Description

Technical Field

[0001] The invention relates to the technical field of metal casting equipment, and in particular to a die-casting molding equipment for metal blank processing. Background Art

[0002] Metal blank processing is widely used in the fields of automobile manufacturing, aerospace, electronic equipment and mechanical parts, and is an indispensable part of modern industrial production. In these fields, the quality and production efficiency of metal parts directly affect the performance and cost of the final product. Therefore, how to efficiently and accurately manufacture high-quality metal parts has become a research focus.

[0003] As an efficient and precise metal forming process, die casting has gradually attracted widespread attention and application. Die casting equipment quickly injects molten metal into the mold cavity under high pressure, allowing it to cool and solidify in a short time to form the desired part shape. This process not only enables efficient mass production, but also has high surface quality, good dimensional accuracy, and relatively high material utilization of the molded parts. Therefore, die casting technology has been widely used in industries such as automobiles, home appliances, and electronic equipment.

[0004] In the die-casting process, the use of release agents is an important step to ensure smooth demolding of products, improve product surface quality and extend mold life. The existing technology mainly includes several common methods, including manual coating, automatic spraying and roller coating. Although the manual coating method is highly flexible, it has low operating efficiency and is not suitable for mass production. Although automatic spraying equipment improves production efficiency, its high cost and maintenance complexity limit its application in small and medium-sized enterprises. In addition, the existing coating methods often need to be adjusted when dealing with different mold shapes and sizes, which increases production preparation time and reduces overall production efficiency.

[0028] In summary, the present invention mainly has the following beneficial effects:

[0029] 1. High coating precision to ensure uniform demoulding:

[0030] By setting up the first coating plate and the second coating plate, combined with the precise control of the moving parts, the release agent can be evenly coated on the side wall of the mold cavity, ensuring that the entire cavity surface is fully covered. Even when the shape of the mold cavity changes, the coating part can still accurately spray the release agent, further improving the demoulding effect and reducing surface defects caused by poor demoulding.

[0031] 2. Save release agent and reduce material waste:

[0032] During the spraying process of the release agent, the coating part is sprayed only when the coating plate moves to the preset position, and the spraying stops immediately after leaving the preset position. This precise control method effectively reduces the waste of release agent and ensures that the release agent is only coated in the necessary area, thereby reducing production costs and improving material utilization.

[0033] 3. Improve production efficiency and adapt to mass production:

[0034] This equipment significantly improves production efficiency by automatically controlling the operation of moving parts and coating parts. Compared with the traditional manual coating method, it reduces the possibility of human intervention and operating errors, and is suitable for large-scale production needs. In addition, the automated design of the equipment also reduces the dependence on the operator's skill level, making the production process more stable and efficient.

[0035] 4. Extend mold life and reduce maintenance costs:

[0036] Since the release agent can be evenly and fully coated on the mold surface, it effectively reduces the adhesion between the casting and the mold, and reduces the wear and corrosion of the mold. This not only extends the service life of the mold, but also reduces the maintenance cost of frequent mold replacement, thereby further improving the economic efficiency of the equipment.

[0037] 5. Strong adaptability and flexible application:

[0038] The equipment design takes into account the changes in different mold shapes and sizes. By adjusting the position and operation mode of the coating plate and spray parts, it can flexibly adapt to various die-casting process requirements. This allows the equipment to be used not only in standardized production, but also in diversified and personalized production needs.

[0039] In summary, the precise control and efficient application of the die-casting equipment in the release agent coating process significantly improves the quality and production efficiency of castings, reduces material waste and mold wear, and thus provides a more optimized solution for the metal blank processing technology.

DETAILED DESCRIPTION

[0056] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] refer to Figure 1-Figure 11 , a die-casting molding equipment for metal blank processing, comprising:

[0058] Die casting frame 100;

[0059] A base 101 is provided on the die casting frame 100, and a top plate 102 is provided on the die casting frame 100;

[0060] A lower mold 103 is disposed on the base 101, an upper mold 104 is disposed on the top plate 102, and a cavity 105 is formed on the upper mold 104 and the lower mold 103;

[0061] A first coating plate 106 is disposed on the base 101 , a second coating plate 107 is disposed on the first coating plate 106 , and the second coating plate 107 is located at the bottom of the upper mold 104 ;

[0062] A box 108 is provided on the die-casting frame 100, and the box 108 is filled with a release agent;

[0063] A moving component provided on the die casting frame 100, used to move the position of the top plate 102 up and down;

[0064] A conveying component provided between the box 108 and the first coating plate 106 and the second coating plate 107, for conveying the release agent into the first coating plate 106 and the second coating plate 107;

[0065] The coating components provided on the first coating plate 106 and the second coating plate 107 are used to spray the release agent on the side wall of the cavity 105;

[0066] Wherein, the moving component can move the positions of the first coating plate 106 and the second coating plate 107 when moving the top plate 102 up and down;

[0067] The coating component can spray the release agent onto the side wall of the cavity 105 when the first coating plate 106 and the second coating plate 107 move to the first preset position, and stop spraying the release agent when leaving the second preset position;

[0068] Wherein, the conveying component can convey the release agent into the first coating plate 106 and the second coating plate 107 when the top plate 102 moves downward;

[0069] By setting the upper mold 104 and the lower mold 103, the upper mold 104 can be fixed on the top plate 102 by a detachable method such as bolts, and the lower mold 103 can be fixed on the base 101 during application. During die-casting, the operator can start the moving component, and the moving component moves the position of the top plate 102 downward, so that the top plate 102 drives the upper mold 104 thereon to move downward. When the moving component moves the position of the top plate 102 downward, the position of the first coating plate 106 and the second coating plate 107 can also be moved, so that the first coating plate 106 and the second coating plate 107 can slide between the upper mold 104 and the lower mold 103. In addition, when the top plate 102 moves downward, the conveying component can convey the release agent into the first coating plate 106 and the second coating plate 107, so that a certain pressure is generated in the first and second coating plates 107, and the first and second coating plates 106 and 107 are pressed against each other. 107 moves to the first preset position, that is, when the first and second coating plates 107 slide to the position of the cavity 105 at the bottom of the upper mold 104 and the top of the lower mold 103, the coating component can spray the release agent on the side wall of the cavity 105. When the first and second coating components leave the second preset position, that is, when the first and second coating plates 107 leave the position of the cavity 105, the coating component stops spraying the release agent to avoid waste of the release agent, so as to ensure that the release agent is accurately coated only in the necessary area and at the necessary time. The first coating plate 106 and the second coating plate 107 are controlled by the moving component to accurately slide to the predetermined position to ensure that the release agent is evenly and effectively sprayed on the side wall of the mold cavity 105, thereby improving the demoulding effect and reducing surface defects of the casting. Through the coating component set, even when the shape of the cavity 105 changes, it can also be sprayed accurately.

[0070] As a further solution of the present invention, the coating component includes a connecting cavity 200 opened in the first coating plate 106 and the second coating plate 107, and a coating port 201 connected to the connecting cavity 200 is opened at the bottom of the first coating plate 106 and the top of the second coating plate 107. A connecting pipe 202 is slidably sleeved in the coating port 201, and a nozzle 203 is arranged in the connecting pipe 202. A first spring 204 is connected between the connecting pipe 202 and the connecting cavity 200, and a bracket 205 is arranged in the connecting pipe 202. A connecting rod 206 is connected to the bracket 205, and a connecting port 207 is provided at the bottom of the first coating plate 106 and the top of the second coating plate 107. A top contact rod 208 is slidably connected in the connecting port 207. The top contact rod 208 extends into the connecting cavity 200 and is connected to the connecting rod 206. A second spring 209 is connected to the top contact rod 208 and the connecting cavity 200. A piston 210 slidably connected to the bracket 205 is connected in the connecting cavity 200, and the piston 210 is adapted to the liquid inlet of the nozzle 203.

[0071] By setting the first spring 204, the first spring 204 can limit the position of the connecting tube 202, and the piston 210 can close the bracket 205 to ensure that the liquid does not enter the nozzle 203 in the initial position. When the first coating plate 106 and the second coating plate 107 are moving, the top contact rod 208 can contact the surface of the upper mold 104 and the lower mold 103, and is restricted by the position. The top contact rod 208 is forced to move, and the bracket 205 can be displaced through the connecting rod 206. When the bracket 205 leaves the piston 210, the connecting tube 202 is restricted by the position of the upper mold 104 and the lower mold 103 and also starts to displace, so that the nozzle 203 in the connecting tube 202 and the piston 210 can be sleeved and sealed again. With the nozzle 203 closed, when the first coating plate 106 and the second coating plate 107 are displaced to the position of the cavity 105 on the surfaces of the upper mold 104 and the lower mold 103, the top-touch rod 208 is still restricted by the positions of the upper mold 104 and the lower mold 103 to maintain the current position, and some of the connecting tubes 202 corresponding to the position of the cavity 105 among the multiple connecting tubes 202 are reset by the force of the first spring 204. At this time, the bracket 205 is opened, and the release agent in the connecting cavity 200 can enter the nozzle 203 to spray the release agent on the cavity 105. At this time, as the release agent enters the cavity 105 through the nozzle 203 and is evenly sprayed on the side wall of the cavity 105, the entire coating process can be achieved with high efficiency and precision. When the first coating plate 106 and the second coating plate 107 continue to move along the surface of the upper mold 104 and the lower mold 103 and leave the position of the cavity 105, the top contact rod 208 begins to return to the original position due to being separated from the surface of the upper mold 104 and the lower mold 103. At this time, under the action of the second spring 209, the top contact rod 208 pushes the connecting rod 206, so that the bracket 205 is again tightly fitted with the piston 210, closing the inlet of the nozzle 203, and preventing the release agent from continuing to spray, thereby avoiding material waste and ensuring that the release agent is only applied at the required position. In addition, this design avoids complex electronic control systems by utilizing the mechanical linkage between the mold and the coating component, thereby reducing the maintenance difficulty and failure rate of the equipment. At the same time, since the contact between the coating component and the mold only occurs at critical moments during the coating process, the wear on the mold is also minimized, extending the service life of the mold. Through this mechanical linkage automation design, the entire release agent coating process is more efficient, environmentally friendly, and adaptable, which can significantly improve the processing quality of metal blanks and the overall performance of die-casting molding equipment.

[0072] As a further solution of the present invention, the first coating plate 106 is connected to a first tube 211, the first tube 211 is connected to a second tube 212, and a third spring 213 is connected between the first coating plate 106 and the second coating plate 107;

[0073] By setting the third spring 213, the third spring 213 can support the position of the second coating plate 107 so that there is a certain gap between the second coating plate 107 and the first coating plate 106. The first tube 211 and the second tube 212 can allow the first coating plate 106 and the second coating plate 107 to be connected to ensure that when the release agent enters the second coating plate 107, it can enter the first coating plate 106 through the first tube 211 and the second tube 212. When the top plate 102 drives the upper mold 104 to move downward, the first coating plate 106 and the second coating plate 107 move in parallel at the same time, so that the second coating plate 107 can slide on the first coating plate 106 and avoid the position of the upper mold 104 to ensure that when the second coating plate 107 moves in parallel, it can also contact the lower surface of the upper mold 104. The third spring 213 between the first coating plate 106 and the second coating plate 107 provides a certain elastic support , so that the second coating plate 107 can automatically adjust according to the position of the upper mold 104 during the process of contacting the upper mold 104. Due to the connection design of the first tube 211 and the second tube 212, when the release agent enters the second coating plate 107 through the conveying component, the release agent will also flow into the first coating plate 106 through the first tube 211 and the second tube 212, thereby ensuring that both coating plates can obtain sufficient release agent reserves and are ready for spraying. When the upper mold 104 and the lower mold 103 are completely closed, the first coating plate 106 and the second coating plate 107 can completely leave the lower mold 103 and the lower mold 103, ensuring that the process of spraying the release agent is only carried out in the key area. Through this design, the first coating plate 106 and the second coating plate 107 can not only accurately control the spraying of the release agent during the die-casting process, but also can perform flexible adaptive adjustments during the movement of the top plate 102, thereby realizing an efficient and stable production process.

[0074] As a further solution of the present invention, the moving component includes two first screw rods 300 rotatably connected to the die casting frame 100, the top plate 102 is threadedly connected to the first screw rods 300, a first chain transmission mechanism 301 is connected between the two first screw rods 300, a motor 302 is connected to the die casting frame 100, and a second chain transmission mechanism 303 is connected between the driving shaft of the motor 302 and one of the first screw rods 300;

[0075] By setting a motor 302, the drive shaft of the motor 302 drives one of the first screw rods 300 to rotate through the second chain transmission mechanism 303. When the motor 302 is started, the first screw rod 300 rotates, and the top plate 102 threadedly connected thereto also moves up and down. Since the two first screw rods 300 are connected by the first chain transmission mechanism 301, the two first screw rods 300 are ensured to rotate synchronously, thereby ensuring that the top plate 102 remains horizontal during the movement, avoiding the problem of tilt or offset caused by uneven force distribution.

[0076] As a further solution of the present invention, the conveying component includes an air injection cavity 400 and a liquid cavity 401 opened in the box body 108, the release agent is filled in the liquid cavity 401, a push plate 402 is slidably connected in the air injection cavity 400, a first opening 403 is opened on the push plate 402, a second opening 404 is opened between the air injection cavity 400 and the liquid cavity 401, a one-way valve mechanism 405 is provided in the first opening 403 and the second opening 404, a threaded pipe 406 is connected to the bottom of the push plate 402, a second screw 407 threadedly connected to the threaded pipe 406 is rotatably connected in the air injection cavity 400, the second screw 407 is a reciprocating screw, and a hose 408 is connected between the liquid cavity 401 and the second coating plate 107;

[0077] By setting the liquid cavity 401, when used, the liquid cavity 401 can be closed, and the second screw rod 407 can be rotated. The rotation of the second screw rod 407 can move the position of the push plate 402 upward, and when the push plate 402 moves upward to the limit position, it starts to return and move downward, and in this way, when the push plate 402 moves upward, the one-way valve in the first opening 403 on the push plate 402 is closed, and the one-way valve in the second opening 404 opened between the gas injection cavity 400 and the liquid cavity 401 is closed, and the push plate 402 can push the gas in the gas injection cavity 400 into the liquid cavity 401. When the push plate 402 moves downward, the one-way valve mechanism 405 in the second opening 404 is closed, and the one-way valve mechanism 405 in the first opening 403 is opened, so that gas can be transported into the gas injection cavity 400, so as to facilitate the next gas injection into the liquid cavity 401. As the amount of gas in the body 401 increases, the pressure in the liquid cavity 401 can be increased. As the pressure in the liquid cavity 401 increases, the release agent will be subjected to a higher compression force in the liquid cavity 401, and the release agent will be delivered to the second coating plate 107 through the hose 408. Through this design, a stable supply of release agent can be guaranteed. The setting of the one-way valve mechanism 405 allows the gas to flow in one direction, avoiding the backflow of gas when the push plate 402 is reset, ensuring the effectiveness and stability of each gas injection process. This design uses mechanical force to drive the delivery of liquid without relying on electrical equipment, reducing the complexity and maintenance cost of the system, and also reducing the dependence on power supply, making the entire system more stable and reliable, ensuring a stable and controllable supply of release agent, saving energy, avoiding possible electrical failures, and improving the reliability and durability of the system.

[0078] As a further solution of the present invention, a first synchronous wheel 409 is connected to the first screw rod 300, a second synchronous wheel 410 is connected to the second screw rod 407, and a ratchet mechanism 411 is provided between the first synchronous wheel 409 and the first screw rod 300;

[0079] By setting a ratchet mechanism 411, when the first screw rod 300 rotates to move the top plate 102 downward, the second screw rod 407 can be rotated by the ratchet mechanism 411 to pressurize the liquid cavity 401, and the mold release agent is transported into the first coating plate 106 and the second coating plate 107. When the nozzle 203 is turned on, the mold release agent will be accurately sprayed onto the side wall of the mold cavity through the nozzle 203 under pressure to ensure smooth demolding of the casting surface. After the work is completed, the first screw rod 300 can be driven in reverse to rotate, so that the top plate 102 drives the upper mold 104 to leave the lower mold 103 for demolding. The ratchet mechanism 411 can allow the first screw rod 300 to idle in the first synchronous wheel 409 to prevent the second screw rod 407 from being driven in reverse, thereby avoiding unnecessary pressurization of the liquid cavity 401 during the rising process of the top plate 102. Through this ratchet mechanism 411, the system realizes efficient energy transmission and control, ensuring that the release agent can be accurately controlled throughout the die-casting and demolding process. At the same time, this design also reduces the pressure burden on the liquid cavity 401 and the conveying system during the reverse operation, prolongs the service life of the equipment, and improves the reliability and work efficiency of the overall system. The entire process does not require complex electrical equipment, and efficient and stable release agent delivery and control can be achieved through purely mechanical means, greatly simplifying the maintenance and operating costs of the equipment.

[0080] As a further solution of the present invention, the one-way valve mechanism 405 includes a connecting pipe 412 connected to the first opening 403 and the second opening 404, an air intake pipe 413 is slidably connected to the connecting pipe 412, an air intake port 414 is formed on the outer wall of the air intake pipe 413, and a fourth spring 415 is connected between the air intake pipe 413 and the connecting pipe 412;

[0081] By setting the connecting pipe 412, in the initial state, the air inlet port 414 on the air inlet pipe 413 is in the connecting pipe 412, and when the push plate 402 moves upward, the connecting pipe 412 in the first opening 403 can limit the position of the air inlet pipe 413 to ensure that the gas does not overflow from the connecting pipe 412 in the first opening 403. After the pressure in the gas injection cavity 400 increases, the air inlet pipe 413 in the connecting pipe 412 in the second opening 404 can be forced to move, and when the air inlet port 414 enters the liquid cavity 401, the gas can be injected into the liquid cavity 401 to achieve the purpose of pressurizing the liquid cavity 401. This design ensures that the gas can be evenly distributed in the liquid cavity 401, thereby ensuring the stable delivery of the release agent.

[0082] As a further solution of the present invention, a slide plate 304 is slidably connected to the bottom of the base 101, and a third screw rod 305 threadedly connected to the slide plate 304 is rotatably connected to the inner bottom surface of the die-casting frame 100, and the third screw rod 305 is a reciprocating screw rod. A traction rope 306 is connected to one side of the slide plate 304, and one end of the traction rope 306 is connected to the first coating plate 106, and passes through the first coating plate 106, bypasses the base 101, and is connected to the other side of the slide plate 304;

[0083] By setting the third screw rod 305, when in use, the third screw rod 305 can be rotated, and the rotation of the third screw rod 305 can move the slide plate 304, and the sliding movement can use the traction rope 306 to move the position of the first coating plate 106. After the upper mold 104 and the lower mold 103 are buckled to close the cavity 105, the rotation of the first screw rod 300 can be stopped, and the rotation of the third screw rod 305 is also stopped at the same time. The slide plate 304 moves to the extreme position of the third screw rod 305, and the first coating plate 106 and the second coating plate 107 move to the extreme position on the right. During the resetting process of the top plate 102 and the upper mold 104, when the first screw rod 300 rotates in the opposite direction to move the top plate 102 upward, the third screw rod 305 will not rotate, which avoids the additional movement of the slide plate 304 and the coating plate, and the first coating plate 106 and the second coating plate 107 maintains its current position during the retraction of the top plate 102 and the upper mold 104. This design can ensure that the coating plate will not be disturbed unnecessarily during the separation of the top plate 102 and the mold, thereby reducing the waste of the coating agent and improving the stability of the system. After the top plate 102 is reset upward, the first screw 300 is rotated again when the next die-casting work is carried out. At this time, the third screw 305 is rotated to allow the first coating plate 106 and the second coating plate 107 currently on the right side of the base 101 to move to the right side of the base 101, and the release agent is sprayed again to ensure that the inner wall of the mold is evenly coated. By coordinating the rotation of the first screw 300 and the third screw 305, the entire coating process can maintain consistency and high precision, thereby improving the overall efficiency of die-casting and product quality.

[0084] As a further solution of the present invention, the first screw rod 300 is connected to a first gear 307, the third screw rod 305 is connected to a second gear 308, and a ratchet mechanism 411 is also connected between the first gear 307 and the first screw rod 300;

[0085] By setting the ratchet mechanism 411, when the first screw rod 300 rotates, the first gear 307 can be rotated through the ratchet mechanism 411, and the first gear 307 can rotate the third screw rod 305 through the second gear 308, so as to achieve the purpose of moving the slide plate 304 through the traction rope 306 to move the first coating plate 106 and the second coating plate 107. After the die-casting work is completed, the first screw rod 300 is reversely rotated to reset the top plate 102 and the upper mold 104 upward. The design of the ratchet mechanism 411 can effectively avoid the rotation of the first gear 307, thereby preventing the synchronous rotation of the third screw rod 305. Since the first gear 307 does not rotate, the second gear 308 and the third screw rod 305 also remain stationary. This means that the position of the slide plate 304 will not change, and the traction rope 306 and the first coating plate 106 and the second coating plate 107 connected thereto will also remain in their current positions. In this process, the first coating plate 106 and the second coating plate 107 are not disturbed and can stay stably at their extreme positions. This design effectively avoids the accidental movement of the coating plate during the retraction of the top plate 102 and the upper mold 104, thereby preventing unnecessary waste of the release agent and ensuring the stability and efficiency of the system. When the top plate 102 is fully reset, the system is ready for the next die-casting operation. At this time, the operator rotates the first screw 300 in the forward direction again, and the ratchet mechanism 411 will re-transmit the rotational force to the first gear 307, thereby driving the third screw 305 to rotate, so that the slide plate 304 moves. This mechanism not only ensures that the coating plate is stationary during the mold reset process, but also ensures that the movement of each component of the entire system in each operation cycle is consistent and high-precision, thereby improving the overall efficiency and product quality of die-casting.

[0086] As a further solution of the present invention, the die casting frame 100 is provided with an injection system connected to the lower mold 103. The injection system of the die casting machine is a prior art and will not be described in detail herein.

[0087] By setting up an injection system, the metal material (such as aluminum, magnesium, zinc, etc.) is heated to above its melting point to make it liquid. This process is usually completed in a furnace. Before starting to inject liquid metal, ensure that the upper and lower molds 103 are correctly positioned and snapped together to form a closed mold cavity. The molten liquid metal is transported from the furnace to the injection chamber through the injection system of the die-casting machine. The injection chamber quickly pushes the liquid metal into the mold cavity through a high-pressure plunger. Under high pressure, the liquid metal quickly fills the entire mold cavity and covers the internal structure of the lower mold 103. Once the liquid metal enters the mold cavity, it will begin to cool and solidify. After the liquid metal is completely solidified and forms a blank, the top plate 102 and the upper mold 104 are lifted upward by the reverse rotation of the first screw 300, thereby opening the mold cavity and completing the demolding process. During the lifting process of the top plate 102 and the upper mold 104, the first coating plate 106 and the second coating plate 107 maintain their positions unchanged, ensuring that there is no unnecessary interference during the demoulding process, preventing the waste of the coating agent, and ensuring the coating effect when used next time.

[0088] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
