Description
Technical field
The invention belongs to plasthetics fields, and in particular to a kind of Shooting Technique.
Background technique
Plasthetics is made into plastics, by high-molecular compound made of addition polymerization or polycondensation polymerized, is commonly called as
Plastics or resin can freely change ingredient and body styles.By synthetic resin and filler, plasticizer, stabilizer, lubricant,
The additives such as colorant composition.
Injection molding is a kind of method of industrial products production moulding.Product is usually using rubber injection mold and plastic injection.Injection molding
Molding die platen press and casting die can also be dispensed.Injection (mo(u)lding) machine (abbreviation injector or injection molding machine) is by thermoplastic or heat
The main molding equipment of plastic products of various shapes is made using mould for plastics for solidity material, and injection molding is to pass through injection molding
Machine and mold are realized.
In existing Shooting Technique, due to the influence of pressure, the hot melt colloidal dispersions that will lead in mold are uneven, and
Phenomena such as being easy to appear bubble.
Summary of the invention
Technical problem to be solved by the present invention lies in: in existing Shooting Technique, due to the influence of pressure, it will lead to mould
Hot melt colloidal dispersions in tool are uneven, and phenomena such as be easy to appear bubble.For this purpose, providing a kind of Shooting Technique.
In order to solve the above technical problems, the technical solution of the present invention is as follows:
A kind of Shooting Technique, comprising the following steps:
(1) raw materials such as master batch needed for injection molding are sufficiently mixed uniformly；
(2) raw material that step (1) is uniformly mixed is sucked in materal drier barrel and is dried；
(3) barrel in adapted to injection system is heated to 170~190 DEG C, and the hot flow path in adapted to injection system is heated to 210~
240 DEG C, the cover half in injection mold is heated to 60~70 DEG C, dynamic model is heated to 40~50 DEG C；
(4) dried raw material is added in the barrel after step (3) preheating, molten condition is heated to, by molten condition
Under raw material be injected into the mold after heating by the injection of pretreated hot flow path；
(5) after the completion of raw material injection, opening ultrasonic activation mode makes to contact between molten condition material in mold and sufficiently melt
It closes；
(6) gas vent will be closed after excessive gas discharge in mold by gas vent；
(7) by injecting uniformly carry out pressure maintaining；
(8) it is opened after cooling 5~7s, die sinking pressure is set as 60kg/cm2, dynamic model is opened while hot obtains control panel finished product.
Further, the baking material temperature in step (2) is set as 70~90 DEG C, and the baking material time is set as 3~5h.Drying is
Influence of the moisture content to injection molding in order to prevent.
Further, in step (5) ultrasonic wave frequency control be 18~20kHz, 10~20min of vibration of ultrasonic wave, then
Stand the exhaust process that 30min carries out step (6) again later.
The invention has the benefit that making material mixing more evenly by ultrasonic wave in the present invention, internal combustion is more preferable, keeps away
Exempting from pressure unevenly causes to disperse and mix unevenness between raw material；It also adds and was vented in the technique as described in the invention
Journey can also reduce the probability for bubble occur in final injecting products.
