DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0018] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present invention should be understood by people with ordinary skills in the field to which the present invention belongs.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, a composite material shaping machine is used in a closed and constant temperature and humidity space. The closed space with constant temperature and humidity can be achieved by an air conditioning control system and a humidifier. It belongs to the existing conventional technology, including a constant temperature frame 1, and a load plate 2 with a through hole is fixedly connected to the top of the constant temperature frame 1. A heater (shown in the figure and a temperature controller not shown in the figure) is arranged in the constant temperature frame 1. The temperature of the surface around the load plate 2 can be controlled by the cooperation of the heater and the temperature controller, so that in the process of pressing the composite material, the temperature is in an appropriate state. A frame 3 is fixedly connected to the load plate 2, and a plurality of mold lower plates 4 are arranged on the load plate 2. A pressure part 7 is arranged on the frame 3, and a placement groove 5 is opened on the mold lower plate 4. A pusher part 6 is slidably arranged in the placement groove 5. When the composite material is stacked on the lower template 4, the composite material can be pressed and formed under the pressure of the pressure part 7. The pusher part 6 can push the pressed and formed product to move, so that the pressed and formed product is separated from the mold lower plate 4.

[0020] Under the pressure of the pressure-applying part 7, the composite material can be pressed into shape (fitting the shape of the lower plate of the mold), and then by toggling the pushing part 6, the pressed product can be pushed to move, so that the pressed product is separated from the lower plate 4 of the mold, and the pressed product can be simply and quickly removed, which is convenient for subsequent operations and provides convenience for subsequent processing of the comfortable surface on the pressed product (the circumference of the bulletproof chest plate and the human body fitting surface are covered with EVA resin material and wrapped with polyester cloth on the outside).

[0021] In a preferred embodiment of the present utility model, the pressing part 7 includes a cylinder 71 fixedly installed on the frame 3. A hole is provided on the frame 3 for the output end of the cylinder 71 to penetrate, so that the output end of the cylinder 71 extends into the frame 3. The output end of the cylinder 71 is fixedly connected with a mold upper pressing plate 72 adapted to the mold lower plate 4. In this application, the mold cavity formed by the mold upper pressing plate 72 and the mold lower plate 4 conforms to the mechanical structure of the human chest cavity, which is convenient for covering the inner surface of the pressed product with EVA resin material and wrapping the outer surface with polyester cloth, so as to make a bulletproof chest insert plate. A pressure sensor 73 is fixedly installed between the mold lower plate 4 and the load plate 2. A control switch 74 is installed on the frame 3, and the control switch 74 is electrically connected to the pressure sensor 73 and the cylinder 71. The control switch 74 is electrically connected to the pressure sensor 73 and the cylinder 71 to realize the control of the cylinder 71 through pressure changes. This is a common configuration of an automatic control system, which is widely used in automatic machinery, pneumatic control systems, hydraulic systems, and other applications that require precise pressure control. Through this configuration, precise control of the movement of the cylinder 71 can be achieved, improving efficiency and safety.

[0022] Place the composite material on the mold lower plate 4, and then start the cylinder 71 through the control switch 74. The cylinder 71 pushes the mold upper pressing plate 72 downward. During the process of the mold upper pressing plate 72 and the mold lower plate 4 closing the mold, the composite material can be pressed into shape. And during the process of the cylinder 71 pushing the mold upper pressing plate 72 to close the mold with the mold lower plate 4, the control switch 74 will continuously adjust according to the pressure signal fed back by the pressure sensor 73, and can precisely control the movement of the cylinder 71.

[0023] In another preferred embodiment of the present utility model, the material pushing part 6 includes a material pushing plate 61. The material pushing plate 61 is slidably arranged in the placing groove 5, and the surface of the material pushing plate 61 is adapted to the surface of the mold lower plate 4, so that the arranged material pushing plate 61 will not interfere with normal pressing.

[0024] In still another preferred embodiment of the present utility model, a notch is provided on the material pushing plate 61. A spring 62 is placed in the notch. The top end of the spring 62 is connected to the inner wall of the notch, the bottom end of the spring 62 is connected to the inner wall of the placing groove 5, and a slider 64 is fixedly connected to the material pushing plate 61. A chute adapted to the slider 64 is provided on the inner wall of the placing groove 5.

[0025] After the composite material is pressed and formed on the lower die plate 4, it overcomes the elastic force of the spring 62 to push the ejector plate 61 upward. The chute and the slider 64 limit the movement track of the ejector plate 61, preventing the ejector plate 61 from moving upward excessively and detaching from the placement groove 5. When the ejector plate 61 moves upward, it will push the pressed product upward, causing the product to separate from the lower die plate 4. Subsequently, under the action of the restoring force of the spring 62, the ejector plate 61 can be driven to move downward into the placement groove, preventing the product from sticking to the lower die plate 4. This enables the pressed product to be removed simply and quickly, facilitating subsequent operations. It provides convenience for processing a comfortable surface on the pressed product later (the surface of the bulletproof chest insert that fits the human body is covered with EVA resin material and wrapped with polyester cloth on the outside).

[0026] It should be noted that both sides of the ejector plate 61 are fixedly connected with a lever 63. By using the lever 63, the ejector plate 61 can be pushed to move, so as to separate the pressed product from the lower die plate 4. The lever 63 makes it more convenient and rapid to push the ejector plate 61.

[0027] Those of ordinary skill in the art should understand that the discussion of any embodiment above is only exemplary and is not intended to imply that the scope of the present invention is limited to these examples; under the concept of the present invention, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order. There are many other variations in different aspects of the present invention as described above, and they are not provided in detail for the sake of brevity.

[0028] The embodiments of the present invention are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
