Description

A two-station injection extension blow molding machine device

technical field

The utility model relates to a one-stage two-station injection extension blow molding machine device, in particular to a blow molding machine device for performing extension blow molding after preform injection molding without cooling, handling and storage.

Background technique

In the past bottle blowing method, after the preforms were injected and formed, they were cooled by conveyors or taken out by mechanical arms for cooling. After transportation and storage, it was easy to cause bacterial contamination before blow molding. After the preform is heated, it is blown and molded by the blow molding machine, so that the bottle container molding method is multi-stage, and the benefit is low. Today's vertical two-axis one-stage two-station extended blow molding device, the preform module The upper and lower devices are difficult to replace and the cost is high. Products with different shapes can only be produced after the hot runner system, mold base and modules are completely replaced. However, the utility model only needs to replace the injection mold and blowing mold. Bottle containers of different shapes can be produced after the modules are replaced, and the modules are upper and lower devices. If there is melt residue in the mold, it is not easy to clean.

Contents of the invention

The purpose of this utility model is to provide a two-station type injection extension blow molding machine device, which is a horizontal two-axis device and can be implemented in general melt plastic injection blow molding machines. The die, mandrel and extension rod are arranged horizontally, which is easy to operate and easy to replace. The opening of the injection mold is horizontal, which is easy to clean the residue of melt glue. Position, as a continuous production process, can produce large quantities of bottle containers quickly.

The utility model is to provide a two-station type injection extension blow molding machine device. The movable template and the rotating template are arranged in parallel to the left and right in sequence. The template frame is equipped with a core mold and an extension rod. The rotating template frame is equipped with two sets of the same bottle mouth moulds. The fixed template frame is equipped with an injection mold and a blowing mold. The molds correspond to each other, the extension rod and the bottle blowing mold are symmetrical to the other set of bottle mouth molds in the two sets of bottle mouth molds, and the rotating base is used for 180-degree rotation and positioning by the rotating template.

The utility model also provides a one-stage two-station injection extension blow molding machine device, the mandrel, the extension rod, two sets of bottleneck molds, injection molds, and bottle blow molds are all arranged horizontally. The utility model has the advantages of simple and convenient operation, easy disassembly and replacement of modules, easy cleaning of molten glue residues, and the rapid production of large quantities of bottle containers.

Detailed ways

In order to make the implementation and effect of the present utility model more remarkable, it is hereafter described in conjunction with illustrations and embodiments, to reveal its characteristics and purpose:

A section of two-station injection extension blow molding machine device of the utility model, please refer to Fig. 1 and 2, the movable template 1, the rotating template 2, and the fixed template 3 are arranged in parallel to the left and right in sequence, and the movable template 1 is erected with a core Die 11 (as shown in Figure 14) and extension rod 12 (as shown in Figure 15), the rotating formwork 2 is set up with two groups of identical flat dies 21, 22 (as shown in Figure 13), and the fixed formwork 3 is set up with a shot mold 31 (as shown in Figure 11) and bottle blowing mold 32 (as shown in Figure 12), and the left side of the rotating template 2 is connected to the axis of the rotating seat 7 of the support frame 6, and the rotating seat 7 can be used for 180-degree rotation and positioning , so that the two groups of bottle mouth molds 21 and 22 are transposed in the same direction, the mandrel 11, the first group of bottle mouth molds 21, and the injection molds 31 correspond to each other, while the extension rod 12, the second group of bottle mouth molds 22, and the blowing mold 32 correspond to each other (please refer to Figure 3). After the mold is closed, the first group of bottle mouth molds 21, core molds 11 and injection molds 31 are used to inject the melt through the injection pipe 4 according to the thermal runner 5. Form a preform p1 (as shown in Figure 4), after mold opening (please refer to Figure 5), the preform p1 remains on the first set of bottle mouth molds 21, and the injection mold 31 and the core mold 11 leave the preform p1, by The rotary template 2 is rotated, and the first and second groups of bottle mouth molds 21 and 22 are transposed (as shown in Figure 6). The second set of bottle mouth molds 22 corresponds to the mandrel 11 and the injection mold 31, and after the mold is closed (see Figure 7), the extension rod 12 extends to the finished embryo p1, and the air blow hole in the extension rod 12 is opened. After the bottle container p is blown, the extension rod 12 is retracted, so that the bottle container p is placed in the bottle blowing mold 32. At the same time, the second set of bottle mouth molds 22 are used for injection molding of the preform p2. shown), the bottle container p is demolded, and the preform p2 is left on the second set of bottle mouth molds 22, and the rotating template 2 is rotated back to its position again (as shown in Figure 10). Through the above-mentioned repeated actions, the continuous injection of the preform is achieved. The continuous automatic production of p1, p2 and extended blow molding container p achieves rapid molding. The output is large, and the modules are easy to disassemble and replace.
