Detailed Description

The blow structure of the plastic mold of the present utility model will be described in more detail with reference to the accompanying drawings, in which preferred embodiments of the present utility model are shown, it being understood that the utility model described herein may be modified by those skilled in the art while still achieving the advantageous effects of the utility model. Accordingly, the following description is to be construed as broadly known to those skilled in the art and not as limiting the utility model.

The utility model is more particularly described by way of example in the following paragraphs with reference to the drawings. Advantages and features of the utility model will become more apparent from the following description and from the claims. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the utility model.

As shown in fig. 1 and 2, an embodiment of the present utility model provides a blowing structure of a plastic package mold, which includes a blowing gun 1, a protective sleeve, and a plurality of auxiliary nozzles 2.

The protective sheath sets up the muzzle end of blowing gun 1 wraps up the protection to blowing gun 1's muzzle, prevents that blowing gun 1 from causing the muzzle direct to contact with the surface of mould because of external or factor of labor in the use, and then causes the mould to appear the mar, influences the condition emergence of follow-up product effect.

Specifically, the protective sleeve comprises an expansion part 3 and a folding part 4;

the expansion part 3 is wrapped on the outer wall of the air blowing gun 1, when the air blowing gun 1 is prevented from being taken obliquely for use, the bottommost end of the air blowing gun 1 is contacted with the die, an isolation gap is formed between the air blowing gun 1 and the die through the expansion part 3, and the die is protected.

The folding part 4 is sleeved at the end part of the air blowing gun 1 and is provided with an opening, and the opening is communicated with the air blowing gun 1, namely, the air blown out by the air blowing gun 1 can be discharged along the opening so as to act on the surface of the die, and the purpose of cleaning the die is achieved.

Further, when the air blowing gun 1 blows air, the folded portion 4 is pulled to deform and expand. Namely, when the air gun 1 works, the folding part 4 can correspondingly expand, so that protection is formed between the air gun 1 and the die again, and the condition that the air gun 1 is directly contacted with the die due to damage of the expansion part 3 caused by external factors is avoided, so that the protection effect on the die is further improved.

It should be noted that, the expansion portion 3 and the folding portion 4 can be used as the carrying ends of the air gun 1, that is, when the air gun 1 is used, the expansion portion 3 and the folding portion 4 can be directly acted on the mold, at this time, the air gun 1 is only pushed to blow along different angles by a person, so that the carrying force required by the person to lift the air gun 1 is reduced.

Furthermore, to enhance the cleaning effect of the air gun 1, the folded portion 4 has a plurality of annular flanges; a plurality of said auxiliary nozzles 2 are arranged on said annular flange. Wherein, be perpendicular setting between auxiliary nozzle 2 and the opening, so when blowing air gun 1 blows, gas can be respectively along auxiliary nozzle 2 and opening blowout, realizes the jet function of diversified multi-angle, promotes the cleaning effect to the mould.

In other embodiments, the protective sleeve further comprises a threaded sleeve 5 for facilitating the mounting of the protective sleeve on the air gun 1.

Specifically, the thread sleeve 5 is disposed in the middle of the expansion portion 3 and is connected to the folding portion 4; the end of the air blowing gun 1 is provided with threads matched with the thread sleeve 5. That is, the expansion part 3 and the folding part 4 are connected in series to the air gun 1 by screwing the screw sleeve 5 to the air gun 1.

When the thread sleeve 5 is in threaded connection with the air blowing gun 1, the expansion part 3 is abutted against the outer wall of the air blowing gun 1.

As shown in fig. 2, the expansion part 3 is provided as an annular balloon, and the middle part of the expansion part 3 is provided with an annular cavity. Wherein, the annular cavity is used for expansion portion 3 to cushion deformation, namely when expansion portion 3 acts on the mould, when receiving blowing rifle 1 to press effort, but extrusion expansion portion 3 deformation to this avoids the risk that blowing rifle 1 directly contacted with the mould.

Because the expansion part 3 is arranged in a ring shape, the air gun 1 can not be contacted with the mould when being placed along any angle, and the flexibility of the air gun 1 in use is improved

To ensure that the folded part 4 can expand along a predetermined track when being subjected to the aerodynamic force of the air gun 1, the situation that the opening cannot be normally ventilated due to the deformation of the folded part 4 along any angle is prevented.

The middle part of the folded part 4 is provided with a sliding sleeve 6.

One end of the sliding sleeve 6 is fixedly connected with the folding part 4, the other end of the sliding sleeve is in sliding clamping connection with the muzzle of the air blowing gun 1, namely, the sliding sleeve 6 is used as a main supporting point of the folding part 4, and when the sliding sleeve 6 slides, the folding part 4 is pushed to be unfolded and expanded.

When the air gun 1 blows, air is discharged to the outside along the opening, the sliding sleeve 6 is pushed to move, and a plurality of annular flanges are pulled to deform in sequence, so that the expansion of the folding part 4 can be completed, the air gun 1 is wrapped in the subsequent process, and the end part of the air gun 1 is prevented from being in direct contact with a die.

It should be noted that, the outer wall of one end of the sliding sleeve 6 connected with the muzzle of the air gun 1 is provided with an elastic bead, which is similar to an umbrella bead in an umbrella in the prior art, and the sliding connection between the sliding sleeve 6 and the air gun 1 is completed in a clamping manner, so that when the air gun 1 runs, the air can also push the sliding sleeve 6 to slide, and the annular flange is unfolded in turn.

It should be noted that, the aerodynamic force of blowing out of the air blowing gun 1 should be smaller than the clamping force formed between the sliding sleeve 6 and the air blowing gun 1 to prevent the sliding sleeve 6 from separating from the air blowing gun 1, so that the function of expanding the folded portion 4 along the predetermined track cannot be realized.

Wherein a surrounding chamber is formed between the outer wall of the sliding sleeve 6 and the inner wall of the folded part 4.

To facilitate the drainage of the gas in the blowing gun 1 into the surrounding chamber for subsequent evacuation of the gas from the auxiliary nozzle 2 to the outside.

The outer wall of the sliding sleeve 6 is provided with a plurality of ventilation holes 7; when the air gun 1 blows, part of the air is transferred into the surrounding cavity along the air holes 7.

In the present embodiment, a specific folded portion 4 is provided to secure the protection effect of the end portion of the air gun 1. The folding part 4 is provided with a corrugated telescopic sleeve and is made of silica gel.

It will be apparent to those skilled in the art that various modifications and variations can be made to the present utility model without departing from the spirit or scope of the utility model. Thus, it is intended that the present utility model also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
