Description

Technical Field

[0001] The utility model relates to the technical field of die casting, in particular to a die pre-reset detection device. Background Art

[0002] Mold die-casting reset refers to the process in which the ejection mechanism returns to the starting position accurately after ejecting the die-casting. The reset of the mold ejection mechanism is usually achieved by a reset rod, and pre-reset refers to the ejection mechanism reset process used when the die-casting action is disturbed, usually before or during mold closing. Since the mold die-casting is usually performed by a hydraulic ejector, its ejection mechanism can also be completed by a hydraulic ejector during pre-reset.

[0003] An existing mold pre-reset detection device includes the following structure: Publication number CN202021678535.1 discloses a die-casting mold pre-reset detection device, including a base, a first fixed plate fixedly connected at the top center of the base, a lower die seat is arranged on the top of the first fixed plate, a lower die groove is arranged on the top of the lower die seat, and support rods are fixedly connected to the top of the base near the four corners, the tops of the four support rods are fixedly connected to a top plate, and a lifting plate is nested and slidably connected on the four support rods below the top plate, a hydraulic cylinder is arranged at the bottom of the top plate, the driving end of the hydraulic cylinder is fixedly connected to the top of the lifting plate, and the bottom of the lifting plate is fixedly connected to a second fixed plate.

[0004] The existing technology often has the following problems when used:

[0005] The die-casting mold pre-reset device currently used may reset too quickly during the reset process due to the instantaneous force of the hydraulic ejector, resulting in a certain degree of wear on the mold surface, affecting the stability of the pre-reset and die-casting process, and even the service life of the die-casting mold; in addition, the currently used detection method cannot directly observe the pre-reset status of both sides of the mold at the same time. When the die-casting of the mold fails due to deviation in the pre-reset, it is often impossible to quickly find the fault, and it is impossible to accurately and intuitively observe whether the pre-reset is accurate before die-casting, which affects the subsequent reset and die-casting work.

[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1 and Figure 3 As shown, the embodiment of the utility model proposes a mold pre-reset detection device, including a base 1, a pre-reset component and a detection component: a bracket 2 is fixedly connected to the base 1, a hydraulic push rod 3 is fixedly connected to the bracket 2, a lower mold 4 is fixedly connected to the base 1, and a lower mold groove 13 is provided on the lower mold 4; the pre-reset component includes an upper pressing block 5 fixedly connected to the bottom end of the hydraulic push rod 3, a movable groove 6 is provided in the upper pressing block 5, an upper mold 7 is slidably connected in the movable groove 6, a compression spring 14 is connected between the upper mold 7 and the inside of the movable groove 6, two triangular sliders 8 are slidably connected in the movable groove 6, a through hole is provided on the side wall of the upper mold 7, the triangular slider 8 penetrates and is slidably connected to the through hole, two pre-reset rods 9 are fixedly connected to the lower mold 4, the tops of the two pre-reset rods 9 are inclined, the surfaces of the pre-reset rods 9 and the surfaces of the triangular sliders 8 are provided with lubricating coatings, and the inclined surfaces of the triangular sliders 8 fit the surface of the upper mold 7;

[0024] Start the hydraulic push rod 3, and drive the upper pressure block 5 to move downward through the output end of the hydraulic push rod 3. When the side of the triangular slider 8 on the upper pressure block 5 contacts the pre-reset rod 9 on the lower mold 4, the top of the pre-reset rod 9 is inclined, so that the pre-reset rod 9 squeezes the triangular slider 8, causing the triangular slider 8 to slide into the movable groove 6, and then pushes the upper mold 7 to slide elastically downward to the initial position through the compression spring 14, thereby protecting the upper mold 7 from wear, ensuring the stability of the pre-reset and die-casting process, and extending the service life of the die-casting mold.

[0025] like Figure 1 and Figure 2 As shown, the detection assembly includes a connecting rod 10 fixedly connected to the triangular slider 8, a scale ring 11 is fixedly connected to the connecting rod 10, the scale ring 11 is made of a transparent material, and a scale line is arranged on the scale ring 11, a scale 12 is fixedly connected to the upper pressing block 5, and the scale ring 11 is sleeved on the outer surface of the scale 12;

[0026] When the triangular slider 8 slides into the movable groove 6, the connecting rod 10 is driven to move, so that the connecting rod 10 pushes the scale ring 11 to slide on the scale 12. Since the scale ring 11 is made of transparent material and has scale lines, the sliding distance of the triangular slider 8 can be accurately converted and displayed on the scale 12, so that it can be more intuitive and accurate to observe whether the pre-reset is performed accurately, thereby ensuring the subsequent resetting and die-casting work.

[0027] The detailed working process of the utility model is as follows:

[0028] When in use, the hydraulic push rod 3 is started, and the upper pressing block 5 is driven to move downward through the output end of the hydraulic push rod 3. When the side of the triangular slider 8 on the upper pressing block 5 contacts the pre-reset rod 9 on the lower mold 4, the pre-reset rod 9 is inclined, so that the pre-reset rod 9 squeezes the triangular slider 8, so that the triangular slider 8 slides into the movable groove 6, and then pushes the upper mold 7 to slide elastically downward to the initial position through the compression spring 14, thereby protecting the upper mold 7 from wear, ensuring the stability of the pre-reset and die-casting process, and extending the service life of the die-casting mold;

[0029] When the triangular slider 8 slides into the movable groove 6, the connecting rod 10 is driven to move, so that the connecting rod 10 pushes the scale ring 11 to slide on the scale 12. Since the scale ring 11 is made of transparent material and has scale lines, the sliding distance of the triangular slider 8 can be accurately converted and displayed on the scale 12, so that it can be more intuitive and accurate to observe whether the pre-reset is performed accurately, thereby ensuring the subsequent resetting and die-casting work.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
