Description

Technical Field

[0001] The utility model relates to the technical field of molds, and in particular to a glass fiber reinforced plastic grille mold. Background Art

[0002] At present, FRP grating molds have a profound technical background, and their research and development and application occupy an important position in modern industry. FRP grating molds are widely used in chemical industry, electric power, environmental protection and other fields due to their high strength, corrosion resistance, light weight and easy processing. With the advancement of science and technology, the manufacturing technology of FRP grating molds has been continuously improved, the mold design has become more precise, and the production efficiency has been greatly improved. At the same time, the deep-rooted concept of environmental protection has also promoted the green development of FRP grating molds, making them more in line with the requirements of sustainable development while meeting functional requirements.

[0003] In the prior art, there is a glass fiber reinforced plastic grille forming mold with an authorization announcement number of CN205969667U. The patent includes a base and a pouring area located above the base. A plurality of squares are arranged in an array in the pouring area. A push rod is arranged between the squares. The push rods can move up and down, and the length of the push rod exceeds the height of the square. In addition, a support plate is installed between the base and the pouring area. The support plate can also move up and down. One end of the push rod is fixed on the support plate to ensure that the push rod moves synchronously with the support plate. The base and the pouring area are also fixedly connected by a plurality of support rods to ensure the stability of the overall structure. The support plate can be moved up and down by the structure. The glass fiber reinforced plastic grille can be easily ejected by the push rod that can move up and down, which greatly improves the operating efficiency.

[0004] However, the patent has no cleaning device. During the working process of the mold, excess resin will flow onto the side wall of the mold or the ejector pin at the bottom of the lower mold. After the resin solidifies for a long time, it is difficult to clean. Long-term accumulation will seriously affect the use of the mold and make the molding quality poor when the mold is used again.

[0005] In the prior art, there is a glass fiber reinforced plastic grille forming mold with the authorization announcement number CN220280353U. The patent has multiple forming grooves evenly distributed to ensure the accurate forming of the grille. A cooling plate is installed at the bottom of the lower mold so that the fluid injected into the forming groove can be quickly cooled, thereby improving the forming processing efficiency of the glass fiber reinforced plastic grille. The bottom of the lower mold is also fixedly connected to a mounting plate, and an ejection mechanism is assembled at the top center of the mounting plate. After the grille is formed, this mechanism can quickly eject it, and at the same time, it can be quickly reset with the help of a reset ejector assembly, which simplifies the connection operation with the power mechanism and reduces power consumption.

[0006] However, this patent has no cleaning device, and the accumulation of excess resin will cause the surface of the mold to be uneven, making it difficult to obtain uniform resin distribution during the molding process of the product, increasing the difficulty of cleaning, and may cause damage to the mold bed.

[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] like Figure 1 to Figure 7 As shown, this embodiment proposes a glass fiber reinforced plastic grille mold, including a mold base 5 and a base 8, a plurality of modules 10 are welded inside the mold base 5, both sides of the mold base 5 are fixedly connected with cleaning boxes 4 by screws, and the two cleaning boxes 4 are slidably equipped with connecting blocks 11, one side of the connecting blocks 11 is welded with a cleaning plate 17, and the cleaning plate 17 is slidably assembled inside the cleaning box 4, and a plurality of support rods 7 are welded on the top of the base 8, and the outer circumferential surfaces of the plurality of support rods 7 are slidably assembled together.

[0030] Equipped with a support plate 6, three cylinders 9 are installed on the top of the base 8 and the bottom of the support plate 6, four sliding rods 3 are welded inside the cleaning box 4, and a pressure plate 1 is slidably installed on the outer circumference of the four sliding rods 3, and a clamping frame 2 and a rack plate 12 are respectively installed at the bottom of the pressure plate 1. A partition 31 is welded on the inner wall of the cleaning box 4, and the top ends of several support rods 7 are welded to the bottom of the mold base 5; a reciprocating screw is rotatably installed inside the cleaning box 4, and a gear 18 is movably sleeved on the outer circumference of the reciprocating screw 15, and the gear 18 is meshed with the rack plate 12. A number of circumferentially evenly distributed limiting holes 23 are opened inside the gear 18, and a limiting block 25 is slidably installed inside the reciprocating screw 15. Sliding blocks 16 are slidably installed on the outer circumferences of the two reciprocating screws 15, and the sliding blocks 16 and the cleaning plate 17 A connecting block 11 is welded together on the upper surface, a connecting rod 26 is welded inside the sliding block 16, a moving block 28 is installed at the bottom end of the connecting rod 26, two limit plates 29 are fixedly sleeved on the outer circumference of the reciprocating screw rod 15, and a synchronous belt 19 is installed together on the outer circumference of the two reciprocating screw rods 15. Through the arrangement of the cleaning plate 17 and the rack plate 12 and other structures, when the pressing plate 1 slides downward, the rack plate 12 slides downward, so that the gear 18 rotates to drive the reciprocating screw rod 15 to rotate, so that the cleaning plate 17 starts to reciprocate, and the cleaning plate 17 quickly cleans off the excess resin on the grinding seat 5 to ensure the cleanliness and flatness of the mold side surface, which helps to avoid product quality problems caused by resin accumulation. By regularly scraping off excess resin, the mold bed can be kept clean and unobstructed, reducing the maintenance and replacement costs caused by blockage or damage.

[0031] like Figure 2 As shown, a synchronous wheel 20 is fixedly sleeved on the outer circumference of each of the two reciprocating screw rods 15 , and a synchronous belt 19 is installed on the outer circumference of the two synchronous wheels 20 .

[0032] like Figure 1~Figure 2 As shown, a straight groove is provided on one side of the cleaning box 4, and the connecting block 11 is slidably connected inside the straight groove. Figure 1~Figure 2 As shown, four sliding holes are opened on the pressing plate 1, and the sliding rods 3 pass through the inside of the sliding holes.

[0033] like Figure 4~Figure 5 As shown, a circular groove 30 is opened inside the gear 18, the reciprocating screw 15 passes through the circular groove 30, a square groove 14 is opened inside the reciprocating screw 15, a part of the limit block 25 is slidably connected inside the square groove 14, and a return spring 24 is fixedly connected between the limit block 25 and the inner wall of the square groove 14.

[0034] like Figure 1 As shown, the support plate 6 is provided with a plurality of circular holes, and the support rods 7 pass through the inside of the circular holes.

[0035] like Figure 6 As shown, a reciprocating slide groove 27 is provided on the reciprocating screw rod 15 , and a moving block 28 is slidably connected inside the reciprocating slide groove 27 .

[0036] In this embodiment, the staff pours the resin into the mold base 5, and manually grinds it to make the resin evenly distributed on the mold base 5, and then presses the pressing plate 1 downward to form the grid;

[0037] Further, the pressing plate 1 starts to descend through the motor drive, and the rack plate 12 starts to move. Since the gear 18 and the rack plate 12 are meshed, the gear 18 starts to rotate along with the rack plate 12. When the gear 18 rotates, the reciprocating screw rod 15 is driven to rotate together, so that the sliding block 16 starts to move, and the cleaning plate 17 is driven to move synchronously through the connecting block 11, so that the cleaning plate 17 reciprocates in the cleaning box 4 to start cleaning. Due to the setting of the synchronous belt 19, the two reciprocating screw rods 15 rotate synchronously to complete the cleaning of both sides;

[0038] In addition, due to the setting of the curved surface on the limit block 25, the rack plate 12 descends, which can drive the reciprocating screw 15 to rotate. At the same time, when it rises, the circular groove 30 squeezes the curved surface of the limit block 25, so that the limit block 25 moves into the inside of the square groove 14, and does not drive the reciprocating screw 15 to move. The reset spring 24 is used to reset the limit block 25, and then the pressing plate 1 is lowered and the mold is re-engaged.

[0039] During molding, cleaning can be performed again. The gear 18 is restricted by two limit plates 29 so that the gear 18 will not be separated from the limit block 25 and the rack plate 12, thereby ensuring the stable operation of the device. The partition 31 is set so that the resin cleaned by the cleaning plate 17 falls on the partition 31 and accumulates at both ends of the box, which is convenient for the staff to carry out subsequent processing and simultaneously prevents the resin from falling on the reciprocating screw 15 and the synchronous belt 19 to affect the operation of the device.

[0040] Example 2

[0041] like Figure 1~Figure 3 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a plurality of connecting plates 22 are fixedly connected to the support plate 6 by screws, a plurality of fixing plates 21 are fixedly connected to the top of the connecting plate 22 by screws, a plurality of ejector pins 13 are fixedly connected to the top of the fixing plate 21 by screws, and the plurality of connecting blocks 11 and the fixing plate 21 are connected to the support plate 6 by setting structures such as the connecting block 11 and the fixing plate 21, and an ejector pin 13 is separately installed on each fixing plate 21, so that the overall structure is modularized, and the ejector pins 13 can be removed separately, so that maintenance personnel can quickly locate the problem and improve maintenance efficiency.

[0042] In this embodiment, the fixing plate 21 and the support plate 7 can be disassembled by screws, and the fixing plate 21 and the ejector pin 13 can also be disassembled by screws. Such a modular structure enables maintenance personnel to locate the problem more quickly when a demolding failure is found, thereby improving maintenance efficiency.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
