Description

Technical Field

[0001] The utility model relates to the technical field of die casting molds, in particular to a die casting mold insert. Background Art

[0002] Die-casting molds consist of a core or cavity, a mold base, and accessories. Mold inserts are the most common structure in precision molds, and most consumer electronics products require the disassembly of numerous inserts or components. However, due to the unique shapes and small sizes of some product structures, the processing costs of the insert hangers are high, and the actual precision after molding is poor. The hangers between inserts are prone to interference due to the limited space.

[0003] According to a disclosed die-casting mold insert (CN 220028638 U), it includes a latch end and an arc-shaped end. The latch end is provided with a plurality of latch holes. The arc-shaped end and the latch end are integrated. The latch end is fixed by a latch type instead of a hanging table type to form a match with the mold.

[0004] However, in the above design, it is difficult to achieve that when the brush is subjected to force and makes reciprocating linear motion on the top of the mold insert, the pin end, the arc end and other components cooperate with each other, and it is difficult to adhere to the top of the mold insert. As a result, the dust on the top of the mold insert cannot be removed, and the mold insert cannot function normally. This needs to be improved. Utility Model Content

[0005] The utility model provides a die-casting die insert, which solves the die-casting die insert problem in the related art.

[0007] According to the above design scheme, the top of the push rod is fixedly connected to a force block, the side of the force block is fixedly connected to a scraper, and a brush is provided at the bottom of the scraper. This design is conducive to driving the force block to perform reciprocating linear motion when the push rod is forced to perform reciprocating horizontal linear motion.

[0008] According to the above design scheme, the force-bearing block is slidably connected to the inner wall of the groove, and two scrapers are provided, which are symmetrical to each other along the vertical central axis of the bottom of the force-bearing block. This design is beneficial for the force-bearing block to make reciprocating horizontal linear motion under force, and the scraper also moves accordingly.

[0009] According to the above design scheme, a clamping device is provided on the top of the base, and the clamping device includes a fixed plate, which is fixedly connected to the top of the base. The side of the fixed plate is rotatably connected to a rotating shaft, and the circumferential surface of the rotating shaft is fixedly connected to a rectangular plate.

[0013] According to the above design scheme, the side cross-section of the collecting plate is set to be U-shaped, the inner wall length of the collecting plate is adapted to the mold insert, and the force-bearing plate is set to be L-shaped and in contact with the top of the mold insert. Such a design is beneficial when the dust is brushed by the brush, and the dust is pushed by the brush and falls into the inside of the collecting plate.

[0014] According to the above design scheme, there are several springs, which are symmetrical to each other along the vertical center axis of the base. Such a design is beneficial for the load-bearing plate to be able to move upward due to the elastic force of the springs when the load-bearing plate is subjected to tension.

[0015] According to the above design scheme, the bottom of the pull plate is set to an adaptive arc surface. There are two pull plates, which are symmetrical to each other along the vertical center axis of the base.

[0017] The utility model realizes that when the push rod, the force block, the scraper, the brush and other components cooperate with each other, the brush is pressed against the top of the mold insert to remove the dust on the top of the mold insert when the brush is forced to make reciprocating linear motion. When the dust is loosened by the brushing, the dust falls into the inside of the collection plate due to the thrust of the brush, which saves the working time of the staff and enables the dust removal device to complete its work smoothly.

[0018] In the utility model, the fixed plate, the rotating shaft, the rectangular plate, the rectangular groove and other components cooperate with each other, so that when the height of the mold insert is greater than the height of the rectangular plate, the staff can pull the pull plate upward, so that the pull plate is displaced upward by the spring force, and thus clamped on the top of the mold insert. While clamping the mold insert, the clamping device can adapt to different mold inserts to clamp and fix them, thereby improving the work efficiency of the staff, allowing the clamping device to be recycled, and reducing costs.

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figures 1 and 2 This embodiment proposes a die-casting mold insert, including a base 1 and a mold insert 2. The mold insert 2 is arranged on the top of the base 1. A semicircular groove 3 is opened on the top of the mold insert 2. A dust removal device 4 is arranged inside the mold insert 2; the dust removal device 4 includes a groove 41. The groove 41 is opened on the top of the mold insert 2. An electric telescopic rod 42 is provided on the inner wall of the groove 41. The telescopic end of the electric telescopic rod 42 is fixedly connected to a push rod 43.

[0029] The top of the push rod 43 is fixedly connected to a force block 44, the side of the force block 44 is fixedly connected to a scraper 45, and the bottom of the scraper 45 is provided with a brush 46. This design is conducive to driving the force block 44 to perform reciprocating linear motion when the push rod 43 is forced to perform reciprocating horizontal linear motion.

[0030] The force block 44 is slidably connected to the inner wall of the groove 41. Two scrapers 45 are provided, and are symmetrical to each other along the vertical center axis of the bottom of the force block 44. This design is beneficial for the scraper 45 to move accordingly when the force block 44 is subjected to force and performs reciprocating horizontal linear motion.

[0031] In this embodiment, first, when the mold insert 2 is placed in the mold, there must be no residual dust on the surface of the mold insert 2. At this time, the external power supply is started to start the electric telescopic rod 42 to start reciprocating horizontal linear motion. When the electric telescopic rod 42 makes reciprocating linear motion, it drives the push rod 43 fixed at the telescopic end of the electric telescopic rod 42 to make reciprocating horizontal linear motion, prompting the force-bearing block 44 fixed on the top of the push rod 43 to be forced to make reciprocating horizontal linear motion through the groove 41. When the force-bearing block 44 is forced to make reciprocating horizontal linear motion, the fixed The scraper 45 fixed on the side of the force block 44 makes a reciprocating horizontal linear motion. When the scraper 45 makes a reciprocating horizontal linear motion, it prompts the brush 46 to make a reciprocating horizontal linear motion. When the brush 46 is forced to make a reciprocating linear motion on the top of the mold insert 2, the brush 46 sticks to the top of the mold insert 2 to remove the dust on the top of the mold insert 2. When the dust is loosened by the brushing of the brush 46, it falls into the inside of the collecting plate 58 by the thrust of the brush 46, saving the working time of the staff and allowing the dust removal device 4 to complete its work smoothly.

[0032] Example 2

[0033] like Figures 3 to 5 Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a clamping device 5 is provided on the top of the base 1, and the clamping device 5 includes a fixed plate 51, and the fixed plate 51 is fixedly connected to the top of the base 1. The side of the fixed plate 51 is rotatably connected to the rotating shaft 52, and the circumferential surface of the rotating shaft 52 is fixedly connected to the rectangular plate 53. This design is conducive to the rectangular plate 53 being able to perform arc motion under the force of the rotating shaft 52.

[0034] A rectangular groove 54 is provided at the top of the rectangular plate 53, and a spring 55 is fixedly connected to the inner wall of the rectangular groove 54. The end of the spring 55 away from the rectangular groove 54 is fixedly connected to a force-bearing plate 56, and the side of the force-bearing plate 56 is fixedly connected to a pulling plate 57. The side of the mold insert 2 is fixedly connected to a collecting plate 58. This design is advantageous in that when the height of the mold insert 2 is consistent with the height of the rectangular plate 53, the spring 55 is placed on the inner wall of the rectangular groove 54, and the force-bearing plate 56 and the mold insert 2 are in contact with each other.

[0035] The bottom of the force-bearing plate 56 contacts the top of the rectangular plate 53. There are two force-bearing plates 56, which are symmetrical to each other along the vertical center axis of the bottom of the base 1. This design is conducive to clamping the mold insert 2 when the force-bearing plate 56 is forced to move upward.

[0036] There are two brushes 46, which are symmetrical to each other along the vertical center axis of the bottom of the force-bearing block 44. The brushes 46 are adapted to the mold insert 2. This design is beneficial for the brushes 46 to move accordingly when the scraper 45 is forced to make reciprocating horizontal linear motion.

[0037] The side cross-section of the collecting plate 58 is set to be U-shaped, the inner wall length of the collecting plate 58 is adapted to the mold insert 2, and the force plate 56 is set to be L-shaped and in contact with the top of the mold insert 2. This design is beneficial when the dust is brushed by the brush 46, the dust is pushed by the brush 46 and falls into the inside of the collecting plate 58.

[0038] There are a plurality of springs 55 , which are symmetrical with each other along the vertical center axis of the base 1 . This design is advantageous in that when the force-bearing plate 56 is subjected to tension, the force-bearing plate 56 can be displaced upward by the elastic force of the springs 55 .

[0039] The bottom of the pull plate 57 is set to an adaptive arc surface. There are two pull plates 57, which are symmetrical to each other along the vertical center axis of the base 1. When the height of the mold insert 2 is higher than the height of the rectangular plate 53, the staff can clamp the mold insert 2 by pulling the pull plate 57.

[0040] In this embodiment, in the dust removal device 4, after the dust removal device 4 completes its work, in order to fix the mold insert 2 in the mold while facilitating disassembly by the staff, when the mold insert 2 is placed above the base 1, the staff rotates the pull plate 57 so that the pull plate 57 drives the force plate 56, thereby causing the rectangular plate 53 to move in an arc shape under the force of the rotating shaft 52. When the height of the mold insert 2 is greater than the height of the rectangular plate 53, the staff can pull the pull plate 57 upward so that the pull plate 57 is forced to move upward through the spring 55, thereby clamping it on the top of the mold insert 2. While clamping the mold insert 2, the clamping device 5 can adapt to different mold inserts 2 to clamp and fix it, thereby improving the work efficiency of the staff, enabling the clamping device 5 to be recycled, and reducing costs.
