Problems solved by technology

In comparison, this method has higher cooling efficiency, but it cannot cool the outer surface of the preform, resulting in relatively poor shape dimension accuracy and outer surface quality of the product
At the same time, unreasonable design will cause the cooling gas ejected from the co

Example Embodiment

[0042] Such as Figure 1A , 1B , 2A, 2B and image 3 As shown, it is a combined preform taking manipulator cooling device provided by the present invention, which is installed on one side of the injection molding machine. The injection molding machine has a reversible compound mold and a mold opening. When the mold is closed, a plurality of mold cavities can be formed. After the plastic melt is injected into the mold cavity and after a certain molding time, a plurality of preforms are formed, and the molds are removed by the robot device of the present invention after the mold is opened. The manipulator device is mainly composed of a translation device and a cooling cylinder cooling device. The translation device includes a servo motor 2, a frame 1, a linear guide 4 and a sliding table 3, etc. The sliding table 3 can reciprocate along the linear guide 4, among which, Position A is in the mold, and position B is the starting position. In the present invention, the starting positi...

Abstract

The present invention discloses a combined type preform taking and cooling manipulator and a method thereof. A cooling cylinder is arranged on the preform taking manipulator. A bottle preform pushed out by an ejector in a die cavity is cooled in the cooling cylinder on the manipulator for the first stage. When the manipulator moves to a position corresponding to a cooling pin, the cooling pin extends into the bottle preform and sprays gas (air) to carry out forced convection cooling for the inner surface of the bottle preform. The adoption of the novel combined cooling mode not only can ensure uniform cooling for the interior and the exterior of the bottle preform, but also can largely improve cooling efficiency. Meanwhile, the present invention adopts the design that the inner circulating pipe of the cooling cylinder integrates arch-shaped grooves and spiral grooves. The design improves the heat absorption area of the cooling cylinder, the volume of cooling fluid passing through the cooling cylinder and the cooling efficiency of the bottle preform, makes the integral cooling of the bottle preform more uniform, and improves the integral quality of the bottle preform.

Description

technical field [0001] The invention relates to a combined preform fetching and cooling device and method for solving the problems of preform fetching and cooling in the process of preform production by a preform injection molding machine. Background technique [0002] In the past, the preform injection molding machine formed a plurality of closed mold cavities when the mold was closed. After the plastic melt was injected and filled the mold cavity, after a predetermined period of standing and cooling, the preform was condensed and shaped, and the mold was opened. , the ejector mechanism pushes the preform out of the mold cavity, which completes the entire preform manufacturing process. [0003] However, in the above-mentioned preform injection molding machine, in order to prevent the injection-molded preforms from colliding with each other and damaging the preform appearance when they are demolded, the preforms need to be completely finalized, resulting in longer cooling ti...
