Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As Figure 1-Figure 2, a kind of material pressing device of large trigger, comprise and be provided with lamina rara externa 11, the plate face 1 of the large trigger of framework 12 and perforated inner layer plate 13 and driving mechanism, described lamina rara externa 11 is installed in the outside of framework 12, described perforated inner layer plate 13 is connected with inside framework 12 by guiding mechanism is mobilizable, described guiding mechanism comprises the guide rail 121 be arranged on inside framework 12 and the chute 131 be arranged on perforated inner layer plate 13 outward flange, described driving mechanism comprises motor 2, multiple reductor 3 and organize leading screw and nut mechanism more, described motor 2 drives multiple reductor 3 to rotate simultaneously, described each reductor 3 drives the screw mandrel 4 in one group of leading screw and nut mechanism to rotate, described perforated inner layer plate 13 is provided with nut 5, described screw mandrel 4 is connected by nut 5 with perforated inner layer plate 13 through lamina rara externa 11, described reductor 3 is installed on lamina rara externa 11, described lamina rara externa 11 upper screw rod 4 perforation place is provided with seal 6.
Seal 6, for being set in the logical cover of rubber on screw mandrel 4, guide rail 121 and chute 131 being equipped with sealing gasket, preventing the high temperature and high pressure gas entered in large trigger casing from overflowing, affect the making of evaporative pattern.
Reductor 3 at least arranges 3, and drive the screw mandrel 4 in three groups of leading screw and nut mechanisms to rotate, relative set three nuts 5 on described porous inner panel 13, three groups of screw mandrels 4 drive perforated inner layer plate 13 advance or retreat simultaneously, ensure that each position of perforated inner layer plate 13 is synchronized with the movement, make the better effects if that raw material compresses.
Motor 2 is connected with reductor 3 by chain drive.
Be provided with the large trigger of this material pressing device, because the stroke of material pressing device is adjustable, the thickness of the evaporative pattern cystosepiment produced accordingly is also just adjustable, the thickness of existing large trigger is generally 60 centimeters, and the stroke of material pressing device is generally 0-40 centimetre, the thickness of the evaporative pattern warming plate therefore produced is 20-60 centimetre, and a machine can produce the product of different size, practicality is better, and the product quality produced is better.
The course of work of this device is: during initial state, the distance of two perforated inner layer plates 13 on large trigger front face and rear plate face is in maximum rating, with spray gun, raw material is squeezed into after in large trigger, motor 2 drives reductor 3 to rotate, reductor 3 drives screw mandrel 4 to rotate, thus drive porous inner panel 13 rectilinear motion, namely reduce the distance between two perforated inner layer plates 13 on large trigger front face and rear plate face, perforated inner layer plate 13 pairs of raw materials compress, then high temperature and high pressure steam is passed into, lost foam forming, certain hour to be held, after lost foam forming completes, cooling, now motor 2 drives reductor 3 to rotate, reductor 3 drives screw mandrel 4 to reversely rotate, thus drive porous inner panel 13 to step back, then depanning, complete the making of evaporative pattern, in the process, perforated inner layer plate 14 is under the effect of guiding mechanism, synchronously, at the uniform velocity advance or retreat, evaporative pattern is compressed effective, even if evaporative pattern size is larger, also the problem of welding degree inequality can not be caused.
Material pressing device can be arranged on the front face of large trigger or the rear plate face of large trigger, and also can be that after header board, plate is all installed, this just requires that the front face of large trigger and rear plate face all comprise fixed outer layer, framework and movable perforated inner layer and could meet binder action.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
