of the abutment.

[0033] Figure 1-4 The limiting mechanism 28 shown includes a rectangular hole block 281, one side of which is fixedly installed on one side of the lower die 1 for casting characters, and a slot 283 is provided on one side of the slider 24; a limiting rod 282, one end of which is slidably installed in the inner wall of the rectangular hole block 281, and the other end is inserted into the inner wall of the slot 283. By setting the limiting mechanism 28, when the brake disc is being cast, the limiting rod 282 can be manually slid to a certain position on the rectangular hole block 281, so that one end is inserted into the slot 283 on the slider 24, thus fixing the ejector ring block 23 and preventing upward sliding. This reduces the possibility of accidentally touching the slider 24 during the casting process and affecting the casting effect, improving the casting quality. The longitudinal section of the limiting rod 282 is L-shaped. By setting the shape of the limiting rod 282 to L-shape, it is easy to hook and pull one end when it needs to be pulled.

[0034] Figure 1-4 The output end of the electric telescopic rod 26 shown is symmetrically fixed with reinforcing rods 211, one side of which is fixedly mounted on one side of the abutment frame 27. By setting the reinforcing rods 211, the connection area between the output end of the electric telescopic rod 26 and the abutment frame 27 can be increased, making the connection more secure and stable, and less prone to breakage or damage. Several round rollers 212 are rotatably mounted on one side of both ends of the abutment frame 27, with the side of the abutment frame 27 with the round rollers 212 located at the end near the slider 24. By setting the round rollers 212, the abutment wear between one end of the abutment frame 27 and the slider 24 can be reduced, facilitating abutment and pushing, and improving the service life of both. The ejection device 2 also includes two supporting telescopic rods 213, the outer surface of which penetrates the inner wall of the spring 25, and the two ends are respectively fixedly mounted on one side of the slider 24 and one side of the lower die 1. By setting up the support telescopic rod 213, the inner wall of the spring 25 can be supported and reinforced, making it less prone to deformation, bending and damage during use, thus improving its service life.

[0035] Working principle: When the lower die 1 and upper die 3 are installed on a brake disc stamping machine or casting machine, after the brake disc is formed, the limiting rod 282 is first pulled to one end within the inner wall of the rectangular hole 281, causing one end to be pulled out of the slot 283. Then, the electric telescopic rod 26 is activated to retract, driving the abutment frame 27 to move to one end. This abuts and pushes the slider 24 upward in the sliding hole 22, causing the spring 25 to contract, thereby driving the ejector ring 2. 3. Moving upward in the circular groove 21, it pushes out the brake disc after the character is cast, making it easier to remove from the inside of the lower mold 1, reducing the probability of deformation and scratches, and improving product quality and processing efficiency. Conversely, when it is removed and used for further casting, the electric telescopic rod 26 will drive the abutment frame 27 to reset, while the spring 25 will drive the slider 24 and the ejector ring 23 to reset and lock into the circular groove 21. Then, one end of the limit rod 282 can be inserted into the slot 283 to limit it, which is convenient for the character to be cast and used in the later stage.

[0036] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
