A molding machine for extruding and preventing breakage of rigid foamed plastic particles

Abstract

The invention discloses a molding machine for extruding and preventing fracture of rigid foamed plastic particles. The structure includes a bottom box, a bottom control end, an auxiliary port, a forming extrusion hole, a processing box, and an introduction port. The bottom box is connected with the bottom control end , a processing box is installed on the top of the bottom control end. When the raw material is introduced through the import port, its return angle hook will be assisted by the rubber port, and the drag strip will move together. When the main rod is pulled, the curved strip will be stretched. force, so that the pocket ball can be smoothly unfolded along the size of the raw material. When the strip is moved and pulled, the elastic pocket layer will be squeezed, and its curved clip will give it a rebound force, so that the overlapping angle can still be smooth. The top of the top is in place, so that the size of the inside is not changed due to pulling. It can be initially fixed and output when the raw material is formed and extruded. After it is transported to the cooling liquid, the outer The objects fixed by the layer are pulled apart, which will not affect the cooling of the raw material molding, and can also ensure that it will not break.

Description

technical field [0001] The invention belongs to the field of equipment for producing plastic granules, and more specifically relates to a molding machine for extruding and preventing breakage of rigid foamed plastic granules. Background technique [0002] There are many types of plastic granules, among which there is a molding machine for extruding rigid foam granules to prevent breakage, which is foamed plastics. The foamed plastics are divided into three types: hard, medium and soft. Hard materials need It will only deform when it reaches a certain force, and the shape will not rebound after the external force is removed. When it is stirred with the required material, the strip will come out, thereby cooling the pelletizing equipment. [0003] Based on the above-mentioned inventor's discovery, existing plastic granule molding machines mainly have the following deficiencies, such as: [0004] When the rigid foam is extruded, half of the material will be in the cooling wate...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technology, when the rigid foam is extruded, after the cooling step, the material will be half in the cooling water and half in the extrusion barrel before the extrusion is finished. Because the material is relatively hard, this state is easy to cause molding The problem that the material is broken or even loosened
