Description

Technical Field

[0001] This application relates to the field of tooling technology, and in particular to a molding tooling. Background Technology

[0002] Compression molding is a processing technology in which a blank is placed in a closed mold cavity and formed into a product by heating and pressurizing. It is usually achieved by compression molding fixtures. Specifically, the mold is placed on the lower platen of the compression molding fixture, and then the blank is added into the mold cavity. Then, the upper platen is pressurized by a press, causing the upper platen to move down and the protruding part to enter the mold cavity. At the same time, the mold is closed. This process completes the compression molding. However, during the process of placing the mold on the lower platen of the compression molding fixture, due to the complex structure of the compression molding fixture, when the worker directly moves and corrects the position of the mold by hand, the internal structure of the compression molding fixture will obstruct the worker's hand. This results in low convenience for the worker to directly move the position of the mold by hand. Utility Model Content

[0003] To address the aforementioned issue of low convenience in manually moving and correcting the position of the mold due to the complex structure of the molding tooling, this application provides a molding tooling.

[0004] The molding tooling provided in this application adopts the following technical solution:

[0005] A molding fixture includes a base plate, a mold, and an abutment plate. A lower pressure plate is fixedly installed on the top of the base plate by four bolts. A movable plate is movably installed on the top of the lower pressure plate. The movable plate is corresponding to the lower pressure plate by two guide members. A connector is welded to the top of the movable plate. An upper pressure plate is fixedly installed on the bottom of the movable plate by four bolts. Limiting plates one and two are respectively fixedly installed on the top two ends of the lower pressure plate by four bolts. The mold is placed in the middle of the top of the lower pressure plate. A support column is installed on one corner of the lower pressure plate by two bolts. A support member is installed on one side of the support column by four bolts. A handle and a movable member are movably hinged inside the support member. The handle and the movable member are movably connected by a hinge. The abutment plate is fixedly connected to the movable member by a connector.

[0006] Preferably, each of the two guide components consists of a threaded post, a guide sleeve, a guide post, and a nut. Circular holes are provided at both ends of the top of the movable plate. The two threaded posts movably pass through the two circular holes. The two guide sleeves are movably fitted onto the outer surfaces of the two guide posts. The two guide posts are welded to both ends of the top of the lower pressure plate. The two guide sleeves are welded to the bottom ends of the two threaded posts. The two guide sleeves abut against both ends of the bottom of the two movable plates. The two nuts are threaded onto the outer surfaces of the two threaded posts.

[0007] Preferably, the hinge consists of a hinge block and two limiting shafts, with the two limiting shafts respectively fixed through one end of the handle and one end of the movable part, and the two ends of the hinge block respectively movably sleeved on the outer surfaces of the two limiting shafts.

[0008] Preferably, the connector consists of a first connector and a second connector. The second connector is welded to the other end of the movable part, and the first connector is welded to one side of the contact plate. The first connector and the second connector are fixedly connected by two bolts.

[0009] In summary, this application includes the following beneficial technical effects: After the mold is placed on the lower pressure plate, by turning the handle, the handle drives the movable part to rotate through the hinge, and the movable part drives the abutment plate to rotate horizontally and abut against the mold through the connecting part, thereby pushing the mold to move and tightly fit against one side of the limiting plate, ensuring that the protruding part of the upper pressure plate can enter the interior of the mold for mold closing, and at the same time pressurizing the blank inside the mold; compared with the prior art, it avoids the operator directly holding the mold to move its position, and the convenience of moving the mold position is high.

[0015] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail.

[0016] Example 1:

[0017] A molding tooling, as shown in the reference Figure 1-4 The system includes a base plate 11, a mold 2, and a contact plate 34. A lower pressure plate 12 is fixedly mounted on the top of the base plate 11 by four bolts. A movable plate 13 is movably mounted on the top of the lower pressure plate 12. The movable plate 13 corresponds to the lower pressure plate 12 via two guide members 6. Each guide member 6 consists of a threaded post 61, a guide sleeve 62, a guide post 63, and a nut 64. Circular holes are opened at both ends of the top of the movable plate 13. The two threaded posts 61 movably pass through the two circular holes, and the two guide sleeves 62 movably fit on the outer surfaces of the two guide posts 63. The two guide posts 63 are welded... Two guide sleeves 62 are welded to the bottom ends of two threaded posts 61, respectively, and are attached to the top of the lower pressure plate 12. The two guide sleeves 62 abut against the bottom ends of the two movable plates 13. Two nuts 64 are threaded onto the outer surfaces of the two threaded posts 61, thereby ensuring that the movable plate 13 and the lower pressure plate 12 remain parallel and always correspond to each other. A connector 14 is welded to the top of the movable plate 13, into which the telescopic end of the hydraulic cylinder of the external press can be inserted. Then, the external bolts pass through the connector 14 and the hydraulic cylinder of the external press. The telescopic end of the cylinder can be fixed between the telescopic end of the hydraulic cylinder of the external press and the connector 14. Then, when the telescopic end of the hydraulic cylinder of the external press drives the connector 14 to rise and fall, it can drive the movable plate 13 to rise and fall. The external press is a compact and versatile press with wide applications and high production efficiency. The press can be widely used in processes such as cutting, punching, blanking, bending, riveting, and forming. It uses its own hydraulic cylinder to apply strong pressure to the metal blank to cause plastic deformation and fracture of the metal to process it into parts. The bottom end of the movable plate 13 is connected to the external press. The upper pressure plate 15 is fixedly installed by four bolts 2. The two ends of the top of the lower pressure plate 12 are respectively fixedly installed by four bolts 3. The first limit plate 16 and the second limit plate 17 cooperate to initially limit the mold 2. The mold 2 is placed in the middle of the top of the lower pressure plate 12. When the extension end of the hydraulic cylinder of the external press drives the connector 14 to descend, the connector 14 drives the movable plate 13 to descend, and the connector 14 drives the upper pressure plate 15 to descend, so that the protruding part of the upper pressure plate 15 enters the interior of the mold 2 to close the mold, and at the same time pressurizes the blank inside the mold 2.

[0018] Reference Figure 1-4A support column 31 is installed on one corner of the lower pressure plate 12 by two bolts. A support member 32 is installed on one side of the support column 31 by four bolts. A handle 33 and a movable member 35 are hinged inside the support member 32. The handle 33 and the movable member 35 are movably connected by a hinge member 4. The hinge member 4 consists of a hinge block 41 and two limiting shafts 42. The two limiting shafts 42 are fixedly inserted through one end of the handle 33 and one end of the movable member 35, respectively. The two ends of the hinge block 41 are movably sleeved on the outer surface of the two limiting shafts 42. The contact plate 34 is fixedly connected to the movable member 35 by a connector 5. The connector 5 consists of a first connector block 51 and a second connector block 52. The components consist of a second connecting block 52 welded to the other end of the movable part 35, and a first connecting block 51 welded to one side of the abutment plate 34. The first connecting block 51 and the second connecting block 52 are fixedly connected by two bolts. During the process of placing the mold 2 on the lower pressure plate 12, it should be noted that by turning the handle 33, the handle 33 drives the movable part 35 to rotate through the hinge 4. The movable part 35 drives the abutment plate 34 to rotate horizontally through the connecting part 5 and abut against the mold 2, thereby pushing the mold 2 to move and fit tightly against one side of the limit plate 17, ensuring that the protruding part of the upper pressure plate 15 can enter the interior of the mold 2 for mold closing, and at the same time pressurizing the blank inside the mold 2.
