Silicone mold light point sanding fixture

Abstract

The invention provides a sanding fixture for incident light point of silica gel mold, which includes a base, two first guide rails, a second guide rail, a bottom plate and at least one clamp assembly, the clamp assembly includes a bracket, a third guide rail and at least one clamp ; The two first guide rails are fixed on the base parallel to each other and at intervals; the second guide rail is connected to the two first guide rails through the two first sliders to reciprocate along the two first guide rails, and the second guide rail is perpendicular to the first guide rail ; Two second sliders can be reciprocatingly connected to the second guide rail along the second guide rail, the second sliders form a plurality of connection holes; the clamp assembly is connected to the bottom plate, the bottom plate is fixed on the base, and the clamp can reciprocate along the third guide rail It is movably connected to the third guide rail and connected to the bracket through the third guide rail, and the bracket is connected to the bottom plate. The sanding jig of the light incident point of the silica gel mold of the present invention reduces the difficulty of sanding while ensuring the accuracy; and the bottom plate can be equipped with two jig assemblies at the same time, which improves the sanding efficiency.

Description

technical field [0001] The invention relates to the field of mold manufacturing, in particular to a sanding jig for incident light points of silica gel molds. Background technique [0002] The dimensional accuracy of silicone concentrator products is an order of magnitude higher than that of traditional car lamp injection molding products, and it needs to be assessed by 0.01mm, and the accuracy of the product is also the guarantee of optical performance, so it is necessary to sand the silicone mold to ensure the product quality. quality. Especially the incident point of the silicone mold, the diameter of the mold mandrel is 1.4mm, the required tolerance is ±0.005mm, the size is small, and the precision requirements are high. The above problems have greatly increased the difficulty of sanding. There is no fixed support for traditional sanding, and the coaxiality between the straight gun and the mandrel cannot be guaranteed when sanding the mandrel with an angle, and it is ea...

Problems solved by technology

Especially the light incident point of the silicone mold, the diameter of the mold mandrel is 1.4mm, the tolerance is required to be ±0.005mm, the size is small, and the precision requirements are high. The above problems have greatly increased the difficulty of sanding

There is no fixed bracket for traditional sanding, and the coaxiality between the straight handle gun and the mandrel cannot be guaranteed when sanding the mandrel with an angle, and it is easy to damage the mirror surface of the light incident point of the mold, making sanding very difficult
