Description

Technical Field

[0001] The invention relates to the technical field of pouring and processing of special-shaped steel castings, in particular to a pouring mould for special-shaped steel castings. Background Art

[0002] Special-shaped steel castings refer to steel castings with complex shapes and unconventional geometric shapes. They are usually used to meet the requirements of specific mechanical equipment or special working conditions. For example, the star-shaped multi-fork cast steel connector is one of them (such as Fig. 9 As shown in the figure, the main part of the special-shaped casting is a vertical cylinder with rectangular or trapezoidal protruding wing-like structures extending in four directions. It is often used as a connection for rotating or sliding parts in engineering machinery. The complex geometric shape of special-shaped steel castings places high demands on the casting mold.

[0003] Traditional molds are usually divided into an upper mold and a lower mold, and are placed horizontally. When pouring the star-shaped multi-forked cast steel connector, the molten metal uses its own gravity to flow horizontally along the pouring channel. Due to the general lateral fluidity of the molten metal and the complex multi-forked areas of special-shaped castings, which are far away from the main runner, the complex forked areas are often incompletely filled during the pouring process, forming cold shuts or shrinkage defects; and the traditional horizontal double-mold design also imposes certain restrictions on the cooling and heat dissipation efficiency. Since the lower half of the mold is in direct contact with the ground and the external contact area is limited, the heat dissipation is uneven during cooling, which prolongs the cooling cycle of the cast part.

[0004] In addition, due to the complex surface of special-shaped castings, the traditional double-mold design results in a large contact area between the mold and the special-shaped casting, especially in the area of ​​the multi-fork structure. The friction and sticking resistance increase during the demolding process, and a large thrust force is required, which can easily cause scratches, deformation, and even damage to the casting surface. Summary of the invention

[0005] The present invention provides a casting mold for special-shaped steel castings, which solves the problem that the traditional mold usually consists of an upper mold and a lower mold, and the horizontal placement design has obvious defects when casting the star-shaped multi-fork cast steel connecting seat. Due to the poor lateral fluidity of the molten metal, the complex multi-fork area of ​​the special-shaped casting is far away from the main runner, resulting in incomplete filling during the casting process, which is easy to form cold shut or shrinkage defects. At the same time, the lower part of the mold is in contact with the ground, and the external heat dissipation area is limited. The heat distribution is uneven during cooling, which prolongs the cooling cycle. In addition, the double-mode mold has a large contact area with the casting, and the friction and sticking resistance increase during demoulding, which is easy to cause scratches, deformation or damage to the casting surface.

[0006] The present invention provides a casting mold for special-shaped steel castings, comprising a base and a mounting through hole opened in the middle of the base, wherein a plurality of quick-disassembly mold mechanisms for quick demolding after casting and molding are equidistantly arranged on the upper part of the base in the circumferential direction, wherein a synchronous mold closing and disassembling control mechanism is arranged in the mounting through hole and between the quick-disassembly mold mechanism, wherein the synchronous mold closing and disassembling control mechanism is used for synchronously closing and disassembling multiple quick-disassembly mold mechanisms so as to simultaneously cast and eject multiple castings, wherein a wrap-type cooling portion for quick cooling of the castings is arranged outside the quick-disassembly mold mechanism, wherein a connecting unit for connecting adjacent wrap-type cooling portions is arranged between two adjacent quick-disassembly mold mechanisms, wherein the connecting unit is used for connecting the wrap-type cooling portions to each other so that the wrap-type cooling portions can work in coordination to cool the quick-disassembly mold mechanism synchronously, and wherein the quick-disassembly mold mechanism is arranged vertically to enhance the fluidity of molten steel during casting and ensure that the molten steel is quickly poured and filled into the quick-disassembly mold mechanism.

[0010] In one possible implementation, the male head includes a conical tube head connected to the end of the cooling tube, and the outer wall of the conical tube head is fixedly connected with a plurality of sealing plug rings equidistantly along its own axis.

[0034] See also Figure 1 , Figure 2 and Figure 4In this embodiment, the quick-disassembly mold mechanism 3 includes a slide groove group 1 31 provided on the upper end surface of the base 1 and perpendicular to the axis of the mounting through hole 2, and two slide groove groups 32 symmetrically provided on the upper end surface of the base 1 and perpendicular to the slide groove group 1 31. The slide groove groups 32 are both slidably connected to the main mold base 33 through the slider 2. The two main mold bases 33 are symmetrically distributed. The slide groove group 1 31 is slidably connected to the supporting mold base 34 cooperating with the main mold base 33 through the slider 1. The main mold base 33 and the supporting mold base 3 A casting mold cavity is commonly provided inside, a gate 35 communicating with the casting mold cavity is provided on the upper part of one main mold base 33, a riser communicating with the casting mold cavity is provided on the upper part of the other main mold base 33, a hydraulic telescopic rod 1 36 corresponding to the position of the main mold base 33 is symmetrically fixedly connected to the upper end surface of the base 1 through a fixing plate, a C-shaped plate 37 is fixedly connected to the back sides of the two main mold bases 33, and the telescopic section end of the hydraulic telescopic rod 1 36 is fixedly connected to the outer side of the C-shaped plate 37 corresponding to it.

[0035] See also Figure 4 , Figure 5 and Figure 6 A rectangular groove 7 is provided on one side of the main mold base 33 near the supporting mold base 34, and sliding grooves are provided on the upper and lower groove walls of the rectangular groove 7. A strip sliding block 8 is slidably connected in the sliding groove, and a pressure column 9 is fixedly connected between the upper and lower strip sliding blocks 8, and a top spring group 10 is fixedly connected between the strip sliding block 8 and the sliding groove. A pushing strip 11 with a wedge-shaped cross section that cooperates with the pressure column 9 is symmetrically fixedly connected on one side of the supporting mold base 34 near the rectangular groove 7, and a rectangular strip 12 is fixedly connected on one side of the supporting mold base 34 near the main mold base 33. A C-shaped groove 13 that cooperates with the rectangular strip 12 is provided on one side of the main mold base 33 near the supporting mold base 34, and the corresponding two C-shaped grooves 13 openings are opposite to each other.

[0036] See also Figure 2 The synchronous mold closing and disassembly control mechanism 4 includes a hydraulic telescopic rod 2 41 fixedly connected to the installation through hole 2 through a support rod and a column shaft 42 fixedly connected to the upper end of the hydraulic telescopic rod 2 41, and a plurality of lugs 1 corresponding to the position of the mold support base 34 are fixedly connected at equal intervals on the circumferential outer wall of the column shaft 42, and a lug 2 is fixedly connected to the side of the mold support base 34 close to the column shaft 42, and a push-pull rod 43 is hinged between the lug 2 and the lug 1.

[0037] In the initial state, the main mold base 33 and the supporting mold base 34 are both located in a mutually separated position, and the push-pull rod 43 is in an inclined state with a side higher near the column axis 42 and a side lower away from the column axis 42. When it is necessary to cast a special-shaped casting, first control the hydraulic telescopic rod 1 36 to move the C-shaped plate 37, and then the C-shaped plate 37 pushes the two main mold bases 33 to move closer to each other until the two main mold bases 33 are butted against each other, and then control the hydraulic telescopic rod 2 41 to move the column axis 42 downward, and the column axis 42 drives the push-pull rod 43 to move downward and outward at the same time, and then the push-pull rod 43 pushes the supporting mold base 34 to move outward until the supporting mold base 34 contacts the main mold base 33. At this time, the casting cavity between the main mold base 33 and the supporting mold base 34 forms a whole, and the push-pull rod 43 becomes horizontal. The coordinated combination of the push-pull rod 43 and the column axis 42 is used to achieve synchronous tightening and clamping of multiple supporting mold bases 34.

[0038] When the supporting mold base 34 moves toward the main mold base 33, it will drive the pushing strip 11 to move synchronously. When the pushing strip 11 enters the rectangular groove 7, the inclined surface of the pushing strip 11 will touch the pressure column 9, and then squeeze the pressure column 9, so that the two pressure columns 9 located in the quick-release mold mechanism 3 move closer to each other, and the pressure column 9 then drives the bar sliding block 8 to move, and the bar sliding block 8 then pushes the top spring group 10 to be compressed, exerting pressure on the corresponding two main mold bases 33, further making the corresponding two main mold bases 33 tightly touch each other; at the same time, when the two main mold bases 33 move and dock together, the C-shaped grooves 13 will also be driven to dock together, so that the two corresponding C-shaped grooves 13 form a rectangular shape, and when the supporting mold base 34 moves and contacts the main mold base 33 next, the supporting mold base 34 will drive the rectangular strip 12 to move and embed into the two C-shaped grooves 13 forming a rectangular shape, thereby further enhancing the sealing and connection strength of the two main mold bases 33 and the supporting mold base 34 when docking, and ensuring the casting accuracy.

[0039] After the docking is completed, the molten steel can be poured into the pouring gate 35, and then the molten steel flows into the casting mold cavity. After the casting is completed, the molten steel can be cooled and formed. Through the vertical arrangement of the main mold base 33 and the supporting mold base 34, gravity is used to enhance the fluidity of the molten steel to ensure uniform filling of the casting mold cavity.

[0040] After the poured molten steel is cooled and formed, the hydraulic telescopic rod 2 41 is controlled to operate again to drive the column shaft 42 to move downward, and the column shaft 42 then drives the push-pull rod 43 which has become horizontal to move downward, and the push-pull rod 43 then pulls the supporting mold base 34 toward the column shaft 42 to separate the supporting mold base 34 from the main mold base 33, and then the two hydraulic telescopic rods 1 36 are controlled to operate to pull the two main mold bases 33 away from each other, so that the casting can be removed, and the demolding operations of multiple castings can be completed at one time. The supporting mold base 34 and the two main mold bases 33 cooperate with each other to achieve multi-directional demolding, while reducing the contact surface between each mold base and the casting, avoiding excessive constraints on complex geometric structures, reducing friction during demolding, and reducing damage to the surface of the casting.

[0041] Then, the hydraulic telescopic rod 1 36 can be controlled again to repeat the above steps of pushing the two main mold bases 33 closer to each other and moving them against each other, and then the hydraulic telescopic rod 2 41 can be controlled to drive the column shaft 42 to move upward, and the column shaft 42 drives the push-pull rod 43 to move upward. During the upward movement of the push-pull rod 43, the supporting mold base 34 will be pushed to move closer to the main mold base 33, that is, the above steps of moving the supporting mold base 34 toward the main mold base 33 for docking are repeated, and the main mold base 33 and the supporting mold base 34 can be quickly closed, and then the above casting operation is repeated, and then the mold is removed again. The rapid closing and removing of the molds facilitates the batch casting processing of the castings.

[0042] See also Figure 1 , Figure 4 and Figure 7 In this embodiment, the wrapped cooling part 5 includes a cooling tube 51 fixedly sleeved on the outside of the main mold base 33, and the cooling tube 51 is distributed in an S-shaped path. One end of the two adjacent ends of the cooling tubes 51 is connected to a male head 52, and the other end is connected to a female head 53 that cooperates with the male head 52. The end of the cooling tube 51 close to the supporting mold base 34 is also connected to the female head 53. The male head 52 includes a conical tube head 521 connected to the end of the cooling tube 51, and the outer wall of the conical tube head 521 is fixedly connected with a plurality of sealing plug rings 522 at equal distances along its own axis. The female head 53 includes a pipe sleeve 531 connected to the end of the cooling tube 51, and the inner cavity of the pipe sleeve 531 is provided with a conical groove 532 that cooperates with the conical tube head 521.

[0043] See also Figure 2 , Figure 3 and Figure 6 The connecting unit 6 includes a bending tube 61. Two adjacent mold bases 34 are fixedly connected with the bending tube 61 through a connecting rod. The proximal ends of the two bending tubes 61 are commonly connected with a telescopic tube 62. The end of the bending tube 61 away from the telescopic tube 62 is also connected with a male head 52. The upper part of the telescopic tube 62 in one of the connecting units 6 is connected with an injection pipe 63, and the lower part of the telescopic rod on which the injection pipe 63 is installed is connected with a discharge pipe 64. The injection pipe 63 and the discharge pipe 64 are distributed in a staggered manner.

[0044] When the main mold bases 33 move toward each other, they will also drive the cooling tubes 51 to move. When the two main mold bases 33 are docked, the two cooling tubes 51 will also drive the male heads 52 and the female heads 53 on their adjacent ends to be connected together. The two cooling tubes 51 respectively drive the conical tube head 521 and the tube sleeve 531 to move toward each other. When the conical tube head 521 is inserted into the tube sleeve 531, it will drive the sealing plug ring 522 to contact the conical groove 532, thereby connecting the two cooling tubes 51 together.

[0045] The mold base 34 moves toward the main mold base 33 and at the same time drives the bending tube 61 to move through the connecting rod. The bending tube 61 then drives the male head 52 to move. When the mold base 34 moves to dock with the main mold base 33, the male head 52 will be inserted into the female head 53 located at the end of the cooling tube 51 close to the mold base 34, and then the middle section of the telescopic tube 62 connected to the injection tube 63 and the discharge tube 64 will be clamped and closed, and then the fluid used for cooling is introduced into the injection tube 63 as needed. After the cooling fluid enters the injection tube 63, it flows through the telescopic tube 62, the bending tube 61, the male head 52, the female head 53, the cooling tube 51, another group of male heads 52 and female heads 53 and another cooling tube 51, and then flows into the remaining wrapped cooling part 5 through the remaining connecting units 6 in turn, and finally, it is discharged from the discharge tube 64 after passing through a circle, so that part of the casting can be quickly cooled as needed to accelerate its molding.

[0046] The vertical arrangement of the main mold base 33 and the supporting mold base 34 can also enable the surrounding surface of the mold to be more fully exposed to air or cooling medium, thereby increasing the efficiency of heat transfer. For special-shaped steel castings, the cooling speed of the castings can be uniformly accelerated, and the contact area between the mold and the outside world is significantly increased, thereby effectively improving the heat dissipation performance.

[0047] See also Figure 1-Figure 9 During operation, first, the hydraulic telescopic rod 36 is controlled to drive the two main mold bases 33 to move closer to each other for mold closing, and then the synchronous mold closing and disassembly control mechanism 4 is controlled to drive multiple mold bases 34 to move outward at the same time, until the mold base 34 contacts the main mold base 33 to complete the overall mold closing, and then the molten steel can be injected into the casting mold cavity. After pouring, at the same time, the wrapped cooling parts 5 are connected to each other through the connecting unit 6, and the cooling medium is introduced into one of the connecting units 6, and then the cooling medium flows from the remaining wrapped cooling parts 5 and the connecting units 6 in turn to cool the casting and accelerate molding, and then, the synchronous mold closing and disassembly control mechanism 4 is controlled to run again to drive the mold base 34 to move and separate from the main mold base 33, and then the hydraulic telescopic rod 36 is used to control the two main mold bases 33 to move away from each other for separation, thereby completing the demolding step, and finally the molded casting can be taken out.
