Abstract
The invention relates to an automobile acoustic component, in particular to a foaming mould exhaust mechanism of the automobile acoustic component, and belongs to the technical field of automobile interior trim part production equipment. The exhaust mechanism comprises an exhaust core, an air cylinder fixed seat and a pushing air cylinder. The air cylinder fixed seat is connected with the pushing air cylinder through internal threads, and a pushing shaft of the pushing air cylinder is connected with one end of the exhaust core through threads; the other end of the exhaust core penetrates the air cylinder fixed seat to stretch out, and the rear end of the pushing air cylinder is connected with a mould back cavity through external threads; and a plurality of evenly-distributed exhaust holes are formed in the air cylinder fixed seat in the circumferential direction, and are communicated with the exhaust core. The foaming mould exhaust mechanism is simple, compact and reasonable in structure, and a mould exhaust device can be converted into the mobile exhaust mechanism; and the mould exhaust problem can be solved, and cleaning, maintenance and overhauling after exhaust hole blockage are more convenient.
Description
Technical field
The present invention relates to a kind of acoustic part of automobile, a kind of acoustic part of automobile foaming mould exhaust gear, belongs to automotive upholstery production equipment technical field specifically.
Background technology
At present, the PU expanded material product such as sound insulating pad under automotive seat, carpet, in the extensive use of automotive upholstery field.This series products carries out formed product by the flowing of PU material, and exhaust quality directly determines product foaming quality, often makes a lot of exhaust pin at die face and carries out being vented in die cavity.For preventing foaming piece sticking to mould, need die face spraying releasing agent before the forming, after producing for a long time, many exhaust pins block, and cannot play exhaust effect, and steam vent are less, cannot dredge, often need mould to take apart and carry out replacing exhaust pin, bring a lot of inconvenience.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus a kind of acoustic part of automobile foaming mould exhaust gear is provided, guarantee that die venting puts in place, and facilitate the maintaining of late stage exhaust pin.
According to technical scheme provided by the invention, acoustic part of automobile foaming mould exhaust gear comprises exhaust core, cylinder holder and promotes cylinder, it is characterized in that: cylinder holder is connected by internal thread and promotes cylinder, the impeller-hub promoting cylinder is threaded connection one end of exhaust core, the other end of exhaust core stretches out through cylinder holder, promotes cylinder rear end and is connected in die back chamber by external screw thread; Described cylinder holder is along the circumferential direction provided with multiple equally distributed steam vent, and steam vent is communicated with exhaust core.
Further, being vented core is prism.
Further, promote cylinder front end and be provided with front inlet suction port, rear end is provided with rear inlet suction port.
Compared with the prior art the present invention has the following advantages:
Structure of the present invention is simple, compact, reasonable, Exhaust device of mold can be changed into movable exhaust gear, not only solve die venting problem, cleaning, maintaining and maintenance after more convenient steam vent blocking.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Inlet suction port after inlet suction port, 6-before description of reference numerals: 1-exhaust core, 2-cylinder holder, 3-promotion cylinder, 4-steam vent, 5-.
Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Figure 1, the present invention mainly comprises exhaust core 1, cylinder holder 2 and promotes cylinder 3, cylinder holder 2 is connected by internal thread and promotes cylinder 3, the impeller-hub promoting cylinder 3 is threaded connection one end of exhaust core 1, and the other end of exhaust core 1 stretches out through cylinder holder 2.Described promotion cylinder 3 rear end is connected to mould 1 by external screw thread and carries on the back in chamber.
Described cylinder holder 2 is along the circumferential direction provided with multiple equally distributed steam vent 4, and steam vent 4 is communicated with exhaust core 1, is exhausted by steam vent 4 and exhaust core 1 pair of dies cavity.
Described exhaust core 1 is prism, and exhaust gear installing hole corresponding on tool is circular hole, and exhaust gear is installed between the prism side of final vacuum core 1 and installing hole exists exhaust clearance, for exhaust.
Described promotion cylinder 3 front end is provided with front inlet suction port 5, rear end is provided with rear inlet suction port 6, during front inlet suction port 5 air inlet, the impeller-hub promoting cylinder 3 drives exhaust core 1 to get back in die body, during rear inlet suction port 6 air inlet, the impeller-hub promoting cylinder 3 drives exhaust core 1 to stretch out die body, is convenient to clear up the foreign material on exhaust core 1.
Operation principle of the present invention is: operationally, the gas in mold, by the steam vent on cylinder holder, then enters in exhaust core and discharges mold in the present invention.After steam vent blocking, inlet charge after cylinder, cylinder impeller-hub drives exhaust core to stretch out die body, clears up the foreign material on exhaust core.After exhaust core has been cleared up, the air inlet of cylinder nose air intake, cylinder impeller-hub drives exhaust core to reset, and completes the cleaning of foreign material on exhaust core.
Structure of the present invention is simple, compact, reasonable, Exhaust device of mold can be changed into movable exhaust gear, not only solve die venting problem, cleaning, maintaining and maintenance after more convenient steam vent blocking.
