Description

Technical Field

[0001] The invention relates to the technical field of hollow sandwich composite material production equipment, in particular to a novel anti-aging hollow sandwich composite material production equipment. Background Art

[0002] Hollow sandwich composite material components use high-performance fiber (high-strength glass fiber, carbon fiber, etc.) three-dimensional hollow sandwich fabric as reinforcement material and are composited with modified resin. Its overall hollow sandwich structure has excellent mechanical, flame retardant, sound insulation, heat insulation and other properties, overcoming the shortcomings of traditional honeycomb, foam and other sandwich composite materials that are easy to delaminate and have poor impact resistance. It is widely used in load-bearing structural parts and auxiliary parts of rail transit vehicles, which can reduce vehicle weight and energy and improve overall performance. When manufacturing hollow panels, it is necessary to go through mold closing, high-pressure and low-speed film locking, injection of melt, pressure holding, cooling and solidification, and mold opening.

[0003] In the existing device, the cooling time is relatively long, which will result in a slow production speed. During long-term continuous working, the temperature of the mold will become higher and higher, and it is impossible to cool down quickly. This will only make the cooling and molding time of the hollow plate longer, which is not practical.

[0004] Therefore, a new type of production device for anti-aging hollow sandwich composite materials is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a new type of anti-aging hollow sandwich composite material production device, so that the coolant inside the upper mold and the lower mold can be replaced every time during preparation, and cooling is carried out after each processing, which is beneficial to the cooling and solidification of the molten material, improves the processing efficiency of the device, and makes the device more practical, so as to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a novel anti-aging hollow sandwich composite material production device, comprising a shell, both sides of the upper inner wall of the shell are fixedly connected with electric telescopic rods, the lower ends of the electric telescopic rods are commonly fixedly connected with an upper mold, the middle part of the lower end of the upper mold is fixedly connected with a feed pipe, and the lower inner wall of the shell is movably connected with a lower mold;

[0007] A circulating cooling mechanism is provided at the lower end of the lower mold;

[0008] The circulating cooling mechanism can accelerate the cooling and solidification time of the hollow plate melt.

[0009] When processing is about to be carried out, the electric telescopic rod is extended to move the upper mold downward, and the upper mold drives the feed pipe to move downward. When the upper mold overlaps with the lower mold, the molten material is injected into the upper mold and the lower mold through the feed pipe. The circulating cooling mechanism can shorten the cooling time of the molten material and improve the processing efficiency.

[0010] Preferably, the circulating cooling mechanism includes a first rod, the first rod is fixedly connected to the lower end of the lower mold near the two sides, the positions on both sides of the inner wall of the lower end of the shell are fixedly connected to the sleeve, the interior of the sleeve is fixedly connected to a first spring, the upper end of the first spring is fixedly connected to the lower end of the first rod, the middle part of the lower end of the lower mold is fixedly connected to a second rod, the lower end of the second rod is fixedly connected to a first piston, the periphery of the first piston is fixedly connected to the inner surface of the bottom of the shell with baffles that are evenly arranged and perpendicular to each other, and the adjacent baffles are mutually perpendicular. They are fitted and fixedly connected to form a water storage tank together, the right side of the water storage tank is fixedly connected with a water inlet pipe, the material of the water inlet pipe is flexible material, the inside of the lower mold and the upper mold are both fixedly connected with a first water pipe, both sides of the first water pipe at the lower end are fixedly connected with a second water pipe, the inner wall of the second water pipe is slidably connected with a third water pipe, the two sides of the first water pipe at the upper end are fixedly connected with the upper end of the corresponding third water pipe, the lower end of the second water pipe on the left side is fixedly connected with a water outlet pipe, the second water pipe is communicated with the water inlet pipe, and the pipe wall of the water outlet pipe is fixedly connected with a one-way valve.

[0011] After the electric telescopic rod drives the upper mold to move downward and overlap with the lower mold, the electric telescopic rod continues to extend. At this time, the lower mold moves downward, driving the first rod to move downward while compressing the first spring. When the lower mold moves downward, it drives the second rod to move downward. When the second rod moves downward, it drives the first piston to move downward, and the coolant inside the water storage tank enters the second water pipe on the right through the water inlet pipe, and then enters the first water pipe and the third water pipe from the second water pipe, and flows out from the water outlet pipe. In this way, the internal cooling is replaced every time the processing is prepared, which improves the heat dissipation effect. When the upper mold moves downward and overlaps with the lower mold, the third water pipe slides inside the second water pipe, and the coolant can flow in only one direction through the set one-way valve.

[0012] Preferably, a pressure valve is fixedly connected inside the second water pipe on the right side.

[0013] When the upper and lower first water pipes are changing water, the water changing of the upper first water pipe is not ideal due to the height difference. At this time, the pressure valve can make up for the height difference, thereby improving the effect of liquid changing.

[0014] Preferably, a cross bar is fixedly connected to the inner wall of the water outlet pipe near the lower end, a blade is rotatably connected to the lower end of the cross bar, and a stirring rod is fixedly connected to the lower end of the blade.

[0015] When the coolant is discharged from the lower end of the outlet pipe through the coolant, the water flow drives the blades to rotate, and the rotation of the blades drives the stirring rod to rotate, stirring the coolant with a higher temperature that has just been replaced, thereby accelerating its heat dissipation.

[0016] Preferably, the second rod is rotatably connected to the inside of a third rod, a threaded rod is fixedly connected to the center of the inner wall of the lower end of the water storage tank, the inside of the third rod is spirally transmitted with the rod wall of the threaded rod, a first cavity is opened inside the lower mold, the upper end of the third rod is fixedly connected to a turntable, grooves are opened on both sides of the turntable, a second spring is fixedly connected to the inside of the groove, the upper end of the second spring is fixedly connected to a first protrusion, and the upper end of the first cavity near both sides is fixedly connected to second protrusions.

[0017] When the molten material cools down, the first spring causes the first rod to move upward, the first rod drives the lower mold to move upward, the upper mold drives the second rod to move upward, and the second rod drives the third rod to move upward. Because the third rod and the threaded rod are spirally transmitted, the third rod rotates under the action of the threaded rod when it moves upward, and the rotation of the third rod drives the turntable to rotate, and the rotation of the turntable drives the first protrusion to rotate. When the first protrusion contacts the second protrusion, the first protrusion moves toward the inside of the groove and compresses the second spring at the same time. When the first protrusion is misaligned with the second protrusion, the upper end of the first cavity is knocked to generate vibration, which is conducive to the later demolding and makes demolding easier.

[0018] Preferably, the first protrusion and the second protrusion have arc-shaped opposite ends.

[0019] The first protrusion is made to shrink better and knock the upper end of the first cavity.

[0020] Preferably, the height of the coolant contained in the baffle is higher than the height of the water storage tank.

[0021] Make sure the water tank is full every time.

[0022] Preferably, the first pipe is in a curved shape inside the upper mold and the lower mold.

[0023] Make the coolant contact the upper mold and the lower mold with the largest area to improve the cooling effect.

[0024] Preferably, the lower end of the upper mold is fixedly connected with an insertion rod near both sides, the lower mold is provided with a second cavity near both sides, the second cavity is slidably connected with a second piston, the lower end of the second piston is fixedly connected with a third spring, the second cavity is fixedly connected with an air pipe on one side near the center of the lower mold, the air pipe is slidably connected with the third piston on one side near the first cavity, the upper end of the third piston is fixedly connected with a support rod, and the upper end of the support rod is fixedly connected with a top block.

[0025] When the upper mold moves downward, it drives the insertion rod downward, and the insertion rod is inserted into the interior of the second cavity when moving downward, so that the second piston moves downward and squeezes the third spring at the same time. It is explained here that when the insertion rod is inserted into the second cavity, the second cavity is connected to the air pipe, and when the second piston descends, the pressure inside the air pipe is reduced, so that the third piston remains at the bottom of the air pipe. When cooling is completed, the insertion rod moves upward with the upper mold. At this time, the second piston moves upward under the action of the third spring. At this time, the air pressure inside the air pipe increases, causing the third piston to move upward, and the third piston drives the support rod to move upward, and the support rod drives the top block to move upward, which can help the hollow plate to separate from the lower mold.

[0026] Preferably, the front end of the insertion rod is fixedly connected with a soft pad.

[0027] The force exerted by the plunger on the second piston can be dispersed to reduce mechanical loss.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] In this way, the coolant inside the upper mold and the lower mold can be replaced every time preparation is carried out, and cooling is carried out after each processing, which is conducive to the cooling and solidification of the molten material, improves the processing efficiency of the device, and makes the device more practical;

[0030] By knocking the upper end of the first cavity to generate vibration, it is beneficial to the later demoulding, making the demoulding easier, improving the practicability of the device and accelerating the processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The circulating cooling mechanism can accelerate the cooling and solidification time of the hollow plate melt;

[0042] During operation, when processing is about to be carried out, the electric telescopic rod 2 is extended to move the upper mold 3 downward, and the upper mold 3 drives the feed pipe 39 to move downward. When the upper mold 3 overlaps with the lower mold 9, the molten material is injected into the upper mold 3 and the lower mold 9 through the feed pipe 39. The circulating cooling mechanism can shorten the cooling time of the molten material and improve the processing efficiency.

[0043] As an embodiment of the present invention, Figure 3 As shown, the circulating cooling mechanism includes a first rod 15, which is fixedly connected to the lower end of the lower mold 9 near the two sides, and the positions on both sides of the lower inner wall of the shell 1 are fixedly connected to the sleeve 17, and the first spring 16 is fixedly connected inside the sleeve 17, and the upper end of the first spring 16 is fixedly connected to the lower end of the first rod 15. The middle part of the lower end of the lower mold 9 is fixedly connected to the second rod 10, and the lower end of the second rod 10 is fixedly connected to the first piston 31. The outer periphery of the first piston 31 is fixedly connected to the inner surface of the bottom of the outer shell 1 with baffles 11 that are evenly arranged and perpendicular to each other, and the adjacent baffles 11 are fitted and fixedly connected to each other to form a water storage tank, and the center of the lower inner wall of the shell 1 is fixedly connected to the water storage tank 18 , the right side of the water storage tank 18 is fixedly connected with a water inlet pipe 12, the material of the water inlet pipe 12 is a flexible material, the lower mold 9 and the upper mold 3 are fixedly connected with the first water pipe 4, the first water pipe 4 installed in the lower mold 9 is fixedly connected with the second water pipe 6 on both sides, the inner wall of the second water pipe 6 is slidably connected with the third water pipe 5, the two sides of the upper end of the first water pipe 4 are fixedly connected with the upper end of the corresponding third water pipe 5, the lower end of the second water pipe 6 on the left side is fixedly connected with a water outlet pipe 14, the second water pipe 6 is connected with the water inlet pipe 12, the pipe wall of the water outlet pipe 14 is fixedly connected with a one-way valve 13, the inside of the second water pipe 6 on the right side is fixedly connected with a pressure valve 37, and the height of the coolant installed in the baffle 11 is higher than the height of the water storage tank 18;

[0044] During operation, the electric telescopic rod 2 drives the upper mold 3 to move downward and overlap with the lower mold 9, and the electric telescopic rod 2 continues to extend. At this time, the lower mold 9 moves downward, driving the first rod 15 to move downward while compressing the first spring 16. When the lower mold 9 moves downward, it drives the second rod 10 to move downward. When the second rod 10 moves downward, it drives the first piston 31 to move downward, and the coolant inside the water storage tank 18 enters the inside of the second water pipe 6 on the right through the water inlet pipe 12, and then enters the first water pipe 4 and the third water pipe 5 from the second water pipe 6, and flows out from the water outlet pipe 14. In this way, the internal cooling is further performed each time the processing is prepared. The cooling effect is improved. When the upper mold 3 moves down and overlaps with the lower mold 3, the third water pipe 5 slides inside the second water pipe 6. The one-way valve 13 is set to allow the coolant to flow in only one direction. When the upper and lower first water pipes 4 are changing water, the height difference makes the water change of the upper first water pipe 4 unsatisfactory. At this time, the pressure valve 37 can make up for the height difference and improve the effect of changing the liquid. In this way, the coolant inside the upper mold 3 and the lower mold 9 can be replaced every time preparation is carried out, and cooling is carried out after each processing, which is beneficial to the cooling and solidification of the molten material, improves the processing efficiency of the device, and makes the device more practical.

[0046] During operation, when the coolant is discharged from the lower end of the water outlet pipe 14, the water flow drives the blades 29 to rotate, and the rotation of the blades 29 drives the stirring rod 30 to rotate, stirring the coolant with a higher temperature just replaced, accelerating its heat dissipation, which is beneficial to the subsequent recycling of the coolant.

[0047] As an embodiment of the present invention, Figure 3 and Figure 5 As shown, the interior of the second rod 10 is rotatably connected to the third rod 36, the center of the inner wall of the lower end of the water storage tank 18 is fixedly connected to the threaded rod 20, the interior of the third rod 36 is spirally transmitted with the rod wall of the threaded rod 20, the interior of the lower mold 9 is provided with a first cavity 32, the upper end of the third rod 36 is fixedly connected to the rotating disk 33, both sides of the rotating disk 33 are provided with grooves 7, the interior of the groove 7 is fixedly connected to the second spring 35, the upper end of the second spring 35 is fixedly connected to the first protrusion 38, the upper end of the first cavity 32 is fixedly connected to the second protrusion 34 near the two sides, the first protrusion 38 and the second protrusion 34 are both arc-shaped at the opposite ends;

[0048] During operation, after the melt cools down, the first spring 16 causes the first rod 15 to move upward, the first rod 15 drives the lower mold 9 to move upward, the upper mold 9 drives the second rod 10 to move upward, and the second rod 10 drives the third rod 36 to move upward. Because the third rod 36 and the threaded rod 20 are spirally transmitted, the third rod 36 rotates under the action of the threaded rod 20 when it moves upward, and the rotation of the third rod 36 drives the turntable 33 to rotate, and the rotation of the turntable 33 drives the first protrusion 38 to rotate. When the first protrusion 38 contacts the second protrusion 34, the first protrusion 38 moves toward the inside of the groove 7 and compresses the second spring 35. When the first protrusion 38 is misaligned with the second protrusion 34, the upper end of the first cavity 32 is knocked to generate vibration, which is beneficial to the later demoulding, makes demoulding easier, improves the practicability of the device, and speeds up the processing efficiency.

[0049] As an embodiment of the present invention, Figure 3 and Figure 4 As shown, the lower end of the upper mold 3 is fixedly connected with an insertion rod 19 near both sides, the lower mold 9 is provided with a second cavity 21 near both sides, the second cavity 21 is slidably connected with a second piston 22, the lower end of the second piston 22 is fixedly connected with a third spring 23, the second cavity 21 is fixedly connected with an air pipe 24 on one side near the center of the lower mold 9, the air pipe 24 is slidably connected with a third piston 25 on one side near the first cavity 32, the upper end of the third piston 25 is fixedly connected with a support rod 27, and the upper end of the support rod 27 is fixedly connected with a top block 26;

[0050] During operation, when the upper mold 3 moves downward, it drives the insertion rod 19 to move downward. When moving downward, the insertion rod 19 is inserted into the second cavity 21, so that the second piston 22 moves downward and squeezes the third spring 23. It is explained here that when the insertion rod 19 is inserted into the second cavity 21, the second cavity 21 is connected with the air pipe 24. When the second piston 22 descends, the internal pressure of the air pipe 24 is reduced, so that the third piston 25 is maintained at the bottom of the air pipe 24. When cooling is completed, the insertion rod 19 moves upward with the upper mold 3. At this time, the second piston 22 moves upward under the action of the third spring 23. At this time, the air pressure inside the air pipe 24 increases, so that the third piston 25 moves upward, and the third piston 25 drives the support rod 27 to move upward, and the support rod 27 drives the top block 26 to move upward, which can help the hollow plate to separate from the lower mold 9, making the device more convenient when taking out parts.

[0051] Working principle:

[0052] During operation, when processing is about to be carried out, the electric telescopic rod 2 is extended to make the upper mold 3 move downward, and the upper mold 3 drives the feed pipe 39 to move downward. When the upper mold 3 overlaps with the lower mold 9, the molten material is injected into the upper mold 3 and the lower mold 9 through the feed pipe 39. The circulating cooling mechanism can shorten the cooling time of the molten material and improve the processing efficiency. After the electric telescopic rod 2 drives the upper mold 3 to move downward and overlap with the lower mold 9, the electric telescopic rod 2 continues to extend. At this time, the lower mold 9 moves downward, driving the first rod 15 to move downward while compressing the first spring 16. When the lower mold 9 moves downward, it drives the second rod 10 to move downward. When the second rod 10 moves downward, it drives The first piston 31 moves downward, and the coolant in the water storage tank 18 enters the second water pipe 6 on the right through the water inlet pipe 12, and then enters the first water pipe 4 and the third water pipe 5 from the second water pipe 6, and flows out from the water outlet pipe 14. In this way, the internal cooling is replaced every time the processing is prepared, which improves the heat dissipation effect. When the upper mold 3 moves down and overlaps with the lower mold 3, the third water pipe 5 slides inside the second water pipe 6, and the coolant can flow in only one direction through the set one-way valve 13. When the upper and lower first water pipes 4 are changing water, the water change of the upper first water pipe 4 is not ideal due to the height difference. At this time, the pressure valve 37 can make up for this height difference, thereby improving the effect of changing the liquid;In this way, the coolant inside the upper mold 3 and the lower mold 9 can be replaced every time preparation is performed, and cooling is performed after each processing, which is beneficial to the cold solidification of the molten material, improves the processing efficiency of the device, and makes the device more practical. When the coolant is discharged from the lower end of the water outlet pipe 14 through the coolant, the water flow drives the blade 29 to rotate, and the rotation of the blade 29 drives the stirring rod 30 to rotate, stirring the coolant with a higher temperature just replaced, accelerating its heat dissipation, and facilitating the recycling of the coolant in the later stage. When the molten material is cooled, the first spring 16 makes the first rod The first rod 15 moves upward, the first rod 15 drives the lower mold 9 to move upward, the upper mold 9 drives the second rod 10 to move upward, and the second rod 10 drives the third rod 36 to move upward. Because the third rod 36 and the threaded rod 20 are spirally driven, the third rod 36 rotates under the action of the threaded rod 20 when it moves upward, and the rotation of the third rod 36 drives the turntable 33 to rotate, and the rotation of the turntable 33 drives the first protrusion 38 to rotate, and when the first protrusion 38 contacts the second protrusion 34, the first protrusion 38 moves toward the inside of the groove 7 and compresses the third protrusion 38. The second spring 35, when the first protrusion 38 is misaligned with the second protrusion 34, the upper end of the first cavity 32 is knocked to generate vibration, which is conducive to the later demoulding, makes demoulding easier, improves the practicality of the device, and speeds up the processing efficiency. When the upper mold 3 moves downward, it drives the insertion rod 19 to move downward. When the insertion rod 19 moves downward, it is inserted into the interior of the second cavity 21, so that the second piston 22 moves downward and squeezes the third spring 23 at the same time. It is explained here that when the insertion rod 19 is inserted into the second cavity 21, the second cavity 21 and the trachea are in contact. 24 is connected, when the second piston 22 descends, the pressure inside the air pipe 24 is reduced, so that the third piston 25 is kept at the bottom of the air pipe 24. When cooling is completed, the insertion rod 19 moves upward with the upper mold 3. At this time, the second piston 22 moves upward under the action of the third spring 23. At this time, the air pressure inside the air pipe 24 increases, so that the third piston 25 moves upward, and the third piston 25 drives the support rod 27 to move upward, and the support rod 27 drives the top block 26 to move upward, which can help the hollow plate to separate from the lower mold 9, making the device more convenient when taking out. ;
