DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4 A mold for processing a car handbrake mounting bracket comprises an upper mold 1 and a lower mold 2, wherein the upper mold 1 and the lower mold 2 are connected by a connecting assembly, a mold groove 3 is provided on the lower mold 2, the connecting assembly comprises two connecting blocks 9 symmetrically fixedly installed on the lower mold 2 and two fastening bolts 10, a first connecting hole is symmetrically provided on the upper mold 1, a second connecting hole is provided on each of the two connecting blocks 9, and the fastening bolts 10 are installed in the first connecting hole and the second connecting hole;

[0023] Before pouring, cover the upper mold 1 on the lower mold 2, align the first connecting hole on the upper mold 1 with the second connecting hole on the connecting block 9, and then insert the fastening bolts 10 into the first connecting hole and the second connecting hole, and connect the upper mold 1 and the lower mold 2 together through the fastening bolts 10.

[0024] A U-shaped mounting hole 4 is provided on the lower mold 2, a U-shaped block 5 is vertically slidably installed in the mounting hole 4, a movable hole connected to the mounting hole 4 is provided on the bottom wall of the mold groove 3, a top plate 6 is vertically slidably installed in the mold groove 3, and movable rods 7 are vertically slidably installed in the two movable holes, and the upper and lower ends of the two movable rods 7 are respectively fixedly connected to the top plate 6 and the U-shaped block 5, and two spring rods 8 are fixedly installed on the lower surface of the U-shaped block 5, and the lower ends of the two spring rods 8 are fixedly connected to the bottom wall of the mounting hole 4.

[0025] When the upper die 1 is mounted on the lower die 2, the lower surface of the upper die 1 will contact the two ends of the U-shaped block 5, and drive the U-shaped block 5 to move vertically downward in the mounting hole 4, the two spring rods 8 are compressed, and at the same time, the U-shaped block 5 will drive the top plate 6 to move vertically downward through the moving rod 7. When the upper die 1 and the lower die 2 are closed, the top plate 6 also moves to the lowest end of the die groove 3.

[0026] After the mounting bracket is cooled and formed, the lock between the upper mold 1 and the lower mold 2 is unlocked, and then the upper mold 1 is removed from the lower mold 2. At this time, under the action of the elastic force of the two spring rods 8, the U-shaped block 5 will be driven to move vertically upward, and the U-shaped block 5 will then drive the top plate 6 to move vertically upward in the mold groove 3 through the moving rod 7. When the top plate 6 moves, it will push the formed mounting bracket to move, so that it moves relative to the inner wall of the mold groove 3, thereby detaching from the mold groove 3. Finally, the formed mounting bracket is ejected from the mold groove 3 by the top plate 6 to complete the demoulding. The operation is simple, time-saving and labor-saving, and the production efficiency is effectively improved.

[0027] The lower surface of the upper mold 1 is symmetrically provided with positioning grooves, and the two ends of the U-shaped block 5 are respectively inserted into the two positioning grooves. When the upper mold 1 is covered on the lower mold 2, the two ends of the U-shaped block 5 are respectively inserted into the two positioning grooves. The upper mold 1 is quickly positioned through the two positioning grooves, so that the first connecting hole on the upper mold 1 and the second connecting hole on the connecting block 9 are quickly aligned.

[0028] A circular sealing strip 11 is fixedly mounted on the top plate 6, and the sealing strip 11 is in sliding contact with the inner wall of the mold groove 3. The sealing strip 11 can reduce the gap between the top plate 6 and the mold groove 3 to prevent the raw material from entering the gap between the top plate 6 and the mold groove 3 during pouring.

[0029] The lower die 2 is symmetrically provided with mounting grooves, and a U-shaped frame 12 is fixedly installed on both the front and rear surfaces of the lower die 2. A sliding hole is provided on the U-shaped frame 12, and a sliding rod 13 is slidably inserted in the sliding hole. A striking block 14 is fixedly installed on one end of the sliding rod 13, and a telescopic spring 15 is sleeved on the sliding rod 13. The two ends of the telescopic spring 15 are respectively fixedly connected to the striking block 14 and the U-shaped frame 12. A pull rod 16 is fixedly installed on the end of the sliding rod 13 away from the striking block 14, and an anti-slip belt is wrapped around the pull rod 16.

[0030] After pouring, the pull rod 16 can be pulled to drive the impact block 14 away from the lower mold 2 through the slide rod 13, and the telescopic spring 15 is compressed. Then, the pull rod 16 is released. Under the action of the elastic force of the telescopic spring 15, the impact block 14 will quickly hit the lower mold 2, driving the lower mold 2 to vibrate. Under the vibration, the bubbles in the raw material of the mold groove 3 will float up, thereby removing the bubbles generated in the mold groove 3, making the surface of the mounting bracket smoother after molding;

[0031] At the same time, after the mounting bracket is cooled and formed, the pull rod 16 can be pulled to drive the impact block 14 to impact the lower mold 2. Under the vibration, the mounting bracket can be easily separated from the inner wall of the mold groove 3, making it more convenient to demould.

[0032] In the utility model, after the mounting bracket is cooled and formed, the upper mold 1 is removed from the lower mold 2. Under the action of the elastic force of the spring rod 8, the U-shaped block 5 will drive the top plate 6 to move vertically upward in the mold groove 3 through the moving rod 7. When the top plate 6 moves, it will push the formed mounting bracket to move, so that it moves relative to the inner wall of the mold groove 3, thereby detaching from the mold groove 3. Finally, the formed mounting bracket is ejected from the mold groove 3 by the top plate 6 to complete the demoulding. The operation is simple, time-saving and labor-saving, and the production efficiency is effectively improved.

[0033] In general, in view of the technical problem that it is very troublesome, time-consuming and labor-intensive to remove the mounting bracket from the die groove 3, which greatly reduces the production efficiency; a technical solution is adopted: the spring rod 8, U-shaped block 5, moving rod 7 and top plate 6 cooperate with each other to separate the mounting bracket from the inner wall of the die groove 3; because the implementation process of the technical solution is: after the mounting bracket is cooled and formed, the upper mold 1 is removed from the lower mold 2, and under the action of the elastic force of the spring rod 8, the U-shaped block 5 will drive the top plate 6 to move vertically upward in the die groove 3 through the moving rod 7, and when the top plate 6 moves, it will push the formed mounting bracket to move, so that it moves relative to the inner wall of the die groove 3, thereby detaching from the die groove 3, and finally the formed mounting bracket is ejected from the die groove 3 through the top plate 6 to complete the demoulding; so the technical problem can be solved inevitably, and the technical effect achieved is: simple operation, time-saving and labor-saving, and effective improvement of production efficiency.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
