Description

Technical Field

[0001] This utility model relates to the field of hardware accessories manufacturing technology, and in particular to an extrusion molding device for manufacturing hardware accessories. Background Technology

[0002] Hardware accessories refer to machine parts or components made of hardware, as well as some small hardware products. They can be used alone or as auxiliary tools, such as hardware tools, hardware parts, daily hardware, building hardware, and security products. Most small hardware products are not final consumer goods, but rather supporting products, semi-finished products, and tools used in the production process of industrial manufacturing. When processing hardware accessories, extrusion molding equipment is required to extrude and mold the blanks.

[0003] Most existing extrusion molding devices require operators to place the metal blanks on the lower die for loading, then extrude and mold them before removing the blanks. This loading and unloading method poses safety hazards. Furthermore, after the blanks are extruded, they fit tightly against the mold cavity of the lower die, making it inconvenient for operators to unload them and increasing their workload. Therefore, these devices are not suitable for extrusion molding and cannot meet customer needs.

[0004] Therefore, those skilled in the art have provided an extrusion molding apparatus for manufacturing hardware accessories to solve the problems mentioned in the background art. Utility Model Content

[0035] In this embodiment: By setting up a drive box 1, an L-shaped plate 2, a first electric cylinder 3, a lifting plate 4, an upper mold 5, a movable plate 6, a lower mold 7, and a guide assembly 14, this utility model can easily extrude and form hardware parts blanks.

At the same time, it can effectively reduce the labor intensity of workers and avoid potential safety hazards.

[0036] Example 2:

[0037] Reference Figure 1 , Figure 2 and Figure 4The guide assembly 14 includes a guide rod 141. The bottom of the guide rod 141 is fixedly connected to the connection of the lifting plate 4. Slide cylinders 142 are embedded on both the left and right sides of the top of the L-shaped plate 2. The inner surface of the slide cylinder 142 is slidably connected to the outer surface of the guide rod 141. The top of the guide rod 141 extends above the slide cylinder 142 and is fixedly connected to a limiting plate 15. There are two limiting plates 15.

[0038] In this embodiment: By setting guide rod 141 and slide cylinder 142, the present invention can conveniently guide and support the lifting plate 4.

[0039] The implementation principle of this utility model is as follows: In use, the operator connects the device to mains power. Then, the operator places the blank material on the lower mold 7 on the top left side of the movable plate 6. Next, the operator activates the external controller of the second electric cylinder 12, causing the extension end of the second electric cylinder 12 to move the drive plate 13 to the right. This causes the drive plate 13 to move the movable plate 6 to slide to the right on the outer surface of the slide rail 17. This allows the movable plate 6 to move the left lower mold 7 and the blank material below the upper mold 5, thus loading the blank material. Simultaneously, the lower mold 7 on the right side of the movable plate 6 moves out of the lower mold 5. Then, the operator places the blank material in the right lower mold 7. Above, the material is fed into the lower mold 7 on the right side. Then, the operator starts the external controller of the first electric cylinder 3, which causes the extension end of the first electric cylinder 3 to move the lifting plate 4 downward. At the same time, the lifting plate 4 moves the upper mold 5 downward to extrude the blank. Thus, the upper mold 5 and the lower mold 7 work together to extrude and form the blank. When the blank is extruded and formed, the blank is extruded and moves downward, which causes the blank to move the convex push plate 11 downward. The convex push plate 11 moves the slide plate 9 downward on the inner surface of the slide 16 to extrude the spring 10, which causes the convex push plate 11 to move downward into the inner cavity of the positioning cylinder 8, thereby realizing the extrusion and forming of the blank.

[0040] When the blank is extruded and molded, the operator activates the external controller of the first electric cylinder 3 again, causing the telescopic end of the first electric cylinder 3 to retract, which moves the lifting plate 4 upward. This causes the lifting plate 4 to move the upper mold 5 upward away from the lower mold 7. At the same time, the spring 10 pushes the slide plate 9 upward under the reaction force, causing the slide plate 9 to move the convex push plate 11 upward. This causes the convex push plate 11 to move upward and push the molded blank, so that the top of the molded blank extends above the lower mold 7. Then, the operator activates the external controller of the second electric cylinder 12 again, causing the telescopic end of the second electric cylinder 12 to retract, which moves the drive plate 13 to the left. This causes the drive plate 13 to move the movable plate 6 to slide to the left on the outer surface of the slide rail 17, thus causing the movable plate... The device 6 moves the lower mold 7 on the left side and the forming blank out of the lower mold 5 and back to the initial position, making it convenient for the operator to unload the forming blank and load the blank to be formed. At the same time, the lower mold 7 on the right side of the movable plate 6 moves the blank to the right and below the upper mold 5, thereby loading the blank. Then, the operator restarts the external controller of the first electric cylinder 3, so that the upper mold 5 and the lower mold 7 work together to extrude and form the blank. The principle is the same as above, so it will not be elaborated on here. This process is repeated to achieve the extrusion forming of hardware parts. This device is simple to operate and convenient for loading, unloading and extruding, thus meeting the needs of customers. At the same time, it effectively reduces the labor intensity of the operators and avoids potential safety hazards.

[0041] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
