Abstract
Description
Technical Field
[0001] The utility model belongs to the field of mold equipment, and particularly relates to a plastic mold with a protective structure. Background Art
[0002] A plastic mold is a tool used for molding plastic products, usually consisting of two upper and lower templates and a core in the middle. The plastic material is injected into the mold, molded by heating or other means, and then cooled, demolded, and other processes to obtain the desired plastic product. In actual use, the plastic mold may be subjected to a large impact force during use without a buffer protection structure, causing the mold to be easily worn, deformed, or even broken. This will shorten the service life of the mold and increase production costs. This is because there is a lack of protective parts. The lack of protective parts will not only lead to the above problems, but also in the absence of a buffer protection structure, the plastic mold may need to be frequently repaired and replaced, which will lead to reduced production efficiency and increased production costs. Therefore, it is necessary to propose a new structure to solve the above technical problems. Utility Model Content

The upper mold assembly 400 includes an upper mold plate 410, an upper mold body 440, a buffer column 420 and a limit block 430. The upper mold body 440 is installed on the lower surface of the upper mold plate 410, and the buffer column 420 and the limit block 430 are installed on the lower surface of the upper mold body 440.
[0023] See also Figures 1 to 3 As the first embodiment of the utility model: the base assembly 100 includes a base plate 110, a pad 130, a limit plate 120 and a shock absorbing assembly. The pad 130 is installed on the upper surface of the base plate 110, and a shock absorbing assembly is installed at four corners of the upper side surface of the pad 130, and the four shock absorbing assemblies have the same structure;
[0024] The shock absorbing assembly includes a shock absorbing column 140 and a shock absorbing spring 141. One end of the shock absorbing column 140 away from the pad 130 penetrates the surface of the lower template 310. The outer surface of the shock absorbing column 140 is provided with a shock absorbing spring 141. The upper end of the shock absorbing spring 141 is connected to the lower surface of the lower template 310, and the lower end of the shock absorbing spring 141 is connected to the upper surface of the pad 130.
[0025] A limiting plate 120 is symmetrically mounted on the left and right surfaces of the pad 130, a sponge pad is glued to the upper surface of the limiting plate 120, and a gap is provided between the upper surface of the limiting plate 120 and the lower surface of the lower template 310;
[0026] A lower mold body 320 is installed at the center of the upper surface of the lower mold plate 310.

The stop block 1 330 and the stop block 2 430 are complementary structures.
[0027] A support rod 220 is installed at each of the four corners of the upper surface of the base plate 110.

A buffer column 420 is installed at each of the four corners of the lower surface of the upper mold plate 410, and a buffer groove 301 is opened at each of the four corners of the upper surface of the lower mold plate 310. The diameter of the buffer groove 301 is the same as the diameter of the buffer column 420;
[0030] A buffer spring is installed at the bottom of the buffer groove 301, the central axis of the buffer groove 301 is aligned with the central axis of the buffer column 420, and a second limit block 430 is installed at each of the four corners of the lower surface of the upper template 410, and the four second limit blocks 430 and the four first limit blocks 330 are symmetrically arranged.
[0031] When in use, when the lower template 310 contacts the upper template 410, the buffer column 420 on the lower surface of the lower template 310 will enter the buffer groove 301 on the upper surface of the lower template 310, and then the lower end of the buffer column 420 will abut against the buffer spring inside the buffer groove 301, thereby absorbing vibrations through the combination of shock-absorbing components, reducing vibration and noise of the mold, protecting the mold from damage, extending the service life of the entire device, and reducing maintenance costs.
