Description

Technical Field

[0001] The utility model relates to the technical field of plastic molds, in particular to a high-strength plastic mold. Background Art

[0002] Plastic molds are tools used in the plastic processing industry to match plastic molding machines and give plastic products complete configurations and precise dimensions. Due to the wide variety of plastics and processing methods, and the varying structures of plastic molding machines and plastic products, there are also many types and structures of plastic molds.

[0003] According to the search, Chinese patent literature, announcement number: CN218227447U, discloses a fast-discharging plastic mold. By setting a bottom plate, a lower mold, a support rod, a mounting plate, a hydraulic rod and an upper mold, the plastic product can be shaped after being placed into the interior of the plastic mold. By setting a socket, a plug rod, a top plate and a spring, when the upper mold is removed from the lower mold, the plastic product can be quickly and conveniently ejected from the interior of the lower mold. At the same time, by setting a threaded rotating rod, a rotating handle, a limiting rod, a movable frame, a threaded sliding rod, a rotating block, a clamping plate and a positioning rod, the plastic product can be quickly lifted, thereby making it more convenient to take the plastic product out of the interior of the plastic mold, saving time and energy, improving the practicality of the plastic mold, and accelerating the processing rate of the plastic product. However, during use, the product needs to be clamped and fixed by manually turning the handle, which is cumbersome and time-consuming, and increases the difficulty of manual operation. Long-term use can easily cause adhesion on the outside of the threaded rod, resulting in poor fluency in use. At the same time, there is heat on the surface of the product when it comes out, and it needs to be still and wait for cooling, which delays production efficiency. In the process of use, there is long-term friction between the upper and lower molds, which is easy to be damaged and reduces the service life, resulting in reduced mold strength.
