Problems solved by technology

[0002] In traditional injection molds, the return spring is used as the push-out mechanism to push the molded product out of the mold; when it is working, when the injection head is moved away, the push-out mechanism pushes the product out immediately. Due to the continuous work of the mold, the cooling effect is reduced. Some products are pushed out before being cooled and formed, resulting in product deformation and low yield
Moreover, the traditional injection mold can only meet the injection molding of one size product. If other products are used, the injection mold will not be applicable, resulting in an increase in production costs.

Abstract

The invention discloses an automatic injection mold. The automatic injection mold comprises an upper mold and a lower mold, and is characterized in that a support plate is arranged between the upper mold and the lower mold; an automatic pushing mechanism, a guide column, a cavity and a surface needle plate are arranged in the lower mold; and the automatic pushing mechanism comprises a cylinder chamber, a pushing rod, a floating core body and a floating plate connected with each other. The automatic injection mold further comprises an infrared distance sensor and a temperature sensor. The automatic injection mold has the following beneficial effects: through arrangement of a cylinder and a cylinder linkage piece and cooperation with a sensor for use, after a mold is molded, the injection mold can automatically push the molded product outside, so that the production efficiency is greatly improved; and the distance sensor is adopted to adjust the distance of the core body moving in a molding cavity to adapt to injection molding products with different sizes so as to save the production cost.

Description

technical field [0001] The invention relates to the field of mold design, in particular to an automatic injection mold. Background technique [0002] In traditional injection molds, the return spring is used as the push-out mechanism to push the molded product out of the mold; when it is working, when the injection head is moved away, the push-out mechanism pushes the product out immediately. Due to the continuous work of the mold, the cooling effect is reduced. Some products are pushed out before being cooled and formed, resulting in product deformation and low yield. Moreover, the traditional injection mold can only meet the injection molding of one size product. If other products are replaced, the injection mold will not be suitable, resulting in an increase in production costs. Contents of the invention [0003] The purpose of the present invention is to provide an automatic injection mold for the deficiencies of the prior art. By setting the cylinder and the cylinder...
