TECHNICAL FIELD
[0001] The present application belongs to the field of automobile machinery, and particularly relates to a repairing device for internal parts of a compression mold. BACKGROUND
[0002] At present, all internal parts of a mold are designed in a compression plate, and when debugging on a press, the internal parts cannot be repaired because they are in the compression plate, and the mold needs to be taken off line, and the upper mold compression plate is disassembled to repair the internal parts, which is time-consuming and labor-consuming and cannot meet the needs of repairing the internal parts when debugging on the press. SUMMARY
[0003] To solve the above problems, the present application discloses a repairing device for internal parts of a compression mold, which solves the problem that the internal parts in the compression plate cannot be repaired when the mold is debugged on the press, saves time and labor, improves the mold repairing efficiency, and the repairing precision is also improved.
[0004] A repairing device for internal parts of a compression mold, comprising a die, a compression plate, internal parts, a punch, a side pin baffle, a side pin, a first side pin hole and a second side pin hole; the compression plate is slidingly arranged in the die; wherein the internal parts are located in the compression plate; the side edge of the die is provided with a side pin baffle; wherein the compression plate is sequentially provided with a first side pin hole and a second side pin hole; the punch is used to push against the compression plate; wherein one end of the side pin is provided with a clamping groove, and the other end penetrates through the die and is located in the first side pin hole; the lower end of the first side pin hole is communicated with the second side pin hole.
[0005] Further, the lower end of the side pin baffle is matched with the clamping groove.
[0006] Further, a nitrogen spring is arranged above the compression plate; wherein the nitrogen spring is arranged in the die, so as to stabilize the movement and return of the compression plate.
[0007] Further, the second side pin hole is located beside the internal parts.
[0008] When the present application works:
[0009] The mold is installed on the press, the press is controlled to be pressed down, the punch pushes against the compression plate, and the compression plate is compressed downward, when the compression plate reaches the lower dead point position of the mold, the side pin is in the same position as the second side pin hole at this time; the baffle fixing bolt is removed, the side pin baffle is removed, the side pin is advanced and inserted into the second side pin hole, and the side pin baffle and the baffle fixing bolt are installed; at this time, the compression plate is locked by the side pin and cannot return. The press is controlled to return to the initial position, and the internal parts in the compression plate are exposed at this time, and the repairing operation can be performed without disassembly, and the repairing precision can be guaranteed.
[0010] The beneficial effects of this utility model are: it improves the efficiency of mold repair and also enhances the precision of the repaired mold. Attached Figure Description

[0014] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0015] like Figure 1 As shown, a repair device for internal components of a pressing die according to this embodiment includes a die cavity 1, a pressing plate 2, internal components 3, a punch 4, a side pin baffle 5, a side pin 7, a primary side pin hole 8, and a secondary side pin hole 9; the pressing plate 2 is slidably disposed inside the die cavity 1; wherein the internal components 3 are located inside the pressing plate 2;
[0016] A nitrogen spring 10 is provided above the pressure plate 2; the nitrogen spring 10 is located inside the die cavity 1. When the pressure plate 2 moves downward, it applies pressure to ensure the processing quality of the part; when the pressure plate 2 is completed and moves upward, the nitrogen spring 10 plays a pressure-holding role and slowly reduces the pressure.
[0017] The die 1 has a side pin baffle 5 on its side; wherein the pressure plate 2 has a first-level side pin hole 8 and a second-level side pin hole 9 in sequence; wherein the second-level side pin hole 9 is located next to the internal component 3.
[0018] The punch 4 is used to hold the pressure plate 2; one end of the side pin 7 is provided with a groove 71 and the other end passes through the die 1 and is located in the first-stage side pin hole 8; the lower end of the side pin baffle 5 is fitted with the groove 71; the lower end of the first-stage side pin hole 8 communicates with the second-stage side pin hole 9.
[0019] The embodiment installs the mold on the press, controls the press to press down, the male die 4 stops the pressing plate 2, and makes it compress downward, when it reaches the lower dead point position of the mold, at this time, the side pin 7 is in the same position with the secondary side pin hole 9. The baffle fixing bolt 6 is removed, the side pin baffle 5 is removed, the side pin 7 is inserted into the secondary side pin hole 9, and the side pin baffle 5 and the baffle fixing bolt 6 are installed. At this time, the pressing plate 2 is locked by the side pin 7 and cannot be reset. Control the press to return to the initial position, at this time, the internal parts in the pressing plate 2 will be exposed, the repair work can be carried out in the state of not being disassembled, and the repair precision can be guaranteed.
