Changing shaping mould 24（Side mould 241）Afterwards, corresponding stretching head 13 can as needed be changed.
The inner edge of the lower end of upper cut-off-die 12 is upper shearing knife edge, and the outer rim of the lower upper end of cut-off-die 23 is down cut blade, down cut
Blade matches with upper shearing knife edge.
The operation principle of brief description once this hot forming tool：
When making plastic containers, plastic sheet is heated first, plastic sheet is reached forming temperature；By the modeling heated
By forming area, now hot forming tool matched moulds, compression spring 18 applies downward thrust, makes pressure media sheet to binder ring 17
Be pressed on sheet material on the upper surface of lower cut-off-die 23 by material ring 17, and shaping gas is formed between the cavity of plastic sheet and upper cut-off-die 23
Room；Then stretch rod installing plate lifting control mechanism drives stretch rod installing plate 15 to decline, stretch rod installing plate 15, stretch rod
14th, stretching head 13 declines together；Stretching head 13 is pre-stretched to plastic sheet；Then compressed air enters above-mentioned shaping air chamber
In, in the presence of compressed air, plastic sheet is close to shaping mould 24, is molded plastic sheet；Subsequent stretch rod installing plate liter
Drop controlling organization drives stretch rod installing plate 15, stretch rod 14, stretching head 13 to rise together, and stretching head 13 returns back to cut-off-die 12
Cavity in；Then descend mould 2 further up, down cut blade and the lower end inner edge of upper cut-off-die 12 of the upper end outer rim of lower cut-off-die 23
Upper shearing knife edge coordinates, and the formed sheet after setting is sheared, and plastic containers are cut out coming from formed sheet, obtains
The single plastic containers with hole；Then lower mould 2 declines, and the edge of plastic containers leaves binder ring 17；Knock-pin installing plate
212nd, knock-pin 211 and movable die block 242 rise, and plastic containers are ejected；Then can be dried to plastic containers, plastics are held
Device blows off hot forming tool, so as to complete one-step hot moulding process.Subsequent knock-pin installing plate 212, knock-pin 211 declines and band
Dynamic movable die block 242 drops to position needed for shaping, prepares thermoforming process next time.
This hot forming tool is equipped with multiple sides mould 241, a kind of plastic containers of each side mould 241 correspondence；Movable die block 242 is only
Configuration is a set of, can be supporting with each side mould 241, and so, when repacking hot forming tool is needed, only need to more change sides mould 241, and
Movable die block 242 need not then be changed.
When to produce wherein certain plastic containers, corresponding side mould 241 need to be only installed in lower mold body 22（If under
Other side moulds 241 are housed originally on die body 22, are then first dismantled down original side mould 241）.The handling method of side mould 241 is as follows：
When needing to install side mould 241, make each slot 26 of side mould 241 and each position alignment of slotting key 25, be then inserted into each slotting key 25
In corresponding slot 26, you can side mould 241 is installed in lower mold body 22（The slotting key 25 of two bar shapeds inserts left slotting key and houses respectively
After in groove 27-1 and right slotting key storage tank 27-2, rotate two and insert key grabs 29, slotting key grab 29 is embedded on corresponding slotting key 25
Draw-in groove 210 in, you can the position of slotting key 25 is locked）；When side mould 241 is unloaded, each slotting key 25 only need to be extracted（Rotate
Two insert key grab 29, slotting key grab 29 is mutually disengaged with the draw-in groove 210 on corresponding slotting key 25, you can slotting key 25 is inserted from a left side
Extracted in key storage tank 27-1, right slotting key storage tank 27-2）, slotting key 25 is departed from each slot 26, you can to remove side mould 241.
In other embodiments, lower mold body is framework（Generally rectangular framework）, the upper surface of lower mold body is provided with least
Three slotting key storage tanks, each slotting key storage tank one end open is opened on lower mold body madial wall in lower mold body lateral wall, the other end（Peace
After loading cut-off-die, each slotting key storage tank top is closed by lower cut-off-die）；Slotting key storage tank is identical with slotting bond number amount and corresponds,
The slotting key is bar shaped and inserts key, inserts key and is arranged in corresponding slotting key storage tank, and the inner end for inserting key is insert molded mould outer wall
In upper corresponding slot.Generally, above-mentioned slotting key storage tank is respectively arranged in the different edge of lower mold body, makes to insert bond energy enough to shaping mould
Form reliable support.More preferably in scheme, the outer end of above-mentioned slotting key is provided with handle, so that operating personnel operate.It is more preferably square
It is rotatably mounted on the lateral wall of above-mentioned lower mold body to there are at least three to insert key grab in case, insert key grab identical with slotting bond number amount
And correspond；The outer end for inserting key is provided with draw-in groove（Draw-in groove can be along the circumferentially disposed annular groove of slotting key）, draw-in groove with it is corresponding
Key grab is inserted to be engaged by clamping.After each slotting key is inserted in corresponding slotting key storage tank respectively, rotate two and insert key grab, make to insert key grab
In draw-in groove on the corresponding slotting key of insertion, you can lock the position of slotting key；When needing to take out slotting key, rotate two and insert key cards
Hook, makes slotting key grab be mutually disengaged with the draw-in groove on corresponding slotting key, you can slotting key is extracted from slotting key storage tank.
