Description

Technical Field

[0001] The utility model relates to the technical field of aluminum die-casting non-stick pan production, and specifically, to a production mold for an aluminum die-casting non-stick pan. Background Technique

[0002] Aluminum die-casting non-stick pans occupy an important position in the kitchenware market due to their light weight, durability, and excellent heat conduction performance. The manufacturing process of such non-stick pans usually involves injecting molten aluminum into a mold for die-casting, and then coating one or more non-stick coatings on the surface of the pan body. Such coatings can significantly reduce the friction between food and the pan surface, making cooking easier and more convenient, and also facilitating cleaning, with many benefits during use. However, due to the die-casting production method and the special shape of the pan body, aluminum die-casting non-stick pans still face a series of technical problems during production demolding.

[0003] The Chinese patent publication number: CN217775526U discloses a production mold for an aluminum die-casting non-stick pan, including a lower mold and an upper mold. The upper mold is combined directly above the lower mold to form a die-casting cavity. The bottom of the lower mold is provided with an assembly cavity, and an installation base is embedded in the assembly cavity. The installation base is fixed on the lower mold, and a servo motor is provided on the installation base. The output end of the servo motor is connected to a lifting rod, and an ejecting cylinder threadedly connected to the outer surface of the lifting rod is sleeved outside the lifting rod, etc. This patent drives the lifting rod to rotate through the servo motor, raises the ejecting cylinder upward, jacks up the aluminum casting, and separates the aluminum casting from the lower mold, realizing the convenient separation of the castings in the die-casting cavities of the lower mold and the upper mold.

[0004] Although the above patent can effectively solve the problem of inconvenient demolding during the die-casting production of aluminum die-casting non-stick pans, when this device is actually used, molten aluminum is injected into the die-casting cavity through a liquid injection pipe. Since the thickness of the die-casting cavity is relatively small, the aluminum liquid is not easy to flow in the cavity during pouring, and the specific fullness situation in the cavity cannot be accurately observed. After pouring, it is easy to cause incomplete filling of the aluminum liquid in the die-casting cavity, resulting in defects on the surface of the casting and low product quality. For the problems in the related technology, no effective solution has been proposed yet. Content of the Utility Model

[0005] In view of the problems in the related technology, the utility model proposes a production mold for an aluminum die-casting non-stick pan to overcome the above-mentioned technical problems existing in the existing related technology.

[0006] Therefore, the specific technical solution adopted by the utility model is as follows:

[0007] A production mold for an aluminum die-cast non-stick pan, including a lower mold. A sealing ring is fixedly connected to the surface of the lower mold. An upper mold is arranged above the sealing ring. A sealing groove is formed on the bottom surface of the upper mold. The sealing ring is matched with the sealing groove. A detection groove is formed on the top of the upper mold. A lifting cylinder is slidably installed inside the detection groove. A support plate is fixedly connected inside the lifting cylinder. Two sides of the surface of the support plate are fixedly connected with telescopic springs. The ends of the telescopic springs are fixedly connected with limit posts. Positioning holes are formed on both sides of the inner wall of the detection groove. The limit posts are matched with the positioning holes. One end of the limit post is fixedly connected with a pressing rod. The pressing rod is slidably installed in the detection groove. A grouting channel is formed on one side inside the lower mold. One end of the grouting channel is fixedly connected with a grouting mechanism.

[0008] Further, in order to inject aluminum liquid into the upper mold and the lower mold, the grouting mechanism includes a grouting pipe installed in cooperation with one end of the grouting channel. The end of the grouting pipe is fixedly connected with a feeding box. A loading groove is formed inside the feeding box. A sealing plug is slidably installed inside the loading groove. One side of the sealing plug is fixedly connected with a pushing rod. The pushing rod is slidably connected with one side of the feeding box. A feeding pipe is fixedly connected to the top of the feeding box.

[0009] Further, in order to seal the grouting channel, a movable groove is formed below the grouting channel. A sealing block is slidably installed in the movable groove. The sealing block is matched with the grouting channel. The bottom surface of the sealing block is rotatably connected with an adjusting bolt. The adjusting bolt is threadedly connected with the lower mold.

[0010] Further, in order to facilitate demolding of the lower mold, a demolding plate is slidably installed on the surface of the lower mold. The bottom surface of the demolding plate is rotatably connected with a threaded rod. The threaded rod is threadedly connected with the lower mold. The end of the threaded rod is fixedly connected with a turning disk.

[0011] Further, in order to prevent the lifting cylinder from rotating in the detection groove, limiting grooves are formed on both sides of the inner wall of the detection groove. Both ends of the support plate pass through the lifting cylinder and are slidably installed in the limiting grooves.

[0012] Further, in order to facilitate pulling the upper mold and the lower mold for demolding, pulling handles are fixedly connected to both sides of the surfaces of the upper mold and the lower mold.

[0013] Further, in order to limit the up and down movement of the lifting cylinder in the detection groove, a limiting ring is fixedly connected to the top of the lifting cylinder.

[0014] The beneficial effects of the present utility model are as follows: By pressing the lifting cylinder at the top of the upper mold, the end of the lifting cylinder slides into the die-casting cavity of the upper mold. Then, through the grouting mechanism, molten aluminum is injected into the bottom end of the die-casting cavities inside the upper mold and the lower mold. After the molten aluminum is injected from the bottom to the top in the die-casting cavity, the pressure in the die-casting cavity gradually increases as more molten aluminum is injected, causing the molten aluminum to fill all parts of the die-casting cavity. When the die-casting cavity is filled with molten aluminum, the pressure can push the lifting cylinder upward, thereby achieving a full pouring of the molten aluminum in the upper and lower molds, effectively avoiding defects in the non-stick cookware products formed by die-casting, and ensuring a high production quality of the die-cast non-stick cookware.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] According to an embodiment of the present invention, a production mold for an aluminum die-cast non-stick pan is provided.

[0025] Embodiment 1:

[0026] As Figures 1 - 5 shown, a production mold for an aluminum die-cast non-stick pan according to an embodiment of the present invention includes a lower die 1. A sealing ring 2 is fixedly connected to the surface of the lower die 1. An upper die 3 is provided above the sealing ring 2. Die-casting cavities are opened in both the upper die 3 and the lower die 1. A sealing groove 4 is opened on the bottom surface of the upper die 3. The sealing ring 2 is matched with the sealing groove 4 for sealing the die-casting cavity. A cylindrical detection groove 5 is opened at the top of the upper die 3. A lifting cylinder 6 is slidably installed inside the detection groove 5. A support plate 7 is fixedly connected inside the lifting cylinder 6. Telescopic springs 8 are fixedly connected to both sides of the surface of the support plate 7. The ends of the telescopic springs 8 are fixedly connected to limit posts 9. The limit posts 9 are slidably installed on both sides of the lifting cylinder 6. Positioning holes 10 are opened on both sides of the inner wall of the detection groove 5. The limit posts 9 are matched with the positioning holes 10. One end of the limit post 9 is fixedly connected to a pressing rod 11. The pressing rod 11 is slidably installed in the detection groove 5. After driving the limit post 9 and the limit spring to contract through the pressing rod 11, the lifting cylinder 6 slides in the detection groove 5, so that the end of the lifting cylinder 6 slides into the die-casting cavity, for detecting the pressure in the die-casting cavity by the up and down movement of the lifting cylinder 6. A grouting channel 12 is opened on one side inside the lower die 1. One end of the grouting channel 12 is fixedly connected to a grouting mechanism 13 for injecting molten aluminum liquid from the bottom of the die-casting cavity from bottom to top.

[0027] As Figures 1 - 5As shown in the figure, the grouting mechanism 13 includes a grouting pipe 1301 fitted and installed at one end of the grouting channel 12. The end of the grouting pipe 1301 is fixedly connected with a feeding box 1302 made of rectangular heat insulation material. A loading groove 1303 is formed inside the feeding box 1302. A sealing plug 1304 is slidably installed inside the loading groove 1303. One side of the sealing plug 1304 is fixedly connected with a push rod 1305. The push rod 1305 is slidably connected with one side of the feeding box 1302. By driving the sealing plug 1304 to move in the loading groove 1303 through the push rod 1305, the molten aluminum in the loading groove 1303 enters the die casting cavity through the grouting channel 12. The top of the feeding box 1302 is fixedly connected with a feeding pipe 1306 for injecting molten aluminum into the loading groove 1303. An activity groove 14 is formed below the grouting channel 12. A sealing block 15 is slidably installed inside the activity groove 14. The sealing block 15 is matched with the grouting channel 12. The bottom surface of the sealing block 15 is rotatably connected with an adjusting bolt 16. The adjusting bolt 16 is threadedly connected with the lower die 1. When the die casting cavity is not filled with molten aluminum, by turning the adjusting bolt 16, the sealing block 15 enters the grouting channel 12 to seal it. A stripping plate 17 is slidably installed on the surface of the lower die 1. The bottom surface of the stripping plate 17 is rotatably connected with a threaded rod 18. The threaded rod 18 is threadedly connected with the lower die 1. The end of the threaded rod 18 is fixedly connected with a turning disk 19. By driving the threaded rod 18 to rotate through the turning disk 19, the threaded rod 18 drives the stripping plate 17 to move upward, so that the stripping plate 17 pushes the cooled non-stick pan to be quickly stripped. Limiting grooves 20 are formed on both sides of the inner wall of the detection groove 5. Both ends of the support plate 7 pass through the lifting cylinder 6 and are slidably installed in the limiting grooves 20 to prevent the lifting cylinder 6 from rotating in the detection groove 5. Pulling handles 21 are fixedly connected to both sides of the surfaces of the upper die 3 and the lower die 1 for conveniently pulling the upper die 3 and the lower die 1 for stripping. A limiting ring 22 is fixedly connected to the top of the lifting cylinder 6 for limiting the up and down movement of the lifting cylinder 6 in the detection groove 5.

[0028] In order to facilitate the understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in the actual process will be described in detail below.

[0029] In summary, by means of the above technical solution of the present utility model, in actual application, when the two pressing rods 11 approach each other, the limiting posts 9 and the telescopic springs 8 are driven to contract, so that the lifting cylinder 6 slides downward in the detection groove 5, and then the end of the lifting cylinder 6 slides into the die casting cavity. After injecting molten aluminum liquid into the loading groove 1303 of the feeding box 1302, the sealing plug 1304 is driven to move in the loading groove 1303 by the pushing rod 1305, so that the aluminum liquid in the loading groove 1303 enters the die casting cavity of the lower mold 1 through the grouting channel 12. The aluminum liquid is injected from the bottom to the top in the die casting cavity and gradually reaches the top of the die casting cavity. After continuously injecting aluminum liquid, the pressure in the die casting cavity gradually increases, so that the aluminum liquid fills every part of the die casting cavity. When the die casting cavity is filled with aluminum liquid, the pressure can push the lifting cylinder 6 to move upward. When the limiting posts 9 on both sides of the lifting cylinder 6 slide to correspond to the positioning holes 10 in the detection groove 5 and enter the positioning holes 10 by the elastic force of the telescopic springs 8 and stop moving upward, the full injection of aluminum liquid in the upper mold 3 and the lower mold 1 is realized. After waiting for the aluminum liquid in the upper mold 3 and the lower mold 1 to cool, the upper mold 3 is demolded by pulling the handle 21, and then the threaded rod 18 is driven to rotate by turning the disc 19, so that the threaded rod 18 drives the demolding plate 17 to move upward, and then the demolding plate 17 pushes the cooled non-stick pan to be quickly demolded from the lower mold 1.

[0030] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
