[0002] Wax molds are a key component in investment casting, mainly used to make stainless steel and other metal castings. During the manufacturing process, the mold is usually made of aluminum, and then wax is injected into the mold to form a wax pattern, which is called a wax mold. The quality of the wax mold directly affects the dimensional accuracy and surface finish of the casting. Therefore, the production of wax molds requires a high level of technology and precise control.

[0003] However, when injecting wax liquid into the mold, the upper mold and the lower mold of the mold need to be installed together through a fixing assembly first. When the upper mold and the lower mold are misaligned during the fixing process, it is easy to affect the size and shape of the wax mold after solidification, and the wax mold is deformed, which is not convenient for subsequent casting of metal castings. When removing the mold from the wax mold, the operator needs to use tools to pry the mold, which is inconvenient to operate.

[0011] The beneficial effects of the present invention are:

[0012] (1) The wax mold mold that is easy to demold described in the present invention has a locking mechanism installed in the lower mold, and then the upper mold is placed on the lower mold. The upper mold and the lower mold can be fixed and limited by the installation mechanism. The wax mold mold can be installed on a disc-type wax injection machine by the fixing mechanism, and wax can be injected into the mold. That is, the operator locks the first clamping block into the clamping groove provided in the second clamping block, so that the first clamping block and the second clamping block can be assembled together, and then clamped into the lower mold, so that the first clamping block can contact the inner wall of the lower mold, and then two clamping rods are clamped into the position between the first clamping block and the second clamping block, so that the clamping rods can seal the ends of the first clamping block and the second clamping block, and then the upper mold is clamped to the top of the lower mold, and the side walls of the upper mold are symmetrical. Two groups of fixed blocks are installed, and two groups of mounting blocks are symmetrically installed on the side walls of the lower mold. When the fixed block contacts the mounting block, the connecting block arranged in the mounting block can be rotated. A positioning rod is fixed on the top of the connecting block. The positioning rod is rotated to make it engage with the positioning groove provided in the fixed block. A tool is used to rotate the rotating block provided on the positioning rod. When the rotating block is rotated to a state of conflicting with the top of the fixed block, the rotating block can limit the positioning rod, and then the upper mold can be fixed on the lower mold, which is beneficial to improve the sealing effect of the mold; the plug-in block fixed on the side wall of the lower mold is placed on the side wall of the limiting rod. Now the limiting block can limit the plug-in block, which is convenient for fixing the lower mold on the base plate. The base plate can be fixed on the disc-type wax injection machine through the positioning bolts.

[0013] (2) The wax mold mold that is easy to demold described in the present invention is that after the wax mold solidifies, the installation mechanism is rotated to put the upper mold in an unrestricted state, and then the sliding mechanism is pressed to make it slide in the upper mold, thereby separating the sliding mechanism from the solidified wax mold. When taking out the upper mold, it can be separated from the wax mold, that is: after the wax injection machine injects wax liquid into the mold, after the wax mold solidifies, the rotating block can be rotated to rotate the positioning rod out of the fixed block, thereby making the fixed block lose the limit of the rotating block, which is convenient for the subsequent removal of the upper mold from the lower mold; by pressing the handle fixed at the end of the plate with your hand, the upper mold can be removed from the lower mold. The handle drives the connecting shaft fixed on the support plate to rotate, and the connecting shaft rotates in the upper mold, and a torsion spring is sleeved on one end of the connecting shaft, and both ends of the torsion spring are fixedly connected to the upper mold and the connecting shaft. When the support plate rotates, the torsion spring is deformed, so that the end of the support plate contacts the bottom end of the fixed plate. A clamping plate is installed on the fixed plate. When the fixed plate slides in the upper mold, the clamping plate can drive the slider fixed at the bottom to slide into the upper mold. The slider was originally in contact with the solidified wax mold. When it slides into the inside of the upper mold, it can be separated from the wax mold, thereby reducing its contact area with the wax mold, which is conducive to the subsequent removal of the upper mold from the lower mold.

[0014] (3) The wax mold mold that is easy to demold described in the present invention is characterized in that the locking mechanism is taken out from the lower mold, and the control switch of the resistance mechanism is turned on to make it slide out of the lower mold and eject the solidified wax mold, thereby facilitating the rapid disassembly of the wax mold, that is, the first clamping block and the second clamping block are taken out from the formed wax mold so that the wax mold can be located in the lower mold, and then the control switch of the hydraulic rod is turned on. The hydraulic rod is fixedly installed in a slide groove portion provided in the lower mold. When the hydraulic rod is started, its telescopic end drives the resistance block fixed thereto to slide, and the resistance block slides out of the slide groove, so that the top end of the resistance block resists the wax mold. When the wax mold is ejected from the lower mold, it can slide in the molding groove portion provided in the lower mold, and the contact area between the wax mold and the lower mold is reduced, which is convenient for the operator to take out the formed wax mold, which is beneficial to improving the use effect of the mold.
