Description

Technical Field

[0001] This utility model belongs to the field of hot pressing mold technology, and relates to a bottom guard plate pressing mold for forming inner hole of mold. Background Technology

[0002] With the continuous development of industrialization and the continuous improvement of production efficiency, the process of using hot press molds to produce products has gradually become popular. Hot press molds use hot pressing technology to apply high temperature and high pressure to materials, causing them to be deformed inside the mold, thereby obtaining the required shape and size.

[0003] However, existing pressing molds still have some shortcomings. Since a product usually has multiple structures, multiple pressing processes are usually required during the product manufacturing process to press different structures on the product separately. Therefore, multiple pressing molds are used or the product is processed again, which increases production costs and reduces production efficiency. Summary of the Invention

[0004] The purpose of this utility model is to address the problems existing in the current technology by proposing a bottom guard plate pressing mold for forming internal holes. The technical problem to be solved by this utility model is: how to improve the production efficiency of the pressing mold.

[0005] The objective of this utility model can be achieved through the following technical solution: A bottom guard plate pressing mold for in-mold hole forming includes an upper pressing plate and a lower pressing plate. The upper pressing plate is slidably connected to the top of the lower pressing plate. A pressing cavity is provided between the upper pressing plate and the lower pressing plate. A plurality of fixedly connected forming blocks are provided on the top of the lower pressing plate. A forming hole is provided inside the forming block. A plurality of fixedly connected driving mechanisms are provided on the top of the upper pressing plate. A plurality of vertical sliding grooves are provided inside the upper pressing plate. A pressing block is slidably connected inside the sliding groove. The driving mechanisms are respectively located directly above the sliding groove and fixedly connected to the pressing block at the bottom. The bottom of the pressing block extends into the forming hole.

[0006] In this solution, the pressure cavity is used to hold the raw material sheet that needs to be pressed into a bottom guard plate structure. After the upper and lower pressure plates close, the sheet is pressed into a structure corresponding to the pressure cavity. Then, the driving mechanism pushes the pressure block downward. When the pressure block is pressed into the forming hole, a hole-like structure is formed on the sheet. Then, the mold is opened and the pressed product is taken out. In this way, the upper and lower pressure plates are used to press the overall shape of the material first, and then the structure of the pressure block is used to press a deep hole-like structure inside the pressure cavity. There is no need to process the hole-like structure on the bottom guard plate, which improves production efficiency.

[0007] In the aforementioned die for forming the bottom guard plate with an in-mold hole, the driving mechanism consists of a hydraulic cylinder. The bottom of the hydraulic cylinder has a piston rod that reciprocates vertically, and the bottom of the piston rod has a fixed connecting assembly. The bottom of the connecting assembly is fixedly connected to the pressure block. By using a hydraulic cylinder as the driving mechanism, the reciprocating piston rod at its bottom drives the movement of the connecting assembly and the pressure block, providing sufficient power to the pressure block to form the hole structure on the bottom guard plate.

[0008] In the aforementioned die for forming the bottom guard plate, the piston rod has a horizontally positioned groove at its bottom. The connecting assembly includes a connecting rod and a guide block. The top of the connecting rod has an outwardly protruding snap-fit ​​portion, which is snap-fitted into the groove. The bottom of the connecting rod is fixedly connected to the pressure block. The snap-fit ​​portion slides horizontally into the groove from one side, fixing the top of the connecting rod to the piston rod in the vertical direction, thus enabling the connecting rod to move vertically. Adding a connecting rod structure between the pressure block and the piston rod facilitates the replacement of the pressure block and connecting rod structures.

[0009] In the aforementioned die for forming the bottom guard plate, the guide block is fixedly mounted on the bottom of the upper pressure plate. The guide block has a ring-shaped structure, and the pressure block is slidably mounted on the inner side of the guide block. The guide block serves as a guide, allowing the pressure block to be pressed vertically into the forming hole.

[0010] In the aforementioned die for forming a bottom guard plate, the forming block is located at the edge of the pressure cavity, and the top of the forming hole is connected to the pressure cavity. This allows for the formation of a hole-like structure at the edge of the bottom guard plate.

[0011] In the aforementioned die for forming the bottom guard plate, the upper and lower pressure plates have several cooling holes on their side walls, and several cooling channels are provided inside the upper and lower pressure plates. These cooling channels are connected to the cooling holes and are located on the upper and lower sides of the pressure cavity. The cooling holes are used to inject coolant, allowing the mold interior to cool down rapidly and increasing the speed of bottom guard plate shaping.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. In this solution, the upper and lower pressure plates are used to press the overall shape of the material. Then, through the structure of the pressure block, a deep hole structure is pressed inside the pressure cavity. There is no need to process the hole structure on the bottom guard plate, which improves production efficiency. Attached Figure Description

Detailed Implementation

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] Example

[0020] like Figure 1 As shown, the bottom guard plate pressing mold for forming the inner hole includes an upper pressure plate 1 and a lower pressure plate 2. The upper pressure plate 1 is slidably connected to the top of the lower pressure plate 2. The top of the upper pressure plate 1 is provided with several hydraulic cylinders 3 fixedly connected. The side walls of the upper pressure plate 1 and the lower pressure plate 2 are provided with several cooling holes 4.

[0021] like Figure 2 As shown, the upper pressure plate 1 and the lower pressure plate 2 are provided with a plurality of cooling channels 4a inside. The cooling channels 4a are connected to the cooling holes 4. A pressure cavity 5 is provided between the upper pressure plate 1 and the lower pressure plate 2. The pressure cavity 5 is used to place the bottom protective plate material to be pressed. The cooling channels 4a are located on the upper and lower sides of the pressure cavity 5.

[0022] like Figure 3 As shown, the upper pressure plate 1 has several vertical sliding grooves 1a inside, each of which is located directly below the hydraulic cylinder 3. Each sliding groove 1a contains a slidingly connected pressure block 1b. The lower pressure plate 2 has several fixedly connected forming blocks 2a at its top, each forming block 2a containing a forming hole 2a1. Each forming block 2a is located directly below the pressure block 1b, and the bottom of the pressure block 1b extends into the forming hole 2a1. The bottom of the hydraulic cylinder 3 has a piston rod 3a that reciprocates vertically, and the bottom of the piston rod 3a has a horizontally arranged slot 3a1. The top of the pressure block 1b has a fixedly connected connecting rod 6, and the top of the connecting rod 6 has an outwardly protruding snap-fit ​​part 6a. The snap-fit ​​part 6a is snap-fitted into the slot 3a1. The guide block 7 is fixedly located at the bottom of the upper pressure plate 1 and has an annular structure. The pressure block 1b is slidably connected to the inside of the guide block 7.

[0023] The working principle of this solution is as follows: Figure 1-3As shown, the pressure chamber 5 is used to place the raw material sheet to be pressed into a bottom guard plate structure. After the upper pressure plate 1 and the lower pressure plate 2 are closed, the sheet material is pressed into a structure corresponding to the pressure chamber 5. At this time, the bottom part of the pressure block 1b is pressed into the forming hole 2a1, so that a hole-like structure is initially formed on the bottom guard plate. Then, the piston rod 3a of the hydraulic cylinder 3 pushes the connecting rod 6 downward, and the connecting rod 6 drives the pressure block 1b downward to press it completely into the forming hole 2a1, forming a deeper hole-like structure on the bottom guard plate. Then the mold is opened and the pressed product is taken out. By using a two-stage pressing method, the hole-like structure is not damaged by excessive pressure, and there is no need to process the hole-like structure on the bottom guard plate again, thus improving production efficiency.
