Description

Technical Field

[0001] This utility model belongs to the field of mold cavity cleaning waste chip technology, and in particular relates to an air blowing chip cleaning device for mold cavities. Background Technology

[0002] During the mold processing of parts, due to the physical properties of the parts materials and the friction between the mold structure and the parts during mold closing, waste particles generated during processing can easily accumulate in the die cavity, affecting the quality and safety of mold processing. Generally, companies use air guns or cleaning brushes to remove waste particles regularly. However, the process of removing waste particles will occupy the space between the punch and the die cavity. Therefore, the mold needs to be stopped during each chip removal operation. The chip removal operation interferes with the mold processing operation and affects the mold processing efficiency. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides an air blowing chip removal device for a mold cavity. By sliding an air blowing pipe on the mold cavity, the air blowing pipe can be fed into the cavity to perform air blowing chip removal without occupying the space between the punch and the cavity, ensuring that chip removal and mold processing do not interfere with each other.

[0004] Technical Solution: To achieve the above objectives, this utility model provides an air-blowing chip removal device for a mold cavity, comprising a punch and a cavity that fit together. The air-blowing chip removal device is mounted on the cavity and includes an air-blowing pipe. The tail end of the air-blowing pipe is an air inlet, and the front end is a closed structure with an air outlet near the pipe wall of the closed structure. The cavity has a transversely extending slide rail near its inner bottom, and the air-blowing pipe slides into the slide rail. When the air-blowing pipe slides forward to fill the slide rail, the closed structure is aligned with the inner wall of the cavity. When the air-blowing pipe slides forward to penetrate the slide rail, the air-blowing pipe is connected to the cavity through the air outlet.

[0005] Furthermore, when the punch is lowered and the die is closed, the closed structure constitutes a structural part of the inner wall of the die.

[0006] When the punch moves upward and the die is in the open state, the air blower blows air into the die through the air outlet.

[0007] Furthermore, the air outlet is located at the bottom of the air blowing pipe so that the air blowing direction of the air outlet is towards the inner bottom surface of the die.

[0008] Furthermore, the air outlet has a gradually narrowing structure from the air inlet end to the air outlet end.

[0009] Furthermore, it includes an air supply source, and the air inlet of the air blowing pipe is connected to an air supply pipe led out from the air supply source via a connector.

[0010] Furthermore, it includes a feed drive mechanism corresponding to the air blow pipe, which is mounted on the side of the die cavity via the feed drive mechanism, and the air blow pipe is driven by the feed drive mechanism to slide within the slide.

[0011] Beneficial effects: This utility model features an air blowing pipe that slides onto the concave mold of a mold. The air blowing pipe can be fed into the concave mold without occupying the space between the punch and the concave mold to perform air blowing chip removal. Specifically, the air blowing pipe retracts into the slideway when the mold is closed, allowing the closed structure to fill the slideway and become part of the inner wall structure of the concave mold. When the mold is opened, it slides out of the slideway and extends into the concave mold, using the air outlet to remove waste chips from the concave mold. This ensures that the chip removal operation and the mold processing operation do not interfere with each other, allowing both operations to proceed normally and improving efficiency.

[0014] Figure 3 Schematic diagram of an air-blowing chip removal device used for chip removal in mold dies. Figure 2 . Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figure 1 and Figure 2 As shown, a blow-blowing chip removal device for a mold cavity includes a punch 1 and a cavity 2 that fit together. A blow-blowing chip removal device 3 is disposed on the cavity 2. The blow-blowing chip removal device 3 includes an air blowing pipe 4, the tail end of which is an air inlet, and the front end is a closed structure 40. An air outlet 41 is provided on the pipe wall near the closed structure 40. A slide rail 20 is laterally formed through the cavity 2 near its inner bottom, and the blow-blowing pipe 4 slides in conjunction with the slide rail 20. Figure 2 As shown, when the air blowing pipe 4 slides and feeds to fill the slide 20, the closed structure 40 is aligned with the inner wall of the die 2; more specifically, when the punch 1 moves down and the die 2 is closed, the closed structure 40 constitutes a structural part of the inner wall of the die 2. Figure 3As shown, when the air blow pipe 4 is slidably fed into the through slide 20, the air blow pipe 4 is connected to the die 2 through the air outlet 41. More specifically, when the punch 1 is moved upward and the die 2 is in the open state, the air blow pipe 4 blows air into the die 2 through the air outlet 41. This utility model, by sliding the air blow pipe 4 on the die 2, allows the air blow pipe 4 to be fed into the die for air blowing chip removal without occupying the space between the punch and the die. That is, when the die is closed, the air blow pipe 4 retracts into the slide 20, so that the closed structure 40 fills the slide 20 and becomes part of the inner wall structure of the die 2. When the die is opened, it slides out of the slide 20 and extends into the die 2, using the air outlet 41 to remove waste chips from the die. This ensures that the chip removal operation and the die processing operation do not interfere with each other, and both operations can be carried out normally, which helps to improve efficiency.

[0017] In order to make the cleaning more thorough, in this utility model, the air outlet 41 is located at the bottom of the air blowing pipe 4, so that the blowing direction of the air outlet 41 is towards the inner bottom surface of the die 2. After the gas is blown towards the inner bottom surface of the die 2, it rises in the opposite direction and is discharged from the top opening of the die 2.

[0018] When gas is blown out from the vent 41, the blowing force directly affects the chip removal effect. In order to improve the blowing force, in this application, the vent 41 has a gradually contracting structure from the air inlet end to the air outlet end, so that the force when the gas is blown out from the vent 41 is greater and the waste chips in the die 2 are removed more effectively.

[0019] like Figure 1 and Figure 2 As shown, this utility model includes an air supply source 5. The air inlet of the air blowing pipe 4 is connected to an air supply pipe 7 led out from the air supply source 5 via a connector 6. The air supply source 5 can be an air pump. The connector 6 is a straight-through connecting pipe structure, wherein: the middle is a hexagonal structure for easy installation with a wrench; a sealing ring 9 is squeezed between the hexagonal structure and the air blowing pipe 4; the end connected to the air inlet of the air blowing pipe 4 is a threaded pipe section structure; and the end connected to the air supply pipe 7 is a straight pipe section. The air supply pipe 7 is fitted onto the straight pipe section and then secured with a clamp 10.

[0020] like Figure 1 and Figure 2As shown, this utility model includes a feed drive mechanism 8 corresponding to the air blow pipe 4. The air blow pipe 4 is mounted on the side of the die 2 via the feed drive mechanism 8, and the air blow pipe 4 is driven by the feed drive mechanism 8 to slide within the slide rail 20. The feed drive mechanism 8 includes a bracket 11, a feed cylinder 12, a connecting plate 13, a guide rod 14, and a guide sleeve 15. The bracket 11 is mounted on the side of the die 2. The feed cylinder 12 is mounted on the bracket 11 in a transverse position. The connecting plate 13 is connected to the piston rod of the feed cylinder 12. The air blow pipe 4 has a fixedly connected mounting plate 42 on its exterior. The connecting plate 13 has a pre-drilled hole for the air blow pipe 4 to pass through. The mounting plate 42 is fastened to the connecting plate 13 by hexagonal screws. The guide rod 14 is mounted transversely on the side of the die 2 via a threaded connection. The guide sleeve 15 is embedded in the connecting plate 13, and the guide rod 14 passes through the guide sleeve 15.

[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
