The waveform chamber wall injection molding die comprises a die, wherein the die comprises a die chamber surrounded with chamber walls; and at least two streamline bulges are arranged inside the chamber walls. According to the technical scheme, by adopting a plastic part manufactured through the waveform chamber wall injection molding die and internally provided with a printing circuit film, a printing circuit in the printing circuit film is ensured to meet the smoothness, and the printing circuit film is prevented from being subjected to falling, oxidization and leakage of solvent micromolecules, and the environmental friendliness and the durability are ensured.
Description
Technical field
The utility model relates to the injection-moulding device technical field, relates in particular to a kind of mould.
Background technology
Mould is one of important tool in the injection mo(u)lding, and injection mo(u)lding is that the plastics with the melting attitude inject at a high speed in the mould, treats that plastic cool solidifies, and opens mould the plastic product that solidifies is ejected, to obtain the processing method of shaped article.The moulding expense is low because the injection mo(u)lding processing method has, molding cycle is short, forming process is simple and be easy to the complicated characteristics such as plastic product of forming shape, therefore is widely used in the plastic product application.
When adopting printed circuit film and plastics to carry out the integrated through injection molding metallization processes; The plastics of molten condition inject in the mould down through the pressure of tens handkerchiefs; Give the pressure and the frictional force on printed circuit film surface very big; Printed circuit film can be with the extension elongation that flows to of molten state plastics under the multiple active force of thermal expansion, pressure and frictional force, and prolongation is finally at plastically welding point gauffer and embed in the plastics.Because printed circuit film state at high temperature is weak, the wrinkle the top of the horn of fold place is sharp, has exceeded the permission knuckle of the silver slurry circuit in the printed circuit film, makes circuit open circuit easily.
The utility model content
The purpose of the utility model is, a kind of wave chamber wall injection mold is provided, and solves above technical problem.
The technical problem that the utility model solved can adopt following technical scheme to realize:
Wave chamber wall injection mold comprises a mould, and said mould comprises the die cavity that surrounded by the chamber wall, it is characterized in that wall inboard, said chamber is provided with at least two streamlined convexities.
Under the prerequisite that does not change the moulding primary structure,, sponge part and then fold that printed circuit film is stretched and prolongs in injection moulding process, the sharp-pointed wrinkle angle of particularly eliminating fold place on mold cavity wall through at least two streamlined convexities are set.
At least two said streamlined protruding connections, form a waveform bending structure.So that better absorb the extension elongation part of printed circuit film.Make the whole piece printed circuit film smoothly paste clothes, and be combined as a whole securely with plastic.So both guaranteed circuit clear, guaranteed again that printed circuit film does not come off, not oxidation, solvent-free little molecule overflow environmental protection and durable.
At least be distributed with two groups of waveform bending structures that are formed by connecting said streamlined convexity on the wall of said chamber.So that evenly absorb the part that printed circuit film is stretched and prolongs in injection moulding process.
Be distributed with four groups of waveform bending structures that are formed by connecting said streamlined convexity on the wall of said chamber.So that further evenly absorb the part that printed circuit film is stretched and prolongs in injection moulding process.
Said chamber wall comprises chamber, the outside wall that is positioned at the inboard inboard chamber wall of said die cavity and is positioned at the said die cavity outside, and said shape wave bending structure is arranged on the wall of inboard chamber.Unaffected to guarantee moulding outboard structure outward appearance.
Said die cavity outboard structure is a quadrangle, and said die cavity inboard is a quadrangle, and four said waveform bending structures are separately positioned on the four edges of inboard chamber wall.
The place of taking back, wall middle part, said inboard chamber is provided with a connection chamber, the both sides, front and back of said connection chamber UNICOM said inboard chamber wall.Said connection chamber is a strip.
Said chamber wall comprises chamber, the outside wall that is positioned at the inboard inboard chamber wall of said die cavity and is positioned at the said die cavity outside, and said waveform bending structure is arranged on the wall of chamber, the outside.Unaffected to guarantee the moulding inside structure.
Beneficial effect: owing to adopted technique scheme; The plastic that is built-in with printed circuit film that adopts the utility model to process; Both guaranteed that the printed circuit in the printed circuit film was unimpeded, guaranteed again that printed circuit film does not come off, not oxidation, solvent-free little molecule effusion, environmental protection and durable.
Description of drawings
Fig. 1 is the structural representation of the utility model die cavity.
The specific embodiment
Technological means, the creation characteristic of realizing for the utility model, reach purpose and be easy to understand understanding,, further set forth the utility model below in conjunction with concrete diagram with effect.
With reference to Fig. 1, wave chamber wall injection mold comprises a mould, and mould comprises the die cavity that surrounded by chamber wall 11, and wall 11 inboards in chamber are provided with at least two streamlined convexities.Under the prerequisite that does not change the moulding primary structure, through at least two streamlined convexities are set, sponge the part that printed circuit film is stretched and prolongs in injection moulding process on mold cavity wall 11, so that fold, the sharp-pointed wrinkle angle of particularly eliminating fold place.
At least two streamlined protruding connections, form a waveform bending structure 2.So that better absorb the extension elongation part of printed circuit film.Make the whole piece printed circuit film smoothly paste clothes, and be combined as a whole securely with plastic.So both guaranteed circuit clear, guaranteed again that printed circuit film does not come off, not oxidation, solvent-free little molecule overflow environmental protection and durable.
At least be distributed with two groups of waveform bending structures 2 that are formed by connecting streamlined convexity on the chamber wall 11.So that evenly absorb the part that printed circuit film is stretched and prolongs in injection moulding process.With reference to Fig. 1, be distributed with four groups of waveform bending structures 2 that are formed by connecting streamlined convexity on the chamber wall 11.So that further evenly absorb the part that printed circuit film is stretched and prolongs in injection moulding process.
With reference to Fig. 1, chamber wall 11 comprises chamber, the outside wall that is positioned at the inboard inboard chamber wall of die cavity and is positioned at the die cavity outside, and waveform bending structure 2 is arranged on the wall of inboard chamber.Unaffected to guarantee moulding outboard structure outward appearance.The die cavity outboard structure is a quadrangle, and said die cavity inboard is a quadrangle, and four waveform bending structures 2 are separately positioned on the four edges of inboard chamber wall.
The place of taking back, wall middle part, inboard chamber is provided with a connection chamber 12, the both sides, front and back of connection chamber 12 UNICOMs inboard chamber wall.Connection chamber 12 is a strip.
