Description
Technical Field
The invention relates to the field of ceramic electric heating rings for injection molding machines, which is mainly applied to a wrapping structure for assembling an internal wire-penetrating ceramic component of a heater and a metal shell.
Background
The inside ceramic subassembly of ceramic electric heating ring on the existing market is many to need extra sheet metal component cooperation assembly with shell subassembly, buckles twice through the bender to the sheet metal component earlier, again through with metal casing welding assembly together, relate to the machine and bend and technology such as welding, not only assembly efficiency is low, and used panel beating of bending is the solid moreover, influences the heat conduction.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the defects in the prior art and provides a wrapping structure for assembling a ceramic electric heating coil wire-penetrating ceramic component and a shell for an injection molding machine.
In order to solve the technical problem, the solution of the invention is as follows:
the utility model provides a wrapping structure for assembling a ceramic electric heating coil wire-penetrating ceramic component and a shell for an injection molding machine, which comprises a metal shell and a wire-penetrating ceramic component; the end part of the metal shell is provided with a wrapping structure, and the metal shell wraps the wire-penetrating ceramic assembly through the wrapping structure; the edge covering structure and the metal shell are integrally in a U-shaped structure, the edge covering structure comprises a first bending surface and a second bending surface, the first bending surface is positioned at the top surface of the wire penetrating ceramic assembly, and the second bending surface is positioned at the inner side surface of the wire penetrating ceramic assembly; a plurality of elongated holes are formed in the first bending surface along the extension of the top of the wire-penetrating ceramic, so that a plurality of connecting ribs are formed.
As an improvement, heat insulation cotton is arranged between the metal shell and the wire-penetrating ceramic component.
As an improvement, the second bending surface is provided with a plurality of heat conducting holes for transferring heat.
Description of the invention
The edge covering structure is bent into a U shape by the metal shell during assembly, and wraps the internal heat insulation cotton and the wire penetrating ceramic assembly to prevent dislocation and separation in the process of installing and using the heater, so that the heater is damaged; the wire-through ceramic component is used as a heating main body of the heater and has the functions of heating, insulation and heat conduction; the heat insulation cotton is arranged between the wire-penetrating ceramic component and the metal shell, so that heat can be prevented from being lost outwards; the metal shell ensures the integrity of the heater, and the metal edge-covering structure at the tail part is additionally provided with a bending square hole and a heat conducting hole, so that the heater is easy to bend manually.
Compared with the prior art, the invention has the beneficial effects that:
the metal shell is provided with a wrapping structure, so that the equipment bending and welding procedures are saved, and the assembly efficiency of the heater is improved; the introduction of the heat conduction hole improves the heating efficiency of the heater.

Detailed Description
Examples
As shown in fig. 1 and 2, the edge covering structure for assembling the ceramic electric heating coil wire-penetrating ceramic component and the outer shell for the injection molding machine comprises a metal outer shell 1 and a wire-penetrating ceramic component 3. The end part of the metal shell 1 is provided with a wrapping structure, and the metal shell 1 wraps the wire-penetrating ceramic component 3 through the wrapping structure. The structure of borduring is U type structure with metal casing 1 is whole, and the structure of borduring includes that the face is buckled to first face of buckling and second, and the first face of buckling is located 3 top surfaces of threading ceramic subassembly, and the second is buckled the face and is located 3 medial surfaces of threading ceramic subassembly department. A plurality of elongated holes are formed in the first bending surface along the extension of the top of the wire-penetrating ceramic, so that a plurality of connecting ribs are formed. The metal casing 1 is bordured and is handled through special trompil structure, makes it need not to follow the splice bar manual bending that the elongated hole department left easily with the help of the bender, reaches the effect of parcel thermal-insulated cotton 2 and threading ceramic subassembly 3, improves the installation effectiveness. The narrow connecting ribs of the edge of the metal shell 1 can better fit the wire-penetrating ceramic component 3 and the heated body under the locking stress.
And heat insulation cotton 2 is also arranged between the metal shell 1 and the wire-penetrating ceramic component 3. 3 circular telegrams of wire ceramic subassembly generate heat, under the thermal-insulated effect of thermal-insulated cotton 2 for the heat is as much as possible the direction by the heating member, and it has the square heat conduction hole of many places to open on the second face of buckling for the heating member is given in the heat dissipation, makes heating efficiency obtain promoting.
Any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention are still within the technical scope of the present invention, unless the content of the technical solution of the present invention is departed from.
