Abstract

The invention provides a quick withdrawing mold. The quick withdrawing mold comprises a stepped shaft workpiece. The quick withdrawing mold further comprises a first mold body, a second mold body, a third mold body and a knocking mechanism which are sequentially connected. The first mold body, the second mold body and the third mold body are sequentially provided with a first mold cavity, a second mold cavity and a third mold cavity correspondingly. The second mold cavity and the third mold cavity communicate with each other and then are matched with the stepped shaft workpiece. The first mold cavity corresponds to the second mold cavity. The third mold cavity further comprises a knocking mechanism stretching hole, and the knocking portion of the knocking mechanism is located in the knocking mechanism stretching hole, corresponds to the third mold cavity and can knock the stepped shaft workpiece. A first spring is arranged in the second mold cavity and connected with a buffer plate. According to the quick withdrawing mold, the second mold cavity and the third mold cavity communicate with each other and then form a continuously-through mold cavity body, and pouring liquid is poured into the mold cavity body so that the stepped shaft workpiece can be formed. After the stepped shaft workpiece is formed and cooled, the right end of the stepped shaft workpiece is continuously knocked with the knocking mechanism, and accordingly the stepped shaft workpiece can be squeezed out of the left end of the second mold cavity quickly.

Description

technical field [0001] The invention relates to the field of molds, in particular to a quick draft mold. Background technique [0002] Industrial workpieces, especially trapezoidal shaft workpieces, are often formed by direct pouring of casting fluid through molds. However, after the workpiece is cooled, it is easy to stick to the mold directly, and it is inconvenient to pull out the mold. Contents of the invention [0003] The problem to be solved by the present invention is to provide a quick draft mold for convenient drafting in view of the above-mentioned deficiencies in the prior art. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a quick draft mold, including a stepped shaft workpiece, and also includes a first mold, a second mold, a third mold and a knocking mechanism connected in sequence; the first The mold, the second mold and the third mold have a first film cavity, a second film cavity and a third...
