Description

Technical Field

[0001] This utility model relates to the field of pin insertion equipment, specifically a vertical pin insertion device for irregularly shaped pins in injection molding machines. Background Technology

[0002] Pins are long, thin metal objects used to connect and secure objects. They typically have a pointed head and a flat or rounded bottom. Pins are commonly used to secure fabrics, paper, and other materials, and can also be used to connect electronic components or for decoration. Pins come in various sizes and shapes, such as straight pins, curved pins, and pointed pins.

[0003] Pins typically require a plastic coating, a process performed using an injection molding machine. However, during manufacturing, the pins are placed into a mold, which remains hot after the previous injection molding process. This poses a risk of burns to workers' fingers when inserting the pins, resulting in safety concerns. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a vertical pin insertion device for injection molding machines with irregularly shaped pins, which solves the problem of easy burns during existing pin insertion operations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vertical pin insertion device for an injection molding machine, comprising a pin housing, a fixed shaft mounted inside the pin housing via bearings, a flip seat fixedly connected to the middle section of the fixed shaft, multiple magnetic blocks fixedly connected to the bottom of the flip seat, a pin inserted into the bottom of the pin housing, the pin attracting the magnetic blocks, a driven gear fixedly connected to one end of the fixed shaft located outside the pin housing, two support seats fixedly connected to the upper end of the pin housing, a rotating shaft mounted between the two support seats via bearings, a drive gear fixedly connected to the end of the rotating shaft, and a meshing transmission connection between the drive gear and the driven gear, a partially rotating knob fixedly connected to the middle section of the rotating shaft, the partially rotating knob contacting the pin housing, a bracket fixedly connected to the middle of the upper end of the pin housing, and an anti-accidental contact mechanism provided on the bracket.

[0006] Preferably, a handle is fixedly connected to the top of the pin housing, and the handle is made of plastic. The handle facilitates overall gripping.

[0007] Preferably, a hollow sleeve is fixedly connected to the upper middle part of the pin housing, and a top pin is slidably connected to the inner side of the hollow sleeve. The top pin abuts against the incomplete rotation knob. A spring is provided on the inner side of the hollow sleeve, one end of which is fixedly connected to the top pin, and the other end of which is fixedly connected to the inner surface of the hollow sleeve. The elastic force of the spring can act on the incomplete rotation knob through the top pin.

[0008] Preferably, the anti-accidental touch mechanism includes a limiting rod fixedly connected to the inner side of the bracket, a slider slidably connected to the outer side of the limiting rod, the slider being slidably connected to the bracket, a locking block fixedly connected to the bottom of the slider, the locking block engaging with the incompletely turned knob, and a second spring sleeved on the outer side of the limiting rod. The anti-accidental touch mechanism provides protection against incompletely turned knobs.

[0009] Preferably, a guide block is fixedly connected to the top of the slider, and the guide block is slidably connected to the bracket. The guide block guides the lateral movement of the slider.

[0010] Preferably, one end of the second spring is fixedly connected to the slider, and the other end of the second spring is fixedly connected to the bracket. By using the second spring, the reaction force can be applied to the slider.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model features a hollow shell with a fixed shaft containing a flip seat. The flip seat has a magnetic block. When a pin is inserted into the hollow shell from the bottom, it is fixed by the magnetic block. A driven gear is mounted on the fixed shaft, and a rotatable shaft is mounted on the top of the hollow shell. The shaft has a partial knob and a drive gear. When the pin is inserted into the hollow shell, the shaft is rotated by the partial knob. Through the transmission of the gear, the deflection seat rotates, thereby separating the pin from the magnetic block and completing the pin insertion operation, preventing burns.

[0013] 2. This utility model provides a support on a hollow shell, and an anti-accidental contact mechanism on the support. Under the action of a spring, the locking block at the bottom of the slider engages with the incomplete gear, thereby protecting it and preventing accidental contact that could cause the pin to fall out, thus improving the stability of the pin transfer process.

[0021] Please see Figure 1-4 A vertical pin insertion device for an injection molding machine includes a pin housing 1. A fixed shaft 2 is mounted inside the pin housing 1 via bearings. A flip seat 3 is fixedly connected to the middle section of the fixed shaft 2. Multiple magnetic blocks 4 are fixedly connected to the bottom of the flip seat 3. Pins 16 are inserted into the bottom of the pin housing 1, and the pins 16 are attracted to the magnetic blocks 4. A driven gear 5 is fixedly connected to one end of the fixed shaft 2 located outside the pin housing 1. Two support seats 6 are fixedly connected to the upper end of the pin housing 1. A rotating shaft 7 is mounted between the two support seats 6 via bearings. A drive gear 8 is fixedly connected to the end of the rotating shaft 7, and the drive gear 8 and the driven gear 5 form a meshing transmission connection. A partially rotating knob 9 is fixedly connected to the middle section of the rotating shaft 7, and the partially rotating knob 9 contacts the pin housing 1. A bracket 10 is fixedly connected to the middle of the upper end of the pin housing 1. A handle 11, made of plastic, is fixedly connected to the top of the pin housing 1. The handle 11 facilitates overall gripping.

[0022] Please see Figure 4-5A hollow sleeve 13 is fixedly connected to the upper middle part of the pin housing 1. A top pin 14 is slidably connected to the inner side of the hollow sleeve 13. The top pin 14 abuts against the incomplete knob 9. A spring 15 is provided on the inner side of the hollow sleeve 13. One end of the spring 15 is fixedly connected to the top pin 14, and the other end of the spring 15 is fixedly connected to the inner surface of the hollow sleeve 13. The elastic force of the spring 15 can act on the incomplete knob 9 through the top pin 14.

[0023] Please see Figure 1-4 The bracket 10 is equipped with an anti-accidental touch mechanism 12, which protects against incomplete rotation of the knob 9. The anti-accidental touch mechanism 12 includes a limiting rod 121 fixedly connected to the inner side of the bracket 10, a slider 122 slidably connected to the outer side of the limiting rod 121, and a locking block 123 fixedly connected to the bottom of the slider 122, which engages with the incomplete rotation of the knob 9. A second spring 125 is sleeved on the outer side of the limiting rod 121, with one end fixedly connected to the slider 122 and the other end fixedly connected to the bracket 10. The spring 125 allows a reaction force to be applied to the slider 122. A guide block 124 is fixedly connected to the top of the slider 122, and slidably connected to the bracket 10. The guide block 124 guides the lateral movement of the slider 122.

[0024] The specific implementation process of this utility model is as follows: In use, firstly, insert the disc pin 16 from the bottom of the pin housing 1 and attract it with the magnetic block 4 on the flipping seat 3. Then, the operator holds the handle 11 to transfer the whole and transfer the pin 16 into the mold, and insert the end into the reserved position in the mold. Then, pull the slider 122 horizontally to separate the locking block 123 at the bottom of the slider 122 from the incomplete knob 9. Then, rotate the incomplete knob 9. The incomplete knob 9 drives the drive gear 8 to rotate through the rotating shaft 7. The drive gear 8, through the transmission with the driven gear 5, causes the fixed shaft 2 and the flipping seat 3 to rotate, thereby causing the magnetic block 4 to disengage from the pin 16, and the pin 16 to flow smoothly into the mold to complete the pin insertion operation and prevent burns.
