Embodiment 1

[0041] refer to figure 1, a hot-melt assembly fixture for injection molded parts, including 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 fixed on On the carrier plate 3, a driving member (not shown in the figure) is connected with 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 with figure 2 , the top plate mechanism 1 includes a heating assembly 14 , a fixing plate 11 , several adjusting assemblies 12 and several heat-melting 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, and the accommod...

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 horizontal adjustment block 121 and the longitudinal adjustment block 122 . In this embodiment, one adjustment assembly 12 includes four limiting members 126, and one limiting member 126 includes a limiting plate 1261 and two bolts. The two limiters 126 are arranged at both ends of the longitudinal adjustment block 122 in the length direction, and the limit plate 1261 covers the horizontal adjustment block 121 and the longitudinal adjustment block 122 at the same time, and is fixedly connected to the horizontal adjustment block 121 by bolts. The two limiters 126 are respectively arranged on the opposite ends of the transverse adjustment block 121 , and the limit plates 1261 cover the transverse adjustment block 121 and the fixing plate 11 at the same time, and are fixedly connected to the fixing plate 11 by ...

Abstract

The invention relates to the technical field of jigs, in particular to an injection molding part hot melting assembly jig. According to the key points of the technical scheme, the injection molding part hot melting assembly jig comprises a top plate mechanism, a bottom plate mechanism and a driving part, the top plate mechanism is located above the bottom plate mechanism, and the top plate mechanism comprises a heating assembly, an adjusting assembly, a hot melting column and a fixing plate; and the heating assembly and the adjusting assembly are both fixedly connected with the fixing plate, the hot melting column is fixedly arranged on the adjusting assembly, the adjusting assembly is used for adjusting the position of the hot melting column, and the driving part is used for driving the top plate mechanism to be close to or away from the bottom plate mechanism. The injection molding part hot melting assembly jig has the effect that the position of the hot melting column can be adjusted, so that the welding quality is improved.

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 melting refers to the method of heating part of the plastic workpiece to a fluid state and then fixedly connecting it with the welding body. [0003] In the related art, the welding body is usually provided with several through holes, and the workpiece is usually provided with several welding columns 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 contact the welding column. The hot-melt column heats the welding column and melts it into a fluid hot-melt adhesive. The hot-melt adhesive often covers the through-h...
