Description

Technical Field

[0001] The utility model relates to the technical field of the mold opening and closing of a bottle blowing machine, in particular to a multi-cam combined driving mold opening and closing device for a bottle blowing machine. Background Technique

[0002] In recent years, the beverage industry in China has developed rapidly, which has driven the rapid development of beverage machinery. Among them, the bottle blowing machine is a common machine for producing beverage bottles in beverage machinery factories. Among them, the mold opening and closing mechanism is one of the important factors affecting the output and stability of the bottle blowing machine.

[0003] The current traditional mold opening and closing device includes a mold base, left and right mold seats, left and right bottle body molds. The left and right mold seats are horizontally slidably installed on the mold base from left to right. The left bottle body mold is fixed on the left mold seat, and the right bottle body mold is fixed on the right mold seat. The left and right bottle body molds cooperate with each other. The left and right mold seats drive the mold opening and closing and mold locking by using four sets of connecting rod mechanisms. However, this structure has great disadvantages: two power sources are required to realize unlocking and locking, mold opening and closing, and the up and down movement of the bottom mold, which is likely to cause asynchronism of the power sources and result in failures. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1-7 , the present invention provides a technical solution: A combined cam drive opening and closing die device for a blow molding machine, including a lower fixing plate 21 installed at the top of the frame. On both sides of the top of the lower fixing plate 21, a first rear template 11 and a second rear template 12 are respectively installed. On the sides of the first rear template 11 and the second rear template 12 close to each other, a first boosting slide plate 13 and a second boosting slide plate 14 are respectively installed. On the first boosting slide plate 13 and the second boosting slide plate 14, a first boosting back plate 15 and a second boosting back plate 16 are respectively installed. On the first boosting back plate 15 and the second boosting back plate 16, a first die-locking slide plate 17 and a second die-locking slide plate 18 are respectively installed. On the sides of the first die-locking slide plate 17 and the second die-locking slide plate 18 close to each other, a first middle template 19 and a second middle template 20 are respectively installed. And a bottle mold is installed between the first middle template 19 and the second middle template 20;

[0024] On the side of the second rear template 12 away from the first rear template 11, a servo motor 6 is installed. The output end of the servo motor 6 is connected to a reducer 7, and the output end of the reducer 7 is connected to a driving main shaft 8. The driving main shaft 8 is located below the bottle mold, and a bottom die cam 3 is sleeved at the middle position of the driving main shaft 8. On both sides of the bottom die cam 3, a first clamping drive cam 1 and a second clamping drive cam 2 sleeved on the driving main shaft 8 are respectively provided. On the sides of the first clamping drive cam 1 and the second clamping drive cam 2 away from each other, a first die-locking cam 4 and a second die-locking cam 5 sleeved on the driving main shaft 8 are respectively provided.

[0025] In the present invention, a bottom die fixing plate 22 is installed at the bottom of the bottle mold, and a bottom die is installed on the bottom die fixing plate 22.

[0026] In the present utility model, the same upper fixing plate 10 is installed at the tops of the rear template one 11 and the rear template two 12.

[0027] In the present utility model, feet are installed at the four corner positions at the bottom of the frame.

[0028] In the present utility model, the die-locking cam one 4 and the die-locking cam two 5 are respectively connected to the die-locking slide plate one 17 and the die-locking slide plate two 18.

[0029] In the present utility model, the mold-closing driving cam one 1 and the mold-closing driving cam two 2 are respectively arranged corresponding to the middle template one 19 and the middle template two 20.

[0030] Working principle of the present utility model: The servo motor drives the speed reducer to drive the driving main shaft to rotate. When the driving main shaft rotates, the driving main shaft drives the die-locking cam to realize the up and down movement of the die-locking plate to unlock first; as the driving main shaft rotates, then the mold-opening driving cam drives the middle template to move backward to realize the mold-opening action. Finally, the driving bottom die cam moves downward to realize the downward movement of the bottom die, facilitating the translation and taking out of the formed bottle; after the bottle is taken out, the driving bottom die cam drives the driving bottom die roller to rise and reset. Then, the mold-closing driving cam drives the middle template to close. Finally, the die-locking cam drives the die-locking slide plate to move downward. With such a driving force, when the main shaft rotates 180°, the six actions of unlocking and locking, mold opening and closing, and up and down movement of the bottom die are realized in sequence with high speed and stability. The actions that originally required 2 power sources to be realized in the present utility model are reduced to be realized by one power source, thereby reducing the faults caused by the non-synchronization of the power sources and improving the production efficiency.
