Description
Technical Field
The utility model belongs to the field of casting molds, and particularly relates to a casting mold for efficient forming.
Background
Casting is a hot metal working process in which liquid metal is cast into a casting cavity that conforms to the shape of a part, after it is cooled and solidified, to obtain a part or blank. The casting substance is mostly metal which is originally solid but is heated to liquid state, and the material of the die cavity can be sand, metal or even ceramic. The method used may be different according to different requirements.
In existing industrial casting molds, particularly those involving earphone housings, the feed channel typically communicates with the sides of the mold cavity. During with liquid metal during the casting follow the feed inlet injection die cavity of die cavity side through feedstock channel, liquid metal always flows to around from feed inlet one side, and the condition that the filling state of the one side that is close to the feed inlet in the die cavity and one side that keeps away from the feed inlet is different when liquid metal spills over from the discharge gate like this can appear, and the position of keeping away from the feed inlet can also appear the cavity even when liquid metal spills over from the discharge gate, so leads to the defective percentage of cast product higher.
Disclosure of Invention
In order to solve the problems, the utility model aims to provide a casting mold for high-efficiency forming, which solves the problem that the defect rate of cast products is high due to the phenomenon of uneven filling caused by the liquid metal flowing from one side of a feeding hole to the periphery.
Another object of the present invention is to provide a casting mold with high molding efficiency, simple structure and easy mass production.
In order to achieve the purpose, the technical scheme of the utility model is as follows:
the utility model provides a casting die for efficient forming, which comprises a feeding disc, a feeding channel, a feeding port and a die cavity, wherein the feeding disc, the feeding channel, the feeding port and the die cavity are sequentially communicated, the feeding disc and the feeding channel are arranged above the die cavity, and the feeding port is arranged in the center of the top of the die cavity. The feeding channel is communicated with the die cavity through the feeding hole. The liquid metal enters the feeding channel from the feeding disc, then enters the feeding hole from the feeding channel, and then enters the die cavity from the center of the top of the die cavity through the feeding hole. The distances from the feed inlet to all points on the side of the inner part of the die cavity are equal, so that the liquid metal flows uniformly from the center to the periphery in the die cavity, the liquid metal is uniformly distributed on the side of the die cavity, the die cavity is filled fully when the liquid metal overflows from the discharge outlet, and the defective rate of cast products is reduced.
Furthermore, the die cavity comprises two symmetrically arranged die cavities, the feeding channel comprises a main material channel and two branch material channels, the two branch material channels are symmetrically arranged, the main material channel is communicated with the branch material channels, and each branch material channel is communicated with the die cavity through a feeding hole. The two die cavities and the two material supporting channels are arranged, so that liquid metal is fed from the center of the top of the die cavities respectively, two molds are cast at one time under the condition that the die cavities are fully filled with the liquid metal, the casting efficiency is improved, and the casting cost is reduced. The traditional casting mould is fed from the side of the mould cavity, if two mould cavities are arranged, although two mould cavities can be simultaneously cast, the two mould cavities can not be filled with liquid metal fully and firmly at the same time through the side feeding, and the defective rate of the cast mould products is higher.
Further, a plurality of die holes are formed in the two die cavities. The user confirms the concrete parameters such as quantity, size, shape of nib according to actual casting demand, sets up the nib that matches with the casting demand on the die cavity, realizes casting the metal casting that has the surface arch through this casting mould one-step in place. Compared with a casting tool which only can cast a main body shape with a smooth surface and needs to form a bulge and be additionally processed, the casting tool is time-saving, labor-saving and cost-saving.
Furthermore, the feed inlet is trumpet-shaped and gradually enlarged from top to bottom. And the gradually increasing shape of the feeding hole from top to bottom is convenient for liquid metal to flow into the die cavity communicated with the feeding hole more smoothly in the casting process.
Furthermore, the bottom end of the feeding hole is fixedly connected with a flow guide port, the inner wall of the flow guide port is uniformly and upwardly protruded at intervals to form a plurality of flow guide channels, each flow guide channel is connected with the center of the flow guide port and the side of the flow guide port, and the flow guide port is communicated with the center of the top of the feeding hole and the center of the die cavity. In the casting process, liquid metal flows from the feed inlet to the center of the diversion port and then flows to the side of the diversion port along the diversion channel. The distances between the side of each flow guide opening and the side of the die cavity are equal and shorter, so that the liquid metal is uniformly distributed on the side of the die cavity, the die cavity is filled fully when the liquid metal overflows from the discharge hole, the phenomenon of uneven filling is avoided, and the defective rate of cast products is reduced.
The utility model has the advantages that: compared with the prior art, in the utility model, the distances from the feed inlet to each point on the side of the inner part of the die cavity are equal, so that the liquid metal flows uniformly from the center to the periphery in the die cavity, the liquid metal is distributed uniformly on the side of the die cavity, the die cavity is filled fully when the liquid metal overflows from the discharge hole, the phenomenon of non-uniform filling is avoided, and the defective rate of cast products is reduced.
