Abstract

The invention relates to an injection machine with a two-stage vibrating mechanism and a head for an extruder, and comprises an extruder or an injection machine, a head left casing, a first heatproof and pressure-proof gasket, a second heatproof and pressure-proof gasket, a special-shaped flange and a head right casing. A conical diversion head is arranged on the left side of the center of the special-shaped flange; the injection machine and the head are characterized by further comprising a vertical ultrasonic vibrator, a vertical vibrating head, a third heatproof and pressure-proof gasket, a horizontal vibrating head and a horizontal ultrasonic vibrator; the horizontal ultrasonic vibrator is mounted at the center of the right side of the special-shaped flange; the horizontal vibrating head is arranged on the right side of the horizontal ultrasonic vibrator; a vertical step hole is further formed in the head right casing; the vertical ultrasonic vibrator is mounted on the vertical step hole; the vertical vibrating head is mounted below the vertical ultrasonic vibrator; a horizontal through hole is formed in the vertical vibrating head; the horizontal vibrating head penetrates through the horizontal through hole in the vertical vibrating head. The injection machine and the head have the advantages that the performances of a formed product can be effectively improved, so that the tensile strength and impact strength of the formed product are improved, the density becomes larger, the degree of crystallinity is improved, and both the internal quality and the appearance quality of the product are greatly improved.

Description

technical field

[0001] The invention belongs to the field of material processing and molding, such as the fields of material plasticization, mixing, injection and extrusion molding; in particular, it relates to an injection machine and an extruder with a two-stage vibration mechanism when materials are extruded and injected. Use the machine head. Background technique

[0002] Material injection and extrusion molding have the advantages of simple process, high production efficiency and precise product size, and can produce a large number of products with complex shapes in a short period of time, so they are widely used; The polymer pellets or powders are plasticized and melted into a polymer melt, and then the melt is injected into the die or cavity under high pressure and high speed for molding.

[0003] In order to improve the rheological properties of polymer melt and the structural properties of condensed matter during processing, some researchers introduced ultrasonic v...
