DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0032] Example 1: Figure 1-Figure 4 As shown, the 3D molding fiberglass board jig includes a base 100, a die 101, two movable plates 102, a fixing frame 103, a mounting frame 104, a molding mechanism 110, a plurality of elastic supporting mechanisms 120, a lifting mechanism 130, a transmission mechanism 140 and two blower mechanisms 150.

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

[0034] Specifically, the die pressing mechanism 110 and the die 101 are combined together, and then raw materials are injected into the die pressing mechanism 110 and the die 101. When the raw materials are formed into products, the die pressing mechanism 110 and the die 101 are separated; the two movable plates 102 are lifted up by the lifting mechanism 130, and then the product in the die 101 is lifted up, so as to facilitate the separation of the product from the die 101; and the air blowing mechanism 150 is started to blow air in the direction of the product, so as to speed up the cooling speed of the product, thereby speeding up the production efficiency of the product.

[0035] like Figure 1 and Figure 2 As shown, the die pressing 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 extended end of the hydraulic cylinder 111, the punch 112 matches the die 101, and a heating plate is installed inside the punch 112.

[0036] Specifically, the three-dimensional customized preform is placed into the die 101, and then the hydraulic cylinder 111 is started so that the extended end of the hydraulic cylinder 111 drives the punch 112 to move downward, and then the punch 112 is inserted into the die 101, so that the punch 112 cooperates with the die 101 to mold the three-dimensional customized preform, thereby obtaining a product (i.e., a glass fiber mobile phone battery protection plate).

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

[0041] Specifically, when the two reciprocating screws 132 rotate at the same time, the two reciprocating screw nuts 133 will move at the same time, thereby driving the two moving seats 134 to move, and then driving the rotating rod 135 to move horizontally. Since the gear 136 on the rotating rod 135 is engaged 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 cam 137 will lift the movable plate 102 upward, and with the cooperation of the rotating first cam 137 and the support spring 122, the movable plate 102 will move back and forth up and down, 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 cross bar 141 is rotationally connected to the side of the die 101; two small bevel gears 142 are fixedly sleeved on the cross bar 141, and the two small bevel gears 142 are respectively meshed with the two large bevel gears 139; the two first bevel gears 143 are respectively fixedly sleeved on the cross bar 141; the second cam 144 is fixedly sleeved on the cross bar 141.

[0044] Specifically, when any reciprocating screw 132 rotates, the cross bar 141 will be driven to rotate through the large bevel gear 139 and the small bevel gear 142, and the other reciprocating screw 132 will be driven to rotate through the other small bevel gear 142 and the large bevel gear 139. In simple terms, when any reciprocating screw 132 rotates, under the influence of the cross bar 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 cross bar 141 is connected to the reciprocating screw 132 via the small bevel gear 142 and the large bevel gear 139 , the rotation speed of the cross bar 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 blade 155 and a second bevel gear 156. The fixed cylinder 151 is fixedly connected to the mounting frame 104, and the bottom of the fixed cylinder 151 is open; the air outlet pipe 152 is installed at the top of the fixed cylinder 151; the horizontal plate 153 is installed in the fixed cylinder 151; the rotating shaft 154 is rotatably installed on the horizontal plate 153; the blower 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 is meshed and connected with the first bevel gear 143.

[0047] Specifically, when the cross bar 141 rotates, it will drive the first bevel gear 143 to rotate, and then drive the second bevel gear 156 to rotate, and then drive the rotating shaft 154 to rotate, and then drive the blowing fan blades 155 to rotate. The rotating blowing fan blades 155 will transport air into the air outlet pipe 152, and then blow the air to the product located in the die 101 through the air outlet pipe 152, thereby accelerating the cooling speed of the product.

[0048] like Figure 7 As shown, the 3D molded fiberglass board jig also includes a spray 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] The water tank 161 is fixedly connected to the base 100; the piston cylinder 162 is mounted on the mounting frame 104, the piston cylinder 162 is slidably connected with a piston sheet, a piston rod is mounted on the piston sheet, the piston rod passes through the piston cylinder 162 and is slidably connected to the piston cylinder 162. The push plate 163 is fixedly connected to the lower end of the piston rod; one end of the telescopic spring 164 is fixedly connected to the push plate 163, and the other end of the telescopic spring 164 is fixedly connected to the piston cylinder 162.

[0050] One end of the liquid extraction pipe 165 is fixedly connected to the piston cylinder 162, and the other end of the liquid extraction pipe 165 is fixedly connected to the water tank 161; the liquid outlet pipe 166 is installed on the piston cylinder 162; and the atomizing nozzle 167 is installed on the liquid outlet pipe 166. A one-way valve is installed in both the liquid extraction pipe 165 and the liquid outlet pipe 166, so that the water in the water tank 161 can only enter the piston cylinder 162 in one direction through the liquid extraction pipe 165, and the water in the piston cylinder 162 can only enter the atomizing nozzle 167 in one direction through the liquid outlet pipe 166.

[0051] Specifically, when the second cam 144 rotates, it will push the push plate 163 to move, and then drive the piston rod and the piston plate to move, and with the cooperation of the rotating second cam 144 and the telescopic spring 164, the push plate 163 will move back and forth up and down, and then drive the piston rod and the piston plate to move back and forth up and down, and then pump the water in the water tank 161 into the piston cylinder 162, and transport the water in the piston cylinder 162 to the atomizing nozzle 167, so that the water is sprayed in the form of water mist onto the product located in the die 101, thereby accelerating the cooling speed of the product.

[0052] Working principle: When in use, the three-dimensional customized preform is placed into the die 101, and then the hydraulic cylinder 111 is started, so that the extended end of the hydraulic cylinder 111 drives the punch 112 to move downward, and then the punch 112 is inserted into the die 101, so that the punch 112 cooperates with the die 101 to mold the three-dimensional customized preform, and at the same time, the heating plates in the punch 112 and the die 101 are started to heat the punch 112 and the die 101, thereby heating the three-dimensional customized preform.

[0053] After maintaining the pressure for a certain period of time, the product (i.e., the glass fiber mobile phone battery protection plate) is obtained, and then, by starting the hydraulic cylinder 111, the extended 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, and then drives the cross bar 141 to rotate through the small bevel gear 142. When the cross bar 141 rotates, it drives 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 at the same time, the two reciprocating screw nuts 133 will move at the same time, thereby driving the two moving seats 134 to move, and then driving the rotating rod 135 to move horizontally. Since the gear 136 on the rotating rod 135 is engaged 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 cam 137 will lift the movable plate 102 upward, and with the cooperation of the rotating first cam 137 and the support spring 122, the movable plate 102 will move up and down reciprocatingly, thereby facilitating the separation of the product on the movable plate 102 from the die 101, thereby facilitating the removal of the product.

[0056] And when the cross bar 141 rotates, it will drive the first bevel gear 143 to rotate, and then drive the second bevel gear 156 to rotate, and then drive the rotating shaft 154 to rotate, and then drive the blowing fan blades 155 to rotate. The rotating blowing fan blades 155 will transport air into the air outlet pipe 152, and then blow the air to the product located in the die 101 through the air outlet pipe 152, thereby accelerating the cooling speed of the product.

[0057] When the cross bar 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 back and forth up and down, thereby driving the piston rod and the piston plate to move back and forth up and down, and then pumping the water in the water tank 161 into the piston cylinder 162, and transporting the water in the piston cylinder 162 to the atomizing nozzle 167, so that the water is sprayed in the form of water mist onto the product located in the die 101, thereby further accelerating the cooling speed of the product.

[0058] When the temperature of the product drops to a suitable temperature (which can be set manually), the product located above the movable plate 102 is removed.

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

[0060] Step 1: Place the three-dimensional customized preform into the concave mold 101 to ensure accurate positioning;

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

[0062] Step 3: Maintain a certain pressure holding time until the raw materials are solidified to obtain the desired product;

[0063] Step 4: Start the hydraulic cylinder 111 to raise the punch 112, and then start the motor 131 so that the power output shaft of the motor 131 drives a reciprocating screw 132 to rotate, thereby driving the large bevel gear 139 to rotate, and then driving the cross bar 141 to rotate through the small bevel gear 142. When the cross bar 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. When the two reciprocating screw nuts 133 rotate at the same time, the two reciprocating screw nuts 133 will move at the same time, thereby driving The two moving seats 134 move, thereby driving the rotating rod 135 to move horizontally. Since the gear 136 on the rotating rod 135 is meshed 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 under the cooperation of the rotating first cams 137 and the supporting spring 122, the movable plate 102 will reciprocate up and down, so as to facilitate the separation of the product on the movable plate 102 from the concave mold 101;

[0064] Step 5: Start the blower mechanism 150 and the spray mechanism 160 to blow air and spray water mist toward the product to speed up the cooling of the product.

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