Abstract
The invention relates to the field of forming and in particular relates to a novel heating device for a blowing machine. The heating device comprises a shell, wherein the shell is cylindrical and consists of an inner side aluminum alloy layer and an outer side aluminum layer, wherein an electrothermal wire is arranged between the inner side aluminum alloy layer and the outer side aluminum layer; a separable cooling housing is arranged outside the shell and comprises a cavity, a water inlet and a water outlet. The heating device is difficult to deform; meanwhile, by the adoption of the cooling housing for cooling, the heating device has a good cooling effect; moreover, the cooling speed is uniform, so that the shell is difficult to deform.
Description
Technical field
The present invention relates to forming field, be specifically related to a kind of plastics blow moulding heater.
Background technology
Blowing is a kind of conventional plastic working method, refers to hollow blow molding, is to make to close at by means of gas pressure the method that hot melt parison in mould propels the price of into hollow product.CN203267196U provides a kind of plastics blow moulding heater, and its housing is comprised of aluminum slice, easily distortion, and its cooling dependence is naturally cooling, is subject to externally temperature influence large.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of not yielding, plastics blow moulding heater that can effective temperature-reducing is provided.
Technical scheme of the present invention is as follows:
A plastics blow moulding heater, comprises housing, and described housing is cylindrical, the aluminium alloy layer of inner side and the aluminium lamination in outside, consists of, and between the aluminium alloy layer of inner side and the aluminium lamination in outside, has heating wire; Housing has separable cooling shell outward, and cooling shell comprises cavity, water inlet, delivery port.
Further: described water inlet (7) is symmetric with delivery port (8).
The invention has the beneficial effects as follows:
1, housing of the present invention inner side is aluminium alloy layer, not yielding;
2, the present invention adopts cooling shell to carry out cooling, good cooling effect, and because cooling rate is even, and be difficult for causing housing distortion.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of plastics blow moulding of the present invention;
Fig. 2 is the schematic cross-section of the housing of plastics blow moulding of the present invention;
In figure, 1, housing, 2, aluminium alloy layer, 3, aluminium lamination, 4, heating wire, 5, cooling shell, 6, cavity, 7, water inlet, 8, delivery port.
The specific embodiment
Form by the following examples, foregoing of the present invention is described in further detail again, but the scope that this should be interpreted as to this bright above-mentioned theme only limits to following example, and all technology realizing based on foregoing of the present invention, all belong to scope of the present invention.
As Fig. 1, a kind of plastics blow moulding heater, comprises housing 1, and described housing 1 is cylindrical, the aluminium alloy layer 2 of inner side and the aluminium lamination 3 in outside, consists of, and between the aluminium alloy layer 2 of inner side and the aluminium lamination 3 in outside, has heating wire 4; Housing 1 is outer separable cooling shell 5, and cooling shell 5 comprises cavity 6, water inlet 7, delivery port 8.Described water inlet 7 is symmetric with delivery port 8.
Claims (2)
1. a plastics blow moulding heater, comprise housing (1), it is characterized in that: described housing (1), for cylindrical, is comprised of the aluminium alloy layer (2) of inner side and the aluminium lamination (3) in outside, has heating wire (4) between the aluminium lamination (3) in the aluminium alloy layer of inner side (2) and outside; Housing (1) is outer has separable cooling shell (5), cooling shell (5) to comprise cavity (6), water inlet (7), delivery port (8).
2. plastics blow moulding heater according to claim 1, is characterized in that: described water inlet (7) is symmetric with delivery port (8).
