Abstract

PURPOSE:To attain to prevent the core misalignment of a coupler, by mounting a movable connection plate to the leading end of the core misalignment in three up-and-down, left-and-right and before-and-behind axial directions and made connectable to said leading end of the piston rod. CONSTITUTION:A coupler 15 is provided to the connection plate 13 mounted to a mold 12 so as to correspond to a movable connection plate 14 having a water supply or drain hose mounted thereto. The movable connection plate 14 is mounted to the piston rod 17 of a cylinder 16 having self-falling preventing function through a floating connector 18 absorbing core misalignment in three up-and-down, left-and-down and before-and-behind axial directions and made connectable to said leading end of the piston rod 17. By this constitution, becaase the movalg connection plate 14 can be freely adjusted in matching relation to the connection plate 13, certain connection is enabled and the coupler 15 is naturally engaged and no operational inferiority is also generated.

Description

[Detailed description of the invention] [Field to which the invention pertains] The present invention relates to a mold pipe connection device for an injection molding machine or the like.

[Prior art and its drawbacks]

The mold of an injection molding machine is connected to a reservoir hose for cooling the mold, a drain hose, a reservoir hose for supplying oil to a hydraulic core cylinder, a reservoir hose for draining oil, and the like. In the past, these connections and removals were done manually, but as mold shapes have become more complex and larger, the work has become cumbersome and time-consuming. Various devices have been invented and devised to perform this.

However, common problems with conventional equipment are the type of mold,
The disadvantage is that the coupler may become misaligned due to positional deviation due to slight changes in the mounting position. Many devices have good horizontal adjustment, but poor vertical and longitudinal adjustment. It is necessary to make fine adjustments to ensure that the coupler fits properly each time the mold is installed, and this work takes a lot of time.

If there is a misalignment in the coupler, the life of the coupler will be shortened due to malfunction, galling, etc. Generally, the centering accuracy required for coupler connection is said to be within ±0.1 to 0.2 m.

[Purpose of the invention]

It is an object of the present invention to provide a mold conduit connecting device that eliminates the drawbacks of the conventional devices described above and completely solves the problem of misalignment of couplers.

[Key points of the invention]

) In order to achieve the above-mentioned object, the present invention provides an L-shaped bracket attached to a mold mounting board of an injection molding machine, etc., a cylinder having a function of preventing falling due to its own weight attached to this bracket, and a piston of this cylinder. Attached to the mouth, top and bottom,
A movable connecting plate is attached to the movable connecting plate via a floating connector, which absorbs misalignment in the left and right, front and rear directions, and enables connection.One end is attached to the movable connecting plate via the floating connector, and the other end is attached to the From a connection bundt equipped with multiple guide bars that pass through guide holes provided in the bracket and are locked to the connection plate, and couplers provided at locations corresponding to the couplers on the movable connection plate attached to the mold. The mold conduit connecting device consists of:

〔Example〕

Next, referring to FIGS. 1 to 4, one embodiment of the present invention will be explained by taking cooling water as an example. Reference numeral 11 denotes a die plate attached to a 12-karat metal mold, and a connection plate 13 is attached to the mold 12. The connection plate 13 is provided with a coupler 15 that corresponds to a coupler of the movable connection plate 14 to which a water supply or drainage hose (not shown) or the like is attached, and is designed to guide water as shown by arrow a. There is. The movable connecting plate 14 is connected to the tip of the piston rod 7 of the cylinder 16, which has a function of preventing falling due to its own weight, through a floating connector 18 that can be connected by absorbing all the misalignment in the three axial directions: vertical, horizontal, and front and back. It is installed. The cylinder 16 is fixed to an L-shaped bracket 19 attached to the die plate 11. A guide bar 2o has one end attached to the movable plate J4 via a floating connector 21, and the other end passes through the guide hole of the L-shaped bracket 19 to reach the connecting plate 22 and is fixed thereto. 23 is a guide pin. 24 is a coupler other than water, such as electricity.

[Effect]

The structure is as explained above, and the movable connecting plate can be freely adjusted via the 70-prong connector to match the connecting plate attached to the mold, ensuring a reliable connection. Became. Furthermore, in terms of operation, not only can a large number of connections be made, leading to a significant cost reduction, but also the coupling of the couplers is effortless and malfunctions do not occur, resulting in a longer service life.
