Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a die interval adjustment device for a die casting machine, an injection molding machine, etc., which is capable of adjusting the gou interval according to the dimensions of the metal.

[Technical background of the invention and its problems]

In die casting machines, injection molding machines, etc., the fixed die is reciprocally supported by an anti-vibration ring, and the movable die, which is freely supported, is reciprocated by a movable gouer actuating mechanism that is adapted to a peel-off mechanism, thereby moving the fixed gold layer attached to the fixed die. It is designed to connect and separate from the moving metal attached to the die. therefore,
In this type of equipment, there is a limit to the range of movement of the movable die relative to the housing by the movable gouer actuating mechanism, so if the dimensions (thickness) of the mold change due to the molded product, the movable gouer actuating mechanism must be installed. It is necessary to displace the housing itself along the moving direction of the movable die, and to set the distance between the movable die and the fixed die in accordance with the size of the gold layer.

Therefore, in the past, the dimensions of all sections were measured, moved in a predetermined direction by a housing moving mechanism driven by an electric motor or hydraulic motor, and the amount of movement was visually confirmed using a scale attached to the Yakuji Pufferfish. was artificially manipulated to stop it.

Therefore, it is currently extremely difficult to stop the housing at a predetermined position, and the work has to be done over and over again, and the replacement and adjustment work of the metal lid is extremely troublesome, resulting in a decrease in work efficiency.

[Purpose of the invention]

The present invention has been made based on the above circumstances, and its purpose is to automatically set the die spacing commensurate with the dimensions of the mold by simply inputting the dimension information of the mold, etc., and to easily replace the mold. A die-casting machine that can improve workability such as adjustment.

It is an object of the present invention to provide a device for adjusting the goo spacing m in an injection molding machine or the like.

[Summary of the invention]

The present invention provides an input section for inputting gold dimension information, etc., a housing moving mechanism for moving the nozzle in a predetermined direction based on the input from the input section, and a movement amount detection means for detecting the amount of movement of the housing. , and a control means for stopping the moving operation of the housing moving mechanism when the moving amount detecting means detects that the housing has reached a predetermined position.

[Embodiments of the invention]

Hereinafter, the invention will be described with reference to an embodiment shown in the drawings.

FIG. 1 shows an injection molding machine. In the figure, reference numeral 1 denotes a pedestal, and a fixed die clamping plate 2 is provided at the right end of the upper surface of the pedestal 1. A movable die (mold clamping plate) 5 is provided on the left side of the fixed die 2 and is guided through a dieper 3.4 in a left-right direction, that is, in a direction toward and away from the fixed die 2, so as to be able to reciprocate. . The movable die 5 is configured to be reciprocated by a movable die actuating mechanism (1jJiwi mechanism) r attached to a housing 6 provided on the left end side of the upper surface of the pedestal 1. The moving die operating mechanism 1 has a structure in which a double toggle mechanism 9 is operated by a hydraulic cylinder 8, and the moving die 5 is reciprocated by the moving die operating mechanism 1, so that the movable die attached to the moving die 5 is moved. Fixed mold 11 attached to mold 10 and fixed die 2
and are in contact with and separating from each other.

Then, the movable metal 10 and the fixed metal mxi are brought into pressure contact state (mold clamped state), and the molten raw material injected from the nozzle 14 of the injection cylinder 13 is introduced into the molding chamber 12 formed at their mutually opposing surfaces. This makes it possible to obtain an injection molded product with a predetermined shape.

Moreover, the distance I between the fixed die 2 and the movable die 5 is determined by the dimension (
It is very easy to set the appropriate dimensions (thickness) to match the thickness.In other words, the moving die 5
The housing 6 to which the moving die actuating mechanism 7 is attached is reciprocally supported by the dieper 3.4, and has a female threaded member ( (not shown). Further, a driven gear 11 that meshes with a gear 16 driven by a drive source 15, such as an electric motor or a hydraulic motor, is fitted into the diper S, and constitutes a housing moving mechanism 1#.

On the other hand, in front of the fixed die 2, an input section (operation section) 20 of a preset device l#, which will be described later, is provided. As shown in FIG. 2, this input section 20 includes a numerical value setting section 21 for inputting dimension information of the gold. A display section 22 for displaying the numerical value set by the numerical value setting section 21, that is, dimensional information, and a setting completion button 23 for inputting that the setting of the dimensional information has been completed are provided, and these are controlled by the preset device 19. It is in a state where it is connected to a control unit 24 as a means.

Further, the control section 24 of the preset device 19 is connected to the housing 6
a movement amount detector (description will be omitted as it is publicly known) 25 as movement amount detection means for detecting the movement amount of using a linear detection method;
And it is connected to the drive source 15 of the housing moving mechanism 1g.

When the setting completion button 23 is pressed after inputting the dimensional information of the molds 10 and 11 attached to the dies 2 and 5 using the numerical value setting section 21 of the input section 20, the drive source 15 of the housing moving mechanism 18 is activated. , the dieper 3 in which the transfer screw portion 3a is formed is rotated in a predetermined direction, and when the mold size is small, the housing 6 moves forward (moves to the right in FIG. 1), and when the mold size is large, the housing 6 moves forward (moves to the right in FIG. 1). The housing 6 moves backward (moves to the left in FIG. 1). When the movement amount detector 25 detects that the housing 6 has reached a predetermined position commensurate with the mold size, the drive source 15 of the housing moving mechanism 18 is stopped.

As described above, according to the present invention, the fixed die 2 and the movable die 5 are automatically changed by simply inputting mold dimension information etc. from the input section 20.
The distance j can be set to an appropriate distance commensurate with the dimensions of the molds 10 and 11.

In the embodiment described above, the amount of movement of the housing 6 itself is detected using a linear detection method, but the present invention is not limited to this. The amount of movement of the housing σ may be detected by detecting the amount of rotation of the dial 10.

Further, although the injection molding machine has been described, it goes without saying that the present invention may also be employed in a die-casting machine.

In addition, it goes without saying that the present invention is not limited to the above-described embodiments, and that various modifications can be made without departing from the gist of the present invention.

〔Effect of the invention〕
