When the pipe orifice is connected to the side edge of the wax mold and is suspended outwards, the bolt which can be inserted into the bolt seat in a sliding manner is inserted into the hollow interior of the pipe orifice for butt joint, so that the bolt is inserted into the hollow interior of the pipe orifice, which is suspended outwards, of the wax mold for supporting; and the plug pin is supported and borne in the hollow inner part of the pipe orifice and is prevented from inward deformation, so that the problem of inward deformation of the wax mold of the pipe orifice caused by direct supporting from the lower part is solved.

Description

Technical Field

[0001] The utility model relates to a mold for controlling the deformation of a wax mold with a pipe orifice structure, belonging to the technical field of casting wax mold manufacturing. Background Art

[0002] When castings are produced, the shape of the casting needs to be constructed into a wax mold with wax material, and then a sand mold shell is made, and then molten metal liquid is poured into the sand mold shell. Therefore, the stability of the shape and size of the wax mold is one of the key steps to ensure the quality of the casting. For wax molds with nozzles hanging outward, the wax molds at the nozzles are prone to hanging and drooping and deformation when the tree is connected, so they need to be supported.

[0003] The current technology for supporting suspended wax models is disclosed in Chinese Patent Publication No. CN211360550U. Although the support block can be used to support the suspended part directly from below, the wax model of the pipe mouth is hollow inside, and direct support from below can easily cause the wax model of the pipe mouth to deform inward. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a tire mold for controlling the deformation of a wax mold with a pipe orifice structure.

[0005] The utility model is realized through the following technical solutions.

[0006] The utility model provides a tire mold for controlling the deformation of a wax mold with a pipe orifice structure, comprising:

[0007] The base as a load-bearing foundation;

[0008] A latch seat is fixedly connected to the outer periphery of the base, and a latch for inserting into the hollow interior of the pipe mouth of the wax model for support can be slidably inserted into the latch seat.

[0009] The base is fixedly connected with a boss that supports the steps on the inner surface of the wax mold.

[0010] The base is integrally and fixedly connected with the boss.

[0011] The bosses are multiple and spaced apart from each other, with the bosses being higher inside and lower outside.

[0012] The latch seats are a plurality of latch seats which are spaced apart on the outer circumference of the base in a circular array; each latch seat is provided with a latch through hole, and a latch can be slidably inserted into the latch through hole of the latch seat.

[0013] It also includes a wax mold placed on the base, wherein the inner step of the wax mold is in contact with the boss on the base for support; the wax mold has a pipe opening, and a pin is inserted and connected into the hollow interior of the pipe opening.

[0014] The beneficial effect of the utility model is that the step on the inner surface of the wax mold contacts the boss of the base to obtain support, and when the pipe mouth is connected to the side of the wax mold and hangs outward, the slidable inserted pin on the pin seat is inserted and docked with the hollow interior of the pipe mouth, so that the pin is inserted into the hollow interior of the pipe mouth hanging outward from the wax mold for support, and the pin is in the hollow interior of the pipe mouth to support and prevent inward deformation, which solves the problem that direct support from below may easily cause inward deformation of the wax mold of the pipe mouth.

[0018] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0019] like Figure 1 to Figure 2 shown.

[0020] The present invention discloses a mold for controlling the deformation of a wax mold with a nozzle structure, comprising:

[0021] The base 4 is used as a foundation for force bearing and installation. A boss 41 supporting the inner step of the wax mold 5 is integrally fixedly connected to the base 4. The boss 41 is a plurality of bosses 41 spaced apart from each other with the bosses being higher inside and lower outside.

[0022] The base 4 is welded or screwed with a bolt seat 2, which is a plurality of bolt seats 2 arranged in a circular array and spaced apart on the base 4. Each bolt seat 2 is provided with a bolt through hole, into which a bolt 3 can be slidably inserted, and the bolt is inserted through the bolt through hole of the bolt seat 2 and then inserted into the hollow interior of the pipe opening 51 hanging outward from the wax model 5.

[0023] The latch through holes of the plurality of latch seats 2 are slidably inserted into the latch pins 3 to insert and support the plurality of pipe openings 51 hanging outward from the wax model 5 .

[0024] After the main body of the wax model 5 is connected, it is placed on the base 4. The inner step of the wax model 5 contacts the boss 41 of the base 4 for support. When the pipe mouth 51 is connected to the side of the wax model 5 and hangs outward, the slidably inserted latch 3 on the latch seat 2 is inserted and docked with the hollow interior of the pipe mouth 51, so that the latch 3 is inserted into the hollow interior of the pipe mouth 51 hanging outward from the wax model 5 for support. The latch 3 is in the hollow interior of the pipe mouth 51 to support and prevent inward deformation, which solves the problem that direct support from below easily causes inward deformation of the wax model of the pipe mouth.
