Description

Technical Field

[0001] The utility model belongs to the technical field of mold splitting, and in particular relates to a lifting device for splitting injection mold plates. Background Art

[0002] As a clean energy, wind energy is gaining more and more attention. Wind energy is a clean, pollution-free and renewable energy source that has been used by people for a long time, mainly through windmills to pump water and grind flour. People are interested in how to use wind power to generate electricity. The parts of wind power generation equipment are generally made through molds during production, and after production, it is generally necessary to use a flipping device to flip the mold to take out the parts inside the mold. This casting method is time-consuming and labor-intensive, and has high costs, which does not meet the current market demand.

[0003] To this end, a wind power accessory casting mold with a bulletin number of "CN217912729U" includes a base plate, a first lower template is movably connected to the left side of the top of the base plate, a second lower template is movably connected to the right side of the top of the base plate, both sides of the top of the base plate are fixedly connected to vertical plates, the bottom of the opposite side of the vertical plates is fixedly connected to a first threaded sleeve, and the first lower template and the side opposite to the second template are movably connected to a first screw. The utility model cooperates with the base plate, the first lower template, the second lower template, the vertical plate, the first threaded sleeve, the first screw, the upper template, the slot, the block, the cross plate, the positioning plate, the limit plate, the plug rod, the groove, the second screw, the second threaded sleeve, the limit rod and the injection port, so that the wind power accessory casting mold can quickly demould the finished casting through a convenient demoulding structure, thereby improving the use efficiency and practicality of the wind power accessory casting mold.

[0004] However, for the above-mentioned wind power accessory casting mold, although the staff released the limit on the upper template and moved the upper template to the appropriate position when pulling the handle, there are still the following obvious defects during use: the upper template is fixed at the bottom of the horizontal plate and is lifted and lowered by the vertical plate. This way of fixing the upper template requires the entire mold to be replaced in the later stage due to wear and tear, and it is impossible to replace each template in the mold separately if it is severely worn after disassembly, which makes the cost of using the injection mold higher. Utility Model Content

[0005] The purpose of the utility model is to provide a lifting and disassembling device for injection molding template molds to solve the problems raised in the above background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a device for disassembling and lifting injection molds, comprising:

[0007] A template splitting frame, wherein both sides of the bottom end of the template splitting frame are movably provided with splitting movable plates for moving the splitting template, and the ends of the splitting movable plates arranged on both sides of the template splitting frame are respectively provided with a splitting left template and a splitting right template for injection molding of wind power castings;

[0008] The split upper template has quick-release cylinders on both sides for plugging and fixing the split upper template, and a split lifting cylinder for lifting and splitting the split upper template is vertically provided at the end of the cylinder body of the quick-release cylinder through a fixed block, and one end of the cylinder body of the split lifting cylinder is fixed on both sides of the upper end inside the template splitting frame.

[0009] Preferably, slide grooves are laterally provided on both sides of the inner bottom surface of the template splitting frame, a directional slider is provided at the bottom of the splitting movable plate, and the directional slider is slidably arranged in the slide groove to move the splitting movable plate to combine or split the template, so that the left and right templates can be pneumatically combined to cast wind power castings, reducing the steps of manual operation of the staff, and the combined templates can be quickly split to demold the wind power castings.

[0010] Preferably, a template mounting vertical plate is provided at the end of the split movable plate, and the split left template and the split right template are fixed to one side of the template mounting vertical plate by screws. A cylinder is provided on one side of the template mounting vertical plate, and the cylinder is fixed to the two side walls inside the template splitting frame. The left and right templates can be installed on one side of the template mounting vertical plate by means of screws, and it is beneficial to replace any one template separately after the template is severely worn in the later stage, thereby reducing unnecessary usage costs.

[0011] Preferably, the end sides of the split left template and the split right template are provided with positioning concave grooves downwardly, and the bottom side of the split upper template is provided with a template combination positioning frame. After the left and right templates are molded together, the stability of the two templates after the mold is closed can be enhanced by combining the template combination positioning frame and the positioning concave grooves.

[0012] Preferably, both sides of the split upper template are provided with disassembly slots, one end of the piston rod of the quick-release cylinder is fixed with a fixed plate, and one side of the fixed plate is provided with a disassembly rod that is compatible with the disassembly slot, so that the split upper template can be quickly disassembled and replaced.

[0013] Preferably, one end of the piston rod of the split lifting cylinder is fixed to one side of the end of the fixed block, and the quick-release cylinder is fixed to the side of one end of the fixed block, so that the split upper template can be pneumatically put on to achieve installation and disassembly of the template and replacement and installation.

[0014] Compared with the prior art, the technical effects and advantages of the utility model are as follows: the mold splitting and lifting device for injection molding template type mold, through the combination of the splitting and lifting cylinder, the cylinder, the fixed block, the disassembly and assembly rod and the split upper template, can make the split upper template use the splitting and lifting cylinder to pneumatically split with the split left template and the split right template. At the same time, in the case of severe wear and insufficient mold closing accuracy, the splitting and lifting cylinder is moved downward to make the split upper template fit on the split left template and the split right template. The disassembly and assembly rod is separated from the disassembly and assembly rod by the retraction of the cylinder, so that the split upper template can be separated from the disassembly and assembly rod on the cylinder, so that the split upper template can be removed and replaced with a new split upper template for use. This method of splitting the upper template can realize the separate splitting and replacement of the template in the injection mold, thereby eliminating the need to replace the injection mold as a whole, further reducing the use cost of the injection mold, and then realizing the pneumatic lifting and splitting of the injection mold in a simple splitting method, reducing unnecessary manual operation replacement steps.

[0015] Through the cooperation of the directional slider, the template mounting vertical plate and the cylinder on the split moving plate, the split left template and the split right template can be moved to the middle of the template splitting frame at the same time for mold closing, so that the split upper template can be accurately molded with the left and right split templates to perform injection molding of wind power castings, thereby avoiding the situation where the template deviates from the middle position of the mold closing during the movement process of the screw, causing the upper template to produce a mold closing offset during the mold closing, further improving the precision and stability of multiple injection templates during the mold closing process, reducing the need to correct the template mold closing position, and improving the efficiency of wind power casting injection molding.
