Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail with reference to the drawings and the embodiments of the specification. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

On the contrary, the invention is intended to cover alternatives, modifications, equivalents and alternatives which may be included within the spirit and scope of the invention as defined by the appended claims. Furthermore, in order to provide a better understanding of the present invention to the public, certain specific details are set forth in the following detailed description of the invention. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details.

Referring to fig. 1-5, a PVD post-shaping tool for a metal injection molding product includes a driving member 1, a mold block 2, a mold plate 3, an extrusion block assembly 4, and an extrusion column assembly 5.

Specifically, driving piece 1 adopts the cylinder, and driving piece 1's output sets up upwards, and module 2 sets up above that, and template 3 sets up on module 2.

Specifically, the extrusion block assembly 4 comprises an extrusion block 401, a limiting block 402 and a reset elastic member 403; the number of the extrusion blocks 401 is two, and the two extrusion blocks 401 are arranged oppositely; the lower part of the extrusion block 401 is provided with a sliding block structure, the template 3 is provided with a sliding groove 302 matched with the sliding block structure, and the extrusion block 401 is arranged on the template 3 in a sliding manner through the matching structure between the sliding block structure and the sliding groove 302; the outer side of the extrusion block 401 is provided with an outer wedge surface. The limiting block 402 is positioned between the two extrusion blocks 401, plays a role in adjusting and shaping size, and is inserted into the template 3.
