Abstract
Description
Technical Field
[0001] This application relates to the field of mold technology, specifically to a quick-change mold structure for castings. Background Technology
[0002] Stamping and casting molds are a core process equipment in industrial production. They apply external force to metal or non-metal sheets through a specific structure, causing them to undergo plastic deformation or separation, thereby precisely forming parts that meet design requirements.
[0003] For example, patent CN222607962U discloses a die-casting sprue stamping mold. This patent connects the upper module to the upper end of the upper module through a limiting rod and the upper end of the upper module through an external driving device, so that it can be compressed.
[0004] However, traditional casting molds typically employ a single-station fixed structure, meaning that a single mold can only carry a single casting for stamping. After a single stamping operation is completed, the machine must be stopped and the finished casting must be manually removed, the workpiece to be processed must be repositioned, and the equipment must be restarted for the next round of operations. Frequent shutdowns and part changes shorten the effective operating time of the equipment and extend the production cycle of a single casting, making it difficult to meet the needs of large-scale production.
[0005] Therefore, it is necessary to provide a quick-change mold structure for castings to solve the above problems.
[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0036] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0037] like Figure 1 As shown, this application provides a quick-change mold structure for castings, including a base 1 and a stamping machine 2 fixedly disposed on the upper end of the base 1. The stamping machine 2 has a pressure plate (not shown in the figure), which is adapted to move vertically under the action of an external force. In this application, this external force can be a hydraulic cylinder.
[0038] Meanwhile, the stamping press 2 also includes a mold 21 located at the lower end of the pressure plate. The mold 21 is used to form the shape of the casting. The mold 21 includes an upper mold 22 fixedly disposed at the lower end of the pressure plate. The lower end of the upper mold 22 is fixedly provided with a protrusion for forming the surface portion of the casting.
[0039] Furthermore, the stamping machine 2 also includes a lower die 23 located on the base 1 directly below the upper die 22. The lower die 23 cooperates with the upper die 22 to facilitate the forming operation of the casting.
[0040] In order to enable rapid changeover operations for castings, such as Figures 1-4 As shown, a switching mechanism 3 is provided on the upper end of the base 1. The switching mechanism 3 includes two sets of cylinders 30 fixedly installed on the upper end of the base 1, and a mounting plate 31 is fixedly installed on the output end of the cylinders 30, so that starting the cylinders 30 can drive the mounting plate 31 to move vertically up and down.
[0041] A motor 32 is fixedly installed at the lower end of the mounting plate 31, and a rotating shaft 33 is rotatably installed on the mounting plate 31. The rotating shaft 33 extends through the mounting plate 31 to the lower end, and the output end of the motor 32 is fixedly connected to the rotating shaft 33. Thus, starting the motor 32 can drive the rotating shaft 33 to rotate on the mounting plate 31.
[0042] Meanwhile, a horizontal plate 34 is fixedly provided at the other end of the rotating shaft 33, and a first station 35 is fixedly provided at one end of the horizontal plate 34. The first station 35 is used to place the casting to be stamped and the stamped casting.
[0043] In order to facilitate subsequent switching operations, a through hole 37 is provided on the first station 35. The size of the through hole 37 is larger than the size of the lower mold 23, and the size of the through hole 37 is smaller than the size of the casting.
[0044] Furthermore, a second station 36 is provided at the other end of the horizontal plate 34. This second station 36 is set in the same way as the first station 35. So when the stamping starts, the casting is first placed in the position between the second station 36 and the first station 35 located in the through hole 37. Then, the motor 32 is started to move the first station 35 directly above the lower die 23. Then, the cylinder 30 is started to drive the horizontal plate 34 to move down. During the downward movement, the lower die 23 passes through the through hole 37 and lifts the casting. After it moves down to the appropriate position, the stamping machine 2 can start to stamp the casting. After the stamping is completed, the cylinder 30 drives the horizontal plate 34 to move up. During the upward movement, it can lift the stamped casting. The motor 32 is started to drive the first station 35 and the second station 36 to switch positions. When the stamped casting is taken out and a new casting blank is placed, the above operation can be repeated, so as to achieve the effect of quickly switching castings.
[0045] To prevent the casting from shifting during movement, such as Figure 2 and Figure 5 As shown, locking components 38 are provided at both ends of the horizontal plate 34. These locking components 38 are used to limit the position of the casting.
[0046] The locking assembly 38 includes a groove 380 formed around the through hole 37, and a limiting block 381 is slidably disposed on the groove 380. The limiting block 381 is used to limit the casting. The side of the limiting block 381 that contacts the casting is made of rubber to prevent damage to the casting.
[0047] In order to limit the casting, a locking bolt 382 is threaded on the limiting block 381, and multiple sets of positioning holes 383 are correspondingly opened on the upper end of the horizontal plate 34. The locking bolt 382 passes through the limiting block 381 and is threadedly connected to the positioning hole 383. So when the casting is placed, the position of the limiting block 381 only needs to be manually adjusted, and then the locking bolt 382 can be tightened into the positioning hole 383 to fix it, thus achieving the purpose of limiting the casting.
[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
