Description

Technical Field

[0001] This utility model relates to the field of casting molds, specifically a disassembly and assembly mold for casting steel parts. Background Technology

[0002] Cast steel parts refer to parts or components obtained by pouring molten steel into a mold through the casting process, and then cooling and solidifying them. Before casting, the upper and lower molds need to be spliced ​​together to obtain the required cavity. Then, molten iron is poured into the cavity, and after cooling, it is demolded.

[0003] Current cast steel molds, as described in patent CN221473446U, include a mold body, the interior of which is filled with cast steel sand, and a mold cover is installed at the upper end of the mold body. A feed pipe is installed through the upper surface of the mold cover. A heat dissipation mechanism is provided on the outside of the mold body. The heat dissipation mechanism includes a spiral tube and a water supply mechanism. The spiral tube is installed on the outside of the mold body.

[0004] The inventors believe that the water pump in the heat dissipation mechanism, via a first and second water pipe, delivers cooling water from the water tank to the spiral tube. The cooling water flows within the spiral tube, dissipating heat from the mold body. This water-cooling method can significantly improve the molding speed of circular cast steel parts. However, during the casting process, the mold temperature is usually high. When water passes through the spiral tube, some of it rapidly evaporates to form steam, causing a sharp increase in pressure within the spiral tube, thus increasing the risk of the spiral tube exploding. Utility Model Content

[0005] The purpose of this utility model is to provide a disassembly and assembly mold for casting steel parts, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A disassembly and assembly mold for casting steel parts, comprising:

[0008] A casting mechanism, comprising a lower mold, an upper mold adapted to the lower mold above the lower mold, and a casting pipe connected to the interior of the upper mold fixedly connected to the top of the upper mold;

[0009] The cooling mechanism includes cooling cavities formed inside the lower mold and the upper mold. Both sides of the lower mold and the upper mold have through holes communicating with the interior of the cooling cavities. A guide rod is symmetrically fixedly connected to one side of the lower mold. Trapezoidal blocks are slidably connected to the outer sides of both sets of guide rods. Springs are fixedly connected between the two sets of trapezoidal blocks and the lower mold. A three-way pipe is fixedly connected between the two sets of trapezoidal blocks. Multiple interconnected guide pipes are uniformly fixedly connected to the top of the three-way pipe. An upper pipe and a lower pipe are fixedly connected to the side of each set of guide pipes closest to the lower mold. The upper pipe and the lower pipe correspond to the two sets of through holes on one side. Push rods corresponding to the two sets of trapezoidal blocks are symmetrically fixedly connected to one side of the upper mold.

[0010] As a further embodiment of this utility model: both sides of the lower mold and the upper mold are symmetrically fixedly connected with extension blocks, and the two sets of extension blocks on the upper side are symmetrically rotatably connected with bolts, and the two sets of extension blocks on the lower side are symmetrically provided with threaded holes that are compatible with the bolts.

[0011] As a further embodiment of this utility model: multiple reinforcing ribs are uniformly fixedly connected to the top of each group of extension blocks, the reinforcing ribs of each group on the lower side are fixedly connected to the lower mold, and the reinforcing ribs of each group on the upper side are fixedly connected to the upper mold.

[0012] As a further embodiment of this utility model: a limiting block is fixedly connected to the end of each of the two sets of guide rods away from the lower mold, and the limiting block abuts against the trapezoidal block.

[0013] As a further embodiment of this utility model: the bottom of both sets of push rods is rotatably connected to rollers, and the rollers correspond to the trapezoidal blocks.

[0014] As a further embodiment of this utility model: the inner wall of the cooling cavity is uniformly and fixedly connected with multiple fins, and each set of lower tubes corresponds to the area between two adjacent fins.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] With the above-described structure, this invention, through the cooperation of the cooling chamber, through holes, tee pipe, and trapezoidal block, allows the push rod to move downwards with the lower mold until it contacts the top of the trapezoidal block. This causes the trapezoidal block, tee pipe, and guide pipe to move to one side of the lower mold. When the upper mold moves downwards and comes into contact with the lower mold, each set of lower pipes extends into the lower cooling chamber, while each set of upper pipes extends into the upper cooling chamber. The tee pipe is then connected to a water source, allowing water to drain into each set of guide pipes. Water is then discharged into the upper and lower cooling chambers through the upper and lower pipes, respectively, thus cooling the lower and upper molds. When water enters the cooling chamber, the high temperature of the molten steel causes the water to evaporate rapidly, carrying away heat and forming a large amount of water vapor. This water vapor can be discharged through the through holes on both sides, reducing the risk of excessive pressure and explosion inside the cooling chamber. Attached Figure Description

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] Please see Figure 1-4A casting mold for steel casting includes a casting mechanism 1, which includes a lower mold 101 and an upper mold 102 above the lower mold 101. A casting pipe 103, communicating with the interior of the upper mold 102, is fixedly connected to the top of the upper mold 102. The casting pipe 103 facilitates the injection of molten steel into both the lower and upper molds. Extension blocks 104 are symmetrically fixedly connected to both sides of the lower and upper molds 101 and 102. Multiple reinforcing ribs 105 are uniformly fixedly connected to the top of each set of extension blocks 104. The lower sets of reinforcing ribs 105 are fixedly connected to the lower mold 101, and the upper sets of reinforcing ribs 105 are fixedly connected to the upper mold 102. The reinforcing ribs 105 further connect and fix the upper mold 102 to the extension blocks 104.

[0025] Both upper sets of extension blocks 104 are symmetrically connected to bolts 106 through their interiors. Both lower sets of extension blocks 104 are symmetrically provided with threaded holes 107 that mate with the bolts 106. The threaded holes 107 are for screwing the bolts 106 into, thereby fixing the lower mold 101 and the upper mold 102. Cooling mechanism 2 includes cooling chambers 201 located inside the lower mold 101 and the upper mold 102. The cooling chambers 201 are for containing water, allowing the water to cool either the lower mold 101 or the upper mold 102 after being drained into them, thus cooling the molten steel inside the lower mold 101 and the upper mold 102.

[0026] Both sides of the lower mold 101 and the upper mold 102 have through holes 203 that communicate with the interior of the cooling cavity 201. The through holes 203 facilitate the drainage of water into the cooling cavity 201 and the discharge of water vapor. Guide rods 204 are symmetrically fixedly connected to one side of the lower mold 101. Trapezoidal blocks 207 are slidably connected to the outer sides of both sets of guide rods 204. The guide rods 204 guide the sliding of the trapezoidal blocks 207. Springs 206 are fixedly connected between the two sets of trapezoidal blocks 207 and the lower mold 101. Limiting blocks 205 are fixedly connected to the ends of the two sets of guide rods 204 away from the lower mold 101. The limiting blocks 205 abut against the trapezoidal blocks 207, limiting the sliding of the trapezoidal blocks 207 and reducing the probability of the trapezoidal blocks 207 disengaging from the outer sides of the guide rods 204.

[0027] A three-way pipe 208 is fixedly connected between each of the two sets of trapezoidal blocks 207. Multiple interconnected guide pipes 209 are evenly fixedly connected to the top of each three-way pipe 208. The three-way pipe 208 is used to drain water, allowing water to flow into the interior of each set of guide pipes 209. An upper pipe 211 and a lower pipe 210 are fixedly connected to the side of each set of guide pipes 209 closest to the lower mold 101. The upper pipe 211 and lower pipe 210 can respectively guide water into the interior of the upper and lower cooling chambers 201.

[0028] The upper tube 211 and lower tube 210 correspond to two sets of through holes 203 on one side, respectively. A push rod 212 corresponding to two sets of trapezoidal blocks 207 is symmetrically fixedly connected to one side of the upper mold 102. Rollers 213 are rotatably connected to the bottom of each push rod 212, corresponding to the trapezoidal blocks 207. The push rods 212 and rollers 213 are designed to move synchronously up and down with the upper mold 102, so that when the rollers 213 move downwards, they can push the trapezoidal blocks 207 to one side of the lower mold 101, thereby allowing the lower tube 210 and upper tube 211 to extend into the cooling chamber 201. Multiple fins 202 are uniformly fixedly connected to the inner wall of the cooling chamber 201. Each set of lower tubes 210 corresponds to the area between two adjacent fins 202. The fins 202 facilitate heat conduction, thereby facilitating rapid heat dissipation for the lower mold 101 and the upper mold 102.

[0029] In use, the upper mold 102 is moved downwards until it abuts against the lower mold 101. Then, each set of bolts 106 is screwed into the threaded holes 107, thereby fixing the lower mold 101 and the upper mold 102. When the upper mold 102 moves downwards, it can drive the push rod 212 and the roller 213 to move downwards as well. When the roller 213 moves downwards and contacts the top of the trapezoidal block 207, it can roll along the top of the trapezoidal block 207, thereby driving the trapezoidal block 207, the three-way pipe 208, and each set of guide pipes 209 to move to one side of the lower mold 101, so that each set of lower pipes 210 extends into the interior of the lower cooling cavity 201, and each set of upper pipes 211 extends into the upper cooling cavity 201. The molten steel is then poured into the mold grooves inside the lower mold 101 and upper mold 102 through the casting pipe 103. After that, the three-way pipe 208 is connected to the water source, so that the water is discharged into the interior of each set of guide pipes 209. Then, the water is discharged into the interior of the upper and lower cooling chambers 201 through each set of upper pipes 211 and each set of lower pipes 210, thereby cooling the lower mold 101 and upper mold 102. When the water is discharged into the interior of the cooling chamber 201, due to the high temperature of the molten steel, the water evaporates rapidly, taking away the heat and forming a large amount of water vapor. This water vapor can be discharged into the interior of the cooling chamber 201 through the through holes 203 on both sides, thereby reducing the risk of explosion caused by excessive pressure inside the cooling chamber 201.

[0030] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
