Abstract

The utility model discloses a paraffin-filling gun. The paraffin-filling gun comprises a barrel body with two ends sealed, wherein an inner barrel is arranged in the barrel body, an annular hollow cavity is formed between the barrel body and the inner barrel, the top portion of the inner barrel is fixed with the inner wall of the barrel body in a welded and sealed mode, and a nozzle which extends out of a lower cover of the barrel body is welded at the lower end of the inner barrel in a sealed mode. A spring is arranged inside the inner barrel, the lower end of the spring abuts against a hopper segment of a wall of the inner barrel, and a push rod extends into the inner barrel. The upper portion of the outer wall of the push rod and middle portion of the outer wall of the push rod are respectively provided with a thread and a convex plate, wherein the convex plate presses the upper end of the spring. The lower end of the push rod abuts against a center hole of the nozzle when paraffin is not filled. A water outlet pipe and a water inlet pipe both for hot water are respectively arranged on the upper portion and the lower portion of the outer wall of the barrel body, wherein the water inlet pipe and the water outlet pipe are communicated with the annular cavity. A paraffin-filling pipe is arranged at the center of the water inlet pipe, and the outlet end of the paraffin-filling pipe is communicated with the inner barrel. The paraffin-filling gun is reasonable in structural design. Due to the facts that the paraffin-filling pipe is additionally arranged on the water inlet pipe, and the hot water is recycled and reused through cooperation of the water inlet pipe and the hollow cavity, the paraffin-filling gun is enabled to maintain a stationary temperature in a paraffin-filling process, the paraffin is maintained to be in a liquid state all the time, and phenomenon of blockage is avoided.

Description

A kind of casting rifle

Technical field:

The utility model relates to the wax process technology, relates in particular to a kind of 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 casting rifle, and reasonable in design can guarantee for a long time that the phenomenon that shutoff can not sprayed wax appears in casting Guan Buhui.

The technical solution of the utility model is as follows:

The 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, be provided with spring in the inner core, withstand on the funnel section of described inner tube wall the spring lower end, have push rod to extend in the inner core, push rod outer wall top and middle part are respectively equipped with screw thread, boss, boss are pushed down and described spring upper end, the centre bore of described nozzle is withstood in push rod lower end when not casting, described cylinder body outer wall is respectively equipped with up and down 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 casting rifle 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:

The 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, be provided with spring 5 in the inner core 2, withstand on the funnel section of inner core 2 walls spring 5 lower ends, have push rod 6 to extend in the inner core 2, push rod 6 outer wall tops and middle part are respectively equipped with screw thread 7, boss 8, boss 8 are pushed down and spring 5 upper ends, the centre bore 9 of nozzle is withstood in push rod 6 lower end when not casting, cylindrical shell 1 outer wall is respectively equipped with up and down the hot water outlet pipe 10 with toroidal cavity 3 UNICOMs, water inlet pipe 11, water inlet pipe 11 centers are provided with casting pipe 12, casting pipe 12 ports of export and inner core 2 UNICOMs.

Be provided with shell body 13 outside the cylindrical shell 1, be provided with the heat-insulation layer 14 of insulation material between shell body 13 and the cylindrical shell 1.
