Description

Technical Field

[0001] The utility model relates to the field of injection molding machines, in particular to a sheet metal protective cover which is convenient for filling gaps. Background Art

[0002] refer to Figures 1-3 After the production of the sheet metal parts is completed, the edges need to be bent to form a sheet metal protective cover 1. After the sheet metal protective cover 1 is installed on the injection molding machine, in order to facilitate the subsequent inspection and maintenance of the components on the injection molding machine, a gap 2 needs to be opened before the edge of the sheet metal protective cover 1 is bent. After the inspection is completed, a filling plate 3 needs to be installed at the gap 2. Only after the gap is filled, the sheet metal protective cover 1 has the function of protecting the local part of the injection molding machine.

[0003] The existing gap filling plate 3 and the sheet metal protective cover 1 are produced independently and then assembled. There are often assembly errors during assembly, resulting in assembly failure. The reasons for the errors include the following: 1. Due to the existence of the folded edge of the sheet metal protective cover 1, there are multiple bends at the gap 2, and the gap filling plate 3 must also have corresponding bends, resulting in very high precision requirements during the production process, and it is difficult to ensure a complete match; 2. During the transportation of the sheet metal protective cover 1, the gap 2 is a weak point under stress and is prone to deformation. Once deformed, it is bound to be difficult to adapt to the gap filling plate 3. Utility Model Content

A filling plate is fixed on the main plate, which extends to the protective cover body and a matching structure is provided between the filling plate and the protective cover body so that the two can be matched with a detachable structure in the future.

[0007] Adopting the above scheme, the filler plate can be installed to the main plate on the body of the protective cover before the edge of the body of the protective cover is bent, and then the filler plate can be bent together with the edge of the body of the protective cover, thereby reducing the error probability between the filler plate and the body of the protective cover after bending, improving the adaptability of the two, and when the filler plate is installed on the main plate, the rigidity of the main plate is also improved, thereby reducing the probability of deformation of the main plate of the body of the protective cover during transportation, and even if the main plate is deformed during transportation of the protective cover body, the filler plate will deform together with the main plate, thereby reducing the error between the filler plate and the body of the protective cover when the filler plate is installed again between the two cutting grooves, and the matching structure is arranged to be installed to the body of the protective cover again after the filler plate and the main plate are removed, thereby protecting the injection molding machine.

[0008] Preferably, the matching structure includes a socket arranged on the filler plate extending to the body of the protective cover and a fixing hole arranged on the body of the protective cover and opposite to the socket when the filler plate is installed to the main plate.

[0010] Preferably, the filler plate extends to the body of the protective cover on any opposite two sides or four sides of the main plate.

[0011] Adopting the above scheme, the filler plate extending to two sides or four sides of the main plate can make the connection between the filler plate and the body of the protective cover more stable when the filler plate and the main plate are removed from the body of the protective cover and installed again to the body of the protective cover.

[0012] Preferably, the cutting groove is in a straight line, and the main plate is in a regular polygon (N≥3).

[0013] Adopting the above scheme, the cutting groove in a straight line makes the shape of the main plate a regular polygon, thereby facilitating the filler plate to be removed from the body of the protective cover together with the main plate after being installed on the main plate, thereby improving the adaptability of the filler plate and the body of the protective cover when the body of the protective cover is installed on the injection molding machine.

[0014] Preferably, the cutting groove is in an arc line, and the main plate is in a circle or an ellipse.

[0015] By the above scheme, the arc-shaped cutout makes the shape of the main plate block circular or elliptical, so that the filling plate can be removed from the protective cover body together with the main plate block after being installed on the main plate block, thereby improving the adaptability of the filling plate and the protective cover body when the protective cover body is installed on the injection molding machine.

[0016] Preferably, the cutout is provided with at least two and is uniformly distributed around the circumference of the main plate block.

[0017] By the above scheme, the at least two cutouts uniformly arranged around the circumference of the main plate block of the protective cover body can facilitate the operator to remove the filling plate from the protective cover body together with the main plate block after the filling plate is installed on the main plate block.

[0018] Preferably, the cutout is provided with two, and the two cutouts are in the shape of "concave" with the openings facing each other.

[0019] By the above scheme, the two cutouts in the shape of "concave" with the openings facing each other can also facilitate the operator to remove the filling plate from the protective cover body together with the main plate block when the filling plate is installed on the main plate block.

[0020] Preferably, the filling plate is provided with a mounting component facilitating the fixation of the filling plate to the main plate block before being removed.

[0021] Preferably, the mounting component includes a plurality of welding holes arranged at intervals on the filling plate.

[0022] By the above scheme, the welding holes arranged on the filling plate can facilitate the operator to fix the filling plate to the main plate block through the welding holes when the filling plate is installed on the main plate block.

[0023] The utility model discloses a filling plate and a protective cover body, and the filling plate is arranged on the main plate block of the protective cover body, and the filling plate is provided with a cutout, and the cutout is arranged on the main plate block and is arranged in the shape of arc.
