Description

Technical Field

[0001] The utility model relates to a demoulding device for blow-molded products, in particular to a demoulding device for horizontally placed blow-molded products. Background Art

[0002] As Figure 1 shown, in a traditional three-station injection blow molding device, its product 9 is usually injection blow molded in a horizontally placed manner. Its working process is as follows: the product 9 is injection molded into a preform at the injection station I, and the preform enters the blow molding station II through the rising and rotation of 120° of the turret 1. Then, the turret 1 descends, and the preform is blow molded into a product through compressed air at the blow molding station II. After the formed product 9 enters the demoulding station III through the rising and rotation of 120° of the turret 1, then the turret 1 descends, and the formed product 9 falls into the demoulding plate 7. Then, under the action of the demoulding device, the product 9 is separated from the mandrel 8 (see Figure 2 shown), and then, the demoulding plate 7 is flipped by 90°, and the product 9 falls off. The disadvantages of this traditional demoulding device are as follows:

[0003] 1. During the process of the product 9 being separated from the mandrel 8, since it is in clearance fit with the demoulding plate 7, during the process of separating from the mandrel 8, the product 9 will sag due to the action of gravity, resulting in the mouth (bottle mouth) of the product 9 coming into contact with the mandrel 8 again. Since the mandrel 8 is in a high-temperature state, at this time, the product 9 will be damaged due to friction with the mandrel 8.

[0004] 2. During the trial production of the injection blow molding device, the product 9 may not be fully formed. At this time, it is very difficult to separate the unformed product 9 from the mandrel 8 by relying on the demoulding plate 7, and it can only be manually peeled off after the machine is stopped, which greatly reduces the production efficiency.
