Abstract
The invention discloses a gas control device in an inner cavity of an instrument panel foaming mould, which is formed by gas-filled gland strips which are distributed around the inner cavity of the whole instrument panel foaming mould to form a sealed ring, wherein gas-filled gland strips are divided into a plurality of sections, two ends of each section of the gas-filled gland strips are connected with an elbow respectively, and the elbows on the two ends are communicated with a gas pipe and an exhaust pipe respectively. The gas control device has a simple, precise and reliable structure, adjusts the waste gas discharge in the instrument panel foaming mould and achieves the sealing of foam materials through controlling the sequence of charging the gas-filled gland strips so that the foam materials are evenly distributed in the instrument panel foaming mould, thus the gas control device ensures that the foaming thickness of the product is even, plump, and bubble-free, and further ensures the quality of the product.
Description
Technical field
The present invention relates to a kind of gas control equipment of inner cavity of instrument board foaming mould, be specifically related to a kind of control device that can freely adjust each position gas filling volume of inner cavity of instrument board foaming mould.
Background technology
Employed in the market instrument board foaming mould, because the time of expanded material filling dies cavity exists successively, factors such as the dies cavity distribution of gas is inhomogeneous, or then occurring the moulding deficiency when mould molding leaks defectives such as material, thus influence the quality of product.
Summary of the invention
For solving the problems of the technologies described above, the gas control equipment of a kind of inner cavity of instrument board foaming mould provided by the invention, be distributed in the profile outside of whole instrument board foaming mould product by the gas-flow closure bar, forming a closed-loop constitutes, it is characterized in that: described gas-flow closure bar branch plurality of sections, the two ends of every section gas-flow closure bar are connecting bend respectively, and the elbow at described two ends is communicated with appendix and blast pipe respectively.
Described gas-flow closure bar is made of leather bag and built-in strengthening core.
The advantage of above structure is: the gas control equipment of described inner cavity of instrument board foaming mould is simple in structure, accurate, reliable, after expanded material enters inner cavity of instrument board foaming mould, by the priority of control to the gas-flow closure inflation, come the discharging of adjusting apparatus dash board foaming mould internal waste gas and realize sealing expanded material, thereby expanded material is evenly distributed at inner cavity of instrument board foaming mould, guarantee even, full, the no bubble of product foaming thickness, and then guaranteed the quality of product.In addition, in the gas-flow closure bar, increase strengthening core, make the gas-flow closure bar have certain rigid, not yielding, the stability of assurance product edge shape.
Description of drawings
Fig. 1 is the vertical view of embodiment of the present invention;
Fig. 2 is the partial enlarged drawing of gas-flow closure bar of the present invention;
Fig. 3 is the partial enlarged drawing of leather bag of the present invention.
The specific embodiment
The specific embodiment of the present invention is done the explanation in a nearly step below in conjunction with accompanying drawing.
As shown in Figure 1, 2, 3, around instrument board foaming mould 1, have groove 2, be embedded with some gas-flow closure bars 3 at groove 2.The two ends of described gas-flow closure bar 3 are connected with connecting bend 4,5 respectively, and elbow 4,5 is communicated with appendix 6 and blast pipe 7 sealings respectively, and appendix 6 and blast pipe 7 all are communicated with air compressor machine.In order to make gas-flow closure bar 3 except having good sealing, also possess certain rigid, with built-in strengthening core 10 in the leather bag 9 of gas-flow closure bar 3, like this, air bag 9 is difficult for can not influencing the quality of production of product edge part because of external force deformation when manufacturing a product.
During work, air compressor machine 8 is open-minded, gas-flow closure bar 3 is inflated by appendix 6 one by one according to the flow direction of the expanded material in the instrument board foaming mould 1, at expanded material when instrument board foaming mould 1 is filled, gas in the instrument board foaming mould 1 is discharged from the gas-flow closure bar 3 of unaerated, guaranteed that expanded material evenly distributes in instrument board foaming mould 1, filled in instrument board foaming mould 1 when expanded material to finish that gas-flow closure bar 3 also all is in inflated condition; When expanded material in instrument board foaming mould 1 after the moulding, blast pipe 7 is opened instrument board foaming mould 1 with the air scavenge in the gas-flow closure bar 3, expanded material gets final product removal.
Claims (2)
1, a kind of gas control equipment of inner cavity of instrument board foaming mould, be distributed in around the whole instrument board foaming mould die by the gas-flow closure bar, forming a closed-loop constitutes, it is characterized in that: described gas-flow closure bar branch plurality of sections, the two ends of every section gas-flow closure bar are connecting bend respectively, and the elbow at described two ends is communicated with appendix and blast pipe respectively.
2, the gas control equipment of a kind of inner cavity of instrument board foaming mould according to claim 1 is characterized in that: described gas-flow closure bar is made of built-in strengthening core in the leather bag.
