I principali  plastica stampaggio ad iniezione di componenti  contiene tutte le parti che entrano in contatto con le parti di plastica che devono essere trattati esattamente con la precisione necessaria per assicurare l'efficienza e la stabilità del processo di stampaggio ad iniezione. Queste parti includono le anime dello stampo, la cavità, gli inserti, il sollevatore e i cursori.

La lavorazione per l'anima e la cavità dello stampo

1) Preparazione dei materiali dello stampo;

2) Milling machine processing: Drilling and transporting water holes (the distance between the deepest end of the water transporting plug and the horizontal water transporting hole is 3-4mm), threading holes, drilling, tapping screw holes, drilling, pin holes, mold number, reference angle , Give up;

3) CNC machining: rough machining;

4) Heat treatment: indicate the hardness requirements;

5) Grinding machine: Grind a six-sided square, and the size shall be ground to the size of the frame. The dimensions in the upward direction are added to the drawing (minus 0.03mm-0.05mm) ⊥0.01, ， 0.01, the part that can be shaped by the grinding machine must be ground and formed;

6) If CNC core machining is required, arrange CNC finishing, if the cavity has fonts and mold numbers, lettering processing is required;

7) Elaborazione del taglio del filo: fori dell'inserto di lavorazione del filo centrale, fori superiori obliqui, fori del ditale, fori di spillo, ecc.;

8) Elaborazione EDM: elaborazione singola secondo disegni e istruzioni a impulsi;

9) Elaborazione della lucidatura: scrivere il piano di lucidatura e i requisiti sulla scheda del processo, utilizzare un pennarello per contrassegnare l'area lucidata sul pezzo in lavorazione, se i requisiti dello specchio sono troppo tardi, è possibile lanciare lo stampo di prova e quindi finire la lucidatura;

10) Assemblare lo stampo di prova.

Lavorazione di inserti in stampaggio a iniezione

1) Preparazione dei materiali: L'artigiano definisce se lavorare un pezzo singolo o più pezzi insieme a seconda delle dimensioni e della forma del pezzo. Se più pezzi vengono lavorati insieme, l'artigiano deve mappare la posizione di lavorazione del pezzo;

2) Milling processing: The fitter performs the processing according to the workpiece drawing or the layout chart issued by the technician, drilling and transporting water holes (the deepest part of the water transport plug is 3-4mm from the horizontal water transport hole), threading holes, drilling, Tapping screw holes, drills, pinholes, thickened parts, mold numbers, and concessions.

3) CNC machining: if CNC rough machining is required, arrange CNC rough machining;

4) Heat treatment: indicate the hardness requirements;

5) Grinding machine processing: Grind a six-sided square, the part must be ground and formed;

6) For CNC-finished workpieces, arrange CNC finishing,if the insert has a font and mold number, lettering processing is required;

7) Wire cutting EDM processing: middle wire processing insert holes, oblique top holes, thimble holes, etc .;

8) EDM: single processing according to drawings and pulse instructions;

9) Elaborazione della lucidatura: scrivere il piano di lucidatura e i requisiti sulla scheda del processo, utilizzare un pennarello per contrassegnare l'area lucidata sul pezzo in lavorazione, se i requisiti dello specchio sono troppo tardi, è possibile lanciare lo stampo di prova e quindi finire la lucidatura;

10) Assemble the test mold.

Special-shaped insert processing technology

1) Wire-cutting processing: Medium wire cutting with exact dimensions (A / B view), pull-tab, grinder with thickness allowance, and roughing at the molding place;

2) Grinding machine processing: grind the thickness, slope, forming;

3) EDM processing;

Polishing.

Mold lifts machining

1) Wire cutting processing: the shape of the middle wire cutting, the head is left to the grinding surface and the remaining size is ground, and the remaining dimensions are ground accurately.

2) Grinding machine processing: grind thickness and I-groove;

3) Assembly;

4) EDM processing;

5) Polishing;

6) Milling machine oil groove.

Mold machining of Lift block

1) Fitter preparation: 1.5mm on both sides of the height dimension, 0.5 mm on both sides of the width dimension, and 5 mm on both sides of the length dimension to facilitate wire cutting and clamping;

2) Milling machine processing: drilling and tapping screw holes;

3) Heat treatment processing;

4) Grinding machine processing: Grinding of six-sided square, accurate grinding of width and size;

5) Fast wire cutting process the I-groove standard and pull-tab; thickness grinding machine with remaining margin with height 1.2 mm;

6) Grinding machine processing: The external dimensions of the grinding machine are equipped with a thimble plate, and the height dimension is exactly 1mm.

Lock block processing

1) Prepare materials;

2) Grinding machine processing: Grinding on a six-sided square, the dimensions are accurate;

3) Wire cutting processing; fast wire molding;

4) Milling machine processing: drilling and tapping screw holes.

Ejector hole machining

The above Φ3 (including Φ3, Φ4, Φ5, Φ6) jack holes are processed with milling machine drilling and reaming; below Φ3 or non-standard jack holes, wire cutting is used to avoid the bottom.

Thimble machining

Φ2 and above thimble cutting machines leave a margin for the cutting length of the grinder, and the grinding machine processes the length and size of the grinding standard (the fitter processes it by itself); Flat thimbles and barrels are machined with a wire cutting length and a margin grinder; the grinder is used to grind the length and size accurately.
