[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1-4 This is the first embodiment of the present invention, which provides a molding die with a cushioning function, including...

[0027] The lower mold base 1 has symmetrically distributed vertical plates 2 installed at its top, which realizes the splicing of the vertical plates 2 and the lower mold base 1. The top plates 3 are installed on the top of the two vertical plates 2, which increases the support for the top plates 3 through the vertical plates 2.

[0028] The lifting mechanism includes a hydraulic cylinder 31 installed on the top of the top plate 3, which realizes the addition of the hydraulic cylinder 31. The output end of the hydraulic cylinder 31 passes through the top plate 3 and is connected to the upper mold base 4. When the hydraulic cylinder 31 is started, it can drive the upper mold base 4 to lift.

[0029] The forming mechanism includes an extrusion module B11 installed on the top of the lower die base 1, which realizes the addition of the extrusion module B11, and the top of the extrusion module B11 is provided with a forming cavity 110, which realizes the opening of the forming cavity 110. An extrusion module A41 is set at the bottom of the upper die base 4, and a forming pressure block 410 is set at the bottom of the extrusion module A41. The material is placed in the forming cavity 110, and the hydraulic cylinder 31 is pressurized by the hydraulic pump, so that the hydraulic shaft pushes the upper die base 4 downward, so that the forming pressure block 410 at the bottom of the extrusion module A41 is squeezed into the forming cavity 110. The material can be squeezed and shaped in the forming cavity 110 through extrusion.

[0030] The buffer mechanism includes multiple fixed columns 5 installed on the top of the lower die base 1, which realizes the addition of fixed columns 5; a slide block 7 slidably disposed inside the fixed columns 5, which can slide inside the fixed columns 5 to increase the convenience of use; a movable column 6 disposed on the top of the slide block 7, which realizes the addition of movable column 6; and a first spring 51 disposed at the bottom inside the fixed columns 5, with the top of the first spring 51 connected to the slide block 7. When the upper die base 4 descends and presses on the movable column 6, the movable column 6 drives the slide block 7 to compress the first spring 51, thereby increasing the buffering performance, reducing the impact and vibration of the die during the extrusion molding process, and improving the precision and quality of the molded product.

[0031] In this embodiment, preferably, an insert 61 is also provided at the bottom of the movable column 6, which realizes the addition of the insert 61. A slot 71 is opened on the top of the slide block 7 for the insert 61 to be inserted, so that the insert 61 is inserted into the slot 71.

[0032] In this embodiment, preferably, the inner side of the slot 71 is provided with a stop 710 that can abut against the insert 61, thus realizing the addition of the stop 710. The inner wall of the fixing column 5 is provided with a second sliding groove 52 for the slide block 7 to slide. The smoothness of the movement is increased by sliding the slide block 7 and the second sliding groove 52.

[0033] In this embodiment, preferably, a first slide groove 21 is opened on the side surface of the vertical plate 2, and an extension ear 42 is set on the side surface of the upper mold base 4 and can slide in the first slide groove 21. The sliding of the extension ear 42 in the first slide groove 21 increases the smoothness of the lifting and lowering of the upper mold base 4.

[0034] In this embodiment, preferably, a fixed seat 8 is installed at the top of the first slide groove 21, which realizes the addition of the fixed seat 8. The fixed seat 8 is provided with a buffer component, which includes a groove 81 opened inside the fixed seat 8, realizing the opening of the groove 81, a second spring 810 provided at the bottom of the groove 81, realizing the addition of the second spring 810, and a movable plate 8101 provided at one end of the second spring 810. The upper mold seat 4 lifts and moves the extension ear 42 to slide in the first slide groove 21. When the extension ear 42 abuts against the movable plate 8101, the movable plate 8101 compresses the second spring 810, increasing the buffering performance.

[0035] Example 2

[0036] Please see Figures 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment, but differs in that:

[0037] It also includes a first fastening piece that fixes the lower mold base 1 and the vertical plate 2, which helps to achieve a stable connection between the lower mold base 1 and the vertical plate 2, and a second fastening piece that fixes the top plate 3 and the vertical plate 2, which helps to achieve a stable connection between the top plate 3 and the vertical plate 2.

[0038] It should be noted that the specific structure and working principle of the hydraulic cylinder 31, extrusion module B11, extrusion module A41, forming block 410, and forming cavity 110 in this application have been disclosed in an extrusion molding die with buffer protection in patent publication number CN222058723U.

[0039] The working principle and usage process of this utility model are as follows: When in use, the material is placed in the forming cavity 110, and the hydraulic cylinder 31 is pressurized by the hydraulic pump, so that the hydraulic shaft pushes the upper mold base 4 downward, so that the forming block 410 at the bottom of the extrusion module A41 is extruded into the forming cavity 110. Through extrusion, the material can be extruded and shaped in the forming cavity 110.

[0040] Although embodiments of the present invention have been shown and described in detail above, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
