It is circumferentially evenly arranged on the outside of guide post for several and osculating element.
While multiple osculating elements can guarantee stable to lower mold body guiding, the contact area with lower mold body is reduced to the greatest extent.
In above-mentioned thermoforming stamping die in the bindiny mechanism of lower mold body and guide post, stretched out on the outside of the contact portion
Guide post.
It can guarantee and be steadily contacted on the outside of contact portion on the inside of lower mold body in this way.
In above-mentioned thermoforming stamping die in the bindiny mechanism of lower mold body and guide post, contact portion end has
The guide part of smooth transition.
In above-mentioned thermoforming stamping die in the bindiny mechanism of lower mold body and guide post, the guide part is contact portion
The fillet of end.
In above-mentioned thermoforming stamping die in the bindiny mechanism of lower mold body and guide post, the guide part is contact portion
The chamfering of end.
Card resistance occurs between being avoided that on the inside of contact portion and lower mold body under the action of guide part.
Compared with prior art, in this thermoforming stamping die the bindiny mechanism of lower mold body and guide post due to contact portion it is steady
Surely it is resisted against on the inside of lower mold body, can be reduced the contact area between lower mold body in this way, while lower mold body can be stablized again and support,
Therefore, below physical efficiency relative to the smooth movement of guide post, stability is relatively high.
Meanwhile contact portion has the trend being resisted against on the inside of lower mold body always under the effect of the elastic force of spring, therefore, into one
Step improves its stability, and structure is not also compact, has very high practical value.
