Technical Field

[0001] The invention relates to the field of casting, in particular to a casting mould and a casting method. Background Art

[0002] Casting is one of the earliest metal heat processing technologies mastered by humans, with a history of about 6,000 years. Casting is a method of pouring liquid metal into a casting cavity that is adapted to the shape of the part, and then cooling and solidifying it to obtain a part or blank.

[0003] In actual production, when casting with existing molds, the general process is to first snap the mold together, then pour the metal liquid into the mold cavity, then open the mold to take out the mold, and then close the mold and repeat the above steps. The overall process is time-consuming and the casting efficiency is low. Summary of the invention

[0004] The purpose of the present invention is to provide a casting mold and a casting method, which can improve the casting efficiency by alternately casting in two mold cavities.

[0034] like Figure 1-9 As shown, the casting mold is described in detail:

[0035] A casting mold comprises two support rods 102 fixed in parallel on a base frame 101, a slide 401 is slidably connected to the two support rods 102, two support shafts 402 are fixed at both ends of the slide 401, a rotating seat 502 is rotatably provided on each support shaft 402, a half mold body 501 is fixed on each rotating seat 502, and when the two half mold bodies 501 on the same side are close together and fit together, a complete mold cavity is formed, a heating furnace 201 is fixed to the middle upper end of the base frame 101, the heating furnace 201 is provided with a discharge cone pipe 202, and the discharge cone pipe 202 is symmetrically provided with two support arm rods 205 along the direction of the support rods 102, a blocking plate 203 is slidably provided on the two support arm rods 205, the blocking plate 203 is fitted on the lower end of the discharge cone pipe 202 to block the discharge cone pipe 202, and a connecting hole 204 is provided on the blocking plate 203.

[0036] Among them, an electric telescopic rod is installed between the base frame 101 and the slide 401, which is not shown in the figure and is used to control the slide 401 to slide back and forth on the two support rods 102, so that the two mold cavities are alternately moved to the bottom of the heating furnace 201 for pouring;

[0037] During casting, the casting raw material is first added into the heating furnace 201 to be heated and melted; then a pair of half mold bodies 501 are matched and moved to the bottom of the heating furnace 201 by the control of the electric telescopic rod. At this time, the two matched half mold bodies 501 form a complete mold cavity, and the upper end of the mold cavity is blocked by the blocking plate 203. Then the blocking plate 203 is controlled to slide, so that the heating furnace 201 is connected with the complete mold cavity through the connecting hole 204, and then the molten raw material flows into the complete mold cavity. After the molten raw material fills the mold cavity, the blocking plate 203 is controlled to slide to close the lower end of the discharge cone 202. After the casting in the mold cavity solidifies, the slide 401 is controlled to move, so that the other pair of half mold bodies 501 are matched and moved to the bottom of the heating furnace 201, and the above operation is repeated. At the same time, the pair of half mold bodies 501 separated from the blocking plate 203 are opened to take out the casting;

[0038] Thus, by repeating the above steps, two mold cavities are formed and alternately moved to the bottom of the heating furnace 201 for casting, and during casting, the casting is taken out in the other mold cavity, thereby improving the casting efficiency;

[0039] Moreover, the mold cavity can be opened or merged by rotating the two half mold bodies 501 on the two support shafts 402, which further facilitates the removal of the casting.

[0040] like Figure 7-9 As shown:

[0041] The rotating seat 502 is provided with a connecting shaft 503 at the end away from the half mold body 501, and a tension spring 504 is provided between the two connecting shafts 503 on the same side for automatically separating the two half mold bodies 501. A baffle plate 403 is fixed at the corresponding position of each support shaft 402 for limiting the rotation angle when the half mold body 501 is opened.

[0042] Two trapezoidal plates 105 are symmetrically fixed on both sides of the middle of the base frame 101 for automatically aligning the two half mold bodies 501 moved to the bottom of the heating furnace 201 .

[0043] At the beginning, the two half mold bodies 501 on the same side are pulled by the tension spring 504 to rotate, and press against the corresponding blocking plate 403, so that the two half mold bodies 501 are in an open state. When casting, the two half mold bodies 501 move to the bottom of the heating furnace 201 along with the slide 401. The two half mold bodies 501 first contact the two trapezoidal plates 105, and are blocked and guided by the two trapezoidal plates 105, gradually approaching until they are matched. The upper ends of the two half mold bodies 501 move to the blocking plate 203, and are again limited by the blocking plate 203 until they move to the bottom of the heating furnace 201.

[0044] After the casting is completed, the slide 401 carries the two half molds 501 away from the heating furnace 201. The two half molds 501 are first separated from the blocking plate 203, and then pulled by the tension spring 504 to press the two trapezoidal plates 105 respectively. Guided by the two trapezoidal plates 105, they are gradually opened to fully expose the casting. At this time, it is easy to remove the casting.

[0045] like Figure 1-3 As shown:

[0046] The two ends of the base frame 101 are symmetrically provided with pointed plates 103. After the two half mold bodies 501 are separated from the blocking plate 203 and automatically open, the pointed plates 103 are inserted into the gap between the two half mold bodies 501 to lift up the casting.

[0047] When the two half mold bodies 501 are separated from the blocking plate 203 and gradually opened by the pull spring 504, as the slide 401 continues to move, the tip of the pointed angle plate 103 is gradually inserted between the two half mold bodies 501, and the casting is gradually pushed upward by the inclined edge of the pointed angle plate 103, so that the casting moves upward, forming a state of complete separation from the mold cavity of the half mold body 501, making it easy to remove the casting.

[0048] Further:

[0049] A wing plate 104 is fixed to the upper end of the pointed plate 103. After the pointed plate 103 is inserted into the gap between the two half mold bodies 501 to lift the casting, the end of the wing plate 104 lifts the casting away from the inner cavity of the half mold body 501 again.

[0050] When the tip of the angled plate 103 is gradually inserted between the two half mold bodies 501, so that the casting is completely separated from the mold cavity of the half mold body 501, the casting will be in a tilted state, with one end resting on the half mold body 501 on that side. As the slide 401 continues to move, the casting contacts the wing plate 104, and is gradually pushed outward again by the oblique edge of the wing plate 104 until the casting is pushed away from the half mold body 501, completing the automatic separation of the casting.

[0051] like Figure 4-5 As shown:

[0052] Springs 206 are provided between both ends of the blocking plate 203 and the heating furnace 201 to align the lower end of the heating furnace 201 with the middle of the blocking plate 203 , and the blocking plate 203 is provided with two communicating holes 204 symmetrical about the middle.

[0053] The half mold body 501 is provided with a shift plate 505 at the end away from the heating furnace 201 .

[0054] By setting the spring 206, the plugging plate 203 can be pushed to automatically center, thereby ensuring the blocking state of the lower port of the discharge cone tube 202. When the complete mold cavity moves to the bottom of the heating furnace 201, the paddle 505 on the half mold body 501 can push the plugging plate 203 to move, so that one of the connecting holes 204 is connected to the lower port of the discharge cone tube 202, and then the casting is completed. After the casting is completed, the complete mold cavity is controlled to move in the direction in which it came. The plugging plate 203 is subject to the elastic force of the spring 206 and will move synchronously with the complete mold cavity. While completing the state of continuing to block the lower port of the discharge cone tube 202, the plugging plate 203 maintains the blocking state of the upper end of the complete mold cavity until the plugging plate 203 remains stationary and the upper port of the complete mold cavity is gradually opened. In this process, the time for the plugging plate 203 to move with the mold cavity can replace the time waiting for the liquid in the mold cavity to be formed, thereby saving time and ensuring that the mold cavity is opened only after the casting is formed, thereby ensuring the quality of the casting.

[0055] like Figure 5-6 As shown:

[0056] A partition plate 207 is fixed to the upper end of the discharge cone 202 .

[0057] It also includes a C-shaped frame 301, both ends of the C-shaped frame 301 pass through the heating furnace 201, both ends of the C-shaped frame 301 are fixed with top plates 302, the two top plates 302 are located in the heating furnace 201, a long hole plate 303 is fixed in the middle of the C-shaped frame 301, a turntable 304 is rotated on the outside of the heating furnace 201, an eccentric pin 305 is fixed at the eccentric point of the turntable 304, and the eccentric pin 305 slides in the long hole plate 303.

[0058] The side wall of the heating furnace 201 is provided with a heating device for heating the raw material, and the incompletely melted raw material is isolated by the partition plate 207 to prevent it from entering the mold cavity and affecting the quality of the casting;

[0059] The first motor installed on the heating furnace 201 drives the turntable 304, so that the turntable 304 drives the C-shaped frame 301 to move back and forth through the eccentric pin 305, driving the two top plates 302 to move back and forth, thereby forming a reciprocating stirring of the raw materials in the heating furnace 201, thereby improving the efficiency of melting the raw materials.

[0060] like Figure 1-9 As shown:

[0061] A casting method using any one of the casting molds, comprising:

[0062] S1, adding casting raw materials into the heating furnace 201 for heating and melting;

[0063] S2 After one pair of half mold bodies 501 is aligned and moved to the bottom of the heating furnace 201, the blocking plate 203 is controlled to slide so that the heating furnace 201 is connected to the complete mold cavity through the connecting hole 204, and then the molten raw material flows into the complete mold cavity;

[0064] S3, after controlling the blocking plate 203 to slide to close the lower end of the discharge cone 202, control the slide 401 to move so that the other pair of half mold bodies 501 are aligned and moved to the bottom of the heating furnace 201, and repeat step S2. At the same time, open the pair of half mold bodies 501 that are separated from the blocking plate 203 and take out the casting.

[0065] S4. Repeat step S3 to quickly obtain a casting.
