Tri-plate injection die with changeable casting channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tri-plate injection dies require new male and female die cores for each product variation, leading to high equipment costs and space occupancy due to fixed casting channels that cannot adjust the injection point.
Innovation Solution
A tri-plate injection die design with changeable male and female die cores and a changeable casting channel die core, allowing users to easily swap and lock components onto existing die seats, enabling adjustment of the injection point by selecting different casting channel die cores.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed casting channel is provided on the fixed-side mounting plate by NC drilling, then the injection point is fixed and cannot be adjusted, but this requires opening new dies for each product variation leading to high equipment costs and space occupancy
Solution Approach 1:
The die is divided into separable components: a fixed-side die seat and a movable-side die seat that can be independently removed and replaced. The fixed-side die seat includes a fixed-side die plate with a fixed casting channel, while the movable-side die seat contains a movable-side die plate with a cavity. This segmentation allows users to keep the expensive fixed-side die seat and only replace the relatively inexpensive movable-side die seat when product variations occur, reducing overall equipment costs and storage space requirements.
2Adaptability or versatility
If new male and female die cores are manufactured for each product variation, then the injection point can be adjusted, but this increases equipment purchasing cost and occupies storage space
Solution Approach 1:
The fixed-side die seat is designed with universal applicability through its standardized structure and the use of standard fastening methods (screws or pins). The fixed-side die plate with its fixed casting channel serves as a universal base that can accommodate different movable-side die seats. This universality allows a single fixed-side die seat to support multiple product variations by simply changing the movable-side die seat, eliminating the need to store multiple complete die sets.
3Ease of manufacture
If the casting channel is fixed on the fixed-side mounting plate, then the structure is simple, but the injection point cannot be adjusted for different products
Solution Approach 1:
The die system transitions from a static fixed structure to a dynamic reconfigurable system. While the fixed-side die seat maintains a simple fixed casting channel structure, the movable-side die seat can be removed and replaced to adjust the injection point for different products. This dynamic capability allows the system to adapt to different manufacturing needs without complicating the basic structure of individual components.

AI summary
A tri-plate injection die with changeable male and female die cores, it has a movable-side die plate having therein a receiving space for changeably assembling in the space a male die core and a supporting plate, a movable-side mounting plate having two spaced blocks being respectively abutted on a junction between a supporting plate and the movable-side die plate to form contact areas to bear the injection pressure. And a fixed-side die plate with a receiving space for changeably assembling in the space a female die core and a changeable casting channel die core. The casting channel die core has therein a substituting casting channel that can change position deviation; thereby an injection point of hot molten plastics injected into the die can be changed in pursuance of the shape of the cavity of the female die core.
