Description

Technical Field

[0001] This utility model relates to the technical field of fiberglass production equipment, specifically to a molding device for fiberglass. Background Technology

[0002] Fiberglass generally refers to reinforced plastics made by reinforcing unsaturated polyester, epoxy resin and phenolic resin matrices with glass fiber, and using glass fiber or its products as reinforcing materials. It is called glass fiber reinforced plastic, commonly known as fiberglass. It is lightweight and hard, non-conductive, stable in performance, high in mechanical strength, low in recyclability, and corrosion resistant. It is often used in the chemical industry.

[0003] A Chinese patent describes a molding equipment for producing fiberglass reinforced plastic (FRP). The equipment includes a base with guide pillars fixedly connected to its upper perimeter and a top plate fixedly connected to the top of each guide pillar. However, the equipment lacks a mechanism for heating or cooling the lower mold. If the mold temperature is too low when the raw material is poured into the lower mold, the material may solidify prematurely, potentially leading to product defects or performance degradation, thus affecting the equipment's production quality. Furthermore, the lack of a cutting mechanism means that after molding, some raw material may overflow the mold, requiring secondary cutting and processing, which is detrimental to production efficiency.

[0004] In the prior art, when the raw material is poured into the lower mold before stamping, the mold temperature is low, which may cause the raw material to solidify prematurely, affecting the product quality. During stamping, some raw material may splash out of the mold, which may cause injury to the workers. After stamping, the excess part of the top of the product needs to be cut off and some raw material remaining on the mold surface needs to be cleaned, which may affect the production efficiency of the equipment. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a molding equipment for fiberglass, which solves the problem of premature solidification of raw materials due to the inability to preheat the lower mold in the prior art. By setting a square baffle to block splashed raw materials, the safety of the equipment is improved. By setting a cutter with adjustable height and position to cut off excess material on the mold surface or the top of the product, the technical problem of needing secondary processing is solved.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0027] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

[0030] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-3 As shown, this invention illustrates a molding device for fiberglass reinforced plastics according to one embodiment of the present invention, comprising: a base plate 1, with cylinders 3 fixedly connected to the four corners of the top of the base plate 1, a top plate 2 fixedly connected to the top of the cylinders 3, a mounting block 4 fixedly connected to the middle of the top of the base plate 1, and a control panel 9 fixedly connected to the front end of the base plate 1; the control panel 9 drives the four sets of cylinders 3 to move up and down synchronously, thereby engaging the upper mold 10 and the lower mold 11 to complete the molding process;

[0033] A square baffle 18 is slidably connected to the mounting block 4, and a pipe 21 is fixedly connected inside the mounting block 4. The pipe 21 is evenly installed around the lower mold 11. By setting the pipe 21 on the mounting block 4, the pipe 21 is made of high temperature resistant material and will not deform due to the temperature rise of the mounting block 4.

[0034] The base plate 1 has two sets of sliding grooves 13, and a reciprocating screw 14 is installed on each set of sliding grooves 13. A clamping mechanism 8 is threadedly connected to each set of reciprocating screw 14. One end of each set of reciprocating screw 14 passes through the base plate 1 and is fixedly connected to a synchronous wheel 16. By rotating the reciprocating screw 14, the clamping mechanism 8 is driven to reciprocate along the surface of the reciprocating screw 14.

[0035] A water inlet pipe 5 is fixedly connected to one side of the mounting block 4, and a water outlet pipe 6 is fixedly connected to the other side of the mounting block 4. One end of the pipe 21 is fixedly connected to the water inlet pipe 5, and the other end of the pipe 21 is fixedly connected to the water outlet pipe 6. By setting the water inlet pipe 5, coolant is transported to the pipe 21, allowing the coolant to flow on the pipe 21 and be discharged through the water outlet pipe 6. After cooling, it is transported back to the pipe 21 to cool the lower mold 11, which helps to accelerate the cooling and shaping of the fiberglass and improves the production efficiency of the equipment.

[0036] The mounting block 4 has a limiting groove 19, which is slidably connected to the square baffle 18. Two sets of electric telescopic rods 20 are fixedly connected to the mounting block 4. The two sets of electric telescopic rods 20 are symmetrically arranged, and the top ends of the two sets of electric telescopic rods 20 are fixedly connected to the square baffle 18. The two sets of electric telescopic rods 20 are electrically connected to the control panel 9. The control panel 9 controls the electric telescopic rods 20 so that when the equipment is pressurized and shaped, the electric telescopic rods 20 are driven in advance, causing the square baffle 18 to slide out of the mounting block 4 along the limiting groove 19. The length and width of the square baffle 18 are both greater than those of the upper mold 10 and the lower mold 11. The square baffle 18 effectively prevents fiberglass from splashing during the molding process of the upper mold 10 and the lower mold 11.

[0037] A heating mechanism 12 is fixedly connected to the base plate 1. The heating mechanism 12 is electrically connected to the control panel 9. The top of the heating mechanism 12 is fixedly connected to the mounting block 4. The mounting block 4 is made of a material with high thermal conductivity. The heating mechanism 12 includes a ceramic panel, a main control circuit board, a power supply circuit, a furnace coil, a cooling fan, a heat sink, a temperature sensor, and other auxiliary components. The heating mechanism 12 is driven by the control panel 9 to heat the mounting block 4 and preheat the lower mold 11. This helps to prevent the fiberglass from cooling before molding, which could lead to product defects or performance degradation.

[0038] For example, such as Figure 3 As shown, the electric telescopic rod 20 is controlled via the control panel 9, so that during the pressure setting process, the electric telescopic rod 20 is driven in advance, causing the square baffle 18 to slide along the limiting groove 19 and push out the mounting block 4. The length and width of the square baffle 18 are both greater than those of the upper mold 10 and the lower mold 11. The square baffle 18 effectively prevents fiberglass from splashing during the molding process of the upper mold 10 and the lower mold 11, which helps protect the health of the workers and reduces the probability of safety accidents. The heating mechanism 12 driven by the control panel 9 heats the mounting block 4 and preheats the lower mold 11, which helps prevent the fiberglass from cooling before molding and improves the production quality of the equipment.

[0039] like Figures 1-5As shown, this invention illustrates a molding device for fiberglass in another embodiment. The clamping mechanism 8 includes a slider 803 slidably connected to a groove 13. An electric push rod 802 is fixedly connected to the top of the slider 803, and a U-shaped clamping block 801 is fixedly connected to the top of the electric push rod 802. A threaded rod 804 is threadedly connected to the U-shaped clamping block 801, and a clamping plate 805 is rotatably connected to the bottom of the threaded rod 804 through the U-shaped clamping block 801. The clamping plate 805 is slidably connected to the U-shaped clamping block 801. By rotating the threaded rod 804, the clamping plate 805 slides along the U-shaped clamping block 801, fixing the cutter 7. By setting the electric push rod 802 to drive the U-shaped clamping block 801 to rise and fall, the cutter 7 is aligned with the top of the lower mold 11, cutting the fiberglass overflowing from the mold.

[0040] An electric motor 15 is fixedly connected to one end of the base plate 1. One end of the electric motor 15 is fixedly connected to one of the sets of reciprocating lead screws 14. A synchronous belt 17 is sleeved on the outside of the synchronous pulley 16. A cutter 7 is installed on the clamping mechanism 8. By driving the electric motor 15 to rotate, one of the sets of reciprocating lead screws 14 is driven to rotate. The rotation of the reciprocating lead screw 14 drives the synchronous pulley 16 to rotate. The rotation of the synchronous pulley 16 drives the synchronous belt 17 to rotate, so that the two sets of synchronous belts 17 rotate synchronously.

[0041] The mounting block 4 is fixedly connected to the lower mold 11 by bolts, and the bottom center of the top plate 2 is fixedly connected to the upper mold 10 by bolts. The upper mold 10 and the lower mold 11 are set in correspondence. The upper mold 10 and the lower mold 11 are replaceable, which helps to improve the practicality of the equipment.

[0042] For example, such as Figure 5 As shown, rotating the threaded rod 804 causes the clamping plate 805 to slide along the U-shaped clamping block 801, fixing the cutter 7. An electric push rod 802 drives the U-shaped clamping block 801 to rise and fall, making the cutter 7 the same height as the top of the lower mold 11, cutting the fiberglass overflowing from the mold. Driving the electric motor 15 rotates one set of reciprocating lead screws 14, which in turn rotates the synchronous pulley 16, which in turn rotates the synchronous belt 17, causing both sets of synchronous belts 17 to rotate synchronously.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
