[0016] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0017] like Figures 1 to 2 As shown, in this embodiment, a fully electric opening and closing mold includes a mold shifting base 1, an electric cylinder bracket 2, a front mold base 3, a rear mold base 4 and a driving electric cylinder 5. A movable slide rail 6 is fixed on the mold shifting base 1 along the front and rear directions. The lower end of the electric cylinder bracket 2, the lower end of the front mold base 3 and the lower end of the rear mold base 4 are all equipped with a movable slider 7. The movable slider 7 slides on the movable slide rail 6. The driving electric cylinder 5 is fixed on the electric cylinder bracket 2. The driving end of the driving electric cylinder 5 is connected to the rear end of the rear mold base 4. A U-shaped connecting plate 8 is connected between the electric cylinder bracket 2 and the front end of the front mold base 3. The two U-shaped connecting plates 8 are respectively located on both sides of the mold shifting base 1.

[0018] The mold transfer base 1 is installed on the blow molding machine. After the driving electric cylinder 5 is started, the driving end of the driving electric cylinder 5 controls the rear mold base 4 to move forward and backward. At the same time, the electric cylinder bracket 2 used to install the driving electric cylinder 5 is linked with the U-shaped connecting plate 8 to make the front mold base 3 move forward and backward. The movement directions of the front mold base 3 and the rear mold base 4 are opposite, and the speed is consistent, ensuring that the product position at the center position is opened and closed at the same time, and the movement of the front mold base 3 and the rear mold base 4 relies on the same moving slide rail 6, which makes the movement convenient and labor-saving.

[0019] A mold shifting gear seat 9 is fixed on the mold shifting base 1, and the middle part of the mold shifting gear seat 9 is rotatably connected to the driving gear. A first rack rod 10 is fixed on the electric cylinder bracket 2, and a second rack rod 11 is fixed on the rear mold base 4. The first rack rod 10 and the second rack rod 11 are respectively located on both sides of the driving gear and are engaged with the driving gear for transmission.

[0020] The relative movement of the front mold base 3 and the rear mold base 4 needs to be at the same speed. On the fixed mold shifting gear base 9, the driving gear simultaneously drives the first rack rod 10 and the second rack rod 11 to move in opposite directions. The first rack rod 10 controls the movement of the electric cylinder bracket 2, and then controls the movement of the front mold base 3. The second rack rod 11 controls the movement of the rear mold base 4.

[0021] A first connecting shaft 12 is installed at the upper end of the electric cylinder bracket 2, a second connecting shaft 13 is installed on the front mold base 3, both ends of the U-shaped connecting plate 8 are connected to the first connecting shaft 12 and the second connecting shaft 13 respectively, a third connecting shaft 14 is installed on the rear mold base 4, and the driving end of the driving electric cylinder 5 is connected to the third connecting shaft 14. Under the action of the connecting shaft, maintenance and replacement are more convenient.

[0022] A transverse sliding block 15 is fixed to the lower end of the mold transfer base 1 , and the transverse sliding block 15 can drive the mold transfer base 1 to perform transverse movement of the mold set.

[0023] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present invention and the technical principles used. Within the technical scope disclosed by the present invention, any changes or replacements that can be easily thought of by technicians familiar with this technical field should be included in the scope of protection of the present invention.
