Embodiment Construction

[0022] Hereinafter, modes for implementing the present invention will be described with reference to the drawings. In each drawing, the same or corresponding symbols are attached to the same or corresponding structures to omit description.

[0023] (injection molding machine)

[0024] figure 1 It is a figure which shows the state at the end of mold opening of the injection molding machine of one embodiment. figure 2 It is a figure which shows the state at the time of mold clamping of the injection molding machine of one embodiment. Figure 1 ~ Figure 2 Among them, the X direction, the Y direction, and the Z direction are directions perpendicular to each other. The X direction and the Y direction represent the horizontal direction, and the Z direction represents the vertical direction. When the mold clamping device 100 is a horizontal type, the X direction is the mold opening and closing direction, and the Y direction is the width direction of the injection molding machine...

Abstract

The invention relates to an injection molding machine. The present invention addresses the problem of improving the ease of detachment of a cavity plate in a hot runner mold. An injection molding machine according to one embodiment of the present invention is provided with a cavity plate which includes a gate of a cavity space, a runner plate which includes a runner connected to the gate, a valvepin which closes the gate, the runner and the cavity space being cut off from each other or communicating with each other by the valve pin, a drive unit which drives the valve pin, a control unit which controls the drive unit, and an operation unit which performs an operation input for transmitting a command for opening the gate by the control unit, in which the operation unit includes a button, and the control unit continuously transmits a command for opening the gate if the button is pressed.

Description

technical field [0001] This application claims priority based on Japanese Patent Application No. 2018-070265 filed on March 30, 2018. The entire contents of this Japanese application are incorporated herein by reference. [0002] The invention relates to an injection molding machine. Background technique [0003] As an injection molding die, there is known a hot runner die in which only molded products can be taken out by controlling the heating of runners with a heater to keep the molding material in a fluidized state at all times. In the hot runner mold, a valve gate is set between the runner and the cavity. When the molding material is not filled, the valve pin is inserted into the gate to close the gate. When filling, the valve pin is retracted to open the gate. The valve pin or the cavity may be damaged due to contact or the like accompanying the operation of the valve gate, and therefore a technique for preventing such damage is disclosed (for example, refer to Paten...
