[0002] Small hulls are generally made of plastic materials, and in the process of plastic material production, hot pressing molds are required to soften the plastic and make the material fit the mold, and finally cool it down to form.

[0020] 3. By starting the dual-axis motor to drive the adjusting screws on both sides to rotate, the limit cooperation between the moving slide groove and the moving slide plate is utilized, so that when the screw sleeve cooperates with the adjusting screw thread, the position of the moving slide plate will be adjusted, and the arc sleeve plate will be pulled or pushed to move in the corresponding direction. During its movement, the positions of several arc sleeve plates and arc connecting plates can be synchronized by using the arc connecting plate, so as to control the diameter distance between the arc sleeve plates and the arc connecting plates, and then the distance opened by the discharge port can be accurately adjusted, so that the application can freely adjust the thickness of the material forming as needed, and avoid the problem of excessive material thickness deviation during subsequent hedging forming due to uneven thickness during extrusion.

[0037] The following will be combined with 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 making creative work are within the scope of protection of the present invention.

[0038] like Figures 1 to 15 As shown, a small hull ramming and hot pressing mold comprises a support 1, a first slide rail 2 is fixedly installed on the lower side of the support 1, a mold body 3 is slidably installed on the upper side of the first slide rail 2, a hydraulic cylinder 4 is fixedly installed in the middle of the support 1, and the output end of the hydraulic cylinder 4 is fixedly connected to the mold body 3, a bracket 5 is fixedly installed on the upper end of the support 1, a feeding component 6 for conveying molding material is fixedly installed in the middle of the bracket 5, and an auxiliary component 7 for material segmentation is arranged on one side of the feeding component 6.

[0039] By starting the hydraulic cylinder 4, the mold body 3 can be pushed to move on the upper side of the first slide rail 2, so that the mold bodies 3 on both sides can punch and shape the material in the middle, and continuous molding operation can be achieved by cooperating with the feeding component 6 above to continuously feed the material.

[0040] In this embodiment, the feeding assembly 6 includes a cylinder 601, which is fixedly installed in the middle of the support 1. The cylinder 601 is provided with a heating cavity 602, an exchange hole 603 and an extrusion cavity 604 from top to bottom. A discharge port 613 is provided at the bottom of the extrusion cavity 604. Electric heating coils 607 for heating materials are installed inside the heating cavity 602 and the extrusion cavity 604.

[0041] A fixing frame 6021 is fixedly installed on the upper end of the heating cavity 602, a driving motor 6022 is fixedly installed on the upper end of the fixing frame 6021, and a stirring shaft 6023 is fixedly installed on the output end of the driving motor 6022;

[0042] After the material is added to the heating cavity 602, the electric heating coil 607 is started to heat the internal material to soften it. During the heating process, the driving motor 6022 is started to drive the stirring shaft 6023 to rotate, so that the stirring shaft 6023 can stir the material inside the current heating cavity 602 during the rotation process, so that it can be heated more fully.

[0043] The bottom end of the stirring shaft 6023 extends into the extrusion cavity 604 through the exchange hole 603, a plurality of fixed blades 6024 are fixedly installed on one side of the stirring shaft 6023, and a flip frame 6025 is fixedly installed on the other side of the stirring shaft 6023. A plurality of movable blades 6026 are flipped and installed on the surface of the flip frame 6025, and each fixed blade 6024 and movable blade 6026 are combined into a spiral blade.

[0044] After the material is softened by heat, the stirring shaft 6023 is driven to rotate by the driving motor 6022, so that the fixed blade 6024 and the movable blade 6026 at the lower end of the stirring shaft 6023 squeeze the material inside the heating cavity 602 into the exchange hole 603, and then continue to rotate and gradually squeeze it into the extrusion cavity 604. During the operation, the inside of the extrusion cavity 604 is completely filled with the heated material, and then the fixed blade 6024 and the movable blade 6026 above continue to squeeze, so that the material inside the extrusion cavity 604 is discharged according to the distance between the discharge port 613 and the arc sleeve plate 6052 and the arc connecting plate 6053, so as to achieve stable discharge operation;

[0045] The present application has adjusted the space of the discharge port 613 by changing the diameter of the arc sleeve plate 6052 and the arc connecting plate 6053, thereby adjusting the thickness of the material. In order to avoid the situation where the feeding amount of the spiral blade is changed after the discharge amount is adjusted, resulting in excessive material inside the extrusion cavity 604 and causing the material to leak out, causing the thickness of the material to be uncontrollable, the present application divides the spiral blade into a fixed blade 6024 and a movable blade 6026, so that when there is too much material, the movable blade 6026 cooperates with the flip frame 6025 to achieve a certain angle of flipping, thereby preventing part of the material from being squeezed, and adaptively adjusting the discharge amount of the discharge port 613 accordingly.

[0046] In the present application, a fixed tube 608 is fixedly installed inside the extrusion cavity 604, a material guide seat 605 is fixedly installed in the middle of the fixed tube 608, a movable slide groove 6051 is provided at the bottom of the material guide seat 605, and movable slide plates 6054 are slidably installed on both sides of the movable slide groove 6051, and an arc-shaped sleeve plate 6052 is fixedly installed at the bottom of the movable slide plate 6054. A plurality of arc-shaped sleeve plates 6052 are provided, and an arc-shaped connecting plate 6053 is interspersed between every two arc-shaped sleeve plates 6052. The arc-shaped sleeve plates 6052 and the arc-shaped connecting plates 6053 are located at the discharge port 613.

[0047] During the specific setting, an extension frame 610 is fixedly installed at the bottom of the material guide seat 605, a dual-axis motor 611 is fixedly installed inside the extension frame 610, an adjusting screw rod 612 is fixedly installed at the output end of the dual-axis motor 611, and a screw sleeve 6055 is fixedly installed on one side of the movable slide plate 6054 on both sides, and the screw sleeve 6055 is threadedly matched with the adjusting screw rod 612 on the corresponding side.

[0048] By starting the dual-axis motor 611 to drive the adjusting screw rods 612 on both sides to rotate, the limit cooperation between the movable slide groove 6051 and the movable slide plate 6054 is utilized, so that when the screw sleeve 6055 is threadedly engaged with the adjusting screw rod 612, the position of the movable slide plate 6054 will be adjusted, and the arc sleeve plate 6052 will be pulled or pushed to move in the corresponding direction. During its movement, the arc connecting plate 6053 can be used to synchronize the positions of several arc sleeve plates 6052 and the arc connecting plate 6053, so as to control the diameter distance between the arc sleeve plates 6052 and the arc connecting plate 6053, and then the distance opened by the discharge port 613 can be accurately adjusted, so that the application can freely adjust the thickness of the material forming as needed, and avoid the problem of excessive material thickness deviation during subsequent counter-forming due to uneven thickness during extrusion.

[0049] It should be noted that an air pump 606 is fixedly installed on the outside of the cylinder 601 , and the outlet end of the air pump 606 is connected to a fixed pipe 608 , and an air charging channel 609 is opened through the fixed pipe 608 and the center of the material guide seat 605 .

[0050] During the punching molding process, the air pump 606 is started to discharge gas from the inflation channel 609 into the molding material, so that the molding material will swell and can fully fit with the mold body 3, further improving the molding accuracy.

[0051] In the application, the auxiliary component 7 includes a second electric slide rail 701, which is fixedly mounted on the outside of the cylinder 601, a slide seat 702 is slidably mounted inside the second electric slide rail 701, a moving frame 703 is fixedly mounted on the bottom of the slide seat 702, and an upper clamping plate 704 is slidably mounted inside the moving frame 703 through an electric push rod 7043;

[0052] An electric push rod 7043 is fixedly mounted on the outer side of the upper clamping plate 704 , a mounting frame 7041 is fixedly mounted on the output end of the electric push rod 7043 , and a cutter 7042 for cutting materials is fixedly mounted on the upper end of the mounting frame 7041 .

[0053] Among them, a first electric slide rail 8 is fixedly installed in the middle of the first slide rail 2, and lower clamping plates 9 for cooperating with the upper clamping plate 704 to clamp materials are slidably installed on both sides inside the first electric slide rail 8.

[0054] In order to facilitate personnel to take the finished product, the second electric slide rail 701 is started to move the slide 702, and the upper clamping plate 704 is located on both sides of the material, and then the upper clamping plate 704 is tightened by the electric push rod 7043. In this process, another electric push rod 7043 is used again to drive the cutter 7042 to cut the material, and then the slide 702 is reset, so that the finished product can be automatically taken out;

[0055] In order to prevent the gas from leaking too quickly during blowing, the first electric slide rail 8 is started so that the lower clamping plates 9 on both sides clamp the lower end of the material, which can ensure that the gas does not leak too quickly and ensure that the material can be bulged.

[0056] The working principle of a small hull hedging hot pressing mold:

[0057] When in use, the material is first stored in the heating cavity 602, and the electric heating coil 607 is activated to heat the internal material to soften it;

[0058] After the material is softened by heat, the stirring shaft 6023 is driven to rotate by the driving motor 6022, so that the fixed blade 6024 and the movable blade 6026 at the lower end of the stirring shaft 6023 squeeze the material inside the heating cavity 602 into the exchange hole 603, and then continue to rotate and gradually squeeze it into the extrusion cavity 604;

[0059] During this process, the material will be continuously squeezed, so that the bottom material will be discharged according to the size of the current discharge port 613, and the material will continue to be pulled downward. During the pulling process, the air pump 606 is started to discharge the gas from the inflation channel 609 into the molding material, so that the molding material will bulge. After the material is pulled out, the bottom of the material is clamped by the lower clamping plates 9 on both sides by starting the first electric slide rail 8, completing the operation of loading the material before the punch molding;

[0060] Then, the hydraulic cylinder 4 is started to push the mold body 3 to move on the upper side of the first slide rail 2, so that the mold bodies 3 on both sides press the middle material to form. During the forming process, if the internal gas is not completely discharged, the operator needs to manually poke the material to deflate it to avoid excessive gas affecting the forming effect of the material;

[0061] After the forming is completed, the second electric slide rail 701 is started to move the slide 702 and make the upper clamp 704 located on both sides of the material. Then, the upper clamp 704 is tightened by the electric push rod 7043. During this process, another electric push rod 7043 is used again to drive the cutter 7042 to cut the material. Then, the slide 702 is reset to realize the automatic removal operation of the finished product.

[0062] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
