Description

Mold pressing die capable of interchanging inserts to produce multi-specification air duct splicing plate products

Technical Field

The utility model relates to a compression mold technical field especially relates to a compression mold of many specifications dryer splice plate products of interchangeable mold insert production.

Background

Conventional compression molds, generally a set of molds, produce only one or two sizes of product. Because the product specification kind of one set of mould production is more, and the mould is when producing the product, and each die cavity receives pressure easy unbalance more, compares the single mould of product specification, and the deckle edge is not different easily appears in the mould of many specifications product, and thickness is not guaranteed scheduling problem well. Therefore, for products with small size, a set of dies is often used to produce a plurality of products with the same specification, namely, a so-called "1 × N" mode, which means that the set of dies only produces one product, and one set of dies can produce N products.

If the product specification is more than ten and the product size is more than 1 meter, so that one set of die is expected to produce two specifications of products simultaneously, namely the mode of 1+1 represents that the set of die can produce two products, one die can produce 1A and 1B, and the corresponding die size is very large. The bigger the die is, the higher the processing cost of the die is, the bigger the press machine is required for production, and the discharging and product demoulding during production are not facilitated. However, if a set of mold is required for each product size, the mold cost is very high.

The splicing plates of the cooling tower SMC (mould pressing) air duct are taken as an example, the cooling tower SMC (mould pressing) air duct is a novel glass fiber reinforced plastic mould pressing air duct and is divided into an upper part and a lower part, and each part can be divided into a plurality of equal parts of splicing plates which are connected by bolts and are assembled and formed. The cooling tower SMC (mould pressing) air cylinders with different specifications are different in height and diameter, and the sizes of the splicing plates and the edge bending radians of the splicing parts are different, so that the cooling tower SMC (mould pressing) air cylinders with different specifications are spliced. The height of a cooling tower SMC (mould pressing) air duct is over 1 meter generally, if the production is carried out in a 1 XN mode of small-size products, the mould cost is very high, and a novel mould pressing mould suitable for producing splicing plates with different specifications is needed.
