AI Technical Summary
The injection mold of the traditional optical controller housing needs to be cooled after the injection molding is completed before the core is withdrawn, resulting in the cylinder being energized for a long time to consume a large amount of electricity, increasing production costs and not environmentally friendly and energy-saving.
The core extraction mechanism is adopted, including the core extraction, slider, cylinder and positioning block. The positioning block can be retracted and the slider is fixed by a return spring to ensure that the core extraction is stable during cooling of the workpiece after injection molding is completed, avoiding the cylinder retraction, and realizing the core extraction and retaining after power failure.
Through the design of positioning blocks and return springs, the core extraction mechanism can be maintained stably after power is cut off, saving electricity, and improving the environmental protection and economicality of production.

Abstract
Description
Technical Field
[0001] The utility model belongs to the field of injection molds, and particularly relates to an injection mold for a photoregulator housing. Background Art
[0002] A photoregulator is a device that combines Internet of Things and Internet of Lights technologies and is mainly used to control and adjust lighting devices. The photoregulator housing is usually produced by an injection mold. The mold structure includes an upper template, a lower template, and a core assembly disposed between the upper template and the lower template. The core assembly includes an upper core fixed to the upper template and a lower core fixed to the lower template. A housing cavity is formed between the upper core and the lower core. Since mounting openings are provided at both ends of the photoregulator housing, in order to facilitate mold demolding, the injection of the mounting openings is usually completed by a core-pulling mechanism. The structure of the traditional core-pulling mechanism includes a core and a cylinder connected to the rear end of the core. During mold clamping and injection, the core is ejected by the cylinder; when the injection is completed, the core is retracted by the cylinder. The disadvantages are as follows: Since the workpiece needs to be cooled for a period of time after injection before the core can be retracted, the cylinder has to remain powered on during this period, which consumes a large amount of electric energy, resulting in an increase in production costs and being less environmentally friendly and energy-saving. Summary of the Utility Model
