Description

Technical Field

[0001] The utility model relates to the field of die-casting molds, in particular to a die-casting mold for a lamp face ring. Background Art

[0002] Modern indoor lamps are generally embedded lamps. The most common structure of embedded lamps is the use of lamp face rings. At present, the processing of lamp face rings is usually done by die-casting, which is inseparable from the use of die-casting molds. China has authorized a utility model patent (publication number: CN221516046U) to disclose a die-casting mold. Through the provision of threaded rods, knobs, lifting frames, fixing frames, fixed pulleys one, two fixed pulleys and stabilizing rods, the connecting pipe can be limited to prevent it from offsetting during use. The fixed pulleys one and two fixed pulleys can provide good protection for the connecting pipe to prevent wear during use, reduce damage caused by wear, and make the use effect better.

[0003] However, the above device still has some shortcomings when in use: specifically, both ends of the feed pipe in the existing injection mold often have flanges, which are connected to the upper mold and the feeding device respectively through the flanges. In the prior art, the distance between fixed pulley 1 and fixed pulley 2 is fixed. Due to the fixed position of fixed pulley 1 and fixed pulley 2, the presence of the flange makes it inconvenient to disassemble the feed pipe. Therefore, in response to the above situation, a die-casting mold for a lamp face ring is proposed. Utility Model Content

One end of the screw rod is rotatably connected to the second C-shaped plate on the same horizontal plane. A support rod is provided between the two first C-shaped plates. A connecting rod is fixedly connected between the two second C-shaped plates.

[0008] When the two guiding mechanisms are used in cooperation, the two guiding wheels on the same horizontal plane are in rolling contact with the outer wall of the connecting pipe, playing a guiding role for the connecting pipe.

[0009] Preferably, the guiding mechanism further includes a support seat. The support seat is fixed on the top of the top seat. The first C-shaped plate is fixed on the top of the support seat.

[0010] Preferably, sliding grooves are provided on both sides of the inner wall of the first C-shaped plate. Protrusions are fixedly provided on both sides of the outer wall of the second C-shaped plate. The protrusions are slidably fitted with the sliding grooves.

[0011] Preferably, round holes are provided on both sides of the outer wall of the second C-shaped plate. Both ends of the guiding wheel are in clearance fit with the round holes.

[0012] Preferably, the top seat includes a cross plate. Vertical rods are provided at the four corners of the bottom of the cross plate. The bottoms of the four vertical rods are fixedly connected to the top of the base.

[0029] Among them, the top seat 3 includes a cross plate, vertical rods are arranged at the four corners of the bottom of the cross plate, the bottoms of the four vertical rods are fixedly connected to the top of the base 1, a hollow hole is formed through the top of the cross plate, a cylinder is arranged on the top of the cross plate, and the moving end of the cylinder passes through the hollow hole and is fixedly connected to the upper mold 4.

[0030] A through groove 301 is formed in the top of the top seat 3, a connecting pipe 5 is arranged on the upper mold 4, one end of the connecting pipe 5 passes through the through groove 301 and extends upward, and a guiding mechanism 6 is arranged on the top of the top seat 3, and there are two guiding mechanisms 6.

[0031] The guiding mechanism 6 includes two first C-shaped plates 8, a second C-shaped plate 11 is slidably fitted on each first C-shaped plate 8, a guiding wheel 12 is rotatably connected to each second C-shaped plate 11, and a screw rod 10 is threadedly fitted on one of the first C-shaped plates 8. Specifically, a threaded hole 802 is formed in one of the first C-shaped plates 8, the screw rod 10 is threadedly fitted in the threaded hole 802, one end of the screw rod 10 is rotatably connected to the second C-shaped plate 11 on the same horizontal plane through a bearing, a support rod 9 is arranged between the two first C-shaped plates 8, and a connecting rod 14 is fixedly connected between the two second C-shaped plates 11.

[0032] Among them, circular holes are formed on both sides of the outer wall of the second C-shaped plate 11, and both ends of the guiding wheel 12 are in clearance fit with the circular holes.

[0033] When the two guiding mechanisms 6 are used in combination, the two guiding wheels 12 on the same horizontal plane are in rolling contact with the outer wall of the connecting pipe 5, playing a guiding role for the connecting pipe 5.

[0034] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the guiding mechanism 6 further includes a support seat 7, the support seat 7 is fixed on the top of the top seat 3, and the first C-shaped plate 8 is fixed on the top of the support seat 7.

[0035] In this embodiment, when in use, first connect an external power supply and a switch to the electrical equipment in this device, start the cylinder to drive the upper mold 4 to move downward, so that the upper mold 4 and the lower mold 2 can be closed, and then use an external device to guide the molten metal into the interior of the upper mold 4 through the connecting pipe 5 to complete the die-casting work of the lamp face ring.

[0036] In this embodiment, by providing the support seat 7, it is used to support the first C-shaped plate 8.

[0037] Refer to Figure 2 、 Figure 3 and Figure 4 On both sides of the inner wall of the first C-shaped plate 8, sliding grooves 801 are provided. On both sides of the outer wall of the second C-shaped plate 11, bumps 13 are fixed. The bumps 13 are slidably engaged with the sliding grooves 801.

After the screw 10 rotates counterclockwise, it drives the second C-shaped plate 11 to slide towards the end away from the connecting pipe 5, that is, the bumps 13 on the second C-shaped plate 11 slide in the sliding grooves 801. The sliding of the bottom second C-shaped plate 11, under the connection of the connecting rod 14, synchronously makes the top second C-shaped plate 11 slide, so that the guide wheels 12 on the two second C-shaped plates 11 are no longer in contact with the connecting pipe 5. Similarly, continue to complete the operation of the other screw 10. After the two ends of the connecting pipe 5 are disassembled, the connecting pipe 5 can be removed through the through groove 301 for replacement or maintenance.
