Mold for producing lamp frame reflecting body of selenium lamp

Abstract

The invention in particular relates to a die for producing a reflecting body of a lamp frame of a selenium lamp. The invention comprises a terrace die and a cavity die, wherein a die cavity convex surface of the reflecting body of the lamp frame of the selenium lamp is arranged on the terrace die, a die cavity concave surface of the reflecting body of the lamp frame of the selenium lamp is arranged on the cavity die, the terrace die and the cavity die are combined to form a die cavity of the reflecting body of the lamp frame of the selenium lamp, a plurality of slag bags are arranged on a die combining surface of the cavity die, cooling water slots are arranged on the terrace die and the cavity die, a pourer of the die is arranged on the terrace die, the pourer adopts setback type pourer surface, slots are formed on a portion of the pourer which is communicated to the die cavity of the reflecting body of the lamp frame of the selenium lamp, the slag bags are arranged on one side of the concave surface of the die cavity of the reflecting body of the lamp frame of the selenium lamp, the concave surface is corresponded with the pourer, and a plurality of air discharging slots are arranged on the concave die which is on a portion of the slag bags. Due to the structure, the invention has the advantages of good air discharging, reasonable flow diversions of metal fluid, and the metal fluid can be flowed rapidly into the die cavity of the reflecting body of the lamp frame of the selenium lamp, parting surfaces are reasonable, mold openings are convenient, material explosion can be avoided effectively, and mold opening efficiency can be increased.

Description

technical field [0001] The invention relates to a mold, in particular to a mold for manufacturing a lamp frame reflector of a selenium lamp. Background technique [0002] As shown in Fig. 3 and Fig. 4, at present, the die-casting mold used to manufacture the reflector of the lamp frame of the selenium lamp generally includes a die 1 and a punch 2, wherein the die 1 is a movable die, and the punch Die 2 is fixed mould, is provided with selenium lamp lamp frame reflector die cavity convex surface 23 on described punch 2, is provided with selenium lamp lamp frame reflector die cavity concave surface 12 on described die 1, described punch 2 and Die 1 is combined to form the reflector cavity of the lamp frame of the selenium lamp, and the die 1 and the punch 2 at the afterbody of the reflector cavity of the lamp frame of the selenium lamp form a groove-shaped structure that is convex on both sides and concave in the middle. 1 is provided with several slag bags 11, and the slag b...

AI Technical Summary

Problems solved by technology

There are various problems in the structure of the above-mentioned mold for manufacturing the reflector of the lamp frame of the selenium lamp. First, the distribution of the slag bag 11 is unreasonable. , and there is no exhaust groove, the exhaust is not good; the gate 21 is set narrowly, the projected area of ​​the runner is too large, and there is no shunt island, which is not conducive to the reasonable shunting of metal aluminum liquid, and it can quickly enter the cavity of the selenium lamp frame reflector; in selenium The die 1 and the punch 2 at the tail of the reflector cavity of the light frame form a groove-shaped structure with convex sides on both sides and a concave middle in the middle. The parting surface is unreasonable, which shortens the service life of the mold; at the same time, the cooling water channel 3 is too narrow , the cooling effect is poor, it is easy to explode when the mold is opened, the mold opening efficiency is low, and the mold opening time is about 120 seconds
