Description

Technical Field

[0001] This utility model relates to the field of lost foam mold shaping technology, specifically a lost foam mold shaping device. Background Technology

[0002] Lost foam mold shaping refers to the post-processing and correction of the foam mold (EPS or EPMMA model) during lost foam casting. This involves removing parting lines, burrs, or deformed areas from the mold using manual or mechanical methods (such as cutting tools, hot wire trimming, and sandpaper polishing) to ensure dimensional accuracy and surface finish meet casting requirements. It also repairs damaged or defective areas to prevent porosity, inclusions, or dimensional deviations in the casting caused by mold irregularities during pouring. This step directly affects casting quality and is a critical quality control point connecting mold forming with dip coating and encapsulation processes.

[0003] Currently, existing lost foam mold shaping devices typically reshape the edges and deformed areas of the lost foam mold to restore it. During use, the mold is fixed by clamping blocks, but existing clamping blocks have a strong clamping force to ensure stability, which can affect the mold. This presents a problem where the clamping structure can easily affect the lost foam mold. Furthermore, since the lost foam mold is made of foam, some foam will fall off during the shaping process, and the foam is easy to disperse, making it difficult to collect. Utility Model Content

[0025] Specifically, the upper part of the base 1 is provided with an installation groove for placing the collection plate 10, the arc top of the top block 12 supports the mold body 6, the shielding plate 4 shields the outside of the base 1, the opening of the shielding plate 4 is the operating end, and a sensor is set above the device to sense the shape of the mold body 6. The sensor is in a high position to prevent obstruction during shaping.

[0026] Please see Figures 1 to 3 A collection groove 2 is provided on the outer side of the base 1, and a baffle plate 4 is provided on the outer side of the collection groove 2. A stop block 5 is fixedly connected to the upper part of the base 1, and the inner side of the stop block 5 is in contact with the mold body 6.

[0027] Specifically, the collection trough 2 is located on the outer side of the upper part of the base 1, the baffle 5 is located in the middle of the outer side of the base 1, and the baffle 5 is in the direction of the opening of the baffle plate 4.

[0028] Please see Figures 2 to 4 The connection between the high-voltage ionization plate 9 and the base 1 is covered with insulating material. The base 1 at the bottom of the high-voltage ionization plate 9 has a heat dissipation groove. The collection plate 10 and the top block 12 are made of conductive plastic.

[0029] Specifically, the high-voltage ionization plate 9 generates static electricity that disperses upwards, and the static electricity penetrates the collection plate 10 and the top block 12, causing the static electricity to adsorb the foam.

[0030] Please see Figures 2 to 4 The groove 11 is located between multiple top blocks 12, which are distributed in a linear array. The upper end of the top block 12 is arc-shaped, and the height of the top block 12 is the same as the height of the collecting plate 10.

[0031] Specifically, the top block 12 is shaped like a square pyramid, and the lower parts of multiple top blocks 12 are in contact with each other.

[0032] Please see Figures 2 to 5 A solenoid valve 16 is fixedly connected to one side of the connector 15, and a transmission pipe of a side suction cup 17 is fixedly connected to one side of the solenoid valve 16. The position of the side suction cup 17 corresponds to the position of the central main suction cup 13.

[0033] Specifically, the solenoid valve 16 is connected to the external control structure via a wire. The solenoid valve 16 is located on both sides of the connector 15, and the side suction cup 17 and the main suction cup 13 are arranged in a cross shape.

[0034] Please see Figures 2 to 5 The main suction cup 13 is arranged in a linear array. The main suction cup 13 and the side suction cup 17 are located inside the silicone pad 7. The side suction cup 17 and the main suction cup 13 are attached to the mold body 6.

[0035] Specifically, the ends of the main suction cup 13 and the side suction cup 17 are connected to the clamping block 8.

[0036] During use, after the mold body 6 to be shaped is placed, the stop block 5 limits the mold body 6, and then the electric telescopic rod 3 is activated. The extension length of the electric telescopic rod 3 is detected by an external sensor installed at the top of the device. The external sensor detects the shape of the mold body 6, and then the extension length of the electric telescopic rod 3 is controlled by an external control structure. The electric telescopic rod 3 pushes the clamping block 8 to move, so that the silicone pad 7 fits against the mold body 6. The silicone pad 7 provides cushioning and prevents the clamping block 8 from affecting the mold body 6. The clamping block 8 and the silicone pad 7 reduce the clamping force on the mold. Then, the external vacuum pump is activated, and the main suction... The main suction cup 13 adsorbs the mold body 6, and then air is transmitted through the air pipe 14 and the connector 15. The connector 15 is connected to an external vacuum pump, and the side suction cups 17 adsorb accordingly. This is to accommodate mold bodies 6 of different shapes. However, some side suction cups 17 do not adhere to the mold body 6. Through the external control structure, the corresponding solenoid valve 16 is closed, thus shutting off the side suction cup 17 pipe. Through the coordinated arrangement of the connector 15, air pipe 14, main suction cup 13, solenoid valve 16 and side suction cups 17, the mold body 6 can be adsorbed during use, thereby increasing the fixing effect and reducing the impact of the clamping structure on the lost foam mold.

[0037] When shaping the mold body 6, foam will fall off during the cutting and grinding process. The baffle plate 4 prevents the scattered foam from flying everywhere. The foam adsorbed on the baffle plate 4 can be cleaned into the collection groove 2 and then pushed out for collection. The baffle plate 4 and the collection groove 2 are designed to block and collect the scattered foam. During the shaping process, the high-voltage ionization plate 9 is activated to generate static electricity to attract the fallen foam. The foam will be adsorbed inside the collection plate 10 and supported by the top block 12. The foam will be stored inside the groove 11. After use, the collection plate 10 can be removed and cleaned. Through the coordinated design of the high-voltage ionization plate 9, the collection plate 10, the top block 12 and the groove 11, the scattered foam generated during use can be attracted and collected by static electricity, thus achieving the purpose of convenient foam collection.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
