Description
Technical field
This utility model relates to blow moulding machine technical field, is specifically related to the mould clamping structure of a kind of blow moulding machine.
Background technology
Commercially available have a kind of blow moulding machine, after granular plastic heating is mainly become molten by it, then makes molten
Plastics substantially form the stock of hollow tubular, outside stock, cover mould, and inflate in stock, cause stock by gas
Body pressure compress and towards the die cavity inwall modification of mould, the die cavity same shape with mould that just can obtain after stock cools down
Goods.
No matter described blow moulding machine is intended to which kind of plastic processing is become goods, and the processing temperature of mould all can affect system
The quality of product with make yield, as a example by granular polylactic acid plastic, the temperature of its mould to be made is maintained at 80.C-
130.Between C, the goods so made with polylactic acid plastic just can have good physical property and can have higher system
Become yield.But the general blow moulding machine die holder that is used for providing mould to combine does not has to adjust a design of temperature, thus
At the beginning during operation, the temperature of mould is less than 80.C, the quality causing goods is the best, and along with the activity duration extends, mould is inhaled
Receiving the heat of molten polylactic acid and heat up, the temperature causing mould may be between 80.C-130.C, but the activity duration continue to prolong
After length, the temperature of mould may will raise and more than 130.C, the cooling effect that so will result in mould is the best, thus goods
Final goods may be caused to there may be the problem that deflection is excessive in the state bottom knockout shaped the most completely.Though it addition,
So there is a kind of traditional mould itself to be i.e. designed with heating and the device of cooling or pipeline, but mould itself is designed with and goods
The die cavity of same shape, therefore must avoid die cavity, the most directly set when the heating on mould and chiller or circuit design
The heating being placed on mould and chiller are difficult to so that mould bulk temperature is uniform, and each different mould is required for setting
Putting heating and chiller or pipeline, the cost of its mould is the highest.
Utility model content
This utility model overcomes the deficiencies in the prior art, it is provided that a kind of for facilitating temperature controlled blow moulding machine
Mould clamping structure.
In view of the problems referred to above of prior art, according to an aspect of the present utility model, ask for solving above-mentioned technology
Topic, this utility model by the following technical solutions:
The mould clamping structure of a kind of blow moulding machine, it includes upper bolster, die shoe and temperature control system, described temperature control system bag
Including the U-tube being arranged on upper bolster and die shoe, described U-tube is copper pipeline, and described U-tube is divided into upper half circular pipe
With lower semi-circular pipeline, the inwall of described upper half circular pipe and lower semi-circular pipeline is both provided with heat transfer sheet, described upper half
Circular pipe and lower semi-circular pipeline are by being welded together；Described temperature control system also includes being arranged in described U-tube
Inner tube, heater is set in said inner tube.
In order to this utility model is better achieved, further technical scheme is:
According to an embodiment of the present utility model, said inner tube is positioned in the middle part of described U-tube.
Compared with prior art, one of the beneficial effects of the utility model are:
The mould clamping structure of blow moulding machine of the present utility model, by the heat transfer sheet arranged, improves when needs dispel the heat
The radiating efficiency of whole mould, when needs heat, improves again intensification efficiency, facilitates the control to temperature.
Accompanying drawing explanation

Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in further detail, but embodiment of the present utility model is not
It is limited to this.
As shown in Figure 1 and Figure 2, Fig. 1 is the mould clamping structure signal of the blow moulding machine according to one embodiment of this utility model
Figure, Fig. 2 is the temperature control system structural representation according to one embodiment of this utility model, the clamping knot of a kind of blow moulding machine
Structure, it includes upper bolster 1, die shoe 2 and temperature control system, and described temperature control system includes being arranged on upper bolster 1 and die shoe 2
U-tube 3, described U-tube 3 is copper pipeline, and described U-tube 3 is divided into upper half circular pipe 5 and lower semi-circular pipeline 6, described on
It is both provided with heat transfer sheet 7, described upper half circular pipe 5 and lower semi-circular on the inwall of semicircle pipeline 5 and lower semi-circular pipeline 6
Pipeline 6 is by being welded together；Described temperature control system also includes the inner tube 8 being arranged in described U-tube 3, said inner tube 8
Heater 4 is inside set.
