Description

Technical Field

[0001] This utility model relates to the field of pot production and processing technology, and in particular to a calibration mold and calibration equipment. Background Technology

[0002] In the stainless steel kitchenware industry, handles with base plates are often used in kitchenware design and assembly. To ensure product assembly accuracy and achieve mass production, the handle base plates must be calibrated. Currently, rigid calibrating molds are commonly used, with both the upper and lower mold components made of rigid materials. While this type of mold has advantages in mass production and ensuring calibration accuracy, it also has significant drawbacks: the handle base plates often get scratched or even cracked during calibration, leading to increased production costs and decreased production efficiency. Using flexible calibrating molds can solve the problem of handle scratches and cracks, but the calibration accuracy is slightly lower or even fails to meet product precision requirements. Utility Model Content

[0003] The main purpose of this utility model is to propose a calibration mold and calibration equipment, which aims to ensure the calibration accuracy of stainless steel kitchenware handle base plates while avoiding defects such as scratches and cracks during the calibration process, thereby improving production efficiency and reducing costs.

Under the action of the hydraulic press, the upper template can reciprocate along the Z-axis direction, driving the upper mold to adjust the handle seat piece of the positioning groove or separate from the handle seat piece.

[0007] The outer guide post connects the upper template and the lower template, and the outer guide post is used to guide the upper template in the Z-axis direction;

[0008] The inner guide post connects the lower mold to the lower template and guides the lower mold in the Z-axis direction.

[0009] In one embodiment, the elastic element includes at least one of an elastic pad and a spring.

[0010] In one embodiment, two outer guide pillars are provided, and the two outer guide pillars are respectively located at opposite ends of the lower template along the X-axis direction.

[0011] In one embodiment, the lower mold assembly further includes bolts, which are fixed to the lower template.

[0012] The elastic element is sleeved on the bolt, and the elastic element is used to generate elastic contraction in the Z-axis direction when the upper template reciprocates along the Z-axis direction.

[0013] In one embodiment, the lower template is provided with a mounting groove, one end of the elastic member is embedded in the mounting groove, and the other end of the elastic member extends out of the mounting groove and abuts against the lower template.

[0014] In one embodiment, the lower mold assembly further includes a fixing plate, which is mounted on the lower mold plate, and the inner guide post connects the lower mold to the fixing plate.

[0015] In one embodiment, the fixed plate and the lower template form a calibration space at corresponding positions, the calibration space through which the handle body passes and can reciprocate along the Y-axis to adjust the calibration position of the handle body.

[0016] This utility model also proposes a calibration device, including the calibration mold as described above.

[0027] In the stainless steel kitchenware industry, handles with base plates are often used in kitchenware design and assembly. To ensure product assembly accuracy and achieve mass production, the handle base plates must be calibrated. Currently, rigid calibrating molds are commonly used, with both the upper and lower mold components made of rigid materials. While this type of mold has advantages in mass production and ensuring calibration accuracy, it also has significant drawbacks: the handle base plates often get scratched or even cracked during calibration, leading to increased production costs and decreased production efficiency. Using flexible calibrating molds can solve the problem of handle scratches and cracks, but the calibration accuracy is slightly lower or even fails to meet product precision requirements.

[0028] To solve the above problems, this utility model proposes a calibration mold 100.

[0029] Please see Figure 1 In one embodiment of this utility model, the calibration mold 100 includes:

[0030] The lower mold assembly 1 includes a lower template 11, a lower mold 12 and an elastic element 13. The lower template 11 and the lower mold 12 are arranged opposite to each other. The elastic element 13 is located between the lower template 11 and the lower mold 12. The lower mold 12 is provided with a positioning groove 101 on the side away from the lower template 11 for positioning the seat piece 210 of the handle 200.

[0031] The upper mold assembly 2 includes an upper template 21 and an upper mold 22. The upper mold 22 is disposed on the upper template 21 and faces the positioning groove 101. The upper mold 22 and the lower mold 12 are made of rigid material. The upper template 21 is used to be movably connected to the hydraulic press. Under the action of the hydraulic press, the upper template 21 can reciprocate along the Z-axis direction, driving the upper mold 22 to adjust the handle 200 seat piece 210 of the positioning groove 101 or to separate from the handle 200 seat piece 210.

[0032] The outer guide post 3 connects the upper template 21 and the lower template 11. The outer guide post 3 is used to guide the upper template 21 in the Z-axis direction.

[0033] The inner guide post 4 connects the lower mold 12 to the lower template 11 and guides the lower mold 12 from the Z-axis direction.

[0034] In this embodiment, the lower mold assembly 1 consists of a lower template 11, a lower mold 12, and an elastic element 13, wherein the lower template 11 and the lower mold 12 are arranged opposite to each other, and the elastic element 13 is disposed between the two. This structure allows the elastic element 13 to provide buffering force during the calibration process, thereby effectively mitigating the impact caused by rigid contact and preventing the handle 200 seat piece 210 from being scratched or cracked when under pressure; the lower mold 12 has a positioning groove 101 on the side opposite to the lower template 11, which is used to accurately position the seat piece 210, ensuring positional stability during the calibration process and improving processing consistency. The upper mold assembly 2 includes an upper template 21 and an upper mold 22. The upper mold 22 is mounted on the upper template 21 and is set towards the positioning groove 101. Its material is rigid to ensure the shape control accuracy during the shaping process. The upper template 21 is movably connected to the hydraulic press through a movable slider. Under the drive of the hydraulic press, it can reciprocate along the Z-axis, driving the upper mold 22 to perform shaping operations on the seat piece 210 in the positioning groove 101 or to complete the demolding action, thereby realizing automated continuous production. The alignment mold 100 can also be equipped with an outer guide post 3 and an inner guide post 4. The outer guide post 3 connects the upper template 21 and the lower template 11 together and is used to guide the movement trajectory of the upper template 21 in the Z-axis direction, thereby improving the alignment accuracy between the upper mold 22 and the lower mold 12 and preventing misalignment from causing alignment errors. At the same time, the inner guide post 4 connects the lower mold 12 and the lower template 11 and is also used to guide the movement of the lower mold 12 in the Z-axis direction, enhancing the movement stability of the lower mold 12 during the compression and springback process of the elastic element 13, and further ensuring alignment accuracy and repeatability.

[0035] In summary, this embodiment, by employing rigid upper mold 22 and lower mold 12, ensures consistency between calibration accuracy and mass production. The elastic element 13 between the lower mold 12 and lower template 11 enables flexible pressing of the handle 200 base plate 210, reducing the risk of scratches and cracks. The positioning groove 101 of the lower mold 12 enhances the positioning reliability of the base plate 210 and improves processing stability. The dual guiding mechanism of the outer guide post 3 and inner guide post 4 ensures the alignment accuracy and operational stability of the upper mold 22 and lower mold 12 during movement. While retaining the advantages of traditional rigid molds, the overall solution, by introducing the elastic element 13, solves the product damage problem caused by excessive rigidity in existing technologies, without sacrificing calibration accuracy. This improves production efficiency and reduces costs while ensuring product quality.

[0036] Please see Figure 1 In one embodiment, the elastic element 13 includes at least one of an elastic pad and a spring.

[0037] Please see Figure 1 In one embodiment, there are two outer guide posts 3, which are respectively located at opposite ends of the lower template 11 along the X-axis direction.

[0038] In this embodiment, two outer guide pillars 3 are provided, and the two outer guide pillars 3 are respectively located at opposite ends of the lower template 11 along the X-axis direction. This layout allows the upper template 21 to obtain more uniform and stable guiding support through the symmetrically arranged outer guide pillars 3 on both sides when it moves along the Z-axis direction under the drive of the hydraulic press, effectively preventing the upper template 21 from swaying or tilting during operation.

[0039] This embodiment, through the rational configuration of the number of outer guide pillars 3 and their distribution at both ends of the lower template 11, not only improves the structural stability of the alignment mold 100, but also enhances the alignment accuracy and motion synchronization between the upper mold 22 and the lower mold 12, thereby further ensuring the consistency of the alignment process and the accuracy of repeated positioning. Simultaneously, this symmetrical guiding structure helps extend the mold's service life, reduces wear and errors caused by unstable guidance, and improves production efficiency and product yield.

[0040] Please see Figure 1 In one embodiment, the lower mold assembly 1 further includes a bolt 14, which is fixed to the lower template 11; an elastic element 13 is sleeved on the bolt 14, and the elastic element 13 is used to generate elastic contraction in the Z-axis direction when the upper template 21 reciprocates along the Z-axis direction.

[0041] In this embodiment, the lower mold assembly 1 further includes a bolt 14, which is fixedly installed on the lower template 11 and serves as a guide and support structure for the elastic element 13. The elastic element 13 is sleeved on the outside of the bolt 14 and arranged along the Z-axis. When the upper template 21 drives the upper mold 22 to move downward for shaping, it can generate elastic compression deformation in the Z-axis direction and recover its original shape by its own elastic force after the shaping is completed, thereby realizing the buffering and resetting function of the lower mold 12.

[0042] In this embodiment, the cooperation between bolt 14 and elastic element 13 not only achieves stable transmission of the elastic buffer function, but also limits the lateral displacement of elastic element 13 during compression, preventing it from shifting or becoming unstable, thus improving the reliability and repeatability of the calibration mold 100. At the same time, the bolt 14 provides a convenient installation method for the elastic element 13, facilitating future maintenance and replacement.

[0043] Please see Figure 1In one embodiment, the lower template 11 is provided with an installation groove 102, one end of the elastic member 13 is embedded in the installation groove 102, and the other end of the elastic member 13 extends out of the installation groove 102 and abuts against the lower mold 12.

[0044] In this embodiment, the lower template 11 is provided with a mounting groove 102. One end of the elastic member 13 is embedded in the mounting groove 102, and the other end extends out of the mounting groove 102 and abuts against the bottom surface of the lower mold 12. This structure enables the elastic member 13 to be stably positioned during assembly, preventing it from shifting or falling off, thereby ensuring that it reliably transmits the buffering force during the calibration process.

[0045] In this embodiment, by embedding the elastic element 13 part into the mounting groove 102 of the lower template 11, not only can the installation stability of the elastic element 13 be enhanced, but the overall compactness and assembly accuracy of the calibration mold 100 can also be improved. At the same time, its protruding part is in direct contact with the lower mold 12, which can generate elastic compression along the Z-axis direction when the upper mold 22 applies pressure, providing controllable flexible support for the lower mold 12, thereby reducing rigid impact and effectively reducing the risk of scratches or cracks in the seat piece 210 during the calibration process, further improving the quality of the handle product and the service life of the calibration mold 100.

[0046] Please see Figure 1 In one embodiment, the lower mold assembly 1 further includes a fixing plate 15, which is installed on the lower template 11, and the inner guide post 4 connects the lower mold 12 to the fixing plate 15.

[0047] In this embodiment, the lower mold assembly 1 further includes a fixing plate 15, which is mounted on the lower mold plate 11. The inner guide post 4 connects the lower mold 12 to the fixing plate 15. This structure uses the fixing plate 15 as the mounting reference for the inner guide post 4, enabling the inner guide post 4 to stably guide the movement of the lower mold 12 in the Z-axis direction, thereby improving the linearity and stability of the lower mold 12's vertical movement during the shaping process.

[0048] In this embodiment, by setting the fixing plate 15, not only can the connection rigidity between the inner guide post 4 and the lower template 11 be enhanced, but the movement consistency of the lower mold 12 during the compression and reset process of the elastic element 13 can also be improved, avoiding offset or jamming caused by unstable guidance, and further ensuring the alignment accuracy and the reliability of mold operation. At the same time, the setting of the fixing plate 15 also provides a more stable support foundation for the assembly of the inner guide post 4, improving the overall structural strength and service life of the mold.

[0049] Please see Figure 1 In one embodiment, a calibration space 103 is formed at the corresponding positions of the fixing plate 15 and the lower template 11. The calibration space 103 allows the handle 200 handle body 220 to pass through and reciprocate along the Y-axis to adjust the calibration position of the handle 200 handle body 220.

[0050] In this embodiment, a calibration space 103 is formed between the fixed plate 15 and the lower template 11 at corresponding positions. This space allows the handle 220 of the handle 200 to pass through and allows it to reciprocate along the Y-axis, thereby enabling precise calibration of the handle 200 base plate 210 at different positions or angles.

[0051] This embodiment enhances the applicability and flexibility of the calibration mold 100 by introducing a calibration space 103 adjustable along the Y-axis within the calibration mold 100. During the calibration process, the operator can adjust the position of the handle 220 within the calibration space 103 as needed, ensuring a more precise relative position between the seat 210 and the upper and lower molds 22, thereby improving calibration accuracy and consistency. Simultaneously, this design facilitates adaptation to various models or specifications of handle 200 products, expanding the versatility of the calibration mold 100 and increasing its utilization rate and production efficiency.

The specific structure of the calibration mold 100 is as described in the above embodiments. Since this calibration equipment adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0053] Please see Figure 1 In one embodiment, the calibration equipment can be a hydraulic press or a punch press. By installing the calibration mold 100 on such equipment, large-scale, high-precision automated calibration processing of stainless steel handle 200 base pieces 210 can be achieved, further improving production efficiency and product consistency.
