## Abstract

The present disclosure relates to a monobloc tool for the production of laminated molded parts. The tool includes an effective surface area facing the molded part to be laminated, a usable surface area facing a tool holder for securing the tool 1, at least one fluid duct 4 passing through without kinks and arranged in the interior near the face of the effective surface area, and at least one cavity arranged between the fluid duct and the usable surface area.

## Claims

### Claim 1

A monobloc tool for the production of laminated molded parts comprising:
an effective surface area facing a molded part to be laminated and a usable surface area facing a tool holder for securing the monobloc tool;
at least one fluid duct arranged in an interior of the monobloc tool near a surface at the effective surface area and passing through without kinks; and
at least one cavity arranged between the fluid duct and the usable surface area.

### Claim 2 (depends on 1)

The monobloc tool according to claim 1, wherein a distance of the fluid duct to the effective surface area is constant over an entire course of the fluid duct along the effective surface area.

### Claim 3 (depends on 1)

The monobloc tool according to either claim 1, wherein the monobloc tool a AlSi10Mg6 material.

### Claim 4 (depends on 1)

### Claim 14 (depends on 13)

The monobloc tool according to claim 13, wherein the fluid duct is guided directly downstream of the inlet port in a direction approximately perpendicular to the effective surface area, then parallel to the effective surface area, and finally approximately perpendicular to the effective surface area as the fluid duct extends to the outlet port.

### Claim 15 (depends on 1)

The monobloc tool according to claim 1 further comprising a plurality of fluid ducts are arranged adjacent one another.

### Claim 16 (depends on 15)

The monobloc tool according to claim 15, wherein the plurality of fluid ducts have a common inlet port and a common outlet port.

### Claim 17 (depends on 15)
