The creation is a direct-moving side heat-type pressure forming device, in particular, a hot-pressing thin-shell composite material forming technology.

Composite materials generally consist of two or more materials, which can be divided into reinforcing materials and substrates. The structural strength is mainly derived from reinforcing materials such as glass fibers and carbon fibers. The substrate provides a structural structure for bonding reinforcing materials such as epoxy or phenolic resins. Compared with general materials, composite materials have anisotropic properties and can produce different structural characteristics according to different application requirements. Generally, the conventional hot-pressed composite material manufacturing method, the most commonly used methods are autoclave, vacuum/pressure bag, resin transfer or hot press hot press forming, etc., but the hot pressing temperature of the above method is generally below 300 ° C, Moreover, the thermosetting resin is often used as a substrate for heat curing, and cannot be used for hot press forming of a thermoplastic pitch-based carbon/carbon composite material. Although there is a hot press forming method for raising the heating temperature by external heating, it is limited to The specific shape of the upper mold and the lower mold can be hot-pressed, and the autoclave equipment is expensive and the temperature is not high.

Guide means can be arranged on the moving piece and the side shifting movable member to ensure that the straight moving movement of the straight moving movable member can be converted into the lateral movement of the side moving movable member, and the heat resistant elastic material is located between the side moving movable member and the blank material. In order to generate a pressure-like state and apply pressure to the billet, the heating member provides the temperature required for hot pressing, and can be directly disposed around the outer wall of the fixing member, so that the heat is uniformly transmitted radially inward, thereby achieving mass production and reducing the manufacturing cost. .

The purpose of the present invention is to provide a manufacturing apparatus capable of forming a composite material at a high temperature and heat-like pressure, and is not limited by the hot press forming temperature of 300 ° C or less. The utility model is characterized in that a straight moving member is used for straight movement, and a side moving movable member is converted into a side movement for direct movement, and then a side movement is applied to the heat resistant elastic material, and finally, the heat resistant elastic material is used to transmit the force. The blank on the fixing member forms a pressure-like state, and the blank is formed by compression.

Since this creation is a thermal type pressure forming device, it is not necessary to precisely match the mold design, and the composite material can be hot-pressed in a simple manner, and the external heating method can be used to increase the hot pressing temperature, and the cheap and simple mold design device can be used.
