Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for preheating tire curing press molds are inefficient, posing occupational safety risks and requiring significant manual effort due to the need to handle hot molds and dismantle tubing during the preheating process, which increases cycle time and energy consumption.
Innovation Solution
A method utilizing a receiving container and insulating hood positioned vertically, where the mold is preheated inside the container, with an automatic steam heating system and controlled pneumatic or hydraulic mechanisms to manage the insulating hood's movement, ensuring safe and efficient preheating without direct physical contact or unwanted heat radiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the mold is preheated outside the tire curing press using tubing connected to a superheated steam source, then the mold can be heated effectively, but the tubing must be dismantled from the hot mold and the mold is freely accessible causing occupational safety risks
Solution Approach 1:
The mold is placed inside a receiving container that is positioned within the tire curing press. The insulating hood is then lowered over the receiving container, creating a nested structure. This allows the mold to be heated by superheated steam while being protected within the press, eliminating the need for external tubing connections and preventing occupational safety risks associated with handling hot molds outside the press.
Solution Approach 2:
The receiving container acts as an intermediary between the superheated steam source and the mold. It provides a controlled environment for heating the mold with superheated steam while remaining inside the tire curing press, thus avoiding the need for external tubing connections and reducing occupational safety risks.
2Temperature
If the mold is preheated outside the tire curing press, then heating can be performed, but significant manual effort is required to handle hot molds and dismantle tubing
Solution Approach 1:
The mold is placed inside a receiving container that is positioned within the tire curing press. The insulating hood is then lowered over the receiving container, creating a nested structure. This allows the mold to be heated by superheated steam while being protected within the press, eliminating the need for external tubing connections and reducing occupational safety risks.
Solution Approach 2:
The system uses automatic coupling mechanisms that connect the superheated steam source to the receiving container automatically. The insulating hood is lowered and raised automatically, and the superheated steam is supplied automatically through controlled coupling, eliminating the need for manual handling of hot molds and tubing dismantling.
3Temperature
If traditional preheating methods are used outside the press, then the process can be performed, but the cycle time is significantly increased
Solution Approach 1:
The mold is preheated inside the tire curing press using superheated steam before the actual curing process begins. This preliminary heating action is performed while the mold is already in position within the press, eliminating the need for separate external preheating steps and reducing the overall cycle time.
Solution Approach 2:
The mold is placed inside a receiving container that is positioned within the tire curing press. The insulating hood is then lowered over the receiving container, creating a nested structure. This allows the mold to be heated by superheated steam while being protected within the press, eliminating the need for external tubing connections and reducing occupational safety risks.
4Temperature
If the mold is preheated outside the tire curing press, then heating can be achieved, but energy consumption increases due to unwanted heat radiation
Solution Approach 1:
The insulating hood, which could be seen as an additional component, actually converts the potential harm of heat loss to benefit by trapping and retaining the heat within the receiving container. The superheated steam heating is contained within the insulated environment, preventing heat radiation losses and improving energy efficiency.
Solution Approach 2:
The insulating hood provides a flexible or rigid insulating barrier that envelops the receiving container containing the mold. This insulation layer prevents unwanted heat radiation and heat loss to the surrounding environment, thereby reducing energy consumption while maintaining effective mold heating.

AI summary
The invention relates to a device for preheating at least one mould for a tyre heating press, which has a coupling for applying a heating medium to the mould. The mould to be heated is enclosed by a receiving container (19), which is secured within a framework and creates the coupling for the heating medium. The device helps to provide effective preheating of the mould by an insulating shroud (2), which is positioned over the receiving container (19) during the preheating process and reduces heat dissipation into the surroundings.
