Description

Technical Field

[0001] This utility model relates to the technical field of mold positioning detection tools, and in particular to a portable mold ejector plate positioning safety protection device. Background Technology

[0002] During the mold manufacturing process, the positioning of the ejector plate directly affects the mold's operational safety and service life. Current ejector plate positioning detection devices for molds suffer from several technical defects: First, they lack an effective structure for accurate ejector plate positioning detection, making it impossible to promptly determine whether the ejector plate has retracted into place. If the ejector plate fails to retract properly before mold closing, it can easily cause collision damage to mold components, increasing mold repair costs and production downtime. Second, existing detection devices have complex installation procedures and lack convenient and quick fixing structures. Installation requires multiple sets of tools for cumbersome assembly, and precise alignment of components is difficult and time-consuming, severely impacting the overall mold installation and debugging efficiency. Third, the fixing stability of the detection components is insufficient. Vibrations generated during mold operation can easily cause displacement of the detection components, reducing detection accuracy and making it impossible to reliably determine the actual position of the ejector plate. Fifth, the device has poor adaptability. Customized detection components are required to address the differences in ejector plate detection positions for different mold specifications, increasing equipment operating costs and requiring frequent component replacements. This cumbersome operation makes it difficult to meet the diverse detection needs of molds. Therefore, improvements are needed to address these issues. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figures 1 to 4 This utility model discloses a portable mold ejector plate positioning safety protection device, including a strong magnetic base 1. The strong magnetic base 1 facilitates the supply of power to a metal plate 3 to generate an electromagnetic adsorption effect and fix a guide rod 4. The strong magnetic base 1 is connected to an external control system. The model of the strong magnetic base 1 is CZ-6A. A knob 2 is installed at the center of the front end of the strong magnetic base 1, which facilitates the control of the power supply to and from the strong magnetic base 1, thereby determining the adsorption effect of the metal plate 3 on the bottom surface of the strong magnetic base 1 and the fixing effect on the guide rod 4. A metal plate 3 is installed on the bottom surface of the strong magnetic base 1. The metal plate 3 facilitates the adsorption of the strong magnetic base 1 onto the surface of a metal material when the strong magnetic base 1 is powered on. A snap-fit ​​hole is opened in the center of the top surface of the strong magnetic base 1. A guide rod 4 is installed in the middle of the top surface of the base 1. The guide rod 4 provides a limiting structure for the mounting plate 7, allowing the mounting plate 7 to slide and be positioned freely on the guide rod 4. The mounting plate 7 is sleeved on the outer side of the guide rod 4. The mounting plate 7 facilitates the installation and fixing of the positioning sensor 12 with the external fixing components. A mounting hole 11 is opened on the lower side of one side of the mounting plate 7. The mounting hole 11 facilitates the installation of the positioning sensor 12 with the external fixing components. The mounting plate 7 is equipped with a positioning sensor 12 that matches the mounting hole 11. The positioning sensor 12 facilitates the detection of whether the ejector plate is in position. The positioning sensor 12 is connected to the external control system. The positioning sensor 12 is a high-temperature resistant IMH30.

[0015] In this utility model, a positioning block 5 with a matching snap-fit ​​hole is installed on the bottom surface of the guide rod 4. The positioning block 5 facilitates the quick positioning of the guide rod 4 to snap-fit ​​the snap-fit ​​hole and engage with the strong magnetic base 1. Two snap-fit ​​grooves 6 are opened on the lower outer side of the guide rod 4. The snap-fit ​​grooves 6 facilitate the limiting of the subsequent mounting plate 7. The guide rod 4 engages with the positioning block 5 and engages with the strong magnetic base 1. A countersunk hole 8 is longitudinally opened on the front end of the other side of the mounting plate 7. A threaded groove is opened on the inner wall of the countersunk hole 8 and the countersunk hole 8 penetrates the mounting plate 7. The countersunk hole 8 facilitates the engagement of the inner threaded groove with the bolt 13 for threaded connection. The mounting plate 7 has a sliding hole 9 at its front top end, which facilitates quick pairing of the mounting plate 7 with the guide rod 4. A vertical tension groove 10 is provided on the other side of the sliding hole 9, which ensures that the mounting plate 7 is tightly connected to the guide rod 4 during the subsequent fixing process. The tension groove 10 is connected to the sliding hole 9 and extends vertically through the mounting plate 7. The countersunk hole 8 is threaded with a bolt 13 in conjunction with the threaded groove on the inner wall, which serves to connect the mounting plate 7 and the guide rod 4.

[0016] Working principle: When using this utility model, it is necessary to connect to the strong magnetic base 1 and the positioning sensor 12 through an external power supply line, and the signal end of the positioning sensor 12 is connected to the external control system through an external signal transmission line. Then, the positioning sensor 12 is fixed to the mounting plate 7 through an external fixing component. The guide rod 4 is connected to the strong magnetic base 1 through the positioning block 5 and the snap-fit ​​hole opened in the strong magnetic base 1. Then, the metal plate 3 on the bottom surface of the strong magnetic base 1 is placed in the predetermined design position, and then the device is powered on. When the equipment is powered on, turning knob 2 energizes the strong magnetic base 1, which attracts the guide rod 4. The metal plate 3 will also be tightly attracted to the pre-designed metal base surface through the principle of electromagnetic induction. Then, the sliding hole 9 opened in the mounting plate 7 passes through the guide rod 4, so that the mounting plate 7 and the guide rod 4 are slidably connected. Rotating the mounting plate 7 (while observing the external control system) allows the position sensor 12 to detect the position of the ejector plate. After the position sensor 12 detects the position of the ejector plate, the mounting plate 7 is tightly fixed to the outside of the guide rod 4 by the extrusion tension groove 10 through the external tool, bolt 13 and the threaded groove opened in the inner wall of the countersunk hole 8. The installation is then completed. When in use, the position sensor 12 will detect whether the ejector plate is in position during each run of the mold.
