Its main function is that during the die-casting process, when the molten metal fills the cavity, under a certain pressure and temperature, the casting can be cooled and solidified in the mold. In this process, the connecting slider mechanism is designed to move at the appropriate time to achieve delayed ejection of the casting.

[0003] The delayed mold opening mechanism of the slider of the die-casting mold on the market, most of the die-casting molds involved in the mold opening sequence will use a cylinder structure to assist in driving the connecting slider, and control the opening and closing time of the connecting slider driven by the cylinder through the die-casting machine control system to achieve the purpose of delay. Adding a cylinder to the mold will make it inconvenient for the operator to operate the machine, and the debugging time will also increase. After the cylinder is installed, the overall mold size increases, and the size of the corresponding die-casting machine also needs to be increased accordingly, resulting in an increase in the cost of the corresponding die-casting parts, and the trial machine has limitations and inconvenience in operation.

DETAILED DESCRIPTION

[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] See also Figure 1-3 In this embodiment, a delayed mold opening mechanism of a die-casting mold slider includes an upper mold 2 and a lower mold 1. Delay positioning columns 7 are fixedly connected to both sides of the bottom of the upper mold 2, and support columns 3 are fixedly connected to both sides of the bottom of the lower mold 1. Delay mold opening structures are provided on the lower part of the upper mold 2 and on both sides of the lower mold 1.

[0021] The delayed mold opening structure includes a positioning seat 12, one side of the positioning seat 12 is fixedly connected to the lower mold 1, and both sides of the lower mold 1 are fixedly connected with electric telescopic rods 16, the output end of the electric telescopic rod 16 is directed upward, and the output end of the electric telescopic rod 16 is fixedly connected with a drag seat 17, and the top of the drag seat 17 is in contact with a movable column 15, and the movable column 15 is fixedly connected to a positioning block 13 on one side facing the middle of the lower mold 1, and the positioning block 13 is fixedly connected to an external electromagnet 14 on one side facing the middle of the lower mold 1.

[0022] In this embodiment, the top of the upper mold 2 is connected to an injection port 4 , a processing groove 6 is opened in the middle of the lower mold 1 , and a pressing block 5 is arranged in the middle of the bottom of the upper mold 2 .

[0023] In this embodiment, a delay positioning groove 8 is provided inside the delay positioning column 7 . The delay positioning groove 8 is located on one side of the delay positioning column 7 close to the pressing block 5 and is fixedly connected to an internal electromagnet 9 .

[0024] The upper mold 2 is connected to the limiting groove 11 inside the lower mold 1 through the delayed positioning column 7.

[0025] It should be noted that an electromagnet is a device that uses electric current to generate a magnetic field. It consists of a coil wound around an iron core and the iron core itself. When current passes through the coil, a magnetic field is generated. This magnetic field magnetizes the iron core, making it magnetic.

[0026] It is understandable that compared with traditional magnets, the advantage of electromagnets lies in the controllability and adjustability of their magnetism. Magnets have permanent magnetism, but the magnitude of their magnetic force is fixed and cannot be changed by external control. Electromagnets can accurately control the magnitude of their magnetic force by controlling the magnitude of the current, and are suitable for applications that require precise control of the magnitude of the magnetic force.

[0027] In practical applications, electromagnets are widely used in various devices, such as motors, generators, transformers, electromagnetic locks, maglev trains, etc. The use of electromagnets makes the functions of these devices more flexible and efficient.

[0028] In this embodiment, a movable groove 10 is provided on one side of the lower mold 1 close to the outer side, and a limiting groove 11 is provided on one side of the movable groove 10 close to the processing groove 6 on the lower mold 1 .

[0029] In this embodiment, a side of the movable column 15 away from the positioning block 13 is fixedly connected to the limiting block 19 , and a side of the limiting block 19 away from the positioning block 13 is fixedly connected to the limiting handle 18 .

[0030] In this embodiment, the movable column 15 is located outside the positioning seat 12 and is sleeved with a return spring 21 . Both sides of the return spring 21 are fixedly connected with limit blocks 22 . The limit blocks 22 slide in the positioning seat 12 .

[0031] In this embodiment, a through hole 24 is opened inside the positioning seat 12, and the movable column 15 passes through the positioning seat 12 through the through hole. A connecting groove 23 is opened inside the positioning seat 12, and the connecting slider 20 slides in the positioning seat 12 through the connecting groove 23.

[0032] Among them, the structures in the delayed mold opening structure are all distributed based on the symmetrical structure of the lower mold 1.

[0033] It should be noted that there are eight positioning grooves 8 .

[0034] It can be understood that the number of the internal electromagnets 9 is the same as the number of the positioning slots 8 .

[0035] The working principle of the above embodiment is:

[0036] First, the worker pulls the limit handle 18 to cooperate with the limit block 19 and the return spring 21 to enable the outer electromagnet 14 on one side of the positioning block 13 to separate from the inner electromagnet 9 of the delay positioning groove 8 on the inner side of the delay positioning column 7. When the positioning block 13 is separated from the contact with the delay positioning column 7, the worker moves the upper mold 2 to a suitable position.

[0037] However, by cooperating the limit handle 18 with the limit block 19 and the return spring 21, the outer electromagnet 14 on one side of the positioning block 13 can be connected to the inner electromagnet 9 of the delay positioning groove 8 on one side of the delay positioning column 7. At this time, the electric telescopic rod 16 operates to drive the drag seat 17 to move to the point where it contacts the movable column 15, thereby providing limit support for the connected positioning block 13.

[0038] Finally, the movable column 15 slides through the through hole 24, and the connecting slider 20 on one side of the limiting block 22 slides inside the connecting slide groove 23 to cooperate with the flexible sliding of the movable column 15. The sliding of the upper mold 2 and the delayed positioning column 7 can delay the opening of the die-casting mold, thereby improving and simplifying the opening efficiency of the die-casting mold.
