RU186824U1 - DRAINAGE DEFLECTOR FOR SLEEPABILITY - Google Patents

Abstract

The inventive utility model relates to assistive devices placed on window openings of vehicle doors.

The inventive utility model is aimed at solving a technical problem, which is to ensure the spillability of the product while reducing its thickness.

The inventive utility model allows to achieve technical results, expressed in reducing the amount of material in the manufacture of the product, without increasing the working cycle time and without upgrading equipment, which ultimately allows to reduce the cost of the product.

The technical problem is solved, and the technical result is achieved due to the fact that the deflector consists of a base (1), a flanging (2) with cutouts (4), to which the inlet gates (3) are fed.

Description

The inventive utility model relates to assistive devices placed on window openings of vehicle doors.

An analogue of the claimed utility model is the “Method and device for injection molding of thin-walled parts under, in fact, constant pressure” according to patent RU No. 2575905, the date of publication of the application June 27, 2015

The analogue is registered with the following formula: A method for injection molding a thin-walled part under essentially constant pressure, comprising the steps of:

- actuate the injection system for feeding the molten thermoplastic material into the mold cavity with increasing power until the specified injection pressure is reached; and

- reduce the power until the mold cavity is within 20% of the full filling with thermoplastic material, in order to maintain an essentially constant injection pressure, which is characterized by a deviation of 30% from the set pressure value;

- while the peak power is achieved before the cavity is filled by 30%.

The casting method of the closest analogue has the following disadvantages:

The first is that the achievement of high filling speeds requires the application of high power, which requires the use of complex and accordingly expensive molding equipment. Moreover, most electric presses do not develop enough power to provide such high filling speeds, or require very complex and expensive drive systems, which significantly increases the capital cost of molding equipment, and makes such production of parts economically disadvantageous.

A second disadvantage is that high filling speeds require very high pressures. The application of such high pressures requires, in turn, the use of very high clamping forces to keep the mold tightly closed during filling, and such high clamping forces make the design of molding equipment very expensive. High injection pressures also require the use of high-strength molds, usually made of hardened tool steels. Such high-strength molds are also very expensive to manufacture, and using them to mold many types of parts may not be economically feasible.

The inventive utility model is aimed at solving a technical problem, which is to ensure the spillability of the product while reducing its thickness.

The inventive utility model allows to achieve technical results, expressed in reducing the amount of material in the manufacture of the product, without increasing the working cycle time and without upgrading equipment, which ultimately allows to reduce the cost of the product.

The technical problem is solved, and technical results are achieved due to the fact that the deflector is made in the form of a one-piece structure of sheet plastic and consists of two structural elements:

- the central part (hereinafter referred to as the base) is a smoothly curved plate element;

- flanging in the form of a strip, which acts as a stiffener, is adjacent to the upper and one of the sides of the base, cuts are made in the flanging, to bring in the inlet sprues, which allows to ensure spillability of the product.

To date, the applicant and the author of the claimed utility model - M. Stroykov manufactured deflectors without cutouts in flanging up to 2 mm thick inclusive, due to the inability to ensure spillability on standard equipment of deflectors with a thickness of less than 2 mm.

Placing cutouts in the flanging of the product made it possible to bring the inlet gates closer to the central longitudinal axis of the product, which, while maintaining the pressure in the gate system and the mold-forming failure of the mold, and also without increasing the working cycle time, made it possible to ensure the spillability of products of various thicknesses from 1.2 mm to 2 mm, while baffles with a thickness of less than 2 mm have high performance characteristics.

These signs form a stable set of essential features sufficient to obtain the desired technical result.

The essence of the utility model is illustrated by drawings:

FIG. 1 3/4 rear view of the product with intake gates;

FIG. 2 3/4 rear view of the resulting product.

The inventive utility model is intended to improve ventilation of the vehicle interior and to prevent precipitation from entering the cabin when the windows are open.

The implementation and use of the claimed utility model is achieved with the achievement of technical results, expressed in reducing the amount of material in the manufacture of the product, without increasing the working cycle time and without upgrading equipment, which ultimately allows to reduce the cost of the product, due to the fact that the product consists of a base (1 ), flanges (2) with cutouts (4), to which the inlet sprues (3) are fed.

Claims (1)

A deflector with cutouts to ensure spillability, consisting of a base and a flange, characterized by the presence in the flanging of cutouts for summing the inlet gates.
