Method for pultrusion of cabinet door panel using pultrusion die

Abstract

The invention discloses a pushing die head. The pushing die head comprises a die head body (2), an upper feeding plate (4), a lower feeding plate (5), a collecting plate (6) and feeding tracks (8), wherein the upper feeding plate (4) has an upper horizontal hole for upper layer glass fiber reinforced plastics raw material cloth (9) to pass through; the lower feeding plate (5) has a lower horizontal hole for lower layer glass fiber reinforced plastics raw material cloth (11) to pass through, the collecting plate (6) has a collecting horizontal hole for collecting the upper layer glass fiber reinforced plastics raw material cloth (9) and a foam filling plate (7), and the collecting plate (6) has a horizontal hole. The invention also discloses a method for pushing a cabinet door plate. The key point of the method lies in that the foam filling plate (7) is arranged between the two layers of glass fiber reinforced plastics raw material cloth and enters into the die head body (2). The pushing die head and the method provided by the invention have the advantages that the labour intensity is reduced, the manufacturing speed is accelerated, the manufacturing efficiency is improved, the operation step is reduced, the bonding strength between a glass fiber reinforced plastics outer plate and the foam filling plate (7) is enhanced, so that the bonding is firm, and the separation difficulty occurs.

Description

technical field [0001] The invention relates to a manufacturing equipment and method of cabinet parts in the field of network communication, in particular to a pultrusion die head and a method for pultruding the cabinet door panel by using the pultrusion die head. Background technique [0002] The cabinet can provide customers with comprehensive and complementary site equipment placement solutions. Because the cabinet has the characteristics of sub-compartment temperature control, it is objectively required that the door panel of the cabinet should have better heat insulation properties. The door panel of the traditional cabinet is a solid door panel of fiberglass material. The door panel is pultruded using a conventional pultrusion die. The traditional pultrusion die includes a die body with a heating device such as a heating wire, and the die body is penetrated with a pultrusion channel whose cross-sectional shape and size match the cross-sectional shape and size of the ...

Problems solved by technology

But this door panel also has defects: First, the manufacturing process is complicated, and it is necessary to bond six FRP outer panels to the front, rear, left, right, upper, lower, and six sides of the foam-filled panel. In this way, each door panel needs to manufacture six FRP outer panels and bond six First, there are many process steps, high labor intensity, slow speed, and low efficiency; secondly, the bonding effect between the FRP outer plate and the foam filled plate is not ideal, the bonding strength is small, not firm, and easy to detach
