DETAILED DESCRIPTION

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-3 As shown, a mold release agent dispensing mechanism for perforation includes a support 1 and a plastic dropper bottle. The plastic dropper bottle includes a conical bottle body 2 and a dropper head 3 threadedly connected to the conical bottle body 2. A vertically sliding clamping seat 4 is provided on the support 1. The dropper head 3 of the plastic dropper bottle faces downward. The clamping seat 4 is detachably connected to the threaded interface of the dropper head 3. The clamping seat 4 is an annular clamp. The threaded interface of the dropper head 3 is placed in the clamp, and then the bolt is tightened. If it is necessary to remove the plastic dropper head 3, the bolt is loosened. A conical sleeve 5 is fixed on the support 1 above the clamping seat 4. The conical sleeve 5 is fitted onto the outside of the conical bottle body 2. When the clamping seat 4 moves the plastic dropper bottle downward, the conical sleeve 5 squeezes the conical bottle body 2, causing the mold release agent to drip out.

[0022] Below the dripper 3 is a frame 6, on which a motor-driven conveyor belt 7 is mounted. A limit mechanism is installed on the upper side of the conveyor belt 7, and an infrared proximity switch 9 is fixed to the upper side of the feed end of the limit mechanism. The infrared proximity switch 9 is a reflective infrared proximity switch used to sense passing U-shaped irons. The limit mechanism includes two side baffles 8, which are respectively located on both sides of the upper end of the conveyor belt 7. The side baffles 8 are fixedly connected to the frame 6, and the space between the two side baffles 8 is a limit channel. The spacing of the limit channel allows only one U-shaped iron to pass laterally, facilitating the U-shaped irons to be conveyed one by one in a row. A top baffle 10 is fixed to the upper end of the side baffles 8, and the space between the two top baffles 10 is a drip coating channel. The spacing of the drip coating channel is smaller than the outer diameter of the U-shaped iron, preventing the U-shaped irons from deviating from the conveying path. The perforated parts of the U-shaped irons correspond to the drip coating channels, and the dripper 3 is located above the drip coating channels. The discharge end of the conveyor belt 7 is equipped with a feeding station, which can only accommodate one U-shaped iron. The punching channel and the push rod are located on both sides of the longitudinal direction of the feeding station. When the slide table 11 of the punching machine moves down to punch holes, the U-shaped iron on the conveyor belt 7 moves into the feeding station. When the slide table 11 moves up to reset, the U-shaped iron on the feeding station is sent into the punching channel by the push rod, and the U-shaped iron on the conveyor belt 7 stops being conveyed.

[0023] The support 1 is provided with a direction adjusting wheel 16, a pull rope 17 is slidably arranged on the direction adjusting wheel 16, one end of the pull rope 17 is connected with the clamping seat 4, and the other end is connected with the slide table 11 of the puncher, the slide table 11 vertically slides, and the slide table 11 is fixed with a punching head, and a supporting spring 18 is further arranged between the clamping seat 4 and the upper end of the support 1, that is, when the slide table 11 moves downwards to punch, the clamping seat 4 and the plastic drop bottle are driven to move upwards to reset through the pull rope 17, the supporting spring 18 is compressed, when the slide table 11 moves upwards to reset, the supporting spring 18 is stretched, and the plastic drop bottle is driven to move downwards through the clamping seat 4. In addition, because the slide table 11 moves downwards by a large distance, the inner diameter of the conical sleeve 5 is greater than the outer diameter of the opening of the conical bottle body and is smaller than the outer diameter of the closed end of the conical bottle body, and the conical sleeve 5 can extrude the conical bottle body only after the plastic drop bottle moves downwards by a certain distance, so that the release agent is prevented from being squeezed out when the plastic drop bottle is just moved downwards, and the release agent is prevented from being squeezed out in a large amount. Through the drop coating of the release agent, the separation of the U-shaped iron and the punching head after punching is more favorable.

[0024] When the slide table 11 moves upwards, the supporting spring 18 is stretched, the clamping seat 4 and the plastic drop bottle are driven to move downwards, the conical sleeve 5 extrudes the conical bottle body 2 of the plastic drop bottle, and the release agent is dropped at the punching position of the U-shaped iron; when the slide table 11 moves downwards, the clamping seat 4 and the plastic drop bottle are driven to move upwards to reset through the pull rope 17, and the supporting spring 18 is compressed.

[0025] Embodiment 2

[0026] The embodiment is basically the same as the embodiment 1, and the difference lies in that, as shown in Figs. Figure 1 and 4 A sealing mechanism cooperating with the drop head 3 is arranged on the support 1 below the clamping seat 4, the sealing mechanism comprises a horizontal plate 12 fixed on the support 1, the horizontal plate 12 is located directly above the drop coating channel, the horizontal plate 12 is provided with a through hole 13 cooperating with the drop head 3, the inner diameter of the through hole 13 is relatively large, and the downward movement of the drop head 3 is not affected, the lower end of the through hole 13 is provided with a sealing piece 14, one end of the sealing piece 14 is a free end, and the other end is hinged to the horizontal plate 12 through a rotating shaft 15, a torsional spring is arranged on the rotating shaft 15, the upper end of the drop head 3 abuts against the sealing piece 14, and the drop head 3 moves downwards to push away the sealing piece 14. When the plastic drop bottle moves downwards, the sealing piece 14 is pushed to rotate downwards, and the drop head 3 passes through the through hole 13; after the plastic drop bottle moves upwards, the sealing piece 14 is reset under the action of the torsional spring to seal the outlet of the drop head 3, so that the plastic drop bottle is prevented from leaking.
