Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mold technology, specifically relating to a guide post and guide sleeve structure that is easy to install and remove. Background Technology
[0002] As a core guiding component of the mold, the guide rod's primary function is to ensure precise guidance and positioning when the moving and fixed molds close, preventing molding defects caused by misalignment. By installing a guide sleeve on the guide rod, the up-and-down movement of the guide sleeve can buffer the force during mold opening and closing, ensuring stable mold operation under high-speed opening and closing and load changes.
[0003] To improve the stability of the guide sleeve when it moves on the guide rod, a limiting cap is usually installed at one end of the guide rod to prevent the guide sleeve from detaching from the guide rod when it moves along the guide rod. However, the existing limiting cap is usually fixed to the guide rod with bolts, and the installation and removal of the limiting cap also require the use of a special wrench, which is cumbersome and increases the difficulty of replacing the guide sleeve or maintaining the guide post and guide sleeve structure, making it inconvenient for people to use. Utility Model Content
[0004] The purpose of this utility model is to provide a guide post and guide sleeve structure that is easy to install and remove, in order to solve the technical problem of cumbersome operation in the above-mentioned background technology, in order to address the shortcomings of the existing technology.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A guide post and sleeve structure that is easy to install and remove includes: a guide rod, a limiting component, and a power supply assembly. The guide rod is made of a magnetic material, and a mounting cavity is formed at the top of the guide rod, with a coil disposed within the mounting cavity. The limiting component includes: an end cap and a magnetic element. The diameter of the first end of the magnetic element is smaller than the diameter of its second end. The second end of the magnetic element is connected to the end cap. The magnetic element is disposed within the mounting cavity, with the first end of the magnetic element located inside the coil and the second end of the magnetic element located outside the coil and abutting against the side wall of the mounting cavity. The end cap movably closes the mounting cavity. The power supply assembly is disposed inside the guide rod, and the power supply terminal of the power supply assembly is electrically connected to the coil.
[0007] Furthermore, the easy-to-install and detach guide post and guide sleeve structure also includes: an inner guide sleeve and an elastic element, the bottom of the guide rod is embedded in the base, the inner surface of the inner guide sleeve is sleeved on the outer surface of the guide rod, the inner guide sleeve is movably abutting against the end cap, and the elastic element is sleeved on the guide rod and is respectively connected to the inner guide sleeve and the base.
[0008] Furthermore, the easy-to-install and detach guide post and guide sleeve structure also includes: an outer guide sleeve, the inner surface of which is fitted onto the outer surface of the inner guide sleeve.
[0009] Furthermore, an annular mounting groove is provided at the bottom of the mounting cavity, and the coil is located in the mounting groove.
[0010] Furthermore, a first insulating layer is provided at the bottom of the mounting groove.
[0011] Furthermore, the power supply component includes: a power supply module, a toggle switch, and a connecting wire. The power supply module is disposed in a receiving cavity opened inside the base. The bottom of the mounting slot has a through hole communicating with the receiving cavity. The toggle switch is disposed at the end of the base and is electrically connected to the power supply module. One end of the connecting wire is electrically connected to the power supply module, and the other end of the connecting wire passes through the through hole and is connected to the coil.
[0012] Furthermore, multiple guide cavities are spaced apart on the side wall surrounding the mounting cavity, and multiple guide blocks are provided on the outer surface of the second end of the magnetic component, with each guide block slidably disposed within a guide cavity.
[0013] Furthermore, a plurality of insertion holes are spaced apart on the end face surrounding the guide rod, and insertion rods are provided on the end of the end cap near the guide rod, the position and number of which correspond to the insertion holes. When each guide block is disposed in a guide cavity, each insertion rod is inserted into a insertion hole.
[0014] Furthermore, a second insulating layer is provided on the outer surface of the end cap.
[0015] Furthermore, the end cap is made of a non-magnetic material.
[0016] Furthermore, the outer surface of the guide rod is provided with a magnetic shielding layer.
[0017] The beneficial effects of this invention are as follows: During the assembly of the guide post and guide sleeve structure, the limiting component is placed into the mounting cavity. Power is supplied to the coil via the power supply component, causing the coil to generate a magnetic field opposite to that of the magnetic component, thus weakening the magnetic field of the magnetic component. This allows the limiting component to be easily placed into the mounting cavity. Afterward, the power supply module is de-energized, the magnetic field of the magnetic component is restored, and the second end of the magnetic component generates an attractive force that holds the side wall of the mounting cavity, fixing the limiting component to the guide post. When it is necessary to remove the limiting component, the power supply module, in conjunction with the coil, weakens the magnetic field of the magnetic component, allowing the limiting component to be easily removed from the mounting cavity. This design simplifies the installation and removal of the limiting component, greatly reducing the difficulty of assembling and maintaining the guide post and guide sleeve structure.

Detailed Implementation
[0025] Example 1
[0026] like Figures 1 to 5 As shown, a guide post and sleeve structure that is easy to install and remove includes: a guide rod 10, a limiting member 30, and a power supply assembly. The guide rod 10 is made of a magnetic material. The top end of the guide rod 10 has an installation cavity 11, and a coil 20 is disposed in the installation cavity 11. The limiting member 30 includes: an end cap 31 and a magnetic element 32. The diameter of the first end of the magnetic element 32 is smaller than the diameter of its second end. The second end of the magnetic element 32 is connected to the end cap 31. The magnetic element 32 is disposed in the installation cavity 11, and the first end of the magnetic element 32 is located inside the coil 20. The second end of the magnetic element 32 is located outside the coil 20 and abuts against the side wall of the installation cavity 11. The first end and the second end of the magnetic element 32 are two cylinders connected vertically. The end cap 31 is movably closed to seal the installation cavity 11. The end cap 31 is made of a non-magnetic material. The power supply assembly is disposed inside the guide rod 10, and the power supply end of the power supply assembly is electrically connected to the coil 20.
[0027] In use, first, power the coil 20 using the power supply component. After holding the end cap 31 of the limiting member 30, place the magnetic component 32 of the limiting member 30 into the mounting cavity 11. The coil 20, after being energized, can generate a magnetic field opposite to that of the magnetic component 32, thereby weakening the magnetic field of the magnetic component 32. The diameter of the first end of the magnetic component 32 is smaller than the diameter of its second end, which can prevent the end face of the first end of the magnetic component 32 from contacting the coil 20 and damaging the coil 20 when the magnetic component 32 enters the mounting cavity 11, thus allowing the magnetic component 32 to easily enter the mounting cavity 11. 1. When the power supply component is de-energized, the magnetic field of the magnetic component 32 is restored, and the outer surface of the second end of the magnetic component 32 can attract the side wall of the mounting cavity 11. The end cap 31 abuts against the top of the guide rod 10, and the end cap 31 closes the mounting cavity 11, thereby fixing the limiting component 30 to the guide rod 10. When it is necessary to remove the limiting component 30, the magnetic field of the magnetic component 32 is weakened by the power supply module 41 and the coil 20. After holding the end cap 31 of the limiting component 30, the limiting component 30 is lifted outward, and the limiting component 30 can be easily removed from the mounting cavity 11. Through the above settings, the installation and removal of the limiting component 30 is simplified, greatly reducing the difficulty of assembling and maintaining the guide post and guide sleeve structure. Among them, the guide rod 10 is made of iron-nickel alloy, the magnetic component 32 is a magnet, and the end cap 31 is made of austenitic stainless steel. The iron-nickel alloy has excellent magnetic permeability, and the attraction force generated by the magnet can attract the side wall of the mounting cavity 11, thereby fixing the limiting component 30 to the guide rod 10. The end cap 31, made of austenitic stainless steel, has weak magnetic conductivity, which can prevent the end cap 31 from sticking to the top of the guide rod 10, thereby reducing the difficulty of removing the limiting component 30.
[0028] Preferably, the guide post and guide sleeve structure, which is easy to install and remove, further includes: an inner guide sleeve 50 and an elastic element 60. The bottom of the guide rod 10 is embedded in the base 12. The inner surface of the inner guide sleeve 50 is fitted onto the outer surface of the guide rod 10. The inner guide sleeve 50 is movably abutted against the end cap 31. The elastic element 60 is fitted onto the guide rod 10 and is connected to both the inner guide sleeve 50 and the base 12. In use, the inner guide sleeve 50 supports the moving platen of the mold. When the mold opens and closes, the moving platen drives the inner guide sleeve 50 to move up and down. The elastic element 60 can buffer the pressure of the inner guide sleeve 50 during its up and down movement, thereby ensuring the stability of the mold opening and closing process. It should be noted that the elastic element 60 is a spring.
[0029] Preferably, the guide post and guide sleeve structure that is easy to install and remove further includes: an outer guide sleeve 70, the inner surface of which is fitted onto the outer surface of the inner guide sleeve 50. The outer guide sleeve 70 provides additional guiding support and reduces direct contact between the inner guide sleeve 50 and the external environment, thereby improving the stability of the guide post and guide sleeve structure during use.
[0030] Preferably, the bottom of the mounting cavity 11 has an annular mounting groove 111, and the coil 20 is located in the mounting groove 111. The mounting groove 111 can effectively fix the position of the coil 20 and prevent the coil 20 from shaking in the mounting cavity 11.
[0031] Preferably, the power supply assembly includes: a power supply module 41, a toggle switch, and a connecting wire 43. The power supply module 41 is disposed within a receiving cavity 121 inside the base 12. A through hole communicating with the receiving cavity 121 is provided at the bottom of the mounting groove 111. The toggle switch is disposed at the end of the base 12 and electrically connected to the power supply module 41. One end of the connecting wire 43 is electrically connected to the power supply module 41, and the other end of the connecting wire 43 passes through the through hole and is connected to the coil 20. In use, the toggle switch can control the power supply of the power supply module 41 to the coil 20. When it is necessary to insert or remove the limiting member 30, pushing the toggle switch to the open position allows the power supply module 41 to supply power to the coil 20 in conjunction with the connecting wire 43, thereby realizing the insertion or removal of the limiting member 30. Pushing the toggle switch to the closed position cuts off the power supply of the power supply module 41 to the coil 20, thereby allowing the limiting member 30 to be fixed on the guide rod 10. The power supply module 41 can be a secondary battery with a microcontroller control circuit, and the power supply terminal of the battery is the power supply terminal of the power supply component.
[0032] Preferably, a first insulating layer is provided at the bottom of the mounting groove 111. The first insulating layer can effectively isolate the current of the coil 20, prevent the current from being conducted downward to the bottom of the guide rod 10 and the base, and improve the safety during use.
[0033] Preferably, multiple guide cavities 13 are spaced apart on the sidewall surrounding the mounting cavity 11, and multiple guide blocks 33 are provided on the outer surface of the second end of the magnetic component 32. Each guide block 33 is slidably disposed within a guide cavity 13. Through the cooperation between the guide block 33 and the guide cavity 13, the assembly difficulty of the limiting component 30 can be reduced, ensuring that the magnetic component 32 enters the mounting cavity 11 along a predetermined path, and preventing the coil 20 from being pressed down when the first end of the magnetic component 32 enters, thereby ensuring the reliability of the guide post and guide sleeve structure during use.
[0034] Preferably, a plurality of insertion holes 14 are spaced apart on the end face surrounding the guide rod 10, and insertion rods 311, the position and number of which correspond to the insertion holes 14, are provided on the end of the end cap 31 near the guide rod 10. When each guide block 33 is disposed in a guide cavity 13, each insertion rod 311 is inserted into an insertion hole 14. The cooperation between the insertion holes 14 and the insertion rods 311 can enhance the connection strength between the end cap 31 and the top end of the guide rod 10, and improve the stability of the connection between the end cap 31 and the top end of the guide rod 10.
[0035] Preferably, the outer surface of the end cap 31 may be provided with a second insulating layer. The second insulating layer at the end of the end cap 31 near the guide rod 10 can prevent the current of the coil 20 from being conducted to the end cap 31 along the magnetic component 32, thereby improving the safety when picking up and placing the limiting component 30.
[0036] Preferably, the outer surface of the guide rod 10 is provided with a magnetic shielding layer. The magnetic shielding layer can be made of austenitic stainless steel. This magnetic shielding layer can effectively isolate the magnetism between the guide rod 10 and the outside world, reduce the magnetic interference of the guide post and guide sleeve structure on the mold during use, and thus improve the stability and reliability of the guide post and guide sleeve structure.
