Description

Technical Field

[0001] This utility model relates to the field of thread mold technology, specifically to a novel cooling mechanism for a mold used in the production of internal threads. Background Technology

[0002] The existing cooling mechanism for internal thread production molds features a fixed mold core with a water channel in the center. The movable mold core, which needs to be rotated and ejected, is fitted onto the fixed mold core. This design ensures the central cooling water channel remains sealed during product ejection and provides some cooling to the rotating mold core, thus cooling the product. However, because the outer walls of the fixed and movable mold cores experience dry friction, debris and other foreign objects can accumulate between the two mold cores during ejection. Over time, this can cause jamming, preventing the movable mold core from rotating and impacting production, requiring regular maintenance. Furthermore, the central water channel is relatively far from the internal thread due to the separation of the fixed and movable mold cores, resulting in uneven cooling. Utility Model Content

[0003] The purpose of this utility model is to provide a novel cooling mechanism for a mold used in the production of internal threads. The mold core is an integral piece, which avoids the mold core from getting stuck and provides more uniform cooling, thus solving the problem of cooling water channel design for internal thread production molds.

[0004] Technical Solution: This utility model provides a novel cooling mechanism for a mold used in the production of internal threads, comprising: a fixed module, a rotating mold core, a support assembly, and a rotary joint. The fixed module includes a base plate, a support plate, and a support platform, which are stacked sequentially from bottom to top, with a set of through holes passing through the three components in the middle. The rotating mold core is disposed within the through holes of the fixed module, and a first bearing and a second bearing are mounted on the outside of the rotating mold core. The first bearing is located below the through hole in the support plate, and the second bearing is located below the through hole in the base plate. Their outer diameters are fixed to the support plate and the base plate, respectively, to prevent the rotating mold core from getting stuck. The support assembly is disposed below the fixed module. The rotary joint is disposed within the support assembly and connected to the lower interface of the rotating mold core. A water inlet is disposed below the rotary joint, and the water inlet is connected to a water inlet pipe, the other end of which passes through the support assembly.

[0005] Furthermore, in the novel cooling mechanism of the aforementioned mold for producing internal threads, a water injection cavity is provided inside the rotating mold core.

[0006] Furthermore, in the novel cooling mechanism of the aforementioned internal thread production mold, a water injection pipe is provided inside the rotary joint.

[0007] Furthermore, in the novel cooling mechanism of the aforementioned mold for producing internal threads, one end of the water injection pipe is connected to the water injection cavity, and the other end is connected to the water inlet pipe.

[0008] Furthermore, in the novel cooling mechanism of the aforementioned mold for producing internal threads, a water outlet is provided below the rotary joint, the water outlet is above the water inlet, and the water outlet is connected to a water outlet pipe.

[0009] Furthermore, in the novel cooling mechanism of the aforementioned mold for producing internal threads, the upper end of the rotating mold core passes above the support platform, and the outer side of the upper end of the rotating mold core is the internal thread product. The internal thread product is cooled by introducing cooling water into the rotating mold core.

[0010] Furthermore, in the novel cooling mechanism of the aforementioned mold for producing internal threads, the support assembly includes a mold foot and a clamping plate. The mold foot is vertically disposed on the outer side below the base plate, and a water supply pipe passes through a through hole in the middle of the mold foot. The clamping plate is disposed below the mold foot.

[0011] As can be seen from the above technical solution, this utility model has the following beneficial effects: The novel cooling mechanism of the mold for producing internal threads described in this utility model is designed with a rotating mold core. The rotating mold core is equipped with bearings, which can effectively ensure that it will not get stuck during long-term rotation. The rotating joint is connected to the rotating mold core, and a water channel is set in the rotating mold core. This ensures that the sealing of the central cooling water channel is not affected when the product is rotated out, and facilitates the rotation and removal of the product, making the production process smoother. It can also improve the surface finish of the parts, thereby improving the overall quality of the parts and enhancing the competitiveness of the products in the market. Attached Figure Description
