Description

Technical Field

[0001] The utility model relates to the technical field of wax mold processing, in particular to a turbocharger turbine compression mold. Background Art

[0002] There are two main wax injection methods for the existing supercharger turbine wax mold pressing mold, bottom injection and top injection. Among them, the bottom injection wax injection method and process often leave a long section of wax rod remaining on the product wax parts. 1. The removed product wax parts need to be cut off with scissors to remove the excess wax rod. 2. If the wax rod breaks in the mold (commonly known as "broken core"), the wax rod broken in the mold must be taken out, otherwise the wax rod will block the wax injection channel, and the next mold cannot be injected with wax, resulting in the inability to carry out wax pressing production continuously. This is the technical problem to be solved by this application.

[0003] For this reason, we propose a supercharger turbine compression mold. Utility Model Content

[0004] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a supercharger turbine compression mold, so that the wax parts have no wax rod residue and will not produce core breakage, reducing the amount of product wax, saving costs and improving wax pressing efficiency.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A supercharger turbine die, comprising:

[0007] A mold assembly having a vertically arranged mold cavity therein;

[0008] A wax piece, which is connected to the upper part of the mold assembly through a connecting piece, and a shaping pipe for wax injection is arranged in the wax piece; and,

[0009] The hot runner system is arranged in the mold cavity and is used to provide hot melt wax to the wax part. The hot runner system structure includes:

[0010] A hot nozzle that has wax injected into one end and is able to heat the wax and eject it out the other end;

[0011] A connecting sleeve is sleeved on the periphery of the hot nozzle to separate the mold components, and the connecting sleeve is connected to the molding pipe;

[0012] The heat transfer tube is provided with an outlet of a hot nozzle and is connected to a shaped pipeline. The upper end of the heat transfer tube is conical, and a plurality of through holes are opened on the conical surface.

[0013] Furthermore, the mold assembly includes an upper mold and a lower mold stacked up and down, and cooling water channels are provided in both the upper mold and the lower mold.

[0014] Furthermore, the mold assembly is connected with a plug connector for controlling the temperature of the hot runner system.

[0015] Furthermore, a vertically arranged flow channel is provided in the hot nozzle, and a heating coil is wound around the hot nozzle.

[0016] Furthermore, the opening of the hot nozzle is sunken and provided with a step hole, and the heat transfer tube is engaged in the step hole and fixed by a locking member.

[0017] Furthermore, the lower end of the connecting sleeve is open and covers the hot nozzle, and the connecting sleeve presses the locking piece and reserves a through hole for the heat transfer pipe to pass through.

[0018] Furthermore, the lower end of the hot nozzle is connected to a base, and a wax injection port corresponding to the hot nozzle is opened on the base, and heat insulation sheets are connected to the lower end of the base and the upper end surface of the hot nozzle to separate the mold assembly.

[0019] Furthermore, an internal skeleton is provided inside the wax piece to support the wax piece.

[0020] Furthermore, the shaped pipe and the connecting sleeve are integrally formed.

[0021] Furthermore, the connecting piece is connected to the upper mold, and a connecting hole is provided on the connecting piece which penetrates axially.

[0022] The beneficial effects of the utility model are as follows:

[0023] The utility model has a compact and reasonable structure and is easy to operate. The temperature of the hot nozzle heating is controlled to ensure that the entire wax injection flow channel is at a relatively high temperature and is controllable, so that the wax in the entire flow channel from the nozzle outlet of the wax pressing machine to the hot nozzle and the gate end of the wax piece is kept in a molten state. When the wax in the mold cavity is cooled and the wax in the wax piece is solidified, the wax in the wax injection flow channel B is always kept in a molten state. In this way, the wax piece taken out has no wax rod residue and will not have the phenomenon of core breakage, thereby reducing the amount of wax used in the product, saving costs and improving the wax pressing efficiency.

[0024] At the same time, the utility model also has the following advantages:

[0025] (1) The connecting sleeve in this embodiment is sleeved on the periphery of the hot nozzle to separate the mold assembly, and the connecting sleeve is connected to the shaping pipe, and a certain space is reserved between the connecting sleeve and the hot nozzle to prevent heat from being transferred into the mold assembly and affecting the subsequent cooling effect.

[0026] (2) The heat transfer tube in this embodiment is provided with a hot nozzle outlet and is connected to the shaping pipe. The upper end of the heat transfer tube is conical, and a plurality of through holes are opened on the conical surface. The molten wax will enter the shaping pipe through the through holes on the conical surface. After the wax is cooled and fixed, it will become one with the wax piece.

[0027] (3) The conical convex shaping pipe in this embodiment facilitates demolding of the wax rod after cooling, and the contact area between the conical heat transfer pipe and the wax rod decreases from bottom to top, thereby preventing the heat in the heat transfer pipe from affecting the cooling and solidification of the wax rod, and facilitating demolding.

[0028] (4) In this embodiment, the opening of the hot nozzle is sunken and provided with a stepped hole. The heat transfer tube is engaged in the stepped hole and fixed by a locking member, thereby improving the overall connection effect and preventing molten wax from remaining in the gap.

[0038] The specific implementation of the utility model is described below in conjunction with the accompanying drawings.

[0039] like Figure 1As shown, the present embodiment discloses a supercharger turbine compression mold, including a mold assembly, a wax part 300, a hot runner system 600, a hot nozzle 602, a connecting sleeve 603 and a heat transfer pipe 605, and the temperature of the hot nozzle 602 heating is controlled to ensure that the entire wax injection flow channel b is at a relatively high temperature and is controllable, so that the wax in the entire flow channel from the nozzle outlet of the wax injection machine to the hot nozzle 602 and the gate end of the wax part 300 is kept in a molten state. When the wax in the mold cavity is cooled, since the hot nozzle 602 is equipped with a heat insulation sheet 604, physical insulation is performed between the mold assembly, and the hot nozzle 602 will not be reduced as the temperature of the mold assembly is reduced (the mold assembly is connected with cooling water), so that the wax in the wax injection flow channel b is always kept in a molten state, and will not be taken out with the wax part gradually cooled in the shaping pipeline 302. The wax part 300 taken out in this way has no wax rod residue, and will not produce the phenomenon of broken core, which reduces the amount of product wax, saves costs, and improves the efficiency of wax pressing.

[0040] The following is a detailed description of the specific structure:

[0041] In this embodiment, Figure 1 and Figure 2 As shown, the mold assembly has a vertically arranged mold cavity therein, and the mold assembly includes an upper mold 100 and a lower mold 200 stacked up and down, and cooling water channels are provided in both the upper mold 100 and the lower mold 200 to facilitate the introduction of cooling water for overall cooling.

[0042] The wax piece 300 is connected to the upper part of the mold assembly through the connecting piece 400, and a shaping pipe 302 for wax injection is arranged in the wax piece 300; the upper end of the shaping pipe 302 abuts against the wax piece 300 and forms a wax column in the wax piece 300, and it is the wax column that affects and determines the processing difficulty of the wax piece 300;

[0043] like Figure 2 and Figure 3 As shown, the connecting piece 400 in this embodiment is connected to the upper mold 100, and an axially penetrating connecting hole is provided on the connecting piece 400 to facilitate the installation of the wax piece 300 and the molding pipe 302.

[0044] like Figure 2 , Figure 3 and Figure 5 As shown, an inner frame 301 is further provided in the wax piece 300 in this embodiment for supporting the wax piece 300 and also providing support for the shaping pipe 302 . A channel for the shaping pipe 302 is reserved on the inner frame 301 .

[0045] The biggest highlight of this embodiment is the hot runner system 600. Figure 2-Figure 5As shown, the hot runner system 600 is arranged in the mold cavity and is used to provide hot-melt wax to the wax part 300. The hot runner system 600 structure includes a hot nozzle 602, a connecting sleeve 603 and a heat transfer pipe 605, which heats the wax to make the wax in a molten state and avoid the formation of wax rods in the mold cavity.

[0046] In this embodiment, the hot nozzle 602 has wax injected into its lower end and is capable of heating the wax and spraying it out from the other upper end;

[0047] The connecting sleeve 603 in this embodiment is sleeved on the outer periphery of the hot nozzle 602 to separate the mold assembly, and the connecting sleeve 603 is connected to the shaping pipe 302, and a certain space is reserved between the connecting sleeve 603 and the hot nozzle 602 to prevent heat from being transferred into the mold assembly and affecting the subsequent cooling effect;

[0048] The heat transfer tube 605 in this embodiment is provided with an outlet of a hot nozzle 602 and is connected to the shaping pipe 302. The upper end of the heat transfer tube 605 is conical, and a plurality of through holes 6051 are opened on the conical surface. The molten wax will enter the shaping pipe 302 through the through holes 6051 on the conical surface, and after the wax is cooled and fixed, it will form a whole with the wax piece 300.

[0049] In this embodiment, from Figure 4 As shown, the conical convex molding pipe 302 facilitates demoulding of the cooled wax rod, and the contact area between the conical heat transfer pipe 605 and the wax rod decreases from bottom to top, preventing the heat in the heat transfer pipe 605 from affecting the cooling and solidification of the wax rod, thereby facilitating demoulding.

[0050] The mold assembly in this embodiment is connected with a plug connector 500 . In this embodiment, the plug connector 500 is connected to a temperature control box for controlling the temperature of the hot runner system 600 .

[0051] In this embodiment, a vertically arranged wax injection channel b is provided in the hot nozzle 602, and a heating coil is wound around the hot nozzle 602. At the same time, a certain space is reserved between the connecting sleeve 603 and the hot nozzle 602, so that the heating coil can be arranged conveniently and the uniformity of heating can be improved.

[0052] In this embodiment, the opening of the hot nozzle 602 is sunken and has a stepped hole. The heat transfer tube 605 is engaged in the stepped hole and fixed by a locking member 606, thereby improving the overall connection effect and preventing molten wax from remaining in the gap.

[0053] In this embodiment, the lower end of the connecting sleeve 603 is open and covers the hot nozzle 602. The connecting sleeve 603 presses the locking piece 606 and reserves a through hole for the heat transfer pipe 605 to pass through, so as to better isolate the hot nozzle 602 and the mold assembly to avoid heat interference.

[0054] In this embodiment, the lower end of the hot nozzle 602 is connected to the base 601, and a wax injection port corresponding to the hot nozzle 602 is opened on the base 601, and a heat insulation sheet 604 is connected to the lower end of the base 601 and the upper end surface of the hot nozzle 602 to separate the mold components and improve the heat insulation effect.

[0055] The shaping pipe 302 and the connecting sleeve 603 in this embodiment are integrally formed, which reduces seams and thus prevents the molten wax from leaking out, thereby improving the utilization rate of the wax.

[0056] The specific processing method of this embodiment is as follows:

[0057] 1. This technology is to take out the original wax injection insert of the mold assembly and install the wax injection insert with the hot nozzle 602;

[0058] 2. When in use, energize the heating coil on the hot nozzle 602 and set the temperature of the temperature control box to 59°C required for the normal wax pressing process;

[0059] 3. After about 10 seconds of heating, when the temperature reaches 59°C, start pressing the wax normally;

[0060] 4. After the wax pressing is completed, take out the wax model.

[0061] In this embodiment, the original mold can be formed by adding a hot runner mechanism, which has the following effects:

[0062] 1. Eliminate wax rod residue, reduce product wax usage, and reduce production costs. It is estimated that about 100,000 yuan of wax can be saved each year;

[0063] 2. The core breakage phenomenon is eliminated, and there is no wax rod residue in the wax injection channel, so wax pressing production can be carried out continuously. The wax pressing efficiency is increased from the original 400 pieces / shift to 420 pieces / shift, and the shift output is increased by 5%. It has strong practicality and is easy to promote and use.
