EPP forming machine

Abstract

The invention relates to the technical field of accessory devices of EPP machining equipment, in particular to an EPP forming machine. Two working stations are arranged on a convex die for forming anddischarging simultaneously and the discharging working station is outside the molding working station to reduce potential safety hazards. Meanwhile, an auxiliary device is arranged on a concave die to reduce the difficulty of disassembling the EPP product in an extrusion cavity of the concave die. The EPP forming machine comprises a molding device, the concave die and the convex die, and the inside of the concave die is provided with the extrusion cavity; and the EPP forming machine also comprises a lifting bar, a pressing spring and a driving plate. A telescopic cavity is formed in the top region of the concave die. The EPP forming machine further comprises two sets of threaded rods, two sets of adjusting rings and two sets of annular blocks, wherein the top region and the bottom regionof the convex die are separately provided with two sets of pushing cavities. The EPP forming machine further includes four sets of cylinders, four sets of draft angles, four sets of fixed rings, foursets of upper mounting rods and four sets of lower mounting rods. The four sets of cylinders are provided with four sets of push shafts and four sets of fixed columns.

Description

technical field [0001] The invention relates to the technical field of EPP processing equipment attachments, in particular to an EPP forming machine. Background technique [0002] As we all know, EPP material has the advantages of light specific gravity, good elasticity, shock resistance and compression resistance, high deformation recovery rate, good absorption performance, oil resistance, acid resistance, alkali resistance, resistance to various chemical solvents, non-absorbent, insulation, heat resistance, non-toxic and tasteless, etc. , At the same time, it can be 100% recycled with almost no reduction in performance. EPP material is a real environmentally friendly foam plastic, so EPP material is widely used in automobiles, such as bumper core materials, anti-collision blocks and roof linings. , as well as door filling, headrests and sun visors, etc. EPP materials save fuel consumption for cars and improve the safety factor of passengers. Among them, the EPP molding mac...

Problems solved by technology

[0003] In the use of the existing epp molding machine, it is found that when the finished product is separated from the concave and convex molds, the concave and convex molds need to be separated by a large distance for the convenience of the staff. It is inconvenient to take out from the side, especially for some large workpieces, which makes it more difficult to unload. Another unloading method is to raise the molding machine, and after the staff separates the cost from the concave and convex molds, the finished product falls from the bottom, but still needs The staff drilled between the concave and convex dies of the molding machine to operate, which increased the danger

On the other hand, both of these two blanking methods will take a long time and reduce production efficiency;

[0004] At the same time, the existing molding equipment has poor control ability to the filling amount of the raw material in the extrusion cavity of the die, and the situation that the raw material in the extrusion cavity of the die is not filled will cause the EPP finished product to not be formed, thereby As a result, the use limitations are high; and it is difficult to control the depth of the extrusion plate of the punch into the extrusion cavity of the die through the hydraulic cylinder, which makes the precision of the molding equipment processed into EPP finished products poor, resulting in practicality Poor; it is more difficult to remove the EPP finished product from the extrusion cavity of the die, resulting in poor convenience of use
