DETAILED DESCRIPTION

[0019] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0020] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0021] Example:

[0022] A metal sheet feeding fixture, see attached Figure 1 As shown, it comprises a pressing plate 1 and a bottom plate 2 arranged below the pressing plate 1, a spring support 3 is arranged between the pressing plate 1 and the bottom plate 2, and a mounting block 4 is arranged on the bottom plate 2. Figure 2 As shown, the mounting block 4 is provided with a feeding hole 5, which is a vertical through-hole structure, and the metal sheet 6 can be loosely fitted at the bottom of the feeding hole 5. The pressing plate 1 is provided with an ejector pin 7, which vertically penetrates into the feeding hole 5 along the top of the feeding hole 5. Specifically, the attached Figure 3 and attached Figure 4 As shown, the pressing plate 1 is provided with a mounting groove 11, and the top of the ejector pin 7 is clamped in the mounting groove 11. Figure 1 As shown, the surface of the pressing plate 1 is provided with a fixing plate 12 to prevent the ejector pin 7 from moving upward along the mounting groove 11. The lower surface of the pressing plate 1 is provided with a guide slide bar 8, the lower surface of the bottom plate 2 is provided with a guide bearing 9 matched with the guide slide bar 8, and the upper surface of the bottom plate 2 is fixedly provided with a limit column 10 sleeved on the guide slide bar 8.

[0023] In the specific use process of the utility model, the metal sheet 6 is manually inserted into the bottom of the feeding hole 5. The size of the feeding hole 5 is slightly smaller than the size of the metal sheet 6. A tight gap fit is formed between the metal sheet 6 and the feeding hole 5 to prevent the metal sheet 6 from falling off from the feeding hole 5. Figure 1 As shown, in order to facilitate the picking up and placing of the entire loading fixture, a handle 13 is fixedly installed on the upper surface of the pressure plate 1. Secondly, more preferably, a horizontally arranged placement plane 14 is provided on the handle 13. During the loading process, the entire fixture can be turned upside down on the workbench through the placement plane 14, which can not only prevent the fixture from tipping over, but also make it more convenient to load the metal sheet 6.

[0024] After the metal material is loaded on the fixture, when the mold is opened, refer to the attached Figure 5 As shown, transfer the fixture to the mold by the handle and continue to refer to the attached Figure 1 As shown, positioning posts 15 are respectively provided on the front and rear sides of the bottom plate 2, and positioning holes corresponding to the positioning posts 15 are provided on the mold. The loading fixture is positioned by inserting the positioning posts 15 into the positioning holes on the mold. More preferably, in order to facilitate the insertion of the positioning posts into the positioning holes, a positioning cone head 16 is provided at the bottom of the positioning posts 15. When the positioning posts 15 are inserted into the positioning holes, the positioning cone head 16 can play a guiding role. Figure 1 and attached Figure 5 As shown, support plates 17 are fixedly installed on the left and right sides of the bottom plate 2, and support columns 18 are fixedly installed on the support plates 17. The support columns 18 can support the entire loading fixture to prevent the loading fixture from tipping over.

[0025] See attached Figure 6 As shown, when the loading fixture is placed, the metal sheet 6 is aligned with the position of the mold cavity. At this time, the pressing plate 1 is pressed downward, and the pressing plate 1 moves downward along the guide bearing 9 along the guide slide bar 8. The pressing plate 1 squeezes the spring pillar 3 during the downward movement, and the ejector 7 pushes the metal sheet 6 installed at the bottom of the mounting block 4 into the mold cavity. When the pressing plate 1 moves to the top surface of the limiting column 10, the pressing plate 1 stops moving under the obstruction of the limiting column 10, and the metal sheet 6 is in place in the mold cavity under the action of the ejector 7, completing the loading of the metal sheet 6. After the loading is completed, release the pressing plate 1, and the pressing plate 1 is reset under the action of the spring pillar 3. At this time, the entire fixture can be removed from the mold for the next loading operation.

[0026] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
