Abstract

The utility model provides a structure improving device of a stock mould, which is composed of a water/vapour separation dry type stock mould, an integral vacuum negative-pressure grid plate positioning chamber, an eddy current type water tank, an upper adjusting handle, a lower adjusting handle, a left adjusting handle, a right adjusting handle, a vacuum meter, a vacuum pump, a suction pump, and a water tank. Compared with the prior stock mould, the structure improving device of the stock mould has the advantages that the realization is convenient, the manufacturing is simple, the replacement and the assembly of the mould are convenient, the positioning is precise, both water and air are pumped, the cleaning and the maintenance are convenient, the production efficiency is high, and the service life is long.

Description

A kind of improvement constructional device of stock mould

Technical field

The utility model relates to a kind of stock mould of plastic extruding forming, especially a kind of improvement constructional device of stock mould.

Technical background

At present, in high speed development energy technology, information technology, material technology has also obtained developing rapidly. on the existing plastic extruding forming stock mould, what adopt mostly is dried stock mould, this dried stock mould is made complicated, and very high in the required precision, difficulty in the cleaning maintenance is used also inconvenient; Particularly the water route maintenance needs the very technology of specialty, simultaneously, because the water route cleaning is bad, causes the production efficiency of mould to descend gradually, thereby has shortened the life-span of mould.The installation adjustment of each die change aborning, steam connects also very bothersome, because of plug is many, causes very inconvenience.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and provide a kind of improvement constructional device of stock mould, can realize conveniently, make simple, die change is easy for installation, easy maintenance is taken out, cleared up in accurate positioning, steam altogether, production efficiency height, life-span are long.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of improvement constructional device of stock mould comprises: steam separates dry type typing, monoblock type negative pressure of vacuum screen orientation room, eddy current type water tank, upper and lower adjusting handle, left and right adjusting handle, vacuum meter, vavuum pump, suction pump, water tank composition.The viscoplasticity parison of extruding by die head, enter in the die cavity of negative pressure of vacuum orientation room, enter screen formula preform section then, forming negative pressure by the steam passage between screen makes parison be adjacent to die cavity, the coolant guiding channel cooling parison that forms between screen, realize that surface gelling enters the floating type screen typing stage again, monoblock type negative pressure of vacuum screen orientation room provides negative pressure, the slit that forms between screen constitutes the vacuum steam passage, make parison continue to be adjacent to the mould rifle, medium channel hole and passage make cooling medium flow on the section bar surface and take away the parison cools moulding, make the further cooling and shaping of parison, quicken the typing of gelation parison again, enter the eddy current water tank and make the moulding of the whole further cooling of section bar fixed dimension.

The beneficial effects of the utility model are:

1, floating type screen is close to equal gap structure and can the Automatic Extraction screen be convenient to mold cleaning and safeguards;

2, cooling medium directly contacts section bar, the cooling effectiveness height, and surface quality is good;

3, open type steam line structure, water channel, steam passage Maintenance free;

4, the fixing mould bases of normal formula screen is convenient to the die change effect;

5, automatic capturing in the floating structure traction, the mould resistance is little, section bar linearity height.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model

Fig. 2 is the vertical view among Fig. 1

Among the figure, 1, upper and lower adjusting handle, 2, left and right adjusting handle, 3, vacuum meter, 4, vavuum pump, 5, suction pump, 6, water tank, 7, steam separates the dry type typing, 8, monoblock type negative pressure of vacuum screen orientation room, 9, the eddy current type water tank.

The specific embodiment

As shown in the figure, a kind of improvement constructional device of stock mould comprises: upper and lower adjusting handle (1), and left and right adjusting handle (2), vacuum meter (3), vavuum pump (4), suction pump (5), water tank (6) is formed; The viscoplasticity parison of extruding by die head, separating dry type typing (7) by steam enters in the die cavity of negative pressure of vacuum orientation room (8), enter screen formula preform section then, forming negative pressure by the steam passage between screen makes parison be adjacent to die cavity, the coolant guiding channel cooling parison that forms between screen, realize that surface gelling enters the floating type screen typing stage again, monoblock type negative pressure of vacuum screen orientation room provides negative pressure, the slit that forms between screen constitutes the vacuum steam passage, make parison continue to be adjacent to the mould rifle, medium channel hole and passage make cooling medium flow on the section bar surface and take away the parison cools moulding, make the further cooling and shaping of parison, quicken the typing of gelation parison again, enter eddy current type water tank (9) and make the moulding of the whole further cooling of section bar fixed dimension.

Claims

1, a kind of improvement constructional device of stock mould comprises: upper and lower adjusting handle (1), and left and right adjusting handle (2), vacuum meter (3), vavuum pump (4), suction pump (5), water tank (6) is formed; It is characterized in that: the viscoplasticity parison of extruding by die head, separating dry type typing (7) by steam enters in the die cavity of negative pressure of vacuum orientation room (8), enter screen formula preform section then, forming negative pressure by the steam passage between screen makes parison be adjacent to die cavity, the coolant guiding channel cooling parison that forms between screen, realize that surface gelling enters the floating type screen typing stage again, monoblock type negative pressure of vacuum screen orientation room provides negative pressure, the slit that forms between screen constitutes the vacuum steam passage, make parison continue to be adjacent to the mould rifle, medium channel hole and passage make cooling medium flow on the section bar surface and take away the parison cools moulding, make the further cooling and shaping of parison, quicken the typing of gelation parison again, enter eddy current type water tank (9) and make the moulding of the whole further cooling of section bar fixed dimension.

2, the improvement constructional device of a kind of stock mould according to claim 1 is characterized in that: steam symbiosis, mould can automatic capturings in traction.
