Abstract

The invention relates to a manufacturing method of an LED lamp body, and provides a method and a device for achieving automatic production of an integrated body of a close nipple and metal heat dissipation parts, so as to reduce processes and increase the work efficiency. According to the technical scheme, heat dissipation inserts and a connector screw blank are separately positioned at a mold core of an injection moulding device; the mold cavity inner wall of the mold core, corresponding to the connector screw blank, is provided with a screw thread; plastic is injected into the mold cavity; the connector screw blank, under extrusion of the plastic, is deformed into an interface with a screw thread; and the interface with the screw thread and a metal lamp cup are connected into one part by the plastic. The lamp cup can be deformed in the injection moulding process, or the metal lamp is provided with a groove to which the plastic is added so as to enhance the strength.

Description

The LED lamp body preparation method of the many built-in types of one, extrusion modling lamp holder
Technical field
The present invention relates to a kind of manufacture method of LED lamp body.
Background technology
Bulb lamp lamp source is the earliest people's use habit, in existing environment, manufacturer no matter, field of employment is all equipped with the service condition of bulb lamp, and LED light fixture has power savings advantages to be recommended energetically, and moulding and the structure of LED lamp being made to bulb lamp have more convenient environment for use.But LED light source is different with existing tengsten lamp as bulb lamp, and it also will have metal heat sink, to meet the requirement in LED lamp source, meanwhile, with existing tengsten lamp, equally will have hickey.In the present mode of production, the two is manufactured respectively, combines, and its operation is many, and manufacturing cost is high.
Summary of the invention
Object of the present invention provides a kind of hickey to be made into integration with metal heat sink automatic production method and the equipment realized, and reduces operation, increases work efficiency.
Technical scheme of the present invention is that heat radiation inserts, interface spiral shell base are located respectively on the core of being located at injection-moulding device, the die cavity wall of described core corresponding interface spiral shell base is provided with screw thread, to injected plastic in die cavity, interface spiral shell base is deformed into threaded interface under the extruding of plastics, and plastics connect as one hickey and metalized lamp cup.
Described Lamp cup also can be out of shape in injection moulding process, or at metalized lamp cup, groove is set and adds plastics to gain in strength.
Thus, the present invention completes the formation of metal interface screw thread in the lump in injection moulding operation, has saved operation, the metal interface connection function that mainly electrifies simultaneously, and materials are economized.
Accompanying drawing explanation
Fig. 1 is mould of the present invention and insert structure schematic diagram;
Fig. 2 is general assembly drawing of the present invention.
The specific embodiment:
As shown in Figure 1: the LED Lamp cup mould of the present embodiment comprises glue muzzle 1, panel 2, stripper plate 3, upper inserts 4, plastic substrate 5, lower inserts 6, left, right slide block 7, A plate 8, B plate 9, core 10, supporting plate 11, thimble 14, upper needle plate 12, lower needle plate 12, base plate 13, upper inserts 4 is interface spiral shell base, left, right slide block inwall is shaping screw thread, lower inserts 6 is heat radiation lamp cup, upper inserts, lower inserts is metalwork, be positioned respectively on mold cores, to injection moulding in die cavity, plastics push inserts 4 from inside to outside, the external screw thread of inserts on forming in injection moulding, injection moulding completes the plastic substrate of formation by upper inserts 4, lower inserts 6 is linked as integral body, become the matrix of LED lamp.
