Description

Technical Field

[0001] This utility model relates to the field of die-casting mold technology, specifically to a die-casting mold for producing motor mounting plates. Background Technology

[0002] The mounting plate for a certain servo motor is made of aluminum alloy. One side is concave, with uneven mounting points on the concave side, while the other side is convex, with decorative grooves on both sides of the convex surface. Due to its complex structure, it can generally only be machined from a single piece of blank. This process is not only difficult and time-consuming, but also results in significant material loss. The weight of the machined part is only 15% of the original thick plate material, with a material loss as high as 85%, leading to excessively high overall production costs. Furthermore, the demand for this type of motor mounting plate is large; if milling is continued indefinitely, the production cycle will be too long, potentially leading to supply shortages. Utility Model Content

[0003] To solve at least one of the above technical problems, this utility model provides a die-casting mold for producing motor mounting plates.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] This utility model provides a die-casting mold for producing motor mounting plates, comprising:

[0006] The lower mold base plate has a lower mold insert fixed in the middle of its upper side. Slider blocks are provided on opposite sides of the lower mold insert. The sliders are slidably connected to the lower mold base plate and can slide in the direction of approaching / moving away from the lower mold insert. A gate is provided on the other side of the lower mold insert.

[0007] An upper mold base plate is located directly above the lower mold base plate, and an upper mold insert is fixed to the middle of its lower side; the lower mold base plate, the lower mold insert, the slider, and the upper mold insert are used to close the mold and form a cavity, and the gate communicates with the cavity; a gate sleeve is also fixed to the upper mold base plate, and the gate sleeve is used to connect with the gate when the mold is closed;

[0008] An ejection mechanism is located directly below the lower mold base plate. An ejector rod is fixed on the ejection mechanism, and the upper end of the ejector rod passes through the lower mold base plate and extends to the lower side of the cavity.

[0009] The beneficial effects of this utility model are:

[0010] This invention utilizes a lower mold base plate, a lower mold insert, a slider, and an upper mold insert to form a mold cavity. The lower mold insert can be used to form complex structures such as steps on the concave bottom and inner wall of the mounting plate workpiece. The upper mold insert can be used to form complex structures such as steps on the outer bottom of the mounting plate workpiece. The slider can be used to form complex structures such as decorative grooves on the outer wall of the mounting plate workpiece. This allows for the one-time die casting of similar parts of the mounting plate workpiece, improving production efficiency. At the same time, the casting has high dimensional accuracy, significantly reducing the workload and material loss of machining, and lowering production costs.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, a slanted guide rod is provided directly above the slider. The upper end of the slanted guide rod is fixed to the lower side of the upper mold base plate, and the lower end of the slanted guide rod extends away from the lower mold insert and is slidably connected to the slider.

[0013] When the mold is closed, the inclined guide rod can guide and drive the slider to move towards the lower mold insert; when the mold is opened, the inclined guide rod can guide and drive the slider away from the lower mold insert; thus, there is no need for an external driving device to drive the slider to move, which improves the efficiency of mold closing and opening.

[0014] Furthermore, it also includes a slide block, wherein the slider is fixed to the side of the slide block near the lower mold insert, and the slide block is slidably connected to the lower mold base plate; a pressure strip is also fixed on the lower mold base plate, the pressure strip is located on both sides of the slide block and arranged along the sliding direction of the slide block, and the lower side of the pressure strip contacts the upper side of the slide block; the inclined guide rod slides through the slide block.

[0015] By pressing the pressure strip onto the slide block, the pressure strip is prevented from moving upward with the inclined guide rod when the mold is opened, thus improving the movement stability of the slider. At the same time, the slider is fixed to the side of the slide block near the lower mold insert, which allows for greater flexibility in its shape design and makes it easier to match the complex structure of the outer wall of the mounting plate workpiece.

[0016] Furthermore, the upper side of the lower mold base plate is provided with multiple guide holes, which are distributed around the lower mold insert. The lower side of the upper mold base plate is also fixed with multiple guide pillars, which correspond one-to-one with the multiple guide holes and slide in fit.

[0017] This facilitates the movement of the lower mold base plate and the upper mold base plate towards each other, moving away from or closer to each other, thus improving the accuracy of mold closing and opening.

[0018] Furthermore, a sprue seat is fixed inside the sprue. When the mold is closed, the sprue sleeve is fitted onto the sprue seat. The sprue seat has a notch on the side near the lower mold insert, and the sprue sleeve communicates with the cavity through the notch.

[0019] It improves the sealing performance when the gate and gate sleeve are joined.

[0020] Furthermore, a cooling ring is fitted in the middle of the sprue sleeve, and an annular cooling groove is provided between the inner wall of the cooling ring and the outer wall of the sprue sleeve. A cooling water connector is fixed on the cooling ring, and the cooling water connector is connected to the annular cooling groove.

[0021] During die casting, after molten metal is injected through the sprue bushing, external cooling water is connected through a cooling water connector. The cooling water is then directed into an annular cooling tank to cool the metal inside the sprue bushing, which facilitates pressure maintenance inside the mold cavity.

[0022] Furthermore, a lower slag bag extension block is fixed on the lower mold base plate, and the lower slag bag extension block and the gate are located on opposite sides of the lower mold insert; an upper slag bag extension block is fixed on the upper mold base plate, and the upper slag bag extension block is located directly above the lower slag bag extension block; when the mold is closed, the lower slag bag extension block and the upper slag bag extension block enclose each other to form a slag-containing cavity, and the slag-containing cavity is connected to the mold cavity.

[0023] During die casting, the pressure of the molten metal pushes the air in the mold cavity into the slag cavity, and the air is discharged through the gap between the lower slag extension block and the upper slag extension block. The slag formed by the molten metal that first enters the mold cavity is also pushed into the slag cavity by the subsequent molten metal, which facilitates the elimination of defects caused by segregation and uneven crystallization, and improves the die casting quality of the mounting plate workpiece.

[0024] Furthermore, the ejection mechanism includes a support foot and an ejector pin fixing assembly. The upper end of the support foot is fixedly connected to the lower mold base plate, and the support foot slides through the ejector pin fixing assembly. The lower end of the ejector rod is fixedly connected to the ejector pin fixing assembly.

[0025] By guiding the ejector pin fixing assembly with the support feet, it is ensured that the ejector pin fixing assembly evenly drives multiple ejector rods to move up and down relative to the lower mold base plate, which facilitates the ejector rods to evenly eject the mounting plate workpiece when the mold is opened.

[0026] Furthermore, the ejector pin fixing assembly includes an ejector pin fixing plate, through which the ejector rod passes; an ejector pin baffle is provided on the lower side of the ejector rod fixing plate, and the ejector pin baffle is connected to the ejector pin fixing plate by screws.

[0027] The lower end of the ejector rod is supported by the ejector pin baffle, which ensures good stability of the ejector rod. The ejector rod and ejector pin baffle can be removed or replaced by unscrewing the screws, making disassembly and assembly convenient.

[0028] Furthermore, the support foot is also provided with a long bolt, which passes through the support foot and is threadedly connected to the lower mold base plate.

[0029] Easy to assemble and disassemble the support legs. Attached Figure Description

[0039] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0040] This utility model refers to Figure 1-5 .

[0041] This utility model provides a die-casting mold for producing motor mounting plates, comprising:

[0042] The lower mold base plate 1 has a lower mold insert 2 fixed in the middle of its upper side. The lower mold insert 2 has sliders 3 on opposite sides. The sliders 3 are slidably connected to the lower mold base plate 1 and can slide in the direction of approaching / moving away from the lower mold insert 2. The other side of the lower mold insert 2 has a gate.

[0043] The upper mold base plate 4 is located directly above the lower mold base plate 1, and an upper mold insert 5 is fixed to the middle of its lower side; the lower mold base plate 1, lower mold insert 2, slider 3 and upper mold insert 5 are used to close the mold and form a cavity, and the gate is connected to the cavity; a gate sleeve 6 is also fixed on the upper mold base plate 4, and the gate sleeve 6 is used to connect with the gate when the mold is closed;

[0044] The ejection mechanism is located directly below the lower mold base plate 1. An ejector rod 13 is fixed on the ejection mechanism. The upper end of the ejector rod 13 passes through the lower mold base plate 1 and extends to the lower side of the cavity.

[0045] Working principle:

[0046] During installation, the lower mold base plate 1 is fixed to the lower mold base of the die-casting machine, and the upper mold base plate 4 is fixed to the upper mold base of the die-casting machine. The lower and upper mold bases of the die-casting machine move closer together to close the mold; they also move further apart to open the mold. When the mold is closed, the lower mold base plate 1, lower mold insert 2, slider 3, and upper mold insert 5 form the mold cavity. Simultaneously, the sprue sleeve 6 aligns with the sprue to prevent molten metal from leaking out from the top of the sprue during die casting. During die casting, the die-casting punch forces molten metal into the mold cavity through the sprue sleeve 6. The portion of the mold cavity surrounding the lower mold insert 2 forms the sidewall of the motor mounting plate, and the portion of the mold cavity between the lower mold insert 2 and the upper mold insert 5 forms the bottom wall of the motor mounting plate. When the mold is opened, an external drive device can move the slider 3 away from the mold cavity, and the ejector mechanism moves the ejector rod 13 upwards, thus ejecting the formed motor mounting plate from the mold cavity. The die-cast mounting plate workpiece 100 is sent to the machining workshop for a small amount of milling and finishing to obtain the finished product.

[0047] This invention utilizes a lower mold base plate 1, a lower mold insert 2, a slider 3, and an upper mold insert 5 to close the mold and form a cavity. The lower mold insert 2 can be used to form complex structures such as steps on the concave bottom and inner wall of the mounting plate workpiece 100. The upper mold insert 5 can be used to form complex structures such as steps on the outer bottom of the mounting plate workpiece 100. The slider 3 can be used to form complex structures such as decorative grooves on the outer wall of the mounting plate workpiece 100. This allows for the one-time die casting of similar parts of the mounting plate workpiece 100, improving production efficiency. At the same time, the casting has high dimensional accuracy, significantly reducing the workload and material consumption of machining, and lowering production costs.

[0048] Furthermore, a slanted guide rod 7 is provided directly above the slider 3. The upper end of the slanted guide rod 7 is fixed to the lower side of the upper mold base plate 4, and the lower end of the slanted guide rod 7 extends away from the lower mold insert 2 and is slidably connected to the slider 3.

[0049] When the mold is closed, the inclined guide rod 7 can guide and drive the slider 3 to move towards the lower mold insert 2; when the mold is opened, the inclined guide rod 7 can guide and drive the slider 3 to move away from the lower mold insert 2; thus, there is no need for an external driving device to drive the slider 3 to move, which improves the efficiency of mold closing and opening.

[0050] Furthermore, it also includes a slide block 8, the slider 3 is fixed to the side of the slide block 8 near the lower mold insert 2, the slide block 8 is slidably connected to the lower mold base plate 1; a pressure strip 9 is also fixed on the lower mold base plate 1, the pressure strip 9 is located on both sides of the slide block 8 and arranged along the sliding direction of the slide block 8, the lower side of the pressure strip 9 contacts the upper side of the slide block 8; the inclined guide rod 7 slides through the slide block 8.

[0051] By pressing the pressure strip 9 onto the slide block 8, the pressure strip 9 is prevented from moving upward with the inclined guide rod 7 when the mold is opened, thus improving the movement stability of the slider 3. At the same time, the slider 3 is fixed to the side of the slide block 8 near the lower mold insert 2, and its shape design is more flexible, making it easier to match the complex structure of the outer wall of the mounting plate workpiece 100.

[0052] Preferably, the pressure strip 9 is connected to the lower mold base plate 1 by screws; this facilitates maintenance. Furthermore, multiple rectangular guide rails 10 are fixed to the lower side of the slide block 8, and the rectangular guide rails 10 are embedded in the lower mold base plate 1 and slidably connected to it; this improves the stability of the slide block 8's movement. In addition, at least two inclined guide rods 7 are correspondingly arranged above each slider 3.

[0053] Furthermore, the upper side of the lower mold base plate 1 is provided with a plurality of guide holes 11, which are distributed around the lower mold insert 2. The lower side of the upper mold base plate 4 is also fixed with a plurality of guide posts 12, which correspond one-to-one with the plurality of guide holes 11 and slide in cooperation.

[0054] Preferably, both the lower mold base plate 1 and the upper mold base plate 4 are rectangular, with guide holes 11 located at the four corners of the lower mold base plate 1 and guide pillars 12 located at the four corners of the upper mold base plate 4. In this embodiment, when the mold is opened, the multiple guide pillars 12 are separated from the multiple guide holes 11; when the mold is closed, the multiple guide pillars 12 are inserted into the multiple guide holes 11.

[0055] This facilitates the movement of the lower mold base plate 1 and the upper mold base plate 4 towards each other, moving away from or closer to each other, thereby improving the accuracy of mold closing and opening.

[0056] Furthermore, a sprue seat 61 is fixed inside the sprue. When the mold is closed, the sprue sleeve 6 is fitted onto the sprue seat 61. The sprue seat 61 has a notch on the side near the lower mold insert 2, and the sprue sleeve 6 communicates with the cavity through the notch.

[0059] Preferably, the cooling water connector 15 extends horizontally out of the upper mold base plate 4, and the cooling water connector 15 and the cooling ring 14 can be connected by threads.

[0060] During die casting, after the molten metal is injected through the sprue sleeve 6, it is connected to external cooling water through the cooling water connector 15. The cooling water is then introduced into the annular cooling tank to cool the metal inside the sprue sleeve 6, which facilitates pressure maintenance inside the cavity.

[0062] Preferably, the lower slag bag extension block 16 has a groove on its upper side and the upper slag bag extension block 17 has a groove on its lower side. The grooves of the lower slag bag extension block 16 and the upper slag bag extension block 17 together form a slag-containing cavity.

[0063] During die casting, the pressure of the molten metal pushes the air in the mold cavity into the slag cavity, and the air is discharged through the gap between the lower slag extension block 16 and the upper slag extension block 17. The slag formed by the molten metal that first enters the mold cavity is also pushed into the slag cavity by the subsequent molten metal, which facilitates the removal of defects caused by segregation and uneven crystallization, and improves the die casting quality of the mounting plate workpiece 100.

[0066] The support foot 18 guides the ejector pin fixing assembly, ensuring that the ejector pin fixing assembly uniformly drives multiple ejector rods 13 to move up and down relative to the lower mold base plate 1, which facilitates the ejector rods 13 to uniformly eject the mounting plate workpiece 100 when the mold is opened.

[0067] Furthermore, the ejector pin fixing assembly includes an ejector pin fixing plate 19, through which the ejector rod 13 passes; an ejector pin baffle 20 is provided on the lower side of the ejector rod 13 fixing plate, and the ejector pin baffle 20 is connected to the ejector pin fixing plate 19 by screws.
