Description
Technical field:
The utility model relates to mechanical equipment technical field, refers in particular to a kind of single-point needle valve hot runner mould.
Background technology:
Hot runner mould is a kind of injection molding mould at present commonly used, and it is with respect to the mould of cold runner structure, has to economize in raw materials, and can enhance productivity, and improves product quality, and it is many a bit to simplify product subsequent handling etc.Though hot runner mould has above-mentioned plurality of advantages, also there is certain deficiency in it.For example, common single-point needle valve hot runner mould mainly comprises a die main body, is positioned at the mouth body of die main body end and the needle-valve that is positioned at the die main body runner.This single-point needle valve mould is when work, at first, raw material will enter the runner die cavity by the injection moulding center that is positioned at the hot runner mould top, by moving up and down of control needle-valve, the melt plastic cement that control is positioned at runner is squeezed out by the mouth body, inject mold cavity by cast gate at last, be shaped to product.The deficiency of this structure maximum is exactly: at present in this series products, injection moulding center, needle-valve, cylinder center and cast gate center be not on same straight line, so cause needle-valve when moving up and down, the raw material that flows in the mould can produce horizontal force to the needle-valve of vertical motion, and this active force can influence the steady operation of line needle-valve.Simultaneously, because there is lateral flow in raw material, also, cause the not smooth of its operation to certain obstruction of the mobile generation of raw material.In addition, the deficiency that this product also exists is exactly: needle-valve is positioned at die main body inside, and the user can't intuitively recognize the situation of movement of needle-valve, at a time promptly, the user can't understand the present position of the needle-valve that is positioned at mould, so just brings certain trouble to the user.
The utility model content:
Technical problem to be solved in the utility model overcomes the shortcoming of present product exactly, provides a kind of operation more stable, and can directly observe the single-point needle valve hot runner mould of needle valve movement situation.
For solving the problems of the technologies described above, the utility model has adopted following technical scheme: the needle-valve that it comprises flow passage device, is arranged at the heater of flow passage device periphery and is positioned at flow passage device, wherein form the runner die cavity in the flow passage device, needle-valve is arranged in the described runner die cavity, be fixed with cylinder in described flow passage device periphery, needle-valve is positioned at cylinder axis, the cast gate center coincidence that is positioned at injection moulding center, cylinder or the oil cylinder center of flow passage device top and is positioned at the flow passage device below, in alignment.
After the utility model adopts said structure, at first injection moulding center, needle-valve axle center (being cylinder axis) and cast gate center are provided with point-blank, so just can reduce even eliminate the horizontal force of raw material, make the more stable of whole device operation needle-valve and mould inner wall.Simultaneously, the utility model adopts an annular cylinder to be placed in the periphery of flow passage device, needle-valve is connected the moving up and down of motion control needle-valve that so just can be by steam-cylinder piston by connecting shaft with steam-cylinder piston.Because steam-cylinder piston is installed in the utility model periphery, the user just can be directly by the motion that moves up and down the understanding needle-valve of piston.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is an internal structure cutaway view of the present utility model.
The specific embodiment:
See Fig. 1, the utility model is a kind of single-point needle valve hot runner mould, and it mainly comprises: flow passage device 1, the heater (scheming not shown) that is arranged at flow passage device 1 periphery and needle-valve (scheming not shown).Also be provided with a loam cake 7 above whole flow passage device 1, injection moulding is centered close to loam cake 7 tops.Wherein flow passage device 1 comprises top 11, runner body 12 and the hot mouth 13 that is positioned at runner body 12 ends.Form runner die cavity 10 in flow passage device 1, heater is positioned at this runner die cavity 10 peripheries.Raw material will 8 be entered in the runner die cavity 10 by entering the mouth by the injection moulding center, and the liquid charging stock of fusion will be entered in the formed product mould by cast gate by behind runner die cavity 10, the hot mouth 13 again.Needle-valve is arranged in the described runner die cavity 10, by the outflow of the liquid plastics in the needle-valve mobile control runner die cavity 10 from top to bottom.In above-mentioned, injection moulding center, needle-valve axle center (being cylinder or oil cylinder 2 centers) and cast gate center 5 coincidences that are positioned at flow passage device 1 top, in alignment.
One connecting shaft, 3 crosswise fixed are on piston 22, and needle-valve is connected in the middle of the connecting shaft 3.Offer the through hole that is used to install needle-valve on the connecting shaft 3, the through hole below is provided with the needle-valve cover 4 that is placed on the needle-valve.
Above-mentioned hot mouth 13 comprises hot mouth sharp-tongued 131 and the lining 132 that hot mouth sharp-tongued 131 is fixed in flow passage device 1 end.
When using the utility model, 8 enter in the runner die cavity 10 by entering the mouth with plastics through the injection moulding of high-temperature fusion, the outlet of hot mouth 13 simultaneously combines with the import of product mold die cavity.At first air flue 213 air inlets, another air flue 214 exhausts.Chamber 211 above gas enters promotes flange 221 and moves down, and promptly promotes whole piston 22 and moves down, and moves down thereby the connecting shaft 3 that drive and piston 22 are fixed reaches the needle-valve of fixing with connecting shaft 3.In like manner, behind the below that needle-valve moves, air flue 213 stops air inlet, another air flue 214 beginning air inlets, and air flue 213 exhausts so promote whole piston 22 upwards, even needle-valve moves upward.Needle-valve is controlled the liquid plastics in the runner die cavity 10 in the process that moves up and down, plastics are advanced in the mold cavity of product under pressure, finishes injection molding operation.
In sum, the utility model is provided with injection moulding center, needle-valve axle center (being cylinder 2 centers) and cast gate center 5 point-blank, so just can reduce even eliminate the horizontal force of raw material, make the more stable of whole device operation needle-valve and mould inner wall.Simultaneously, because the utility model adopts an annular cylinder 2 to be placed in the periphery of flow passage device 1, and is connected needle-valve by connecting shaft 3 with steam-cylinder piston 22, the moving up and down of motion control needle-valve that so just can be by steam-cylinder piston 22.Because steam-cylinder piston 22 is installed in the utility model periphery, the user just can be directly by the motion conditions of understanding needle-valve that moves up and down of piston 22, and so, the operator just can make things convenient for, in time understand the motion conditions of needle-valve.In addition, with respect to present like product, because the cylinders that adopt directly vertically drive needle-valve (cylinder and needle-valve are located along the same line) more in the product at present, so cause the longer of needle-valve palpus design, to be connected with the cylinder that is positioned at the outside, so just caused the injection moulding center to be positioned on the straight line, must enter in the runner again through behind one interconnection (to avoid cylinder) with needle-valve.This shows that the utility model also has the characteristics of simplifying product structure.
Certainly, the above only is example of the utility model, be not to limit the utility model practical range, all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
