4results about How to "Realize automatic ejection" patented technology

This utility model provides an injection mold for an interchangeable insert-free automotive front grille, belonging to the field of mold technology. It includes a lower mold plate with two symmetrically arranged lower molding surfaces for forming a molding cavity. A multi-point injection mechanism is located directly above the lower mold plate, and several modular inserts are embedded in the lower mold plate. Bottom injection is achieved through a bottom-feed structure 8 on the modular inserts, reducing the impact of the gate on the product's surface quality. By embedding modular inserts in the lower mold plate and configuring a side ejection component for excess material, the traditional method of manually cleaning side excess material is changed, achieving automatic ejection of side excess material. The multi-point injection mechanism is correspondingly arranged with the modular inserts, working in conjunction with the symmetrical lower molding surfaces to form a molding cavity without insert seams, solving the surface defect problem caused by insert seams in traditional molds. Simultaneously, the modular design supports quick insert replacement, improving mold applicability.

This disclosure relates to the technical field of cold press machines. One embodiment of this disclosure provides a multi-layer wooden building formwork cold press machine, which includes: a base and a top frame. The top frame is disposed on the base. Hydraulic cylinders are disposed at the bottom of the top frame. A cold pressing plate is disposed at the output end of the hydraulic cylinders. A material unloading component is disposed in the base. An outer frame is disposed on the base. A cleaning component is disposed on the outer frame and the base. A pair of telescopic cylinders are disposed at both ends of the bottom of the base. The output end of the telescopic cylinders is connected to the bottom of the outer frame. The outer frame slides against the side surface of the base for a circumference. A groove is formed on the surface of the base, located directly below the outer frame. A collection groove is formed on the inner surface of the outer frame. The above technical solution solves the technical problem in the prior art where sawdust on the base gets embedded in the glue layer, causing unevenness on the surface of the board. In severe cases, this may cause poor adhesion, delamination, and other quality problems, affecting the flatness and structural strength of the multi-layer formwork.

The utility model relates to injection mold technical field discloses a kind of injection mold with automatic exhaust device, including bottom plate, the outside fixed connection of bottom plate has lower mould holder, the outside fixed connection of lower mould holder has multiple guide pillars, the outside fixed connection of guide pillar has upper mould holder, the bottom fixed connection of upper mould holder has mould core, the outside fixed connection of mould core has multiple positioning rods, the outside fixed connection of bottom plate has exhaust mechanism, the inside fixed connection of lower mould holder has driving mechanism;The exhaust mechanism includes mould cavity, the outside fixed connection of mould cavity is in the outside of lower mould holder. In the utility model, positioning rod is moved by mould core, so that servo plate drives tension spring to move, then vacuum pump drives suction pipe to move, so that injection mold realizes automatic exhaust, can accurately discharge cavity gas, and enhances production stability and intelligent level.
