Abstract
The utility model discloses a kind of new blow head suitable for shoulder Cheng Mo wide, the type blow head is provided with the air inlet pipe for being blown in the die cavity to shoulder Cheng Mo wide.The new blow head is provided with some inlet channels, and the one side fitted with the top surface of shoulder Cheng Mo wide on new blow head is provided with annular groove, and the annular groove is connected with inlet channel.The air discharge duct for being vented is additionally provided with new blow head, the air discharge duct is connected with annular groove.Top surface that can be effectively to shoulder Cheng Mo wide by new blow head of the present utility model is cooled down, to reduce the temperature of the top surface of shoulder Cheng Mo wide, prevent temperature at the shoulder of the short neck product of shoulder wide too high and the defects such as the fissure of displacement, torticollis occur, reduce product fraction defective, improve the quality of product.
Description
Technical field
The utility model belongs to the blow head technical components of mould, is related to a kind of new air blowing suitable for shoulder Cheng Mo wide
Head.
Background technology
Reference picture 1, existing blow head 2 is installed on shoulder wide on the top surface of mould 1, the bottom surface of existing blow head 2 with it is wide
Shoulder is fitted into the top surface of mould 1, and the air inlet pipe on existing blow head 2 stretches into shoulder wide into the die cavity 11 of mould 1.During shaping, due to
The limitation of equipment can only blow cooling wind and be cooled down into mould 1 with to shoulder wide to shoulder wide into the side of mould 1, and can not directly to shoulder wide
Top surface into mould 1 blows cooling.But shoulder wide into mould 1 top surface in shaping heating temperature rise it is fast, due to shoulder wide into mould 1
Top surface cannot effectively cool down, shoulder wide is higher into temperature at the shoulder 12 of mould 1, Peng's bulging deformation that is heated easily occurs, and causes bottle
The defects such as the shoulder fissure of displacement, torticollis.
Therefore, necessary design is applied to the new blow head of shoulder Cheng Mo wide, by the new blow head to shoulder wide into
The top surface of mould is effectively cooled down, to reduce fraction defective, improve product quality.
Utility model content
The purpose of this utility model is to provide a kind of new blow head suitable for shoulder Cheng Mo wide, by the new blow head
Top surface to shoulder Cheng Mo wide is effectively cooled down, so that fraction defective is reduced, improve product quality.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：It is a kind of suitable for shoulder Cheng Mo's wide
New blow head, the type blow head is provided with the air inlet pipe for being blown in the die cavity to the shoulder Cheng Mo wide, described new to blow
Some inlet channels are provided with a fit of anger, and the one side fitted with the top surface of the shoulder Cheng Mo wide on the new blow head is provided with
Annular groove, the annular groove is connected with the inlet channel, and the air discharge duct for being vented is additionally provided with the new blow head, should
Air discharge duct is connected with the annular groove.
Further, the new blow head Shang Yanqi centers are evenly provided with four inlet channels.
Further, the inlet end of the inlet channel is near the air inlet pipe, the outlet side of the inlet channel away from
The air inlet pipe.
Further, the annular groove is in annular.
Further, the cross section semicircular in shape of the air discharge duct.
The utility model beneficial effect：New blow head of the present utility model, is input into by inlet channel in annular groove
Cooling wind is realized effectively cooling down the top surface of shoulder Cheng Mo wide, so as to reduce the temperature of the top surface of shoulder Cheng Mo wide, prevents width
Temperature is too high and the defects such as the fissure of displacement, torticollis occur at the shoulder of the short neck product of shoulder, reduces product fraction defective, improves product
Quality.

Specific embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical scheme in the utility model embodiment is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole embodiments.
Based on the embodiment in the utility model, what those of ordinary skill in the art were obtained under the premise of creative work is not made
Every other embodiment, belongs to the scope of the utility model protection.
As shown in Figures 2 and 3, a kind of new blow head 3 of the present embodiment.The center of the new blow head 3 is provided with
For to shoulder wide into the air inlet pipe 31 blown in the die cavity 11 of mould 1.The Shang Yanqi centers of new blow head 3 are equably machined with four
Inlet channel 32, the upper end of inlet channel 32 is inlet end, and lower end is outlet side, and wherein the inlet end of inlet channel 32 is close to
Tracheae 31, the outlet side of inlet channel 32 is away from air inlet pipe 31.A ring for being in annular is machined with the bottom surface of new blow head 3
Shape groove 33, the annular groove 33 is connected with inlet channel 32.The bottom surface of new blow head 3 be also machined with four for be vented horizontal stroke
The air discharge duct 34 of section semicircular in shape, four air discharge ducts 34 are connected with annular groove 33 respectively.
Reference picture 5, new blow head 3 is installed on shoulder wide into the top surface of mould 1, bottom surface and the width of new blow head 3 when using
Shoulder fits into the top surface of mould 1, and inlet channel 32 is connected with outside cooling system.During shaping, outside cooling system is logical to air inlet
Input cooling wind in road 32, cooling wind is through inlet channel 32 into annular groove 33 so as to be carried out effectively into the top surface of mould 1 to shoulder wide
Cooling, finally cools down wind and discharges outside from annular groove 33.
New blow head of the present utility model, outside cooling system can effectively to width by the new blow head during shaping
The top surface of shoulder Cheng Mo is cooled down, and reduces the temperature of the top surface of shoulder Cheng Mo wide, so as to prevent the shoulder of the short neck product of shoulder wide
