Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panels, and in particular to an injection mold for an aluminum frame of a photovoltaic panel and an aluminum frame for a photovoltaic panel. Background Technology

[0002] The outline of a photovoltaic panel is usually covered by a photovoltaic aluminum frame to ensure the overall strength of the photovoltaic panel and prevent deformation. Conventional photovoltaic aluminum frames are injection molded from molten aluminum. During the molding process, because the photovoltaic aluminum frame is relatively thin and the molten aluminum has a long flow path in the cavity, the molten aluminum flows in the cavity for a long time at a low flow rate. This causes the molten aluminum to solidify, which prevents the molten aluminum from filling the cavity. Ultimately, this results in a high defect rate of the photovoltaic aluminum frame after the mold is opened. In summary, how to ensure that molten aluminum completely fills the cavity during the injection molding process of photovoltaic aluminum frames has become an urgent problem for researchers in this field. Summary of the Invention

[0003] The technical problem to be solved by this utility model is: how to achieve complete filling of the cavity with molten aluminum during the injection molding process of photovoltaic aluminum frame; To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model relates to an injection mold for an aluminum frame of a photovoltaic panel, comprising: an upper mold core with an upper cavity at its bottom; a lower mold core with a lower cavity protruding from its top, wherein flow portions are provided at the front, back, left, and right sides of the inner side of the lower cavity; an upper mold plate, disposed above the upper mold core, with a transition plate between the upper mold core and the upper mold core; a cross-shaped flow divider, wherein the flow divider is disposed within the transition plate, with an inlet at the top center of the flow divider and four outlets on the bottom surface of each end of the flow divider, the outlets being connected to the corresponding flow portions via connecting pipes; a sprue sleeve, disposed at the center of the upper mold plate, with its bottom connected to the inlet; and a heating tube, disposed in the flow divider and arranged around the contour of the flow divider.

[0004] Furthermore, a heating sleeve is provided on the outer side of the sprue sleeve.

[0005] Furthermore, a protrusion is provided on the front side of the lower cavity, and a first gap is formed between the protrusion and the lower cavity.

[0006] Furthermore, the convex strip is provided with a plurality of spaced second gaps along its length direction.

[0007] This utility model also discloses a photovoltaic panel aluminum frame, which is injection molded by a photovoltaic panel aluminum frame injection mold.

[0008] Furthermore, it includes: a vertical wall that encloses and forms a frame, wherein the top of the vertical wall forms a horizontal pressing edge inward.

[0009] Furthermore, a partition is provided on the rear side of the vertical wall, forming a space for storing wire bundles between the partition and the vertical wall.

[0010] Furthermore, multiple sheet-like reinforcing ribs are formed between the vertical wall and the partition.

[0011] The beneficial effects of this utility model are as follows: This utility model is a photovoltaic panel aluminum frame injection mold and a photovoltaic panel aluminum frame. Since the flow section has four outlets and the distribution section has four outlets, the medium (molten aluminum) can enter the cavity in four directions: front, back, left, and right. This results in a shorter flow distance for each medium in the cavity, thus ensuring that the medium in the cavity does not solidify due to a long flow distance. In addition, a heating tube is provided in the distribution section, and the operation of the heating tube prevents the medium from solidifying when it is in the distribution section.

Detailed Implementation

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0015] See Figure 6 This embodiment is a photovoltaic panel aluminum frame. The photovoltaic panel aluminum frame includes a vertical wall 01 that encloses and forms a frame body. The vertical wall 01 is generally rectangular. The top of the vertical wall 01 forms a horizontal pressing edge 02 inward. The horizontal pressing edge 02 presses against the surface of the photovoltaic panel, placing the photovoltaic panel inside the photovoltaic panel aluminum frame. The photovoltaic panel is then fixed by covering it with a cover plate. A partition 03 is provided on the rear side of the vertical wall 01, and a space 04 is formed between the partition 03 and the vertical wall 01. The wire harness connected to the photovoltaic panel is stored in this space to avoid the wire harness being exposed to the outside, which would lead to failure of the wire harness after long-term use. Multiple reinforcing ribs 05 are provided between the vertical wall 01 and the partition 03. The purpose of the reinforcing ribs 05 is to increase the strength of the partition 03 and prevent the partition 03 from deforming.

[0016] See Figure 1-5 To form the photovoltaic panel aluminum frame in the above embodiments, this solution also discloses a photovoltaic panel aluminum frame injection mold, including: an upper mold core 1 with an upper cavity 11 recessed at its bottom; a lower mold core 2 with a lower cavity 21 protruding at its top, and flow portions 3 provided at the front, back, left, and right sides of the inner side of the lower cavity 21; an upper mold plate 4, which is disposed above the upper mold core 1, and a transition plate 5 is provided between the upper mold core 1 and the upper mold core 4; a cross-shaped flow divider 6, which is disposed within the transition plate 5, with an inlet at the top center of the flow divider 6 and four outlets 62 on the bottom surface of each end of the flow divider 6, the outlets 62 being connected to the corresponding flow portions 3 via connecting pipes 7; a sprue sleeve 8, which is disposed at the center of the upper mold plate 4, and its bottom is connected to the inlet; and a heating tube 9, which is disposed in the flow divider 6 and arranged around the contour of the flow divider 6. In this embodiment, after the upper mold core 1 and the lower mold core 2 are molded together, a cavity for forming the aluminum frame of the photovoltaic panel is formed. At this time, the upper cavity 11 is located outside the lower cavity 21. The horizontal gap between the upper cavity 11 and the lower cavity 21 is used to form the vertical wall 01, and the vertical gap between the upper cavity 11 and the lower cavity 21 is used to form the pressure plate 02. The medium enters from the sprue sleeve 8, flows through the inlet of the diversion section 6, and flows out from the bottom surface through four outlets 62. Then it enters the corresponding flow section 3 through the connecting pipe 7, and finally enters the cavity. Since there are four flow sections 3 and four outlets 62 in the diversion section 6, the medium (aluminum liquid) can enter the cavity in four directions: front, back, left, and right. In this way, the flow distance of each medium in the cavity is short, which can ensure that the medium in the cavity does not solidify due to the long flow distance. In addition, a heating bundle tube 9 is provided in the diversion section 6. The operation of the heating bundle tube 9 prevents the medium from solidifying when it is in the diversion section 6.

[0017] In some possible embodiments, a heating sleeve 81 is provided on the outside of the gate sleeve 8; The heating jacket 81 has the same function as the heating bundle tube 9, which is to prevent the medium located inside the sprue jacket 8 from solidifying.

[0018] In some possible embodiments, a protrusion 22 is provided on the front side of the lower cavity, and a first gap 23 is formed between the protrusion 22 and the lower cavity 21; the protrusion 22 is provided with a plurality of spaced second gaps 24 along its length direction; In this embodiment, the medium fills the first gap 23 to form a partition 03, and the medium fills the second gap 24 to form a reinforcing rib 05.

[0019] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
