Description

Technical Field

[0001] The utility model relates to the technical field of plastic molding equipment, and particularly relates to a molding press device for producing fluoroplastic parts. Background Art

[0002] Fluoroplastics are known as the "king of plastics" due to their excellent chemical stability, corrosion resistance, and high temperature resistance. This kind of polymer material is hardly eroded by any chemical reagent and can maintain stable performance in extremely harsh environments. Therefore, it has been widely used in the fields of chemical industry, petroleum, pharmaceutical, electronics, etc. Fluoroplastics have an extremely low coefficient of friction and non-stick properties. Products such as seals and gaskets made of them can effectively prevent leakage and improve the sealing performance of equipment. They are widely used in valves, pumps, pipelines, etc., and have good high temperature resistance, excellent electrical insulation performance, and arc resistance, and are widely used in the field of electronics and electricity, such as wire and cable, insulating materials, etc.

[0003] However, there are also some problems in the production of fluoroplastic products by pressing in the prior art. The adhesion between fluoroplastics and the surface of the mold is strong, resulting in difficult demolding and affecting production efficiency. Secondly, a relatively high temperature is required during the molding of fluoroplastic products, and the cooling process takes a long time, reducing production efficiency and increasing production costs. Therefore, it is of great significance to develop a molding press device that is easy to demold and can quickly cool fluoroplastics for improving production efficiency. Summary of the Utility Model

[0007] The hydraulic mechanism includes a hydraulic column, and the lower end of the hydraulic column is fixedly connected with an upper mold.

[0008] The demolding component includes a lower mold, the lower mold is fixedly connected to the end face of the frame, a vertical pushing plate is slidably arranged at the bottom of the lower mold, a driving rod is fixedly installed at the lower end of the vertical pushing plate, a guiding rod is fixedly installed on the frame, a top plate is fixedly installed in the middle of the outer surface of the driving rod, the guiding rod penetrates through the top plate, and a spring is sleeved on the outer surface of the guiding rod, and the spring is located below the top plate.

[0009] A horizontal pushing component is arranged on one side of the lower mold, a conveyor belt is arranged on the other side of the lower mold, and a cooling component is arranged on the feeding path of the conveyor belt.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application. In addition, it should be understood that the specific implementation manners described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise stated, the orientation terms such as "upper", "lower", "left", and "right" usually refer to the upper, lower, left, and right in the actual use or working mode of the device, specifically the drawing direction in the drawings. The drawings are only for illustrative purposes and cannot be construed as a limitation of this patent; for better illustrating this embodiment, some components in the drawings will be omitted, enlarged, or reduced, and do not represent the dimensions of the actual product.

[0029] For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted. The drawings are only for illustrative purposes and cannot be construed as a limitation of this patent.

[0030] As shown in the attached Figures 1 - 6A molding device for the production of fluoroplastic parts as shown, which includes a frame 1, a hydraulic mechanism arranged on the frame 1, and a demolding component. The frame 1 is made of high-strength steel to ensure the stability of the device.

[0031] The hydraulic mechanism includes a hydraulic column 21, and a lower end of the hydraulic column 21 is fixedly connected to an upper mold 22. Since the specific structure of the hydraulic mechanism involved in this embodiment is well known to those skilled in the art, no further description is given in this specification.

[0032] The demolding component includes a lower mold 31. The lower mold 31 is fixedly connected to an end face of the frame 1. A vertical pushing plate 33 is slidably arranged at a bottom of the lower mold 31. A driving rod 34 is fixedly installed at a lower end of the vertical pushing plate 33. A guiding rod 32 is fixedly installed on the frame 1. A middle part of an outer surface of the driving rod 34 is fixedly installed with a top plate 341. The guiding rod 32 penetrates through the top plate 341, and a spring 35 is sleeved on an outer surface of the guiding rod 32. The spring 35 is located below the top plate 341.

[0033] A horizontal pushing component is arranged on one side of the lower mold 31, and a conveyor belt 46 is arranged on the other side of the lower mold. A cooling component is arranged on a feeding path of the conveyor belt 46; the horizontal pushing component can push materials into the conveyor belt, and the cooling component can cool the materials on the conveyor belt.

[0034] In some embodiments, the cooling component includes: a liquid storage tank 41, a water pump 42, and a water delivery pipe 43. An input end of the water pump 42 is communicated with the liquid storage tank 41, an output end of the water pump 42 is connected to the water delivery pipe 43, and the water delivery pipe 43 is also communicated with a spray nozzle 44.

[0035] In some embodiments, the cooling component further includes a water collecting hopper 47. The water collecting hopper 47 is arranged below the spray nozzle 44, and the water collecting hopper 47 is communicated with the liquid storage tank 41. The water collecting hopper 47 can effectively collect the coolant flowing down during the spray cooling process, preventing liquid waste and environmental pollution. The water collecting hopper 47 is communicated with the liquid storage tank 41, and the collected coolant can flow back into the liquid storage tank 41, and through recycling, the coolant is saved.

[0036] In some embodiments, heat dissipation fins 411 are arranged on an outer wall of the liquid storage tank 41. The heat dissipation fins 411 increase the surface area of the liquid storage tank 41, thereby improving the heat dissipation efficiency, and helping to more quickly reduce the temperature of the liquid in the liquid storage tank 41. Through effective heat dissipation, it is ensured that the temperature of the coolant remains stable during the circulation process, thereby improving the overall efficiency and stability of the cooling component.

[0037] In some embodiments, the cooling assembly further includes a cooling fan 45 disposed above the conveyor belt 46, and the cooling fan 45 is aligned with the heat dissipation fins 411. The cooling fan 45 can provide additional air flow to help the fluoroplastic parts on the conveyor belt 46 dissipate heat more quickly, while drying the residual coolant on the surface of the fluoroplastic parts to keep the fluoroplastic parts dry. Further, when there are no fluoroplastic parts on the conveyor belt 46, the cooling fan 45 is also in operation, driving the air flow below, thereby accelerating the heat exchange between the heat dissipation fins 411 and the air, and then quickly taking away the heat in the liquid storage tank 41, so as to achieve the purpose of cooling the coolant in the liquid storage tank 41.

[0038] In some embodiments, the frame 1 is fixedly connected with a pushing component, and the pushing component includes a linear displacement module 51 and a horizontal pushing plate 52. A slide rail 53 is connected between the lower mold 31 and the conveyor belt 46.

[0039] The linear displacement module 51 can be an electric push rod or a hydraulic push rod. The movable end of the linear displacement module 51 is fixedly connected with a horizontal pushing plate 52. The pushing component can realize the automatic pushing function, reduce manual intervention and improve production efficiency. The linear displacement module 51 can accurately control the moving distance and speed of the horizontal pushing plate 52 to ensure the consistency and accuracy of each pushing process and avoid errors caused by manual operation. The slide rail 53 is inclined to the upper end surface of the frame 1. Under the action of gravity, the fluoroplastic parts pushed out of the lower mold 31 slide onto the conveyor belt 46 through the slide rail 53.

[0040] The working principle of the present utility model is as follows:

[0041] When an operator uses it, first start the hydraulic component, and the hydraulic column 21 drives the upper mold 22 to move downward until the upper mold 22 and the lower mold 31 cooperate with each other to press the fluoroplastic into shape.

[0042] During the downward pressing process, the vertical pushing plate 33 moves downward under the downward pressure, and at the same time drives the driving rod 34 and the top plate 341 to move downward. During the downward movement of the top plate 341, the spring 35 is compressed.

[0043] After the fluoroplastic is compression molded, the hydraulic column 21 drives the upper mold 22 to move upward to separate the compression mold. Under the elastic force of the spring 35, the top plate 341 is pushed upward. The top plate 341 drives the driving rod 34 to push the vertical pushing plate 33 inside the lower mold 31 to move upward, and the fluoroplastic parts inside the lower mold 31 are pushed out vertically, thus completing the demolding of the fluoroplastic product.

[0044] Subsequently, the horizontal material pushing component is activated. The linear displacement module 51 drives the horizontal material pushing plate 52 to push the fluoroplastics parts horizontally. Under the action of gravity, the pushed fluoroplastics parts slide onto the conveyor belt 46 through the slide rail 53. Driven by the conveyor belt 46, the fluoroplastics parts are successively cooled by the spray nozzles 44 and the cooling fans 45. The coolant sprayed by the spray nozzles 44 conducts preliminary cooling on the fluoroplastics parts, while the cooling fans 45 further reduce the temperature of the fluoroplastics parts through the air flow to ensure their complete cooling and shaping, thus completing the entire production process.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
