Description

Technical Field

[0001] This utility model relates to the field of non-metallic gas cylinder production technology, and in particular to a rapid molding and demolding component for composite material LPG non-metallic gas cylinders. Background Technology

[0002] Composite material LPG (liquefied petroleum gas) non-metallic gas cylinders have advantages such as lightweight, corrosion resistance, and impact resistance, and are gradually replacing traditional steel gas cylinders. They are widely used in fields such as civil gas and industrial fuel. In the production process, the shaping and demolding process is one of the core links that determines the quality, production efficiency, and cost of the gas cylinders.

[0003] In the existing technology, when the preform of a gas cylinder is blow molded, after the preform is formed, the two molds separate from each other, but the preform will get stuck inside one of the mold cavities, making it difficult to get it off for a while. Manual assistance is required to demold it smoothly, which greatly reduces the production efficiency of the preform. To address this, a composite material LPG non-metallic gas cylinder rapid shaping and demolding component has been designed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid molding and demolding component for composite material LPG non-metallic gas cylinders.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rapid molding and demolding assembly for composite LPG non-metallic gas cylinders includes a base. Support plates are fixedly connected to both sides of the top of the base. A single bidirectional lead screw is rotatably connected between the tops of the two support plates. A single guide rod is fixedly connected between the tops of the two support plates. Two molds are symmetrically arranged between the two support plates. An L-shaped threaded plate is fixedly connected to the top of each mold. Each L-shaped threaded plate slides through the guide rod. A circular hole adapted to the guide rod is formed at one end of the top of each L-shaped threaded plate. Each of the two L-shaped screw plates is screwed to one end of a bidirectional lead screw. A screw nut, compatible with the bidirectional lead screw, is fixedly fitted to the top of each L-shaped screw plate. A mold cavity is opened on the side of each mold that is close to the other, and a groove is opened on the top of each mold cavity. A demolding mechanism for rapid demolding is provided on the side of each mold that is far from each other. Through the demolding mechanism, when the two molds separate, the gas in the gas storage cylinder is discharged from the arc-shaped push plate, causing the arc-shaped push plate to move and push the gas cylinder blank out of the mold cavity. When the two molds approach each other, the gas storage cylinder automatically refills.

[0007] Preferably, the demolding mechanism includes an air storage cylinder fixedly connected to the side of the mold away from the mold cavity, a piston slidably connected inside the air storage cylinder, an air supply pipe fixedly sleeved in the middle of the piston, the outer end of the air supply pipe fixedly passing through a support plate, a circular hole adapted to the air supply pipe being opened on the support plate, and a gas one-way valve fixedly connected to the other end of the air supply pipe near the support plate.

[0008] Preferably, the mold has a rectangular hole near the air storage cylinder, and the demolding mechanism further includes a fixed plate fixedly connected to the rectangular hole near the air storage cylinder. Sliding rods are slidably fitted on the top and bottom of the fixed plate, and round holes adapted to the sliding rods are opened on the top and bottom of the fixed plate. The same arc-shaped push plate is fixedly connected to one end of the two sliding rods near the mold cavity, and the arc-shaped push plate is adapted to the mold cavity. A fixing ring is fixedly fitted on one side of the two sliding rods near the arc-shaped push plate, and a limiting plate is fixedly connected to the other end of the two sliding rods. A spring is fitted on one end of the two sliding rods near the limiting plate, and two air holes are also opened on the fixed plate.

[0009] Preferably, both molds are equipped with a cooling mechanism at their tops. The cooling mechanism includes a water tank fixedly connected to the top of an L-shaped screw plate. A second U-shaped tube and a first U-shaped tube are fixedly fitted on both sides of the mold. Circular holes adapted to the first and second U-shaped tubes are opened on both sides of the mold. A T-shaped pipe is fixedly connected to the top of the same end of the second and first U-shaped tubes. The top of each T-shaped pipe is fixedly connected to one side of the water tank. A circulation pump is installed on one of the T-shaped pipes and is fixedly connected to the outside of the water tank. Multiple heat dissipation fins are provided on the outer wall of the water tank. The cooling mechanism allows water to circulate, which can remove heat from the mold and facilitate rapid cooling of the gas cylinder blank.

[0010] Preferably, a bidirectional motor is fixedly connected to the outer side of one of the support plates, and the output end of the bidirectional motor passes through the support plate and is fixedly connected to one end of the bidirectional lead screw via a coupling.

[0011] Preferably, a collection groove is provided at the middle of the top of the base, and a sponge pad is provided inside the collection groove to protect the falling gas cylinder blank.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Due to the adoption of demolding mechanism, mold, bidirectional lead screw and bidirectional motor technology, when the two molds separate, the gas in the gas storage cylinder is discharged from the arc-shaped push plate, causing the arc-shaped push plate to move and push the gas cylinder blank out of the mold cavity. When the two molds come close to each other, the gas storage cylinder is automatically refilled, which effectively solves the problem of demolding difficulty mentioned in the background technology, and realizes the linkage between mold opening and closing and gas storage cylinder filling and exhaust, without manual intervention, adapting to continuous production, automatically pushing the gas cylinder blank, and improving demolding efficiency.

[0014] 2. By setting up a cooling mechanism, water circulates through the first U-shaped tube and the second U-shaped tube, carrying away the heat in the mold, so that the gas cylinder blank inside the mold can be cooled and formed quickly, further improving the production efficiency of the gas cylinder blank.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-4 A rapid molding and demolding assembly for composite LPG non-metallic gas cylinders includes a base 1. Support plates 101 are fixedly connected to both sides of the top of the base 1. A single bidirectional lead screw 104 is rotatably connected between the tops of the two support plates 101. A single guide rod 103 is fixedly connected between the tops of the two support plates 101. Two molds 2 are symmetrically arranged between the two support plates 101. An L-shaped threaded plate 202 is fixedly connected to the top of each mold 2. Each L-shaped threaded plate 202 slides through the guide rod. On rod 103, two L-shaped screw plates 202 are provided with round holes at one end of their tops that are compatible with guide rod 103. The two L-shaped screw plates 202 are screwed to one end of bidirectional lead screw 104 respectively. The top ends of the two L-shaped screw plates 202 are fixedly fitted with lead screw nuts that are compatible with bidirectional lead screw 104. The two molds 2 are provided with mold cavities 201 on the side that are close to each other. The top of the two mold cavities 201 is provided with grooves. The two molds 2 are provided with demolding mechanisms 4 for quick demolding on the side that are far apart from each other.

[0022] In this utility model, the demolding mechanism 4 includes an air storage cylinder 401 fixedly connected to the side of the mold 2 away from the mold cavity 201. A piston 404 is slidably connected inside the air storage cylinder 401. An air supply pipe 402 is fixedly sleeved in the middle of the piston 404. The outer end of the air supply pipe 402 is fixedly inserted through the support plate 101. A round hole adapted to the air supply pipe 402 is opened on the support plate 101. A gas one-way valve 403 is fixedly connected to the other end of the air supply pipe 402 near the support plate 101. The setting of the gas one-way valve 403 ensures that air can only enter the air storage cylinder 401 from the air supply pipe 402 and cannot exit.

[0023] In this invention, the mold 2 has a rectangular hole near the air storage cylinder 401. The demolding mechanism 4 also includes a fixing plate 410 fixedly connected to the rectangular hole near the air storage cylinder 401. Sliding rods 405 are slidably fitted onto the top and bottom of the fixing plate 410. The top and bottom of the fixing plate 410 each have a round hole adapted to the sliding rod 405. The ends of the two sliding rods 405 near the mold cavity 201 are fixedly connected to the same arc-shaped push plate 409, and the arc-shaped push plate 409 is adapted to the mold cavity 201. The two sliding rods 405 are close to the arc-shaped push plate... A fixing ring 406 is fixedly fitted on one side of the 409. The fixing ring 406 allows the arc-shaped push plate 409 to fit with the mold cavity 201 when it is not subjected to air pressure, so that the blow-molded gas cylinder blank has a perfect shape. The other end of the two slide rods 405 is fixedly connected to the limiting plate 407. A spring 408 is fitted on the end of the two slide rods 405 near the limiting plate 407. Two air holes are also opened on the fixing plate 410. The air holes facilitate the air in the air storage cylinder 401 to push the arc-shaped push plate 409.

[0024] In this invention, both molds 2 are equipped with a cooling mechanism 3 at their top. The cooling mechanism 3 includes a water tank 301 fixedly connected to the top of an L-shaped screw plate 202. A second U-shaped tube 305 and a first U-shaped tube 304 are fixedly sleeved on both sides of the mold 2. Both sides of the mold 2 are provided with round holes that are compatible with the first U-shaped tube 304 and the second U-shaped tube 305. A three-way tube 302 is fixedly connected to the top of the same end of the second U-shaped tube 305 and the first U-shaped tube 304. The top of each three-way tube 302 is fixedly connected to one side of the water tank 301. A circulation pump 303 is provided on one of the three-way tubes 302 and is fixedly connected to the outside of the water tank 301. Multiple heat dissipation fins 306 are provided on the outer wall of the water tank 301. The heat dissipation fins 306 can better dissipate heat from the water inside the water tank 301.

[0025] In this utility model, a bidirectional motor 105 is fixedly connected to the outer side of one of the support plates 101, and the output end of the bidirectional motor 105 passes through the support plate 101 and is fixedly connected to one end of the bidirectional lead screw 104 through a coupling.

[0026] In this utility model, a collection groove 102 is provided at the middle of the top of the base 1, and a sponge pad is provided on the inner side of the collection groove 102.

[0027] Working principle: When the device is in use, the preform to be blow-molded, which has already been heated, is placed into the grooves at the top of the two molds 2 when the two molds 2 are in contact with each other. Then, the blow molding machine is controlled to blow-mold the preform, causing it to expand and fit into the mold cavity 201, forming the same shape as the mold cavity 201. At the same time, the three-way pipes 302 of the two cooling mechanisms 3 are activated, allowing water in the water tank 301 to pass through the inside of the mold 2 through the first U-shaped pipe 304 and the second U-shaped pipe 305 and return to the water tank 301. The heat dissipation fins 306 facilitate the dissipation of water inside the water tank 301. The two cooling mechanisms 3 enable the formed gas cylinder preform to be cooled quickly. Then, the bidirectional motor 105 is activated, driving the bidirectional lead screw 104 to rotate, causing the two molds 2 to move away from each other. When the two molds 2 move away from each other, the gas cylinder preform may separate from one of the molds 2. When the two molds 2 move, since the gas supply pipe 402, piston 404 and support plate 101 are a fixed structure, the piston 404 slides in the gas storage cylinder 401 when the mold 2 moves, which compresses the gas inside the gas storage cylinder 401. Since the gas can only enter and not exit at the gas one-way valve 403, the gas inside the gas storage cylinder 401 can only squeeze the arc-shaped push plate 409 through the air hole, causing the arc-shaped push plate 409 to move and compress the spring 408. Through the movement of the arc-shaped push plate 409, the arc-shaped push plate 409 pushes out the gas cylinder blank in the mold cavity 201 and drops it into the collection groove 102 for easy retrieval. The bidirectional motor 105 reverses, causing the two molds 2 to move closer together again. At the same time, the piston 404 moves in the opposite direction in the gas storage cylinder 401, allowing outside air to enter the gas storage cylinder 401 through the gas one-way valve 403.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
