AI Technical Summary
[0003]现有技术中,为避免在模具成型腔室寿命到期后需要对模具进行整体更换,通常会单独设置用于形成成型腔室的模腔板,以便在模腔板无法使用后进行单独更换,如授权公告号CN220992552U的实用新型专利所公开的方案,但是现有的模腔板大多是直接利用螺栓固定在上模具底部或下模具顶部,不仅在更换时需要将用于固定的螺栓完全取下,易导致螺栓丢失,同时螺栓端部位于成型腔室内,对于工件的正常成型存在较大影响
[0015]本实用新型通过设置有可拆成型组件,以便于上模具带动成型块持续下移时,成型块对位于下模具顶部的原料进行冲压,进而使原料发生形变并进入到模腔板内侧,进而在成型块与模腔板的配合作用下成型,当需要对成型块与模腔板进行更换时,将两个安装螺栓由两个连接螺孔内侧旋出,此时成型块顶部的连接螺孔可以直接由上方连接槽内侧脱出,模腔板则可以向上提拉,进而带动模腔板由容纳槽内侧,模腔板底部的连接块则由下方连接槽内侧脱出,此时两个安装螺栓任意位于两个安装螺孔内侧前半段,相较于现有技术,本实用新型在更换成型块与模腔板时无需将安装螺栓完全取下,进而避免出现安装螺栓取下后丢失的情况,同时针对成型块与模腔板进行安装的安装螺栓不会对成型块与模腔板的成型功能造成影响,保证了成型质量。

Description
Technical Field
[0001] This utility model relates to the field of mold technology, and in particular to a PVD coating mold that is easy to use. Background Technology
[0002] Molds can mass-produce workpieces while maintaining high efficiency and precision. PVD refers to physical vapor deposition, which can be used to coat the inner surface of the mold forming chamber, thereby improving the hardness of the mold forming chamber, improving wear resistance and service life.
[0003] In the prior art, in order to avoid the need to replace the entire mold after the mold forming chamber reaches the end of its lifespan, a mold cavity plate is usually set separately to form the forming chamber so that it can be replaced separately when the mold cavity plate is no longer usable, such as the solution disclosed in the utility model patent with authorization announcement number CN220992552U. However, most existing mold cavity plates are directly fixed to the bottom of the upper mold or the top of the lower mold with bolts. Not only do they need to be completely removed when replacing, which can easily lead to the loss of bolts, but the bolt ends are located in the forming chamber, which has a significant impact on the normal forming of the workpiece.
[0004] Therefore, it is necessary to invent an easy-to-use PVD coating mold to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a user-friendly PVD coating mold that eliminates the need to completely remove the mounting bolts when replacing the molding block and the mold cavity plate, thus avoiding the loss of the mounting bolts. Furthermore, the mounting bolts used to install the molding block and the mold cavity plate do not affect their molding function, ensuring molding quality. This addresses the problem mentioned in the background art where existing mold cavity plates are mostly directly fixed to the bottom of the upper mold or the top of the lower mold with bolts. This not only requires the complete removal of the fixing bolts during replacement, easily leading to bolt loss, but also, the bolt ends being located within the molding cavity, significantly impacting the normal molding of the workpiece.
[0006] According to one aspect of this disclosure, the following technical solution is provided: a user-friendly PVD coating mold, comprising:
[0007] Upper and lower mold assemblies, which provide an installation base for the demolding lifting assembly and the detachable molding assembly;
[0008] A demolding lifting assembly, used to lift the molded workpiece; and
[0009] A detachable molding assembly includes molding blocks and a mold cavity plate distributed vertically. Both the molding blocks and the mold cavity plate have a PVD coating. The mold cavity plate is adapted to a receiving groove and has a clearance hole at its bottom adapted to a lifting rod. Connecting blocks adapted to adjacent connecting grooves are fixedly installed on the top of the molding blocks and the bottom of the mold cavity plate. Connecting screw holes are opened on the front of the connecting blocks. The detachable molding assembly also includes two mounting screw holes opened on the front of the lower mold and the front of the upper mold. Each mounting screw hole is collinear with the adjacent connecting screw hole, and a mounting bolt is screwed into the inner side of each mounting screw hole and the adjacent connecting screw hole.
[0010] According to at least one embodiment of the present disclosure, an easy-to-use PVD coating mold is provided, wherein the upper and lower mold assembly includes a lower mold, and guide posts are fixedly provided at the four corners of the top of the lower mold. An upper mold is slidably sleeved on the outer side of the four guide posts along the vertical direction via linear bearings.
[0011] According to at least one embodiment of the present disclosure, an easy-to-use PVD coating mold is provided with a receiving groove at the top of the lower mold, and a connecting groove is provided at the bottom of the upper mold and the bottom of the inner cavity of the receiving groove.
[0012] According to at least one embodiment of the present disclosure, the easy-to-use PVD coating mold includes a demolding lifting assembly comprising a U-shaped support base plate fixedly disposed at the bottom of the lower mold, wherein the bottom front of the U-shaped support base plate is provided with an clearance groove.
[0013] According to at least one embodiment of the present disclosure, a user-friendly PVD coating mold is provided in which a counterweight plate is slidably attached to the inner side of the U-shaped support base plate in the vertical direction, and a lifting rod is fixedly provided on both sides of the top of the counterweight plate. Any one of the lifting rods slides through the lower mold in the vertical direction and extends to the inner side of the receiving groove and is flush with the bottom surface of the inner cavity of the mold cavity plate.
[0014] The technical effects and advantages of this utility model are as follows:
[0015] This invention features a detachable forming component. When the upper mold moves the forming block downwards, the forming block presses the raw material at the top of the lower mold, causing deformation and guiding the material into the mold cavity plate. The material is then formed through the interaction of the forming block and the mold cavity plate. When the forming block and mold cavity plate need to be replaced, the two mounting bolts are unscrewed from the two connecting screw holes. The connecting screw hole at the top of the forming block can then be directly dislodged from the upper connecting groove, and the mold cavity plate can be pulled upwards, moving it from the receiving groove. The connecting block at the bottom of the mold cavity plate dislodges from the lower connecting groove. At this point, the two mounting bolts are arbitrarily positioned in the front half of the two mounting screw holes. Compared to existing technologies, this invention eliminates the need to completely remove the mounting bolts when replacing the forming block and mold cavity plate, preventing loss. Furthermore, the mounting bolts used to install the forming block and mold cavity plate do not affect their forming function, ensuring molding quality. Attached Figure Description

[0026] Figure 2 This is a partial structural diagram of an easy-to-use PVD coating mold according to one embodiment of the present disclosure, comprising an upper and lower mold assembly 1, a demolding and lifting assembly 2, and a detachable molding assembly 3.
[0027] Figure 3 This is a partial structural diagram of a detachable molding component 3 of an easy-to-use PVD coating mold according to one embodiment of the present disclosure.
[0028] like Figures 1-3 As shown, the easy-to-use PVD coating mold disclosed herein may include components such as: upper and lower mold assembly 1, demolding and lifting assembly 2, and detachable molding assembly 3.
[0029] like Figure 2 As shown in this disclosure, the upper and lower mold assembly 1 includes a lower mold 11, which serves as a fixed base and is made of gray cast iron. It has good shock absorption and is suitable for withstanding stamping impact. Guide posts 12 are fixedly installed at the four corners of the top of the lower mold 11. The guide posts 12 are made of high-hardness alloy steel and are polished to Ra≤0.8μm after heat treatment. An upper mold 13 is slidably sleeved on the outer side of the four guide posts 12 along the vertical direction through linear bearings. The upper mold 13 is made of the same gray cast iron as the lower mold 11. A connecting flange for connecting to the output shaft of an external hydraulic cylinder is reserved at the top. A receiving groove 14 is opened at the top of the lower mold 11, and connecting grooves 15 are opened at the bottom of the upper mold 13 and the bottom of the inner cavity of the receiving groove 14.
[0030] This facilitates the connection between the top of the upper mold 13 and the output shaft of the external hydraulic cylinder. Subsequently, when the upper mold 13 moves downward under the action of the hydraulic cylinder output shaft, the upper mold 13 drives the forming block 31 to move downward continuously. At this time, the forming block 31 presses the raw material located at the top of the lower mold 11, thereby deforming the raw material and entering the inner side of the mold cavity plate 32, and then forming under the cooperation of the forming block 31 and the mold cavity plate 32.
[0031] like Figure 2 As shown, in a preferred embodiment, the demolding lifting assembly 2 includes a U-shaped support base plate 21 fixedly disposed at the bottom of the lower mold 11. An avoidance groove 22 is provided at the bottom front of the U-shaped support base plate 21. A counterweight plate 23 is slidably attached to the inner side of the U-shaped support base plate 21 in the vertical direction. Lifting rods 24 are fixedly disposed on both sides of the top of the counterweight plate 23. Any one of the lifting rods 24 slides through the lower mold 11 in the vertical direction and extends to the inner side of the receiving groove 14 and is flush with the bottom surface of the inner cavity of the mold cavity plate 32.
[0032] This facilitates the connection between the bottom of the counterweight plate 23 and the output shaft of the external hydraulic cylinder. At this time, the output shaft of the hydraulic cylinder is located inside the clearance groove 22. After the workpiece is formed and the upper mold 13 moves up and resets, the counterweight plate 23 moves up due to the drive of the hydraulic cylinder. When the counterweight plate 23 moves up, it pushes the workpiece formed inside the mold cavity plate 32 through the two lifting rods 24, thereby causing the workpiece to be pushed out from inside the mold cavity plate 32, making it convenient to remove the workpiece.
[0033] like Figure 2 and Figure 3 As shown in this disclosure, the detachable molding component 3 includes a molding block 31 and a mold cavity plate 32 distributed in a vertical direction. The bottom of the molding block 31 is a stamping surface, designed according to the shape of the workpiece, such as a flat surface, curved surface, or irregular structure. Both the surfaces of the molding block 31 and the mold cavity plate 32 are provided with a PVD coating. The mold cavity plate 32 is located in the receiving groove 14, and the inner cavity shape matches the workpiece. Two clearance holes are opened at the bottom to match the lifting rod 24 and avoid interference during lifting. The top of the molding block 31 and the bottom of the mold cavity plate 32 are both fixedly provided with connecting blocks 33 that match the adjacent connecting groove 15. The front of the connecting block 33 is provided with a connecting screw hole 34. The detachable molding component 3 also includes two mounting screw holes 35 opened on the front of the lower mold 11 and the front of the upper mold 13. Any mounting screw hole 35 is collinear with the adjacent connecting screw hole 34. The inner side of any mounting screw hole 35 and the adjacent connecting screw hole 34 are screwed with mounting bolts 36.
[0034] Therefore, when it is necessary to replace the molding block 31 and the mold cavity plate 32, the two mounting bolts 36 can be unscrewed from the inside of the two connecting screw holes 34. At this time, the connecting screw holes 34 at the top of the molding block 31 can be directly dislodged from the inside of the upper connecting groove 15, and the mold cavity plate 32 can be pulled upward, thereby driving the mold cavity plate 32 out of the inside of the receiving groove 14. The connecting block 33 at the bottom of the mold cavity plate 32 is dislodged from the inside of the lower connecting groove 15. At this time, the two mounting bolts 36 are arbitrarily located in the front half of the inside of the two mounting screw holes 35. Compared with the prior art, when replacing the molding block 31 and the mold cavity plate 32, it is not necessary to completely remove the mounting bolts 36, thereby avoiding the situation of losing the mounting bolts 36 after removal. At the same time, the mounting bolts 36 used to install the molding block 31 and the mold cavity plate 32 will not affect the molding function of the molding block 31 and the mold cavity plate 32, thus ensuring the molding quality.
[0035] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.
[0036] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
