Description

Technical Field

[0001] This utility model relates to the field of safety protection door technology, specifically a safety protection door for a foam molding machine. Background Technology

[0002] Safety doors play a crucial role in the operation and maintenance of foam molding machines. They not only effectively isolate the operating area and protect operators from injuries caused by moving parts, but also provide convenient access when the machine needs maintenance. Traditional foam molding machine safety door designs typically include an upper support frame, a lower support frame, and a first and second safety door mounted on these two support frames respectively. These safety doors are securely connected to the support frames via specific connecting components, such as convex anti-slip blocks and sliding rods. Specifically, the convex anti-slip blocks are usually designed to match the shape of the safety door edge and are fixed to the safety door with bolts, while the sliding rods pass through pre-drilled holes on the support frame, mate with corresponding structures on the convex anti-slip blocks, and are then locked with nuts, thereby ensuring the stability and safety of the safety doors.

[0003] However, when a foam molding machine needs inspection or maintenance, the traditional safety gate disassembly process is relatively cumbersome and poses potential risks. Operators must first loosen the bolts on the convex anti-slip block and the nuts on the sliding rod, and then remove the convex anti-slip block and sliding rod from the safety gate and support frame to complete the disassembly. This process is not only time-consuming and labor-intensive, but also increases operational complexity. More importantly, because the convex anti-slip block, sliding rod, and related bolts and nuts need to be completely separated during disassembly, these parts are easily lost or damaged after disassembly, causing inconvenience for subsequent reinstallation. Therefore, we propose a safety gate for foam molding machines to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a safety gate for a foam molding machine, which solves the problems mentioned in the background section.

[0008] A safety gate for a foam molding machine includes two support frames. Each support frame has two open-ended grooves on one side, each groove having two sliders. Two safety gates are positioned between the two support frames. One side of each safety gate is fixedly connected to the corresponding side of a slider. Two reinforcing plates are fixedly connected between the two support frames. One of the reinforcing plates has a cavity. A lead screw is rotatably connected between the inner walls of the cavity. The end of the lead screw extends beyond one of the reinforcing plates and has a knob welded to it. Four guide rods are welded to one inner wall of the cavity. A common limiting plate is slidably connected to two adjacent guide rods. Two springs are fixedly connected between one side of the limiting plate and one inner wall of the cavity. The springs are movably sleeved on the corresponding guide rods. A movable plate is fixedly connected between the two limiting plates and is threadedly connected to the lead screw.

[0009] Furthermore, two rectangular holes are formed on the inner wall of the other side of the cavity, and the inner wall of the rectangular holes is slidably connected to the outer side of the corresponding limiting plate.

[0010] Furthermore, the protective door has two mounting holes, and a protective net is fixedly connected to the inner wall of the mounting holes.

[0011] Furthermore, a handle is fixedly connected to the front side of one of the two protective doors.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a safety door for a foam molding machine, which has the following beneficial effects:

[0016] This invention utilizes a rotary knob, which, via a lead screw, moves a movable plate. The movable plate then moves a limiting plate, which slides on a corresponding guide rod and compresses a spring. This causes the limiting plate to move into the cavity, thus removing it from the protective door's position. The protective door is then moved, causing the corresponding slider to disengage from its groove, allowing the door to be removed. Disassembly is seamless and does not result in the loss of any parts. The operation is simple and convenient. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] like Figure 1-4As shown in the figure, an embodiment of the present invention provides a safety guard door for a foam molding machine, comprising two support frames 1. Two open-ended sliding grooves 2 are formed on one side of each support frame 1, and two sliders 3 are mounted on the sliding grooves 2. Two safety guard doors 4 are positioned between the two support frames 1, with one side of each safety guard door 4 fixedly connected to one side of a corresponding slider 3. Two reinforcing plates 5 are fixedly connected between the two support frames 1. One of the reinforcing plates 5 has a cavity 6. A lead screw 7 is rotatably connected between the inner walls of both sides of the cavity 6. The end of the lead screw 7 extends beyond one of the reinforcing plates 5 and is welded with a knob 9. Four guide rods 10 are welded to one inner wall of the cavity 6, and the same limiting plate 11 is slidably connected to two adjacent guide rods 10. Two springs 12 are fixedly connected between one side of the positioning plate 11 and the inner wall of one side of the cavity 6. The springs 12 are movably sleeved on the corresponding guide rods 10. A movable plate 8 is fixedly connected between the two limiting plates 11. The movable plate 8 is threadedly connected to the lead screw 7. During maintenance, the knob 9 is rotated in the forward direction. The knob 9 drives the movable plate 8 to move through the lead screw 7. The movable plate 8 drives the limiting plate 11 to move. The limiting plate 11 slides on the corresponding guide rod 10 and compresses the springs 12, so that the limiting plate 11 moves into the cavity 6, so that the limiting plate 11 no longer limits the protective door 4. Then the protective door 4 is moved. The protective door 4 drives the corresponding slider 3 to disengage from the corresponding slide groove 2, so that the protective door 4 can be removed. When disassembling, no parts will be lost, and the operation is simple and convenient.

[0025] In some embodiments, two rectangular holes 13 are formed on the inner wall of the other side of the cavity 6, and the inner wall of the rectangular holes 13 is slidably connected to the outer side of the corresponding limiting plate 11.

[0026] In some embodiments, the protective door 4 has two mounting holes 14, and a protective net 15 is fixedly connected to the inner wall of the mounting holes 14. The mounting holes 14 are provided for installation.

[0027] In some embodiments, a handle 16 is fixedly connected to the front side of one of the two protective doors 4.

[0028] In some embodiments, the movable plate 8 is provided with a threaded hole, and the movable plate 8 is threadedly connected to the lead screw 7 through the threaded hole. Under the biting force of the threaded hole and the lead screw 7, the movable plate 8 can be fixed after moving to a suitable position.

[0029] In some embodiments, a circular hole is provided on the inner wall of the other side of the cavity 6, and a bearing is fixedly connected to the inner wall of the circular hole. The inner ring of the bearing is welded to the outer side of the lead screw 7. By welding, the bearing and the lead screw 7 are more securely fixed.

[0030] The working principle or structural principle is as follows: During maintenance, turn knob 9 forward. Knob 9 moves movable plate 8 via lead screw 7, which in turn moves limit plate 11. Limit plate 11 slides on the corresponding guide rod 10 and compresses spring 12, causing limit plate 11 to move into cavity 6. This removes limit plate 11 from the protective door 4. Then, move the protective door 4, causing the corresponding slider 3 to disengage from the corresponding slide groove 2, allowing the protective door 4 to be removed for mechanical maintenance. After maintenance, place slider 3 back into the corresponding slide groove 2, and then turn knob 9 in reverse. Knob 9 moves movable plate 8 via lead screw 7, which in turn moves limit plate 11. Limit plate 11 slides on guide rod 10, causing it to move out of cavity 6. Limit plate 11 then limits the protective door 4, preventing the loss of parts during disassembly. The operation is simple and convenient.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
