Description

Technical Field

[0001] The utility model generally relates to the field of injection molding tools, and in particular to a nozzle pliers. Background Art

[0002] The sprue is the hole reserved in the injection mold for pouring the raw material into the mold. After the workpiece is injection molded, the part on the molded part that connects to the hole is called the sprue. After the injection molded part is formed, the sprue material needs to be removed. To address the problems of cosmetic damage to the molded part caused by irregular manual tooling during sprue removal, structural damage can lead to a decrease in aging resistance, and inadequate fixation of the molded part can cause overall deformation and increased warpage. Therefore, sprue pliers are currently used to cut the sprue material.

[0003] A Chinese patent with publication number CN217494336U discloses a nozzle pliers with a recycling function. When the first and second pliers handles are clamped and the first and second cutters are used to cut the gate material of the injection molded part, due to the lack of a limiting structure, the first and second cutters will collide, resulting in bite damage to the first and second cutters, which affects the service life of the nozzle pliers. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a nozzle pliers with a long service life.

[0005] In a first aspect, the nozzle pliers of the present invention include:

[0021] Please refer to Figures 1 to 5The nozzle pliers of the present invention include: a pivot 100; a first handle 200, which pivots around the pivot 100; a second handle 400, which pivots around the pivot 100; a first pliers head 300, which is connected to the first handle 200, the first pliers head 300 includes a first shearing blade 310 and a first fixing seat 320, the first shearing blade 310 is fixedly connected to the first fixing seat 320, the first fixing seat 320 is provided with a first groove 321 and a first limit block 322, the first groove 321 passes through the first fixing seat 320 along the thickness direction of the first fixing seat 320, and the first groove 321 is located between the first shearing blade 310 and the first limit block 322; the second pliers head 50 0, which is connected to the second handle 400, the second pliers 500 includes a second shearing edge 510 and a second fixed seat 520, the second shearing edge 510 is fixedly connected to the second fixed seat 520, the second fixed seat 520 is provided with a second groove 521 and a second limit block 522, the second groove 521 passes through the second fixed seat 520 along the thickness direction of the second fixed seat 520, and the second groove 521 is located between the second shearing edge 510 and the second limit block 522; when the first handle 200 and the second handle 400 are pressed and pivoted around the pivot 100, the first shearing edge 310 contacts the second shearing edge 510, and the first limit block 322 contacts the second limit block 522.

[0022] In an embodiment of the present invention, the nozzle pliers include a pivot 100, and a first handle 200 and a second handle 400 are capable of pivoting about the pivot 100, respectively. The first pliers head 300 is connected to the first handle 200, and the second pliers head 500 is connected to the second handle 400. When cutting the sprue material of an injection molded part, the sprue material of the injection molded part is placed between the first shearing blade 310 and the second shearing blade 510, and the first handle 200 and the second handle 400 are pressed together, driving the first shearing blade 310 and the second shearing blade 510 toward each other and cutting the sprue material of the injection molded part. When the first shearing blade 310 and the second shearing blade 510 contact and the sprue material of the injection molded part is cut, the first limit block 322 and the second limit block 522 contact each other, preventing the first shearing blade 310 and the second shearing blade 510 from causing damage due to excessive contact, thereby extending the service life of the nozzle pliers.

[0023] The first rubber sleeve 210 can be sleeved on the first handle 200, and the second rubber sleeve 410 can be sleeved on the second handle 400 to increase the friction when holding the first handle 200 and the second handle 400, making it easier to hold and use the nozzle pliers.

[0024] The first pliers 300 includes a first shearing blade 310 and a first fixing seat 320. The first fixing seat 320 is pivotally connected to the pivot 100, enabling the first handle 200 to pivot about the pivot 100. The thickness of the first fixing seat 320 is greater than that of the first shearing blade 310, ensuring the stability of the pivotal connection between the first fixing seat 320 and the pivot 100. The second pliers 500 includes a second shearing blade 510 and a second fixing seat 520. The second fixing seat 520 is pivotally connected to the pivot 100, enabling the second handle 400 to pivot about the pivot 100. The thickness of the second fixing seat 520 is greater than that of the second shearing blade 510, ensuring the stability of the pivotal connection between the second fixing seat 520 and the pivot 100.

[0025] The first stopper 322 is located on the first fixing seat 320, which supports the first stopper 322 and ensures the strength of the first stopper 322. The second stopper 522 is located on the second fixing seat 520, which supports the second stopper 522 and ensures the strength of the second stopper 522. This ensures that the first stopper 322 and the second stopper 522 can prevent the first and second shearing edges 310 and 510 from interlocking and damaging each other when cutting the gate material of the injection molded part.

[0026] The first groove 321 is located between the first shearing edge 310 and the first stopper 322, and the second groove 521 is located between the second shearing edge 510 and the second stopper 522. The provision of the first groove 321 and the second groove 521 ensures that the first and second shearing edges 310 and 510 can smoothly engage with each other, thereby cutting the gate material of the injection molded part. Furthermore, the provision of the first groove 321 facilitates the processing of the first shearing edge 310, while the provision of the second groove 521 facilitates the processing of the second shearing edge 510, thereby reducing the difficulty of processing the nozzle pliers.

[0027] Furthermore, the first limiting block 322 protrudes from a side of the first fixing base 320 facing the second fixing base 520 .

[0028] In an embodiment of the present invention, the first limit block 322 protrudes from the side of the first fixing seat 320 facing the second fixing seat 520, so that the first limit block 322 can better contact the second limit block 522, avoiding bite damage to the first shearing edge 310 and the second shearing edge 510.

[0029] Furthermore, the second limiting block 522 protrudes from a side of the second fixing base 520 facing the first fixing base 320 .

[0030] In an embodiment of the present invention, the second limit block 522 protrudes from the side of the second fixing seat 520 facing the first fixing seat 320, so that the second limit block 522 can better contact with the first limit block 322, avoiding bite damage to the first shearing edge 310 and the second shearing edge 510.

[0031] Furthermore, both ends of the first limiting block 322 are flush with the surface of the first fixing seat 320 .

[0032] In an embodiment of the present invention, the two ends of the first limit block 322 are respectively flush with the surface of the first fixed seat 320, which can reduce the number of corners of the structure of the first fixed seat 320, ensure the flatness of the surface of the first fixed seat 320, and reduce the possibility of the first fixed seat 320 scratching the human body or scratching the surface of the injection molded part.

[0033] Furthermore, both ends of the second limiting block 522 are flush with the surface of the second fixing seat 520 .

[0034] In an embodiment of the present invention, the two ends of the second limit block 522 are respectively flush with the surface of the second fixing seat 520, which can reduce the number of corners of the second fixing seat 520 structure, ensure the flatness of the surface of the second fixing seat 520, and reduce the possibility of the second fixing seat 520 scratching the human body or the surface of the injection molded part.

[0035] Furthermore, when the first shearing edge 310 and the second shearing edge 510 come into contact, the first stopper 322 and the second stopper 522 are in surface contact. This ensures the reliability of the limiting function of the first stopper 322 and the second stopper 522, prevents the first shearing edge 310 and the second shearing edge 510 from being damaged by the engagement, and prolongs the service life of the nozzle pliers.

[0036] Furthermore, the first fixing seat 320 and the first limiting block 322 are integrally formed, thereby ensuring the strength of the first fixing seat 320 and improving the processing efficiency of the first fixing seat 320 .

[0037] Furthermore, the second fixing seat 520 and the second limiting block 522 are integrally formed, thereby ensuring the strength of the second fixing seat 520 and improving the processing efficiency of the second fixing seat 520.
