Technical Field

[0001] The utility model relates to a forming die, in particular to a radiator forming die. Background Art

[0002] During the manufacturing process of the radiator, a cavity mold is usually used to shape the injected molding solution, and the radiator is formed after the molding solution cools and solidifies.

[0003] A utility model patent for a radiator molding die has been disclosed on the patent website, with the authorization announcement number CN202021769U. The device injects into the first mold cavity and the second mold cavity respectively through the first branch channel and the second branch channel, thereby achieving the purpose of molding two radiators with one mold. Although the production efficiency of the device is relatively high, due to the relatively simple structure of the device, when the molded radiator is demolded, the mold cavities and templates on both sides need to be separated respectively, and then the molded radiators need to be pushed out of the mold cavities on both sides respectively. Such an operation is relatively cumbersome, and therefore, it adds a certain burden to the staff during the actual operation.

[0004] Based on this, a heat sink forming mold that is convenient for double-cavity demoulding is proposed to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0021] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0022] Example 1: The utility model provides a radiator forming mold, such as Figures 1-6As shown, it includes a stand 1, a mold box 2, a box cover 3, a filling pipe 4, a tensioning adjustment component 5 and a demoulding component. A material taking trough 100 is opened in the middle of the top of the stand 1, and the material taking trough 100 is convenient for simultaneously pushing out the two radiators a after molding; two vertically placed mold boxes 2 are installed on the top of the stand 1, and the two mold boxes 2 are equipped with box covers 3 on opposite sides. The mold boxes 2 and the box covers 3 are used to die-cast the radiator a. A material taking channel that can accommodate two molded radiators a at the same time is reserved between the two box covers 3, which is conducive to taking out the two molded radiators a at the same time and is easy to use; the tops of the two mold boxes 2 are connected and communicated with a filling pipe 4, and a tensioning adjustment component 5 is connected between the two box covers 3. The tensioning adjustment component 5 includes a connecting frame 51, an adjusting The seat 52, the hinged arm 53, the push frame 54, the adjustment column 55 and the guide block 56, the two box covers 3 are connected to the connecting frame 51 on opposite sides, the adjusting seat 52 is movably sleeved between the two connecting frames 51, and the push frame 54 is hingedly connected to the upper and lower sides of the two connecting frames 51 through the hinged arm 53. The middle part of the push frame 54 is threadedly sleeved with an adjustment column 55, and the rear end of the adjustment column 55 is rotatably connected to the adjusting seat 52. The rear side of the push frame 54 is connected to a guide block 56 that slides with the adjustment seat 52. By rotating the adjustment column 55 forward or backward, the connecting frame 51 and the box cover 3 thereon can be pushed to be opened or closed synchronously by the push frame 54 and the hinged arm 53. A demoulding component that can simultaneously eject the radiator a on both sides is provided between the stand 1 and the mold box 2.

[0023] Further, such as Figure 1-Figure 3 As shown, the demoulding assembly includes a two-way cylinder 6, a connecting frame 7 and a push rod 8. The two-way cylinder 6 is installed on the top of the stand 1. The ends of the telescopic rods at both ends of the two-way cylinder 6 are respectively connected to the connecting frames 7. The push rod 8 is provided on the side where the connecting frames 7 are close to each other, and the push rod 8 is pulled out and plugged into the mold box 2 for pushing the formed radiator a out for unloading.

[0024] Further, such as Figure 4 and Figure 5 As shown, it also includes a positioning structure, which is composed of a positioning column 30 and a positioning hole 20. The mold box 2 is provided with a positioning hole 20, and the box cover 3 is provided with a positioning column 30 that is compatible with the positioning hole 20. By plugging the positioning column 30 into the positioning hole 20, the box cover 3 and the mold box 2 can be accurately docked.

[0025] During use, the box lids 3 on both sides are first placed in the material extraction trough 100 and aligned with the mold box 2. The alignment structure formed by the positioning column 30 and the positioning hole 20 allows the box lids 3 to be precisely docked with the mold box 2. Next, by rotating the adjustment column 55, the pusher frame 54 can be moved horizontally backward along the adjustment seat 52. This action drives the articulated arm 53 to push the connecting frame 51 thereon to expand toward each other, allowing the box lids 3 on both sides to simultaneously cling to the mold box 2. Subsequently, the molding solution is simply added to the mold box 2 through the injection tube 4. After the molding solution cools and forms, the heat sink a is formed. When the molded heat sink a needs to be demolded, the adjustment column 55 is simply rotated in the opposite direction to allow the pusher frame 54 to move horizontally forward along the adjustment seat 52. This action will pull the connecting frame 51 and the box cover 3 thereon toward each other through the driving action of the articulated arm 53, thereby facilitating the separation and removal of the box covers 3 on both sides from the mold box 2; then, the two-way cylinder 6 is started to cause the telescopic rods on it to contract toward each other, and this action will drive the connecting frame 7 and the ejector rod 8 to close together, thereby enabling the radiators a formed in the mold boxes 2 on both sides to be simultaneously pushed out for unloading, and the entire operation process is simple and convenient.

[0026] Example 2: Based on Example 1, Figure 1 、 Figure 2 、 Figure 3 and Figure 7 As shown, it also includes a feeding structure, which includes a mounting frame 9, a feeding hopper 10, an A-shaped conduit 11 and an extrusion piece. The mounting frame 9 is set between the left and right sides of the top of the platform 1, and the feeding hopper 10 is set in the middle of the top of the mounting frame 9. The bottom of the feeding hopper 10 is connected and connected to the A-shaped conduit 11, and the lower ends of the A-shaped conduits 11 are respectively connected and connected to the injection pipes 4. The feeding hopper 10 facilitates the injection of the molding solution into the mold box 2 through the A-shaped conduit 11. An extrusion piece for pressurizing the injected molding solution is provided between the mounting frame 9 and the injection pipe 4.

[0027] In addition, if Figure 1 、 Figure 2 、 Figure 3 and Figure 7 As shown, the extrusion part includes an electric cylinder 12 and a push block 13. Two groups of electric cylinders 12 are provided on the mounting frame 9. The telescopic rod of the electric cylinder 12 is movably extended into the injection tube 4, and the end of the telescopic rod of the electric cylinder 12 is connected with a push block 13. The push block 13 is in sliding contact with the inner wall of the injection tube 4. When a certain amount of molding solution is added, the telescopic rods of the two electric cylinders 12 are extended by simultaneously controlling the two electric cylinders 12 to drive the push block 13 to move downward to extrude the molding solution in the injection tube 4, thereby eliminating bubbles in the molded radiator a, which is beneficial to improving the production quality of the radiator a.
