Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mold temperature control devices face inefficiencies in switching between heating and cooling modes, leading to prolonged times for temperature stabilization due to temperature fluctuations and mixing of hot and cold water in temporal storage tanks, which delays the reaching of preset temperatures.
Innovation Solution
A mold temperature control device with a third medium supply portion and a control system that switches between medium supply modes to prevent direct temperature changes in the first medium supply portion, using a third medium to stabilize temperatures quickly and efficiently, and forcibly operating heat exchange means to ensure rapid temperature adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a temporal storage tank is used to store hot water and cold water alternately, then the switching between heating and cooling modes is enabled, but the hot and cold water mix in the temporal storage tank causing temperature fluctuations and delaying the reaching of preset temperatures
Solution Approach 1:
The invention divides the single temporal storage tank into two separate tanks: a first temporal storage tank for hot water and a second temporal storage tank for cold water. This segmentation prevents mixing of hot and cold water, allowing each tank to maintain its designated temperature and enabling faster switching between heating and cooling modes without temperature fluctuations.
Solution Approach 2:
The invention introduces a third medium supply portion that supplies third medium (corresponding to first medium) as an intermediary step during mode switching. This intermediary medium acts as a buffer, allowing the system to transition smoothly between heating and cooling modes by first supplying the corresponding medium type before switching to the target medium, thereby preventing direct temperature conflicts.
2Productivity
If cold water is supplied to replace hot water in the temporal storage tank, then the hot water is pushed out and returned to the hot water circulation path, but the cold water temperature rises and takes much time to cool down to preset temperature
Solution Approach 1:
The invention segments the storage system into separate first and second temporal storage tanks, where the first tank stores hot water and the second tank stores cold water. This prevents cold water from heating up by contact with hot water or return hot water, maintaining cold water temperature stability and reducing the time to reach preset temperature.
Solution Approach 2:
The invention extracts the problematic mixing function from the storage system by providing separate storage tanks for hot and cold water. The harmful thermal interaction is eliminated by physically separating the hot and cold water storage, allowing independent temperature maintenance in each tank.
3Productivity
If hot water is supplied to replace cold water in the temporal storage tank, then the cold water is pushed out and returned to the cold water circulation path, but the hot water temperature drops and takes much time to heat up to preset temperature
Solution Approach 1:
The invention segments the storage system into separate first and second temporal storage tanks, where the first tank stores hot water and the second tank stores cold water. This prevents hot water from cooling down by contact with cold water or return cold water, maintaining hot water temperature stability and reducing the time to reach preset temperature.
4Speed
If the switching between heating and cooling modes is performed directly without intermediary steps, then the response speed is fast, but the temperature fluctuations in the medium supply portion cause prolonged stabilization time
Solution Approach 1:
The invention performs preliminary action by supplying the third medium (corresponding to the target medium type) before switching to the target medium. For example, when switching from heating to cooling mode, the system first supplies third medium (hot water corresponding medium) to prepare the circulation path, then switches to second medium (cold water). This preliminary action prevents sudden temperature fluctuations and reduces stabilization time while maintaining fast switching speed.
Solution Approach 2:
The third medium supply portion acts as an intermediary during mode switching, providing a buffer medium that corresponds to the target medium type before the actual switch occurs. This intermediary step smooths the transition and prevents temperature shocks, allowing fast switching without prolonged stabilization periods.

AI summary
A mold temperature control device comprising a first medium supply portion for circularly supplying first medium to a medium flow path of a mold, a second medium supply portion for circularly supplying the medium flow path with second medium having temperature different from that of the first medium, and a third medium supply portion for circularly supplying third medium corresponding to the first medium to the medium flow path. The mold temperature control device further comprises a switching connection portion for switching between a medium supply path and a medium return path of each medium supply portion to connect the medium flow path, and a control portion which switches second medium supply mode circularly supplying the second medium to the medium supply path to third medium supply mode circularly supplying the third medium to the medium flow path, and to first medium supply mode supplying the first medium to the medium flow path by controlling the switching connection portion.
