Description

Muscle moulding accuracy controlling device in extrusion profile

Technical field

The utility model relates to the auxiliary field of plastic section bar extruding mould, relates in particular to the regulation device for muscle moulding in the correction die head on plastic section bar extruding mould.

Background technology

Extrusion molding mould is in extruding machine, material to be heated, pressurizeed, and makes it to become melt-flow state, then from mouth mould, it is extruded and moulding continuously. Interior muscle plays the vital effects such as sound insulation, heat insulation, insulation, energy-conservation, support, reinforcement in plastic material. As shown in Figure 1, in plastic irregular profile parison cools type-approval process, interior muscle is not contact with stock mould die cavity or cooling water, so the cooling of interior muscle can only carry out through the cross-ventilation in the heat conduction of interior muscle and section bar outer wall junction, section bar cavity and the heat radiation of interior muscle self, and finally all must carry out distribute heat by outer wall. Therefore in section bar, muscle is cooling wants slow more than outer wall. And interior muscle is in cooling procedure, except being subject to pining down of section bar outer wall type-approval process with section bar outer wall connecting portion, self is in without restrained condition. So interior muscle is leaving after die head, from viscous state through elastomeric state to the process of glass transition, be subject to the impact of gravity and produce distortion. And this distortion meeting is because material flows the fluctuation of the state of cooling in flow velocity and temperature and stock mould and is difficult to control in die head.

Utility model content

The technical problems to be solved in the utility model is that the Inner muscle form of extrusion profile is difficult to control generation distortion, and muscle moulding accuracy controlling device in a kind of extrusion profile is provided for this reason.

The technical solution of the utility model is: muscle moulding accuracy controlling device in extrusion profile, it comprises having machine neck, support spreader, rebound, support core, compressive plate, preformed board, profiled sheeting and the extrusion die body of inserting, it is characterized in that laterally offering on the support mould core & cavity of described support core the blowing groove extending to profiled sheeting, one side of described blowing groove is communicated with the air admission hole that is positioned at support core one side by gas hole, described air admission hole is connected with the air blowing adapter being communicated with extraneous source of the gas, the opposite side of described blowing groove stretches into respectively compressive plate, between Inner muscle feed chamber in preformed board and profiled sheeting, on described inserting, offer one end and be communicated with the air blowing chamber that the other end is in communication with the outside with blowing groove.

The improvement of such scheme is that described blowing groove upper surface is connected with silently groove.

The beneficial effects of the utility model are to be connected with air blowing adapter by external source of the gas, source of the gas reaches supporting plate by gas by air admission hole, compressive plate, blowing groove in preformed board, tiltedly cut air blowing chamber one at the input and output material end of inserting, insert and be connected with preformed board and be communicated with blowing groove, gas is discharged from the air blowing chamber of inserting, by regulating the atmospheric pressure amount of flow on interior muscle surface, thereby take away near the heat of the air of interior muscle, due to the physical principle of expanding with heat and contract with cold, interior influential point of tendons produces and tightens effect, and then muscle moulding in helping. This apparatus structure is simple, directly perceived, easy operating.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described further.

As shown in Fig. 2-6, the utility model comprises having machine neck 9, support spreader 10, rebound 11, support core 12, compressive plate 13, preformed board 14, profiled sheeting 15 and 7 the extrusion die body of inserting, on the support mould core & cavity 4 of described support core, laterally offer the blowing groove 2 extending to profiled sheeting, one side of described blowing groove is communicated with the air admission hole 5 that is positioned at support core one side by gas hole 1, described air admission hole is connected with the air blowing adapter 6 being communicated with extraneous source of the gas, the opposite side of described blowing groove stretches into respectively compressive plate, between Inner muscle feed chamber in preformed board and profiled sheeting, on described inserting, offer one end and be communicated with the air blowing chamber 8 that the other end is in communication with the outside with blowing groove.

The utility model is that air-control device is connected with air blowing adapter by external source of the gas, source of the gas is installed on die head outside, be easy to install, control, dismounting, source of the gas reaches gas hole by gas by air admission hole, reach compressive plate by gas hole by blowing groove again, between Inner muscle feed chamber in preformed board and profiled sheeting, can regulate the atmospheric pressure amount of flow on interior muscle surface, thereby take away near the heat of the air of interior muscle, gas with heat finally enters the external world by the air blowing chamber on inserting, in process of production, can see intuitively the situation of interior muscle, then by regulating the pressure knob on source of the gas, muscle atmospheric pressure around in regulating, make it to reach poised state. effectively control interior muscle moulding, thereby obtained desirable section bar.

For ensure gas in die head inside by operative constraint in blowing groove, blowing groove upper surface can be connected with silently groove 3, avoids hot gas to scatter in die head affecting mould normally working.
