Description

Technical Field

[0001] This invention relates to the field of mold processing technology, and more specifically, to a fiberglass shield mold. Background Technology

[0002] Traditional fiberglass molds mostly use a single upper and lower mold structure. The upper and lower molds are directly separated after pressing and molding, and demolding is achieved by the elasticity of the product or slight mechanical assistance (such as knocking).

[0003] The aforementioned demolding methods not only easily damage the product but also significantly reduce production efficiency. Operators need to spend extra time and effort manually demolding, which not only increases labor costs but also affects the continuity of the production line and overall efficiency. Summary of the Invention

[0004] This invention provides a fiberglass shield mold to solve the problem of low demolding efficiency caused by manual demolding, which is commonly used in the prior art.

[0005] This invention provides a fiberglass shield shell mold, which has a closed mold state and a closed mold state arranged opposite to each other. The fiberglass shield shell mold includes: a base plate; an upper mold and a lower mold. The lower mold is disposed on the base plate, and the upper mold is movably disposed above the lower mold to be closer to or farther away from the lower mold. The side of the upper mold facing the lower mold has a first extrusion surface, and the side of the lower mold facing the first extrusion surface has a second extrusion surface. The second extrusion surface is used to place the workpiece to be processed. When the fiberglass shield shell mold is in the closed mold state, the first extrusion surface and the second extrusion surface cooperate to extrude the workpiece. The demolding component includes a drive component, a movable plate, and at least one first ejector. The movable plate is movably disposed between a base plate and a lower die. One end of the first ejector is hinged to the movable plate, and the other end of the first ejector passes through the lower die. The drive component has a fixed end and a movable end disposed opposite to each other. The movable end is movable relative to the fixed end. The fixed end is disposed on the side of the movable plate away from the base plate. The movable end passes through the movable plate and is driven to connect with the base plate to drive the movable plate to move relative to the lower die, thereby driving the first ejector to move to protrude from the surface of the second extrusion surface.

[0006] Furthermore, the first ejector includes: a support, mounted on the movable plate; multiple support rods, one end of which is hinged to the support, and the other end of which passes through the lower mold, the support rods being inclined from the edge of the movable plate to the center of the lower mold; and an ejector block, located on the side of the second extrusion surface facing the first extrusion surface, the ends of the multiple support rods away from the movable plate being connected to the ejector block respectively. When the fiberglass shield mold is in the closed state, the ejector block is flush with the second extrusion surface; when the fiberglass shield mold is in the open state, the ejector block protrudes from the second extrusion surface.

[0007] Furthermore, the fiberglass shield mold includes multiple first ejector parts and multiple second ejector parts. The second extrusion surface has a first edge and a second edge that are arranged opposite to each other along the first direction. Multiple ejector blocks are respectively arranged along the first edge and the second edge along the second direction. The first direction and the second direction have an angle. One end of the second ejector part is fixedly connected to the movable plate, and the other end of the second ejector part passes through the lower mold. The multiple second ejector parts are distributed at intervals along the first direction.

[0008] Furthermore, the driving component includes: a cylinder body, which is disposed on the side of the movable plate away from the base plate and located on the outer periphery of the lower mold, with the bottom end of the cylinder body fixedly connected to the movable plate to form a fixed end; and a piston rod, which is movable relative to the cylinder body, with the end of the piston rod away from the cylinder body fixedly connected to the base plate to form a movable end.

[0009] Furthermore, the movable plate includes a first movable plate and a second movable plate that fit together. The first movable plate is located close to the lower mold. The cross-sectional areas of the bottom plate, the second movable plate, and the first movable plate decrease sequentially. When the fiberglass shield shell mold is in the closed state, the first movable plate, the second movable plate, and the bottom plate fit together in sequence. The cylinder is located on the second movable plate and is located in the area outside the projection of the first movable plate on the second movable plate.

[0010] Furthermore, a guide rod is provided on the side of the base plate facing the movable plate, and a guide sleeve is provided on the movable plate. The extension direction of the guide sleeve is the same as the movement direction of the movable plate. The guide rod and the guide sleeve are inserted and matched to guide the movement of the movable plate.

[0011] Furthermore, the upper mold has a first mating surface on the side facing the lower mold, and the first mating surface surrounds the outer periphery of the first extrusion surface. The lower mold has a second mating surface on the side facing the first mating surface, and the second mating surface surrounds the outer periphery of the second extrusion surface. The fiberglass shield mold includes a first pressure-bearing component and a second pressure-bearing component. The first pressure-bearing component is disposed on the first mating surface, and the second pressure-bearing component is disposed on the second mating surface. When the fiberglass shield mold is in the closed state, the first pressure-bearing component and the second pressure-bearing component abut against each other, so that a gap is generated between the first extrusion surface and the second extrusion surface.

[0012] Furthermore, the fiberglass shield mold also includes a guide protrusion and a guide groove. The guide protrusion is disposed on one of the first mating surface and the second mating surface, and the guide groove is disposed on the other of the first mating surface and the second mating surface. When the fiberglass shield mold is in the closed state, the guide protrusion and the guide groove are inserted and engaged to guide the movement of the upper mold.

[0013] Furthermore, wear-resistant components are provided on the sidewalls of the guide protrusions and / or guide grooves.

[0014] Furthermore, the fiberglass shield mold also includes a first heating structure and a second heating structure. The first heating structure is disposed inside the upper mold to heat the first extrusion surface, and the second heating structure is disposed inside the lower mold to heat the second extrusion surface.

[0015] Applying the technical solution of this invention, the fixed end of the driving component is located on the side of the movable plate away from the base plate, while the moving end is driven and connected to the base plate. This arrangement effectively avoids the driving component occupying the space between the base plate and the movable plate, thereby optimizing the longitudinal dimensions of the mold, saving production area, and improving the layout flexibility of the production line. The first ejector is hinged to the movable plate, and its other end passes through the lower mold and contacts the workpiece. During the demolding stage, the movement of the moving end of the driving component is directly transmitted to the movable plate, and then the force is applied to the workpiece through the first ejector, achieving precise ejection of the workpiece from the lower mold. The hinged design allows the first ejector to swing slightly when ejecting the workpiece, thereby dispersing the force acting on the first ejector, making the force on the first ejector more uniform, reducing the possibility of the first ejector getting stuck with the lower mold, and ensuring smooth demolding of the workpiece.

[0037] The technical solutions of 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. 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.

[0038] like Figures 1 to 8As shown, this embodiment of the invention provides a fiberglass shield mold. The fiberglass shield mold has a closed mold state and a closed mold state arranged opposite to each other. The fiberglass shield mold includes a base plate 10, an upper mold 21, a lower mold 22, and a demolding component. The lower mold 22 is disposed on the base plate 10, and the upper mold 21 is movably disposed above the lower mold 22 to be closer to or further away from it. The upper mold 21 has a first extrusion surface on the side facing the lower mold 22, and the lower mold 22 has a second extrusion surface on the side facing the first extrusion surface. The second extrusion surface is used to place the workpiece 01 to be processed. When the fiberglass shield mold is in the closed mold state, the first extrusion surface and the second extrusion surface cooperate to extrude the workpiece 01. The demolding component includes a driving component 61, a movable plate 62, and at least one first ejector 63. The movable plate 62 is movably disposed between the base plate 10 and the lower mold 22. One end of the first ejector 63 is hinged to the movable plate 62, and the other end of the first ejector 63 passes through the lower mold 22. The driving component 61 has a fixed end and a moving end that are arranged opposite to each other. The moving end can move relative to the fixed end. The fixed end is located on the side of the movable plate 62 away from the base plate 10. The moving end passes through the movable plate 62 and is driven to connect with the base plate 10 so as to drive the movable plate 62 to move relative to the lower mold 22, thereby driving the first ejector 63 to move to protrude from the surface of the second extrusion surface.

[0039] Applying the technical solution of this invention, the fixed end of the driving component 61 is located on the side of the movable plate 62 away from the base plate 10, while the moving end is drivenly connected to the base plate 10. This arrangement effectively avoids the driving component occupying the space between the base plate and the movable plate, thereby optimizing the longitudinal dimensions of the mold, saving the usable area of ​​the production area, and improving the layout flexibility of the production line. The first ejector 63 is hinged to the movable plate 62, and its other end passes through the lower mold 22 and contacts the workpiece 01. During the demolding stage, the movement of the moving end of the driving component 61 is directly transmitted to the movable plate 62, and then the force is applied to the workpiece 01 through the first ejector 63, realizing the precise ejection of the workpiece 01 from the lower mold 22. The hinged design allows the first ejector 63 to swing slightly when ejecting the workpiece 01, thereby dispersing the force acting on the first ejector 63, making the force on the first ejector 63 more uniform, reducing the possibility of the first ejector 63 getting stuck with the lower mold 22, and ensuring the smooth demolding of the workpiece 01.

[0040] In this embodiment, the lower mold 22 is a punch and the upper mold 21 is a die. In other embodiments, the structures of the upper mold 21 and the lower mold 22 can be selected according to the actual working conditions.

[0041] like Figures 1 to 3As shown, the first ejector 63 includes a support 631, multiple support rods 632, and an ejector block 633. The support 631 is mounted on the movable plate 62. The multiple support rods 632 are spaced apart along the extension direction of the ejector block 633. One end of each support rod 632 is hinged to the support 631 via a hinge block 634, and the other end of each support rod 632 passes through the lower mold 22. The support rods 632 are inclined from the edge of the movable plate 62 to the center of the lower mold 22. This inclined arrangement ensures a uniform distribution of the demolding force. When the movable plate 62 moves, the support rods 632 transmit the force evenly to the ejector block 633 according to their inclination angle. Furthermore, the multiple support rods 632 ensure uniform stress distribution on the ejector block 633, preventing excessive local stress concentration. The top block 633 is located on the side of the second extrusion surface facing the first extrusion surface. The ends of the multiple support rods 632 away from the movable plate 62 are respectively connected to the top block 633. When the fiberglass shield mold is in the closed state, the top block 633 is flush with the second extrusion surface; when the fiberglass shield mold is in the open state, the top block 633 protrudes from the second extrusion surface.

[0042] Meanwhile, the design of the top block 633 can increase the contact area between the first ejector 63 and the workpiece 01. The top block 633 will participate in the extrusion together with the second extrusion surface. In this way, compared with the small end area of ​​the rod structure, it is not easy to ensure that it is flush with the second extrusion surface. The top block 633 can ensure the smoothness of the surface of the workpiece 01.

[0043] Specifically, the fiberglass shield mold includes multiple first ejector pieces 63 and multiple second ejector pieces 625. The second extrusion surface has a first edge and a second edge arranged opposite to each other along a first direction. Multiple ejector blocks 633 are respectively arranged along the first edge and the second edge along a second direction, with the first direction and the second direction forming an angle. One end of the second ejector piece 625 is fixedly connected to the movable plate 62, and the other end of the second ejector piece 625 passes through the lower mold 22. The multiple second ejector pieces 625 are distributed at intervals along the first direction. This distribution method can avoid excessive force on a single ejection point, reduce damage to the workpiece 01 or mold wear caused by stress concentration during demolding, and ensure a balanced distribution of force, which is beneficial to improving the stability of the mold and the yield of the workpiece 01. Furthermore, the above-mentioned optimization of the distribution of the first ejector pieces 63 and the second ejector pieces 625 eliminates the need for full ejection on the second extrusion surface, thus ensuring the structural strength of the lower mold 22 and simplifying the mold structure, saving manufacturing costs.

[0044] In this embodiment, the first direction and the second direction are both horizontal and perpendicular to each other, and the second ejector 625 is a support rod structure that extends in the vertical direction.

[0045] like Figure 4As shown, the drive component 61 includes a cylinder body 611 and a piston rod 612. The cylinder body 611 is located on the side of the movable plate 62 away from the base plate 10 and on the outer periphery of the lower mold 22. The bottom end of the cylinder body 611 is fixedly connected to the movable plate 62, forming a fixed end. The piston rod 612 is movable relative to the cylinder body 611, and the end of the piston rod 612 away from the cylinder body 611 is fixedly connected to the base plate 10, forming a movable end. This avoids the drive component 61 occupying the longitudinal space of the mold as a whole, thereby reducing the longitudinal dimensions of the mold and making the overall mold more compact. It also makes the entire drive component 61 easier to maintain or replace from outside the mold.

[0046] Furthermore, the movable plate 62 includes a first movable plate 621 and a second movable plate 622 that fit together. The first movable plate 621 is positioned close to the lower mold 22. The cross-sectional areas of the base plate 10, the second movable plate 622, and the first movable plate 621 decrease sequentially, forming a stepped layout that creates a stable hierarchical structure with the base plate 10. When the fiberglass shield mold is in the closed state, the first movable plate 621, the second movable plate 622, and the base plate 10 fit together sequentially. The cylinder 611 is positioned on the second movable plate 622, outside the area projected onto the second movable plate 622. This avoids redundant structures found in traditional designs, resulting in a more compact overall mold.

[0047] Specifically, the first movable plate 621 is a rectangular plate, and four driving components 61 are provided, with the cylinders 611 of the four driving components 61 distributed at the four corners of the first movable plate 621.

[0048] In this application, the second ejector 625 passes through the first movable plate 621, and the bottom end of the second ejector 625 is fixedly connected to the second movable plate 622. The support 631 is disposed on the first movable plate 621.

[0049] The second movable plate 622 is provided with a reset rod 624, and the lower mold 22 is provided with a corresponding reset groove. The reset rod 624 and the reset groove are inserted and guided to guide the relative displacement between the lower mold 22 and the movable plate 62.

[0050] like Figure 3 As shown, a guide rod 11 is provided on the side of the base plate 10 facing the movable plate 62, and a guide sleeve 623 is provided on the movable plate 62. The extension direction of the guide sleeve 623 is the same as the movement direction of the movable plate 62. The guide rod 11 and the guide sleeve 623 are inserted into each other to guide the movement of the movable plate 62. The cooperation of the guide rod 11 and the guide sleeve 623 provides precise guidance for the movement of the movable plate 62, ensuring the smoothness and efficiency of the demolding action and improving the product yield.

[0051] Specifically, the first movable plate 621 is provided with a first guide hole, the second movable plate 622 is provided with a second guide hole, the guide sleeve 623 is fixed in the first guide hole and the second guide hole and passes through the first guide hole and the second guide hole, and the guide rod 11 is inserted into the guide sleeve 623.

[0052] like Figure 6 As shown, the upper mold 21 has a first mating surface on the side facing the lower mold 22, which surrounds the outer periphery of the first extrusion surface. The lower mold 22 has a second mating surface on the side facing the first mating surface, which surrounds the outer periphery of the second extrusion surface. The fiberglass shield shell mold includes a first pressure-bearing member 31 and a second pressure-bearing member 32. The first pressure-bearing member 31 is disposed on the first mating surface, and the second pressure-bearing member 32 is disposed on the second mating surface. When the fiberglass shield shell mold is in the closed state, the first pressure-bearing member 31 and the second pressure-bearing member 32 abut against each other, thereby creating a gap between the first extrusion surface and the second extrusion surface. The abutment between the first pressure-bearing member 31 and the second pressure-bearing member 32 in the closed state ensures that a predetermined gap is created between the first extrusion surface and the second extrusion surface, thus precisely controlling the size of the forming cavity. The first pressure-bearing component 31 and the second pressure-bearing component 32 not only serve the functions of positioning and gap control, but also bear most of the pressure during the molding process, reducing the direct impact on the upper mold 21 and the lower mold 22, effectively extending the service life of the mold, and reducing the frequency and cost of mold replacement in long-term production.

[0053] Specifically, a plurality of first protrusions are spaced apart on the first mating surface, and a plurality of second protrusions are spaced apart on the second mating surface. The plurality of second protrusions correspond one-to-one with the plurality of first protrusions. The plurality of first protrusions cooperate to form a first pressure-bearing member 31, and the plurality of second protrusions cooperate to form a second pressure-bearing member 32.

[0054] like Figure 7 As shown, the fiberglass shield mold also includes a guide protrusion 41 and a guide groove 42. The guide protrusion 41 is disposed on one of the first mating surface and the second mating surface, and the guide groove 42 is disposed on the other of the first mating surface and the second mating surface. When the fiberglass shield mold is in the closed state, the guide protrusion 41 and the guide groove 42 are engaged to guide the movement of the upper mold 21. The guiding engagement of the guide protrusion 41 and the guide groove 42 provides guidance for the closing of the upper mold 21 and the lower mold 22, preventing lateral displacement of the mold during the closing process, ensuring accurate alignment of the first extrusion surface and the second extrusion surface, and ensuring smooth mold closing.

[0055] In this embodiment, the guide protrusion 41 is spaced apart from the first pressure-bearing member 31, and the guide groove 42 is spaced apart from the second pressure-bearing member 32. The guide protrusion 41 is disposed on the first mating surface, and the guide groove 42 is disposed on the second mating surface.

[0056] Furthermore, wear-resistant parts 50 are provided on the sidewalls of the guide protrusion 41 and / or guide groove 42.

[0057] In this embodiment, the wear-resistant part 50 is a copper metal block with low hardness. The wear-resistant part 50 is fixed to the side of the guide protrusion 41 away from the workpiece 01 by fasteners, which reduces the hard wear when the guide protrusion 41 and the guide groove 42 are inserted and mated, thus extending the service life of the mold.

[0058] In other embodiments, the abrasion-resistant element 50 is disposed on the sidewall of the guide groove 42.

[0059] Specifically, the lower mold 22 is provided with guide posts 221, and the upper mold 21 is provided with corresponding guide grooves. The guide posts 221 and the guide grooves are inserted and guided to guide the relative displacement between the upper mold 21 and the lower mold 22. The diameter of the top of the guide post 221 gradually decreases towards the side away from the lower mold 22, so that the guide post 221 can be inserted into the corresponding guide groove more smoothly.

[0060] Furthermore, the fiberglass shield mold also includes a first heating structure and a second heating structure. The first heating structure is disposed inside the upper mold 21 to heat the first extrusion surface, and the second heating structure is disposed inside the lower mold 22 to heat the second extrusion surface.

[0061] like Figure 8 As shown, the fiberglass shield mold includes multiple spaced-apart first oil pipes 71 and multiple second oil pipes 72. The multiple first oil pipes 71 are spaced horizontally, with both ends of each first oil pipe 71 passing through the fiberglass shield mold. One end of each first oil pipe 71 is connected to the oil outlet of an oil temperature controller, and the other end is connected to the oil return of the oil temperature controller. The second oil pipes 72 are located inside the fiberglass shield mold and extend vertically. The middle of each second oil pipe 72 is connected to the first oil pipe 71, and both ends of each second oil pipe 72 are sealed. The first oil pipes 71 and second oil pipes 72 located inside the upper mold 21 cooperate to form a first heating structure, with the multiple first oil pipes 71 spaced along the contour structure of the first extrusion surface. The first oil pipes 71 and second oil pipes 72 located inside the lower mold 22 cooperate to form a second heating structure.

[0062] The upper die 21 is fixedly connected to an upper cover plate 20, which is also fixedly connected to the punch head of the press. The punch head drives the upper cover plate 20 to move up and down. The base plate 10 is fixedly connected to the punching base of the press. Multiple support columns 223 are spaced apart between the lower die 22 and the base plate 10. A die corner 224 is provided on the base plate 10, with its bottom edge wrapped around the edge of the base plate 10 and its top fixedly connected to the bottom edge of the lower die 22. The support columns 223 and the die corner 224 cooperate to fix the relative position between the lower die 22 and the base plate 10.
