Description

Technical Field

[0001] The utility model relates to the technical field of plastic bottle production, in particular to a green and environmentally friendly plastic bottle forming mold. Background Art

[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. Plastic bottles widely use polyester, polyethylene, and polypropylene as raw materials. After adding corresponding organic solvents, they are heated at high temperatures and then blow-molded, extruded, or injection-molded through plastic molds to form plastic containers.

[0003] The existing plastic bottle molding mold has a poor fixing effect on the plastic cup embryo, resulting in poor molding effect. At the same time, the traditional plastic bottle injection molding method directly injects raw materials into the mold, which will lead to excessive injection of raw materials and waste, and lacks the concept of energy saving and environmental protection. In order to solve the shortcomings of the existing technology, we propose a green and environmentally friendly plastic bottle molding mold. Utility Model Content

[0012] Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, the pre-forming column mold can be used to pre-form the plastic bottle raw materials. The plastic raw materials are injected into the pre-forming column mold through the injection port. The liquid raw materials wrap the embryo stem to form a hollow plastic cup embryo. The plastic cup embryo is then transported to the forming mold for blow molding. The materials used in the injection molding process can be accurately controlled, the molding effect is good, and it is conducive to promotion and use.

[0015] 2. In the present invention, the upper mold can be quickly moved between the preforming column mold and the forming mold by means of a hanger. When the plastic cup embryo is formed in the preforming column mold, the lifting arm is lifted and the hanging arm can be used to move the lifting arm horizontally to the upper end of the forming mold, thereby placing the plastic cup embryo between the two sets of forming molds, avoiding the plastic cup embryo being exposed to the outside for too long and being difficult to blow mold and stretch, making the device more practical.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] Example 1, as Figure 1-2 As shown, a green and environmentally friendly plastic bottle molding mold, during the injection molding process, the staff connects the injection tube to the injection port 2 on the outer wall of the preformed column mold 1, and injects plastic raw materials into the preformed column mold 1. The upper mold 4 at the upper end of the preformed column mold 1 is connected to the preformed column mold 1 through the connecting pipe port 3, so that the embryonic stem 17 at the lower end of the upper mold 4 extends into the preformed column mold 1. The liquid raw material injected into the preformed column mold 1 wraps the embryonic stem 17 to form a hollow plastic cup embryo 18, and the preforming is completed in the preformed column mold 1. After shaping, the plastic cup embryo 18 can be transported to the forming mold for molding through the transportation structure, and the lifting arm 5 at the upper end of the upper mold 4 is lifted. The sliding block 9 connected to the lifting arm 5 can slide on the upper end of the hanger 7 through the slide rod 8, thereby driving the lifting arm 5 to move horizontally, so that the lifting arm 5 can move the upper mold 4 and the plastic cup embryo 18 connected to it to the upper end of the forming mold, and then place the plastic cup embryo 18 between the two sets of forming molds to avoid the plastic cup embryo 18 being exposed to the outside for too long and difficult to blow mold and stretch.

[0023] Example 2, as Figure 1-4 As shown, a green and environmentally friendly plastic bottle molding mold, when performing the molding process, lower the lifting arm 5, start the extruders 10 at both ends, and the extruders 10 drive the No. 1 molding mold 13 and the No. 2 molding mold 14 to move respectively by pushing the push rods 12 in opposite directions. The two sets of molding molds can slide on the upper end of the base 11 using the slide rails 19 connected at the bottom. When the two sets of molding molds are close together, the plastic cup embryo 18 is fixed inside the mold, and then blow molding can be carried out to stretch the plastic cup embryo 18 into the shape of a cup inside the mold. Release the embryo rod 17, leaving the processed plastic cup to complete the molding process, so that the materials used in the injection molding process can be accurately controlled, the molding effect is good, and the practicality of the device is higher.

[0024] How it works

[0025] It should be noted that the present invention is a green and environmentally friendly plastic bottle forming mold. When in use, the staff connects the injection tube to the injection port 2 on the outer wall of the preforming column mold 1, and injects the plastic raw material into the preforming column mold 1. The upper mold 4 at the upper end of the preforming column mold 1 is connected to the preforming column mold 1 through the connecting pipe port 3, so that the embryonic rod 17 at the lower end of the upper mold 4 extends into the preforming column mold 1, and the liquid raw material injected into the preforming column mold 1 forms a hollow plastic cup embryo 18 by wrapping the embryonic rod 17. After the preforming is completed in the preforming column mold 1, the lifting arm 5 at the upper end of the upper mold 4 is lifted, and the sliding block 9 connected to the lifting arm 5 can slide on the upper end of the hanger 7 through the sliding rod 8, thereby The lifting arm 5 is driven to move horizontally, so that the lifting arm 5 can move the upper mold 4 and the plastic cup embryo 18 connected to it to the upper end of the molding mold, and then the plastic cup embryo 18 is placed between the two sets of molding molds, the lifting arm 5 is lowered, and the extruders 10 at both ends are started. The extruders 10 respectively drive the No. 1 molding mold 13 and the No. 2 molding mold 14 to move by pushing the push rods 12 in opposite directions. The two sets of molding molds can slide on the upper end of the base 11 using the slide rails 19 connected at the bottom. When the two sets of molding molds are close together, the plastic cup embryo 18 is fixed inside the mold, and then blow molding can be performed to stretch the plastic cup embryo 18 into the shape of a cup inside the mold, release the embryo rod 17, and leave the processed plastic cup to complete the molding process.
