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.

The utility model relates to the technical field of alloy contacts, and discloses an integrated forging press for alloy contact processing, which comprises a base, a fixing frame is fixedly arranged on the top surface of the base, a forging assembly is fixedly mounted at the upper end of the fixing frame, a lower die is arranged right below the forging assembly, a connecting mechanism is arranged below the lower die, and the connecting mechanism is connected with the fixing frame. A discharging mechanism is arranged on the outer side of the lower mold, the connecting mechanism comprises an ejection part and a driving part, and the discharging mechanism comprises a discharging part and a cooling part. The rotating plate is driven by the motor to rotate, then the lifting plate and the ejector rod are pushed to move upwards, automatic ejection of the alloy contact is achieved, manual intervention is reduced, workers are prevented from being hurt when the alloy contact is discharged, the positioning rod slides in the positioning sleeve and is matched with compression and rebound of the spring, stability of the ejection process is ensured, and production efficiency is improved. The alloy contact is protected from being damaged in the ejection process, and the service life of equipment is prolonged.

The utility model belongs to the field of steel structure bending devices, and particularly relates to a bending device for steel structure production, which comprises a base plate, a transmission mechanism is arranged on one side of the base plate, an extrusion component is arranged on one side of the transmission mechanism, a forming component is arranged on one side of the extrusion component, and an ejection component is arranged on one side of the forming component. Through the ejection assembly, the steel structure can push the ejection rod to descend along the U-shaped frame and stretch the first spring in the bending forming process, the position of the ejection rod is reinforced through the limiting plate, and when the ejection rod descends to a certain position, the resistance increasing pad is attached to the clamping groove, so that certain friction force exists between the ejection rod and the U-shaped frame; after the steel structure is bent and formed, the extrusion assembly firstly resets, due to the fact that the resistance increasing pad is attached to the clamping groove, the first spring rebounds to slowly pull the ejector rod to reset, and when the resistance increasing pad is not in contact with the clamping groove, the ejector rod rapidly pops up and resets to eject out the bent steel structure.

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.
