The specific embodiment

Describe the concrete structure and the operation principle of the Compression mould apparatus of the present invention's proposition in detail below in conjunction with accompanying drawing.

As shown in Figure 1, according to the Compression mould apparatus that the present invention proposes, comprise a upper die component 100 and following membrane module 200.

Referring to Fig. 1, Fig. 2 and Fig. 3, upper die component 100 is made up of parts such as guide pin bushing 1, water service pipe 2, spring 3, positioning sleeve 4, core rod 5, middle mould 6 and external molds 7, the bottom of core rod 5 is bigger, be provided with water service pipe 2 in the core rod 5, water service pipe 2 is deep into the bottom of core rod 5, and press the formation of the direction shown in arrow flow circuits among Fig. 3, to play the effect of cooling.Mould 6 in the socket outside the bottom of core rod 5, the shape of middle mould 6 bottom end faces is corresponding with the shape that gasket seal needs, for example, the shape on lip limit and the size of diameter, middle mould 6 is installed in outside the core rod 5 with positioning sleeve 4, outside the mould 6, the external diameter of external mold 7 lower ends was corresponding with the internal diameter of bottle cap 20 during external mold 7 was fixed on.Outside positioning sleeve 4, be with spring 3, push down the end face of external mold 7, also push down the step of core rod 5 lower ends simultaneously by middle mould 6 by spring 3, in the hole of the guide pin bushing 1 of then core rod 5 being packed into, and by the screw thread on water service pipe 2 tops, that core rod 5 is fastening and fuse with guide pin bushing 1.Guide pin bushing 1, water service pipe 2, spring 3, positioning sleeve 4, core rod 5, middle mould 6 and external mold 7 connect into an integral body by the screw in the top screw 19 like this.

Core rod 5, middle mould 6 and external mold 7 are major parts of compacting gasket seal, core rod 5 is that the middle part of compacting gasket seal is shaped, middle mould 6 is shaped in order to the perimeter lip shape of compacting gasket seal, and external mold 7 can outwards not overflow in order to the control plastics, guarantee the excircle dimension of gasket seal, size is consistent, perfect mouthful.3 cushioning effects of spring, external mold 7 compresses the bottom surface of bottle cap 20 all the time when matched moulds, and positioning sleeve 4 is the moving of mould 6 in the restriction then.Cling plastics in order to prevent that mould from generating heat, and guarantee the rapid shaping and demoulding of gasket seal, core rod 5 constantly cools off through water service pipe 2 circulations with cooling waters.

Referring to Fig. 1, Fig. 4 and Fig. 5, following membrane module 200 mainly is made up of parts such as counterdie 8, spring 9, bolster 10, bearing 11, roller 111 and transverse axis 15, also is linked to be an integral body.The top of counterdie 8 is embedded with gland 14, and gland 14 belows are provided with magnet steel 16, in order to bottle cap 20 magnetic are fixed on the top of counterdie 8, also can adopt other prior art, bottle cap is fixed on the top of counterdie 8.Spring 9 is sleeved on the middle part of counterdie 8, then counterdie 8 is inserted in the endoporus of bolster 10, and fixes with the screw (not shown).Bearing 11 is contained on the transverse axis 15, and transverse axis 15 passes the cross-drilled hole of bolster 10 bottoms simultaneously, also is provided with roller 111 on transverse axis 15.Spring 9 rigidity are bigger, can only play cushioning effect by micro-deformation.

In addition, in order to guarantee down moving up and down of membrane module 200, directional wheel 13 is screwed on the cylindrical of bolster 10 by screw thread, and be embedded in the locating slot 19 of die mould lower wall 40, slide up and down, guarantee that bolster 10 can not rotate, thereby make the bearing 11 all the time can be not crooked with contacting of cam 18.

As shown in Figure 5, express the rigging position of a Compression mould apparatus on make-up machine.The guide pin bushing 1 of upper die component 100 is installed on the die mould of moulding the pad make-up machine also can adjust upper-lower position by the number of adjusting pad on the dish 30, to adapt to the requirement for the treatment of the thin and thick of means of press seals pad.The outer end, counterdie 8 top of following membrane module 200 is socketed in the hole of die mould lower wall 40 by lining 17.The cam 18 that is positioned at bearing 11 lower ends cooperates with bearing 11 to promote bolster 10, and membrane module 200 is moved upward, and realizes the action with upper die component 100 matched moulds compacting gasket seal.In addition, the roller 111 other cams 12 that are positioned on the transverse axis 15 cooperate with roller 111, and the following membrane module 200 that has risen is moved downward, and cam 12 is disk edge cams.

As shown in Figure 6, the end face that is illustrated in the die mould lower wall 40 of moulding the pad make-up machine is provided with a plurality of holes, by lining 17 counterdie 8 is slidingly mounted in the hole of die mould lower wall 40.In the present embodiment, 24 holes that are evenly distributed in along die mould lower wall 40, be respectively charged into 24 following membrane modules 200, Dui Ying top is coaxial with it is provided with 24 upper die components 100, upper die component 100 and following membrane module 200 rotate (as shown in Figure 5) around the main shaft 300 of moulding the pad make-up machine simultaneously, upper die component 100 and following membrane module 200 revolutions are crossed certain angle, import a bottle cap 20, carry out matched moulds die mould, the demoulding, bottle cap 20 outputs then, overall process is all finished automatically, that is to say that upper and lower membrane module is finished the moulding of gasket seal in coaxial rotation.

Great advantage of the present invention is just can suppress as long as change various difform middle moulds Go out needed bottle cap sealing pad, it can be widely used in dissimilar moulding on the pad make-up machine, Its compression molding speed height, high productivity, long service life, adaptability is good.
