Description

Technical Field

[0001] The invention relates to the technical field of low-pressure casting molds, and in particular provides a low-pressure casting mold for a multi-row ultrasonic equipment base. Background Art

[0002] Low-pressure casting is a casting method that applies low pressure to molten metal to slowly enter the mold and cool it into shape. Although this method can achieve a higher quality of finished products, it still has some technical defects in practical applications, especially for multi-row ultrasonic equipment bases with complex structures. First, the mold design is often complicated, which makes the demolding process difficult. Especially in the multi-row structure, the stress distribution inside the mold is uneven, which makes the casting easily damaged during demolding.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. By adopting modular design, the mold can quickly adapt to the needs of different products, which not only simplifies the mold manufacturing process, but also improves the flexibility and maintainability of the mold, simplifies the maintenance process, and reduces the scrap rate in production. When it is necessary to produce ultrasonic equipment bases of different shapes or sizes, only the corresponding modules need to be replaced without redesigning the entire mold. The assembly and disassembly of the mold becomes simpler and faster, thereby improving casting efficiency, and it is easy to clean and maintain, thereby comprehensively improving the performance and production efficiency of the mold.

[0016] 2. By arranging an ejection assembly in the lower mounting seat, utilizing the precise coordination and interaction of the sliding wedge, the ejector rod and the ejection block, and driving the ejector rod forward through an external power device, the sliding wedge can be driven to slide forward inside the ejection groove. At this time, the ejection block arranged at the front end of the sliding wedge will move upward along the ejection hole, and then eject the lower mold body out of the mold body groove, thereby achieving a smooth and precise ejection action, being able to simply and quickly realize the demolding under the mold, effectively avoiding product damage during the demolding process, and improving casting efficiency and product quality.

[0017] 3. The side sealing of the cavity by the forming sleeve effectively prevents the casting liquid from deflecting downward under the action of gravity, thereby avoiding deformation of the lower side of the casting. At the same time, considering the possible shrinkage of the casting during the cooling and molding process, the driving cylinder in the side demoulding assembly can adaptively push the forming sleeve to compensate for this shrinkage deformation, ensure the stability of the side wall of the casting during the cooling and molding process, and improve the flatness of the side wall of the casting, that is, improve the dimensional accuracy and shape stability of the casting. In addition, a second spring is provided on the abutting surface of the driving cylinder, and the second spring can generate relative elastic force on the pushing plate and the forming sleeve, so that the forming sleeve can better adapt to changes in the casting molding process.

[0018] 4. By arranging an ejector assembly at the bottom of the mold, an ejector plate at the top, and the first module, the third module, the fourth module and the side demoulding assembly driven by the cylinder around, the operator only needs to drive the corresponding cylinder and push the ejector rod, and cooperate with the mechanical linkage of the upper sliding assembly and the ejector assembly to achieve rapid demoulding and assembly of various components, reducing manual intervention, reducing labor intensity, and improving the level of production automation. It also helps to reduce scratches and damage on the surface of the casting through smooth and precise demoulding action, thereby improving the quality of the casting.

The base 10 is a square plate, the lower die base 20 is arranged on the base 10, the upper die base 30 and the lower die base 20 are arranged opposite to each other, and the cavity 40 is located between the upper die base 30 and the lower die base 20; the first module 41 and the second module 42 are both concave blocks and are arranged relatively parallel to each other. The first module 41 and the second module 42 are respectively arranged on the two short side surfaces of the cavity 40, the third module 43 and the fourth module 44 are both rectangular blocks and are arranged relatively parallel to each other. The third module 43 and the fourth module 44 are respectively arranged on the two long side surfaces of the cavity 40.

[0032] Specifically, the mold of the present invention is mainly composed of four parts, namely, a lower mold base 20, an upper mold base 30, a first module 41, a second module 42, a third module 43 and a fourth module 44, which together surround a mold cavity 40. This modular design enables the mold to quickly adapt to the needs of different products, which not only simplifies the manufacturing process of the mold, but also improves the flexibility and maintainability of the mold, simplifies the maintenance process, and reduces the scrap rate in production. When it is necessary to produce ultrasonic equipment bases of different shapes or sizes, it is only necessary to replace the corresponding modules without redesigning the entire mold. The assembly and disassembly of the mold becomes simpler and faster, thereby improving the casting efficiency, and is easy to clean and maintain, thereby comprehensively improving the performance and production efficiency of the mold.

[0033] like Figure 1 , 3 As shown, the lower mold base 20 includes a lower mounting base 21, a lower mold body 22 and an ejection assembly 23. The lower mounting base 21 is connected to the base 10 through a plurality of studs. A mold body groove 211 and two sets of guide block grooves 212 are provided on the top of the lower mounting base 21. The two sets of guide block grooves 212 are respectively located on both sides of the mold body groove 211. The depth of the mold body groove 211 is greater than the depth of the guide block groove 212. The lower mold body 22 is arranged in the mold body groove 211. An ejection groove 213 is provided on the bottom of the lower mounting base 21 near the second module 42. The lower mounting base 21 is also provided with a rectangular groove 213.

The ejection assembly 23 includes a sliding wedge block 231, a push rod 232 and an ejection block 233. The sliding wedge block 231 is close to the ejection groove 213. The upper side of the end is beveled and provided with a push inclined surface. The push rod 232 is fixedly arranged in the sliding wedge block 231. The lower side of one end of the ejection block 233 is beveled and provided with a bevel that matches the push inclined surface. The rectangular cross-section size of the ejection block 233 is the same as the cross-section size of the ejection hole 214.

[0034] Specifically, the mold body groove 211 and the guide block groove 212 opened on the top of the lower mounting seat 21 provide precise positioning for the installation of the lower mold body 22 and other components arranged above the lower mounting seat 21, ensuring the precise matching and molding accuracy of the mold. The lower mounting seat 21 adopts the ingenious design of the mold body groove 211 and the guide block groove 212, which not only ensures the stable installation of the lower mold body 22, but also enhances the structural strength of the mold through the depth difference. The ejection assembly 23 realizes a smooth and precise ejection action by utilizing the precise matching and interaction of the sliding wedge block 231, the ejector rod 232 and the ejection block 233. It can effectively avoid product damage during the demolding process and improve casting efficiency and product quality.

[0035] In one embodiment, an ejection assembly 23 is provided under the lower mounting seat 21. After the low-pressure casting is completed, the external power equipment pushes the ejector rod 232 forward, which can drive the sliding wedge block 231 to slide forward inside the ejection groove 213. At this time, the ejection block 233 provided at the front end of the sliding wedge block 231 will move upward along the ejection hole 214, and then eject the lower mold body 22 out of the mold body groove 211, so that the demolding under the mold can be realized simply and quickly.

[0036] like Figure 1 , 3 As shown, the upper mold base 30 includes an upper mounting base 31, an upper mold body 32, an ejector plate 33 and a fixing plate 34. The cross-sectional size of the upper mounting base 31 is equal to the cross-sectional size of the lower mounting base 21. The upper mold body 32 is arranged inside the upper mounting base 31. Four support guide pillars 311 are arranged on the wide surface of the upper mounting base 31 away from the mold cavity 40. The four support guide pillars 311 are respectively arranged at four diagonal positions close to the upper mounting base 31. A plurality of ejector holes 31 are also opened through the upper mounting base 31 and the upper mold body 32. 2. Four needle plate guide pillars 331 and a plurality of ejector rods 332 are vertically arranged on the ejector plate 33. The ejector plate 33 is connected to the upper mounting seat 31 through the four needle plate guide pillars 331. The plurality of ejector rods 332 are arranged in one-to-one correspondence with the plurality of ejector holes 312. The plurality of ejector rods 332 are arranged in the upper mounting seat 31 and the upper mold body 32 through the corresponding plurality of ejector holes 312.

The ejector plate 33 is stably connected to the upper mounting base 31 through four needle plate guide pillars 331, ensuring the precise guidance and smooth movement of the ejector rod 332 during the ejection process. The one-to-one correspondence between multiple ejector holes 312 and ejector rods 332 not only helps the mold forming, but also improves the stability of the cavity 40, and can also make the ejection force evenly distributed, effectively improving the demolding efficiency and integrity of the product.

[0038] In one embodiment, a plurality of ejector rods 332 are arranged on the ejector plate 33 to abut against the lower mold body 22. After the casting is completed, an ejection force is applied to the ejector plate 33, and the lower end of the ejector rod 332 can push the casting out of the mold cavity 40, so that the demolding above the mold can be realized simply and quickly, making the demolding process faster and smoother. At the same time, the damage to the mold and the casting during the demolding process is reduced, the service life of the mold is extended, and the integrity and precision of the casting are ensured. In addition, the setting of the fixed plate 34 provides additional safety protection to prevent the ejector rod 332 from accidentally popping out under high pressure, thereby protecting the safety of the operator.

[0042] Specifically, the second U-shaped block 431 and the third U-shaped block 441 are used in conjunction with the corresponding cylinders and telescopic columns to enhance the lateral support and stability of the third module 43 and the fourth module 44, and reduce the possibility of deformation during the casting process. The setting of the second cylinder 432 and the third cylinder 442 can realize automatic ejection action, improve production efficiency, and provide a sliding connection between the L-shaped guide rail 434 and the convex guide block 221, which provides precise guidance and positioning, ensuring the precise closing and opening of both sides of the mold.

The inclined surface slide rail 66 is connected with an L-shaped third support rod 67 on the side wall close to the side slide rail 61. The other end of the third support rod 67 is connected to the side wall of the side slide rail 61. The upper slide rod 68 is fixedly connected to the side wall of the inclined surface slider 65 in an upward direction compared to the horizontal plane.

[0046] The upper slide rod 68 includes a fourth support rod 681 and an upper top block 682. The fourth support rod 681 is arranged parallel to the horizontal plane. The upper top block 682 is a rectangular block with a flat bottom and an inclined top. One end of the fourth support rod 681 is fixedly connected to the inclined slide block 65, and the other end of the fourth support rod 681 is vertically fixedly connected to the bottom plane of the upper top block 682. An upper top opening 683 is opened on the upper side of the base 10 to allow the upper top block 682 to extend out.

[0047] Specifically, the mechanical linkage structure of the upper sliding assembly 60 and the ejection assembly 23 can realize the smooth conversion of the upper sliding rod 68 from driving to ejection through the cooperation of multiple parts. And the inclined top structure of the upper ejector block 682 on the upper part of the upper sliding rod 68 can more effectively apply the ejection force during the sliding process to ensure the smooth demolding of the product from the mold. In addition, the upper sliding assembly 60 is integrally embedded in the lower mounting seat 21 and is tightly connected to the ejection assembly 23, which not only optimizes the internal space utilization of the mold, but also enhances the stability and durability of the structure.

[0048] In one embodiment, a space capable of accommodating the movement of the upper sliding assembly 60 is provided inside the lower mounting seat 21, and a limiting slide for the active sliding block 611 is provided on the side of the sliding wedge block 231. Therefore, when the external power equipment pushes the top rod 232 forward, it will simultaneously drive the active sliding block 611 to move forward along the side slide rail 61. At this time, the active sliding block 611 drives the first support rod 62, and the first support rod 62 drives the driven sliding block 63 to move forward together. Due to the limitation of the third support rod 67, the driven sliding block 631 will also slide forward along the driven sliding block 63, and the inclined sliding block 65 connected to the driven sliding block 631 through the second support rod 64 will slide upward along the inclined sliding rail 66 along the trend of the driven sliding block 631 sliding forward, thereby driving the upper sliding block 68 fixedly connected to the inclined sliding block 65 to gradually move upward as a whole, and finally causing the upper ejecting block 682 to be ejected through the upper ejecting opening 683.

[0049] like Figure 4 and Figure 7-8 As shown, in one embodiment, the present invention also includes a side demolding assembly 70, which includes a forming sleeve 71, a pushing plate 72, a driving rod 73 and a driving cylinder 74. The side demolding assembly 70 is arranged as a whole between the second module 42 and the cavity 40. The forming sleeve 71 is clamped between the inner wall edges opposite to each other of the third module 43 and the fourth module 44, and forms a side seal for the cavity 40. The forming sleeve 71 is a U-shaped plate composed of a long side plate and a short side plate, and a fitting gap is formed between the long side plate and the short side plate. The pushing plate 72 is fitted with the forming sleeve 71 and is located in the fitting gap. A first spring 731 is fixedly provided at one end of the driving rod 73. The driving rod 73 is provided with one end of the first spring 731 and is vertically connected to the middle of the pushing plate 72. The driving cylinder 74 is arranged at the other end of the driving rod 73 away from the pushing plate 72.

[0050] The push plate 72 is provided with a spring groove 721 in the middle of the side in contact with the forming sleeve 71, and a second spring 722 connected to the inner wall of the push plate 72 is fixedly arranged in the spring groove 721, and the other end of the second spring 722 is connected to the forming sleeve 71. The push plate 72 is provided with a stripping groove 723 in the middle of the lower part of the side close to the third module 43, and the side length of the stripping groove 723 is equal to the side length of the forming sleeve 71.

[0051] In one embodiment, during the casting process, the casting formed by cooling the molding liquid is affected by the effects of thermal expansion and contraction during the cooling and molding process, and the upper side will shrink inward to a certain extent, while the lower side will deviate outward to a certain extent due to the influence of gravity, which may cause the lower side of the casting to undergo a downward trapezoidal deformation. The side sealing of the cavity 40 by the molding sleeve 71 effectively prevents the casting molding liquid from deviating downward under the action of gravity, thereby avoiding the deformation of the lower side of the casting. At the same time, considering the possible shrinkage of the casting during the cooling and molding process, the driving cylinder 74 in the side demolding assembly 70 can adaptively advance the molding sleeve 71 to compensate for this shrinkage deformation, thereby ensuring the stability of the side wall of the casting during the cooling and molding process, and improving the flatness of the side wall of the casting, that is, improving the dimensional accuracy and shape stability of the casting. In addition, a second spring 722 is provided on the abutting surface of the driving cylinder 74. The second spring 722 can generate relative elastic force on the pushing plate 72 and the forming sleeve 71, so that the forming sleeve 71 can better adapt to the changes in the casting molding process, which can not only improve the molding accuracy, but also enhance the connection stability between the forming sleeve 71 and the pushing plate 72, so that the forming sleeve 71 can have a certain buffering and resetting ability when subjected to external force, thereby better adapting to various changes in the casting molding process and reducing the deformation of the casting during the molding process.

[0052] In one embodiment, the side demolding assembly 70 as a whole is used to cooperate with the second module 42 to form the side shape of the cavity 40, and can also be used to quickly demold the side. The demolding process is as follows: first, the third module 43 and the fourth module 44 are ejected to both sides. When the external power equipment pushes the ejector rod 232, the upper ejector block 682 is ejected through the upper ejection port 683. The length of the short side of the upper ejector block 682 is set to be less than or equal to the length of the short side of the molding sleeve 71. At this time, the top of the inclined surface of the upper ejector block 682 will push a corner of the molding sleeve 71 upward, causing the molding sleeve 71 to rotate upward and to the right. The continuous torsional force causes the long side plate in the molding sleeve 71 to rotate upward and to the right, thereby causing the short side plate that was originally engaged with the push plate 72 to gradually deviate. At this time, a separation gap is generated between the forming sleeve 71 and the push plate 72, and the second module 42 of the side demoulding assembly 70 will be outwardly disengaged during the demoulding process, so that the second spring 722 originally compressed in the push plate 72 will be extended and popped out from the spring groove 721. The second spring 722, which was originally in a compressed state, begins to gradually release energy and exerts a reverse elastic force on the forming sleeve 71. This elastic force not only helps the forming sleeve 71 to be more smoothly disengaged from the push plate 72, but also helps the forming sleeve 71 to return to the initial fitting position after the demoulding, so as to prepare for the next mold use. The second spring 722 not only provides the power required for demoulding, but also buffers the impact force during the demoulding process, so that the separation of the forming sleeve 71 and the push plate 72 is smoother, reducing damage to the mold and the product. During the demolding process, as the forming sleeve 71 is gradually lifted and twisted, its lower part will extend into the demolding groove 723 below the push plate 72. The design of the demolding groove 723 provides sufficient space for the deflection of the forming sleeve 71, avoiding damage to the mold or operating difficulties caused by deflection. At the same time, the existence of the demolding groove 723 also makes the entire demolding process smoother and more controllable. At this time, the side demolding assembly 70 can be smoothly removed from the mold and opened to realize the demolding work on the side of the mold, which can facilitate subsequent mold cleaning, casting removal and other operations. The structural design of the side demolding simplifies the demolding operation, reduces manual intervention, reduces labor intensity, and improves the level of production automation. The smooth and precise demolding action helps to reduce scratches and damage on the surface of the casting, thereby improving the quality of the casting. When demolding is completed, the operator uses an external power device to hold the U-shaped lower end of the forming sleeve 71, forcing its lower end to be removed from the demolding groove 723, and then pushes it forward to re-engage the push plate 72 with its fitting gap, thereby completing the resetting of the side demolding assembly 70 for the next use.

[0053] The present invention can achieve:

[0054] 1. The overall modular design enables the mold to quickly adapt to the needs of different products, which not only simplifies the mold manufacturing process, but also improves the flexibility and maintainability of the mold, simplifies the maintenance process, and reduces the scrap rate in production. When it is necessary to produce ultrasonic equipment bases of different shapes or sizes, only the corresponding modules need to be replaced without redesigning the entire mold. The assembly and disassembly of the mold becomes simpler and faster, thereby improving casting efficiency, and is easy to clean and maintain, thereby comprehensively improving the performance and production efficiency of the mold.

[0055] 2. The mold body groove 211 and the guide block groove 212 opened on the top of the lower mounting seat 21 provide accurate positioning for the installation of the lower mold body 22 and other components arranged above the lower mounting seat 21, ensuring the precise matching and molding accuracy of the mold. The lower mounting seat 21 adopts the ingenious design of the mold body groove 211 and the guide block groove 212, which not only ensures the stable installation of the lower mold body 22, but also enhances the structural strength of the mold through the depth difference. The ejection assembly 23 realizes a smooth and accurate ejection action by utilizing the precise matching and interaction of the sliding wedge block 231, the ejector rod 232 and the ejection block 233, which can effectively avoid product damage during the demoulding process and improve casting efficiency and product quality.

[0056] 3. The design of guiding the liquid in the lower mold body 22 through two liquid injection conduits 51 and corresponding liquid injection ports 52 can realize accurate distribution of the liquid in the mold cavity 40, ensure the uniform flow and filling of the liquid during the casting process, improve the density and uniformity of the casting, help reduce defects inside the casting, such as pores, inclusions, etc., and improve the overall quality of the casting. In addition, the liquid injection conduit 51 runs through the base 10 and the lower mounting seat 21, optimizes the liquid flow path, reduces the flow resistance, improves the liquid flow efficiency, reduces the casting cycle time, and improves production efficiency.

[0057] 4. The mechanical linkage structure of the upper sliding assembly 60 and the ejection assembly 23 can realize the smooth conversion of the upper sliding rod 68 from driving to ejection through the coordinated work of multiple components. The inclined top structure of the upper ejector block 682 on the upper sliding rod 68 can more effectively apply the ejection force during the sliding process to ensure that the product is smoothly demolded from the mold. In addition, the upper sliding assembly 60 is integrally embedded in the lower mounting seat 21 and is tightly connected to the ejection assembly 23, which not only optimizes the internal space utilization of the mold, but also enhances the stability and durability of the structure.

[0058] 5. The side sealing of the cavity 40 by the forming sleeve 71 effectively prevents the casting liquid from deflecting downward under the action of gravity, thereby avoiding the deformation of the lower side of the casting. At the same time, considering the shrinkage of the casting during the cooling and molding process, the driving cylinder 74 in the side demolding assembly 70 can adaptively push the forming sleeve 71 to compensate for this shrinkage deformation, ensure the stability of the side wall of the casting during the cooling and molding process, and improve the flatness of the side wall of the casting, that is, improve the dimensional accuracy and shape stability of the casting. In addition, a second spring 722 is provided on the abutting surface of the driving cylinder 74, and the second spring 722 can generate relative elastic force on the pushing plate 72 and the forming sleeve 71, so that the forming sleeve 71 can better adapt to changes in the casting molding process.

[0059] 6. By arranging the ejector assembly 23 at the bottom of the mold, the ejector plate 33 at the top, and the first module 41, the third module 43, the fourth module 44 and the side demolding assembly 70 driven by the cylinders around, the operator only needs to drive the corresponding cylinders and push the ejector rod 232, and cooperate with the mechanical linkage of the upper sliding assembly 60 and the ejector assembly 23 to realize the rapid demolding and assembly of various components, thereby reducing manual intervention, reducing labor intensity, and improving the level of production automation. It also helps to reduce scratches and damage on the surface of the casting through a smooth and precise demolding action, thereby improving the quality of the casting.
