Description

Technical Field

[0001] This utility model relates to a sheet metal mold. Background Technology

[0002] Currently, sheet metal production lines are crucial equipment for producing extruded sheets. For example, Chinese patent CN110228178B discloses a PEEK cold-extruded sheet production line. In this line, material is extruded into a sheet metal mold via an extruder, where it is shaped to form sheet metal products. These products then sequentially extend to a tempering and shaping device, a traction machine, and a cutting machine. The tempering and shaping device, traction machine, and cutting machine are collectively referred to as auxiliary equipment, and their height needs to be adjusted according to the height of the lower surface of the sheet metal products.

[0003] Sheet metal molds typically include an upper mold plate, a lower mold plate, and a frame plate located between the upper and lower mold plates. The upper mold plate, lower mold plate, and frame plate together form a mold cavity. An extruder forces material from the feed channel of the sheet metal mold into the mold cavity, where it is then shaped to form a sheet metal product. However, in existing sheet metal molds, the feed channel is usually located on the frame plate. For example, the feed channel in a cold push-extrusion sheet metal mold disclosed in Chinese Patent No. CN219522985U is located on the frame plate. This structure necessitates readjusting the height of the auxiliary machine when producing sheet metal products of different thicknesses, thus increasing the workload of machine adjustment. Specifically, the feed channel on the frame plate is connected to the extruder's outlet, so its height is fixed. When producing thicker sheet metal products, a thicker frame plate is required, resulting in a lower surface and a higher upper surface of the sheet metal product extruded from the mold cavity compared to the original. Similarly, when producing thinner sheet metal products, a thinner frame plate is required. This results in the lower surface of the sheet metal product extruded from the mold cavity being higher than before, while the upper surface is lower. Therefore, the height of the lower surface of the sheet metal product changes when producing products of different thicknesses. Since the height of the auxiliary machine needs to be adjusted according to the height of the lower surface of the sheet metal product, the height of the auxiliary machine must be readjusted every time a different thickness of sheet metal product is produced. This increases the workload and time spent on machine setup, making it very inconvenient to use. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a plate mold that can reduce the workload of machine adjustment, save adjustment time and improve the convenience of use when producing plate products of different thicknesses without readjusting the height of the auxiliary machine.

[0012] The feed connector is connected to the lower plate.

[0013] The middle section feed hole includes a first hole in the lower plate and a second hole in the lower liner. The front section feed hole, the first hole, the second hole and the rear section feed hole are connected in sequence to form the feed channel.

[0014] Furthermore, the lower surface of the upper liner and the upper surface of the lower liner are respectively provided with a Teflon layer.

[0015] Furthermore, the upper end of the upper plate is connected to an upper reinforcing rib, and the lower end of the lower plate is connected to a lower reinforcing rib.

[0016] Furthermore, a specific structure of the frame plate is provided, the frame plate including a middle plate, a left side plate and a right side plate;

[0017] The middle plate, the left side plate, and the right side plate are all disposed between the upper liner plate and the lower liner plate, and the rear feed hole is disposed in the middle plate;

[0018] The upper end face of the middle plate, the upper end face of the left plate, and the upper end face of the right plate are respectively in contact with and attached to the upper liner plate;

[0019] The lower end face of the middle plate, the lower end face of the left plate, and the lower end face of the right plate are respectively in contact with and attached to the lower liner plate;

[0020] The left end of the middle plate is provided with a left connecting protrusion that is connected to the front end of the left side plate, and the right end of the middle plate is provided with a right connecting protrusion that is connected to the front end of the right side plate. The mold cavity is located between the left side plate, the middle plate and the right side plate, and the discharge port of the mold cavity is located between the left side plate and the right side plate.

[0021] Furthermore, the left connecting protrusion is provided with a left dividing groove, and the right connecting protrusion is provided with a right dividing groove.

[0022] Furthermore, the upper plate has an upper heating part and an upper cooling part located behind the upper heating part.

[0027] The above technical solution involves connecting the feed connector to an extruder. The extruder forces material into the front feed hole, which then flows through the middle and rear feed holes before entering the die cavity and uniformly filling it. The material is then formed in the die cavity to obtain sheet metal products, which are extruded from the die cavity's outlet. When producing sheet metal products of different thicknesses, different thickness frame plates need to be replaced. Because the feed connector is connected to the extruder, its height is fixed, and consequently, the height of the lower die plate remains constant. Therefore, when producing sheet metal products of different thicknesses, the height of the lower surface of the extruded sheet metal product from the die cavity remains constant. The height of the auxiliary machine is adjusted based on the height of the lower surface of the sheet metal product. Thus, when producing sheet metal products of different thicknesses, only the frame plates of different thicknesses need to be replaced without readjusting the height of the auxiliary machine, reducing the workload of machine setup, saving setup time, improving ease of use, and facilitating the production of sheet metal products of different thicknesses.

[0035] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0036] like Figures 1-6 As shown, a sheet metal mold includes an upper template 1, a lower template 2, a frame plate 3, and a feeding connector 4;

[0037] The upper template 1, the side plate 3, and the lower template 2 are stacked sequentially from top to bottom, and the upper template 1, the side plate 3, and the lower template 2 surround each other to form a mold cavity 5;

[0038] The feed connector 4 is connected to the lower template 2 and is used to connect to the extruder 100. The feed connector 4 is provided with a front feed hole 6 for receiving the material extruded from the extruder 100, the lower template 2 is provided with a middle feed hole 7, and the side plate 3 is provided with a rear feed hole 8. The front feed hole 6, the middle feed hole 7 and the rear feed hole 8 are connected in sequence to form a feeding channel.

[0039] The rear feed hole 8 is connected to the front end of the mold cavity 5, and the rear end of the mold cavity 5 is provided with a discharge port for extruding the sheet material formed in the mold cavity 5. Specifically, the feed connector 4 is used to connect to the extruder 100, which is used to squeeze the material into the front feed hole 6. The material then flows through the middle feed hole 7 and the rear feed hole 8 and flows into the mold cavity 5, evenly filling the mold cavity 5. The material is then formed in the mold cavity 5 to obtain a sheet material, which is then extruded from the discharge port of the mold cavity 5. When producing sheet metal products of different thicknesses, it is necessary to replace the frame plates 3 with those of different thicknesses. Since the feed connector 4 is connected to the extruder 100, its height is fixed, and consequently, the height of the lower die 2 remains constant. Therefore, when producing sheet metal products of different thicknesses, the height of the lower surface of the sheet metal product extruded from the die cavity 5 remains constant. The height of the auxiliary machine is adjusted according to the height of the lower surface of the sheet metal product. Therefore, when producing sheet metal products of different thicknesses, only the frame plates 3 of different thicknesses need to be replaced without readjusting the height of the auxiliary machine. This reduces the workload of machine adjustment, saves adjustment time, improves ease of use, and facilitates the production of sheet metal products of different thicknesses. The auxiliary machine includes a tempering and shaping device 200, a traction machine 300, and a cutting machine, etc.

[0040] like Figures 1-5 As shown, the upper template 1 may include an upper plate 9 and an upper liner 10 that is attached to the lower end of the upper plate 9;

[0041] The lower template 2 includes a lower plate 11 and a lower liner 12 that is attached to the upper end of the lower plate 11;

[0042] The upper plate 9, the upper liner plate 10, the side plate 3, the lower liner plate 12 and the lower plate 11 are stacked sequentially from top to bottom, and the upper liner plate 10, the side plate 3 and the lower liner plate 12 surround to form the mold cavity 5;

[0043] The feed connector 4 is connected to the lower plate 11;

[0044] The middle section feed hole 7 includes a first hole in the lower plate 11 and a second hole in the lower liner 12. The front section feed hole 6, the first hole, the second hole and the rear section feed hole 8 are connected in sequence to form the feed channel.

[0045] like Figures 1-5 As shown, the lower surface of the upper liner 10 and the upper surface of the lower liner 12 are respectively provided with Teflon layers, which can prevent materials from sticking to the upper liner 10 and the lower liner 12.

[0046] like Figures 1-5As shown, the upper end of the upper plate 9 is connected to an upper reinforcing rib 13, and the lower end of the lower plate 11 is connected to a lower reinforcing rib 14. The upper reinforcing rib 13 can make the upper plate 9 thinner, and the lower reinforcing rib 14 can make the lower plate 11 thinner, thereby saving material costs while ensuring strength.

[0047] like Figures 1-5 As shown, the frame plate 3 may include a middle plate 15, a left side plate 16, and a right side plate 17;

[0048] The middle plate 15, the left side plate 16 and the right side plate 17 are all disposed between the upper liner plate 10 and the lower liner plate 12, and the rear feed hole 8 is disposed in the middle plate 15;

[0049] The upper end face of the middle plate 15, the upper end face of the left side plate 16, and the upper end face of the right side plate 17 respectively abut against and adhere to the upper liner plate 10;

[0050] The lower end face of the middle plate 15, the lower end face of the left side plate 16, and the lower end face of the right side plate 17 are respectively in contact with and attached to the lower liner plate 12.

[0051] The left end of the middle plate 15 is provided with a left connecting protrusion 18 that is connected to the front end of the left side plate 16, and the right end of the middle plate 15 is provided with a right connecting protrusion 19 that is connected to the front end of the right side plate 17. The mold cavity 5 is located between the left side plate 16, the middle plate 15 and the right side plate 17, and the discharge port of the mold cavity 5 is located between the left side plate 16 and the right side plate 17. Specifically, the middle plate 15 has a coat hanger structure.

[0052] like Figure 4 As shown, the left connecting protrusion 18 is provided with a left dividing groove 20, and the right connecting protrusion 19 is provided with a right dividing groove 21; specifically, the left dividing groove can reduce heat transfer between the middle plate 15 and the left side plate 16, and the right dividing groove 21 can reduce heat transfer between the middle plate 15 and the right side plate 17.

[0053] like Figures 1-5 As shown, the upper plate 9 has an upper heating part 22 and an upper cooling part 23 located behind the upper heating part 22. The upper heating part 22 is located above the front end of the mold cavity 5. The upper heating part 22 is provided with an upper mounting hole 24 for mounting a heating rod, and the upper cooling part 23 is provided with an upper cooling hole 25 for cooling water to flow through.

[0054] The lower plate 11 has a lower heating section 26 and a lower cooling section 27 located behind the lower heating section 26. The lower heating section 26 is located below the front end of the mold cavity 5. The lower heating section 26 has a lower mounting hole 28 for mounting a heating rod, and the lower cooling section 27 has a lower cooling hole 29 for allowing cooling water to flow through. Specifically, when the material is just squeezed into the front end of the mold cavity 5 from the rear feed hole 8, the heating rod in the upper mounting hole 24 transfers heat to the material in the front end of the mold cavity 5 through the upper heating section 22 and the upper liner 10. The heating rod in the lower mounting hole 28 transfers heat to the material in the front end of the mold cavity 5 through the lower heating section 26 and the lower liner 12, thereby maintaining a higher temperature for the material in the front end of the mold cavity 5 and thus maintaining good fluidity. Then, as the material flows backward in the mold cavity 5, the cooling water in the upper cooling hole 25 will cool and shape the material in the mold cavity 5 through the heat transfer of the upper cooling part 23 and the upper liner plate 10. The cooling water in the lower cooling hole 29 will cool and shape the material in the mold cavity 5 through the heat transfer of the lower cooling part 27 and the lower liner plate 12, thereby cooling and shaping the material in the mold cavity 5 to obtain a sheet product. Then, the sheet product is extruded from the discharge port of the mold cavity 5.

[0055] like Figure 1 , 2 As shown, the upper plate 9 is provided with an upper partition groove 30 located between the upper heating part 22 and the upper cooling part 23, and the lower plate 11 is provided with a lower partition groove 31 located between the lower heating part 26 and the lower cooling part 27. Specifically, multiple upper partition grooves 30 and lower partition grooves 31 are arranged sequentially along the left and right directions. The upper partition groove 30 can reduce the heat transfer between the upper heating part 22 and the upper cooling part 23, and the lower partition groove 31 can reduce the heat transfer between the lower heating part 26 and the lower cooling part 27.

[0056] like Figures 1-5 As shown, a brake component is connected to the upper template 1. The brake component is located above the discharge port of the mold cavity 5 and is used to abut against the upper surface of the sheet material extruded from the mold cavity 5, thereby applying extrusion resistance to the sheet material. Specifically, by applying extrusion resistance to the sheet material, the material in the mold cavity 5 can have a certain pressure, thereby making the material fill the mold cavity 5 more evenly.

[0057] like Figures 1-5 As shown, the braking component includes a brake seat 32 connected to the upper template 1 and a brake strip 33 connected to the brake seat 32 and used to abut against the upper surface of the sheet material extruded from the mold cavity 5; in this embodiment, the brake seat 32 is connected to the upper plate body 9.

[0058] In summary, the feed connector 4 is used to connect to the extruder 100. The extruder 100 is used to squeeze the material into the front feed hole 6. The material then flows through the middle feed hole 7 and the rear feed hole 8 and flows into the mold cavity 5, filling the mold cavity 5 evenly. The material is then formed in the mold cavity 5 to obtain a sheet product. The sheet product is then extruded from the outlet of the mold cavity 5. When producing sheet products of different thicknesses, it is necessary to replace the frame plate 3 with one of different thicknesses. Since the feed connector 4 is connected to the extruder 100, the height of the feed connector 4 is fixed, and consequently, the height of the lower die 2 is also fixed. Therefore, when producing sheet products of different thicknesses, the height of the lower surface of the sheet product extruded from the die cavity 5 remains constant. The height of the auxiliary machine is adjusted according to the height of the lower surface of the sheet product. Thus, when producing sheet products of different thicknesses, only the frame plate 3 with one of different thicknesses needs to be replaced, without needing to readjust the height of the auxiliary machine. This reduces the workload of machine adjustment, saves adjustment time, improves ease of use, and makes it convenient for users to produce sheet products of different thicknesses.

[0059] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
