Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, and in particular to a positioning device for preventing products from falling off or dropping. Background Technology

[0002] The product with the punched positioning holes is placed on the positioning pin of the forming plate (the diameter of the product's round hole is 6.0mm, and the diameter of the positioning pin is 5.5mm). The forming plate, along with the product, is placed under the heating baking plate for baking and softening. After softening, the forming plate, along with the product, is moved to the forming mold position for 3D forming. The positioning pin is fixed to the forming plate with screws. During the production process, the positioning pin may loosen or fall off from time to time.

[0003] In existing technologies, the diameter of the positioning pin is smaller than the diameter of the product's circular hole. During the baking process, the product will soften, warp, and deform. When the warping deformation is too large, the product positioning hole will detach from the positioning pin, resulting in product scrap during 3D molding and a low overall yield. Secondly, the positioning pin may loosen and fall off. When it loosens or falls off, it will cause the product to be in an incorrect position. If the positioning pin falls into the mold during the production process, it will cause the mold to be scrapped. Utility Model Content

[0004] This utility model mainly provides a positioning device to improve the yield rate of the molding process, prevent mold damage, and prevent products from falling off or detaching.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a positioning device for preventing product detachment and falling, comprising a forming disc, a positioning pin base contacting the top of the forming disc, a positioning pin lower column fixedly installed on the top of the positioning pin base, a placement hole opened on the top of the positioning pin lower column, a connecting column movably inserted into the inner surface wall of the placement hole, an upper positioning pin fixedly installed on the top of the connecting column, and a threaded column fixedly installed on the bottom of the connecting column.

[0006] Preferably, the bottom of the inner wall of the placement hole is provided with a threaded hole, and the outer wall of the threaded post is threadedly connected to the inside of the threaded hole. The upper positioning pin and the connecting post can be threadedly connected to the threaded hole through the threaded post, so that the upper positioning pin can be installed inside the lower positioning pin, which is convenient for disassembly and assembly, and thus the upper positioning pin of different sizes can be replaced as needed.

[0007] Preferably, the top of the forming disc has a positioning hole, and the bottom of the positioning pin base is fixedly installed with a positioning block, and the outer wall of the positioning block is movably inserted into the inside of the positioning hole. Through the action of the positioning hole and the positioning block, the positioning pin base can be quickly and accurately placed in the corresponding position.

[0008] Preferably, the top of the forming disc has two first circular holes, which are pre-drilled riveting holes on the forming disc.

[0009] Preferably, the top of the positioning pin base has two second circular holes, and the inner surface of the two first circular holes is connected to the interior of the two second circular holes. The two second circular holes are also pre-set riveting holes on the positioning pin base and correspond one-to-one with the two first circular holes.

[0010] Preferably, the inner surface of each of the two first circular holes is provided with a rivet, and the outer surface of each of the two rivets is provided inside the two second circular holes. The two rivets are inserted into the two first circular holes and the two second circular holes at the same time, and the rivet head is deformed by applying force with a riveting tool to form a riveting. The installation is completed in one go without loosening, which improves the yield and eliminates the risk of mold damage.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the diameter of the positioning pin is changed to a two-part structure, namely the upper positioning pin column and the lower positioning pin column, with diameters of 5.95mm and 5.0mm respectively, and the product hole diameter of 6.0mm. Through the functions of the placement hole, connecting column, threaded column and threaded hole, the upper positioning pin column can be replaced in advance according to the softening, warping and deformation of the product during the baking process. The replacement process is simple and does not require the replacement of the entire positioning pin, which improves the flexibility of this positioning device for preventing the product from falling off in the actual production process.

[0013] 2. In this utility model, the positioning pin base can be quickly and accurately placed in the corresponding position through the positioning hole and positioning block, and the two first round holes and two second round holes are aligned. Then, two rivets are inserted into the two first round holes and two second round holes at the same time, and the rivet head is deformed by applying force with a riveting tool to form a riveting. The installation is completed in one go without loosening, which improves the yield. Moreover, the positioning pin fixing method is changed from the original screw connection to the rivet structure, eliminating the risk of screw loosening and falling off during the production process and the risk of mold damage.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a positioning device for preventing products from falling off and dropping, including a forming plate 1, a positioning pin base 2 in contact with the top of the forming plate 1, a positioning pin lower column 3 fixedly installed on the top of the positioning pin base 2, a placement hole 4 opened on the top of the positioning pin lower column 3, a connecting column 5 movably inserted into the inner wall of the placement hole 4, a positioning pin upper column 6 fixedly installed on the top of the connecting column 5, and a threaded column 7 fixedly installed on the bottom of the connecting column 5.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, a threaded hole 8 is provided at the bottom of the inner wall of the placement hole 4, and the outer wall of the threaded post 7 is threadedly connected to the inside of the threaded hole 8. The upper post 6 of the positioning pin and the connecting post 5 can be threadedly connected to the inside of the threaded hole 8 through the threaded post 7, so that the upper post 6 of the positioning pin can be installed inside the lower post 3 of the positioning pin, and it is easy to disassemble and assemble, so that different sizes of upper post 6 of the positioning pin can be replaced as needed.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, the top of the forming disc 1 is provided with a positioning hole 9, and the bottom of the positioning pin base 2 is fixedly installed with a positioning block 10. The outer wall of the positioning block 10 is movably inserted into the inside of the positioning hole 9. Through the action of the positioning hole 9 and the positioning block 10, the positioning pin base 2 can be placed in the corresponding position quickly and accurately.

[0025] like Figures 1-3 As shown, the top of the forming disc 1 has two first circular holes 11, which are pre-drilled riveting holes on the forming disc 1.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, the top of the positioning pin base 2 has two second round holes 12, and the inner surface of the two first round holes 11 is connected to the interior of the two second round holes 12. The two second round holes 12 are also pre-set riveting holes on the positioning pin base 2, and correspond one-to-one with the two first round holes 11.

[0027] like Figures 1-4 As shown, rivets 13 are provided on the inner surface of the two first circular holes 11, and the outer surface of the two rivets 13 is provided inside the two second circular holes 12. The two rivets 13 are inserted into the two first circular holes 11 and the two second circular holes 12 at the same time, and the head of the rivets 13 is deformed by applying force with a riveting tool such as a rivet gun to form a riveting. The installation is completed in one go without loosening, which improves the yield and eliminates the risk of mold damage.

[0028] The usage and working principle of this device are as follows: First, the positioning pin consists of two main parts: the upper positioning pin column 6 and the lower positioning pin column 3. Since a positioning hole 9 is provided on the forming plate 1, a positioning block 10 is fixedly installed at the bottom of the positioning pin base 2, and the positioning block 10 is precisely inserted into the positioning hole 9. This allows the positioning pin base 2, the upper positioning pin column 6, and the lower positioning pin column 3 to be placed in their respective positions, aligning the two first circular holes 11 on the forming plate 1 with the two second circular holes 12 on the positioning pin base 2. Both the first and second circular holes 11 are pre-drilled riveting holes. Then, two rivets 13 are simultaneously inserted into the two first circular holes 11 and the two second circular holes 12. Using an external riveting tool, force is applied to each rivet 13 to deform its head, thus forming a riveting connection. This is achieved instead of fixing the positioning pin to the forming plate 1 using screws or other threaded connections. During the production process, there will be no loosening or detachment of the positioning pins. The riveting is installed in one go without any loosening, which greatly improves the yield rate and eliminates the risk of mold damage. Secondly, a placement hole 4 is opened at the top of the lower positioning pin column 3, and the connecting column 5 installed at the bottom of the upper positioning pin column 6 is inserted into the placement hole 4. Since a threaded column 7 is fixedly installed at the bottom of the connecting column 5, and the threaded column 7 is threadedly connected to the threaded hole 8 opened at the bottom of the inner wall of the placement hole 4, the upper positioning pin column 6 can be replaced in advance according to the softening, warping and deformation of the product during the baking process. This allows it to have a certain amount of free movement during the heating process, which can improve the yield rate of the production process. Moreover, the replacement process of the upper positioning pin column 6 is simple and does not require the replacement of the entire positioning pin, thereby improving the flexibility of this positioning device for preventing product detachment and falling in the actual production process.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
