Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet for an injection molding machine with a flip-type electrical appliance bottom plate mounting structure. Background Art

[0002] The power distribution cabinet of the injection molding machine is an integral part of the injection molding machine. The volume of the power distribution cabinet depends on the volume of the injection molding machine. The specific structure can refer to the Chinese patent publication No. CN209516339U, which discloses a power distribution cabinet for an injection molding machine. It generally includes a box body and electrical components arranged in the box body. The side wall of the box body is an opening. Each power distribution cabinet is equipped with a vertical flat electrical installation base plate, which is opposite to the opening, and all electrical components are installed on the electrical installation base plate.

[0003] When the function configuration of the machine increases, the existing single-plane electrical installation baseboard layout will be very compact, often resulting in insufficient space, and the cable routing will be very crowded, greatly reducing the heat dissipation and current carrying capacity of the strong wires. In this case, the existing method is to change the appearance of the distribution cabinet, increase the height or width or increase the number of cabinets, but this solution has the disadvantages of high cost and affecting the appearance of the entire equipment. Utility Model Content

[0004] The utility model aims at solving the problem that when the volume of the existing injection molding machine power distribution cabinet is insufficient, the volume can only be increased by raising, widening or adding cabinets, which has the disadvantages of high cost and affecting the appearance of the equipment. The utility model provides a power distribution cabinet for the injection molding machine with a flip-type electrical bottom plate installation structure, which does not significantly increase the installation cost and can significantly expand the installation volume of electrical components.

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

[0006] A power distribution cabinet for an injection molding machine with a flip-type electrical bottom plate installation structure comprises a cabinet body and an electrical installation bottom plate arranged in the cabinet body, a bottom plate installation structure which does not interfere with the installation of electrical components on the electrical installation bottom plate while increasing the installation capacity of the electrical components is arranged in the cabinet body, and the bottom plate installation structure comprises a rotating bottom plate hinged on the side wall of the power distribution cabinet, a column vertically fixed to the bottom of the cabinet body, and a locking mechanism which limits the rotation of the rotating bottom plate when it rotates to be flush with the column.

[0007] By adopting the above scheme, a rotating base plate is added in the cabinet, and electrical components can be installed on both sides of the rotating base plate. The rotating base plate can be flipped to expose the electrical installation base plate, and it is also convenient to disassemble and assemble the electrical components installed on the side of the rotating base plate opposite to the electrical installation base plate. The locking mechanism can keep the rotating base plate in a state of being stored in the cabinet, ensuring that the electrical components on the rotating base plate are in a continuous and stable installation state. The setting cost of this rotating base plate is low, and the installation volume of the electrical components will not change the appearance of the cabinet while increasing the electrical component installation volume, which is convenient for maintaining the electrical components on the electrical installation base plate and the rotating base plate.

[0008] Preferably, the locking mechanism includes a lock hook fixed on the column and a lock buckle hinged on the rotating base plate and capable of being buckled on the lock hook.

[0009] By adopting the above solution, the rotation of the rotating base plate can be limited by locking the lock hook with the lock buckle.

[0010] Preferably, a limiting component is provided on the rotating base plate for limiting the rotating base plate from rotating in the opposite direction after the rotating base plate rotates outward to a specified angle.

[0011] By adopting the above solution, when it is necessary to maintain the electrical installation base plate or the electrical components on the rotating base plate close to the electrical installation base plate, the limiting component can ensure that the rotating base plate is in an open state.

[0012] Preferably, the limiting component includes a vertically liftable pin fixed on a side of the rotating base plate away from the electrical appliance mounting base plate. When the rotating base plate rotates outward until the pin is outside the cabinet, the pin descends and the side wall of the pin abuts against the lower outer wall of the cabinet.

[0013] With the above solution, when the rotating bottom plate is rotated outward to be partially exposed outside the cabinet, the latch drops, and the side wall of the latch abuts against the outer wall below the cabinet opening to achieve positioning. There is no need to provide an additional slot for the latch in the cabinet, and the arrangement is convenient.

[0014] Preferably, the four sides of the rotating base plate are vertically folded toward one side of the electrical appliance installation base plate to form a reinforced folded edge for increasing the longitudinal deformation resistance of the rotating base plate.

[0015] With the above solution, the electrical components are arranged on the side wall of the rotating base plate. Therefore, it is particularly important to improve the longitudinal deformation resistance of the rotating base plate. Strengthening the folding edge setting can increase the "thickness" of the rotating base plate. This setting significantly improves the longitudinal deformation resistance of the rotating base plate.

[0016] Preferably, the rotating bottom plate is hinged to an "L"-shaped mounting plate through a hinge, and one side of the "L"-shaped mounting plate perpendicular to the hinge is fixedly connected to the side wall of the cabinet.

[0017] With the above solution, the "L"-shaped mounting plate plays a connecting role, making it easy to rotate the bottom plate to achieve hinged connection with the cabinet body.

[0018] Preferably, at least two waist-shaped grooves for adjusting the installation position of the rotating base plate on the cabinet are arranged at intervals on one side of the "L"-shaped installation plate perpendicular to the installation hinge.

[0019] By adopting the above solution, the setting of the waist-shaped groove can fine-tune the setting position of the rotating bottom plate in the cabinet body and eliminate installation errors.

[0020] The utility model has remarkable technical effects due to the adoption of the above technical scheme: a rotating base plate is added in the cabinet, electrical components can be installed on both sides of the rotating base plate, the rotating base plate can be flipped over to expose the electrical installation base plate, and it is also convenient to disassemble and assemble the electrical components installed on the side of the rotating base plate facing the electrical installation base plate, the locking mechanism can be used to keep the rotating base plate in a state of being stored in the cabinet, ensuring that the electrical components on the rotating base plate are in a continuous and stable installation state, the latch can be used to keep the rotating base plate in an open state, which is convenient for operators to disassemble or maintain the electrical components, the rotating base plate has a low setting cost, increases the installation volume of the electrical components without changing the appearance of the cabinet, and is convenient for maintaining the electrical installation base plate and the electrical components on the rotating base plate.

[0028] The bottom plate installation structure includes a rotating bottom plate 3, the size of the rotating bottom plate 3 is 427mm x 450mm, 3 rows of electrical components can be placed, which is 32% larger than the original installation space. The thickness of the rotating base plate 3 is 1.5mm. The four sides of the rotating base plate 3 are vertically folded to form a reinforcing folded edge 31. The reinforcing folded edges 31 on both sides of the rotating base plate 3 are vertically folded to form an installation folded edge 32 parallel to the rotating base plate 3. The rotating base plate 3 is hinged on the side wall of the cabinet 1 with the reinforcing folded edge 31 facing the electrical installation base plate 2. The installation folded edge 32 on one side of the rotating base plate 3 is hinged to an "L"-shaped mounting plate 5 through a hinge 8. The hinge 8 is longitudinally provided with two groups. The side of the "L"-shaped mounting plate 5 perpendicular to the hinge 8 is fixedly connected to the side wall of the cabinet 1 by screws. The four sides of the "L"-shaped mounting plate 5 perpendicular to the side of the installation hinge 8 are respectively provided with waist-shaped grooves 9 for adjusting the installation position of the rotating base plate on the cabinet. The waist-shaped grooves 9 can fine-tune the installation position of the rotating base plate 3 on the side wall of the cabinet 1 up, down, left and right, and can eliminate problems such as errors caused by production.

[0029] An inverted "T"-shaped column 4 is vertically fixed at the bottom of the cabinet 1, and a locking mechanism is provided between the column 4 and the folded edge 32 installed on the side of the rotating base plate 3 away from the hinge 8, which limits the rotation of the rotating base plate 3 when it is rotated to be flush with the column 4. The locking mechanism includes a lock hook 7 fixed on the column 4 and a lock buckle 6 hinged on the rotating base plate 3 and capable of being buckled on the lock hook 7.
