Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a gas valve seat die. Background Art

[0002] When stamping existing gas valves, an upper mold and a lower mold are generally used to form a cavity. In the molds currently used, the cavity is generally designed as a T-shaped structure, and the three end faces of the cavity are flush with one side of the mold body to form an opening structure for mold closing processing;

[0003] Authorized patent number CN212704016U discloses a gas valve stamping die. This device mainly fixes the upper die body to the lower die body by closing the upper die body onto the lower die body and inserting the locating pin into the first through hole. This prevents the upper and lower die bodies from separating (within a small range) relative to each other, which would result in a wide gap between the upper and lower die bodies. This further ensures the relative fixation of the upper and lower die bodies. However, in actual use, the device still has the following defects:

[0004] The above patent mainly positions the mold body by inserting the positioning pin into the first through hole. However, during the use of the mold, the inner wall of the mold often needs to be cleaned, and the upper and lower mold bases are often fixedly assembled and difficult to disassemble, which increases the difficulty and inconvenience of cleaning the mold body. In addition, when the mold is closed, it is not easy to position the mold in the calibrated state, and the mold is prone to displacement deviation after closing, affecting the accuracy of the gas valve stamping process.

The adjusting screw 4 is threadedly adapted, and a card slot 13 is provided on both sides of the top of one group of splicing seats 6, and a card block 14 perpendicular to the card slot 13 is installed on both sides of the bottom of the other group of splicing seats 6. An inner sleeve 12 is provided on both sides of the interior of the lower mold base 1, and the interior of the inner sleeve 12 is respectively sleeved with an adjusting rod 5 and a spring 11 elastically connected to the adjusting rod 5. A calibration plug 10 is installed on the side where the two groups of adjusting rods 5 are close to each other, and the calibration plug 10 is inserted and positioned with the card block 14 and the card slot 13. The four groups of positioning grooves 8 are threadedly connected to the adjusting screw 4 through a threaded structure. The outer side of the four groups of adjusting screws 4 is provided with a gasket that fits with the positioning groove 8 to increase the buffering force inside the positioning groove 8;

[0021] The outer sides of the four groups of adjusting screws 4 are provided with turning handles, the outer sides of the two groups of adjusting pull rods 5 are provided with pull rings, and the outer sides of the pull rings and the turning handles are provided with anti-slip grooves. The two sides of the lower mold base 1 are provided with clamping columns, and the clamping columns and hanging rings cooperate with each other to facilitate the rotation of the adjusting screws 4 and pulling the pull rings to drive the adjusting pull rods 5 to move.

[0022] Example 1, as Figure 1-3As shown, grooves are provided at the four corners of the top of the lower die base 1, and protrusions that cooperate with the grooves are provided at the four corners of the bottom of the upper die base 7. The close mold closing between the lower die base 1 and the upper die base 7 is utilized to drive the four groups of protrusions to correspond to the groove structure that matches the preset structure, thereby accurately closing the upper die base 7 and the lower die base 1, prompting the lower die body 2 and the upper die body 15 to be completely spliced, thereby improving the accuracy of the stamping process.

[0023] Example 2, as Figure 1-3 As shown, the bottom of the two groups of card slots 13 is provided with a buffer pad, the inner wall of the two groups of card slots 13 is provided with a card hole, the interior of the two groups of card blocks 14 is provided with a positioning hole, and the two groups of adjustment rods 5 pass through the positioning holes and are fixedly matched with the card holes. The card engagement and positioning of the two groups of card slots 13 and the card blocks 14 are utilized to ensure that the lower mold body 2 and the upper mold body 15 will not be offset after precise mold closing, thereby increasing the qualified rate of gas valve seat processing.

[0024] Working principle: In the gas valve seat mold;

[0025] When the gas valve seat is processed, the upper die seat 7 can be forced to descend by closing the lower die seat 1 and the upper die seat 7, and the two sets of clamping blocks 14 can be driven to be embedded in the clamping groove 13. At this time, the mold can be automatically calibrated. At the same time, after the clamping block 14 is clamped into the clamping groove 13, the calibration plug 10 is driven by the elastic action of the spring 11 by adjusting the pull rod 5 to insert the clamping block 14 and the clamping groove 13 in the spliced state, thereby positioning the lower die seat 1 and the upper die seat 7 in the clamping state to avoid displacement and loosening between the molds, thereby performing the stamping processing of the gas valve seat. When the lower mold body 2 and the upper mold body 15 need to be disassembled and maintained, the threaded positioning of the positioning groove 8 by each two sets of adjusting screws 4 can be cancelled, so that the two sets of splicing seats 6 can be removed from the mold groove 3 opened on the surface of the lower mold base 1 and the upper mold base 7, and then the lower mold body 2 and the upper mold body 15 can be maintained and cleaned. When reassembling, the structure of the mold groove 3 is used to facilitate quick positioning, thereby increasing the operability and convenience of maintenance and cleaning of the lower mold body 2 and the upper mold body 15, and improving the functionality of the gas valve seat mold processing operation.
