Description

Technical Field

[0001] The utility model relates to the technical field of a four-in-one injection-blowing-filling-sealing machine, and specifically relates to a temperature-adjustable pre-blowing mold for a four-in-one injection-blowing-filling-sealing machine. Background Art

[0002] The injection-blowing-filling-sealing (IBFS) machine is a specialized piece of machinery. It utilizes a core-shooting machine to produce the core, which is then cured and then fed into a composite mold for a second, double-layer process. In short, this machine is ideal for high-speed, continuous production, meeting the demands of producing high-precision, high-quality plastic products. Before the blow molding process, the plastic product undergoes a temperature-controlled pre-blowing process to ensure part quality and production efficiency.

[0003] During the temperature-controlled pre-blowing process of a 4-in-1 injection-blowing-filling-sealing machine, if the mold closing process is not accurate, excessive pressure may be applied to a portion of the mold, causing deformation. This can affect the mold's sealing performance and, in turn, the quality of the plastic part. Therefore, we propose a temperature-controlled pre-blowing mold for the 4-in-1 injection-blowing-filling-sealing machine to ensure the accuracy of the closing process. Utility Model Content

[0004] The purpose of the utility model is to provide a temperature-adjustable pre-blowing mold for a four-in-one injection-blowing-filling-sealing machine to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a temperature-controlled pre-blowing mold for a four-in-one injection-blowing-filling-sealing machine, comprising a bottom plate, the upper surface of which is symmetrically fixedly connected to a base, the inner sides of two bases are symmetrically fixedly connected to hydraulic cylinders, the other end of the hydraulic cylinder is fixedly connected to a mold, the lower surface of the mold is in contact with the upper surface of the base, the upper surface of the base is symmetrically fixedly connected to columns, and the outer wall of the column is equipped with a blow molding head.

[0006] Preferably, it further comprises a guide structure, which is fixedly assembled on the upper surface of the base, and the central portion of the guide structure is fixedly connected to the upper surface of the mold.

[0007] Preferably, the guide structure includes side blocks, the number of which is six and which are symmetrically arranged in two rows vertically, the lower surface of the side blocks is fixedly connected to the upper surface of the base, and round rods are symmetrically fixedly connected between the inner side walls of the side blocks, and round hole blocks are sleeved on the outer walls of the round rods, and the lower surface of the round hole blocks is fixedly connected to the upper surface of the mold.

[0008] Preferably, a square rod is transversely fixedly connected to the center of the upper surface of the bottom plate, and the outer wall of the square rod is gap-fitted with the bottom of the mold.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: when performing the temperature adjustment pre-blowing link, the connecting rod drive mode is eliminated, which effectively saves space and makes the mold design and layout more concise. A greater clamping force is provided by hydraulic pressure, which is particularly important for the mold closing process. Too little clamping force may lead to incomplete mold closure or mold loosening during the production process. When damaged, the corresponding hydraulic cylinder can be quickly replaced. Compared with the mechanical drive mode, the components of the hydraulic system are generally easier to replace, which greatly shortens the maintenance time. The hydraulic cylinder provides power to push the mold to close, and a guide structure and a square rod are provided for guidance. The push of the hydraulic cylinder and the assistance of the guide device and the square rod achieve perfect mold closure, ensuring that the mold closing process is accurate. After the plastic part is fixed in the mold, the blow molding head on the top of the injection blow filling and sealing four-in-one machine is started, and the blowing end of the blow molding head is inserted into the plastic part to start the temperature adjustment pre-blowing link. During this process, the plastic part is blown and expanded in the mold. At the same time, the blow molding process will reduce the temperature of the plastic part. The temperature is adjusted by blow molding so that the plastic part reaches the optimal molding temperature. BRIEF DESCRIPTION OF THE DRAWINGS
