Production method of large-capacity cell shake flasks

Abstract

The invention discloses a production method of high-capacity cell shake flasks, and belongs to the technical field of plastic product production. The production problem of the high-capacity cell shake flasks is solved. Full-automatic integrated blow molding equipment with an injection molding device, an injection molding unit, a heating unit, a blow molding unit, a discharging unit and a conveying unit is used for production, through the adopted production equipment, production raw materials and production method, replicable batch production of finished cell shake flasks can be ensured, and the problem of shortage of large-capacity shake flasks in the market is solved; according to the process method, all procedures are tightly connected, and the production efficiency is improved; and by means of the method, parameters of segmented heating in the heating procedure and a blow molding mold in the blow molding procedure are optimized, the problem of one-time forming of the large-capacity shake flasks is solved, the method is beneficial to stable forming of the large-capacity shake flask, and stable performance of the finished shake flasks is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of plastic product production and relates to a production method of a large-capacity cell shaker flask. Background technique [0002] The specifications of cell shake flasks on the market are mostly small-capacity products below 1L, such as 125mL, 250mL, 500mL, and 1000mL. These small-capacity cell shake flasks are more suitable for experimental culture or pilot cell culture, but not suitable for For cell culture in production, production-oriented enterprises need large-capacity cell shake flask products to increase production capacity, so there is a demand for large-capacity cell shake flasks, and the current market cannot meet the demand for large-capacity cell shake flasks. [0003] Most of the existing shake bottles are plastic bottles formed by the extrusion blowing process. After the bottles using the extrusion blowing process are released from the mold, the excess glue needs to be removed mechanically...

AI Technical Summary

Problems solved by technology

[0002] The specifications of cell shake flasks on the market are mostly small-capacity products below 1L, such as 125mL, 250mL, 500mL, and 1000mL. These small-capacity cell shake flasks are more suitable for experimental culture or pilot cell culture, but not suitable for For cell culture in production, so for production enterprises that need large-capacity cell shake flasks to increase production capacity, there is a demand for large-capacity cell shake flasks, and the current market cannot meet the demand for large-capacity cell shake flasks

[0003] Most of the existing shake bottles are plastic bottles formed by the extrusion blowing process. After the bottles using the extrusion blowing process are released from the mold, the excess glue needs to be removed mechanically or manually, and some need to be polished and trimmed. There is a mold line clamp at the bottom, which makes the plastic shaker bottle lose its stability, and the processing technology is complicated, there are many procedures, and manual grinding and trimming are required

[0004] Existing patent No. 201080059124.7 is a preform for a large container, a large container, and a method for making a large container, which discloses a method for making a polyethylene terephthalate (hereinafter also referred to as PET) resin with a capacity of A preform for a large container of 10 liters or more, a large container, and a method for manufacturing a large container, but it is not suitable for the production of cell shaker flasks; there is also a blow molding method, a blow molding mold, and a patent No. 201980031157.1 Blow molding equipment, which discloses a blow molding equipment, including injection unit, injection unit, temperature adjustment unit, take-out unit and delivery device, but does not disclose the production method and production mold of the cell shaker flask
