Abstract
Description
Technical Field
[0001] This invention relates to the field of fiberglass grating processing technology, and more specifically, to a fiberglass grating production mold and production process for uniformly distributed fiberglass grating. Background Technology
[0002] Fiberglass grating is a type of plate-like material with many openings, made by using fiberglass as reinforcement and unsaturated polyester resin as the matrix, and processed through a special composite process. Fiberglass grating can be used as a structural material for floors, trench covers, platforms, ship decks, stairs, walkways, etc., in corrosive environments. It features corrosion resistance, flame retardancy, non-magnetic insulation, bright colors, and a variety of styles and forms to choose from.
[0003] Fiberglass grating has been produced in my country for many years, but to this day, the vast majority of production still relies on the most primitive manual methods. The production of fiberglass grating involves processes such as weaving, resin pouring, compaction and venting, and heat curing, all within a mold composed of small modules of the same size and spacing.
[0004] Among the processes involved in manufacturing fiberglass grating, wire weaving is a time-consuming step. Although automated wire weaving equipment has emerged in recent years, this process, whether done manually or mechanically, is always performed on a mold. This prevents other processes from being carried out during the wire weaving process, thus hindering the improvement of fiberglass grating production efficiency. Summary of the Invention
[0005] The purpose of this invention is to provide a mold and process for producing fiberglass grating with uniform material distribution, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, one objective of this invention is to provide a uniformly distributed fiberglass grating production mold, comprising a template and a punch disposed on the top of the template. The punch includes multiple transverse grooves arranged at intervals for the entry of fiberglass yarn and multiple longitudinal grooves arranged at intervals for the entry of fiberglass yarn. The transverse and longitudinal grooves respectively penetrate the boundary of the punch, giving the punch an open boundary. The edge of the template protrudes beyond the edge of the punch and forms a stop portion.
[0007] It also includes a detachable fabric piece disposed on top of the stop portion. When the fabric piece is at the top of the stop portion, it closes the open boundary of the punch. The fabric piece has a ring structure and is used to constrain the glass fiber yarn to correspond to the shape of the punch.
[0008] By pre-arranging the glass fiber yarn on the yarn piece and placing the yarn piece on top of the stop during the production process, the glass fiber yarn enters the transverse and longitudinal grooves.
[0009] As a further improvement to this technical solution, the sidewall of the fabric piece is provided with multiple through slots, the positions of which correspond to the horizontal and vertical slots; by the fabric thread moving back and forth in the through slots, the fabric piece restricts the shape of the glass fiber yarn to the shape of the corresponding punch by passing through the through slots.
[0010] As a further improvement to this technical solution, the fabric piece is a separable multi-layer structure, the through groove is provided on the side wall of each layer of fabric piece, and a sealing element is provided between two adjacent fabric pieces;
[0011] The shape of the seal corresponds to the shape of the groove;
[0012] When two adjacent fabric pieces are stacked, the sealing element will seal the groove located below.
[0013] As a further improvement to this technical solution, a gap is reserved between the outer ring of the punch and the inner ring of the fabric piece, and the width of the gap is not less than the width of the transverse groove or the longitudinal groove.
[0014] As a further improvement to this technical solution, the fabric piece includes a bottom ring at the bottom, a plurality of middle rings in the middle, and a top ring at the top;
[0015] The through groove is provided on the outer ring of the bottom ring and the middle ring, and extends through the top of the bottom ring and the middle ring;
[0016] The seal is located at the bottom of the top ring and the bottom of each middle ring;
[0017] When the middle ring is stacked on top of the bottom ring, or two middle rings are stacked, or the top ring is stacked on top of the middle ring, the seal enters the through groove and seals the through groove.
[0018] As a further improvement to this technical solution, the height of the sealing element is lower than the height of the groove. When the sealing element enters the groove, a gap is generated between the bottom of the sealing element and the bottom of the groove. The thickness of the gap is consistent with the thickness of the glass fiber yarn after being compressed and deformed, so as to fill the gap with the glass fiber yarn and seal the groove.
[0019] As a further improvement to this technical solution, the outer ring of the fabric piece is provided with a limiting groove.
[0020] As a further improvement to this technical solution, straight rods are provided at the four corners of the top of the template corresponding to the stop parts, and the top of the bottom ring, middle ring and top ring are all provided with through holes for the straight rods to slide through.
[0021] The outer rings of the bottom ring and the middle ring are provided with fastening rods that can be inserted into the holes, and the bottom ring and the middle ring are locked to the outer ring of the straight rod by the fastening rods.
[0022] As a further improvement to this technical solution, a blocking ring that can protrude from the top of the template is elastically provided inside the template, and the inner ring of the blocking ring is flush with the inner ring of the bottom ring.
[0023] The bottom of the straight rod is fixedly connected to a base plate, and a lead screw is rotatably provided between the template and the base. The outer ring of the lead screw is threadedly connected to a slider with an "I" shaped structure. The middle part of the slider passes through the base plate and is longitudinally slidably connected to the base plate.
[0024] A cam is provided above the base;
[0025] Both the cam and the lead screw are driven to rotate by a drive device.
[0026] The second objective of this invention is to provide a manufacturing process for a fiberglass grating production mold for uniform material distribution, comprising the following steps:
[0027] S1. Wrap the glass fiber yarn around the bottom ring and the middle ring in advance, and stack the wrapped bottom ring and middle ring according to their positional relationship;
[0028] S2. Place the bottom ring on top of the stop part, pour the mixed resin into the top of the punch, and scrape the resin into the horizontal and vertical grooves with a tool. At this time, the bottom ring blocks the resin with its own height, and the height of the resin in the horizontal and vertical grooves does not exceed the bottom height of the corresponding groove.
[0029] S3. Move the middle ring to the top of the bottom ring. At this time, the seal at the bottom of the middle ring enters the through groove and seals the through groove with glass fiber yarn. Continue to pour in resin and make sure that the height of the resin entering the horizontal and vertical grooves does not exceed the bottom height of the corresponding through groove.
[0030] S4. Repeat S2 and S3, and then place the top ring on top of the corresponding middle ring.
[0031] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0032] 1. In the production mold and process of the uniformly distributed fiberglass grating, the fabric pieces are detachably connected to the template, allowing the fabric pieces to be prefabricated at other workstations. In this way, during the production process, the prefabricated fabric pieces only need to be placed on the outer periphery of the mold, thereby reducing the number of steps workers need to take on the mold and improving the production efficiency of the fiberglass grating.
[0033] 2. In the production mold and process of the uniformly distributed fiberglass grating, by setting the template and the fabric piece to be detachable, the fabric piece can drive the fiberglass yarn to move in the transverse and longitudinal grooves. The force generated by the movement removes air bubbles in the resin and improves the strength of the fiberglass grating. Attached Figure Description

[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0050] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not 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 invention.
[0051] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.
[0052] One objective of this invention is to provide a production mold for fiberglass grating with uniform material distribution, such as... Figure 1 As shown, the mold includes a template 100 and a punch 101 disposed on the top of the template 100. The bottom of the template 100 is connected to a base 104, which supports the template 100 at a predetermined height. The predetermined height corresponds to the height required for manual operation, so as to facilitate manual operation on the top of the template 100.
[0053] like Figure 2As shown, the length and width of the template 100 are both greater than the length and width of the punch 101, that is, the edge of the template 100 protrudes beyond the edge of the punch 101, and the protruding part forms a stop part, which is used to support the fabric piece 110, which will be described in detail below.
[0054] like Figure 2 As shown, the punch 101 is composed of a plurality of punches arranged at even intervals. The punch 101 includes a plurality of transverse grooves 102 arranged at intervals for the glass fiber yarn 200 to enter and a plurality of longitudinal grooves 103 arranged at intervals for the glass fiber yarn 200 to enter. The transverse grooves 102 and longitudinal grooves 103 respectively penetrate the boundary of the punch 101, so that the punch 101 has an open boundary; the transverse grooves 102 and longitudinal grooves 103 intersect, and the groove widths of the transverse grooves 102 and longitudinal grooves 103 are the same.
[0055] In this embodiment, the transverse groove 102 and the longitudinal groove 103 are perpendicular to each other, and the groove direction of the transverse groove 102 is parallel to the longitudinal groove 103. Figure 2 In the X direction, the groove direction of the longitudinal groove 103 is parallel to... Figure 2 In the Y direction, this mold can produce fiberglass gratings with a minimum unit of square.
[0056] The aforementioned mold also includes a yarn-making component 110 for constraining the glass fiber yarn 200 into a shape corresponding to the punch 101. The yarn-making component 110 has a ring structure and is detachably disposed on top of the stop portion. When the yarn-making component 110 is on top of the stop portion, it closes the open boundary of the punch 101. Then, by pre-arranging the glass fiber yarn 200 on the yarn-making component 110 and placing the yarn-making component 110 on top of the stop portion during production, the glass fiber yarn 200 enters the transverse groove 102 and the longitudinal groove 103 to complete the yarn-making process.
[0057] like Figure 3 and Figure 4 As shown, the side wall of the fabric piece 110 is provided with a plurality of through grooves 115. The positions of the plurality of through grooves 115 correspond to the horizontal grooves 102 and the vertical grooves 103. By weaving the fabric back and forth in the through grooves 115, the fabric piece 110 restricts the shape of the glass fiber yarn 200 into a mesh shape (that is, corresponding to the shape of the punch 101) by the through grooves 115.
[0058] It should be understood that the mold also includes an ejection mechanism for ejecting the molded fiberglass grating and a heating mechanism for heating the resin. Both are existing technologies and will not be described in detail here.
[0059] In other words, by detachably connecting the fabric piece 110 to the template 100, the fabric piece 110 can be prefabricated at other workstations. In this way, during the production process, the prefabricated fabric piece 110 only needs to be placed on the outer periphery of the mold, thereby reducing the number of steps workers need to take on the mold and improving the production efficiency of fiberglass grating.
[0060] Taking a 40mm thick fiberglass grating as an example, to improve strength, approximately eight layers of fiberglass yarn 200 are laid during the production process. Therefore, in this embodiment, the yarn pieces 110 are also configured as separable multi-layer structures. Each layer of yarn piece 110 has a groove 115 on its sidewall, and a sealing element 116 is provided between adjacent yarn pieces 110. When adjacent yarn pieces 110 are stacked, the sealing element 116 seals the groove 115 located below. Thus, after stacking, because the groove 115 seals the sealing element 116, the multiple layers of yarn pieces 110 can close the open boundary of the punch 101. Simultaneously, after the yarn pieces 110 are stacked, the multiple layers of fiberglass yarn 200 can also be placed within the transverse groove 102 and longitudinal groove 103, thereby achieving multi-layer laying.
[0061] The outer ring of the fiberglass grating is usually closed. Therefore, when casting the resin material, a gap needs to be reserved between the outer ring of the punch 101 and the inner ring of the fabric piece 110. The width of this gap should not be less than the width of the transverse groove 102 or the longitudinal groove 103. (See details...) Figure 12 ,exist Figure 12 In the middle, the position of the cloth piece 110 is at the top of the stop part.
[0062] For ease of understanding, the multi-layered fabric piece 110 is described in detail in three parts. For example... Figure 4 As shown, the rings are a bottom ring 111, multiple middle rings 112, and a top ring 113. The outer rings of both the bottom ring 111 and the middle rings 112 have multiple through slots 115 extending through the top. These through slots 115 correspond to the horizontal slots 102 and the vertical slots 103. For more details, please refer to... Figure 2 The through groove 115 is provided at the ends of the transverse groove 102 and the longitudinal groove 103. In this way, combined with... Figure 7 and Figure 8 By winding the glass fiber yarn 200 around each slot 115 in a continuous "S" shape, the glass fiber yarn 200 can be wound into a mesh. At the same time, since the slot 115 corresponds to the ends of the transverse slot 102 and the longitudinal slot 103, when the bottom ring 111 and the middle ring 112 are placed on top of the stop, the glass fiber yarn 200 can be placed in the transverse slot 102 and the longitudinal slot 103.
[0063] In addition, the bottom of the top ring 113 and the bottom of each middle ring 112 are provided with a sealing element 116 whose shape corresponds to the through groove 115. When the middle ring 112 is stacked on top of the bottom ring 111, or when two middle rings 112 are stacked, or when the top ring 113 is stacked on top of the middle ring 112, the sealing element 116 can enter the through groove 115 and seal the through groove 115.
[0064] It is worth noting that, such as Figure 9 As shown, the height of the seal 116 is lower than the height of the groove 115. When the seal 116 enters the groove 115, a gap is created between the bottom of the seal 116 and the bottom of the groove 115. The thickness of this gap is the same as the thickness of the glass fiber yarn 200 after it is compressed and deformed. In this way, the gap is filled by the glass fiber yarn 200, thus achieving a seal on the groove 115.
[0065] exist Figure 4 In order to prevent the glass fiber yarn 200 from detaching from the outer ring of the yarn piece 110 during the winding process, this embodiment provides a limiting groove 114 on the outer ring of the yarn piece 110 (i.e., the bottom ring 111 and the middle ring 112). The limiting groove 114 is preferably a "V" shaped structure, and the height of the inner end of the limiting groove 114 is the same as the bottom height of the through groove 115. In this way, the limiting groove 114 has a limiting effect on the glass fiber yarn 200 during winding, thereby improving the stability of winding.
[0066] Furthermore, considering the potential for positional deviations during stacking, therefore, firstly... Figure 1 As shown, straight rods 120 are provided at the four corners of the top of the template 100 corresponding to the stop parts. The tops of the bottom ring 111, middle ring 112, and top ring 113 are all provided with through holes for the straight rods 120 to slide through. Then, as... Figure 5 As shown, the outer rings of the bottom ring 111 and the middle ring 112 are provided with fastening rods 121 that can be inserted into the through holes. The bottom ring 111 and the middle ring 112 are locked to the outer ring of the straight rod 120 by the fastening rods 121.
[0067] There are various locking methods, and this invention exemplifies two common methods: screw locking and plug locking. Figure 5 The specific structure of the screw lock is shown. Specifically, the fastening rod 121 is threadedly connected to the middle ring 112, and the straight rod 120 is clamped by the screw force to achieve the locking of the middle ring 112. Figure 6 The specific structure of the plug-in locking is shown. Specifically, multiple insertion holes for the fastening rod 121 are provided on the outer ring of the straight rod 120. At the same time, a spring is provided between the fastening rod 121 and the middle ring 112 to elastically connect the two. The middle ring 112 is locked by inserting the fastening rod 121 into the insertion hole on the outer ring of the straight rod 120.
[0068] It is worth noting that when fixing the starting end of the glass fiber yarn 200, it can be done as follows: Figure 8 As shown, the starting end of the glass fiber yarn 200 is placed into the part of the fastening rod 121 that enters the middle ring 112, so as to fix the starting end of the glass fiber yarn 200 by means of the fastening rod 121.
[0069] Combination Figure 10 The following will explain the process of using the mold in detail.
[0070] First, wind the glass fiber yarn 200 onto the bottom ring 111 and the middle ring 112. Then, stack the wound bottom ring 111 and the middle ring 112 according to their positional relationship, and then use perforations to constrain the bottom ring 111 and the middle ring 112 to the outer ring of the straight rod 120. Finally, cover the top ring 113 onto the top of the middle ring 112.
[0071] Next, the bottom ring 111 is unlocked using the fastening rod 121, at which point the bottom ring 111 moves down to the top of the stop portion. Then, the mixed resin is poured into the top of the punch 101, and the resin is scraped into the transverse groove 102 and the longitudinal groove 103 using a tool. At this time, the bottom ring 111 blocks the resin with its own height, and the height of the resin in the transverse groove 102 and the longitudinal groove 103 does not exceed the bottom height of the corresponding through groove 115. Then, the middle ring 112 is moved to the top of the bottom ring 111, at which point the sealing element 116 at the bottom of the middle ring 112 enters the through groove 115, and the through groove 115 is sealed by the glass fiber yarn 200. Resin is then poured in, ensuring that the height of the resin entering the transverse groove 102 and the longitudinal groove 103 does not exceed the bottom height of the corresponding through groove 115. The above steps are repeated, and finally, the top ring 113 is moved down to cover the top of the middle ring 112. Meanwhile, the height of the top ring 113 covering the top of the middle ring 112 is the same as the height of the punch 101.
[0072] Moreover, combined Figure 11 and Figure 13 As shown, the template 100 has an elastically designed (specifically, spring-loaded) retaining ring 105 that protrudes from the top of the template 100. The inner ring of the retaining ring 105 is flush with the inner ring of the bottom ring 111. The bottom of the straight rod 120 is fixedly connected to a base plate 122. A lead screw 123 is rotatably connected between the template 100 and the base 104. The outer ring of the lead screw 123 is threadedly connected to a slider 124. The middle part of the slider 124 passes through the base plate 122 and slides longitudinally with the base plate 122. The slider 124 has an "I" shaped structure. A cam 125 is provided above the base 104. Both the cam 125 and the lead screw 123 are driven to rotate by a motor.
[0073] After resin is poured, the motor drives the lead screw 123 to rotate. The rotation of the lead screw 123 causes the slider 124 to move downward, which in turn causes the base plate 122 to move downward, and the base plate 122 to move downward, which in turn causes the straight rod 120 to move downward. When the base plate 122 moves to the outer ring of the cam 125, the bottom ring 111 and the middle ring 112 are locked to the straight rod 120. Then, the motor drives the cam 125 to drive the base plate 122 to reciprocate up and down. The base plate 122 achieves its own reciprocating motion by sliding up and down the outer ring of the slider 124. The base plate 122 drives the straight rod 120 to reciprocate. The straight rod 120 drives the glass fiber yarn 200 to move at a high frequency in the transverse groove 102 and the longitudinal groove 103 through the bottom ring 111 and the middle ring 112, thereby removing air bubbles from the resin in the transverse groove 102 and the longitudinal groove 103 through the glass fiber yarn 200. Furthermore, when the bottom ring 111 moves upward, the blocking ring 105 moves upward via a spring to prevent the resin in the transverse groove 102 and the longitudinal groove 103 from flowing out through the bottom of the bottom ring 111.
[0074] In other words, by setting the template 100 and the fabric piece 110 to be detachable, the fabric piece 110 can drive the fiberglass yarn 200 to move in the transverse groove 102 and the longitudinal groove 103, and use the force generated by the movement to remove air bubbles in the resin, thereby improving the strength of the fiberglass grating.
[0075] The second objective of this invention is to provide a manufacturing process for a fiberglass grating production mold for uniform material distribution, comprising the following steps:
[0076] S1. Wrap the glass fiber yarn 200 around the bottom ring 111 and the middle ring 112 in advance, and stack the wrapped bottom ring 111 and middle ring 112 according to their positional relationship;
[0077] S2. Place the bottom ring 111 on top of the stop part, pour the stirred resin into the top of the punch 101, and scrape the resin into the horizontal groove 102 and the vertical groove 103 with a tool. At this time, the bottom ring 111 blocks the resin with its own height, and the height of the resin in the horizontal groove 102 and the vertical groove 103 does not exceed the bottom height of the corresponding through groove 115.
[0078] S3. Move the middle ring 112 to the top of the bottom ring 111. At this time, the seal 116 at the bottom of the middle ring 112 enters the groove 115 and seals the groove 115 with glass fiber yarn 200. Then continue to pour in resin and make sure that the height of the resin entering the transverse groove 102 and the longitudinal groove 103 does not exceed the bottom height of the corresponding groove 115.
[0079] S4. Repeat S2 and S3, and then place the top ring 113 on top of the corresponding middle ring 112.
[0080] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
