[0003] Aiming at the deficiencies in the background technology, the present invention designs a manufacturing method of a graphite splitter cone used in the process of die-casting an aluminum wheel hub. The diverter cone is easy to corrode and the manufacturing cost is high, which makes the process of using the diverter cone to manufacture the hub extremely easy to damage and needs to be replaced, which leads to the increase of the cost of manufacturing the hub and the increase of labor intensity

Embodiment Construction
[0016] The invention will be further described below with reference to the accompanying drawings.
[0017] Such as Figure 1 to 3 As shown, the present invention discloses a method for producing a graphite shunt cone used in a die-cast aluminum hub, including steps, first step, selecting 1-10 kg of raw material coke, removing sulfur and water in coke by calcination In the second step, the calcined coke after the coke is grinded, and the abrasion is obtained to obtain a diameter of 10-15 microns. The third step is to pour the particles obtained by the grinding into the mixed pot, then inject 20-25% asphalt, then Heating for the adhesive pan, when the temperature of the mixture reaches 160 to 180 degrees Celsius, the stirring is started, the stirring time is 25-30 minutes, then stir mixed with uniform coke and asphalt pour into the extruder, by extrusion machine Pressure forming; fourth step, take out the molded blank, put it in the 18-chamber ribbulating furnace, the calcination tem...

Abstract
The invention discloses a manufacturing method of a graphite sprue spreader used in the manufacturing process of a wheel hub. The manufacturing method comprises the following steps that: 1, 1-10 KG ofraw material coke is selected, and sulphur and water are removed from the coke through a calcination method; 2, the calcined coke is grinded to obtain particles with the diameter being 10-15 micrometers; and 3, the particles obtained by grinding are poured into a kneading pot, then 20-25% of asphalt is injected, then the kneading pot is heated, when the temperature of the kneading pot reaches 160-180 DEG C, stirring starts being conducted for 25-30 min, then the coke and the asphalt which are stirred and mixed evenly are poured into an extruder, and extrusion forming is conducted through theextruder. According to the manufacturing method, the melting point of the adopted graphite can reach 3850+ / -50 DEG C, and the boiling point of the adopted graphite is 4250 DEG C, the graphite sprue spreader is made of graphite, compared with a traditional sprue spreader made of H13 steel, the production cycle is short, heat resistance is achieved, corrosion resistance is achieved, heat conductivity is good, lubrication performance is high, and permeability is low.
Description
Technical field [0001] The present invention relates to the field of die-casting molds, and more particularly to a method for producing a graphite shunt cone used in the die-cast aluminum hub. Background technique [0002] During the production of the hub, the aluminum water will enter the mold cavity through the equipment lifting tube, divided into the various parts of the cavity, and then solidify and cool according to the order, so the shunt cone is critical in the process of making the hub. Role, and currently, the die-cast mold in the market is generally manufactured by H13 steel. This material is joined under high temperature aluminum liquid, which is easy to corrode. When the shunt cone corrodes are damaged, the hub production must be stopped. Die-casting mandrel is fixed to the shunt cone and replaced the new shunt cone, which will increase the labor intensity of the person, extend the wheel production cycle, which cost manpower, leading to the efficiency of the productio...
