Technical Field
[0001] The utility model relates to the technical field of injection molds, in particular to a mold fixing structure. Background Art
[0002] An injection molding machine, also known as a high-speed injection molding machine or high-speed injection machine, is the primary molding equipment used to create various shapes of plastic products from thermoplastics or thermosetting materials using plastic molding molds. High-speed injection molding machines heat the plastic and apply high pressure to the molten plastic, causing it to eject and fill the mold cavity. Production begins with the injection molding machine, which first loads the plastic mold and then removes it after production is complete.
[0003] The traditional injection mold fixing structure currently used in the market still has shortcomings during use. Most of them are fixed in one direction by bolts. When fixing and replacing, it often takes a long time, the replacement speed is slow, and the efficiency is low. The mold cannot be accurately positioned during installation, which is prone to errors and poor stability, resulting in low product accuracy. Therefore, in order to solve such problems, we proposed a mold fixing structure. Utility Model Content

[0010] Further preferably, the lifting drive assembly includes a plurality of hydraulic rods provided on the lower plate of the injection molding machine.
[0011] The utility model achieves the following beneficial effects:

[0022] Zero point locators 90 are respectively provided around the upper fixed template 31 and the lower fixed template 32 of the mold 30 .
[0023] When fixing the mold 30, the operator inserts the four pull pins 80 below the upper plate 10 of the injection molding machine into the four zero-point locators 90 on the fixed template 31 of the mold 30. Then, the four zero-point locators 90 on the fixed template 31 of the mold 30 are actuated to clamp the four pull pins 80 respectively, thereby fixing the upper plate 10 of the injection molding machine and the upper fixed template 31 of the mold 30. At the same time, the magnetic template 50 on the upper plate 10 of the injection molding machine is magnetized to fix the upper fixed template 31 of the mold 30.
[0024] After that, the four pull pins 80 above the lower plate 20 of the injection molding machine are inserted into the four zero point locators 90 on the lower fixed template 32 of the mold 30, and then the four zero point locators 90 on the fixed template 31 of the mold 30 are actuated to clamp the four pull pins 80 respectively.

Based on this solution, the positioning carrier plate 70 of the present application can be fixed at multiple positions and can be disassembled, which is more flexible to use.
[0027] Specifically, the two magnetic templates 50 of the present application are fixed to the upper plate 10 and the lower plate 20 of the injection molding machine by bolts (not marked), so that they can be quickly disassembled and assembled, and have strong practicality.
