Abstract

The invention discloses an injection mold for a photoelectric switch shell. The injection mold structurally comprises an upper mold, a plastic guide device, a lower mold and a demolding plate. The injection mold has the beneficial effects that a gas stroking assembly arranged on a liquid extrusion mechanism is used for extruding and stirring injected liquid, so that gas contained in the liquid extrusion mechanism is extruded out, and the phenomenon that due to the gas, the liquid directly rushes into a cavity, and many gas lines appear on the surface of the formed mold, especially the periphery of a water gap is avoided; and by means of an arranged gas stripping structure, gas extruded by the liquid extrusion mechanism moves towards the gas stripping structure and is collected in a concentrated mode under the condition that the gas density is different from the liquid density, and therefore good gas exhausting is achieved.

Description

technical field [0001] The invention relates to the field of injection molds for plastic products, more precisely, it relates to an injection mold for a photoelectric switch housing. Background technique [0002] The photoelectric switch is a kind of blockage or reflection of the light beam by the object to be monitored, and the circuit is connected by a synchronous circuit to monitor the presence or absence of the object, so it has high requirements for the processing of its shell. [0003] When injection molding the photoelectric switch housing, since the working principle of the mold is to directly inject the solution into the mold, it is easy to cause more air marks on the surface of the photoelectric switch housing after molding, and its quality is inferior. uneven. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a photoelectric switch casing injection mold to solve the problem of the p...
