Acrylic plate injection molding machine with automatic demolding function

Abstract

The invention provides an acrylic plate injection molding machine with an automatic demolding function, belongs to the technical field of acrylic plate production, and is used for solving the problems that an existing acrylic plate is slow in demolding after injection molding, and the production efficiency is reduced. Comprising a first frame, an adjusting support is arranged at the lower end of the first frame, a lower pressing plate is fixed to the first frame, a supporting rod is fixed to the side end of the first frame, a pressure hydraulic cylinder is fixed to the supporting rod, a second frame is fixed to the output end of the pressure hydraulic cylinder, an upper pressing plate is fixed to the second frame, and films cover the lower pressing plate and the upper pressing plate. The first frame and the second frame are each provided with a winding mechanism. According to the device, a formed acrylic plate is automatically demoulded, the demoulding speed is high, the safety is high, and the production efficiency is improved; liquid acrylic is convenient to pour, a new winding drum is convenient to replace, and the operation difficulty is reduced; the surface of the acrylic plate is uneven due to film wrinkles, the injection molding quality is guaranteed, meanwhile, the used film can be recycled, and waste is prevented.

Description

technical field [0001] The invention belongs to the technical field of acrylic plate production, and relates to an acrylic plate injection molding machine, in particular to an acrylic plate injection molding machine with an automatic demoulding function. Background technique [0002] Acrylic, also known as specially treated plexiglass, is a replacement product of plexiglass. The light box made of acrylic has good light transmission performance, pure color, rich color, beautiful and flat, taking into account both day and night effects, long service life, and does not affect use, etc. features. In addition, acrylic sheets can be perfectly combined with aluminum-plastic sheet profiles and advanced screen printing to meet the needs of merchants. Acrylic blister is the best form of outdoor advertising to improve the grade of business stores and unify the corporate image. Acrylic is a chemical material. In the application industry, acrylic raw materials generally appear in the fo...

Problems solved by technology

[0003] The acrylic sheet can be formed by injection molding. Generally, it is shaped by two glass plates and a spacer. A spacer is placed between the two glass plates to form a hollow layer. C-shaped clips are used to clamp the three sides of the two glass plates, and the other side is reserved for future use. Open the opening, and finally put the two clamped glass plates on the fixture, make the mold opening upward, fill the liquid acrylic into the mold, seal the mold opening, and the acrylic plate can be obtained after the liquid acrylic solidifies, but in the acrylic After the plate is formed, manual demoulding is required. When the two glass plates have a large area, it is difficult to demould, the work efficiency is low, and the glass plate and acrylic plate are easy to be damaged.
