Description

Technical Field

[0001] This utility model relates to the field of oil vibrating screen technology, and in particular to a built-in reinforcement structure for an injection-molded frame of an oil vibrating screen. Background Technology

[0002] The injection-molded frame serves as the support frame for the oil vibrating screen. It has a grid structure, which provides strong support and good filtration flow. Existing screens are generally relatively small in length and width. During injection molding, the built-in reinforcing structure, which serves as the inner core, adopts a steel frame support structure, including an outer square frame and internally arranged crisscrossing reinforcing steel wires, with the wires facing each other vertically, as the built-in structure of the grid frame.

[0003] As the efficiency requirements of oil vibrating screens increase and customization needs evolve, the area of ​​these screens also needs to be larger. This necessitates larger dimensions for the internal structure, sometimes requiring customization to double or even triple the size of the existing injection-molded frame. While increasing the outer frame size and reinforcing wires is relatively easy, it weakens the central support stability, leading to collapse and shrinkage in the middle of the injection-molded frame, failing to meet production specifications for flatness. Current methods involve adding steel pipes, similar to those on the sides of the outer frame, to improve central support stability. However, these large-diameter pipes, located in the center, occupy the injection molding space, causing incomplete material flow during injection molding, resulting in significant defects, poor quality, and an inability to meet the production demands of large-area injection-molded frames.

[0004] The existing large-area injection-molded frames have weak central support due to built-in reinforcement structures, resulting in poor molding quality, which needs to be addressed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an internal reinforcement structure for the injection-molded frame of an oil vibrating screen, which solves the problem that the central support of the internal reinforcement structure of the existing large-area injection-molded frame is weak and the molding quality is poor.

[0006] The technical solution adopted by this utility model is: providing an internal reinforcement structure for an injection-molded frame of an oil vibrating screen, including an outer frame, wherein several reinforcing steel wires are crisscrossed at both the upper and lower ends of the outer frame; and further including: A reinforcing plate is disposed in the middle of the outer frame. The upper and lower ends of the reinforcing plate are welded and fixed to the reinforcing steel wires on the upper and lower sides, respectively. The front and rear ends of the reinforcing plate are welded and fixed to the front and rear sides of the outer frame, respectively. The reinforcing plate has several through holes spaced apart along the front-rear direction. The through holes pass through the reinforcing plate from left to right. The thickness of the reinforcing plate in the left-right direction is less than the thickness of the side frame of the outer frame in the left-right direction.

[0007] To further optimize this technical solution, the thickness of the reinforcing sheet shall be no less than 1 mm and no more than 4 mm.

[0008] Further optimization of this technical solution also includes: The reinforcing edge is arranged along the front-to-back direction, and there are several of them. Several of the reinforcing edges are arranged on both the left and right sides of the reinforcing piece.

[0009] Further optimization of this technical solution also includes: The vertical reinforcing edges are arranged in the vertical direction, and there are several of them. Several of the vertical reinforcing edges are arranged on both the left and right sides of the reinforcing plate.

[0010] To further optimize this technical solution, the horizontal reinforcing edge and the vertical reinforcing edge are formed by punching and bending the reinforcing sheet, and the horizontal reinforcing edge and the vertical reinforcing edge are located on the side wall of the through hole.

[0011] To further optimize this technical solution, the vertical reinforcing edge and the horizontal reinforcing edge are disconnected.

[0012] To further optimize this technical solution, the reinforcing sheet is of several kinds, and the several reinforcing sheets are distributed at intervals inside the outer frame.

[0013] The beneficial effects of this utility model are as follows: 1. Reinforcing plates are installed within the outer frame to provide stable support for the internal components, improving the surface flatness of the molded frame and reducing central collapse. This design is suitable for manufacturing large-area oil vibrating screens. The reinforcing plates are thin and feature several through-holes that connect the left and right sides, facilitating the full and rapid flow of liquid during injection molding and preventing material leakage through holes, thus improving injection molding quality. The through-hole structure also reduces weight.

[0014] 2. The reinforcing plate is welded and fixed to the outer frame, and also welded to the reinforcing steel wires on the upper and lower sides, which can improve the structural strength and make it more stable. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each figure, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0018] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0020] Figure 7 The existing solution described in the background art involves adding a steel pipe to the middle of the outer frame 1. Figure 8 This is a schematic diagram of the injection-molded frame structure, with internal reinforcement structures located inside the injection-molded frame. Figure 1-6As shown, an internal reinforcement structure for an injection-molded frame of an oil vibrating screen includes an outer frame 1, with a plurality of reinforcing steel wires 101 arranged crisscrossingly at both the upper and lower ends of the outer frame 1; it also includes a reinforcing plate 2, disposed in the middle of the outer frame 1, with the upper and lower ends of the reinforcing plate 2 welded and fixed to the reinforcing steel wires 101 on the upper and lower sides respectively, and the front and rear ends of the reinforcing plate 2 welded and fixed to the front and rear sides of the outer frame 1 respectively, the reinforcing plate 2 having a plurality of spaced through holes 201 along the front and rear direction, the through holes 201 penetrating the reinforcing plate 2 from left to right, the thickness of the reinforcing plate 2 in the left and right direction being less than the thickness of the side frame of the outer frame 1 in the left and right direction.

[0021] The reinforcing sheet 2 is of several kinds, and the several reinforcing sheets 2 are distributed at intervals inside the outer frame 1.

[0022] In use, the reinforcing plate 2 is a long strip structure, welded and fixed inside the outer frame 1, located between two opposite reinforcing steel wires 101 at its upper and lower ends, and fixed to the reinforcing steel wires 101 by welding. The reinforcing plate 2 has several through holes 201 spaced apart along the front-to-back direction. The through holes 201 are open from left to right, facilitating smooth material flow during injection molding, quickly filling the outer space of the built-in reinforcing structure, and improving injection molding quality. The through holes 201 can be straight grooves, round, or square. The through holes 201 serve as channels for the injection molding material and also reduce the overall weight.

[0023] There can be one reinforcing plate 2, which is set in the middle position inside the outer frame 1. When the injection molded frame area is larger, multiple reinforcing plates 2 can be set and distributed in sequence at intervals in the middle of the outer frame 1 to improve the support stability.

[0024] Furthermore, the thickness of the reinforcing sheet 2 is not less than 1 mm and not more than 4 mm.

[0025] When in use, the reinforcing plate 2 is relatively thin, but it can provide stable support through its own steel material and the welding and fixing connection method.

[0026] Furthermore, it also includes: a horizontal reinforcing edge 3, which is arranged along the front-back direction and has several of them, with several of the horizontal reinforcing edges 3 arranged on both the left and right sides of the reinforcing piece 2.

[0027] It also includes: vertical reinforcing edges 4, which are arranged in the up-down direction and have several of them. Several vertical reinforcing edges 4 are arranged on both the left and right sides of the reinforcing piece 2.

[0028] When in use, the horizontal reinforcing edge 3 and the vertical reinforcing edge 4 can improve the structural strength of the reinforcing sheet and provide better support. This helps to maintain the flatness of the frame after injection molding. At the same time, the horizontal reinforcing edge 3 and the vertical reinforcing edge 4 protrude from the surface of the reinforcing sheet 2, which can increase the support area in the vertical direction and improve the support stability. During injection molding, the injection molding material and the reinforcing sheet 2 are more stably bonded.

[0029] Multiple horizontal reinforcing edges 3 and vertical reinforcing edges 4 can be provided. The vertical height of the vertical reinforcing edge 4 is less than the height of the reinforcing plate 2 to ensure sufficient flow space for the injection molding material. The horizontal reinforcing edges 3 and vertical reinforcing edges 4 are located entirely inside the injection molding frame.

[0030] Furthermore, the horizontal reinforcing edge 3 and the vertical reinforcing edge 4 are formed by punching and bending through the reinforcing sheet 2, and the horizontal reinforcing edge 3 and the vertical reinforcing edge 4 are located on the side wall of the through hole 201.

[0031] When in use, the horizontal reinforcing edge 3 and the vertical reinforcing edge 4 are integral with the reinforcing plate 2 and can be formed by stamping and bending. For example, when the stamping equipment punches a hole in the reinforcing plate 2 to form a through hole 201, the material inside the through hole 201 is squeezed out and bent and passes through the middle to form a flow channel. The material squeezed out and bent to one side inside the through hole 201 can form the horizontal reinforcing edge 3 and the vertical reinforcing edge 4.

[0032] Furthermore, the vertical reinforcing edge 4 and the horizontal reinforcing edge 3 are disconnected.

[0033] During use, before stamping, some material can be punched out at the through hole 201 position, so that after the final through hole 201 position is stamped and bent, the horizontal reinforcing edge 3 and the vertical reinforcing edge 4 are disconnected, which facilitates the full flow of the injection plastic.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
