Abstract
The invention discloses an injection molding method, comprising the following steps: preparing materials and placing the prepared materials into an injection molding machine for injection molding; adding dispersing oil into the raw material, wherein, the adding amount of the dispersing oil is as follows: 2-4g of dispersing oil is added in 1g of raw material; adding 1.4-1.8g of toner to 1g of raw material; and evenly stirring for 5-20 minutes for injection molding. Compared with the existing method, the method is characterized by comprising the following steps: preparing materials and placing into an injection molding machine for injection molding; adding dispersing oil into the raw material in preparing the materials, wherein, the adding amount of the dispersing oil is as follows: 2-4g of dispersing oil is added in 1g of raw material; adding 1.4-1.8g of toner to 1g of raw material; and evenly stirring 5-20 minutes for injection molding; and replacing the original white oil by the dispersing oil. The raw material is easier to disperse in stirring, the chemical stability of the dispersing oil is more stable, thus the antioxidant performance is good in injection molding, black spots can not occur on the product, and the property of the dispersing oil plays the effects of releasing agent.
Description
Technical field:
The present invention relates to a kind of injection moulding process.
Background technology:
The injection moulding process of prior art improves the light of product surface after the injection moulding with white oil as additive when injection moulding, but the toner in the starting material easily after through the high temperature extruding, finished product is easy to generate stain, and color and luster is inhomogeneous.
Summary of the invention:
The present invention is directed to above problem provides a kind of finished product the uniform injection moulding process of stain and color and luster can not occur.
The present invention overcomes the above problems used technical scheme: a kind of injection moulding process is provided, during batching, adds dispersed oil in raw material, the dispersed oil add-on is: every kg feed material adds the dispersed oil of 2 grams~4 grams; Ratio in every kg feed material 1.4 grams~1.8 grams adds toner subsequently, and stirs evenly back injection moulding in 5 minutes~20 minutes.
Described dispersed oil add-on is: every kg feed material adds the dispersed oil of 2.5 grams~3 grams.
Described churning time is 10 minutes.
After adopting above method, the present invention compared with prior art during owing to batching, adds dispersed oil in raw material, and the dispersed oil add-on is: every kg feed material adds the dispersed oils of 2 grams~4 grams; Ratio in every kg feed material 1.4 grams~1.8 grams adds toner subsequently, and stir evenly back injection moulding in 5 minutes~20 minutes, after then using dispersed oil to replace original white oil, the easier dispersion of raw material when stirring, and the chemical stability of dispersed oil is more stable, so oxidation-resistance is better during injection moulding, product blackspot can not occur; The dispersed oil self-characteristic has also played the effect of releasing agent simultaneously.Therefore the product of the present invention's production stain can not occur, and color and luster is also even.
Embodiment:
Below in conjunction with concrete real mode, the present invention is described further:
Embodiment 1
A kind of injection moulding process during batching, adds dispersed oil in raw material, dispersed oil is a commercially available German Wei Kai company, AK1000 type dispersed oil, and the dispersed oil add-on is: every kg feed material adds the dispersed oils of 2 grams; Ratio in every kg feed material 1.4 grams adds toner subsequently, and stirs evenly back injection moulding in 5 minutes, and injection moulding program afterwards is identical with the conventional injection moulding process of prior art, as the raw material after stirring dries by the requirement that will produce product, and puts into head tank; The subsequent start-up injection moulding machine carries out matched moulds; Then inject, and pressurize; With postcooling; Carry out die sinking after the cooling; By mold pushing mechanism product is ejected at last.
Embodiment 2
A kind of injection moulding process during batching, adds dispersed oil in raw material, the dispersed oil add-on is: every kg feed material adds the dispersed oil of 3 grams; Ratio in every kg feed material 1.6 grams adds toner subsequently, and stirs evenly back injection moulding in 15 minutes, and injection moulding program afterwards is identical with the conventional injection moulding process of prior art.
Embodiment 3
A kind of injection moulding process during batching, adds dispersed oil in raw material, the dispersed oil add-on is: every kg feed material adds the dispersed oil of 4 grams; Ratio in every kg feed material 1.8 grams adds toner subsequently, and stirs injection moulding after 20 even minutes, and injection moulding program afterwards is identical with the conventional injection moulding process of prior art.
Above production unit all adopts the production unit of routine techniques.
