Technical Field
[0001] The present invention belongs to the technical field of stainless steel casting devices, and specifically relates to an easily demoldable mold for the production of stainless steel castings. Background Art
[0002] Casting technology is a manufacturing process that uses certain-performance raw sand, metal, or other materials as the main molding materials. By melting metal liquid and pouring it into a mold, a part with the required shape and performance is obtained after cooling and solidification. Casting technology can be divided into various types, mainly including sand casting and special casting. Sand casting is suitable for making blanks with complex shapes, especially those with complex inner cavities; it has a low cost and great process flexibility, and is widely used in the mechanical manufacturing fields such as automobiles and machine tools, such as castings of engine cylinder blocks, cylinder heads, and crankshafts; Special casting includes various methods such as centrifugal casting, low-pressure casting, differential pressure casting, pressure-boost casting, gypsum mold casting, and ceramic mold casting, each with its own characteristics. For example, low-pressure casting can fill the mold and crystallize and form at a lower pressure, and the castings have a dense structure and a smooth surface; centrifugal casting is suitable for producing tubular and ring-shaped castings.
[0003] Steel casting is a metal hot working process that involves melting steel materials into a liquid and then pouring it into a mold adapted to the shape of the required workpiece. After cooling and solidification, a steel part or blank with a certain shape, size, and performance is obtained. According to different process characteristics and application requirements, steel casting can be divided into various types, and the common ones include: sand casting, metal mold casting, pressure casting, low-pressure casting, and centrifugal casting.
[0004] Stainless steel castings refer to parts or components manufactured by casting technology using stainless steel as raw materials through processes such as melting, pouring, and cooling. They have strong corrosion resistance: stainless steel castings have excellent corrosion resistance and can be used in various harsh environments for a long time without damage; high temperature resistance: some stainless steel castings have good high temperature resistance and are suitable for working in high temperature environments; high strength: stainless steel castings have high strength, can withstand large loads, and have high economic benefits.
[0005] Currently, when producing stainless steel castings, sand casting is usually used. That is, after making a sand mold, the metal liquid is poured into the mold. After cooling and solidification, the formed metal part is removed. However, in existing production, the upper and lower molds usually need to be manually lifted and placed by workers. They usually have a certain weight, and during the moving operation, work-related injuries often occur. At the same time, when manually placing them, the accuracy is also low, and multiple placement operations are often required. Then, when casting, the mold needs to be cooled, and the cooling is often completed by air cooling, and the cooling effect is poor, which prolongs the production time required and is not conducive to production operations.

Detailed implementation manners
[0032] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0033] Example 1, please refer to Figure 1-10, the present invention provides a technical solution: an easily demouldable mold for the production of stainless steel castings, comprising: a lower mold base 1 and an upper mold base 2. A top surface of the upper mold base 2 is fixedly connected with an upper mounting seat 3, and a bottom surface of the upper mold base 2 is fixedly connected with an upper closing seat 4.

The lower mold mounting seat 19 is arranged inside the lower mold base 1, the lower casting mold 20 is arranged on a top surface of the lower mold mounting seat 19, the two fin-shaped heat dissipation frames 21 are respectively slidably arranged between two inner side walls of the lower mold mounting seat 19. The lifting component includes: a bottom lifting seat 22, two lifting electric push rods 23, two bottom movable frames 24, two bottom limiting guide rails 25, two groups of lifting connecting rods 26, a bottom lifting plate seat 27 and two groups of lifting rods 28. The bottom lifting seat 22 is fixedly connected to an inner bottom surface of the lower mold base 1, the two lifting electric push rods 23 are respectively installed on two inner side walls of the bottom lifting seat 22, the two bottom movable frames 24 are respectively installed at output ends of the corresponding bottom movable frames 24, the two bottom limiting guide rails 25 are fixedly connected to a top surface of the bottom lifting seat 22, and the two bottom limiting guide rails 25 and the two bottom movable frames 24 are all in sliding fit. The two groups of lifting connecting rods 26 are respectively rotatably connected to top surfaces of the corresponding bottom movable frames 24, each group of lifting connecting rods 26 has two, the bottom lifting plate seat 27 is rotatably connected between one ends of the four lifting connecting rods 26, a demoulding opening is formed on a top surface of the bottom lifting plate seat 27, the two groups of lifting rods 28 are fixedly connected to the top surface of the bottom lifting plate seat 27, and each group of lifting rods 28 has two. The demoulding component is installed on an inner bottom surface of the lower mold base 1 for performing a demoulding operation on the lifted lower mold.
[0034] In this implementation: The upper casting mold 14 and the lower casting mold 20 are respectively arranged through the lower mold base 1 and the upper mold base 2, and are fixed and clamped by the concave clamping fixture 18. After that, stainless steel liquid is introduced into the interior of the upper casting mold 14. After it cools and forms, the upper mold 14 is driven to move upward by the upper mold adjustment assembly. At the same time, the lifting electric push rod 23 in the lifting assembly is activated, pushing the two bottom movable frames 24 to move along the bottom limiting guide rail 25, driving the lifting connecting rod 26 to move, so that the bottom lifting plate seat 27 and the lifting rod 28 move upward. Among them, the lifting rod 28 restricts the moving direction under the restriction of the mating groove 37. The upward moving lifting rod 28 will drive the lower casting mold 20 to move and separate from the lower mold mounting seat 19. At this time, the demolding assembly drives the demolding rod 38 to reciprocate up and down, knocking on the bottom surface of the lower casting mold 20, so that the formed stainless steel metal part is separated from the mold.

[0035] Specifically, the demolding assembly includes: two limit seats 30, a demolding rotating shaft 31, a pushing cam 32 and a demolding motor 33. The two limit seats 30 are both fixedly connected to the inner bottom surface of the lower mold base 1. The demolding rotating shaft 31 is rotatably connected between the outer walls of one side of the two limit seats 30. The pushing cam 32 is sleeved on the outer wall of the demolding rotating shaft 31. A motor seat is fixedly connected to the inner bottom surface of the lower mold base 1. The demolding motor 33 is installed on the top surface of the motor seat, and the output end of the demolding motor 33 is fixedly connected to one end of the demolding rotating shaft 31.
[0036] In this implementation: The demolding rotating shaft 31 is installed through the limit seat 30. The demolding rotating shaft 31 is used to drive the pushing cam 32 to rotate. The pushing cam 32 can only rotate when the lower casting mold 20 is lifted to the highest position. The rotating pushing cam 32 will periodically push the demolding rod 38 upward. The upward moving demolding rod 38 will move upward under the restraint of the demolding groove 34 and the limiting sleeve, and fall under the restraint of gravity, thus completing the reciprocating motion.
[0037] Specifically, the upper mold adjustment assembly includes: two rotating shaft seats 5, a threaded rod 6, two limiting rods 7, an upper movable frame 8 and two upper connecting rods 9. The two rotating shaft seats 5 are both fixedly connected to the top surface of the upper mold base 2. The threaded rod 6 is rotatably connected to the outer wall of one side of one of the rotating shaft seats 5, and one end of the threaded rod 6 movably penetrates through the other rotating shaft seat 5. The two limiting rods 7 are both fixedly connected between the outer walls of one side of the two rotating shaft seats 5. The upper movable frame 8 is movably sleeved on the outer wall of the threaded rod 6 through a thread. The two limiting rods 7 both movably penetrate through the upper movable frame 8. The two upper connecting rods 9 are both rotatably connected to the top surface of the upper movable frame 8.
[0038] In this embodiment: The threaded rod 6 is installed through the rotating shaft seat 5. The rotation of the threaded rod 6 drives the upper movable frame 8 to move. The limiting rod 7 restricts the movement of the upper movable frame 8 to prevent it from rotating instead of moving linearly when the threaded rod 6 rotates. The threaded rod 6 is manually rotated by the operator to avoid misoperation.
[0039] Specifically, the upper mold adjustment assembly further includes: two side lifting assemblies, the upper casting mold 14, and two extension blocks 15. Each of the two side lifting assemblies includes: two side mounting seats 10, a side movable frame 11, an upper limiting guide rail 12, two sets of lifting link rods 13, and a connecting rod. The two side mounting seats 10 are both fixedly connected to the top surface of the upper mold base 2. The upper limiting guide rail 12 is fixedly connected between the outer walls of one side of the two side mounting seats 10, and the bottom surface of the upper limiting guide rail 12 is fixedly connected to the top surface of the upper mold base 2. The side movable frame 11 is slidably sleeved on the top surface of the upper limiting guide rail 12. The top surface of the side movable frame 11 is rotatably connected to the bottom surface of the corresponding upper link rod 9. Each of the two sets of lifting link rods 13 is rotatably connected to the bottom surface of the side movable frame 11. Each set of lifting link rods 13 has two. The connecting rod is fixedly connected between the outer walls of one side of the two lifting link rods 13. The upper casting mold 14 is rotatably connected between the ends of the four lifting link rods 13. The two extension blocks 15 both extend on the outer wall of one side of the upper casting mold 14.
[0040] In this embodiment: The side lifting assemblies are used to drive the upper casting mold 14 to move up and down. The side mounting seats 10 mount the upper limiting guide rail 12, and the upper limiting guide rail 12 restricts the movement path of the side movable frame 11. The movement of the side movable frame 11 is driven by the movement of the upper link rod 9. The lifting link rods 13 move when the side movable frame 11 moves to adjust the height of the upper casting mold 14. The connecting rod is used to connect the two lifting link rods 13 to prevent dislocation or deviation. The upper casting mold 14 is used to complete the casting operation. The extension blocks 15 are used to cooperate with the inner wall of the upper mold base 2 to restrict the movement path of the upper casting mold 14 when it moves up and down.
[0041] Specifically, bottom clamping seats 16 are fixedly connected to the inner walls on both sides of the lower mold base 1. The top surfaces of the two bottom clamping seats 16 are fixedly connected to the bottom surface of the lower mold mounting seat 19.
[0042] In this embodiment: The bottom clamping seats 16 are used to install and fix the lower mold mounting seat 19 and seal the inside of the lower mold base 1 to prevent foreign objects from falling in, so as to reduce the frequency of maintenance and repair.
[0043] Specifically, clamping electric push rods 17 are installed on the inner walls of one side of the two bottom clamping seats 16. The output ends of the two clamping electric push rods 17 are both installed with concave clamping frames 18. The two concave clamping frames 18 are respectively slidably connected to the bottom surface of the corresponding bottom clamping seats 16.
[0044] In this implementation: The concave clamping frame 18 is driven to move by the clamping electric push rod 17, and the upper casting mold 14 and the lower casting mold 20 in the mold closing state are clamped and fixed by the concave clamping frame 18 to avoid gaps or misalignments therein and improve the effect of the castings produced.
[0045] Specifically, mating chamfers are provided on the inner walls of the two concave clamping frames 18, and two mating grooves 37 are provided on the top surface of the lower mold mounting base 19.
[0046] In this implementation: The mating chamfers reduce the difficulty of clamping the concave clamping frame 18, and the clamping and fixing operations can still be carried out when there is a certain offset. The mating groove 37 is used to cooperate with the concave clamping frame 18 so that it will not come into contact and collide during linear movement.
[0047] Specifically, a pressure-bearing groove 36 is provided on the top surface of the lower mold mounting base 19, and a pressure-bearing ring plate 29 is provided on the top surface of the pressure-bearing groove 36.
[0048] In this implementation: The pressure-bearing ring plate 29 is placed through the pressure-bearing groove 36, and the pressure-bearing ring plate 29 and the lower mold mounting base 19 bear the pressure of the lower casting mold 20 and the upper casting mold 14 to prevent the pressure from being borne by the lifting assembly and causing damage to it. After the upper casting mold 14 is lifted, the lifting assembly is activated, and at this time, the pressure will be borne by the lifting assembly.
[0049] Specifically, two lifting openings 35 are provided on the top surface of the lower mold mounting base 19, and the two lifting openings 35 are respectively matched with the corresponding two lifting rods 28.
[0050] In this implementation: The lifting rod 28 is accommodated through the lifting opening 35, and the outer wall of the lifting rod 28 is slidably matched with the inner wall of the lifting opening 35, which can limit the movement of the lifting rod 28 and also limit the maximum movement position of the lifting rod 28 to avoid contact and collision.
[0051] Specifically, a demolding groove 34 is provided on the top surface of the lower mold mounting base 19, a demolding rod 38 is slidably arranged between the inner walls of the demolding opening, the demolding rod 38 is matched with the demolding groove 34, a contact block is fixedly connected to the top surface of the demolding rod 38, and a limiting sleeve is movably sleeved on the outer wall of the demolding rod 38, and the top surface of the limiting sleeve is fixedly connected to the bottom surface of the lower mold mounting base 19.
[0052] In this embodiment: The demolding groove 34 is used to accommodate the demolding rod 38. The demolding rod 38 is driven by the pushing cam 32 and, under the constraint of gravity, will perform reciprocating up and down movements within the demolding groove 34. And through the limiting sleeve installed at the top, it knocks on the bottom surface of the lower casting mold 20, imitating the manual knocking of workers, improving the demolding effect and not causing damage to the lower casting mold 20. After the cooling is completed, the staff can directly remove the lower casting mold 20 to complete a casting operation.
[0053] The working principle of the present invention is as follows: The upper casting mold 14 and the lower casting mold 20 are respectively arranged through the upper mold base 1 and the upper mold base 2. The side lifting assembly drives the upper casting mold 14 to move downward, so that the upper casting mold 14 is attached to the lower casting mold 20. Then, the clamping electric push rod 17 is started to drive the concave clamping frame 18 to move, and the upper casting mold 14 and the lower casting mold 20 in the closed mold state are fixed to prevent gaps or misalignment from occurring therein. Then, liquid stainless steel is introduced through the upper casting mold 14, and the wing-shaped heat dissipation frame 21 dissipates heat from both of them. After the casting is completed, the side lifting assembly drives the upper casting mold 14 to move upward, and then the lifting assembly drives the lower casting mold 20 to move upward. At this time, the wing-shaped heat dissipation frame 21 will move upward easily with the lower casting mold 20 through the friction with the lower casting mold 20, continuously providing a heat dissipation effect. When the lower casting mold 20 moves to the highest point, the demolding assembly drives the demolding rod 38 to move to continuously knock on the lower casting mold 20, so that the formed stainless steel part is separated from the lower casting mold 20.
[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
