A high-efficiency demoulding injection mold

Abstract

The invention belongs to the technical field of die manufacturing, in particular to an efficient demolding injection mold. The efficient demolding injection mold comprises a top plate, a bottom plate,a supporting plate, a backing plate and a die assembling unit. The die assembling unit is mounted between the top plate and the bottom plate and comprises an upper die, a lower die, an air cylinder,a push plate and an ejector rod; the ejector rod is mounted on the bottom plate, the end part of the ejector rod stretches to the top end of the lower die and is aligned to the top end of the lower die, and the end part of the ejector rod is provided with a sealing block through a sealing strip. By matching the top plate, the bottom plate, the supporting plate and the die assembling unit, a condition of stagnation in a demolding process is avoided, the stability of the ejector rod in a blank ejecting process is enhanced, and a condition that demolding is affected as a disc blank or a cylindrical blank, the diameters of two ends of which are different greatly, incline or roll over in the ejected process to be locked in the lower die is prevented.

Description

Technical field [0001] The invention belongs to the technical field of mold manufacturing, and specifically is an injection mold with high efficiency demolding. Background technique [0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automatic operation, a variety of colors, and shapes that can range from simple to complex. The size can be from large to small, and the size of the product is accurate, the product is easy to update, and it can be formed into a complex shape part. Injection molding is suitable for mass production and complex shape products. At a certain temperature, it is completely melted by screw stirring Plastic materials are injected into the mold cavity with high pressure and cooled and solidified to obtain molded products; this method is suitable for the mass production of parts with complex shapes and is one of the ...

Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology and solve the difficulty of demoulding, when processing a disc-shaped or cylindrical product with a large difference in diameter at both ends, it is very easy to cause the product to tilt during demoulding, or even The situation of overturning, thus seriously affecting the overall work efficiency in the injection molding process; the present invention proposes an injection mold with high efficiency demoulding
