[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1: Figures 1-4 As shown, the 3D molding and pressing fixture for fiberglass boards includes a base 100, a die 101, two movable plates 102, a fixed frame 103, a mounting frame 104, a pressing mechanism 110, multiple elastic support mechanisms 120, a lifting mechanism 130, a transmission mechanism 140, and two blowing mechanisms 150.

[0033] A die 101 is mounted on a base 100. Two through slots are formed on the bottom surface of the die 101, and a heating plate is installed inside the die 101. Two movable plates 102 are slidably connected to the two through slots respectively. A fixed frame 103 is fixedly connected to the base 100 and the die 101. A mounting frame 104 is mounted on the side of the die 101. A pressing mechanism 110 is mounted on the fixed frame 103. Multiple elastic support mechanisms 120 are used to support the two movable plates 102. A lifting mechanism 130 is used to move the two movable plates 102 back and forth up and down. Two air blowing mechanisms 150 are mounted on the mounting frame 104, and the air blowing mechanisms 150 are used to blow air into the product formed inside the die 101.

[0034] Specifically, by combining the molding mechanism 110 and the die 101, and then injecting raw material into the molding mechanism 110 and the die 101, when the raw material is formed into a product, the molding mechanism 110 and the die 101 are separated; then the lifting mechanism 130 lifts the two movable plates 102, thereby lifting the product in the die 101, which facilitates the separation of the product from the die 101; then the blower mechanism 150 is activated to blow air towards the product, which accelerates the cooling speed of the product and thus speeds up the production efficiency of the product.

[0035] like Figure 1 and Figure 2 As shown, the molding mechanism 110 includes a hydraulic cylinder 111 and a punch 112. The hydraulic cylinder 111 is mounted on the inner top surface of the fixed frame 103; the punch 112 is mounted on the extension end of the hydraulic cylinder 111, and the punch 112 matches the die 101. A heating plate is installed inside the punch 112.

[0036] Specifically, by placing the three-dimensional customized preform into the cavity mold 101, and then activating the hydraulic cylinder 111, the extension end of the hydraulic cylinder 111 drives the punch 112 to move downward, thereby inserting the punch 112 into the cavity mold 101, so that the punch 112 and the cavity mold 101 cooperate to mold the three-dimensional customized preform, thereby obtaining the product (i.e., the fiberglass mobile phone battery protection board).

[0037] like Figure 4 and Figure 5 As shown, the elastic support mechanism 120 includes a telescopic rod 121 and a support spring 122. The telescopic rod 121 is mounted on the base 100, and the extended end of the telescopic rod 121 is fixedly connected to the bottom surface of the movable plate 102; the support spring 122 is mounted on the base 100, and the upper end of the support spring 122 is fixedly connected to the bottom surface of the movable plate 102.

[0038] Specifically, by setting up the telescopic rod 121 and the support spring 122, under normal conditions, the support spring 122 can support the movable plate 102 and the product located above the movable plate 102. If the movable plate 102 is moved upward, the support spring 122 will be stretched, but when the force of moving the movable plate 102 upward disappears, the rebound force of the support spring 122 will pull the movable plate 102 downward.

[0039] like Figure 4-Figure 6 As shown, the lifting mechanism 130 includes a motor 131, two reciprocating lead screws 132, two reciprocating lead screw nuts 133, two moving seats 134, a rotating rod 135, two gears 136, two first cams 137, two racks 138, and two large bevel gears 139.

[0040] The motor 131 is mounted on the bottom surface of the die 101; two reciprocating screws 132 are rotatably connected to the bottom surface of the die 101, and one end of any one reciprocating screw 132 is fixedly connected to the power output shaft of the motor 131; two reciprocating screw nuts 133 are respectively sleeved on the two reciprocating screws 132; two movable seats 134 are respectively fixedly sleeved on the two reciprocating screw nuts 133; a rotating rod 135 is rotatably connected to the two movable seats 134; two first cams 137 are respectively fixedly sleeved on the rotating rod 135, and the two first cams 137 respectively contact the bottom surfaces of the two movable plates 102. Two gears 136 are respectively fixedly sleeved on the rotating rod 135; two racks 138 are mounted on the top surface of the base 100, and the two racks 138 are respectively meshed with the two gears 136; two large bevel gears 139 are respectively mounted on the two rotating rods 135.

[0041] Specifically, when the two reciprocating screws 132 rotate simultaneously, the two reciprocating screw nuts 133 will move simultaneously, thereby driving the two moving seats 134 to move, which in turn drives the rotating rod 135 to move horizontally. Since the gear 136 on the rotating rod 135 meshes with the rack 138, when the rotating rod 135 moves horizontally, under the influence of the gear 136 and the rack 138, the rotating rod 135 will rotate, thereby driving the two first cams 137 to rotate. The rotating first cams 137 will push the movable plate 102 upward, and with the cooperation of the rotating first cams 137 and the support spring 122, the movable plate 102 will move up and down back and forth, thereby facilitating the separation of the product on the movable plate 102 from the die 101.

[0042] like Figure 6 and Figure 7 As shown, the transmission mechanism 140 includes a crossbar 141, two small bevel gears 142, two first bevel gears 143, and a second cam 144.

[0043] The crossbar 141 is rotatably connected to the side of the die 101; two small bevel gears 142 are fixedly sleeved on the crossbar 141, and the two small bevel gears 142 are respectively meshed with two large bevel gears 139; two first bevel gears 143 are respectively fixedly sleeved on the crossbar 141; and the second cam 144 is fixedly sleeved on the crossbar 141.

[0044] Specifically, when any reciprocating screw 132 rotates, it will drive the crossbar 141 to rotate through the large bevel gear 139 and the small bevel gear 142, and drive the other reciprocating screw 132 to rotate through another small bevel gear 142 and the large bevel gear 139. Simply put, when any reciprocating screw 132 rotates, under the influence of the crossbar 141, the small bevel gear 142 and the large bevel gear 139, the other reciprocating screw 132 will also rotate synchronously.

[0045] Furthermore, since the crossbar 141 is connected to the reciprocating screw 132 through the small bevel gear 142 and the large bevel gear 139, the rotation speed of the crossbar 141 is significantly faster than the rotation speed of the reciprocating screw 132.

[0046] like Figure 7 and Figure 8 As shown, the blower mechanism 150 includes a fixed cylinder 151, an air outlet pipe 152, a horizontal plate 153, a rotating shaft 154, a blower fan blade 155, and a second bevel gear 156. The fixed cylinder 151 is fixedly connected to the mounting bracket 104, and the bottom of the fixed cylinder 151 is open; the air outlet pipe 152 is installed on the top of the fixed cylinder 151; the horizontal plate 153 is installed inside the fixed cylinder 151; the rotating shaft 154 is rotatably installed on the horizontal plate 153; the blower fan blade 155 is installed on the rotating shaft 154; the second bevel gear 156 is installed at the lower end of the rotating shaft 154, and the second bevel gear 156 meshes with the first bevel gear 143.

[0047] Specifically, when the crossbar 141 rotates, it drives the first bevel gear 143 to rotate, which in turn drives the second bevel gear 156 to rotate, which in turn drives the rotating shaft 154 to rotate, which in turn drives the fan blades 155 to rotate. The rotating fan blades 155 deliver air into the air outlet pipe 152, and then blow the air through the air outlet pipe 152 onto the product located in the cavity mold 101, thereby accelerating the cooling speed of the product.

[0048] like Figure 7 As shown, the 3D molding and pressing fiberglass board fixture also includes a spraying mechanism 160, which includes a water tank 161, a piston cylinder 162, a push plate 163, a telescopic spring 164, a liquid extraction pipe 165, a liquid outlet pipe 166, and an atomizing nozzle 167.

[0049] Water tank 161 is fixedly connected to base 100; piston cylinder 162 is mounted on mounting bracket 104, piston plate is slidably connected inside piston cylinder 162, piston rod is mounted on piston plate, piston rod passes through piston cylinder 162 and is slidably connected to piston cylinder 162. Push plate 163 is fixedly connected to the lower end of piston rod; one end of telescopic spring 164 is fixedly connected to push plate 163, and the other end of telescopic spring 164 is fixedly connected to piston cylinder 162.

[0050] One end of the suction pipe 165 is fixedly connected to the piston cylinder 162, and the other end of the suction pipe 165 is fixedly connected to the water tank 161; the discharge pipe 166 is installed on the piston cylinder 162; and the atomizing nozzle 167 is installed on the discharge pipe 166. Both the suction pipe 165 and the discharge pipe 166 are equipped with one-way valves, ensuring that water in the water tank 161 can only enter the piston cylinder 162 through the suction pipe 165, and that water in the piston cylinder 162 can only enter the atomizing nozzle 167 through the discharge pipe 166.

[0051] Specifically, when the second cam 144 rotates, it pushes the push plate 163 to move, which in turn drives the piston rod and piston plate to move. With the cooperation of the rotating second cam 144 and the telescopic spring 164, the push plate 163 moves up and down repeatedly, which in turn drives the piston rod and piston plate to move up and down repeatedly, thereby drawing water from the water tank 161 into the piston cylinder 162 and delivering the water in the piston cylinder 162 to the atomizing nozzle 167, so that the water is sprayed onto the product located in the concave mold 101 in the form of water mist, thereby accelerating the cooling speed of the product.

[0052] Working principle: In actual use, the three-dimensional customized preform is placed into the cavity mold 101, and then the hydraulic cylinder 111 is activated, causing the extension end of the hydraulic cylinder 111 to drive the punch 112 to move downward, thereby inserting the punch 112 into the cavity mold 101. The punch 112 and the cavity mold 101 cooperate to mold the three-dimensional customized preform. At the same time, the heating plates in the punch 112 and the cavity mold 101 are activated to heat the punch 112 and the cavity mold 101, thereby heating the three-dimensional customized preform.

[0053] After holding the pressure for a certain period of time, the product (i.e., the fiberglass mobile phone battery protection board) is obtained. Then, by activating the hydraulic cylinder 111, the extension end of the hydraulic cylinder 111 drives the punch 112 to move upward, thereby separating the punch 112 from the die 101 and the product.

[0054] Then, by starting the motor 131, the power output shaft of the motor 131 drives a reciprocating screw 132 to rotate, which in turn drives the large bevel gear 139 to rotate, which in turn drives the crossbar 141 to rotate through the small bevel gear 142. When the crossbar 141 rotates, it will drive another reciprocating screw 132 to rotate through another small bevel gear 142 and the large bevel gear 139, so that the two reciprocating screws 132 rotate synchronously.

[0055] When the two reciprocating screw nuts 133 rotate simultaneously, they will move simultaneously, thereby driving the two moving seats 134 to move, which in turn drives the rotating rod 135 to move horizontally. Since the gear 136 on the rotating rod 135 meshes with the rack 138, when the rotating rod 135 moves horizontally, it will rotate under the influence of the gear 136 and the rack 138, thereby driving the two first cams 137 to rotate. The rotating first cams 137 will push the movable plate 102 upward, and with the cooperation of the rotating first cams 137 and the support spring 122, the movable plate 102 will move up and down back and forth, which makes it easier to separate the product on the movable plate 102 from the die 101, thus making it easier to remove the product.

[0056] Furthermore, when the crossbar 141 rotates, it will drive the first bevel gear 143 to rotate, which in turn drives the second bevel gear 156 to rotate, which in turn drives the rotating shaft 154 to rotate, which in turn drives the fan blade 155 to rotate. The rotating fan blade 155 will deliver air into the air outlet pipe 152, and then blow the air to the product located in the cavity mold 101 through the air outlet pipe 152, thereby accelerating the cooling speed of the product.

[0057] Furthermore, when the crossbar 141 rotates, it will also drive the second cam 144 to rotate. The rotating second cam 144 will push the push plate 163 to move, and in cooperation with the telescopic spring 164, the push plate 163 will move up and down repeatedly, thereby driving the piston rod and piston plate to move up and down repeatedly, thereby drawing water from the water tank 161 into the piston cylinder 162, and delivering the water in the piston cylinder 162 to the atomizing nozzle 167, thereby spraying the water in the form of water mist onto the product located in the concave mold 101, thereby further accelerating the cooling speed of the product.

[0058] Once the product temperature drops to a suitable level (which can be manually set), remove the product located above the movable plate 102.

[0059] Example 2: As Figures 1-8 As shown, the working method of the 3D molding and pressing fiberglass board fixture includes the following steps:

[0060] Step 1: Place the 3D customized preform into the cavity mold 101, ensuring accurate positioning;

[0061] Step 2: Start the hydraulic cylinder 111, so that its extension end drives the punch 112 to move downward, cooperate with the die 101 to mold the preform, and at the same time start the heating plate in the die 101 and the punch 112 to heat the preform to promote molding.

[0062] Step 3: Maintain pressure for a certain period of time until the raw material solidifies to obtain the desired product;

[0063] Step 4: Start the hydraulic cylinder 111 to raise the punch 112, then start the motor 131. The power output shaft of the motor 131 drives a reciprocating screw 132 to rotate, which in turn drives the large bevel gear 139 to rotate. This, in turn, drives the crossbar 141 to rotate via the small bevel gear 142. When the crossbar 141 rotates, it drives another reciprocating screw 132 to rotate via another small bevel gear 142 and the large bevel gear 139. This causes the two reciprocating screws 132 to rotate synchronously. When the two reciprocating screw nuts 133 rotate simultaneously, they will move simultaneously, thereby driving... The two movable seats 134 move, which in turn drives the rotating rod 135 to move horizontally. Since the gear 136 on the rotating rod 135 meshes with the rack 138, when the rotating rod 135 moves horizontally, it will rotate under the influence of the gear 136 and the rack 138, which will drive the two first cams 137 to rotate. The rotating first cams 137 will push the movable plate 102 upward, and with the cooperation of the rotating first cams 137 and the support spring 122, the movable plate 102 will move up and down back and forth, which will facilitate the separation of the product on the movable plate 102 from the die 101.

[0064] Step 5: Activate the blower mechanism 150 and the spray mechanism 160 to blow air and spray water mist towards the product to accelerate the cooling speed of the product.

[0065] Step 6: After the product has cooled to the preset temperature, remove the product located above the movable plate 102.
