Description

Technical Field

[0001] This utility model relates to the field of molding machine technology, specifically a compact molding machine. Background Technology

[0002] A molding machine, commonly known as a hydraulic press, is a crucial and widely used piece of equipment in the industrial field. It primarily undertakes precision processing tasks such as pressing and shaping various materials, including metals, plastics, and rubber, playing an indispensable role in many production stages.

[0003] However, traditional molding machines suffer from a series of problems that urgently need to be addressed. The precision of the components in the original equipment is relatively low, making it difficult to guarantee extremely high processing accuracy during operation. Furthermore, the loose arrangement of its internal components not only results in a bulky overall layout and a significant increase in equipment weight, making handling and installation extremely inconvenient, but also leads to an excessive footprint and a huge waste of production space. Therefore, we propose a compact molding machine. Utility Model Content

[0026] The following description is intended to disclose the present invention and to enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0027] Example 1: Please refer to Figures 1-6The diagram illustrates a compact molding press, comprising a frame 1 made of high-strength alloy steel, possessing excellent rigidity and stability, capable of withstanding significant pressure and impact, ensuring no deformation during prolonged operation. An electrical control box 2 is mounted on the frame 1, constructed of high-quality cold-rolled steel plate with anti-corrosion treatment and neat internal wiring to effectively protect electrical components. A touchscreen 3, featuring a high-definition LCD display, provides sensitive operation and facilitates parameter setting and monitoring by the operator. A molding chamber 5, made of stainless steel, is mounted on the frame 1, offering excellent corrosion resistance and thermal conductivity. An extrusion die 6 is positioned above the molding chamber 5, its key components forged from high-strength alloy steel, precision-machined and heat-treated to provide stable and powerful extrusion force. The press also includes: a heating / cooling component 7 installed inside the molding chamber 5 to assist in workpiece molding; and an ejector component 8 installed inside the molding chamber 5 to assist in workpiece demolding.

[0028] For further details, please refer to Figures 3-6 The heating and cooling components 7 include a concave water tank 14 installed inside the molding chamber 5. The concave water tank 14 is welded from high-quality stainless steel plate, ensuring good sealing and resistance to rust. Its outer surface is coated with a waterproof layer and a heat-insulating coating. A water pump 9 is installed on top of the concave water tank 14. The water pump 9 is a high-efficiency centrifugal pump, whose flow rate and head meet the system requirements. An input pipe 10 is fixedly connected to the input end of the water pump 9, and the input pipe 10 is fixedly connected to and communicates with the concave water tank 14. An output pipe 11 is fixedly connected to the output end of the water pump 9. A three-way pipe 12 is connected to the outside of the output pipe 11. The three-way pipe 12 is made of copper, which is corrosion-resistant and has good sealing performance. Control valves 13 are symmetrically connected to the outside of the three-way pipe 12, enabling precise control of the water flow direction.

[0029] A cooling tank 15 and a heating tank 16 are symmetrically fixedly connected to the top of the concave water tank 14. The cooling tank 15 and the heating tank 16 are made of high-quality heat-insulating material for their outer shells. The cooling tank 15 and the heating tank 16 are respectively installed with a condenser tube 17 and a heating tube 24. The condenser tube 17 is made of copper tube with good thermal conductivity, and the heating tube 24 is made of stainless steel electric heating tube with high heating efficiency. One end of the condenser tube 17 and the heating tube 24 are fixedly connected to a three-way pipe 12, and the other end of the condenser tube 17 and the heating tube 24 are fixedly connected to a return pipe 18. The return pipe 18 is also made of stainless steel to ensure smooth water circulation. Both return pipes 18 are fixedly connected to the concave water tank 14 and are in communication with each other.

[0030] Example 2: This embodiment is a further explanation of Example 1, based on... Figure 3 , Figure 4 and Figure 5As shown, it is worth noting that both the cooling box 15 and the heating box 16 are connected by vertical pipes 19, which are made of stainless steel. Multiple vertical pipes 19 are connected by horizontal pipes 20, and extrusion plates 29 are fixedly connected to the top of each vertical pipe 19. Molds 21 are evenly installed on the top of the extrusion plates 29.

[0031] For details, please refer to Figure 3 Each mold 21 has microchannels 22 inside, and metal tubes 23 are installed inside the microchannels 22. The metal tubes 23 can conduct heat better, promoting the heating and cooling of the material. Multiple microchannels 22 are connected to the cooling box 15 and the heating box 16 through vertical pipes 19. When the material enters the mold 21 in the forming chamber 5 through the feed port, the hot air inside the heating box 16 enters the mold 21 through the vertical pipes 19 to heat the material and facilitate forming. After the extrusion module 6 extrudes and forms the material, the cold air inside the cooling box 15 enters the mold 21 through the vertical pipes 19 to accelerate the cooling of the material inside the mold 21, thereby improving the material production efficiency. The heating and cooling functions are integrated into one unit, thereby reducing the floor space occupied.

[0032] Further reference Figure 3 - Figure 5 As shown, the ejector component 8 includes an electric telescopic rod 25. The stroke 25 and thrust of the electric telescopic rod can meet the demolding requirements. The electric telescopic rod 25 is installed on the concave water tank 14. The output end of the electric telescopic rod 25 is fixedly connected to a long plate 26. The long plate 26 is made of high-strength aluminum alloy, which is lightweight and strong. The top of the long plate 26 is fixedly connected to a push rod 27. The push rod 27 is made of stainless steel and the surface is polished so that it can slide smoothly in the mold 21. The top of the push rod 27 passes through the mold 21 and is fixedly connected to a push plate 28. The push plate 28 is made of wear-resistant and high-temperature resistant plastic material, which can effectively protect the surface of the mold 21. The long plate 26 has a through hole for the vertical tube 19 to pass through, and the long plate 26 and the vertical tube 19 do not contact each other to avoid mutual interference.

[0033] At the same time, refer to Figure 1 As shown, a cylinder 4 is installed on the frame 1. The output end of the cylinder 4 passes through and extends into the molding chamber 5. The cylinder 4 is used to assist the ejector component 8 in discharging the workpiece. After the workpiece is formed, the electric telescopic rod 25 extends and ejects the workpiece from the mold 21 through the long plate 26, push rod 27 and push plate 28. The cylinder 4 further provides auxiliary thrust to ensure that the workpiece is discharged smoothly.

[0034] The principle behind this solution is as follows:

[0035] First, when the material enters the molding chamber 5 through the feeding platform, the extrusion module 6 is activated via the touch screen 3 to extrude and mold the material. During this process, the water pump 9 draws water from the concave water tank 14 and delivers it to the tee pipe 12 through the output pipe 11. When heating is required, the control valve 13 opens the channel to the heating box 16, and the water enters the heating box 16 and is heated by the heating pipe 24. Then, it flows back to the concave water tank 14 through the return pipe 18. The hot air inside the heating box 16 enters the mold 21 through the vertical pipe 19 to heat the material and facilitate molding.

[0036] Secondly, when cooling is required, the control valve 13 opens the channel to the cooling box 15, and the water enters the cooling box 15 and is cooled by the condenser 17. Then it flows back to the concave water tank 14 through the return pipe 18. The cold air inside the cooling box 15 enters the mold 21 through the vertical pipe 19, which can accelerate the cooling of the material inside the mold 21, thereby improving the material production efficiency.

[0037] Finally, after the workpiece is formed, the electric telescopic rod 25 extends and pushes the workpiece out of the mold 21 through the long plate 26, push rod 27 and push plate 28. The cylinder 4 further provides auxiliary thrust to ensure that the workpiece is discharged smoothly.

[0038] It should be noted that the touch screen 3, cylinder 4, extrusion module 6, condenser 17, heating tube 24 and electric telescopic rod 25 are all equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they will not be repeated in the specification.

[0039] It is understood that this utility model is described through some embodiments, and as those skilled in the art will know, various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, modifications to these features and embodiments can be made to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
