Description

Technical Field

[0001] This utility model belongs to the field of terminal processing, and specifically relates to a flipping ejection tool. Background Technology

[0002] A terminal is a connecting element in electronic and electrical components, used to connect a conductor to a receiving terminal in a device or cable. The terminal housing is a protective shell used to protect the terminal and its internal connections from external environmental influences, and is generally made of plastic.

[0003] Terminal housing manufacturing often uses die stamping support. After stamping, the workpiece needs to be ejected from the die. Existing ejection tooling structures are fixed, and the support is used for the die corresponding to the demolding hole. This has low applicability and makes it inconvenient to change the die.

[0004] Therefore, we propose a flipping ejection fixture. Utility Model Content

The ejection assembly passes through the base. A hydraulic mechanism is detachably connected to the top of the top plate. A punch is detachably installed below the top plate. The punch corresponds to the die.

[0007] Preferably, positioning grooves are provided above the base and below the top plate, and the punch and die are respectively engaged with the corresponding positioning grooves.

[0009] Preferably, a pull plate is fixedly installed on the outside of the pin, and a spring is fixedly installed on the inside of the pull plate. There are two springs, and the two springs are arranged symmetrically.

[0010] Preferably, a flange is fixedly installed on the top of the top plate, the flange is arranged in the middle of the top plate, and a threaded hole is opened above the flange. There are multiple threaded holes arranged in an array.

[0011] Preferably, the buffer assembly includes a slide plate, the base has a cavity, the slide plate is slidably installed in the cavity, the top of the slide plate is fixedly installed with buffer columns, there are four buffer columns, the four buffer columns are arranged at the four corners of the slide plate, and the buffer columns penetrate the base and are slidably connected to the base, the bottom of the slide plate is fixedly installed with springs, there are multiple springs, and the multiple springs are arranged at equal intervals.

[0012] Preferably, there are multiple ejector components, which are fixedly installed on the top of the slide plate and are evenly distributed.

[0014] This invention has the following advantages over the prior art:

[0015] 1. The present invention provides a flip-out ejection fixture. During installation, the pull plates on both sides of the base and the top plate are pulled, and the pull plates drive the pin to slide in the socket, thereby disengaging from the positioning groove. At this time, the spring is in a compressed state. The punch and die are inserted into the positioning grooves on the base and the top plate respectively. The pull plates are released, and the pull plates push the pin to slide in the socket under the action of the spring, thereby making the pin engage with the positioning hole. The installation is simple and the fixation is strong.

[0016] 2. The present invention provides a flipping ejection fixture in which the raw material is placed above the die cavity. The ejector plate is pushed by the hydraulic mechanism, and the ejector plate pushes the punch downward. During the downward movement of the ejector plate, the buffer column is pushed to slide, and the buffer column pushes the slide plate to slide. The slide plate compresses the second spring, thereby driving the ejection assembly to move into the cavity. At this time, the punch and die cavity are closed, thereby completing the shaping. The hydraulic mechanism is then activated in reverse, and the second spring pushes the slide plate upward, thereby driving the ejection assembly to eject the workpiece, making demolding more convenient.

[0017] 3. The present invention provides a flipping ejection fixture, which has multiple ejection components and consists of a telescopic structure composed of a sleeve and ejector pins. During demolding, the ejector pins corresponding to the demolding holes of the die are ejected under the action of spring three, while the ejector pins not corresponding to the demolding holes of the die are retracted into the sleeve. It can adapt to different dies and has stronger applicability. Attached Figure Description

[0031] Working principle:

[0032] During installation, pull the pull plates 9 on both sides of the base 1 and the top plate 4. The pull plates 9 drive the pin 7 to slide in the socket, thereby disengaging it from the positioning groove 19. At this time, the spring 8 is in a compressed state. Insert the punch 3 and the die 2 into the positioning grooves 19 on the base 1 and the top plate 4 respectively. Release the pull plates 9. Under the action of the spring 8, the pull plates 9 push the pin 7 to slide in the socket, thereby making the pin 7 engage with the positioning hole 18. The installation is simple and the fixation is strong. Place the raw material above the die 2. Push the top plate 4 through the hydraulic mechanism. The top plate 4 pushes the punch 3 to move down. During the downward movement of the top plate 4, it pushes the buffer column 10 to slide. The buffer column 10 pushes the slide plate 11. Sliding, the slide plate 11 compresses the second spring 12, thereby driving the ejector assembly 13 to move into the cavity. At this time, the punch 3 and the die 2 close, thus completing the shaping. The hydraulic mechanism is activated in reverse, and the second spring 12 pushes the slide plate 11 upward, thereby driving the ejector assembly 13 to eject the workpiece, making demolding more convenient. There are multiple ejector assemblies 13, and the ejector assembly 13 is a telescopic structure composed of a sleeve 14 and ejector pins 17. During demolding, the ejector pins 17 corresponding to the demolding hole of the die 2 are ejected under the action of the third spring 15, while the ejector pins 17 that do not correspond to the demolding hole of the die 2 are retracted into the sleeve 14, which can adapt to different dies 2 and has stronger applicability.
