Abstract
The utility model relates to preforming mold head which comprises an outer cavity body, a material storing cavity and an inner mold, wherein a material feeding interface and a material discharging interface are arranged on both ends of the outer cavity body; the material storing cavity is coaxially connected to the interior of the outer cavity body, and the open end faces to the material feeding interface of the outer cavity body; the center of the closed end of the material storing cavity is connected with the small diameter end of the inner mold, and a plurality of extrusion holes are arranged around the position where the closed end is connected with the inner mold. The inner mold is composed of a column-shaped forming main body and the small diameter end which is connected with one end of the column-shaped forming main body; an annular forming gap is formed between the circumferential surface of the forming main body and the inner side of the outer cavity; a heater is arranged in the inner mold. The utility model is connected between preforming molds of an outlet of a foaming device when used, the sectional material of a semi-finished product is firstly formed by the utility model, and then, a finished product is formed. The technology process is prolonged through the forming transition of the semi-finished product, the requirement of the technology precision directly from foaming technology to finished product forming is reduced and regular packaging products can be formed and produced.
Description
Technical field
The utility model relates to a kind of preformed die head, be mainly used in the gelatinization raw material (particularly being the dedicated set compound of primary raw material by grain) after the foaming of foam device output is carried out preformed, make the section bar of tubular or other shape, as the final finished semi-finished product raw material of (as through food containers, instrumentation package or industrial goods buffering package etc.).
Background technology
Utilize dedicated set compound Production and Packaging product or the new technology of grain for primary raw material at present, main preparation method is to utilize foam device that raw material is foamed, and the material that is foamed is chewed the mould molding of extruding supplying products from the injection of foaming cavity.Because the expanded material of foam device output is difficult to control and adjusting be connected (thermograde) of the temperature of mould, temperature has deviation will cause the moulding failure slightly.Also well do not address this problem at present.
Summary of the invention
The purpose of this utility model just provides a kind of preformed die head, to solve the foaming material shaped bad problem of employing that prior art exists.
The technical solution of the utility model is: comprise outer chamber, storage cavity and internal mold, the two ends of outer chamber are respectively equipped with charging interface and discharging interface; The two ends of storage cavity are respectively open end and blind end, this storage cavity is coaxial to be connected in the described outer chamber, and make its open end charging aperture of cavity outward, the central authorities of the blind end of described storage cavity are connected with the miner diameter end of internal mold, this blind end be connected with internal mold around be provided with a plurality of extrusion cavities; Described internal mold is made of with the described miner diameter end that is connected with the one end the forming body of cylindricality, leaves annular moulding gap between the side face of this forming body and the exocoel inboard; Be provided with heater in described internal mold inside.
Described charging interface and discharging interface are ring flange or gas thread.
The utility model is connected between the outlet preforming tool of foam device in use, is shaped to the semi-finished product section bar earlier by the utility model, and then is shaped to final products.Transition through the semi-finished product moulding has prolonged processing route, has reduced directly from the finished product moulding of foaming the requirement of craft precision, can the qualified packaging product of moulding output.
Description of drawings
Fig. 1 is the sectional structure schematic diagram of an embodiment of the utility model;
Fig. 2 is the sectional structure schematic diagram of another embodiment of the utility model.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model comprises outer chamber 1, storage cavity 5 and internal mold 2, and the two ends of outer chamber 1 are respectively equipped with charging interface 7 and discharging interface 6, can be ring flange 10 or gas thread 9.Described internal mold 2 is made of with the described miner diameter end that is connected with the one end the forming body of cylindricality.The two ends of storage cavity 5 are respectively open end and blind end, these storage cavity 5 coaxial being connected in the described outer chamber 1, and make the described open end charging interface 7 of cavity 1 outward.The central authorities of the blind end of storage cavity 5 are connected with the miner diameter end of internal mold 2 by bolt 8, are provided with a plurality of extrusion cavities 4 on every side what this blind end was connected with internal mold 2.Leave annular moulding gap 11 between the side face of the forming body of internal mold 2 and exocoel 1 inboard; Be provided with heater 3 in the inside of described internal mold 2.
The cavity of the storage cavity 5 of embodiment shown in Figure 1 and exocoel 1 are double-layer structure, and heat insulation effect is better.The cavity of the storage cavity 5 of embodiment shown in Figure 2 and exocoel 1 are with one deck structure, and be simple in structure.
The utility model connects the outlet of its charging interface 7 prefoam devices heater 3 energisings and is controlled at suitable temperature when using.The expanded material of being sent by foam device enters storage cavity 5, and is squeezed into the moulding gap 11 between the inboard of the side face of forming body of internal mold 2 and exocoel 1 from its extrusion cavities 4, and the discharging interface 6 from left end is sent to next molding procedure after the moulding in this gap.
Claims (2)
1, a kind of preformed die head is characterized in that: comprise outer chamber, storage cavity and internal mold, the two ends of outer chamber are respectively equipped with charging interface and discharging interface; The two ends of storage cavity are respectively open end and blind end, this storage cavity is coaxial to be connected in the described outer chamber, and make the described open end charging interface of cavity outward, the central authorities of the blind end of described storage cavity are connected with the miner diameter end of internal mold, this blind end be connected with internal mold around be provided with a plurality of extrusion cavities; Described internal mold is made of with the described miner diameter end that is connected with the one end the forming body of cylindricality, leaves annular moulding gap between the side face of this forming body and the exocoel inboard; Be provided with heater in described internal mold inside.
2, preformed die head according to claim 1 is characterized in that: described charging interface and discharging interface are ring flange or gas thread.
