Description

Injection molding refers to heating and melting plastic raw materials, cooling and molding into automotive parts through a gating system. Since the heating and pressing device can work in stages, our Injection Molds Plastic Injection Molding can not only help you make plastic parts with complex shapes, but also have high production efficiency and good quality, so they play a great role in the molding of plastic parts.

Features

Our Injection Molds Plastic Injection Molding can quickly and accurately shape molten plastic into a fixed shape, they are usually designed with multiple cavities connected to the runner, so that many products can be produced in one shot, which can effectively improve work efficiency. Moreover, they can strictly control product quality, have good accuracy, and can quickly produce parts with small errors and high precision.

1.Classification according to process properties

a.Blanking die: a die that separates materials along a closed or open contour. Such as blanking die, punching die, cutting die, cutting die, trimming die, cutting die, etc.

b.Bending die: a die for bending and deforming a blank or other blank along a straight line (bending curve), so as to obtain a workpiece with a certain angle and shape.

c.Drawing die: it is a die that makes the blank into open hollow parts, or further changes the shape and size of hollow parts.

d. Forming die: it is a die that directly copies and forms the blank or semi-finished workpiece according to the shape of the convex and concave die in the drawing, while the material itself only produces local plastic deformation. Such as bulging die, necking die, expanding die, undulating forming die, flanging die, shaping die and etc.

2.Classification according to process combination degree

a.Single process Die: a die that completes only one stamping process in one stroke of the press.

b.Compound die: a die that has only one station and completes two or more stamping processes at the same station at the same time in one stroke of the press.

c.Progressive die (also known as continuous die): a die with two or more stations in the feeding direction of the blank. In one stroke of the press, two or more stamping processes are completed successively at different stations.

3.Classification according to the processing method of products

According to different product processing methods, molds can be divided into five categories: punching and shearing molds, bending molds, drawing molds, forming molds and compression molds.

a.Punching and shearing die: the work is completed by shearing. The common forms include cutting die, blanking die, punching die, trimming die, edge forming die, broaching die and punching and cutting die.

b.Bending die: it is to bend the flat wool into an angular shape. Depending on the shape, accuracy and production capacity of the parts, there are many different forms of dies, such as ordinary bending die, cam bending die, crimping die, circular arc bending die, bending punching die and twisting die.

c.Drawing mould: the drawing mould is to make the flat rough embryo into a bottomed seamless container.

d.Forming die: it refers to changing the shape of wool embryo by various local deformation methods. Its forms include convex forming die, crimping forming die, necking forming die, hole flange forming die and round edge forming die.

e.Compression die: it uses strong pressure to make the metal rough embryo flow and deform into the required shape. Its types include extrusion die, embossing die, embossing die and end pressing die.

Taking Huoluo mould as an example:

1:Casting or forging the blank according to the tire die drawing, then rough turning the blank and heat treatment. The tire die blank shall be fully annealed to eliminate internal stress. It shall be leveled during annealing to avoid excessive deformation.

2:Drill the lifting hole according to the drawing, then process the outer diameter and height of the pattern ring in place according to the semi finishing drawing, turn the inner cavity of the pattern ring with the semi finishing procedure, and use the semi finishing sample plate for inspection after turning.

3:Use the processed tire mold pattern electrode to form the pattern in the pattern ring by EDM, and use the sample plate for inspection.

4:Divide the pattern ring into several parts according to the manufacturer's requirements, draw the marking lines respectively, put it into the tooling, punch the back waist hole and tap.

5:According to the equal parts divided in procedure 8, align and cut at the scribed line.

6:The cut pattern blocks shall be polished, angle cleaned, root cleaned and exhaust holes shall be drilled according to the requirements of the drawing.

7:Sand shall be sprayed evenly inside the cavity of the pattern block, and the color shall be consistent.

8:Combine and assemble the tread ring, die sleeve and upper and lower side plates to complete the tire die.
