Abstract

The utility model relates to a die core for producing a filter, relates to the field of production dies of the filters, and solves the problem of poor tightness of the die core in the prior art. The die core comprises a die core body, wherein grid plates arrayed in an equidistant manner are arranged at the die core body; and the die core body is characterized in that U-shaped grooves are formed in the middles of the grid plates, and included inverted angles are arranged at the groove sides of the U-shaped grooves. According to the die core for producing the filter, the structure is simple, and the design is reasonable; and the U-shaped grooves are formed in the grid plates of the original die core body, compression sealing regions can be formed on parts high than two sides of the U-shaped grooves, the tightness of two ends of the filter core is guaranteed when the forming of filter paper or non-woven fabrics is guaranteed, and the product quality is effectively improved.

Description

Produce the core rod of cleaner

Technical field:

The utility model relates to a kind of filter element mould, relates in particular to a kind of core rod of producing cleaner.

Background technology:

Remove the device of airborne granulometric impurity.Reciprocating machine (internal combustion engine, reciprocating compressor etc.) when work, just will aggravate the wearing and tearing of part if contain the impurity such as dust in the air amount, so air filter must be housed.Air filter is comprised of filter core and housing two parts.The major requirement of air filter is that filtering efficiency is high, flow resistance is low, can uses and service free continuously the long period.

Normally used air filter is in order to increase the filter area of filter core, and filter core paper or the nonwoven with filter core is folded into waveform usually, behind filter core paper or the nonwoven folding forming sealing be fixed on framed or the filter core support on.Said process in process of production normal operation mould is finished, and filter core paper or nonwoven pass through the Mould Machining moulding, and realizes that by mould sealing is fixing.Be shaped with at present a plurality of screens of spaced set on the core rod body for the production of the mould of processing cleaner, a plurality of screens are parallel.Because the screen surface is the plane, in the time of filter core paper or nonwoven moulding, sealed at both ends effect is bad, poor product quality.

The utility model content:

Technical problem to be solved in the utility model is to overcome the defective of prior art, and a kind of core rod that can guarantee the production cleaner of the sealed at both ends property of filter core is provided.

Technical problem to be solved in the utility model realizes by the following technical solutions.

Comprise the core rod body, the core rod system has the screen of equidistant arrangement, it is characterized in that: described screen mid portion is shaped with U-shaped groove, and U-shaped groove both sides just form the pressing seal area, when guaranteeing filter core paper or nonwoven moulding, also guarantees the sealing at filter core two ends.

The trough rim of described U-shaped groove is shaped with oblique chamfering.

The utility model is simple in structure, reasonable in design, screen at original core rod body is provided with U-shaped groove, can make U-shaped groove both sides the raised area form the pressing seal area, when guaranteeing filter core paper or nonwoven moulding, also guaranteed the sealing at filter core two ends, Effective Raise product quality.

Description of drawings:

Fig. 1 is front view of the present utility model;

Fig. 2 is top view of the present utility model.

The specific embodiment:

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 1 and Figure 2, a kind of core rod of producing cleaner, comprise core rod body 4, core rod body 4 is shaped with the screen 3 of equidistant arrangement, screen 3 mid portions are shaped with U-shaped groove 1, and U-shaped groove 1 both sides just form pressing seal area 2, when guaranteeing filter core paper or nonwoven moulding, also guarantee the sealing at filter core two ends, the trough rim of U-shaped groove 1 is shaped with oblique chamfering.

More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
