Description
Technical Field
The invention relates to a mold opening and closing mechanism, in particular to a mold opening and closing mechanism applied to a bottle blowing machine.
Background
The PE bottle is manufactured by placing a bottle blank in a predetermined mold, and introducing gas into the bottle blank to expand and mold the bottle blank. The mold may then be opened to remove the molded bottle. Since the process of making the bottle requires the opening and closing member of the mold to be performed, a suitable opening and closing mechanism is needed.
The conventional mold opening and closing mechanism may be a link mechanism, such as a link-type mold opening and closing device disclosed in taiwan M402189 and a mold opening and closing device of a blow molding machine disclosed in M381514. However, the link mechanism is used as a mechanism for opening and closing the mold, which has the disadvantages of occupying a large amount of space and having a complicated structure.
Secondly, the conventional mold opening and closing mechanism may employ a cam mechanism. The cam mechanism is to carve a cam curve on the surface of a flat object, and one end of the mould is connected with the cam curve. When the flat object moves towards one direction, the cam curve can be used for driving the mould to form an open mould state; the plate object moves in the opposite direction to drive the mold to form a closed state. The cam mechanism is simpler than the link mechanism, but the reciprocating horizontal displacement of the plate-like object obviously still needs to occupy a larger space, and the driving mechanism or device for driving the plate-like object to displace needs to continuously operate in forward and reverse directions.

Referring to fig. 8, the cam driving system 50 has a first gear ring 58 on the outer surface of the first cylindrical roller 52 and a second gear ring 68 on the outer surface of the second cylindrical roller 62. In addition, the cam driving system 50 further includes a transmission gear assembly 70 and a motor assembly 80.

The motor assembly 80 is a motor 82 having an output end coupled to a drive gear 84, the drive gear 84 engaging the first drive gear 72. Thus, the motor 82 outputs a torque and transmits the torque through the form of gear engagement with each other, so that the first cylindrical roller 52 and the second cylindrical roller 62 rotate.
Referring to fig. 1 again, when the first mold 20 and the second mold 22 are aligned, the first abutting device 30 and the second abutting device 40 respectively form an abutting state, that is, the first baffle 322 and the first abutting baffle 340 form an end-face abutting form, and the second baffle 422 and the second abutting baffle 440 form an end-face abutting form. Referring to fig. 4, 5, 6 and 7, when the first abutting device 30 and the second abutting device 40 respectively form an abutting state, the first lifting guide 324 under the first sliding plate 320 (see fig. 5) is located at a protruding position 540 of the first lifting rail 54; similarly, the second lifting guide 424 under the second sliding plate 420 (see fig. 7) is located at the protrusion position 640 of the second lifting rail 64.
Referring to fig. 9 and 10, when the first cylindrical roller 52 and the second cylindrical roller 62 of the cam driving system 50 rotate, the first lifting guide 324 and the second lifting guide 424 are driven to descend by the curvature change of the first lifting rail 54 and the second lifting rail 64, respectively; at this time, the combination of the first slider plate 320 and the first barrier 322 and the combination of the second slider plate 420 and the second barrier 422 are simultaneously displaced downward. Thus, as shown in fig. 9, the first baffle 322 is in a state of being staggered in height with respect to the first leaning baffle 340; similarly, the second baffle 422 is in a staggered state with respect to the second leaning baffle 440.
Referring to fig. 11, the first cylindrical roller 52 and the second cylindrical roller 62 rotate, so that the first baffle 322 forms a high-low phase shift corresponding to the first leaning baffle 340, and the second baffle 422 forms a high-low phase shift corresponding to the second leaning baffle 440, and further synchronously drive the first movable mold base 16 to translate and lean against the first fixed mold base 10, and synchronously drive the second movable mold base 18 to translate and lean against the second fixed mold base 12, so that the first mold 20 and the second mold 22 can be opened, and the first baffle 322 and the first leaning baffle 340 can form a vertically overlapped form; similarly, the second baffle 422 and the second baffle 440 can be stacked up and down.
When the first mold 20 and the second mold 22 are opened, the operator can take out the finished product from the first mold 20 and/or the second mold 22 and place the finished product into the bottle blank to be formed again. Subsequently, when the first cylindrical roller 52 and the second cylindrical roller 62 rotate, the first movable die holder 16 and the second movable die holder 18 are displaced towards each other, the first die 20 and the second die 22 are aligned, the first baffle 322 of the first abutting device 30 abuts against the first abutting baffle 340, and the second baffle 422 of the second abutting device 40 abuts against the second abutting baffle 440.
According to the above description, the first lifting rail 54 and the second lifting rail 64 with cam mechanisms (cam action) are respectively formed on the end surfaces of the first cylindrical roller 52 and the second cylindrical roller 62, and the first displacement rail 56 and the second displacement rail 66 with cam mechanisms (cam action) are formed on the outer peripheral surfaces of the first cylindrical roller 52 and the second cylindrical roller 62, so that the first cylindrical roller 52 and the second cylindrical roller 62 rotate, and the first sliding plate 320 and the second sliding plate 420 can be synchronously moved up and down and the first movable die holder 16 and the second movable die holder 18 can be synchronously moved horizontally under the action of the cam mechanisms, so that the present invention can rapidly and conveniently open and mate the dies. In addition, the first cylindrical roller 52 and the second cylindrical roller 62 rotate in place, so the structure disclosed by the invention has the effect of reducing the space occupancy rate.
Referring to fig. 2, when the first mold 20 and the second mold 22 are aligned to perform product molding, a predetermined high pressure gas 90 can be introduced into the first fixed mold seat 10 and the second fixed mold seat 12. The predetermined high pressure gas 90 is used to push the first sliding plate 320 against the first movable mold base 16, so that the first blocking plate 322 is tightly abutted against the first abutting blocking plate 340; similarly, the predetermined high pressure gas 90 is used to push the second sliding plate 420 against the second movable mold base 18, so that the second baffle 422 is tightly abutted against the second abutting baffle 440.
On the contrary, when the predetermined high pressure gas is exhausted from the first fixed die holder 10 and the second fixed die holder 12, there is a slight gap between the first baffle 322 and the first leaning baffle 340, and there is a slight gap between the second baffle 422 and the second leaning baffle 440, so that the combination of the first sliding plate 320 and the first baffle 322 and the combination of the second sliding plate 420 and the second baffle 422 can smoothly generate the lifting displacement.
Referring to fig. 12, another embodiment of the present invention is the cam system 100 including a cylindrical roller 102 and a motor assembly 106.

Referring again to fig. 12, the motor assembly 106 is a motor 136 having an output coupled to a drive gear 138, the drive gear 138 engaging the ring gear 116. Thus, the motor 136 outputs a torque and transmits the torque through the gears to engage with each other, so that the cylindrical roller 102 is rotated.
Referring to fig. 14, the rotation of the cylindrical roller 102 drives a first sliding plate 140 of the first stopping device 122 and a second sliding plate 142 of the second stopping device 128 to move up and down, and drives the first movable mold base 126 and the second movable mold base 132 to move horizontally, so that the first mold 144 and the second mold 146 are closed and opened relatively.
