Description

Technical Field

[0001] This application relates to the technical field of assembly molds, and particularly to a general mold base for a flywheel of a SMED quick die change hand press. Background Art

[0002] The crimp type RF radio frequency connector uses a compression connection between the two to fix the shield and the connector body together, so as to achieve the assembly of the RF radio frequency connector.

[0003] When assembling the RF radio frequency connector through the flywheel of the hand press, first install the upper mold and the lower mold at different positions on the frame and fix them in position through bolts. Then, load the radio frequency connector into the fixing fixture of the high-precision lower mold. Then, press the upper mold onto the lower mold and crimp the connector. Finally, release the upper mold and take out the product, so as to achieve the assembly of the connector.

[0004] Since the molds corresponding to different models of connectors are different, it is necessary to frequently replace the upper mold and the lower mold. At the same time, when replacing the upper mold and the lower mold, the installation accuracy of the upper mold and the lower mold will directly affect the final quality of the connector. However, the replacement speed by the method of positioning and fixing with bolts is slow and the installation accuracy is low. Therefore, there is an urgent need to design a mold base that is convenient for quickly replacing the mold and improving the mold installation accuracy. Utility Model Content

[0035] Referring to Figure 1 , a general die holder for the flywheel of a SMED quick die change hand press includes a mounting base 1 for mounting the lower die 7 and an upper die base 3 for mounting the upper die 8. The upper die base 3 is slidably arranged on the mounting base 1 through a sliding component 4. Multiple groups of positioning pins 2 for positioning the lower die 7 and the upper die 8 are arranged on the mounting base 1.

[0036] Referring to Figure 1 and Figure 2 , the mounting base 1 includes a base 11, a lower die positioning block 12 and locking bolts. The base 11 is used for fixedly mounting on the workbench. An installation groove is opened at one end of the base 11 away from the workbench. The installation groove is a through groove structure that communicates with the opposite two side ends of the base 11. The outer shell of the lower die 7 is a cylindrical structure. A locking platform 71 for facilitating the locking of the lower die 7 on the base 11 is fixedly installed at the bottom of the lower die 7. The thickness of the locking platform 71 is equal to the depth of the installation groove. The lower die 7 slides in the installation groove through the locking platform 71, so as to facilitate the adjustment of the position of the lower die 7.

[0037] Referring to Figure 1 and Figure 2 , the lower die positioning block 12 is arranged on the base 11 and positions and locks the lower die 7 on the base 11. Specifically, a locking hole 121 that is in snap-fit connection with the outside of the lower die 7 is opened on the lower die positioning block 12. The axis of the locking hole 121 coincides with the axis of the lower die 7, and the diameter of the locking hole 121 is equal to the outer diameter of the lower die 7. A guiding arc hole for facilitating the guiding of the lower die 7 into the locking hole 121 is opened at one end of the lower die positioning block 12 close to the base 11; at the same time, multiple groups of positioning holes 122 for positioning the positioning pins 2 are spaced apart on the lower die positioning block 12, so as to facilitate the positioning of the multiple groups of positioning pins 2 on the lower die positioning block 12; after the lower die positioning block 12 is installed, the locking bolt passes through the lower die positioning block 12 and is threadedly installed on the base 11, so as to lock and fix the lower die positioning block 12 on the base 11, which is convenient for the subsequent removal of the positioning pins 2 to ensure the position of the lower die positioning block 12 remains unchanged.

[0038] Referring to Figure 1 and Figure 2, a plurality of sets of positioning pins 2 are fixedly installed on the bottom plate, and the lower die 7 is placed in the installation groove, and the locking table 71 slides in the installation groove. The positioning hole 122 and the positioning pin 2 are engaged with each other, so that the lower die positioning block 12 passes through the plurality of sets of positioning pins 2 and is accurately positioned on the base 11. At the same time, the lower die 7 is guided through the guiding arc hole, and finally the lower die 7 is snap-fitted into the locking hole 121, so as to accurately position the lower die 7.

[0039] Refer to Figure 1 and Figure 2 , the structure of the upper die base 3 is symmetrical with the structure of the mounting base 1. The upper die base 3 includes a mounting block 31, an upper die positioning block 32 and fixing bolts. The upper die positioning block 32 presses and fixes the upper die 8 on the mounting block 31. The position of the upper die positioning block 32 is positioned by the end of the positioning pin 2 away from the lower die positioning block 12, so as to improve the concentricity of the lower die 7 and the upper die 8; a structure similar to the installation groove is also provided on the mounting block 31 of this embodiment, and a structure similar to the locking table 71 is also provided on the upper die 8.

[0040] Refer to Figure 1 , the sliding component 4 includes a guiding column 41 and a sliding sleeve 42. A plurality of sets of guiding columns 41 are provided. The plurality of sets of guiding columns 41 are installed on the base 11 at intervals, and the axes of the plurality of sets of guiding columns 41 are parallel to each other; the sliding sleeve 42 is fixedly installed on the mounting block 31, and the sliding sleeve 42 is slidably connected to the guiding column 41. The mounting block 31 slides on the plurality of sets of guiding columns 41 through the plurality of sets of sliding sleeves 42 and slides in the direction of approaching or departing from the lower die 7; the guiding column 41 of this embodiment is installed vertically on the base 11.

[0041] Refer to Figure 1 , a die handle 6 for driving the upper die base 3 to slide on the guiding column 41 is fixedly installed at one end of the mounting block 31 away from the upper die 8. After the die set is installed on the corresponding equipment, the die handle 6 is fixedly connected to the driving part of the equipment, so as to drive the upper die base 3 to slide along the guiding column 41 and realize the crimping of the connector.

[0042] Refer to Figure 1 , a return spring 5 is sleeved on the guiding column 41. The two ends of the return spring 5 are respectively abutted against the base 11 and the mounting block 31. After the upper die 8 and the lower die 7 crimp the connector, the return spring 5 pushes the upper die base 3 to slide away from the mounting base 1 direction and resets the upper die base 3. At the same time, it is also convenient to move the upper die base 3 away from the mounting base 1 when the upper die 8 is installed, which is convenient for the installation of the upper die base 3.

[0043] Refer to Figure 1 and Figure 2, after the lower mold 7 is accurately installed on the base 11, the upper mold 8 is installed on the mounting block 31, and then the upper mold positioning block 32 is installed on the mounting block 31. The upper mold positioning block 32 fixes the position of the upper mold 8 to ensure the installation accuracy between the upper mold positioning block 32 and the upper mold 8. Then, the upper mold base 3 slides on the guide post 41 through the sliding sleeve 42, and the upper mold positioning block 32 is installed on one end of the multi-group positioning pins 2 away from the base 11. The concentricity between the upper mold positioning block 32 and the lower mold positioning block 12 is ensured by the positioning pins 2. Then, the upper mold positioning block 32 is locked by the fixing bolts. Finally, when both the upper mold 8 and the lower mold 7 are installed and fixed, the positioning pins 2 are taken out, and finally the installation accuracy during mold replacement is improved.
