Abstract

An injection molding machine for a composite molded product is an injection molding machine for a composite molded product, in which an injection device or a rotary table is arrayed with a movable platen attached with a movable metal mold and the injection device or the rotary table is driven using an electric motor, wherein, at any position below, side, or rear of the movable platen, a plurality of cableveyors, and which house cables, and connected to the movable metal mold or the movable platen or connected to the injection device in addition to the movable metal mold or the movable platen is disposed in parallel to one another so that longitudinal directions of the cableveyors coincide with a mold opening/closing direction A of the movable platen.

First claim

What is claimed is:

1. An injection molding machine for a composite molded product, in which an injection device or a rotary table is arrayed with a movable platen attached with a movable metal mold and the injection device or the rotary table is driven using an electric motor,
wherein, at any position below, side, or rear of the movable platen,
three or more cable carrying-and-guiding devices are provided for carrying and guiding cables, wherein each cable carrying-and-guiding device includes a structure formed of two side band portions in each of which respective link portions are coupled to one another, and an arm portion that couples the two side portions to each other, wherein the structure of the cable carrying-and-guiding device defines a space for housing cables,
wherein the three or more cable carrying-and-guiding devices are configured to house cables connected to the movable metal mold or the movable platen or connected to the injection device in addition to the movable metal mold or the movable platen;
wherein the three or more cable carrying and guiding devices are disposed in parallel to one another so that longitudinal directions of the cable carrying-and-guiding devices coincide with a mold opening/closing direction of the movable platen;
wherein the three or more cable carrying-and-guiding devices are located at different positions in a direction from an operation side to a non-operation side of the injection molding machine;
wherein each of the three or more cable carrying-and-guiding devices includes a fixed end and a moving end located upward relative to the respective fixed end,
wherein each fixed end is fixed to a bed or a bed side member of the injection molding machine,
wherein the moving end is fixed to the movable platen or a structural member connected to the movable platen.

2. The injection molding machine for a composite molded product according to claim 1 , wherein at least an electrical cable, a hydraulic oil cable and a temperature control medium cable are housed in the three or more cable carrying-and-guiding devices, and
at least the electrical cable and the temperature control medium cable are housed in different cable carrying-and-guiding devices.

3. The injection molding machine for a composite molded product according to claim 2 , wherein a first cable carrying-and-guiding device that houses the electrical cable, a second cable carrying-and-guiding device that houses the hydraulic oil cable, and a third cable carrying-and-guiding device that houses the temperature control medium cable are individually provided.

4. The injection molding machine for a composite molded product according to claim 1 , wherein an intermediate metal mold that rotates about an axis in a direction perpendicular to a mold opening/closing direction is provided between a stationary platen attached with a stationary metal mold and the movable platen attached with the movable metal mold,
a first injection device is provided on one side of the stationary platen,
a second injection device is provided on rear of the movable platen to be movable together with the movable platen; and
wherein a fourth cable carrying-and-guiding device is connected to the second injection device.

5. The injection molding machine for a composite molded product according to claim 2 , wherein an intermediate metal mold that rotates about an axis in the direction perpendicular to the mold opening/closing direction is provided between a stationary platen attached with a stationary metal mold and the movable platen attached with the movable metal mold,
a first injection device is provided on one side of the stationary platen, and
a second injection device is provided on rear of the movable plate to be movable together with the movable platen; and
wherein a fourth cable carrying-and-guiding device is connected to the second injection device.

6. The injection molding machine for a composite molded product according to claim 3 , wherein an intermediate metal mold that rotates about an axis in the direction perpendicular to the mold opening/closing direction is provided between a stationary platen attached with a stationary metal mold and the movable platen attached with the movable metal mold,
a first injection device is provided on one side of the stationary platen, and
a second injection device is provided on rear of the movable plate to be movable together with the movable platen; and
wherein a fourth cable carrying-and-guiding device is connected to the second injection device.

7. The injection molding machine for a composite molded product according to claim 1 , wherein the rotary table attached with the movable metal mold is attached to the movable platen to be rotatable by the electric motor, and
the movable metal mold or the movable platen is attached with a hydraulic cylinder.

8. The injection molding machine for a composite molded product according to claim 2 , wherein the rotary table attached with the movable metal mold is attached to the movable platen to be rotatable by an electric motor, and
the movable metal mold or the movable platen is attached with a hydraulic cylinder.

9. The injection molding machine for a composite molded product according to claim 3 , wherein the rotary table attached with the movable metal mold is attached to the movable platen to be rotatable by the electric motor, and
the movable metal mold or the movable platen is attached with a hydraulic cylinder.

10. The injection molding machine for a composite molded product according to claim 1 , wherein the three or more cable carrying-and-guiding devices includes at least one cable chain.

11. The injection molding machine for a composite molded product according to claim 1 , wherein the three or more cable carrying-and-guiding devices includes at least one device that carries and guides cables or hoses.

12. The injection molding machine for a composite molded product according to claim 1 , wherein the three or more cable carrying-and-guiding devices includes at least one cable protection chain.

13. The injection molding machine for a composite molded product according to claim 1 , wherein opening portions are provided in the fixed ends and the moving ends of the three or more cable carrying-and-guiding devices.
