Description

Technical Field

[0001] This invention relates to the field of air compressor parts processing, and particularly to a mold for processing air compressor parts. Background Technology

[0002] An air compressor is a device used to compress gases. Air compressors are similar in construction to water pumps. Most air compressors are reciprocating piston, rotary vane, or rotary screw types. During air compressor production, many parts (such as end caps) require hydraulic forming using molds. However, existing molds can easily cause the formed parts to get stuck in the mold cavity, making them difficult to remove.

[0003] Therefore, a precision mold for easily removing special parts for air compressors was developed, such as the one with patent number CN217990741U. Although this device can solve the above problems, it has the following defects: the product is stuck after it is tightly attached to the inner wall of the mold cavity, making it difficult to push the push rod and push block upward by the spring extension force, thus affecting the demolding work. Summary of the Invention

[0004] The purpose of this invention is to provide a mold for processing air compressor parts.

[0005] The technical problem of this invention is mainly solved by the following technical solution:

[0006] A mold for processing air compressor parts includes a housing, an annular seat fixed to the top of the housing, a circular seat disposed inside the annular seat, a mold cavity disposed at the top of the circular seat, a circular hole for accommodating a circular plate disposed at the bottom center of the mold cavity, a screw extending into the housing disposed on the circular plate, a threaded tube movably disposed on the top wall of the housing and screwed to the screw, the threaded tube being connected to a rotating shaft on a motor via a transmission belt, a gear disposed at the top of the rotating shaft, a groove for accommodating the gear being disposed around the inner side wall of the annular seat, and a toothed ring meshing with the gear being sleeved on the circular seat;

[0007] It also includes a top plate located above the circular base and driven by a hydraulic rod, with an upper mold base corresponding to the mold cavity at the bottom of the top plate, and a demolding mechanism provided on the upper mold base.

[0008] Preferably, an arc-shaped groove is provided on the inner wall of the annular seat and the outer wall of the circular seat above the groove, wherein the two sets of arc-shaped grooves form a sliding channel with a circular cross-section, and a number of balls are uniformly arranged in the sliding channel.

[0009] Preferably, a bearing for fixing the top end of the helical tube is provided on the top wall of the housing, and pulleys for fixing the transmission belt are respectively provided on the helical tube and the rotating shaft, and the motor is located at the bottom of the housing.

[0010] Preferably, the circular plate is suspended at the top of the circular hole, and the top of the circular plate is flush with the bottom wall of the mold cavity. The screw is fixedly connected to the middle of the bottom plate of the circular plate. The screw passes through the hole on the top wall of the box. The bottom end of the screw is provided with a bottom plate located below the screw tube. The bottom plate is connected to the bottom wall of the box through multiple sets of telescopic rods.

[0011] Preferably, a cooling groove is arranged around the bottom surface of the circular seat, located outside the mold cavity. An air inlet pipe and an air outlet pipe communicating with the cooling groove are respectively arranged on both sides of the top wall of the box body. The air inlet pipe is connected to an exhaust fan through a pipe.

[0012] Preferably, the demolding mechanism includes a receiving groove located in the middle of the bottom of the upper mold base, a boss is provided in the receiving groove, the bottom of the boss is flush with the bottom of the upper mold base, a T-shaped rod is provided above the top plate with its bottom end connected to the top of the boss, a sliding channel through hole is provided on the top plate and the upper mold base for the T-shaped rod to pass through, and a spring is sleeved on the T-shaped rod above the top plate.

[0013] The beneficial effects of this invention are as follows: This invention drives the mold cavity to rotate by mechanically driving the circular seat to rotate, so that the mold cavity is separated from the outer wall of the product. At the same time, it also drives the screw to move upward by mechanically driving the screw tube, so that the circular plate slides upward from the circular hole, pushing the product to slide upward from the mold cavity to achieve demolding. When the product is lifted by the upper mold seat, the demolding mechanism can be pressed down to smoothly remove the product from the upper mold seat. Attached Figure Description

[0017] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0018] A mold for processing air compressor parts includes a housing 1. An annular seat 2 is fixed to the top of the housing 1. A circular seat 3 is provided inside the annular seat 2. A mold cavity 4 is provided at the top of the circular seat 3. A circular hole 5 for accommodating a circular plate 6 is provided at the middle of the bottom of the mold cavity 4. A screw 7 extending into the housing 1 is provided on the circular plate 6. A screw tube 8 connected to the screw 7 is movably provided on the top wall of the housing 1. The screw tube 8 is connected to the rotating shaft 11 on the motor 10 through a transmission belt 9. A gear 12 is provided at the top of the rotating shaft 11. A groove 13 for accommodating the gear 12 is provided around the inner side wall of the annular seat 2. A toothed ring 14 that meshes with the gear 12 is sleeved on the circular seat 3.

[0019] It also includes a top plate 15 located above the circular base 3 and driven by a hydraulic rod 16. The bottom of the top plate 15 is provided with an upper mold base 17 corresponding to the mold cavity 4. The upper mold base 17 is provided with a demolding mechanism 18. The demolding mechanism 18 includes a receiving groove located in the middle of the bottom of the upper mold base 17. A boss 181 is provided in the receiving groove. The bottom of the boss 181 is flush with the bottom of the upper mold base 17. A T-shaped rod 182 is provided above the top plate 15, with its bottom end connected to the top of the boss 181. The top plate 15 and the upper mold base 17 are provided with sliding channel through holes for the T-shaped rod 182 to pass through. A spring 183 is sleeved on the T-shaped rod 182 above the top plate 15.

[0020] like Figure 2 As shown, an arc-shaped groove 19 is correspondingly provided on the inner wall of the annular seat 2 and the outer wall of the circular seat 3 above the groove 13. The two sets of arc-shaped grooves 19 form a sliding channel with a circular cross-section. A plurality of balls 20 are evenly arranged in the sliding channel. By the balls 20 hooking onto the side wall of the arc-shaped groove 19, the circular seat 3 is prevented from moving up and down within the annular seat 2. At the same time, when the circular seat 3 rotates, it also drives the side wall of the arc-shaped groove 19 to slide on the balls 20, thereby reducing the resistance to its rotation.

[0021] like Figure 2 As shown, a bearing 21 is provided on the top wall of the inner box 1 to fix the top end of the screw tube 8. The screw tube 8 is fixed by the bearing 21, and it is also convenient for the screw tube 8 to rotate on the top wall of the inner box 1 through the bearing 21. The screw tube 8 and the rotating shaft 11 are respectively provided with pulleys for fixing the transmission belt 9. The motor 10 is located at the bottom of the inner box 1.

[0022] In this embodiment, the circular plate 6 is suspended at the top of the circular hole 5. The top of the circular plate 6 is flush with the bottom wall of the mold cavity 4. The screw 7 is fixedly connected to the middle of the bottom plate of the circular plate 6. The screw 7 passes through the hole on the top wall of the box 1. The bottom end of the screw 7 is provided with a bottom plate 22 located below the screw tube 8. The bottom plate 22 is connected to the bottom wall of the box 1 through multiple sets of telescopic rods 23.

[0023] like Figure 2 As shown, a cooling groove 24 is arranged around the bottom surface of the circular seat 3, located outside the mold cavity 4. An air inlet pipe 25 and an air outlet pipe 26 communicating with the cooling groove 24 are respectively arranged on both sides of the inner top wall of the box body 1. The air inlet pipe 25 is connected to the exhaust fan through a pipe.

[0024] In operation, the hydraulic rod 16 drives the top plate 15 to move the upper mold base 17 to extrude and form the product inside the mold cavity 4. When the product needs to be removed after extrusion, the upper mold base 17 fixes the product inside the mold cavity 4. At the same time, the motor 10 drives the gear 12 to rotate through the rotating shaft 11, which in turn drives the gear ring 14 to rotate. This causes the gear ring 14 to drive the circular seat 3 to rotate within the opening of the annular seat 2, thereby separating the side wall of the mold cavity 4 from the outer wall of the product. At this time, the rotating shaft 11 drives the solenoid 8 to rotate on the bearing 21 through the transmission belt 9. As screw 8 rotates, it drives screw 7 to move downward. At this time, the base plate 22 is fixed by telescopic rod 23, which indirectly prevents screw 7 and screw tube 8 from rotating together. When screw 7 moves up and down, it drives telescopic rod 23 to contract or expand through base plate 22. During the above process, when screw 7 moves down, it drives circular plate 6 to slide downward in circular hole 5, so that it separates from the bottom end face of product in mold cavity 4 and does not press upward on the bottom end face of product. Thus, circular plate 6 does not affect the rotation of circular seat 3 so that the side wall of mold cavity 4 can be smoothly separated from product.

[0025] In the above process, the cold air is introduced into the air inlet pipe 25 by the exhaust fan, then flows into the cooling tank 24, and finally enters the box 1 through the air outlet pipe 26. At the same time, it is discharged from the exhaust port on the side wall of the box 1. By introducing the cold air into the cooling tank 24 for cooling, the mold cavity 4 is indirectly cooled and cooled down, preventing the high temperature generated when the side wall of the mold cavity 4 separates from the product, which would affect its quality.

[0026] Next, the upper mold base 17 moves upward and resets. If the product is lifted by the upper mold base 17, the protrusion 181 can be pushed out of the receiving groove by pressing the T-shaped rod 182 and compressing the spring 183. This causes the protrusion 181 to push the product on the upper mold base 17 to fall off. At the same time, when the pressing pressure is removed, the spring 183 extends and pushes the T-shaped rod 182 and drives the protrusion 181 to slide into the receiving groove.

[0027] When the upper mold base 17 is reset, and the product is still in the mold cavity 4, the motor 10 reverses. It drives the screw tube 8 to reverse through the rotating shaft 11 and the transmission belt 9, which in turn drives the screw 7 to move upward and pushes the circular plate 6 to slide out of the circular hole 5 into the mold cavity 4, thereby ejecting the product from the mold cavity 4 and realizing the demolding of the product.

[0028] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
