Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, and in particular to a casting forming mold device that is easy to disassemble. Background Technology

[0002] Casting molds are the core components of the casting process. They define the shape, dimensional accuracy, and surface quality of the casting. Essentially, they are precision and durable cavities used to hold molten metal and remove the solid casting after the metal solidifies and cools. They are relatively low in cost, highly flexible, and suitable for single-piece, small-batch, and large-scale casting production. The molds themselves are durable, and the casting process is simple. They are widely used in the manufacturing of automotive parts and aerospace structural components.

[0003] To safely and quickly remove cooled solid castings, various easy-to-disassemble casting mold devices have been put into use. Most existing easy-to-disassemble casting mold devices adopt an ejection structure, using ejector pins and push plates to push the casting away from the cavity and core. The ejection structure can quickly remove the casting, but the ejector pin head directly contacts the surface of the casting, which will inevitably leave indentations on the casting. When the ejector pins are not properly arranged, the ejection force is too large, or the casting itself is not strong enough, stress concentration is very likely to occur near the contact point of the ejector pins, resulting in local deformation and dents in the casting.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 5 This utility model provides an embodiment of a casting mold device that is easy to disassemble, comprising a threaded rod 1, a baffle 11 fixedly connected to the outer wall of the threaded rod 1 near its edge, a gear 32 fixedly connected to the top of the threaded rod 1, a chain 12 meshing with the outer wall of the gear 32, a gear 5 meshing with the inner wall of the chain 12, an end plate 30 rotatably connected to the upper middle part of the outer wall of the threaded rod 1, a rear side plate 28 fixedly connected to the rear side of the end plate 30, a box top plate 31 fixedly connected to the top of the rear side plate 28, and a servo motor fixedly connected to the top of the box top plate 31. 3. A motor protective shell 4 is fixedly connected to the outer wall of the servo motor 3. Multiple end plates 10 are fixedly connected to the front side of the rear side plate 28. A guide rail 6 is fixedly connected to the inner wall of the end plate 10. A slider 7 is slidably connected to the lower middle part of the outer wall of the guide rail 6. Limiting posts 8 are rotatably connected to the middle of the left and right sides of the slider 7. Limiting blocks 13 are fixedly connected to the left and right sides of the slider 7 near the edge. An upper mold 9 is slidably connected to the inner wall of the slider 7. A box bottom plate 27 is fixedly connected to the bottom of the rear side plate 28. A demolding mechanism 2 is provided at the bottom of the upper mold 9. The demolding mechanism 2 is used for convenient and quick demolding of the module.

[0033] Specifically, the servo motor 3 drives the gear 2 5 to rotate, which in turn drives the gear 1 32 and the threaded rod 1 to rotate synchronously through the chain 12, giving the device a more efficient power system. The rotation of the threaded rod 1 causes the slider 7 to slide up and down along the guide rail 6, realizing the lifting and lowering of the upper mold 9, which increases the efficiency and safety of demolding the upper part of the casting. The design of the slider 7, end plate 1 30, and end plate 2 10 can lock the position of the upper mold 9, enhancing the stability of the device. The cooperation of the limiting post 8 and the limiting block 13 allows the upper mold 9 to be more stably fixed on the slider 7 and aligned with the lower mold 205, improving the stability and accuracy of the device.

[0034] Please see the appendix Figure 4 and attached Figure 6The demolding mechanism 2 includes a lower mold 205, the top of which fits against the bottom of the upper mold 9. A rectangular groove 201 is fixedly connected to the bottom of the lower mold 205. A semi-circular groove 202 is fixedly connected to the bottom of the inner wall of the rectangular groove 201. A semi-circular locking block 208 is rotatably connected to the middle of the inner wall of the rectangular groove 201. A rotating rod 204 is fixedly connected to the outer wall of the semi-circular locking block 208. Multiple threaded holes 207 are provided at the bottom of the rectangular groove 201. Screws 203 are threadedly connected to the inner wall of the threaded holes 207. A limit groove 206 is provided at the top of the box bottom plate 27.

[0035] Specifically, the rectangular groove 201 provides an installation base for the lower mold 205. The semi-circular groove 202 at its bottom cooperates with the semi-circular locking block 208. The locking and unlocking of the lower mold 205 is achieved by the contact and separation of the two. The rotating rod 204 can drive the semi-circular locking block 208 to rotate. When the semi-circular locking block 208 is in contact with the semi-circular groove 202, it can lock the position of the lower mold 205. When the two are separated and the groove of the semi-circular locking block 208 is aligned with the groove of the lower mold 205, the lower mold 205 can be separated to the left and right, which facilitates the demolding of the casting. The threaded hole 207 cooperates with the screw 203 to fix the rectangular groove 201 at the limiting groove 206 of the bottom plate 27, ensuring that the demolding mechanism 2 is more stable as a whole.

[0036] Please see the appendix Figure 1 and attached Figure 6 A storage bin 25 is fixedly connected to the top of the top plate 31 of the box. A bin cover 26 is installed on the upper part of the storage bin 25. A discharge port 16 is opened at the bottom of the storage bin 25. A material injection pipe 15 is connected to the inner wall of the discharge port 16. A material injection valve 14 is connected to the inner wall of the material injection pipe 15. A box support leg 22 is fixedly connected to the bottom of the bottom plate 27 of the box. Ventilation plates 20 are fixedly connected to both the left and right sides of the top plate 31 of the box. Push-pull rods 18 are fixedly connected to the opposite sides of the multiple ventilation plates 20.

[0037] Specifically, the storage hopper 25, hopper lid 26, discharge port 16, injection pipe 15, and injection valve 14 work together to make the material conveying of the device more convenient and adjustable. The box support legs 22 are fixed to the bottom of the box base plate 27 to provide stable support for the entire device and prevent shaking during operation. The ventilation plate 20 and push-pull rod 18 can promote air circulation inside the device, help dissipate heat and make it easier for operators to push and pull the device, improving the ease of movement.

[0038] Please see the appendix Figure 1 and attached Figure 2A motor switch 19 is fixedly connected to the left side of the ventilation panel 20 near the edge. A hinge 21 is rotatably connected to the front of the ventilation panel 20. A protective shell 17 is fixedly connected to the top left of the top of the box top plate 31. A hook 29 is fixedly connected to the right side of the ventilation panel 20 near the edge. A box door panel 24 is rotatably connected to the front of the hinge 21. A handle 23 is fixedly connected to the front of the box door panel 24.

[0039] Specifically, the motor switch 19 facilitates the start, stop, and forward / reverse rotation of the servo motor 3, enabling the mold to lift and lower. The hinge 21 connects the ventilation plate 20 and the door panel 24, allowing the door panel 24 to rotate around the hinge 21. This, combined with the handle 23, allows for the opening and closing of the device, facilitating the inspection of the internal structure. The protective shell 17 is located on the left side of the top plate 31, protecting the gears and chain 12. The hook 29 on the right ventilation plate 20 can be used to hang tools or accessories, improving operational convenience.

[0040] Working principle: When the casting mold device is working normally, the upper mold 9 is embedded in the slider 7. The limiting post 8 is rotated to be parallel with the limiting block 13, thereby fixing the upper mold 9. The forward rotation motor switch 19 is turned on, and the servo motor 3 drives the gear 5 to rotate, which in turn drives the chain 12, gear 32, and threaded rod 1 to rotate gradually, so that the slider 7 slides down along the guide rail 6 until the upper mold 9 is in close contact with the lower mold 205. The forward rotation motor switch 19 is then turned off. After the casting is formed, the reverse rotation motor switch 19 is turned on, so that the slider 7 slides up along the guide rail 6 until the upper mold 9 is in close contact with the upper end plate 10. The reverse rotation motor switch 19 is then turned off, so that the casting remains in the lower mold 205, making the demolding of the upper mold safer and faster.

[0041] The demolding mechanism 2 is used for quick demolding of the casting in the lower mold 205. After the upper mold 9 slides upward, the rotating rod 204 is adjusted through the hole below the limiting groove 206 to drive the semi-circular locking block 208 to rotate. When the joint of the two semi-circular locking blocks 208 rotates to coincide with the joint of the lower mold 205, the lower mold 205 can be separated to the left and right, so that the casting can be demolded quickly.
