Embodiment 1

[0041] refer to figure 1, a hot-melt assembly fixture for injection molded parts includes a top plate mechanism 1, a bottom plate mechanism 2, a carrier plate 3 and a driver (not shown in the figure), the top plate mechanism 1 is located directly above the bottom plate mechanism 2, and the bottom plate mechanism 2 is fixedly arranged in On the carrier board 3, a driving member (not shown in the figure) is connected to the top plate mechanism for driving the top plate mechanism 1 to approach or move away from the bottom plate mechanism 2 in the vertical direction. The driving member can be set as an air cylinder in the prior art.

[0042] refer to figure 1 and figure 2 , the top plate mechanism 1 includes a heating assembly 14 , a fixing plate 11 , a plurality of adjustment assemblies 12 and a plurality of hot-melt columns 13 . The fixing plate 11 is arranged in the shape of a rectangular parallelepiped, and there are several accommodating grooves 111 on the fixing plate 11 ...

Embodiment 2

[0058] refer to Image 6 The difference between this embodiment and Embodiment 1 is that the adjustment assembly 12 further includes a limiting member 126 for limiting the lateral adjustment block 121 and the longitudinal adjustment block 122 . In this embodiment, one adjusting assembly 12 includes four limiting members 126 , and one limiting member 126 includes a limiting plate 1261 and two bolts. The two limiting members 126 are disposed at both ends of the longitudinal adjusting block 122 in the length direction. The limiting plate 1261 covers the lateral adjusting block 121 and the longitudinal adjusting block 122 at the same time, and is fixedly connected to the lateral adjusting block 121 by bolts. The two limiting members 126 are respectively disposed at opposite ends of the lateral adjustment block 121 , and the limiting plates 1261 cover the lateral adjustment block 121 and the fixing plate 11 at the same time, and are fixedly connected to the fixing plate 11 by bolts...

Abstract

The present application relates to the technical field of jigs, and specifically discloses a hot-melt assembly jig for injection molded parts. The technical solution of the jig is as follows: it includes a top plate mechanism and a bottom plate mechanism driver, and the top plate mechanism is located above the bottom plate mechanism, so the The top plate mechanism includes a heating assembly, an adjustment assembly, a hot-melt column and a fixing plate, the heating assembly and the adjustment assembly are fixedly connected to the fixing plate, and the hot-melt column is fixedly arranged on the adjustment assembly, so The adjusting assembly is used for adjusting the position of the hot-melt column, and the driving member is used for driving the top plate mechanism to approach or move away from the bottom plate mechanism. The present application has the effect of making the position of the hot-melt column adjustable, thereby improving the quality of welding.

Description

technical field [0001] The present application relates to the technical field of jigs, in particular to a hot-melt assembly jig for injection molded parts. Background technique [0002] Because the hot-melt process has the advantages of simple operation and low processing cost, the hot-melt process is widely used in the assembly and production of plastic workpieces. Hot fusion refers to the way in which part of the plastic workpiece is heated to a fluid state and then fixedly connected to the fusion body. [0003] In the related art, the welding body is usually provided with a number of through holes, and the workpiece is usually provided with a number of welding posts for welding. In the through hole of the main body, the high-temperature hot-melt column located in the hot-melt fixture is driven by the driver to abut with the welding column, and the hot-melt column heats and melts the welding column into a fluid hot-melt adhesive. At the periphery of the hole and the thro...
