Abstract

The invention provides a sprue bush demoulding and installing structure. The sprue bush demoulding and installing structure can simplify the installation of a sprue bush, and the installation can be implemented on the upper end surface of a sprue plate, so that the safety in the mould assembling process is improved. The sprue bush demoulding and installing structure comprises a sprue plate, a pad plate, a sprue bush, a plate A and a front mould, wherein a runner is formed inside the sprue bush; the runner penetrates through the plate A and the front mould; the upper part of the sprue bush is positioned inside an installing chamber of the sprue plate; a convergent structure at the lower part of the sprue bush is positioned inside a convergent installing chamber of the pad plate; the sprue bush demoulding and installing structure is characterized in that the pad plate is positioned inside a pad plate installing chamber of the plate A; the pad plate is supported on the front mould; an inclined guide slot which is inwardly convergent slantly from the top to the bottom is formed in each of the two sides of the pad plate; two inclined guide posts penetrate through the sprue plate and then are inserted into the corresponding inclined guide slots; cover plates are arranged on the upper parts of the inclined guide posts in a pressing manner; screws tightly fix the cover plates and the sprue plate from the top to the bottom.

Description

technical field [0001] The invention relates to the structural technical field of product molds, in particular to a sprue sleeve demoulding installation structure. Background technique [0002] In the demoulding structure of the existing sprue bushing, the backing plate of the sprue bushing is fastened to the sprue plate by screws. Since the installation of the screws requires additional holes and needs to be installed from bottom to top, it makes The installation of the mold is complicated, and it is prone to danger during the installation process. Contents of the invention [0003] The invention provides a sprue sleeve demoulding installation structure, which makes the sprue sleeve easy to install and can be completed on the upper end surface of the sprue plate, thereby improving the safety in the mold assembly process. [0004] A sprue sleeve demoulding installation structure, its technical scheme is as follows: ...
