Embodiment Construction

[0007] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0008] Such as figure 1 As shown, a TV dust cover plastic mold provided by the embodiment of the present invention is characterized in that the unilateral escape of the thin nozzle flow channel 1 of the TV dust cover plastic mold is greater than 0.11mm. After increasing the avoidance, the misalignment caused by assembly tolerance can be overcome.

[0009] The inventors have found through many experiments that the effect is best when the unilateral displacement of the fine runner channel 1...

Abstract

The invention provides a plastic mold for dust covers of television sets. The plastic mold is characterized in that single-side avoidance of a runner of a pin-point gate of the plastic mold for the dust covers of the television sets is larger than 0.11mm. After the avoidance is enlarged, dislocation caused by assembly tolerance can be overcome. After the plastic mold is modified, dislocation of sprues is avoided, the sprues cannot be broken, and accordingly production efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a plastic mold for a dust-proof cover of a TV set. Background technique [0002] In the current design of the fine nozzle flow channel of the plastic mold for the dust cover of the TV set, the unilateral gap is only 0.11mm in the design. Since this part is matched with the template, the tolerance is relatively large, resulting in misalignment of the holes in the matching part, resulting in The head will break off. Contents of the invention [0003] In order to solve at least one of the above-mentioned problems, the present invention proposes a plastic mold for a TV dust cover, characterized in that the unilateral escape of the fine nozzle flow channel of the plastic mold for the TV dust cover is greater than 0.11 mm. After increasing the avoidance, the misalignment caused by assembly tolerance can be overcome. After the technology is improved, partial dislocation of th...
