Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and particularly relates to an induction positioning distance structure for molds. Background Art

[0002] In the stamping operation of a mold, the upper mold moves downward to stamp products or workpieces in the lower mold. During long-term use, traditional molds are prone to wear and looseness problems. When subjected to impact or pressure, it is difficult to keep the position of the workpiece stable, or the fit between the upper mold and the lower mold is poor, which will result in a gap between the mold closures, making the mold closures of the upper and lower molds incomplete. This may lead to poor stamping effects of the workpiece, or the workpiece may shift or the mold may be damaged, posing a safety hazard. In such a situation, it is mostly identified manually, and then manual intervention is required to adjust the position of the workpiece during the stamping process, which is cumbersome and affects production efficiency. Summary of the Utility Model

[0003] In order to make up for the deficiencies of the prior art, the utility model proposes an induction positioning distance structure for molds.

[0004] To achieve the above object, the utility model provides the following technical solutions:

A through hole groove is provided on the side of the corner mounting block, and a guide plate rotatably connected to the corner mounting block is movably inserted into the hole groove;

[0006] The spring positioning post is fixed on the corner mounting block by a screw thread and extends into the hole groove, and is used to apply a uniform force to the guide plate to ensure that the guide plate returns to its original state after being impacted or pressured;

[0007] The induction sensor is installed on the corner mounting block and is used to monitor the position of the guide plate.

[0008] The induction sensor is used to detect the position of the guide plate, and can quickly and accurately detect the position change of the guide plate. The positioning post is used to support the guide plate, so that the guide plate can return to the initial state after being extruded. The guide plate is used for the movement path in the mold to ensure the correct position of the mold and the material during the stamping process. In addition, the induction sensor is used to connect to the PLC control system of the stamping mold system to ensure the accurate position during the operation of the mold during the stamping process, thereby ensuring the accuracy of stamping forming and the quality of the product. This structure can achieve automatic detection through the induction sensor, improving production efficiency and stability.

[0009] Preferably, the guide plate is rotatably connected to the corner mounting block through a connecting shaft, and circular holes matched with the connecting shaft are respectively provided on the guide plate and the corner mounting block.

[0010] Preferably, a waist-shaped hole is formed at one end of the corner mounting block away from the spring positioning post, and the corner mounting block is fixed to the mold by a bolt passing through the waist-shaped hole, which facilitates the installation and positioning of the corner mounting block.

[0011] Preferably, an installation hole is further formed on one side of the corner mounting block close to the waist-shaped hole, and the installation hole is used for assisting installation and positioning to improve the stability of the installation of the corner mounting block.

[0012] Preferably, after the guide plate is impacted or pressured, the spring positioning post applies a uniform force to the guide plate and ejects part of the guide plate out of the corner mounting block.

[0013] Compared with the prior art, the technical effects and advantages of the present utility model are as follows: The mold uses an induction positioning distance structure.

After the stamping is completed, the upper mold moves upward, the spring positioning post returns to its original state, applies a uniform force to the guide plate to make it return to the initial state, and the induction sensor continues to monitor the position of the guide plate to ensure the correct positions of the mold and the material.

[0014] The induction positioning distance structure of the mold can improve the precision of stamping forming and the product quality. It realizes precise positioning through the induction sensor, and is achieved through automatic detection and the PLC control system. It improves production efficiency and stability, avoids misoperation by monitoring the position change of the guide plate, ensures safety and reliability during the stamping process, reduces manual intervention, improves the degree of automation, reduces production costs.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The following is combined with Figures 1-3 To further explain this application in detail,

[0021] The embodiment of the present application discloses an inductive positioning distance structure for a mold, comprising a corner mounting block 1, a spring positioning column 4 and an inductive sensor 5. A hole slot 2 is provided on the side of the corner mounting block 1 and penetrates the corner mounting block 1. A guide plate 3 rotatably connected to the corner mounting block 1 is movably inserted into the hole slot 2.

[0022] The spring positioning column 4 is threadedly fixed on the corner mounting block 1 through the screw rod 10 and extends into the hole groove 2 and is used to apply a uniform force to the guide plate 3 to ensure that the guide plate 3 returns to its original state after being impacted or pressed;

[0023] The inductive sensor 5 is mounted on the corner mounting block 1 and is used to monitor the position of the guide plate 3 .

[0024] The spring positioning column 4 applies a uniform force to the guide plate 3 after the guide plate 3 is impacted or pressed, and partially pushes the guide plate 3 out of the corner mounting block 1 .

[0025] During the stamping process, the upper die will cooperate with the lower die to stamp. In order to monitor the stamping status and ensure the accuracy of stamping and the quality of the product, the sensing positioning distance structure is installed on the lower die seat or the lower die. When the upper die moves downward along the motion path, the guide plate 3 is squeezed toward the inside of the hole slot 2, so that the outer surface of the guide plate 3 is flush with the outer surface of the corner sensor (such as Figure 1 As shown), at this time, the spring positioning column 4 is compressed by the impact and pressure of the mold and the guide plate 3 (the spring positioning column is a component in the mold, which is used to keep the workpiece in the correct position during the stamping or forming process. This positioning column usually contains a spring that can be compressed when it is impacted or pressurized). The inductive sensor 5 can sense and monitor that the guide plate 3 is squeezed to the inner side of the hole groove 2, which can ensure the accurate positioning of the upper and lower molds during the stamping process;

[0026] like Figure 2As shown, after the upper die and the lower die are stamped, the upper die moves upward and away from the guide plate 3. At this time, when the spring positioning post 4 returns to its original state, it exerts a uniform force on the guide plate 3, causing the guide plate 3 to return to its initial state (the so-called initial state is the state where the guide plate 3 is not extruded by the upper die. At this time, part of the guide plate 3 protrudes from the corner mounting plate, and the induction sensor 5 cannot detect the position of the guide plate 3);

[0027] The induction sensor 5 is used to detect the position of the guide plate 3, and can quickly and accurately detect the position change of the guide plate 3. The positioning post is used to support the guide plate 3, so that the guide plate 3 can return to its initial state after being extruded. The guide plate 3 is used for the movement path in the mold to ensure the correct position of the mold and the material during the stamping process. In addition, the induction sensor 5 is used to connect to the PLC control system of the stamping die system to ensure the accurate position during the stamping process, thereby ensuring the precision of stamping forming and the quality of the product. This structure can achieve automatic detection through the induction sensor 5, improving production efficiency and stability.

[0028] The model of the spring positioning post 4 is PJL6-3,

[0029] The guide plate 3 is rotatably connected to the corner mounting block 1 through a connecting shaft 9. Round holes 6 that cooperate with the connecting shaft 9 are respectively formed on the guide plate 3 and the corner mounting block 1.

[0030] A waist-shaped hole 7 is formed at one end of the corner mounting block 1 away from the spring positioning post 4. The corner mounting block 1 is fixed to the mold by a bolt passing through the waist-shaped hole 7, which is convenient for the installation and positioning of the corner mounting block 1.

[0031] An installation hole 8 is also formed on one side of the corner mounting block 1 close to the waist-shaped hole 7. The installation hole 8 is used to assist in installation and positioning, improving the installation stability of the corner mounting block 1.

[0032] For the induction positioning distance structure of this mold, when the mold is stamped, the upper die moves downward to cooperate with the lower die, and the guide plate 3 is extruded into the hole groove 2, and its outer surface is flush with the corner sensor. The spring positioning post 4 is compressed when it is impacted or pressured to keep the workpiece in the correct position. The induction sensor 5 monitors the position change of the guide plate 3. When the guide plate 3 is extruded into the hole groove 2, the sensor senses it and transmits a signal. After stamping is completed, the upper die moves upward, the spring positioning post 4 returns to its original state, and exerts a uniform force on the guide plate 3 to make it return to its initial state. The induction sensor 5 continues to monitor the position of the guide plate 3 to ensure the correct position of the mold and the material.

[0033] The induction positioning distance structure of this mold can improve the precision and product quality of stamping forming. Precise positioning is achieved through the induction sensor 5, and it is realized through automatic detection and the PLC control system, which improves production efficiency and stability. By monitoring the position change of the guide plate 3, misoperation is avoided, ensuring safety and reliability during the stamping process, reducing manual intervention, increasing the degree of automation, lowering production costs. The spring positioning column 4 can ensure that the guide plate 3 returns to its original state after being impacted or pressured, guaranteeing the long-term use and stability of the mold.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
