Description
Technical field
The utility model relates to plastic bushing processing technique field, particularly relates to a kind of plastic bushing closing device.
Background technology
In the production process of refrigerator, need to utilize plastic bushing to complete sealing to refrigerator temperature sensing hole.Mostly existing sealing mode is to adopt silica gel sealing and HF plastic welding manner.Silica gel sealing is the openend utilizing silica gel blocking plastic bushing, has carried out sealing, this mode cost is higher, sealing efficiency comparison is low, and due to the hardening time of silica gel long, be also unfavorable for operation; The welding of HF plastic sleeve pipe utilizes high-frequency energy that two pieces or more than one piece plastic workpiece are welding together, make material heat-dissipating through high frequency and fuse together, although this mode cost is lower, efficiency is higher, but after having welded, the external diameter of sleeve pipe sealing part is greater than the external diameter of refrigerator temperature sensing hole, can not realize the sealing to refrigerator temperature sensing hole.Therefore, a kind of while realization is to plastic pipe sleeve sealing, the plastic bushing closing device of the size and shape of plastic pipe sleeve sealing end can be controlled.
Utility model content
In order to solve the technical problem existed in background technology, the utility model proposes a kind of while realization is to plastic pipe sleeve sealing, the plastic bushing closing device of the size and shape of plastic pipe sleeve sealing end can be controlled.
A kind of plastic bushing closing device that the utility model proposes, for sealing plastic bushing, comprises installing rack, the first heating component, the second heating component;
First heating component comprises cylinder, primary heater, the first mould, and cylinder is fixed on installing rack, and primary heater is connected with the first mould and heats the first mould, and the first mould is fixed on the piston rod front end of cylinder;
Second heating component comprises secondary heater, the second mould, and secondary heater is fixed on installing rack, and secondary heater is connected with the second mould and heats the second mould;
Second mould offers working groove, when cylinder drives the first mould by piston rod, working groove is on the stroke of the first mould, and working groove has the first openend of permission first mould turnover and allows the second openend of plastic bushing turnover, and the first openend communicates and vertical distribution with the second openend.
Preferably, primary heater is installed on the piston rod.
Preferably, the first openend is horizontally disposed, and the second openend is vertically arranged.
Preferably, the piston rod stroke end of cylinder is in working groove.
A kind of plastic bushing closing device that the utility model proposes, in the course of the work, plastic bushing melts under the conductive force of the first mould and the second mould, under the pressure effect of the first mould, plastic bushing after fusing is stressed bonding, thus it is sealed, because capping processes completes in working groove, make the limited size of the sealing end of final cooled plastic bushing in the size and shape of working groove, because working groove size and shape can preset, make the size and shape of the sealing end of plastic bushing controlled equally.The plastic bushing closing device that the utility model proposes, while realization is to plastic pipe sleeve sealing, can control the size and shape of plastic pipe sleeve sealing end.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of plastic bushing closing device that the utility model proposes;
Fig. 2 is the structural representation of the working groove position of the first mould in Fig. 1.
Detailed description of the invention
As shown in Figure 1, Fig. 1 is a kind of plastic bushing closing device structural representation that the utility model proposes, and Fig. 2 is the structural representation of the working groove position of the first mould in Fig. 1.
With reference to Fig. 1 and Fig. 2, the utility model proposes a kind of plastic bushing closing device, for the sealing to plastic bushing, comprise installing rack 1, first heating component 2, second heating component 3;
First heating component 2 comprises cylinder 21, primary heater 22, first mould 23, and cylinder 21 is fixed on installing rack 1, and primary heater 22 is connected with the first mould 23 and heats piston rod 211 front end that the first mould 23, first mould 23 is fixed on cylinder 21;
Second heating component 3 comprises secondary heater 31, second mould 32, and secondary heater 31 is fixed on installing rack 1, and secondary heater 31 is connected with the second mould 32 and heats the second mould 32;
Second mould 32 offers working groove 321, when cylinder 21 drives the first mould 23 by piston rod 211, working groove 321 is on the stroke of the first mould 23, working groove 321 has the first openend of permission first mould 23 turnover and allows the second openend of plastic bushing turnover, first openend communicates and vertical distribution with the second openend, wherein, the first openend is horizontally disposed, and the second openend is vertically arranged.
In the above-described embodiments, because cylinder 21, primary heater 22, first mould 23 connect successively, in cylinder 21 course of work, the first mould 23 moves with the piston rod 211 of cylinder 21 and heated by primary heater 22; Second mould 32 is connected with secondary heater 31 and heats by secondary heater 31.Before realization is to plastic bushing sealing, after plastic bushing being inserted working groove 321 certain length, start cylinder 21, the first mould 23 is slowly moved to the direction, working groove 321 place of the second mould 32, and finally enters working groove 321.Because the first mould 23 and the second mould 32 all have uniform temperature, plastic bushing melts under the conductive force of the first mould 23 and the second mould 32, and the plastic bushing after fusing is sticked together by the pressure effect of the first mould 23, completes the sealing to plastic bushing.
In specific design process, heater 22 is arranged on piston rod 211.
In specific design process, piston rod 211 end of travel of cylinder 21 is in working groove 321, and in plastic bushing capping processes, the first mould 23 can not contact with bottom the working groove 321 of the second mould 32, effectively protects the first mould 23 and the second mould 32.
A kind of plastic bushing closing device that the utility model proposes, in the course of the work, plastic bushing melts under the conductive force of the first mould 23 and the second mould 32, under the pressure effect of the first mould 23, plastic bushing after fusing is stressed bonding, thus it is sealed, because capping processes completes in working groove 321, make the limited size of the sealing end of final cooled plastic bushing in the size and shape of working groove 321, because working groove 321 size and shape can preset, make the size and shape of the sealing end of plastic bushing controlled equally.The plastic bushing closing device that the utility model proposes, while realization is to plastic pipe sleeve sealing, can control the size and shape of plastic pipe sleeve sealing end.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
