Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing.

[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0023] Such as figure 1 As shown, inject the resin system into the metal mold cavity through the metering pump, infiltrate the reinforcing material (fiber system), and then close the mold and lock it, and put the prepared resin glue at 15°C-35°C and 0.05-0.25MPa Under pressure, inject the mold cavity from the injection hole to soak the glass fiber reinforced material; finally, after temperature-controlled curing by the heating device...

Abstract

The invention discloses a molding technology for a composite material product. The molding technology comprises the following steps of: (1) placing a glass fiber reinforcement material in a mold cavity of a metal mold in advance; (2) after closing the mold and locking, injecting prepared resin adhesive liquid into the mold cavity from an injection hole at a certain temperature and pressure, and soaking the glass fiber reinforcement material; and (3) carrying out temperature control solidification through a heating device in the metal mold, opening the mold and demolding. The molding technology for the composite material product, disclosed by the invention, can effectively solve the problem of incapability of rapid solidification existing in the mold scheme for composite material product and mold materials in the prior art, and the molding technology is low in production cost and is beneficial to popularization.

Description

technical field [0001] The invention relates to a mold forming process scheme for composite material products, and specifically provides a process for setting a heating device to maintain a specific temperature in a specific alloy mold and using temperature control technology to control the curing of composite material products. Background technique [0002] The traditional composite product molding process is to inject resin glue into the mold cavity. Under the action of pressure, the resin glue flows in the reinforced material preform and transfers to various parts, filling the mold cavity and draining the mold through glue flow. The air bubbles in the cavity are then solidified to make the product in the molding process. [0003] Composite product molding process is a technology suitable for medium batch production between hand lay-up process and SMC process. Because the process is relatively young, there are inevitably some technical difficulties and problems to be furt...
