Problems solved by technology
However, when the injection unit is separated from the main body of the injection molding machine as described above, the nozzle part for injecting resin will be exposed, so there is a possibility that high-temperature resin may scatter from the nozzle and cause a dangerous state if mishandled.
[0007] In addition, there is also the possibility of molding failure as follows: the specification of the injection molding machine connected to the injection unit does not correspond to multi-material molding; or if the specification of the injection unit screw diameter, maximum injection speed, maximum injection pressure, etc. If the clamping force of the injection molding machine, the size of the platen, the maximum injection speed, etc. are inconsistent, multi-material molding cannot be performed with the desired performance, etc.
[0008] The technology disclosed in Japanese Patent Application Laid-Open No. 2001-79877 and Japanese Patent Application Laid-Open No. 10-58479 discloses a technology in which an injection molding machine and an injection unit cooperate to be controlled by a single control device, but does not disclose the method of detecting the injection unit. The technique of linking the situation to act

Embodiment Construction
[0028] figure 1 It is a block diagram showing the structure of the injection unit 60 of this embodiment. The injection unit 60 is generally provided with only an injection device on the machine bed.
[0029] The injection device is mainly composed of a hopper 32 for storing resin, an injection cylinder 34 , a screw 36 arranged in the injection cylinder 34 , and a nozzle 38 arranged at the front end of the injection cylinder 34 . Also equipped with a ball screw 39, which is used to make the injection cylinder 34 and the nozzle 38 approach or separate figure 2 The injection molding machine 50 moves in the direction of an unillustrated metal mold. The resin stored in the hopper 32 is injected into the injection cylinder 34 . Then, the screw 36 is rotated by the rotation of the measuring motor M4, heated by a heater not shown, and the resin is conveyed toward the front end of the injection cylinder 34 while being melted. The pressure inside the injection cylinder 34 at this t...

The invention provides a multi-material molding machine performing multi-material molding, and when it is detected that an injection molding machine and an injection unit are not mechanically connected to each other, an operation of the injection unit is regulated. As a result, even if the injection unit is separated from an injection molding machine body, risk of a work in maintenance and repair works of the injection unit can be reduced.
Description
technical field [0001] The present invention relates to a multi-material molding machine, and more particularly relates to a multi-material molding machine equipped with an injection molding machine and an injection unit to perform multi-material molding. Background technique [0002] In an injection molding machine, in order to perform molding using two or more colors of materials or different materials, one injection molding machine is provided with a plurality of injection units, and these injection units perform injections sequentially. Two or more colors of materials and different materials are used to form an integral molded product. In such molding, a plurality of injection units are arranged around a mold, resins of different materials and colors are used in each injection unit, and these resins are injected into the mold to perform molding. [0003] The technique disclosed in JP-A-2001-79877 includes a general-purpose injection molding machine and an injection unit...
