AI Technical Summary
Technical Problem
Existing suction molds and hot-press forming molds result in insufficient strength of the local sidewalls of the finished paper-plastic cushioning parts, affecting the molding effect and causing them to fail drop tests.
Method used
A second suction hole and groove are added to the side wall of the forming groove of the suction mold to increase the suction volume of the side wall; the gap and draft angle of the hot pressing forming mold are adjusted to reduce the extrusion of the side wall slurry.
Benefits of technology
The sidewall strength of the finished paper-plastic cushioning parts has been improved to meet the drop test requirements and ensure the molding effect and flatness.

Abstract
The utility model provides a pulp suction mold and a paper-plastic buffer part injection molding device. A slurry suction mold comprises a mold main body, and a forming groove is formed in the surface of the mold main body; the first slurry suction hole is formed in the top surface of the forming groove; the second slurry suction hole is formed in the side wall of the forming groove, and the second slurry suction hole is communicated with the first slurry suction hole. The second slurry suction holes are additionally formed in the side wall of the forming groove of the slurry suction mold, so that the side wall of the forming groove can share more pressure when the slurry suction mold sucks slurry in a slurry pool and the bottom of the slurry pool exhausts air, and more slurry can be gathered on the side wall of the forming groove to form a local reinforcing area; therefore, the subsequent finished paper-plastic buffer piece is ensured to meet the drop test.
