Description

Technical Field

[0001] This utility model relates to the field of mold production, specifically a surface polishing machine for mold production. Background Technology

[0002] After molding, molds may have defects such as unevenness, burrs, and tool marks on their surface, which can affect the mold's demolding performance, product molding quality, and mold lifespan. For example, in injection molds, an uneven surface can lead to scratches and tears on the surface of plastic products. Therefore, a surface polishing machine is needed to finely polish the mold surface to achieve the required surface roughness and smoothness. Thus, a surface polishing machine for mold production is required.

[0003] An existing surface polishing machine for mold production has limitations. It does not allow for quick and convenient replacement of the polishing blocks, nor does it improve the safety and stability of the operation when polishing molds. Therefore, there is an urgent need for a surface polishing machine for mold production. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a surface polishing machine for mold production, so as to solve the problems that existing surface polishing machines for mold production cannot quickly and conveniently replace the polishing blocks, and cannot improve the safety and stability of operation when polishing molds.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a surface polishing machine for mold production, comprising a protective frame, a threaded hole at the upper end of the protective frame, a protective cover installed at the upper end of the protective frame, a threaded rod installed at one end of the protective cover, a heat dissipation hole at the upper end of the protective cover, an auxiliary handle installed at the upper end of the protective cover, a control handle installed at one end of the protective cover, a slot at the upper end of the control handle, a strap installed at the upper end of the slot, a drive motor installed inside the protective cover, a fixing hole at the lower end of the drive motor, a polishing block installed at the lower end of the drive motor, a fixing rod installed at the upper end of the polishing block, and nuts installed at both ends of the fixing rod.

[0006] Preferably, the protective cover is threadedly connected to the protective frame through a threaded hole, and the protective cover fits tightly against the protective frame.

[0007] Preferably, the auxiliary grip is engaged with the protective cover, and the auxiliary grip is configured in an "I" shape.

[0008] Preferably, the strap is connected to the control arm via a slot, and the strap is made of elastic cord.

[0009] Preferably, the drive motor is welded to the protective frame and threaded to the grinding block.

[0010] Preferably, the grinding block is threadedly connected to the drive motor via a fixing rod, and the grinding block forms a rotating structure with the protective frame via the drive motor.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model features a protective frame, a protective cover, an auxiliary handle, a drive motor, and a grinding block. The grinding block installed in the device is connected by a fixing rod, which facilitates disassembly and replacement. After replacing the grinding block, the grinding efficiency of the grinding machine on the outer surface of the mold can be maintained.

[0013] This utility model, through the setting of a protective frame, protective cover, auxiliary grip and control handle, can protect the drive motor through the protective cover installed in the device, and through the two sets of installed auxiliary grips and control handles, can make the control more stable when the grinder is used.

[0014] This utility model features a protective frame, an auxiliary grip, a control handle, and a strap. The control handle is fitted with a rubber strap at one end, allowing the control handle to be connected to the hand when using the grinder. This prevents the handle from slipping out of the hand and improves the safety of using the grinder. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The embodiments of this utility model will be described below based on its overall structure.

[0022] Please see Figure 1-4 A surface polishing machine for mold production includes a protective frame 1, a threaded hole 2 at the upper end of the protective frame 1, a protective cover 3 mounted on the upper end of the protective frame 1, a threaded rod 4 mounted on one end of the protective cover 3, and a heat dissipation hole 5 at the upper end of the protective cover 3. The protective cover 3 is threadedly connected to the protective frame 1 through the threaded hole 2, and the protective cover 3 fits tightly against the protective frame 1. The protective cover 3 can be opened through the threaded rod 4 to allow inspection and maintenance of the drive motor 10 in the device. An auxiliary handle 6 is mounted on the upper end of the protective cover 3, and a control handle 7 is mounted on one end of the protective cover 3. A slot 8 is opened on the upper end of the control handle 7, and a strap 9 is mounted on the upper end of the slot 8. The auxiliary handle 6 is engaged with the protective cover 3, and the auxiliary handle 6 has an "I" shaped structure. The auxiliary grip 6 and control handle 7 allow for two-handed control during use, ensuring greater stability during polishing. The strap 9 and control handle 7 provide comfortable hand positioning and prevent falls. The protective cover 3 houses a drive motor 10 with a fixing hole 11 at its lower end. A polishing block 12 is mounted on the lower end of the drive motor 10, and a fixing rod 14 is mounted on the upper end of the polishing block 12. Nuts 13 are installed at both ends of the fixing rod 14. The polishing block 12 is threadedly connected to the drive motor 10 via the fixing rod 14, and the polishing block 12 forms a rotating structure with the protective frame 1 via the drive motor 10. The polishing block 12 installed in the device can be quickly replaced via the fixing rod 14, maintaining polishing efficiency.

[0023] Working principle: In use, the grinding block 12 is connected to the drive motor 10 via the fixing rod 14 as needed, and the connection is kept tight by the nut 13. The power of the device is turned on, and the auxiliary handle 6 and the control handle 7 are controlled by both hands respectively. The hands on the control handle 7 can be wrapped with the elastic strap 9. After wrapping, the surface of the mold can be ground by the operation of the drive motor 10. If the grinding efficiency of the grinding block 12 decreases during the grinding process, the power can be turned off, and the grinding block 12 can be replaced by disassembling the fixing rod 14 to continue the grinding operation. After the grinding operation of the mold is completed, the grinding machine needs to be maintained. The protective cover 3 can be separated from the protective frame 1 by turning the threaded rod 4 to perform routine inspection and maintenance of the drive motor 10. This completes the use of the device. The contents not described in detail in this manual are existing technologies known to those skilled in the art.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
