Mould, shaping mould are mounted in lower template, and shaping mould has the shaping mold cavity of a upper end opening.
The thermoforming of plastic sheet generally uses on assembly line at present, in order to ensure stretching effect of the sheet material in thermoforming
Fruit, the sheet material that processes have higher temperature, and original sheet material can be intermediate sagging, and when molding deposits per cave air inflow with inlet period
It is pullled mutually between each cave in priority shutdown, molding, causes product became uneven even, so as to influence the quality of product.
Utility model content
The purpose of this utility model is to provide a kind of hot forming tools of multi-stage gas circuit structure, are opened from the inlet end of mold
It is identical to begin to the gas circuit distance of each cavity, from maximum hole is started until venthole enters cavity, according to level-one one
Grade distribution is gone down, and upper level air flue is divided into two-way next stage air flue, then the next stage sectional area of air passage of two-way is added summation etc.
In 1.4 to 2 times of upper level air flue, so that it is guaranteed that the gas reached per cave is consistent to a certain extent.
Following technical scheme is used to achieve the above object：
A kind of hot forming tool of multi-stage gas circuit structure, including upper die and lower die；Upper mold include cope plate, upper die body, into
Type head, upper die body are mounted on cope plate, and upper die body has the cavity of a lower ending opening, and upper die body enters equipped with compressed gas
Inlet channel, inlet channel connects with the cavity of upper die body, and moulded head is set in the cavity of upper die body；Lower die includes lower template
And shaping mould, shaping mould are mounted in lower template, shaping mould has the shaping mold cavity of a upper end opening；It is characterized in that：It is described
Upper die body include connecting plate connected up and down and fixed plate, several equally distributed ventholes are offered in fixed plate,
Several uniform air admission holes are installed on the connecting plate, while air inlet duct is also installed in the bottom surface of connecting plate, when even
Be bonded at the top of fishplate bar bottom surface and fixed plate when being connected, air inlet duct forms an inlet channel, described inlet channel one end and into
Stomata communicates, and the other end is connected with venthole, and the distance of inlet channel is identical between each venthole and air admission hole.
The inlet channel is multistage air flue, is gone down according to the distribution of level-one level-one, upper level air flue is divided into one under two-way
Grade air flue, then this wants the next stage sectional area of air passage of two-way to be added 1.4 to 2 times that summation is equal to upper level air flue.
The utility model opens up in connecting plate bottom surface and puts Multi-stage inlet slot, is bonded to form air inlet by connecting plate and fixed plate
Road, compressed gas enter from the air admission hole for starting maximum hole in air intake duct, by multistage air flue until each venthole into
Enter cavity, go down according to the distribution of level-one level-one, upper level air flue is divided into two-way next stage air flue, then the next stage air flue of two-way
Sectional area is added 1.4 to 2 times that summation is equal to upper level air flue, and the path between air admission hole and venthole is identical, so as to
The tolerance for ensuring to reach each cavity is consistent, so that molding product thickness consistency is preferable.

Specific embodiment
As shown in Figs 1-4, a kind of hot forming tool of multi-stage gas circuit structure, including upper mold 1 and lower die 2；Upper mold 1 includes upper
Template 11, upper die body 12, moulded head, upper die body 12 are mounted on cope plate 11, and upper die body 12 has the cavity of a lower ending opening,
Upper die body 12 is equipped with the inlet channel that compressed gas enters, and inlet channel is connected with the cavity of upper die body 12, and moulded head is set on
In the cavity of upper die body 12；Lower die 2 includes lower template 21 and shaping mould 22, and shaping mould 22 is mounted in lower template 21, shaping mould
22 have the shaping mold cavity of a upper end opening；It is characterized in that：The upper die body 12 includes 121 He of connecting plate connected up and down
