Description

Technical Field

[0001] The utility model relates to the field of injection molding machine accessories, in particular to a foldable working platform of an injection molding machine. Background Art

[0002] The work platform is usually equipped on large equipment such as injection molding machines and machine tools, so that operators can stand on it to observe the operation of the equipment or perform maintenance on the equipment. Figure 1-2 As shown, it includes more than two sets of platform frames fixed by screws and platform ladders fixed to the platform frames at both ends by screws for climbing onto the platform frames. One side of the platform frame and the platform ladder is in contact with the injection molding machine, and a guardrail is vertically fixed on the side of the platform frame away from the injection molding machine to prevent the operator from falling.

[0003] During the storage of the above-mentioned working platform, since the guardrail is fixedly arranged on the platform frame and cannot be folded, the volume of the disassembled platform frame is too large, resulting in the disadvantage of low utilization rate of the factory space. Utility Model Content

[0004] The utility model aims at the disadvantages that the existing guardrails are vertically fixed on the platform frame, resulting in excessive storage volume and reduced plant space utilization, and provides a foldable working platform for an injection molding machine which can significantly reduce the storage volume.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] The foldable working platform of the injection molding machine includes a platform frame formed by splicing and fixing at least two groups of platform frames, platform ladders located at both ends of the platform frame for climbing onto the platform frame, and guardrails arranged on one side of each group of platform frames. A rotating limiting component is arranged between the guardrail and the platform frame, which can allow the guardrail to be flipped relative to the platform frame to be perpendicular to the upper end of the platform frame or horizontally stacked on the upper end of the platform frame and to be limited after flipping.

[0007] By adopting the above scheme, the guardrail is connected to the platform frame through a rotating limiting component. The guardrail can be rotated relative to the platform frame and can also be limited after rotation. When the guardrail is rotated to be vertically located on the upper end face of the platform frame, it is in a protective state and can play a blocking role; when the guardrail is rotated to be stacked on the upper end of the platform frame, it is in a folded storage state, which can significantly reduce the volume of the platform frame when it is stored.

[0008] Preferably, the rotation limiting component includes a mounting base fixed to the upper end of the side wall of the platform frame, a mounting plate protruding parallel to the upper end of the mounting base and having a mounting hole, and a connecting bolt inserted into the mounting hole. The lower end of the guardrail is inserted between the mounting holes and the guardrail is provided with a matching hole through which the connecting bolt can rotate. The connecting bolt is matched with a locking nut that drives the mounting plate to clamp to limit the rotation of the guardrail.

[0009] By adopting the above scheme, when the connecting bolt and the locking nut are tightly matched, the two mounting plates can be clamped on the guardrail to achieve clamping, thereby limiting the rotation of the guardrail relative to the mounting base; when the locking nut is screwed outward until the two mounting plates no longer clamp the guardrail, the guardrail can be flipped around the locking nut, thereby adjusting the angle of the guardrail relative to the platform frame, thereby achieving the deployment or folding of the guardrail.

[0010] Preferably, a matching structure is provided between the mounting base and the guardrail to prevent the guardrail from being released from a locked state under the action of an external force.

[0011] With the above solution, the guardrail and the mounting base are limited only by connecting bolts and locking nuts, which is not reliable enough. Once an excessively large external force hits the guardrail, there is a probability that the guardrail will flip over. Therefore, it is necessary to add a matching structure that can significantly reduce the probability of the guardrail flipping.

[0012] Preferably, the mating structure includes a slot recessed at the upper end of the mounting base into which the lower end of the guardrail can be inserted, and the mating hole is a first waist-shaped hole that allows the guardrail to be vertically raised and lowered and can be partially inserted into the slot when descending, and has a mating distance with the upper end of the mounting base when rising to allow the guardrail to flip.

[0013] By adopting the above scheme, a first waist-shaped hole is set on the guardrail, and the guardrail can be raised and lowered when the guardrail is vertical to the platform frame. A recessed slot is provided at the upper end of the mounting base. After the lower end of the guardrail is inserted into the slot, the connecting bolts and the locking nuts are tightened, and the guardrail will be firmly limited on the mounting base, significantly increasing the protection performance of the guardrail.

[0014] Preferably, each set of platform frames has at least one independent guardrail, and at least two sets of rotation limiting components are arranged in parallel between each guardrail and the platform frame.

[0015] Preferably, adjacent guardrails are detachably fixedly connected via a connector.

[0016] Preferably, the connecting piece is a guardrail pipe clamp assembly, which includes a mounting plate located on the outer wall of the adjacent guardrails and two pipe clamps respectively clamped on a guardrail and fixed to the mounting plate at both ends by screws.

[0017] By adopting the above scheme, adjacent guardrails are connected by fixing with pipe clamps and mounting plates. Even if there is a problem with the rotation limit component of a local guardrail, other guardrails can be used for reinforcement to further increase the protective performance of the guardrail.

[0018] Preferably, the platform ladder includes a ladder side panel which is arranged in parallel and inclined and has one end inclined upward and detachably fixed to one end of the platform frame, a plurality of pedals fixed to the ladder side panel at both ends, and a ladder railing vertically fixed on the ladder side panel on the side close to the guardrail.

[0019] By adopting the above solution, the ladder railing can protect the distance before the operator climbs onto the platform frame.

[0020] The utility model has significant technical effects due to the adoption of the above technical solutions:

[0021] 1. The guardrail is connected to the platform frame through a rotation limit component. The guardrail can be rotated relative to the platform frame and can be limited after rotation. When the guardrail is rotated to be vertically located on the upper end surface of the platform frame, it is in a protective state and can play a blocking role; when the guardrail is rotated to be stacked on the upper end of the platform frame, it is in a folded storage state, which can significantly reduce the volume of the platform frame when it is stored;

[0022] 2. Add a matching structure, that is, set a first waist-shaped hole on the guardrail and a recessed slot at the upper end of the mounting base. When the guardrail is vertical to the platform frame, the guardrail can be raised and lowered. After the lower end of the guardrail is inserted into the slot, the connecting bolts and locking nuts are tightened, and the guardrail will be firmly limited on the mounting base, which significantly increases the protection performance of the guardrail.
