Abstract
An aluminothermic forming die for blow-molded face shields of domestic ceiling lamps comprises an upper die and a bottom die. Side dies are arranged between edges of the upper die and the bottom die, a cavity consistent with the outer surface of a blow-molded face shield is arranged on the inner side of the upper die, a movable pre-molding structure block is arranged in a core which is arranged on the inner side of the bottom die, and a porous passage allowing external compressed air to enter the cavity is arranged in the bottom die. A temperature control system for adjusting temperature during forming of the blow-molded face shield is disposed in the upper die. The movable pre-molding structure block arranged in the core of the aluminothermic forming die is used for pre-stretching and pre-forming of plates, and the temperature of each part of the plates can be controlled precisely by the aid of the temperature control system for adjusting temperature, so that walls of products are uniform in thickness.
Description
Technical field
The utility model relates to a kind of household lamp affixed to the ceiling blowing face shield aluminothermy mould.
Background technology
Manufacture process such as Fig. 1, shown in Figure 2 of conventional lamp affixed to the ceiling blowing face shield, employed mould is made up of patrix 111, bed die 112 and Bian Mo 113, and compressed air gets into from bed die 112, and with sheet material 120 blow moldings, after formed product, its shortcoming is mainly following:
1. product thick middle, thin edge, the edge mechanical strength is relatively poor, and is broken easily;
2. light transmittance is inhomogeneous, causes Illumination Distribution inhomogeneous.
The utility model content
The purpose of the utility model provides a kind of household lamp affixed to the ceiling blowing face shield aluminothermy mould, uses this mould, can greatly improve the uniformity of product wall thickness, strengthens mechanical strength, reduces breakage rate, makes Illumination Distribution more even.
The utility model is that the technical scheme that its technical problem of solution is adopted is,
Household lamp affixed to the ceiling blowing face shield aluminothermy mould; Comprise patrix and bed die; Be provided with the limit mould between the edge of patrix and bed die, the patrix inboard is provided with and the consistent die cavity in blowing OFP surface, and the bed die inboard is provided with core; Be provided with movably preform constructions piece in the said core, be provided with the duct that supplies the external compression air to get into die cavity in the bed die.
Said patrix set inside has in blowing face shield forming process carries out thermoregulator temperature control system.
The sheet material that is used to make the blowing face shield places between patrix and the bed die, and compressed air gets into from bed die, with the sheet material blow molding.When compressed air blew, core moved up, and made upwards protuberance of sheet material, and the preform constructions piece moves to the left and right, makes the sheet material transversely deforming, the temperature at each position of temperature control system adjustment extrusion board, the uniformity of each position thickness of assurance face shield.
The beneficial effect of the utility model is; This mould is provided with movably preform constructions piece in core, sheet material is carried out prestretched and preformed, utilizes temperature control system to carry out adjustment simultaneously; Temperature to each position of sheet material is precisely controlled, and makes the product wall thickness even.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand with effect and understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.
Like Fig. 3, Fig. 4, shown in Figure 5; The household lamp affixed to the ceiling blowing face shield aluminothermy mould that the utility model proposes comprises patrix 210 and bed die 220; Be provided with limit mould 230 between the edge of patrix 210 and bed die 220, patrix 210 inboards are provided with and the consistent die cavity in blowing OFP surface, and bed die 220 inboards are provided with core 221; Be provided with movably preform constructions piece 222 in the said core 221, be provided with the duct 223 that supplies the external compression air to get into die cavity in the bed die 220.Patrix 210 set inside have carries out thermoregulator temperature control system 211,212 and 213 in blowing face shield forming process.
The sheet material 300 that is used to make the blowing face shield places between patrix 210 and the bed die 220, and compressed air gets into from bed die 220, with sheet material 300 blow moldings.When compressed air blew, core 221 moved up, and made upwards protuberance of sheet material 300; Preform constructions piece 222 moves to the left and right; Make sheet material 300 transversely deformings, the temperature at each position of temperature control system adjustment extrusion board, the uniformity of each position thickness of assurance face shield.Temperature control system 211 remains between 100 ℃～160 ℃ the temperature of sheet material central region, and temperature control system 212 and 213 remains between 30 ℃～50 ℃ the sheet edge regional temperature.
This mould is provided with movably preform constructions piece in core; Sheet material is carried out prestretched and preformed; Utilize temperature control system to carry out adjustment simultaneously, the temperature at each position of sheet material is precisely controlled, like Fig. 6, shown in Figure 7; Show through experiment, the thickness evenness of blowing face shield is improved a lot.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
