Description

Technical Field

[0001] This utility model relates to the field of molding device technology, specifically to a pot body molding mold. Background Technology

[0002] In the field of modern cookware manufacturing, pot body forming molds are key equipment for achieving large-scale, standardized production of pot bodies. Through a specific cavity structure, they process raw materials such as metal sheets into pot body products with specific shapes and sizes, and are widely used in the cookware manufacturing industry. Most existing pot body forming molds adopt traditional structural designs. After the pot body forming process is completed, operators often need to manually demold the pot. This demolding method is relatively time-consuming and labor-intensive, reducing production efficiency. Furthermore, manual demolding poses certain safety hazards; operators may suffer hand injuries due to errors during frequent operations. Therefore, this utility model provides a pot body forming mold. Summary of the Invention

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1As shown, a pot-forming mold includes: a base 1, with a lower mold 2 recessed at the center of the top surface of the base 1. Several upward-extending columns 3 are arranged around the lower mold 2 on the top surface of the base 1. The bottom ends of the columns 3 are fixedly connected to the top surface of the base 1, and their top ends extend above the base 1, with a top seat 4 fixedly mounted on each top end. In this embodiment, both the base 1 and the top seat 4 are rectangular structures, and there are four columns 3 arranged near the four corners of the base 1 to maintain stability.

[0022] like Figure 2 As shown, a hydraulic cylinder 5 is installed on the top seat 4. The piston rod of the hydraulic cylinder 5 extends through the top seat 4 to below the top seat 4 and is fixedly connected to the top surface of the sliding seat 6, which is slidably mounted on the column 3. An upper mold 7 is installed at the bottom of the sliding seat 6. The hydraulic cylinder 5 can drive the sliding seat 6 and the upper mold 7 to rise and fall, so that the upper mold 7 and the lower mold 2 are closed, thereby forming the pot body. Preferably, the sliding seat 6 has a rectangular structure, and its four corners are slidably connected to the four columns 3 respectively.

[0023] Among them, such as Figure 2 As shown, the lower mold 2 includes a forming cavity 21 and a guide cavity 22. The guide cavity 22 is located above the forming cavity 21 and is shaped like an inverted frustum, wider at the top and narrower at the bottom. The upper mold 7 includes a forming upper mold 71 and a guide upper mold 72. The forming upper mold 71 is adapted to the forming cavity 21. The two work together to press the metal sheet into a pot body. The guide upper mold 72 is adapted to the guide cavity 22, realizing the guiding function of the upper and lower molds docking. The mold 7 is connected to the sliding seat 6 through a connecting seat 12. The connecting seat 12 has a cylindrical structure and its diameter is equal to the diameter of the top of the guide upper mold 72. The connecting seat 12 can prevent the bottom surface of the sliding seat 6 from contacting the top surface of the base 1 when the mold is closed.

[0024] Preferably, such as Figure 2 and Figure 4 As shown, the lower mold 2 also includes a positioning groove 23. The positioning groove 23 is located at the top of the guide cavity 22, is circular, and has a diameter larger than the top diameter of the guide cavity 22, forming a stepped placement structure at the top edge of the guide cavity 22 for placing the circular metal plate to be processed. The positioning groove 23 is adapted to the circular metal plate, ensuring that the placement position of the circular metal plate corresponds to the mold, avoiding misalignment that could lead to molding failure. Meanwhile, the top surface of the base 1 has an insertion groove 11, which extends from the edge of the base 1 to communicate with the positioning groove 23, and the depth of the insertion groove 11 is less than the depth of the positioning groove 23. The insertion groove 11 is used to place the metal plate, and then the metal plate is pushed into the positioning groove 23.

[0025] like Figure 3As shown, a connecting rod 8 is provided at the bottom of the sliding seat 6. The bottom end of the connecting rod 8 extends downward into a sliding groove opened in the base 1 and slides within the sliding groove. A horizontal crossbar 9 is provided at the bottom end of the connecting rod 8. A vertically upward push rod 10 is provided on the crossbar 9. The push rod 10 slides within an ejection groove opened inside the base 1. The ejection groove is located below the lower mold 2 and communicates with the lower mold 2. The push rod 10 can push upward from the ejection groove to eject the pot body inside the lower mold 2. Preferably, there are two connecting rods 8, symmetrically distributed on both sides of the lower mold 2, and the two ends of the crossbar 9 are respectively connected to the bottom ends of the two connecting rods 8. The push rod 10 is located in the middle of the crossbar 9 and is correspondingly positioned at the center of the lower mold 2.

[0026] When the sliding seat 6 moves to the top, the top of the push rod 10 is lower than the top surface of the base 1 to avoid affecting the placement of the metal plate.

[0027] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
