What kind of steel is used for the thimble of the injection mold? What kind of material is generally selected for injection mold embryo


What is the steel used for the thimble of the injection mold

1. The thimble of the injection mold is H1SKD1SKD61. A Diethimble is a plastic mold accessory used in plastic molds. Thimble can also be called push rod, insert needle, needle, etc., sometimes the lathe is also called thimble.

2, 1 top rod column (K.O column) : used for ejecting the thimble and guide pin.

1 Small thimble plate: fixed guide pin. 1 Small thimble plate: fixed guide pin.

1 Thimble: ejecting the material belt to separate the material belt from the mold. 1 External pull rod: used to open the cavity and limit the opening distance of the cavity. 1 Heating rod: heat up the mold.

3, plastic mold thimble, used in plastic mold. Thimble can also be called push rod, insert needle, needle, bracket needle, etc., and the mold thimble is easy to break, not durable, to avoid the occurrence of these problems. Pay attention to the following points during the design or use of the thimble, you can make the production twice the result with half the effort, and the work efficiency can be guaranteed.

4, commonly used plastic thimble materials include the following: steel: such as ordinary carbon structural steel, hardened steel, high-speed steel, etc., with high hardness, good wear resistance and other characteristics, suitable for injection parts in the need for high strength and high hardness parts.

Second, what kind of material is the injection mold embryo generally selected

1, the general selection of carbon mold steel: mainly the use of carbon structural steel, representative steel number S45C, S48C, S50C, S55C and so on. Pre-hardened die steel: mainly the medium carbon alloy steel with higher hardenability is used, representing the steel number P20.

2, in the choice of a set of mold mold material, first of all we need to determine whether the mold is out of the original body, if not the original body and the load is not large, you can choose yellow card (or **) steel to do the mold embryo (and mold products do not contain corrosive gases). Yellow card (or **) is the Hong Kong name for medium carbon Steel, translated from English (YellowLabel Tool Steel).

3, the mold frame? Kind? What material? Kind? Zinco - Specific models: H13, SKD61, DAC, DAC55, 2344,840 to undergo heat treatment, otherwise there is no way to directly use? .

4, the general selection of carbon mold steel: mainly the use of carbon structural steel, representative steel number S45C, S48C, S50C, S55C, etc. Pre-hardened die steel: mainly the medium carbon alloy steel with higher hardenability is used, representing the steel number P20.

5, so the selected steel should have good heat treatment performance, but also have good cutting performance in the state of high hardness. Commonly used mold materials: Here I only introduce the imported materials commonly used by plastic mold manufacturers in the Pearl River Delta region of Guangdong.

6, the highly corrosive plastic is generally selected S136, 2316,420 and other mold steel, weakly corrosive can choose S136, 2316,420, SKD61, NAK80, PAK90, 718 and so on.
