Automatic grinding device for plastic part joint lines

Abstract

The invention discloses an automatic grinding device for plastic part joint lines. The automatic grinding device comprises a machine table, a mechanical arm and a grinding device body, the mechanicalarm is arranged on the machine table, the grinding device body is arranged at the end of the mechanical arm and can freely rotate by 360 degrees, the grinding device body comprises a coarse-grinding mechanism, the coarse-grinding mechanism comprises a coarse-grinding driving cylinder, a coarse-grinding pneumatic cam, a coarse-grinding base, a coarse-grinding elasticity grinding head and raw emerypaper, the coarse-grinding pneumatic cam is connected to the coarse-grinding driving cylinder, the coarse-grinding base is connected to the coarse-grinding pneumatic cam, the coarse-grinding elasticity grinding head is arranged on the outer end surface of the coarse-grinding base, the raw emery paper is stuck on the outer end surface of the coarse-grinding elasticity grinding head, the coarse-grinding driving cylinder and the coarse-grinding pneumatic cam drive the coarse-grinding elasticity grinding head to move along a preset grinding track in a vibration manner, and the joint lines on the plastic parts are comprehensively and coarsely grinded by the raw emery paper on the end surface of the coarse-grinding elasticity grinding head in a vibration manner. According to the automatic grinding device, the joint lines can be comprehensively, seamlessly, rapidly, accurately, coarsely and finely grinded. Compared with a manual grinding mode, grinding efficiency is greatly improved, and grinding accuracy is improved.

Description

Technical field [0001] The invention relates to a polishing equipment, in particular to an automatic polishing equipment for a plastic part moulding line. Background technique [0002] The parting line is also called the flashing line. Excess plastic flows out at the joint of the mold, leaving visible traces after cutting off the overflow. Sometimes it is called the mold mark or the interface line core. It also refers to the gap between the mold parts due to the material flowing into the mold. The seam produced on the plastic or casting, or the joint under the main model of the plastic mold, is used to indicate that the plastic mold is divided into two halves or several parts. [0003] The parting line seriously affects the appearance of the plastic parts, so the plastic parts must be polished before plating and spraying. For a long time, the grinding of plastic parts is generally manual grinding with grinding consumables, or hand-held plastic parts are ground on a grinding machin...

AI Technical Summary

Problems solved by technology

For a long time, the grinding of plastic parts has generally been done manually with grinding consumables, or with hand-held plastic parts on a grinder. This method of grinding the mold line is expensive, time-consuming, and extremely inefficient, and the grinding effect is difficult to meet the requirements.
