To simplify the disclosure of the embodiments of the present invention, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the embodiments of the present invention. In addition, the embodiments of the present invention may repeat reference numerals and / or reference letters in different examples. This repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0037] See Figure 1As shown in the figure, this embodiment provides a mold for manufacturing fiberglass grids, which includes a bottom plate 1 and a punch assembly 2 protruding from the bottom plate 1. The punch assembly 2 is composed of a plurality of convex blocks arranged at equal intervals. The punch assembly 2 includes a plurality of first grooves 3 arranged at intervals in sequence and used for reciprocating wire laying along the groove, and a plurality of second grooves 4 arranged at intervals in sequence and used for reciprocating wire laying along the groove. The first grooves 3 and the second grooves 4 respectively penetrate the boundary of the punch assembly 2, so that the punch assembly 2 has an open boundary; the first grooves 3 and the second grooves 4 intersect, and the groove widths of the first grooves 3 and the second grooves 4 are the same.

[0038] In this embodiment, the first grooves 3 and the second grooves 4 are perpendicular to each other. The groove direction of the first grooves 3 is parallel to Figure 1 the X direction in Figure 1 and the groove direction of the second grooves 4 is parallel to the Y direction in, and the mold can manufacture fiberglass grids with the smallest unit being a square.

[0039] The above-mentioned mold for manufacturing fiberglass grids further includes a wire winding and pressing assembly located outside one end of the punch assembly 2 along the wire laying direction, and a clamping and pressing assembly located outside the other end of the punch assembly 2 along the wire laying direction. There are two sets of wire winding and pressing assemblies and clamping and pressing assemblies respectively. One set of wire winding and pressing assemblies and clamping and pressing assemblies are respectively located at both ends of the punch assembly 2 along the groove direction of the first grooves 3, and the other set of wire winding and pressing assemblies and clamping and pressing assemblies are respectively located at both ends of the punch assembly 2 along the groove direction of the second grooves 4.

[0040] The above-mentioned wire winding and pressing assembly includes a wire winding column 5 protruding from the bottom plate 1 and used for wire winding, and a first pressing mechanism (not shown in the figure) for pressing the wire on the wire winding column 5 downward. In this embodiment, the wire winding column 5 is aligned with the corresponding first grooves 3 along its groove direction or the corresponding second grooves 4 along its groove direction, and the fiberglass used for reciprocating wire laying along the groove direction of the first grooves 3 or the second grooves 4 bypasses it.

[0041] The wire winding column 5 is used to limit the turning point of the reciprocating wire laying fiberglass. Its advantages are as follows:

[0042] It enables the fiberglass to realize reciprocating wire laying, avoiding poor uniformity of the manufactured fiberglass grids caused by relying on the convex blocks at the edge for limiting;

[0043] It enables the first pressing mechanism to press the fiberglass from the outside of the punch assembly 2, and the thickness of each layer of the manufactured glass grid is the same and the layering is obvious;

[0044] Since the wire winding column 5 is located outside the punch assembly 2, cutting off this redundant part from the manufactured glass grid will not only not affect the quality of the glass grid itself, but also effectively ensure the overall quality of the glass grid.

[0045] The above clamping and pressing assembly includes a clamping mechanism disposed on the bottom plate 1 for clamping the initial end and / or the return end of the wire, and a second pressing mechanism for pressing the initial end and the return end of the wire downward simultaneously. In this embodiment, the clamping mechanism includes a clamping device 7 disposed on the bottom plate 1. The clamping device 7 is a clamping cylinder and is located outside the second pressing mechanism.

[0046] With this arrangement, when the wire laying mechanism lays the wire on the mold, the initial end of the glass fiber is clamped by the clamping mechanism. When the glass fiber turns back, the initial end and the return end of the glass fiber are pressed downward simultaneously by the second pressing mechanism. The initial end and the return end are located on the same side of the punch assembly 2. Since the second pressing mechanism is located outside the punch assembly 2, cutting off this redundant part from the obtained glass grid will not only not affect the quality of the glass grid itself, but also effectively ensure the overall quality of the glass grid.

[0047] By respectively arranging a first pressing mechanism and a second pressing mechanism on the outer sides of both ends of the punch assembly along the wire laying direction, the two are respectively used to press the two ends of the wire downward during the wire laying process, so that each layer of glass fiber is evenly laid and has the same thickness. The obtained fiberglass grid has obvious overall stratification and relatively good quality.

[0048] The first pressing mechanism includes a first pressing piece 6 and a first driving device (not shown in the figure) disposed on the bottom plate 1 for driving the first pressing piece 6 to press the wire downward. Refer to Figure 2 As shown, a limiting hole 61 for the wire winding column 5 to pass upward through is formed on the first pressing piece 6. The limiting hole 61 is matched with the shape of the wire winding column 5 so that the turning-back end of the glass fiber can be pressed downward through the first pressing piece 6.

[0049] Refer to Figure 5 As shown, a ring-shaped first wire guiding groove 63 is formed by the bottom of the first pressing piece 6 being recessed upward. The first wire guiding groove 63 opens toward the corresponding first groove 3 or second groove 4. The arrow indicates the running direction of the glass fiber entering the first wire guiding groove 63. Since the glass fiber has a certain thickness, the glass fiber wound around the wire winding column 5 is accommodated by the first wire guiding groove 63, and the glass fiber is pressed downward by the top groove bottom surface of the first wire guiding groove 63.

[0050] In this embodiment, the first driving device is a first rotary cylinder. A first pressing block is provided on the extending end of the first rotary cylinder. A first through hole 62 for the first pressing block to pass upward through and then press downward after rotation is also formed on the first pressing piece 6. The first through hole 62 is matched with the shape of the first pressing block.

[0051] In this embodiment, there are two groups of first rotating cylinders, and the orientations of the corresponding two groups of first pressing blocks at the pressing position are different, which are perpendicular to each other in this embodiment. Two groups of first through holes 62 are formed in the first pressing sheet 6, and the orientations of the two groups of first through holes 62 are the same. When the number of each group of first rotating cylinders is greater than or equal to two, the two groups of first rotating cylinders are arranged alternately one by one along the X direction or the Y direction.

[0052] Among the multiple first pressing sheets 6 (ten in this embodiment) used for successively stacking and sleeving on the wire winding column 5, the orientations of the first through holes 62 of two adjacent first pressing sheets 6 are different, which are perpendicular to each other in this embodiment. One group of first rotating cylinders is used to press the odd-numbered first pressing sheets 6, and the other group of first rotating cylinders is used to press the even-numbered first pressing sheets 6.

[0053] In this embodiment, there are two first rotating cylinders in each group. The orientations of the four first pressing blocks at the initial position are respectively "-", "|", "-", "|"; in the first first pressing sheet 6, the orientations of the four first through holes 62 are respectively "-", "-", "-", "-", and in the second first pressing sheet 6, the orientations of the four first through holes 62 are respectively "|", "|", "|", "|"; the orientations of the four first through holes 62 in the third first pressing sheet 6 are the same as those in the first one, and the orientations of the four first through holes 62 in the fourth first pressing sheet 6 are the same as those in the second one, and so on.

[0054] When the first first pressing sheet 6 is pressed downward, the first rotating cylinder with the first pressing block facing "-" does not move; when the first rotating cylinder with the first pressing block facing "|" rises, it first rotates the first pressing block so that it passes upward through the corresponding first through hole 62 with the orientation "-", and then when the first rotating cylinder descends, it rotates the first pressing block again so that it presses the first first pressing sheet 6 downward with the orientation "|";

[0055] When the second first pressing sheet 6 is pressed downward, the first rotating cylinder with the first pressing block facing "|" does not move; when the first rotating cylinder with the first pressing block facing "-" rises, it first rotates the first pressing block so that it passes upward through the corresponding first through hole 62 with the orientation "|", and then when the first rotating cylinder descends, it rotates the first pressing block again so that it presses the second first pressing sheet 6 downward with the orientation "-".

[0056] Through this setting, in continuous wire laying production, not only the pressing duration and pressing effect of the first rotating cylinder on the folded end of the glass fiber through the first pressing sheet 6 are ensured, but also the continuous wire laying and wire pressing are ensured, improving the production efficiency.

[0057] The second pressing mechanism includes a second pressing sheet 8 and a second driving device 9 arranged on the bottom plate 1 and used to drive the second pressing sheet 8 to press the wire downward.

[0058] SeeFigure 6 As shown, the bottom of the second pressing plate 8 is recessed upward to form a linear second wire groove 82, and the second wire groove 82 passes through the second pressing plate 8 along its own groove direction. Since the glass fiber entering the second wire groove 82 through the corresponding first groove 3 or second groove 4 has a certain thickness, the glass fiber is accommodated by the second wire groove 82, and the top groove bottom surface of the second wire groove 82 presses the glass fiber downward.

[0059] In this embodiment, the second driving device 9 is a second rotary cylinder, and a second pressing block 10 is provided on the extended end of the second rotary cylinder. Figure 3 As shown, the second pressing sheet 8 is further provided with a second through hole 81 for being extended upward by the second pressing block 10 and pressed downward after being rotated, and the second through hole 81 matches the shape of the second pressing block 10 .

[0060] In this embodiment, there are two groups of second rotary cylinders, and the corresponding two groups of second pressing blocks 10 have different directions at the pressing position, and in this embodiment, they are perpendicular to each other. Two groups of second through holes 81 are opened on the second pressing sheet 8, and the two groups of second through holes 81 have the same direction. When the number of each group of second rotary cylinders is greater than or equal to two, the two groups of second rotary cylinders are alternately arranged one by one along the X direction or the Y direction.

[0061] Among the multiple second pressing sheets 8 (ten in this embodiment) used for sequentially stacking the wire, the second through holes 81 of two adjacent second pressing sheets 8 are oriented in different directions, and in this embodiment, they are perpendicular to each other. One group of second rotary cylinders is used to press the odd-numbered second pressing sheets 8, and the other group of second rotary cylinders is used to press the even-numbered second pressing sheets 8.

[0062] In this embodiment, each group of second rotating cylinders has two, and the orientations of the four second pressure blocks 10 in the initial positions are respectively "—", "丨", "—", "丨"; in the first second pressing plate 8, the orientations of the four second through holes 81 are respectively "—", "—", "—", "—", and in the second second pressing plate 8, the orientations of the four second through holes 81 are respectively "丨", "丨", "丨", "丨", "丨"; the orientations of the four second through holes 81 in the third second pressing plate 8 are the same as those in the first plate, and the orientations of the four second through holes 81 in the fourth second pressing plate 8 are the same as those in the second plate, and so on.

[0063] The pressing process of the second rotating cylinder on the odd-numbered second pressing plates 8 and the even-numbered second pressing plates 8 refers to the description of the pressing process of the first rotating cylinder on the odd-numbered first pressing plates 6 and the even-numbered first pressing plates 6.

[0064] The above-mentioned mold for preparing fiberglass grids further includes peripheral baffles 11 protruding from the bottom plate 1 and located outside the two ends of the punch assembly 2 along the wire laying direction. The peripheral baffles 11 are partitioned along the groove direction of the corresponding first groove 3 or the second groove 4, and the peripheral baffles 11 are located inside the corresponding wire winding posts 5. The interval between the peripheral baffle 11 and the outermost convex block corresponding to it is the groove width of the first groove 3 or the second groove 4, and wire winding posts 5 are also provided outside the grooves at both ends. Through this setting, on the premise of ensuring the quality of the fiberglass grids, the part of the fiberglass grids to be cut can be reduced (that is, the formed part inside the peripheral baffle 11 can be used as the product boundary and does not need to be cut, only the formed parts between the peripheral baffles 11 and outside the peripheral baffles 11 need to be cut), the material utilization rate is improved, and the widths of the sides of the fiberglass grid product arranged along the X direction are the same after cutting off the convex parts, and the widths of the sides arranged along the Y direction are also the same. Since the peripheral baffle 11 is partitioned by the first groove 3 or the second groove 4 as the boundary of the product, the peripheral baffle 11 constitutes an open boundary of the mold.

[0065] There are four peripheral baffles 11 (the peripheral baffles 11 on one side of the punch assembly 2 are collectively referred to as one piece) and they surround the outside of the punch assembly 2. See Figure 4 As shown, the bottom of the peripheral baffle 11 is higher than the bottom of the punch assembly 2, and there is a height difference d between them. Through this setting, when injecting the bottom glue, the leakage of the bottom glue can be avoided.

[0066] The above-mentioned mold for preparing fiberglass grids further includes side plates 12 protruding from the bottom plate 1 and located outside the peripheral baffles 11. In this embodiment, there are four side plates 12 and they surround the outside of the peripheral baffles 11. For the side plates 12 located outside the second pressing piece 8, in order to facilitate wire laying, they are partitioned along the groove direction of the corresponding first groove 3 or the second groove 4.

[0067] See Figure 4 As shown, the side plate 12 has an inner inclined surface 121 that slopes downward and inwardly close to the peripheral baffle 11.

[0068] One side of the first pressing piece 6 close to the inner inclined surface 121 has a first inclined surface that matches it, so that the first pressing piece 6 can press against the corresponding peripheral baffle 11 during the downward pressing process, ensuring the consistency and pressing effect of wire pressing.

[0069] One side of the second pressing piece 8 close to the inner inclined surface 121 has a second inclined surface that matches it, so that the second pressing piece 8 can press against the corresponding peripheral baffle 11 during the downward pressing process, ensuring the consistency and pressing effect of wire pressing.

[0070] The working process of this embodiment is specifically described as follows:

[0071] a. Uniformly inject glue into the first groove 3 and the second groove 4 of the punch assembly 2;

[0072] b. Then, first perform a reciprocating wire laying along the X direction on all the first grooves 3 once (the number of wires laid in a single pass is three), and then perform a reciprocating wire laying along the Y direction on all the second grooves 4 once (the number of wires laid in a single pass is three);

[0073] Then, first press down the two ends of the fiberglass respectively through the first pressing piece 6 and the second pressing piece 8 at both ends, and then press down the fiberglass evenly distributed in the first groove 3 and the second groove 4 through the pressing device;

[0074] c. Alternately repeat a and b several times, and finally uniformly inject top glue into the first groove 3 and the second groove 4 of the punch assembly 2;

[0075] d. Heat and cure and then demold;

[0076] e. Cut off the redundant parts on the periphery of the fiberglass grating.

[0077] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention. The purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it, and it cannot be used to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
