Abstract

The utility model discloses a mold for producing dustproof sleeves, which comprises a fixed template (1) and a plurality of movable templates (4) and is characterized in that an inflating passage (2) is arranged in the fixed template (1) and is communicated with the front end part of a mold head (3) through the fixed template (1); and in a demolding technology, an air pump is used for inflating compressed air into the dustproof sleeve through the inflating passage to facilitate demolding. Thereby, the utility model has the advantages that the demolding is easy, the dustproof sleeve is not extended and ruptured, the product quality is improved, the service life is prolonged, the replacement times are greatly reduced, the cost is saved and the automobile steering mechanism is protected against wear.

Description

A kind of mould of producing dirt-proof boot

Technical field:

The utility model relates to the mold machining technology field, is a kind of mould of producing dirt-proof boot specifically.

Background technology:

Now used automobile dirt-proof boot (obturating cup), beam etc. on the auto industry are generally that elastomeric material makes, because the performance of rubber self, determine that it is a consumable accessory, but the dirt-proof boot replacing is pretty troublesome, if untimely replacing, automobile steering mechanism there are wearing and tearing, influence its life-span.Chinese patent: ZL02135880.x, denomination of invention: a kind of dirt-proof boot and preparation method thereof, be that a kind of employing polyurethane elastomer material is made dirt-proof boot, the wearability of dirt-proof boot, mechanical performance, cold resistance, weather resisteant and and corrosivity all is better than the dirt-proof boot that elastomeric material is made, and production efficiency height; But differ too big because the shape of dirt-proof boot is concavo-convex, when the releasing process step, the bad depanning of product, sometimes cause dirt-proof boot to elongate, break, influence product quality, be installed in when using on the automobile, shorten service life, break easily, thereby influence its life-span, bring the trouble of Motor Maintenance aspect and the wearing and tearing of steering mechanism to the user.

Summary of the invention:

The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of mould of producing dirt-proof boot is provided, and demoulding difficulty influences the problem of product quality when mainly solving existing dirt-proof boot and preparing.

In order to achieve the above object, the utility model is achieved in that a kind of mould of producing dirt-proof boot, and it comprises quiet template and polylith moving platen, and its special character is to establish filling channel on the quiet template, and filling channel communicates with the leading section of die head by quiet template.

Compared with the prior art a kind of mould of producing dirt-proof boot described in the utility model has following good effect; on mould, offer filling channel; adopt the compressed air inflation demoulding; make the demoulding easy; dirt-proof boot does not have elongation, fracture phenomena, and product quality improves, thereby improves its service life; significantly reduce it and change number of times, save cost and protect automotive steering structure not to be worn simultaneously.

Description of drawings:

Fig. 1 is a mould die opening state structural representation of the present utility model;

Fig. 2 is the utility model mould inflated condition schematic diagram;

Fig. 3 is that the utility model mould ejects view.

The specific embodiment:

In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and describe a kind of mould of producing dirt-proof boot of the utility model in detail.

Embodiment 1, referring to Fig. 1,2,3, adopts injector to produce dirt-proof boot, and the injector mould comprises quiet template 1 and polylith moving platen 4, offers filling channel 2 on quiet template 1, and filling channel 2 communicates with the leading section of die head 3 by quiet template 1.

A kind of mould of producing dirt-proof boot described in the utility model, adopt above-mentioned injector mould, select for use polyurethane elastomer material routinely technology carry out raw material drying, mold heated, Shooting Technique step, after Shooting Technique is finished, cool off after 120 seconds, enter the releasing process step, at first injector is carried out the die sinking action, at this moment, under the effect of drawing back of moving platen, mould is in die opening state; After treating that mould is opened fully, 10 MPa compressed air inside the air pump are charged to the die head end by filling channel enter the dirt-proof boot the inside, dirt-proof boot bulging under the inflation of gas is got up, after the sufficient bulging of dirt-proof boot, the hydraulic pressure ejecting mechanism of injector begins action, eject forward, dirt-proof boot can successfully be ejected mould, finishes the releasing process of dirt-proof boot.

Claims

1. mould of producing dirt-proof boot, it comprises quiet template (1) and polylith moving platen (4), it is characterized in that establishing on the quiet template (1) filling channel (2), filling channel (2) communicates by the leading section of quiet template (1) with die head (3).
