Description

Technical Field

[0001] This utility model relates to the technical field of cooling fan equipment, specifically a mold for producing a dry-type transformer cooling fan. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain the desired products through injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. With the development of the wind power market, higher dimensional accuracy and quality requirements have been put forward for the production of wind turbine blades. The quality of wind turbine blades largely depends on the molds used to produce the blades, which puts forward higher quality requirements for the molds used to produce the blades. That is, the surface aerodynamic dimensions must be accurate, the surface smoothness must be high, there must be no hidden bubbles or pinholes and other defects, and good airtightness must be guaranteed.

[0003] Application number CN202022761785.8 discloses a mold for producing a dry-type transformer cooling fan, comprising a main body, a fixed plate, and support columns. Air inlets are installed on both sides of the main body. A protective layer is installed at the top of the interior of the main body, and a hydraulic telescopic rod is installed at the bottom of the protective layer. An upper template is installed at the bottom of the hydraulic telescopic rod. Ultraviolet lamps are evenly installed at both ends of the bottom of the protective layer, and lamp covers are installed outside the ultraviolet lamps. Cooling structures are provided on both sides of the interior of the main body. A fixed plate is installed inside the main body, and a lower template is installed at the top of the fixed plate. This utility model saves resources by installing a first fan inside the feed hole. When the first fan is activated, excess material seeping from the edges of the upper and lower templates passes through a pre-reserved hole, then through a first water pipe and a discharge hole into the bottom of the interior of the main body for reuse.

[0004] The aforementioned document discloses a mold for producing a dry-type transformer cooling fan, which has the following defects: the fan production requires the manufacture of an outer shell, which is generally a polygonal shell. When the mold workpiece is made, the workpiece needs to be bent. After the workpiece is deformed by the mold components, it is easy to be squeezed into the mold and difficult to demold, which reduces the production efficiency of the mold.

[0005] Therefore, it can be seen that the existing molds do not have the function of quickly demolding the workpiece, and it is necessary to improve them to provide a function that can quickly demold the workpiece. Utility Model Content

[0006] The purpose of this utility model is to provide a mold for producing a dry-type transformer cooling fan, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a mold for producing a dry-type transformer cooling fan, comprising an operating table and a stamping assembly. The stamping assembly is slidably connected to the top outer wall of the operating table. The operating table includes an insert block, and a groove is formed on one side of the outer wall of the insert block. Two sliders are slidably connected to the inner wall of the groove. Movable blocks are welded to one side of the outer wall of each of the two sliders. Grooves are formed on the lower surface of the two movable blocks. A compression spring and a limiting block are provided on the inner wall of the groove. The two limiting blocks are located on opposite sides, and bolts are threadedly connected to the bottom inner wall of the two limiting blocks. The purpose of this design is that, during the use of the mold, the workpiece is placed on the mounting plate, and the telescopic rod drives the stamping block downwards to stamp and bend the workpiece. The stamping block is positioned around its perimeter by the positioning frame, and the limiting plate fixes the fixing plate to the top of the plate. The stamping block drives the protrusion downwards to press against the workpiece, and the protrusion also presses the top block at the bottom of the workpiece downwards. The bottom of the top block presses the two movable blocks on both sides downwards to move outwards. The two movable blocks are limited to move within the slide groove of the insert block by the slider. The bottom is limited to the connecting plate by the bolt and the limiting block. When the two movable blocks move outwards, one end of the compression spring presses against the limiting block to retract. After the stamping assembly returns to its original position, the protrusion releases the pressure on the top block, and the two compression springs rebound, driving the two movable blocks to move inwards. The two movable blocks press against the bottom of the top block, causing the top of the top block to bounce upwards against the workpiece, allowing the workpiece to be quickly demolded. The mounting plate and the insert block are fixed by the insert rod and the positioning rod, which facilitates the disassembly and replacement of internal components on the mounting plate and improves the flexibility of the mold.

[0009] Furthermore, the lower surface of the insert block is provided with a connecting plate, and the bolt is threadedly connected to the inner wall of the connecting plate. The upper surface of the insert block is provided with a mounting plate. The purpose of this arrangement is that, during the use of the mold, the bottom is limited to the connecting plate by the cooperation of the bolt and the limiting block. When the two movable blocks move outward, one end of the compression spring is squeezed and contracted against the limiting block.

[0010] Furthermore, the lower surface of the mounting plate is provided with two insert rods and a positioning rod, which are inserted into the inner wall of the insert block. A top block is slidably connected to the inner wall of the mounting plate, and the bottom end of the top block is located at the inclined surface between the two movable blocks. The purpose of this arrangement is to fix the mounting plate and the insert block by the insert rods and positioning rods during the use of the mold, which facilitates the disassembly and replacement of the internal components of the mounting plate and improves the flexibility of the mold.

[0011] Furthermore, a plate is welded to the lower surface of the connecting plate, and a fixing seat is welded to the lower surface of the plate. A telescopic rod and a stabilizing block are provided on the outer walls of the top perimeter of the plate. The telescopic rod is welded to the upper surface of the plate, and the stabilizing block is located on the outer walls of the telescopic rod. Bolts are threaded onto the inner walls of the stabilizing blocks, extending downwards to the inner walls of the plate. The purpose of this arrangement is that during the use of the mold, the workpiece is placed on the mounting plate, the telescopic rod drives the stamping block downwards to stamp and bend the workpiece, the stamping block is positioned around its perimeter by the positioning frame, and the limiting plate fixes the fixing plate to the top of the plate.

[0012] Furthermore, a fixing plate is sleeved on the outer wall of the telescopic rod, and a fixing plate is installed on the upper surface of the limiting plate. The fixing plate is snapped onto the top outer wall of the telescopic rod, and a stamping block and a positioning frame are provided on the lower surface of the fixing plate. The purpose of this arrangement is that, during the use of the mold, the positioning frame positions the stamping block around its perimeter, the limiting plate fixes the fixing plate to the top of the plate, and the stamping block drives the protrusion to press downwards against the workpiece.

[0013] Furthermore, four bolts are threaded onto the inner wall of the limiting plate, extending downwards to the inner wall of the stamping block. The stamping block is located inside the positioning frame, and a protrusion is provided on the lower surface of the stamping block. The protrusion and the top block are coaxial. The purpose of this arrangement is that during the use of the mold, the protrusion presses the top block at the bottom of the workpiece downwards, and the bottom of the top block presses the two movable blocks on both sides outwards. The two movable blocks are limited by the slider and move within the groove of the insert block.

[0014] This utility model has the following beneficial effects:

[0015] (1) By setting up the compression spring and the slider, the protrusion presses the top block at the bottom of the workpiece downwards. The bottom of the top block presses the movable blocks on both sides to move outwards. The two movable blocks are limited to move in the groove of the insert block by the slider. The bottom is limited to the connecting plate by the bolt and the limiting block. When the two movable blocks move outwards, one end of the compression spring presses and contracts against the limiting block. After the stamping assembly is reset upwards, the protrusion releases the pressure on the top block. The two compression springs rebound and drive the two movable blocks to move inwards. The two movable blocks press the bottom of the top block, so that the top of the top block bounces up against the workpiece, so that the workpiece is quickly demolded.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The positioning frame 203 positions the stamping block 204 around its perimeter, and the limiting plate 201 fixes the fixing plate 202 to the top of the plate 102. The stamping block 204 drives the protrusion 205 downward to press the workpiece, and the protrusion 205 also presses the top block 111 at the bottom of the workpiece downward. The bottom of the top block 111 presses the movable blocks 112 on both sides downward to move outward.

After the stamping assembly 2 is reset upward, the protrusion 205 releases the pressure on the top block 111. The two compression springs 114 rebound and drive the two movable blocks 112 to move inward. The two movable blocks 112 squeeze the bottom of the top block 111, causing the top of the top block 111 to bounce upward against the workpiece, so that the workpiece can be quickly demolded.

The stamping block 204 drives the protrusion 205 downward to press the workpiece. The protrusion 205 also presses the top block 111 at the bottom of the workpiece downward. The bottom of the top block 111 presses the movable blocks 112 on both sides downward to move outward. The two movable blocks 112 are limited in the sliding groove 107 of the insert block 106 by the slider 116. The movement is controlled by the bolt 200 and the limiting... The positioning block 115 cooperates to limit the bottom to the connecting plate 105. When the two movable blocks 112 move outward, one end of the compression spring 114 is squeezed and contracted against the limiting block 115. After the stamping assembly 2 is reset upward, the protrusion 205 releases the pressure on the top block 111. The two compression springs 114 rebound and drive the two movable blocks 112 to move inward.
