Description
Technical Field
The utility model relates to a deep cavity type cavity blow molding mould, concretely relates to exhaust structure among deep cavity type cavity blow molding mould.
Background
At present, because a traditional deep-cavity hollow blow molding mold is not provided with an exhaust structure, in the actual mold closing process, air between a cavity and a tube blank cannot be completely exhausted due to the fact that the cavity is deep, and cannot be exhausted in the blowing forming process of the tube blank, so that the wall thickness of a finished product is uneven, particularly the wall thicknesses of four corners of the finished product are thin, and the quality of the finished product is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: provided is an exhaust structure in a deep cavity hollow blow mold capable of exhausting air between a cavity and a base pipe.
In order to solve the technical problem, the utility model adopts the technical scheme that: an air venting structure in a deep cavity hollow blow mold comprising: the first half mould and the second half mould can be opened and closed in opposite directions, the first half mould or the second half mould is provided with exhaust mounting through holes respectively facing four corners of a cavity of the first half mould or the second half mould, exhaust caps are arranged in the exhaust mounting through holes, and the specific structure of each exhaust cap comprises: with exhaust installation through-hole matched with diapire and set up along circumference lateral wall on the diapire edge, the diapire on set up a plurality of along circumference and radially arrange and outside open-ended diapire exhaust groove, the lateral wall on set up respectively with diapire exhaust groove one-to-one link to each other, vertically run through the lateral wall exhaust groove, the width of diapire exhaust groove is between 0.1 to 0.2 millimeter, the width of lateral wall exhaust groove is not less than the width of diapire exhaust groove.
Preferably, in the vent structure in the deep cavity hollow blow mold, the width of the bottom wall vent groove is between 0.1 and 0.15 mm.
Preferably, in the vent structure in the deep cavity hollow blow mold, the vent grooves in the bottom wall are uniformly arranged in the circumferential direction.
Preferably, in the air vent structure in the deep cavity hollow blow mold, an end portion of a sidewall of the air vent cap is provided with a chamfer.
The utility model has the advantages that: the utility model discloses an offer exhaust installation through-hole on first half module or the second half module to set up the exhaust cap in exhaust installation through-hole, make at the blowing in-process, can be with the air escape between die cavity and the pipe, make the pipe hug closely on the die cavity inner wall, the finished product wall thickness everywhere of blow molding is unanimous like this, has guaranteed off-the-shelf quality.

Detailed Description
Specific embodiments of the venting structure in a deep cavity hollow blow mold according to the present invention will be described in detail below, taking the first mold half as an example, in conjunction with the accompanying drawings.
As shown in fig. 1, the present invention provides an exhaust structure in a deep cavity hollow blow mold, comprising: a first half mold 3 and a second half mold (belonging to the conventional technology in the field and not described herein), which can be opened and closed in opposite directions, wherein the first half mold 3 is respectively provided with exhaust mounting through holes 31 facing four corners of a cavity thereof, and an exhaust cap 2 is disposed in the exhaust mounting through holes 31, as shown in fig. 3 and 4, the specific structure of the exhaust cap 2 includes: a bottom wall 20 matching with the exhaust mounting through hole 31 on the first half mold 3, and a sidewall 21 circumferentially disposed on an edge of the bottom wall 20, wherein six bottom wall exhaust grooves 201 (the number of the bottom wall exhaust grooves 201 may be determined according to actual conditions) which are radially arranged and open outwards are uniformly formed on the bottom wall 20 circumferentially, the sidewall 21 is respectively formed with sidewall exhaust grooves 211 which are connected with the bottom wall exhaust grooves 201 in a one-to-one correspondence and longitudinally penetrate through the sidewall 21, the width of the bottom wall exhaust groove 201 is between 0.1 and 0.2 mm, preferably between 0.1 and 0.15 mm, and the width of the sidewall exhaust groove 211 is not less than the width of the bottom wall exhaust groove 201 (generally equal to the width of the bottom wall exhaust groove 201); the end of the side wall 21 of the exhaust cap 2 is provided with a chamfer 212.
In the actual blow molding process, air between the cavity and the tube blank can be exhausted through the exhaust cap 2, so that the tube blank is tightly attached to the inner wall of the cavity, the wall thickness of each part of the finished product 1 shown in the blow molding figure 2 including four corners 11 of the finished product is consistent, and the quality of the finished product 1 is ensured.
In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications made by the shapes, structures, characteristics and spirit of the claims of the present invention should be included in the scope of the claims of the present invention.
