Abstract
The invention discloses a heater with an adjustable length. The heater comprises a spring heating ring, wherein a layer of cylindrical sleeve body for coating the spring heating ring is cast outside the spring heating ring; the sleeve body is divided into an upper sleeve body and a lower sleeve body, which are separated with one another; a circle of negative step and a circle of positive step, which are matched with each other, are respectively arranged at the connecting surfaces of the upper sleeve body and the lower sleeve body; the positive step penetrates into the negative step. By adopting the heater with the adjustable length disclosed by the invention, on one hand, four sides of the spring heating rings are subjected to heat exchange with the sleeve body by casting the spring heating ring into the sleeve body, do not deform due to temperature rise, and tightly contact the sleeve body all the time, so that the heating efficiency is improved; on the other hand, a spring heater extending due to deformation is compensated by dividing the sleeve body into the upper sleeve body and the lower sleeve body, which are separated with one another; heating of various lengths of nozzles is achieved by properly lengthening the spring heater.
Description
Technical field
The present invention relates to a kind of hot runner mould system, particularly relate to and a kind ofly nozzle etc. is heated the heater of adjustable-length.
Background technology
Heater is the most common a kind of parts in the hot runner mould system; its primary structure is a sleeve and is located at the interior helical spring heater of sleeve; the spring heaters set on the outer circumference surface of nozzle; after the energising of spring heater, heat up; nozzle in it is heated, the main effect of sleeve be protection spring heater not reason be subjected to the effect of external force and destroyed.Existing heater, for avoiding adding spacing between the turn of thermal expansion post-heater because strengthening when heater, and a part that makes the spring heater reaches outside sleeve body and the nozzle body, usually sleeve body is divided into two sections, two ends of spring heater are separately fixed at two ends of sleeve body, by the expansion joint between two sections sleeve bodies, the change that compensates the turn spacing that causes because of spring heater intensification expansion is big.But the heater of existing this adjustable length, only be single face or three face contact types between its spring heater and the sleeve body, behind spring heater elevated temperature deformation, contact-making surface between itself and the sleeve body can reduce to break away from fully even, influenced the heat conduction of spring heater to sleeve body, simultaneously, the gap that forms between two sections sleeve bodies also makes heat run out of wasted heat easily.
Summary of the invention
For overcoming above-mentioned defective, the present invention aims to provide a kind of can efficiently the heating sleeve body, and the while is the heater of the adjustable-length of energy savings again.
For achieving the above object, the technical solution used in the present invention is: a kind of heater of adjustable length, comprise a spring heating collar, described spring heating collar is cast with one deck outward and wraps being of this spring heating collar sleeve body cylindraceous, and described sleeve body is divided into the upper bush body that is separated from each other and the cylindrical shell of trapping.
The inwall of described upper bush body and the cylindrical shell of trapping has a circle metal protection protector respectively.
Be respectively equipped with a cloudy step of circle and circle balcony rank of mutual coupling on the joint face of described upper bush body and the cylindrical shell of trapping, described balcony rank penetrate in the cloudy step.
Adopted the heater of adjustable length of the present invention, by the spring heating collar is cast in the sleeve body, makes four faces of spring heating collar all can carry out heat exchange with sleeve body, and can not be out of shape because of intensification on the one hand, remain with the tight of sleeve body and contact, improve and add thermal effect; On the other hand, by sleeve body being divided into the upper bush body that is separated from each other and the cylindrical shell of trapping, compensate the spring heater that extends because of distortion, also can realize the heating to the nozzle of each length by suitable elongation.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure: 1-spring heating collar, 2-upper bush body, the 3-cylindrical shell of trapping, the cloudy step of 4-, 5-balcony rank, 6-metal protection protector.
The specific embodiment
As shown in Figure 1, the invention discloses a kind of heater of adjustable length, comprise a spring heating collar 1, in actual applications, usually the coiling of two ends of spring heating collar 1 is closeer, middle coiling is thinner, the innovative point of the heater of adjustable length of the present invention is that mainly being cast with one deck outside the described spring heating collar 1 wraps being of this spring heating collar 1 sleeve body cylindraceous, usually the material of casting sleeve body can be the preferable aluminium of heat conductivility or copper, and described sleeve body is divided into the upper bush body 2 that is separated from each other and the cylindrical shell 3 of trapping.Usually upper bush body 2 all adopts the same diameter, wall thickness with the cylindrical shell 3 of trapping, like this, two ends of closeer spring heating collar 1 of winding the line are wrapped by upper bush body 2 and the cylindrical shell 3 of trapping respectively, guarantee that the heat that spring heating collar 1 sends is greatly partly absorbed by upper bush body 2 and the cylindrical shell 3 of trapping, and the mid portion of the spring heating collar 1 that coiling is dredged, be used for connecting upper bush body 2 and the cylindrical shell 3 of trapping, guarantee the globality of sleeve body.
On the one hand because the inwall of the upper bush body 2 that casting forms and the cylindrical shell 3 of trapping is smooth inadequately; its circularity is not high yet; make that the applying degree of the inwall of upper bush body 2 and the cylindrical shell 3 of trapping and nozzle is not high; influence is to the heat transfer of nozzle; also be in order to protect spring heating collar 1 on the other hand; for this reason; the described upper bush body 2 of the heater of adjustable-length of the present invention and the inwall of the cylindrical shell 3 of trapping have a circle metal protection protector 6 respectively; the inwall of described metal protection protector 6 can adopt the metalworking mode to process in advance; the outer surface of its inwall and nozzle can be fitted tightly, and described metal protection protector 6 adopts tight fit to be connected with upper bush body 2 with the cylindrical shell 3 of trapping.
Another innovative point of the heater of adjustable length of the present invention is to be respectively equipped with on the joint face of described upper bush body 2 and the cylindrical shell 3 of trapping a cloudy step 4 of circle and circle balcony rank 5 of mutual coupling, and described balcony rank 5 penetrate in the cloudy step 4.Described cloudy step 4 refers to have the step-like depression of a circle at be connected with the cylindrical shell 3 of the trapping inwall of an end of upper bush body 2, the diameter of described cloudy step 4 is greater than the internal diameter of upper bush body 2, described balcony rank 5 refer to have the step-like depression of a circle at be connected with upper bush body 2 outer wall of an end of the cylindrical shell 3 of trapping, the diameter on described balcony rank 5 is less than the external diameter of the cylindrical shell 3 of trapping, simultaneously, the internal diameter of common cloudy step 4 is bigger slightly than the external diameter on balcony rank 5, can carry out axial movement along cloudy step 4 smoothly to make things convenient for balcony rank 5.In actual applications, both can adopt balcony rank 5 at the joint face of upper bush body 2, at the cloudy step 4 of joint face employing of the cylindrical shell 3 of trapping, also can adopt cloudy step 4 at the joint face of upper bush body 2, on the joint face employing balcony rank 5 of the cylindrical shell 3 of trapping.
