Abstract
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] In the prior art, the blade angle of a general sprue pliers is about 49°. However, since the gate material of the injection molded part has a certain thickness, when using the sprue pliers to remove the gate material, the inclined surface of the blade will be subject to greater resistance from the cross-section of the gate material, resulting in workers needing to exert greater grip force to cut the gate material, which is more laborious to use. Utility Model Content
[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a labor-saving nozzle pliers.
[0005] In a first aspect, the nozzle pliers of the present invention include:
[0006] pivot;
[0007] a first handle that pivots about the pivot axis;
[0008] a second handle that pivots about the pivot axis;
[0009] a first pliers head connected to the first handle, the first pliers head comprising a first shearing blade, wherein the blade angle of the first shearing blade is 25 to 37 degrees;
[0010] The second pliers head is connected to the second handle, and the second pliers head comprises a second shearing blade, wherein the blade angle of the second shearing blade is 25-37 degrees.
[0011] According to the technical solution provided in the embodiment of the present application, the blade angle of the first shearing edge is set to 25~37°, and the blade angle of the second shearing edge is set to 25~37°. When using the sprue pliers to cut the pouring material, the resistance of the pouring material cross-section to the first shearing edge and the second shearing edge can be reduced, and the grip force of the worker grasping the first handle and the second handle to drive the first shearing edge and the second shearing edge to cut the pouring material can be effectively reduced, thereby achieving the purpose of saving effort.

[0025] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.
[0026] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0027] An embodiment of the present invention is as follows: Figures 1 to 7 The 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 edge 310, and the blade angle of the first shearing edge 310 is 25 to 37 degrees; a second pliers head 500, which is connected to the second handle 400, the second pliers head 500 includes a second shearing edge 510, and the blade angle of the second shearing edge 510 is 25 to 37 degrees.
[0028] 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 each capable of pivoting about the pivot 100. 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. The first handle 200 and the second handle 400 are then pressed together, which drives the first shearing blade 310 and the second shearing blade 510 toward each other and cuts the sprue material of the injection molded part.
[0029] 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.
[0030] The blade angle of the first shearing edge 310 is set to 25-37 degrees, and the blade angle of the second shearing edge 510 is set to 25-37 degrees. When using the sprue pliers to cut the gate material, the resistance of the gate material cross section to the first shearing edge 310 and the second shearing edge 510 can be reduced, and the gripping force of the worker grasping the first handle 200 and the second handle 400 to drive the first shearing edge 310 and the second shearing edge 510 to cut the gate material can be effectively reduced, thereby achieving the purpose of labor saving.
[0031] Furthermore, the first pliers head 300 is provided with a first limit block 322, and the second pliers head 500 is provided with a 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, the first limit block 322 contacts the second limit block 522.
[0032] In an embodiment of the present invention, when the first shearing edge 310 and the second shearing edge 510 are in contact and the gate material of the injection molded part is cut, the first limit block 322 and the second limit block 522 are in contact with each other, avoiding bite damage caused by excessive contact between the first shearing edge 310 and the second shearing edge 510, thereby extending the service life of the gate pliers.
[0033] Furthermore, the first pliers 300 also includes a first fixed seat 320, the first shearing blade 310 is fixedly connected to the first fixed seat 320, and the first fixed seat 320 is pivotally connected to the pivot 100.

[0034] In an embodiment of the present invention, the first pliers 300 includes a first shearing blade 310 and a first fixing base 320. The first fixing base 320 is pivotally connected to the pivot 100 to enable the first handle 200 to pivot about the pivot 100. The thickness of the first fixing base 320 is greater than the thickness of the first shearing blade 310, ensuring the stability of the pivotal connection between the first fixing base 320 and the pivot 100.
[0035] The second pliers 500 includes a second shearing blade 510 and a second fixing base 520. The second fixing base 520 is pivotally connected to the pivot 100 to enable the second handle 400 to pivot about the pivot 100. The thickness of the second fixing base 520 is greater than that of the second shearing blade 510, ensuring the stability of the pivotal connection between the second fixing base 520 and the pivot 100.
[0036] 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.

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 and second stopper 322 and 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.
[0040] 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.
