Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses tool is used in runner department runner and inclined plane detection. Referring to fig. 2 and 3, a runner department runner and inclined plane detect and use tool includes locating lever 1, the one end of locating lever 1 is provided with toper test head 2, the lateral wall inclination angle of toper test head 2 is the same with the inclination of the interior passageway of standard hot mouth body 101, and then make this moment only need with locating lever 1 vertical placement, then establish hot mouth body 101 cover on toper test head 2, the runner width and the interior passageway inclination of hot mouth body 101 runner department 103 are judged to the length that stretches out hot mouth body 101 through observing toper test head 2, if interior passageway inclination is less than the gradient of standard design, then toper test head 2 can't normally stretch out, if the interior passageway inclination is greater than the gradient of standard design then the contact point between toper test head 2 and the hot mouth body 101 only be the runner round, consequently can paint red lead on the test head, observe the red lead circumstances that drops, if red lead is only red circle then unqualified. If the red trace is not a circle, observing the extension length of the test port, if the length is long, the diameter of the gate does not meet the requirement, and if the length is short, the diameter of the gate does not meet the requirement. Therefore, in order to facilitate the observation of whether the extending length of the chewing core test head meets the requirement, two wiring scales 22 can be arranged on the side wall of the conical test head 2, the extending part between the two limit scales 22 meets the requirement, and if not, the extending part does not meet the requirement. Meanwhile, in order to test the hot nozzle bodies 101 with different sizes, the scale 22 can be marked on the side wall of the conical test head 2, that is, the extension length can be directly judged by observing the scale 22, so that the test requirements of the hot nozzle bodies 101 with different sizes can be met.

Referring to fig. 2 and 3, in order to prevent the hot nozzle body 101 from tilting during testing to cause inaccurate testing, on one hand, the verticality of the positioning rod 1 needs to be ensured. Consequently, locating lever 1 is kept away from 2 one ends of toper test head and is fixed with backup pad 3, and equidistant distribution has four support swivel nuts 4 on the base of backup pad 3, and equal spiro union has supporting legs 5 in every support swivel nut 4, and then guarantees the levelness of backup pad 3 through adjustment supporting legs 5 extension length to guarantee the verticality of locating lever 1.

Referring to fig. 2 and 3, the supporting plate 3 is provided with four guide rods 6 on the side away from the supporting legs 5, each guide rod 6 is parallel to the positioning rod 1, and the four guide rods 6 are provided with lifting plates 8 in a penetrating manner, so that the lifting plates 8 can move back and forth along the axial direction of the positioning rod 1. Lifting board 8 is fixed with the position sleeve 9 of cover on locating lever 1, set up on the position sleeve 9 and supply screw thread portion 102 male constant head tank 91, constant head tank 91 diameter portion 102 diameter 1-2MM bigger than screw thread portion, thereby can insert the screw thread portion 102 of hot mouth body 101 in constant head tank 91 when making lifting board 8 reciprocate, then lifting position sleeve 9, thereby make position sleeve 9 drive hot mouth body 101 horizontal migration from top to bottom, and then guarantee that hot mouth body 101 can not take place the skew, and then guarantee the accuracy of test.

The implementation principle of the jig for detecting the sprue and the inclined plane of the sprue department in the embodiment of the application is as follows: firstly, the positioning rod 1 is adjusted to be vertical through the supporting leg 5, and then the hot nozzle body 101 is inserted into the positioning rod 1 through the positioning sleeve 9. Observing the length of the conical test head 2 extending out of the hot nozzle body 101 to judge the gate width and the inner channel inclination of a gate driver 103 of the hot nozzle body 101, wherein if the inner channel inclination is smaller than the standard design inclination, the conical test head 2 cannot extend normally, and if the inner channel inclination is larger than the standard design inclination, the contact point between the conical test head 2 and the hot nozzle body 101 is only one gate circle, so that red can be smeared on the test head, the falling condition of the red can be observed, and if the red mark is only one red circle, the red mark is unqualified; if the red trace is not a circle, the extension length of the conical test head 2 is observed, if the length is longer, the diameter of the gate is not satisfactory, and if the length is shorter, the diameter of the gate is not satisfactory.
