However, the existing cooling water inlet and outlet holes are all arranged on the bottom mold, therefore, the water pipe joints are all connected on the bottom mold. Since different preforms are blown during the production process, different bottom molds need to be replaced. Therefore, it is necessary to It is inconvenient to reconnect the water pipe joint

Embodiment Construction

[0010] A blow molding machine base mold, such as figure 1 and figure 2 As shown, it includes a quick-change base body 1, a pair of male joints 21 are inserted into the bottom surface of the quick-change base body 1, a bottom core seat 2 is connected to the upper surface of the quick-change base body 1, and a connecting bottom core is arranged on the upper surface of the bottom core seat 2. The water inlet hole 3 and the water outlet hole 4 of the inner pipeline of the seat 2 are also connected with a bottom core 6 with a bottle bottom cavity 5 on the upper surface of the bottom core seat 2, and the bottom surface of the bottom core 6 is connected with the upper surface of the bottom core seat 2. There is a space 7 for water flow between them, and the water inlet hole 3 and the water outlet hole 4 on the bottom core base 2 communicate with the corresponding male joint 21 on the quick-change base body 1 through pipelines respectively.

Abstract

The invention discloses a bottle blowing machine bottom die. Two male joints on a rapid changing base body and female joints on a specific bottom die locking mechanism are rapidly dismounted and mounted, rapid replacing of the bottom die is quite facilitated, a water inlet and a water outlet are formed in a bottom core base, and communicate with the corresponding male joints on the rapid changingbase body through pipelines, due to the fact that the male joints are in abut joint with the female joints on the bottom die locking mechanism, and a water pipe joint is connected to the female jointson the bottom die locking mechanism, cooling water can flow into the space between the bottom face of a bottom core and the upper surface of a bottom core base from the bottom die locking mechanism,a blown bottle blank bottom is cooled, and used water flows back to the other female joint of the bottom die locking mechanism again to flow out. Through female and male joint connection and pipelinearranging, the water pipe joint is led to the bottom die locking mechanism, the bottom die locking mechanism does not need to be frequently replaced, during bottom die replacing, operation of water pipe joint re-connection is avoided, and bottom die rapid replacing is facilitated.

Description

technical field [0001] The invention relates to a bottom mold of a bottle blowing machine. Background technique [0002] The bottom mold in the bottle blowing machine is connected to the bottom mold locking mechanism, which is mainly used to assist the bottom molding of the preform. During the bottle blowing process, the lower surface of the bottom mold needs to be cooled by cooling water to further cool the bottom of the preform to prevent the bottom of the bottle from sticking to the bottom mold due to high temperature, resulting in failure to demould. However, the existing cooling water inlet and outlet holes are all arranged on the bottom mold, therefore, the water pipe joints are all connected on the bottom mold. Since different preforms are blown during the production process, different bottom molds need to be replaced. Therefore, it is necessary to It is inconvenient to reconnect the water pipe joint. Contents of the invention [0003] The invention aims to provid...
