Description

Quick assembly disassembly structure and method for heavy-duty mold Technical Field The application relates to the field of die manufacturing, in particular to a rapid disassembly and assembly structure and a rapid disassembly and assembly method for a heavy die. Background In modern manufacturing industries such as metal stamping, plastic injection molding, die casting, etc., the heavy-duty die 2 is a key process device for realizing mass and high-precision production. Such molds are typically extremely heavy, so that the mounting, locking and dismounting operations between the mold and the frame are the core links in the process of preparation for production and mold replacement. At present, the installation and fixation of heavy-duty dies generally adopt a traditional bolt fastening mode or use a special clamp. The bolt fastening method requires an operator to use a large spanner to manually screw or disassemble a plurality of high-strength bolts in sequence. When in operation, a plurality of operators are required to cooperatively operate, so that the labor intensity is high, the potential safety hazard is high, and the efficiency is low. The upper die set and the lower die set of the die are required to be clamped respectively by the clamping force by adopting the special clamp, and especially for heavy dies, the required clamp power requirement is high, and the initial investment cost and the later maintenance cost are high. In view of the above-mentioned related art, when the mold needs to be withdrawn for replacement, the initial separation action of the mold and the mold frame is extremely difficult due to the huge static friction force and the dead weight of the mold, and thus the inventors have recognized that it is necessary to provide a quick-release structure and method for a heavy-duty mold. Disclosure of Invention In order to improve the rapid disassembly and assembly effect of a heavy-duty die and a die carrier bracket, the application provides a rapid disassembly and assembly structure and a rapid disassembly and assembly method for a heavy-duty die. In a first aspect, the present application provides a quick assembly disassembly structure for a heavy-duty mold, which adopts the following technical scheme: The quick dismounting structure for the heavy-duty die comprises a mounting die frame and the heavy-duty die arranged on the mounting die frame, wherein the mounting die frame comprises a lower die holder for supporting the heavy-duty die, an upper die frame and wedge block assemblies wedged between the heavy-duty die and the mounting die frame, the heavy-duty die is provided with an upper mounting portion and a lower mounting portion, the upper mounting portion is provided with an upper guide surface which is inclined towards two sides of the heavy-duty die from bottom to top, the lower mounting portion is provided with a lower guide surface which is inclined towards two sides of the heavy-duty die from top to bottom, the upper die frame is provided with an upper mounting groove which is matched and locked with the upper mounting portion, the lower die holder is provided with a lower mounting groove which is matched and locked with the lower mounting portion, and pushing assemblies which are slidably mounted on two sides of the lower mounting groove, the pushing assemblies comprise an ejection unit and a pushing unit which are arranged on one side of the lower mounting portion, and the end parts of the ejection unit and the pushing unit are respectively parallel to the corresponding lower guide surface. Through adopting above-mentioned technical scheme, through setting up the heavy mould that has slope upper guide face and lower guide face to cooperate with mounting groove and the voussoir subassembly that corresponds on the die carrier, utilize the inclined plane direction and the principle that the voussoir locking combined together, realized heavy mould on the die carrier of installation quick, accurate location and firm locking. The pushing components which are installed on two sides of the lower installation groove in a sliding mode are arranged, the heavy-duty die is pushed in through the pushing unit, movement of the heavy-duty die with large weight can be achieved, and the assembly efficiency of the heavy-duty die is remarkably improved. During disassembly, the heavy-duty die is ejected out by the ejection unit, the end part is parallel to the lower guide surface, and the horizontal thrust can be decomposed through the friction of the inclined surface to generate the friction force along the inclined surface, so that huge static friction between the lower guide surface and the groove wall of the lower mounting groove is converted into dynamic friction, the probability and the effect of disengagement are improved, and the labor intensity and the safety risk of operators are reduced. The push-in unit comprises push-in driving pieces and push-in rods driven by the push-in driving p
