The Features of Low Melting Point Alloy Mold

The low melting point alloy mold is formed by solidifying the low melting point liquid alloy in the sample. New technology and new technology. The convex and concave die and the blank holder of the low melting point alloy mold take the sample as the parting surface, and the gap between the convex and concave die is uniform and is the thickness of the sample. After the convex and concave die and the blank holder are solidified and formed, only need It can be used after proper grinding. The low melting point alloy mold has the following characteristics in the production process:
(1) The molding cycle is short.
Since the low melting point alloy mold is formed by melting and solidification, it saves a lot of man-hours due to machining, and also saves the research and gap adjustment of the convex and concave molds. It only takes 12 days from the production of the sample to the mold pressing. In comparison, it can save 90% of time.
(2) The molding process is simple.
The low melting point alloy mold is made by making a sample, and its mold surface is cast at one time without machining, especially for some complex and large molds, no machining equipment is used, and the molding process is greatly simplified, thereby reducing the cost of production. Difficulty in mold making.
(3) The molding cost is low.
Low melting point alloy molds are generally not used as permanent molds. For some parts with small batches, they can be melted and made into other molds after production. This alloy can be used repeatedly, which greatly reduces the cost of molds. Samples can be It can be made by knocking with steel plate or pasted with glass cloth, or even made of paper pulp and then coated with high temperature resistant glue.
(4) It is beneficial to the stamping process test.
For stamping and forming parts, the shapes of the products are different. From the aspect of stamping technology to the springback of bending parts, it is difficult to use steel molds and casting molds to ensure a successful one-time success. Molds made of low melting point alloys can meet this process requirement. , it is possible to continuously correct the sample until it finally meets the technological requirements of the part, while the correction of the steel mold and the casting mold is more difficult.
(5) Suitable for small batch production.
The gap of the low melting point alloy mold is relatively uniform, so that the size and accuracy of the parts can be easily guaranteed, which is more convenient for parts with complex structures and small batches.
(6) The mold storage space is small.
After a pair of molds are used, they can be melted and cast into new molds, and only the samples can be stored, so the storage space is small.
