Problems solved by technology

[0003] At present, in traditional stack molds, in order to maintain synchronization, a two-way cylinder is generally used to control the opening and closing of the hot runner. However, in actual work, sometimes the elongation of the valve needle or cylinder shaft is fine-tuned according to the actual situation. , to meet the actual needs, but the inventor found that the number of two-way cylinders on the actual market is small and not easy to obtain. The adaptability is poor and needs to be further improved

Embodiment Construction

[0033] The application will be described in further detail below in conjunction with the accompanying drawings.

[0034] The embodiment of the present application discloses a stack mold coaxial valve needle system, such as figure 1 As shown, it includes: mounting base 1, the mounting base 1 is I-shaped as a whole, and a plurality of mounting tubes 2 are symmetrically installed on both sides of the mounting base 1, and two mounting tubes 2 form a group. In this embodiment, there are multiple A hot runner is arranged in the installation cylinder 2, and an injection runner is also arranged in the installation seat 1. The injection runner is connected with the hot runner, and a valve needle 20 is also arranged in the hot runner, and the valve needle 20 is used for starting Close the opening of the hot runner.

[0035] Among them, such as figure 2 and image 3 As shown, a driving mechanism 3 is installed on the mounting seat 1, the output end of the driving mechanism 3 is inser...

Abstract

The application discloses a stack mold coaxial valve needle system, which includes: a mounting seat; a mounting cylinder symmetrically installed on the mounting seat and having a hot runner inside; detachably mounted on a predetermined position of the mounting seat through a fixing component A driving mechanism for driving the valve needle to move along the inner wall of the installation cylinder to open and close the opening of the hot runner; and a connecting piece detachably installed between the output end of the driving mechanism and the valve needle for connecting the two. The application can conveniently adjust the elongation of the cylinder shaft and the valve needle according to the actual situation, so as to improve the compatibility with the hot runner, thereby increasing the scope of application of the application.

Description

technical field [0001] The invention relates to the field of stack mold valve needles, in particular to a stack mold coaxial valve needle system. Background technique [0002] In the injection molding industry, stack molds are often used. A common stack mold is usually made of two single-layer molds installed back to back, and the parting surface is usually opened synchronously by a gear and rack mechanism. [0003] At present, in traditional stack molds, in order to maintain synchronization, a two-way cylinder is generally used to control the opening and closing of the hot runner. However, in actual work, sometimes the elongation of the valve needle or cylinder shaft is fine-tuned according to the actual situation. , to meet the actual needs, but the inventor found that the number of two-way cylinders on the actual market is small and not easy to obtain. The adaptability is poor and needs further improvement. Contents of the invention [0004] The purpose of this applic...
