Problems solved by technology

However, the material hardness of the embedded part is usually less than that of the mold, so when the embedded part is placed in the mold, the appearance of the embedded part is often damaged due to the clamping of the mold during mold closing
[0003] Furthermore, due to the material characteristics between the embedded part and the mold cannot be tightly combined, it is also easy to cause troubles such as burrs on the appearance of the molded product after injection molding

Embodiment Construction

[0028] figure 1 is a partial sectional view of a mold according to an embodiment of the present invention. figure 2 Yes figure 1 Partial cross-sectional view of the mold in another state, where figure 1 It shows the state of a molded part that has not yet been injection molded in the mold, while figure 2 Then it shows the state of a molded part that has been injection molded in the mold. Please also refer to figure 1 and figure 2 , in this embodiment, the mold 100 is an embedded injection mold, which is used to carry an embedded part 200 and injection mold a molded part 300 on the embedded part 200 . In this embodiment, the embedding part 200 is, for example, an aluminum tube, and a rubber coating is formed on the embedding part 200 through the embedding and injection process, but the present invention is also applicable to other types of embedding. The injection process is not limited thereto.

[0029] The mold 100 includes a first mold base 110 , a second mold base...

Abstract

The invention discloses a doe, which is carried with an insert piece and protrusively molded with a molding piece on the insert piece, and is provided with buffers for preventing the insert piece from damaging when clamping the die. The die comprises a first die holder, a second die holder and a plurality of buffers. The first die holder is provided with a first pressing surface. The second die holder is movably assembled to the first die holder for enabling the first and the second die holders to open and close relative to each other. The second die holder is provided with a second pressing surface. The buffers are detachably arranged on the first and the second die holders respectively. When the first and the second die holders are mutually closed, part of the insert piece is positioned between the first and the second pressing surfaces, and the buffers are respectively abutted against the insert piece and the first pressing surface, and abutted against the insert piece and the second pressing surface.

Description

technical field [0001] The present invention relates to a mold, and more particularly to a mold capable of protecting embedded parts. Background technique [0002] Embedded forming dies are used in a wide range of fields in today's technology, and are especially suitable for combining two materials with different properties. However, the material hardness of the embedded part is usually lower than that of the mold. Therefore, when the embedded part is placed in the mold, the appearance of the embedded part is often damaged due to the clamping of the mold during mold closing. [0003] Furthermore, due to material properties between the embedded part and the mold, it is not possible to be tightly bonded, and it is also easy to cause troubles such as burrs on the appearance of the molded product after injection molding. Contents of the invention [0004] The present invention provides a mold with a buffer to protect embedded parts from being damaged due to mold clamping. ...
