Description
Technical field
The utility model is specifically related to a kind of hot forming tool detent mechanism, belongs to automobile production technical field of mold.
Background technology
Thermoforming punching parts technology enters Chinese automobile manufacturing more than ten years, is always foreign enterprise in the core system of grasp
Make technology；Domestic hot forming tool production and processing just beginning 4 or five years, hot forming tool production technology also have greatly improved sky
Between.
Previous hot forming tool positioning pin is substantially above die insert, typically belongs to rigid structure, product
Positioning accuracy is poor.As thermoforming enters Chinese automobile manufacturing, competition is fiercer, to improve production efficiency and raising
Stock utilization, process program requirement more become more meticulous, it is necessary to have good mould positioning mechanism to ensure the essence of drop stamping product
Degree.
Utility model content
The technical problems to be solved in the utility model overcomes the defects of existing, provides a kind of hot forming tool detent mechanism,
Since, than cold stamping material softer, this utility model also functions to support and improves the excellent of product process conditions before drop stamping plate shaping
Point can be solved the problems, such as effectively in background technology.
In order to solve the above-mentioned technical problem, the utility model provides following technical solution：
The utility model provides a kind of hot forming tool detent mechanism, and including upper die and lower die, the upper mold includes upper mold
Plate, nitrogen cylinder cushion block, upper nitrogen cylinder, upper eccentric swage, positioning pin avoid holes and cavity plate；The nitrogen cylinder cushion block is mounted on described
One end of nitrogen cylinder, the other end of the upper nitrogen cylinder are connected with upper eccentric swage, and the top of the upper eccentric swage is equipped with positioning pin
Avoid holes；The lower die includes positioning pin, plate, punch-pin, lower eccentric swage, lower nitrogen cylinder and lower template；The one of the positioning pin
End is connected with plate, and the plate peace turns at the top of the lower eccentric swage, and the lower eccentric swage is mounted on the interior of the punch-pin
Portion, the lower end of the lower eccentric swage are connected with lower nitrogen cylinder.
As a kind of optimal technical scheme of the utility model, the positioning pin is used for the positioning of part.
As a kind of optimal technical scheme of the utility model, one end installation lower template of the lower nitrogen cylinder.
The advantageous effect that the utility model is reached is：A kind of hot forming tool detent mechanism, due to drop stamping plate into
Than cold stamping material softer before type, this utility model also function to support and improve product process conditions the advantages of.
Description of the drawings

Specific embodiment
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
Embodiment is selected to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment：- 3 are please referred to Fig.1, a kind of hot forming tool detent mechanism of the utility model, including upper die and lower die, institute
Stating upper mold includes cope plate 1, nitrogen cylinder cushion block 2, upper nitrogen cylinder 3, upper eccentric swage 4, positioning pin avoid holes 5 and cavity plate 6；The nitrogen
Cylinder cushion block 2 is mounted on one end of the upper nitrogen cylinder 3, and the other end of the upper nitrogen cylinder 3 is connected with upper eccentric swage 4, described
The top of upper eccentric swage 4 is equipped with positioning pin avoid holes 5；The lower die include positioning pin 7, plate 8, punch-pin 9, lower eccentric swage 10,
Lower nitrogen cylinder 11 and lower template 12；One end of the positioning pin 7 is connected with plate 8, and the peace of plate 8 turns in the lower eccentric swage
10 top, the lower eccentric swage 10 are mounted on the inside of the punch-pin 9, lower end and the lower nitrogen cylinder 11 of the lower eccentric swage 10
