Problems solved by technology

[0003] During the production of the preform, a sprue column for connecting the suspension ring will be designed at the bottom of the preform (for details, please refer to the patents with publication numbers CN208464644U and CN208428518U), but the existing preforms have the following deficiencies during production: 1. The column is a cylindrical structure, which will generate air bubbles when injecting glue, which will affect the product quality; 2. The cylindrical gate column has a small heat dissipation area, so the intermediate material is not easy to cool, which seriously affects the production efficiency and production cycle. There will be wire drawing, which will further affect product quality; 3. When blowing, the preform is a unilateral support structure that is only supported by the connection key connecting the sprue column and the lifting ring. bottle effect

Embodiment 1

[0032] Such as figure 1 and figure 2 As shown, a ring-integrated preform with a large cooling area of ​​the rubber mouth column includes a preform body 1, a suspension ring 2 and a rubber mouth column 3; the rubber mouth column 3 is arranged at the closed end of the preform body 1, The lifting ring 2 is connected to the rubber mouth column 3 through the connecting part 7, and the connecting part 7 is non-linearly arranged in the space formed between the rubber mouth column 3 and the lifting ring 2;

[0033] The glue hole post 3 is a special-shaped column structure with a cooling area larger than the cylindrical glue port post 3 .

[0034] The cross-section of the rubber port post 3 is tooth-shaped.

[0035] The rubber mouth column 3 is cylindrical, and the rubber mouth column 3 is evenly distributed with 6 cooling grooves 4 along the circumference, and protruding teeth 5 (6 teeth) are formed between two adjacent cooling grooves 4 .

[0036] The preform body 1, the rubber m...

Embodiment 2

[0042] Such as image 3 As shown, the difference between this embodiment and embodiment 1 lies in that the glue port post 3 is a prism.

[0043] It is preferably a regular five or hexagonal prism. The surface area of ​​the prism is greater than the surface area of ​​the cylinder. Furthermore, the cooling area of ​​the prismatic rubber mouth column 3 is larger, the heat dissipation effect is better, and it is not easy to draw.

Embodiment 3

[0045] Such as Figure 4 and Figure 5 As shown, the present embodiment is a forming mold for producing the ring-integrated preform with a large cooling area of ​​the rubber port post in Example 1, including a core 8, a core sleeve 9, a first half block 10, a forming Die 11, second half block 12 and gate mold core 13, the bottom center of gate mold core 13 is provided with injection port 14, the bottom of gate mold core 13 is provided with second half block 12, gate mold The mating surface of the core 13 and the second half block 12 forms the forming cavity of the suspension ring 2 and the connecting part 7, and one end of the forming cavity of the lifting ring 2 communicates with the forming cavity of the connecting part 7; the bottom of the gate core 13, the second half The molding cavity of the plastic mouth column 3 is formed between the top of the block 12 and the top of the core 8, and the molding cavity of the plastic mouth column 3 is connected with the molding cavity...

Abstract

The invention discloses a hanging ring integrated bottle preform large in cooling area of a pouring gate column. The hanging ring integrated bottle preform comprises a bottle preform body, a hanging ring and the pouring gate column. The pouring gate column is arranged at the closed end of the bottle preform body, the hanging ring is connected with the pouring gate column through a connecting part, and the connecting part is arranged in a space formed between the pouring gate column and the hanging ring in a non-linear manner. The pouring gate column is of a special-shaped column structure with a cooling area larger than that of a cylindrical pouring gate column. By means of the bottle preform, the heat dissipation area of the pouring gate column is increased, the heat dissipation area of the pouring gate column is increased, then the heat dissipation rate is increased, the whole production period is shortened, the production efficiency is improved by 20%, and bubbles and wiredrawing are avoided.

Description

technical field [0001] The invention relates to the technical field of hanging bottle preforms, in particular to a ring-integrated preform with a large cooling area of ​​a rubber port post and a forming mold thereof. Background technique [0002] At present, the plastic infusion bottle has gradually replaced the traditional glass infusion bottle, and the bottom of the plastic infusion bottle needs a suspension ring, which is convenient to hang on the fixed hook when in use. Generally, the bottom of the plastic infusion bottle will be equipped with a suspension ring structure, so that it is no longer necessary to use other auxiliary structures (such as net pockets, fixing frames, etc.) to hang; At present, the blank parts are mainly processed and formed by injection molding process. [0003] During the preform production, a sprue column for connecting the suspension ring will be designed at the bottom of the preform (for details, please refer to the patents with publication ...
