Resin Molding Transfer Mechanism for Overhang-Clear Product Unloading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resin molding apparatuses face challenges in reliably collecting unnecessary resin while unloading resin molded products, particularly when the molded product has a resin sealing part on the lower side or when a release film is used, due to restricted space and suction pad deformation, leading to unstable resin collection.
Innovation Solution
A resin molding apparatus with a conveying mechanism that includes a first holder to lift and horizontally move the resin molded product under an overhang, a second holder to collect unnecessary resin, and mechanisms for lifting and horizontal movement, allowing the lower mold to be lowered and the plunger to be lifted, ensuring reliable collection of both products and resin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the distance between the overhang of the pot block and the mold surface of the lower mold is increased to allow horizontal movement of the resin molded product, then the resin molded product can be reliably unloaded, but the distance between the upper surface of the pot block and the lower surface of the upper mold becomes relatively small, restricting the size of the suction pad and reducing elastic deformation amount for collecting unnecessary resin
Solution Approach 1:
The invention introduces vertical movement dimension for the first holder to lift the resin molded product upward before horizontal movement. This dimensional change allows the product to clear the overhang obstacle without increasing horizontal distance, thereby preserving space for the suction pad in the second holder to collect unnecessary resin effectively.
Solution Approach 2:
The conveying mechanism is segmented into two independent holders: the first holder for resin molded product handling and the second holder for unnecessary resin collection. This segmentation allows each holder to be optimized independently - the first holder can move vertically to avoid the overhang while the second holder maintains sufficient space and size for effective suction pad deformation and resin collection.
2Device complexity
If the resin molded product is moved horizontally directly without vertical lifting, then the structure is simpler, but the resin molded product cannot clear the overhang or alignment pin and may be damaged or fail to unload
Solution Approach 1:
The invention adds vertical lifting movement to the conveying path, transforming a purely horizontal movement into a combined vertical-horizontal movement sequence. This dimensional addition enables the resin molded product to clear obstacles (overhang or alignment pin) without complicating the overall structure, as the vertical movement is achieved through a simple lifting mechanism integrated into the first holder.
3Ease of operation
If a release film is provided in the lower mold to facilitate separation, then the resin molded product can be separated from the mold surface, but reliable separation cannot be achieved solely by suction without additional movement mechanisms
Solution Approach 1:
The invention employs vertical lifting movement of the first holder to separate the resin molded product from the mold surface in the vertical dimension, complementing the release film's function. This vertical separation motion ensures reliable detachment even when the release film is present, overcoming the limitation of suction-only methods by adding a mechanical separation component in the vertical direction.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus effectively collects unnecessary resin and unloads resin molded products without collection failure, even with resin sealing parts or release films, by maintaining stable suction and avoiding contact with the overhang, thus preventing resin loss.
Implementation Method 1
The suction pad of the unnecessary resin suction part elastically deforms and contracts while being in contact with the unnecessary resin when the unnecessary resin is lifted
Implementation Method 2
each of the molded product suction part and the unnecessary resin suction part is formed of a suction pad made of resin

AI summary
A conveying mechanism includes a first holder that holds a resin molded product, a second holder that holds an unnecessary resin on the pot block, a first lifting movement mechanism that lifts the first holder such that the resin molded product moves upward under an overhang, and a horizontal movement mechanism that moves the first holder in a horizontal direction such that the resin molded product moves outward with respect to the overhang in a state where the first holder is lifted by the first lifting movement mechanism, a lower mold is lowered by a clamping mechanism, a plunger is lifted by a transfer mechanism, with respect to the lower mold in a state where the resin molded product is moved outward with respect to the overhang, and the second holder is in contact with the unnecessary resin on the pot block.
