The above and other aspects, features and advantages of the present disclosure will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.

Specific embodiments of the present disclosure are described hereinafter with reference to the accompanying drawings; however, it is to be understood that the disclosed embodiments are merely examples of the disclosure that may be embodied in various forms. Well-known and/or repeated functions and structures have not been described in detail so as not to obscure the present disclosure with unnecessary or unnecessary detail. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure in virtually any appropriately detailed structure.

The specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments in accordance with the disclosure.

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1, the embodiment of the utility model provides an injection mold, include:

a first mold 1 having a first convex portion;

the metal piece 2 is arranged around the first convex part and is correspondingly attached to the first convex part;

the second mold 5 is arranged opposite to the first mold 1 and used for enabling the first mold 1, the metal piece 2 and the second mold 5 to be matched to form an injection molding space, and the injection molding space forms an injection molding piece 3 after injection molding;

wherein, the second mould 5 is internally provided with a limiting component 4, and part of the limiting component 4 extends out of the second mould 5 and is propped against the metal piece 2 so as to limit the metal piece 2.

That is, the metal piece 2 is abutted and clamped by the limiting members 4 of the first mold 1 and the second mold 5, so that the metal piece 2 can be stable in position relative to the first mold 1 and the second mold 5, and the metal piece 2 is ensured not to be displaced in the injection molding process.

The utility model discloses can learn based on above-mentioned embodiment, the beneficial effect that the embodiment of the utility model possesses includes injection mold simple structure, easily preparation makes metalwork 2 can be at the in-process rigidity of moulding plastics through setting up stop component 4, avoids leading to corresponding slotted hole structure heterology that forms because of metalwork 2 shifts, and the emergence of the excessive gluey phenomenon when causing the later stage to this department injecting glue is showing the yields that has improved to mould, has improved the production efficiency who moulds the piece simultaneously.

Specifically, the metal material 2 in this embodiment is a copper ingot, and may be another metal ingot. The first convex part is a bump or a convex column, and is integrally formed with the first mold 1. The first convex part can be externally provided with a plurality of metal pieces 2 or sleeved with an annular metal piece 2, the specific structural form is indefinite, and the metal pieces can be replaced according to actual needs.

Further, as shown in fig. 1, the limiting member 4 in this embodiment is elastically arranged in the second mold 5, so that the limiting member 4 can move towards and away from the first mold 1 relative to the second mold 5, and when the limiting member 4 abuts against the metal part 2, the limiting member 4 can combine with the elastic force to apply the abutting force to the metal part 2 more stably, so as to limit the metal part 2.

With continued reference to fig. 1, in this embodiment, the second mold 5 is provided with a mounting groove, and the mounting groove is matched with the limiting member 4, so that the limiting member 4 can be movably disposed in the mounting groove and partially extend out of the mounting groove and the second mold 5. Specifically, one side that stop member 4 deviates from first mould 1 in this embodiment is equipped with a recess, is equipped with a spring 6 in this recess, and the both ends of spring 6 offset with the cell wall that the recess is relative with the mounting groove respectively, and promptly, spring 6 is spacing in the cavity that recess and mounting groove enclose, and stop member 4 realizes through this spring 6 with second mould 5's elastic connection. When the limiting component 4 abuts against the metal piece 2, the limiting component 4 extrudes the spring 6, and meanwhile, the spring 6 is subjected to the reverse force exerted by the second die 5, so that the limiting component 4 can continuously and stably exert extrusion force on the metal piece 2, and the relative position of the metal piece 2 is ensured to be fixed.

As shown in fig. 1, in this embodiment, a part of the limiting member 4 extends outward to form a top portion, and the top portion extends out of the second mold 5 and abuts against the metal piece 2. In this embodiment, at least two abutting portions are provided, or one abutting portion is provided and is annular. In practical application, the abutting portion may be extended outward from a part of the limiting member 4 to be in a cylindrical column shape, or in a needle shape, or in a conical column shape, and is not limited specifically as long as the abutting portion can stably abut against the metal piece 2.
