Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber reinforced plastic processing, in particular to glass fiber reinforced plastic rapid solidification equipment. Background Art

[0002] Glass fiber reinforced plastic (FRP) is a fiber-reinforced plastic, also known as GFRP (glass fiber reinforced plastic). The application of FRP in high-speed rail is mainly reflected in many aspects, including but not limited to window frames, seats, passenger car wall panels, roof panels, floors, toilets, restrooms, commodes, berths, luggage racks, air conditioners, air ducts, etc. The reason why these components are suitable for manufacturing with FRP is that FRP has the characteristics of light weight and hardness, non-conductivity, stable performance, high mechanical strength, and corrosion resistance.

[0003] FRP products need to be cured and formed in molds during production. In the existing technology, in order to speed up the curing speed of FRP products, the mold is generally heated to speed up the curing speed of FRP. However, when all the mixed raw materials are poured into the mold, a large number of bubbles will be generated due to the reaction between the raw materials. The presence of bubbles will reduce the transparency, strength and weather resistance of the product, affect the thermal performance and optical properties, and make the cured FRP products fail to meet the use requirements. Therefore, it is necessary to redesign the FRP rapid curing equipment to address the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-5 The glass fiber reinforced plastic rapid curing equipment includes a base plate 1, the upper end surface of the base plate 1 is fixedly installed with a slide rod 3 through two support plates 2, and a slider 5 is slidably installed on the outer wall of the slide rod 3 through a limit mechanism. The limit mechanism includes a limit rod 4 fixedly installed between the two support plates 2, and the limit rod 4 slides through the slider 5. The limit rod 4 can limit the slider 5 so that the slider 5 can only move axially along the outer wall of the slide rod 3. The outer wall of the slider 5 is connected to the inner wall of one of the support plates 2 through an elastic mechanism. The elastic mechanism includes a spring 6 installed on the outer wall of the slide rod 3, and both ends of the spring 6 are elastically connected to the inner wall of the support plate 2 and the outer wall of the slider 5 respectively.

[0023] A placement plate 7 is fixedly installed on the upper end surface of the slider 5, a mold 8 is fixedly installed on the upper end surface of the placement plate 7, an extrusion block 9 is fixedly installed on the bottom wall of the placement plate 7, an extrusion groove is provided on the outer wall of the extrusion block 9, and a motor 11 is fixedly installed on the upper end surface of the base plate 1 through a first supporting mechanism. The first supporting mechanism includes a first supporting frame 10 fixedly installed on the upper end surface of the base plate 1, the motor 11 is fixedly installed on the bottom wall of the first supporting frame 10, and a cam 12 is fixedly installed on the outer wall of the output shaft of the motor 11.

[0024] Two connecting plates 13 are fixedly installed on the upper end surface of the base plate 1, and the inner walls of the two connecting plates 13 are fixedly connected to the semiconductor heater 15 through a telescopic mechanism. The telescopic mechanism includes an electric push rod 14 fixedly installed on the inner wall of the connecting plate 13, and the telescopic end of the electric push rod 14 is fixedly connected to the outer wall of the semiconductor heater 15. Since the semiconductor heater 15 uses semiconductor materials to generate heat, heat energy can be generated rapidly in a short time after power is turned on, thereby achieving the effect of rapid heating. This heating method also makes it possible to accurately control the heating temperature, so as to avoid problems such as overheating or too low temperature causing poor heating effect. An air cooler 17 is fixedly installed on the upper end surface of the base plate 1 through a second supporting mechanism. The second supporting mechanism includes a second support frame 16 fixedly installed on the upper end surface of the base plate 1, and the air cooler 17 is fixedly installed on the upper end surface of the second support frame 16. The outer wall of the outlet pipe of the air cooler 17 is fixedly mounted with a blowing pipe 18, and the outer wall of the blowing pipe 18 is provided with a blowing opening connected to the interior.

[0025] When the utility model is used, the mixed raw material can be poured into the mold 8, and then the motor 11 can drive the cam 12 to rotate. When the cam 12 is rotatable, it can contact the inner wall of the extrusion groove, thereby making the extrusion block 9 driven by force to drive the placement plate 7 to move, and the placement plate 7 then drives the slider 5 to slide on the outer wall of the slide bar 3 through the cooperation of the limit rod 4, and pulls the spring 6 during the sliding process. When the cam 12 contacts the inner wall of the extrusion groove, the slider 5 can drive the placement plate 7 to slide and reset under the elastic pull of the spring 6. When the cam 12 continues to rotate and intermittently contacts the inner wall of the extrusion groove, the placement plate 7 can drive the mold 8 to shake back and forth left and right through the elastic cooperation of the spring 6, so that the bubbles inside the mixed raw material can be eliminated by shaking, thereby preventing the bubbles from reducing the transparency, strength and weather resistance of the product and affecting the thermal performance and optical properties.

[0026] While the mixed raw materials are reacting and solidifying, the two electric push rods 14 can respectively drive the semiconductor heaters 15 on the same side to move, so that the two semiconductor heaters 15 can respectively fit with the outer walls on both sides of the mold 8, so that the two semiconductor heaters 15 can heat the outer walls of the mold 8. Through heat conduction, the mixed raw materials inside the mold 8 can be heated, thereby increasing the solidification and molding speed of the fiberglass reinforced plastics. When the heating and solidification are completed, the cold air blower 17 can blow cold air into the blowing pipe 18, and then the cold air can be blown out through the blowing opening inside the blowing pipe 18, thereby blowing and cooling the solidified fiberglass reinforced plastics, so that it can be easily removed from the mold 8.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
