Abstract
The invention discloses a local cooling mechanism for preform molding. One end of a strut is connected with a fixed connecting seat, and the other end of the strut is detachably connected with a cooling nozzle; an airflow channel communicated with a cooling gas source supply pipeline is arranged in the cooling nozzle, and a plurality of air injection holes communicated with the airflow channel are uniformly formed in one end of the cooling nozzle. A cooling gas source blows air to the corresponding part of a preform through the air injection holes, so that the preform can be uniformly cooled; the wall of the part is thick during re-molding, and thus the cracking phenomenon is avoided during blow molding.
Description
[technical field]
The present invention relates to blow molding machinery, especially a kind of Local cooling mechanism for bottle embryo forming.
[background technology]
A lot of bottle, it is all corresponding is provided with handle, but due to bottle, to be used for other wall thickness of position and bottle of mounting knob consistent, and thinner, bottle in use, the bottle that particularly Capacity Ratio is larger, because it is loaded with corresponding liquid, during effect handle, suffered by bottle mounting knob position, stress ratio is more concentrated, the thus easy fatigue rupture in this position.In order to solve the problems of the technologies described above, the mode adopted in prior art is: before bottle embryo blow molding bottle, with cooling block, Local cooling is carried out to bottle embryo corresponding site, the bottle embryo processed thus, when carrying out blow molding again, then corresponding thickening for the position of mounting knob on bottle, add the bonding strength of handle attachment part position.But adopt and carry out Local cooling in this way, because cooling block is concentrated the Local cooling of bottle embryo, excessive temperature differentials, therefore bottle embryo is when blow molding bottle, easily occurs the phenomenon of breaking, and causes defective products to increase, affects product quality.
Namely the present invention researchs and proposes for the deficiencies in the prior art.
[summary of the invention]
The technical problem to be solved in the present invention is to provide a kind of Local cooling mechanism for bottle embryo forming, pole one end is connected with fixed connecting base, the pole other end is removably connected with cooling spray, be provided with in cooling spray and supply the gas channel cooling gas source pipe and be communicated with, cooling spray one end is laid with several jet apertures be communicated with gas channel, cooling source of the gas is blown to bottle embryo corresponding site by jet aperture, it can be made to obtain Homogeneous cooling, both made this position wall thickness thicker during reshaping, and avoided producing fracture phenomena during guarantee blowing again.
For solving the problems of the technologies described above, a kind of Local cooling mechanism for bottle embryo forming of the present invention, adopts following technical scheme:
A kind of Local cooling mechanism for bottle embryo forming of the present invention, comprise fixed connecting base and pole, described pole one end is connected with fixed connecting base, the described pole other end is removably connected with cooling spray, be provided with in described cooling spray and supply the gas channel cooling gas source pipe and be communicated with, described cooling spray one end is laid with several jet apertures be communicated with gas channel.
Described jet aperture is five, and one of them is positioned at center, cooling spray end, and all the other four uniform around cooling spray end center circumferential.
Distance of center circle on described cooling spray end between adjacent two jet apertures is equal.
Described cooling spray is provided with the connecting hole for being connected with pole and the connecting hole that makes that is communicated with connecting hole keeps the clamping clamping pole to stitch.
Compared with prior art, when adopting a kind of Local cooling mechanism for bottle embryo forming of the present invention to carry out Local cooling to bottle embryo, there is the uniform advantage of cooling, improve a bottle yields for embryo blow molding bottle, and ensure that bottle mounting knob position is connected reliably with handle.

[detailed description of the invention]
Below in conjunction with accompanying drawing, embodiments of the present invention are elaborated.
A kind of Local cooling mechanism for bottle embryo forming of the present invention, comprise fixed connecting base 1 and pole 2, described pole 2 one end is connected with fixed connecting base 1, described pole 2 other end is removably connected with cooling spray 3, be provided with in described cooling spray 3 and supply the gas channel 31 cooling gas source pipe and be communicated with, described cooling spray 3 one end is laid with several jet apertures 32 be communicated with gas channel 31.
Described in the embodiment of the present invention, jet aperture 32 is five, one of them is positioned at center, cooling spray 3 end, all the other four uniform around cooling spray 3 end center circumferential, and distance of center circle between adjacent two jet apertures 32 is equal, the refrigerating gas that jet aperture 32 is sprayed directive bottle embryo corresponding site equably, when this corresponding site is bottle embryo forming bottle, corresponding to the position of mounting knob, guarantee cooling evenly, the temperature of this corresponding site the segment smoothing transition be not cooled with surrounding.
Described cooling spray 3 is provided with the connecting hole 33 for being connected with pole 2 and the connecting hole 33 that makes that is communicated with connecting hole 33 keeps the clamping clamping pole 2 to stitch 34.The aperture of connecting hole 33 is more smaller than the diameter of pole 2, and pole 2 and connecting hole 33 are interference fit, and because clamping seam 34 is communicated with connecting hole 33, clamping seam 34 keeps pole 2 to clamp, and facilitates maintenance or the replacing of cooling spray 3.
As shown in Figure 5, for the present invention's structural representation in the application, after bottle embryo 5 completes overall heating, bottle embryo 5 is put into mould 6, now, controlled cooling model gas source pipe 4, the jet aperture 32 of cooling spray 3 is made to spray refrigerating gas, this refrigerating gas sprays to the local of bottle embryo 5, be connected with handle after this is locally-shaped, make the temperature of this local low compared with other region, and the temperature in this local temperature and other not cooled region has the advantages that to seamlessly transit, multiple jet aperture 32 is adopted to cool, Local cooling temperature can be avoided too low and be unfavorable for shaping phenomenon.
