Abstract
Various examples provide a mold including a molding component and a supplementary component. The molding component may have a cavity, to enable a molten material to fill into the molding component to form an object. The supplementary component may include a bypass having a first opening located at a first position of the molding component and a second opening located at a second position of the molding component. The molten material may flow from the first position to the second position via the molding component, flow from the first opening to the second opening via the bypass and fill into the second position of the molding component through the second opening.
Claims15
A mold, comprising:
- a molding component having a cavity, to enable a molten material to fill into the molding component to form an object;
- and
- a supplementary component including a bypass having a first opening located at a first position of the molding component and a second opening located at a second position of the molding component;
- wherein the molten material flows from the first position to the second position via the molding component, flows from the first opening to the second opening via the bypass and fills into the second position of the molding component through the second opening.
A molding method, comprising:
- forming a mold including a molding component and a bypass, wherein the bypass has a first opening located at a first position of the molding component and a second opening located at a second position of the molding component;
- filling a molten material into the mold through an ingress of the mold, to enable the molten material to flow through the molding component from the first position to the second position, and enable the molten material to flow from the first opening to the second opening of the bypass and fill into the second position of the molding component via the second opening;
- hardening the molten material within the mold to get a model;
- and
- removing a redundant part corresponding to the bypass from the model to obtain an object.
A product, produced through a molding process comprising:
- forming a mold including a molding component and a bypass, wherein the bypass has a first opening located at a first position of the molding component and a second opening located at a second position of the molding component;
- injecting a molten material into the molding component to enable the molten material to flow through the molding component from the first position to the second position;
- diverting the molten material in the molding component into the bypass at the first position;
- guiding the molten material in the bypass component to fill into the second position of the molding component at the second position;
- separating a model from the mold after the molten material hardens;
- and
- disconnecting a redundant part corresponding to the bypass from the model to obtain the product.
