Description

[Technical field]

[0001] The utility model relates to a material distribution tool for pressing low-density tungsten alloy. [Background technology]

[0002] When low-density tungsten alloy ring products are pressed, different sizes of tungsten alloy ring products need to use different scraper plates to scrape the wax alloy particles poured into the mold cavity before pressing, so as to ensure the uniformity of density and size consistency of the pressed blanks. Due to the different specifications of ring products and different mold cavity sizes, different scraper plates are needed to scrape different molds. For this purpose, many scraper plates need to be made, which not only increases the tool manufacturing cost, but also is not conducive to the management and maintenance of the tool.

[0003] Therefore, it is necessary to make further improvements. [Utility Model Content]

[0004] The purpose of the utility model is to overcome the above problems. We provide a material distribution tool for pressing low-density tungsten alloy, which can meet the material distribution requirements when pressing various ring products.

[0005] To achieve the above purpose, we provide a feeding tool for pressing low-density tungsten alloy, which includes a mold, a scraper plate and a scraper part. The mold has an annular mold cavity. The scraper plate is arranged on the mold and can rotate horizontally relative to the mold. The scraper plate has a plurality of scraper arms evenly distributed axially, and each scraper arm is provided with a plurality of mounting holes. The distance from the center of each mounting hole to the center of the mold cavity is inconsistent. The scraper part is arranged in the mold cavity and is connected and fixed to one of the above-mentioned plurality of mounting holes.

[0006] In one or more embodiments, the mounting hole is a threaded hole, and the scraper portion has a stud connected to the threaded hole.

[0007] In one or more embodiments, the scraper plate has a positioning cone, the root of the scraper arm is connected to the positioning cone, the end of the scraper arm extends radially outward, the center position of the mold has a positioning cavity that cooperates with the positioning cone, and the positioning cone can rotate relative to the positioning cavity.

[0008] In one or more embodiments, the centers of all mounting holes on each scraper arm and the center of the mold cavity are in a straight line.

[0009] In one or more embodiments, the scraper arm is provided with a scale mark on one side of each mounting hole, and the scale mark is the distance from the center of the mounting hole to the center of the mold cavity.

[0010] Compared with the background technology, the utility model has the following technical effects: the material distribution tool concentrates the scraping material sizes required for pressing different ring-type products on a scraper plate, and is equipped with a corresponding, detachable scraper rod to meet the material distribution requirements when pressing a variety of ring-type products, thereby improving the versatility and standardization of the tool and reducing production costs.

[0013] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0014] Please see Figure 1-2 The present application provides a material distribution tool for pressing low-density tungsten alloy, which includes a mold 1, a scraper plate 2 and a scraper part 3. The mold 1 has an annular mold cavity 4. The scraper plate is arranged on the mold and can rotate horizontally relative to the mold. The scraper plate 2 has a plurality of axially evenly distributed scraper arms 5, each of which is provided with a plurality of mounting holes 6. The distance from the center of each mounting hole to the center of the mold cavity 4 is inconsistent. The scraper part 3 is arranged in the mold cavity and is connected and fixed to one of the plurality of mounting holes 6. By transferring the scraper plate to different molds 1 for use, and finding the mounting hole of the mold cavity on the scraper arm corresponding to the mold, the scraper part can be installed and used, so that the effect of a single scraper plate matching multiple molds can be achieved.

[0015] The mounting hole 6 is a threaded hole, and the scraper part has a stud 31 connected to the threaded hole. The scraper part is mounted in a threaded manner, which has the advantages of easy installation and removal, so that the user can change the position of the scraper part according to the size of the mold cavity of different molds.

[0016] The scraper plate 2 has a positioning cone 7, the root of the scraper arm 5 is connected to the positioning cone, the end of the scraper arm extends radially outward, and the center position of the mold 1 has a positioning cavity 8 that cooperates with the positioning cone. The positioning cone can rotate relative to the positioning cavity. With the cooperation of the cone and the positioning cavity, the user can easily rotate the scraper plate to make the scraper part rotate around the mold cavity and scrape it flat.

[0017] The centers of all the mounting holes 6 on each scraper arm 5 and the center of the mold cavity 4 are all on a straight line, so as to improve the uniformity of the mounting holes and avoid confusion in the positions of the mounting holes.

[0018] The scraper arm 5 is provided with a scale mark 9 on one side of each mounting hole 6, and the scale mark is the distance from the center of the mounting hole to the center of the mold cavity. The user can check the mold cavity size on the mold and then quickly find the corresponding mounting hole from the scale mark to install the scraper part.

[0019] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
