Plastic parts welding fixture for automobile instrument components

Abstract

The present invention discloses a plastic parts welding fixture for automobile instrument components, including a cylinder, a connecting board for an projecting end of a cylinder piston rod, a heat insulation board fixed with the connecting board, a heating disk locating behind the heat insulation board, a welding upper mould having a projected welding head and connected with the heating disk, a workstation, a welding lower mould locating above the workstation, a pressure-regulating mechanism locating above the workstation for altering the cylinder piston rod thrust, a timing mechanism for altering the welding time, a temperature control mechanism and an operating panel locating on the side of the cylinder. When working, the cylinder piston rod, the connecting board, the heat insulation board, the heating disk and the welding upper mould move back and forth together along the cylinder piston rod axially. The structure of the invention may be used for the plastic parts welding fixture for automobile instrument components, it is capable of avoiding a welding leakage, a un-solid welding or a overwelding phenomenon, improving the welding efficiency, ensuring the welding quality and reducing the welding cost of a lot production.

Description

technical field [0001] The invention relates to the field of manufacturing automobile instrument parts, in particular to a welding tool for plastic parts that can be used for automobile instrument parts. Background technique [0002] In the plastic manufacturing industry, it is often necessary to weld two plastic parts together because of product assembly or appearance requirements. This requires the use of plastic welding machines, and the current plastic welding machines can only weld at a certain speed when making automotive instrument parts. When it is necessary to improve production efficiency and speed up welding, it will cause welding quality such as missing welding. Problem: The welding pressure and time need to be mastered by the operator, and it is easy to cause weak welding or over-welding, which will affect the welding strength and surface quality, and the welding quality is difficult to guarantee. Contents of the invention [0003] The technical problem to be...
