Abstract

The utility model discloses a heat preservation wax injection gun which comprises a cylinder body. Two ends of the cylinder body are sealed. An internal cylinder is arranged in the cylinder body. An annular cavity is formed between the cylinder body and the internal cylinder. The top of the internal cylinder is welded, sealed and fixed with the inner wall of the cylinder body. A spray nozzle which extends out of a lower cover of the cylinder body is welded at the lower end of the internal cylinder in a sealed mode. The contact position between the spray nozzle and the lower end of the internal cylinder is funnel-shaped. An ejector rod is screwed and inserted into the internal cylinder. At the time of not injecting wax, the lower end of the ejector rod is pressed against a center hole of the spray nozzle. A hot water outlet pipe and a hot water inlet pipe are respectively arranged on the upper side and the lower side of the outer wall of the cylinder body and respectively communicated with the annular cavity. A wax injection pipe is arranged at the center of the hot water inlet pipe. An outlet end of the wax injection pipe is communicated with the internal cylinder. The heat preservation wax injection gun is reasonable in structural design. The wax injection pipe is additionally arranged in the hot water inlet pipe and coordinates with the annular cavity to carry out cyclic utilization to hot water so that the wax injection gun can maintain the constant temperature in the process of injecting the wax, and the wax is in a liquid state all along. Consequently, the phenomenon of blocking can not occur.

Description

A kind of insulation casting rifle

Technical field:

The utility model relates to the wax process technology, relates in particular to a kind of insulation casting rifle.

Background technology:

The freezing point of wax is all higher, between 38～90 ℃.Iodine number lower (1～15) illustrates that degree of unsaturation is lower than neutral fat.Wax in a narrow sense refers to lipidol and the higher oily mater of fusing point of aliphatic acid, monovalence or divalence usually; Broadly typically refer to the materials such as grease with some similar proterties.

Definition for " wax " under different occasions is also distinguished to some extent.But in a broad sense, normally easily liquefaction or gasification after referring under certain normal temperature that plant, animal or mineral etc. produce for solid, heating of wax, easily burning, water insoluble, material with certain lubrication.

For the wax of liquid state is transported to an other end from an end of longer distance from pipe, carry out spray through the casting rifle, need to keep stationary temperature, otherwise wax can solidify in pipe, so that the shutoff of casting rifle can not sprayed wax, how designing a kind of casting rifle with insulation effect is the task of top priority.

The utility model content:

The purpose of this utility model provides a kind of insulation casting rifle, and reasonable in design can guarantee for a long time that the casting rifle the phenomenon that shutoff can not sprayed wax can not occur.

The technical solution of the utility model is as follows:

Insulation casting rifle, it is characterized in that: comprise sealed at both ends cylindrical shell, be provided with inner core in the cylindrical shell, form toroidal cavity between cylindrical shell and the inner core, the inwall welded seal of the top of inner core and cylindrical shell is fixed, the seal weld of inner core lower end is connected to the nozzle that stretches out the cylindrical shell lower cover, nozzle and contact position, inner core lower end funneling, there is push rod to screw and extend in the inner core, the centre bore of nozzle is withstood in push rod lower end when not casting, described cylinder body outer wall upper and lower sides is respectively equipped with the hot water outlet pipe with toroidal cavity UNICOM, water inlet pipe, the water inlet pipe center is provided with the casting pipe, the casting pipe port of export and described inner core UNICOM.

Described insulation casting rifle, it is characterized in that: described cylindrical shell is provided with shell body outward, is provided with the heat-insulation layer of insulation material between shell body and the cylindrical shell.

The utility model has the advantages that:

The utility model reasonable in design by setting up the casting pipe in the water inlet pipe, cooperates toroidal cavity that hot water is carried out recycling, so that the casting rifle carries out keeping stationary temperature in the process of casting, wax is in liquid state all the time, the shutoff phenomenon can not occur.

Description of drawings:

Fig. 1 is structural representation of the present utility model.

The specific embodiment:

Referring to Fig. 1:

Insulation casting rifle, comprise sealed at both ends cylindrical shell 1, be provided with inner core 2 in the cylindrical shell 1, form toroidal cavity 3 between cylindrical shell 1 and the inner core 2, the inwall welded seal of the top of inner core 2 and cylindrical shell 1 is fixed, inner core 2 lower end seal welds are connected to the nozzle 4 that stretches out cylindrical shell 1 lower cover, nozzle 4 and contact position, inner core 2 lower end funneling, there is push rod 5 to screw and extend in the inner core 2, the centre bore 6 of nozzle is withstood in push rod 5 lower end when not casting, cylindrical shell 1 outer wall upper and lower sides is respectively equipped with the hot water outlet pipe 7 with toroidal cavity 3 UNICOMs, water inlet pipe 8, water inlet pipe 8 centers are provided with casting pipe 9, casting pipe 9 ports of export and inner core 1 UNICOM.

Be provided with shell body 10 outside the cylindrical shell 1, be provided with the heat-insulation layer 11 of insulation material between shell body 10 and the cylindrical shell 2.
