Description

Technical Field

[0001] This utility model relates to the technical field of motor shafts, and in particular to a special forming mold for thread protectors. Background Technology

[0002] Thread protectors primarily protect threads from damage caused by friction, collisions, or other external forces during production and transfer. Thread protectors are typically made of plastic and are generally produced through injection molding. Molten material is poured into a mold, and the mold is opened after the material cools and solidifies before the protector is removed. However, existing thread protector molds require a 6-8 second settling period for initial cooling and solidification, which is time-consuming. Therefore, this application proposes a mold that eliminates the need for a settling period to accelerate the molding of thread protectors. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a special forming mold for thread protectors, so as to solve the problem that the molds for thread protectors in the prior art described in the background art lack rapid pre-forming function.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a special forming mold for thread protectors, comprising...

[0005] Base plate;

[0006] The first mold is set on the base plate, and the first mold has a heat absorption cavity inside;

[0007] The liquid inlet pipe and liquid outlet pipe are respectively installed on the base plate and connected to the heat absorption chamber;

[0008] The second and third molds are combined to form a threaded cavity. The opening end of the threaded cavity is provided with an annular cavity. The first mold passes through the annular cavity and extends into the threaded cavity.

[0009] The feed pipe is installed on the second mold and communicates with the threaded cavity;

[0010] The discharge pipe is installed on the third mold and connected to the threaded cavity.

[0011] Preferably, the base plate is provided with a plurality of positioning posts arranged in a ring around the first mold. The lower end of the outer wall of the second mold and the lower end of the outer wall of the third mold are respectively provided with a first positioning plate and a second positioning plate. The first positioning plate and the second positioning plate are respectively provided with positioning holes corresponding to the positions of the positioning posts. The positioning posts slide into the positioning holes at the corresponding positions.

[0012] Preferably, the outer walls of the second mold and the third mold are respectively provided with mounting plates.

[0013] The beneficial effects of adopting the above technical solutions are:

[0014] This application achieves the effect of cooling and absorbing heat on the first mold by opening a heat-absorbing cavity in the first mold, pouring a heat-absorbing medium into the heat-absorbing cavity through the liquid inlet pipe, and then discharging the heat-absorbing medium through the liquid outlet pipe. This can absorb the heat energy of the product and improve the efficiency of shaping. Attached Figure Description

[0019] The components include: base plate 10, first mold 20, heat absorption chamber 30, liquid inlet pipe 31, liquid outlet pipe 32, second mold 40, feed pipe 41, first positioning plate 42, third mold 50, discharge pipe 51, second positioning plate 52, positioning hole 60, positioning post 61, threaded cavity 70, annular cavity 71, and mounting plate 80. Detailed Implementation

[0020] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-4 In this first embodiment, the special forming mold for the thread protector includes...

[0022] Base plate 10;

[0023] The first mold 20 is disposed on the base plate 10, and the first mold 20 is provided with a heat absorption cavity 30.

[0024] The liquid inlet pipe 31 and the liquid outlet pipe 32 are respectively installed on the base plate 10 and connected to the heat absorption chamber 30;

[0025] The second mold 40 and the third mold 50 are combined to form a threaded cavity 70. The opening end of the threaded cavity 70 is provided with an annular cavity 71. The first mold 20 passes through the annular cavity 71 and extends into the threaded cavity 70.

[0026] The feed pipe 41 is mounted on the second mold 40 and communicates with the threaded cavity 70;

[0027] The discharge pipe 51 is installed on the third mold 50 and communicates with the threaded cavity 70.

[0028] This embodiment is implemented as follows:

[0029] This application uses the threaded cavity 70 and annular cavity 71 formed by the second mold 40, the third mold 50, and the first mold 20 to form the product mold cavity. Then, raw material is injected into the threaded cavity 70 through the feed pipe 41. When the threaded cavity 70 and annular cavity 71 are full of raw material, the raw material will flow out from the discharge pipe 51, and then the feed pipe 41 will stop feeding. During this process, when the raw material just submerges the outer wall of the first mold 20, the liquid inlet pipe 31 injects a medium into the heat absorption cavity 30 to absorb heat. The heat-absorbing medium flows out from the liquid outlet pipe 32. This can quickly absorb heat from the first mold 20, so that the first mold 20 can quickly absorb the heat energy of the product, allowing the product to be pre-cooled quickly and effectively reducing the pre-cooling time.

[0030] Please see Figure 1 , 2 3. The base plate 10 is provided with a number of positioning posts 61 arranged in a ring around the first mold 20. The lower end of the outer wall of the second mold 40 and the lower end of the outer wall of the third mold 50 are respectively provided with a first positioning plate 42 and a second positioning plate 52. The first positioning plate 42 and the second positioning plate 52 are respectively provided with positioning holes 60 corresponding to the positions of the positioning posts 61. The positioning posts 61 slide into the corresponding positioning holes 60.

[0031] The positioning holes 60 on the first positioning plate 42 and the second positioning plate 52 of this application can be used for the positioning pin 61 to pass through, which makes the positional relationship of the first mold 20, the second mold 40 and the third mold 50 more stable.

[0032] Please see Figure 1 , 2 3. Mounting plates 80 are respectively provided on the outer walls of the second mold 40 and the third mold 50.

[0033] The second mold 40 and the third mold 50 in this application are connected to an external mobile device via a mounting plate 80.

[0034] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
