Description

Technical Field

[0001] The utility model belongs to the technical field of powder molding equipment, and in particular relates to an easily disassembled powder pressing and molding device. Background Art

[0002] In the fields of metallurgy and pharmaceuticals, mold forming technology is increasingly widely used. The process is as follows: first, different types of powders are mixed evenly with organic binders in proportion, then injected into the mold cavity, and pressed by a punch to obtain a blank with a certain geometric shape and structure.

[0003] The powder pressing equipment currently used in the industry adopts the form of an integrated template connection. The size and shape of the mold cavity cannot be adjusted, which is inconvenient to prepare different blanks for performance testing. In addition, during the stamping process, some powder will penetrate into the gap between the templates, forming waste edges at the corners of the blank, affecting the shape of the blank and packaging processes. At present, the waste edges are often cut manually, which is time-consuming and labor-intensive, and the cutting surface is uneven, which is easy to damage the integrity of the blank. A device is urgently needed to solve the above problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an easily disassembled powder pressing and molding device, comprising a workbench, a clamping assembly, a pressing assembly and a detachable mold.

[0005] Two guide rails are arranged in parallel on the workbench;

[0006] The clamping assembly includes a motor, two screws and two clamping blocks. The motor is a dual-output shaft motor and is fixed on a workbench. The two output shafts of the motor are respectively connected to a screw for transmission. The screw is arranged parallel to the guide rail and is arranged on the outside of the guide rail. The two clamping blocks are connected to the two ends of the guide rail in parallel and sliding. Each screw is threadedly connected to a through screw hole arranged on the corresponding side clamping block. When the motor is started, it can drive the two clamping blocks to move toward or away from each other.

[0007] The detachable mold includes two symmetrical modules, which are symmetrically placed in the center of a rectangle surrounded by the guide rail and the clamping block. The modules each include a bottom plate, a connecting rod and a semi-circular side wall vertically fixed on the bottom plate. The connecting rod is parallel to the guide rail and fixedly connected to the outer side of the semi-circular side wall. The other end of the connecting rod is detachably connected to the clamping block by a bolt.

[0008] The pressing assembly includes a frame-shaped bracket, a hydraulic cylinder and a pressing plate. The frame-shaped bracket is fixed on a workbench. The hydraulic cylinder is arranged directly above the removable mold, and the fixed end of the hydraulic cylinder is fixedly connected to the crossbeam of the frame-shaped bracket. The telescopic end of the hydraulic cylinder is detachably connected to the pressing plate by bolt 2, and the pressing plate matches the cavity of the removable mold.

[0009] Further, two semi-circular side walls enclose a rectangular, circular, triangular or polygonal closed pattern, and different patterns satisfy various shapes for powder pressing and forming.

[0010] Further, the thread directions of the two screws are opposite, so that when the motor rotates, it can drive the clamping blocks on both sides to move towards or away from each other.

[0011] Further, a through groove matching the guide rail is provided on the lower side of the clamping block for the clamping block to slide on the guide rail.

[0012] The present utility model further includes other devices or components that can enable the easy-to-dismantle powder pressing and forming device to be used normally, which are all conventional technical means in the art. In addition, the motors or hydraulic cylinders not defined in the present utility model all adopt conventional technical means in the art.

[0013] The working principle of the present utility model is that when the device is in use, a module of the required shape is selected and symmetrically placed on the working plate. The connecting rod is pin-connected to the clamping block, and the motor is started to drive the clamping block to move towards the middle until the module is clamped. The powder to be pressed is placed in the groove formed by the two semi-circular side walls, and the hydraulic cylinder is started to compact the powder into a shape with the pressing plate.

[0014] The beneficial effects of the present utility model are that the device has a simple structure, is easy to operate, and has a wide range of adaptability; the mold of the device is detachable, can meet various shapes for powder pressing, and multiple workbenches can be connected in series to achieve large-scale industrial applications. Using this process to prepare products has the characteristics of high precision, uniform structure, excellent mechanical properties and low production cost. BRIEF DESCRIPTION OF THE DRAWINGS
