Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance manufacturing technology, specifically to a pressure cooker lid forming device. Background Technology

[0002] As a core component of the sealing and pressure-bearing system, the molding quality of the pressure cooker lid directly affects the safety, sealing performance, and service life of the pressure cooker. With the development of kitchen appliances towards lightweight and high safety, traditional pressure cooker lid manufacturing processes can no longer meet modern production needs. Therefore, developing a pressure cooker lid molding equipment is of great practical significance in order to meet the molding and processing requirements of pressure cooker lids.

[0003] Referring to the CN207628949U specification, a mold forming device for an electric pressure cooker lid includes a base plate. A groove is formed on the top of the base plate, and an n-shaped lower mold seat is slidably mounted within the groove. A lower mold is mounted on the top of the lower mold seat, and a rack is mounted on the inner side of the lower mold seat. Two columns are mounted on the top of the base plate, and a first fixing plate is mounted between the tops of the two columns. A second motor and a guide sleeve are mounted on the bottom of the first fixing plate. The output shaft of the second motor is connected to a lead screw, and the lead screw is externally connected to a threaded sleeve. The device has a threaded nut sleeve with a rectangular boss fixedly fitted on its exterior. Two sets of guide sleeves are provided, each with a guide post slidably fitted inside. An upper mold base is installed between the ends of the two guide posts furthest from the guide sleeves. This device facilitates obtaining accurate data to improve the quality of parts during later molding, makes it easier to remove parts, and increases production efficiency. However, while this device can be well applied, it is generally not convenient to limit the downward pressure of the upper mold, making it prone to damage to the lower mold due to high downward pressure. Further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a forming device for a pressure cooker lid, in order to solve the problem that although the device proposed in the background art can be applied well, it is usually not convenient to abut and limit the downward pressure of the upper mold, which makes the upper mold prone to damage to the lower mold due to the high downward pressure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a forming device for a pressure cooker lid, comprising a base plate, a base fixedly installed on one side of the top of the base plate, a cabinet fixedly installed on the top of the base plate on one side of the base plate, a pedestal at the top of the base plate, and columns at the corners of the top of the pedestal. A threaded post is fixed to the end of each column away from the pedestal. An upper mold base is movably connected to the outer wall of several threaded posts. Locking nuts are threaded onto the outer wall of the threaded posts above the upper mold base. The bottom end of the locking nuts contacts the top of the upper mold base. An upper mold is installed at the bottom of the upper mold base. A plurality of columns below the upper mold are connected to the upper mold base. A lower mold base is fixed to the wall, and a lower mold is installed on the top of the lower mold base. Lower strip seats are provided on both sides of the lower mold. Support rods are installed on both sides of the bottom of the lower strip seats. The end of the support rod away from the lower strip seat is connected to the outer wall of the base. Upper strip seats are provided on both sides of the upper mold. A limiting cylinder is provided at the corner of the top of the upper mold base. A limiting rod is movably connected inside the limiting cylinder. The bottom end of the limiting rod passes through the upper mold base and is connected to the top of the upper strip seat. The top end of the limiting rod extends to the outside of the limiting cylinder and is provided with a hexagonal end cap. A spring is wound on the outer wall of the limiting rod above the limiting cylinder. A control cabinet is provided on the surface of the cabinet.

[0006] Preferably, a component holder is fixedly installed on the outer wall of the threaded column above the upper mold base. A lifting cylinder is installed at the top of the component holder, and the bottom end of the lifting cylinder is connected to the top of the upper mold base. The lifting cylinder is used to drive the upper mold base to move up and down.

[0007] Preferably, the inner side of the upper mold base is provided with an injection tube head, the bottom end of which is connected to the top end of the upper mold, so that the material can be injected into the interior of the upper mold through the setting of the injection tube head.

[0008] Preferably, a feeding machine body is provided on the outer wall of one side of the injection tube head, and one end of the feeding machine body is connected to the outer wall of the injection tube head. The feeding machine body is provided to facilitate the placement of the spiral roller.

[0009] Preferably, a spiral roller is rotatably installed inside the feeding machine body, and a material inlet is provided on one side of the top of the feeding machine body, so that materials can be injected into the interior of the feeding machine body.

[0010] Preferably, a motor is installed on the outer wall of the feeding machine body on the side away from the injection pipe head. One end of the motor extends into the interior of the feeding machine body and is connected to one end of the spiral roller. The motor is configured to drive the spiral roller to rotate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the forming equipment for the pressure cooker lid not only reduces the phenomenon of pressure damage to the lower mold caused by the high pressure of the upper mold, but also achieves the purpose of easy and convenient forming of the pressure cooker lid, and improves the convenience of feeding the forming equipment.

[0012] (1) Due to the good elasticity of the spring, when the upper mold base moves downward and drives the upper mold to move downward synchronously, the upper strip seat first contacts the top of the lower strip seat. As the upper mold moves downward continuously, the limiting rod moves upward inside the limiting cylinder and makes the spring extend until the bottom of the upper mold contacts the top of the lower mold, and the top of the upper strip seat contacts the bottom of the upper mold base, so as to achieve the purpose of abutting and limiting the upper mold, thereby reducing the phenomenon of the upper mold being damaged by the high downward pressure of the upper mold.

[0013] (2) By starting the lifting cylinder, the upper mold base is driven to slide down the outer wall of the threaded column and the column, so that the upper mold base drives the upper mold to move down smoothly. When the bottom end of the upper mold contacts the top end of the lower mold, the pressure pot lid can be formed in the mold cavity inside the lower mold and the upper mold, thereby achieving the purpose of easy and convenient forming of the pressure pot lid.

[0014] (3) The material required for the pressure cooker lid is injected into the inside of the feeding machine through the injection port. When the motor is started, the motor drives the spiral roller to rotate inside the feeding machine. At this time, the spiral roller will spiral the material to the left and deliver it to the injection tube head so that the material falls into the mold cavity inside the upper and lower molds through the bottom of the injection tube head, thereby improving the convenience of feeding the molding equipment.

[0023] The inner side of the upper mold base 8 is provided with an injection tube head 25, and the bottom end of the injection tube head 25 is connected to the top end of the upper mold 11.

[0024] In use, the material is injected into the interior of the upper mold 11 through the setting of the injection tube head 25;

[0025] A feeding machine body 19 is provided on the outer wall of one side of the injection pipe head 25, and one end of the feeding machine body 19 is connected to the outer wall of the injection pipe head 25.

[0026] In use, the spiral roller 26 is positioned by setting the feeding body 19;

[0027] A spiral roller 26 is rotatably installed inside the feeding machine body 19, and a feeding port 21 is provided on one side of the top of the feeding machine body 19;

[0028] In use, the material is injected into the inside of the feeding machine body 19 through the setting of the injection port 21;

[0029] A motor 20 is installed on the outer wall of the feeding machine body 19 on the side away from the injection pipe head 25. One end of the motor 20 extends into the interior of the feeding machine body 19 and is connected to one end of the spiral roller 26.

[0030] In use, the motor 20 is configured to drive the spiral roller 26 to rotate;

[0031] Locking nuts 24 are threaded onto the outer wall of the threaded pillars 7 above the upper mold base 8. The bottom end of the locking nuts 24 contacts the top end of the upper mold base 8. An upper mold 11 is installed at the bottom end of the upper mold base 8. A lower mold base 15 is fixed to the outer wall of several pillars 6 below the upper mold 11. A lower mold 18 is installed at the top end of the lower mold base 15. Lower strip seats 17 are provided on both sides of the lower mold 18. Support rods 16 are installed on both sides of the bottom end of the lower strip seats 17. The end of the support rod 16 away from the lower strip seat 17 is connected to... The outer wall of the base 5 is connected, and upper strip seats 14 are provided on both sides of the upper mold 11. A limiting cylinder 12 is provided at the corner of the top of the upper mold seat 8. A limiting rod 13 is movably connected inside the limiting cylinder 12. The bottom end of the limiting rod 13 passes through the upper mold seat 8 and is connected to the top of the upper strip seat 14. The top end of the limiting rod 13 extends to the outside of the limiting cylinder 12 and is provided with a hexagonal end cap 23. A spring 22 is wound on the outer wall of the limiting rod 13 above the limiting cylinder 12. A control cabinet 3 is provided on the surface of the cabinet 2.

[0032] In this embodiment, the lifting cylinder 10 is first activated, causing the upper mold base 8 to slide downwards along the outer wall of the threaded column 7 and the column 6. This allows the upper mold base 8 to smoothly lower the upper mold 11. When the bottom of the upper mold 11 contacts the top of the lower mold 18, the pressure cooker lid is formed within the mold cavity of the lower mold 18 and the upper mold 11. Then, the material required for the pressure cooker lid is injected into the loading body 19 through the injection port 21. When the motor 20 is activated, it drives the spiral roller 26 to rotate inside the loading body 19. The spiral roller 26 then spirally conveys the material to the left into the injection pipe head 25, allowing the material to fall through the bottom of the injection pipe head 25 into the mold cavity inside the upper mold 11 and the lower mold 18, thus facilitating material loading. Finally, thanks to the good elasticity of the spring 22, when the upper mold base 8 moves downward and drives the upper mold 11 to move downward synchronously, the upper strip seat 14 first contacts the top of the lower strip seat 17. As the upper mold 11 continues to move downward, the limiting rod 13 moves upward inside the limiting cylinder 12, and the spring 22 is stretched until the bottom of the upper mold 11 contacts the top of the lower mold 18, and the top of the upper strip seat 14 contacts the bottom of the upper mold base 8, so as to abut and limit the downward movement of the upper mold 11. After the pressure cooker lid is formed, the upper mold 11 is moved upward so that the pressure cooker lid is in the mold cavity inside the lower mold 18. After the current pressure cooker lid has cooled down, it is taken out, and the next pressure cooker lid can be formed, thus completing the use of the forming equipment.
