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.

[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 shearing blade 310 is provided with a first groove 321 and a first limiting block 322, the first groove 321 passes through the first shearing blade 310 along the thickness direction of the first shearing blade 310, the first limiting block 322 is located between the first shearing blade 310 and the first groove 321; the second pliers head 50 0, which is connected to the second handle 400, the second pliers 500 includes a second shearing blade 510 and a second fixed seat 520, the second shearing blade 510 is fixedly connected to the second fixed seat 520, the second shearing blade 510 is provided with a second groove 521 and a second limit block 522, the second groove 521 passes through the second shearing blade 510 along the thickness direction of the second shearing blade 510, and the second limit block 522 is located between the second shearing blade 510 and the second groove 521; when the first handle 200 and the second handle 400 are pressed and pivoted around the pivot 100, the first shearing blade 310 contacts the second shearing blade 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 limit block 322 is located on the first shearing edge 310, and the first shearing edge 310 can support the first limit block 322, thereby ensuring the strength of the first limit block 322. The second limit block 522 is located on the second shearing edge 510, and the second shearing edge 510 can support the second limit block 522, thereby ensuring the strength of the second limit block 522. This ensures that the first limit block 322 and the second limit block 522 can avoid bite damage to the first shearing edge 310 and the second shearing edge 510 when cutting the gate material of the injection molded part. Compared with the solution of setting the first groove 321 and the first limit block 322 on the first fixed seat 320, the present application sets the first groove 321 and the first limit block 322 on the first shearing edge 310, which can reduce the length of the first fixed seat 320 and reduce the weight and cost of the nozzle pliers. Compared with the solution of setting the second groove 521 and the second limit block 522 on the second fixed seat 520, the present application sets the second groove 521 and the second limit block 522 on the second shearing edge 510, which can reduce the length of the second fixed seat 520 and reduce the weight and cost of the nozzle pliers.

[0026] The first limit block 322 is located between the first shearing edge 310 and the first groove 321, and the second limit block 522 is located between the second shearing edge 510 and the second groove 521. By setting the first groove 321 and the second groove 521, it can be ensured that the first shearing edge 310 and the second shearing edge 510 can be smoothly engaged, thereby cutting the gate material of the injection molded part.

[0027] Furthermore, the thickness of the first limit block 322 is greater than the thickness of the first shearing blade 310. This can improve the strength of the first limit block, ensure the reliability of the limiting function of the first limit block 322 and the second limit block 522, prevent the first shearing blade 310 and the second shearing blade 510 from being damaged by the engagement, and extend the service life of the nozzle pliers.

[0028] Furthermore, the thickness of the second stopper 522 is greater than the thickness of the second shearing blade 510. This can improve the strength of the second stopper, ensure the reliability of the limiting function of the first stopper 322 and the second stopper 522, prevent the first shearing blade 310 and the second shearing blade 510 from being damaged by the engagement, and extend the service life of the nozzle pliers.

[0029] Furthermore, one end of the first limiting block 322 is flush with the surface of the first fixing seat 320 .

[0030] In an embodiment of the present invention, one end of the first limit block 322 is flush with the surface of the first fixed seat 320, which can reduce the number of corners of the first fixed seat 320 structure, 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 the surface of the injection molded part.

[0031] Furthermore, one end of the second limiting block 522 is flush with the surface of the second fixing seat 520 .

[0032] In an embodiment of the present invention, one end of the second limit block 522 is 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.

[0033] 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.

[0034] Furthermore, the first shearing blade 310 and the first limiting block 322 are integrally formed, thereby ensuring the strength of the first shearing blade 310 and improving the processing efficiency of the first shearing blade 310 .

[0035] Furthermore, the second shearing blade 510 and the second limiting block 522 are integrally formed, thereby ensuring the strength of the second shearing blade 510 and improving the processing efficiency of the second shearing blade 510.
