Description

Technical Field

[0001] The invention relates to the technical field of ceramic splitting knife processing equipment, in particular to a precision ceramic blank forming device and method for a ceramic splitting knife. Background Art

[0002] Ceramic splitter is a precision tool used in the field of electronic packaging. It is mainly made of ceramic material and usually has the characteristics of high hardness, high wear resistance and good chemical stability. Its shape is generally slender needle-like with a very sharp tip; in the prior art, ceramic splitter blanks can be formed by pressing and injection molding. The pressing method has the advantage of simple process, but the precision of the produced ceramic blanks is poor, and the accuracy of the micropores in the center of the ceramic splitter blank is low. The injection molding method can effectively improve the processing progress of the ceramic blank and ensure the accuracy of the micropores in the center of the ceramic splitter blank. Therefore, injection molding has gradually replaced pressing molding in the molding process of ceramic splitter blanks.

[0003] However, due to the low thermal expansion coefficient of ceramic materials, if the cooling speed is too fast during the cooling process after injection molding, the temperature difference between the inside and the surface of the blank may cause the blank to crack. At the same time, since ceramic splitter blanks are generally slender, they are more prone to uneven cooling. Therefore, when mechanically injecting ceramic splitter blanks, there are restrictions on the structure of the water cooling channel in the mold and the temperature of the cooling water, so that the ceramic splitter blank cannot be quickly demolded after injection molding is completed, and generally needs to wait for about 10-30 minutes.

[0004] Chinese patent CN113696305B discloses a syringe-drawing special ceramic slurry injection molding machine, which can complete the injection molding of multiple products in a single operation; however, multiple syringes are provided in the device, each syringe corresponds to a mold group, and the structure is similar to a combination of multiple injection molding machines, and the injection interval of a single molding machine cannot be reduced.

[0029] (III) Beneficial effects

[0030] Compared with the prior art, the present invention provides a precision ceramic blank forming device and method for a ceramic splitting knife, which has the following beneficial effects:

[0031] 1. The precision ceramic blank forming equipment, by providing a mold installation mechanism, can move the mold to a position away from the injection device after injecting material into the mold, so that the injection device can be used to inject into the inside of another mold, thereby shortening the injection interval of the ceramic splitting knife blank. By providing a movable mold clamping mechanism and a direct pressure mold locking mechanism, during the first half of the cooling time of the ceramic splitting knife blank in the mold, the direct pressure mold locking mechanism is used to clamp the mold to ensure a sufficiently large mold clamping pressure so that the ceramic splitting knife blank can be smoothly formed. During the second half of the cooling time of the ceramic splitting knife blank in the mold, the movable mold clamping mechanism is used instead of the direct pressure mold locking mechanism to clamp the mold. Since the movable mold clamping mechanism is also movable, the movable mold and the fixed mold will not be separated when the mold is moved, thereby preventing the ceramic splitting knife blank that has not completed cooling from contacting the outside world in advance, and preventing the ceramic splitting knife blank from cracking due to the temperature difference between the inside and the outside.

[0032] 2. The precision ceramic blank forming equipment is provided with a matching component, an active hanging component and a baffle, so that when the U-shaped plate is close to the slotted plate, the push-pull plate squeezes the bent plate into the inner side of the U-shaped plate, and then the bent plate is squeezed and contacted with the slotted plate, so that the movable mold clamping mechanism can apply pressure to the movable mold mounting plate to ensure that the movable mold and the fixed mold will not be separated when the mold mounting mechanism is moved. At the same time, when the U-shaped plate is far away from the slotted plate, one side of the push-pull plate abuts against one end of the bent plate located inside the U-shaped plate, and under the support of the elastic support member, the movable mold clamping mechanism can pull the movable mold to separate the movable mold from the fixed mold; when the U-shaped plate continues to move so that the bent plate contacts the baffle, the bent plate rotates so that the distance between one end of the two bent plates located inside the U-shaped plate increases, and the push-pull plate can pass between the two bent plates, so that the movable mold is separated from the movable mold clamping mechanism, which is convenient for controlling the movable mold clamping mechanism to clamp different molds.

[0033] 3. The precision ceramic blank forming equipment is provided with an electric slide, so that the injection equipment can inject molds installed on different mold installation mechanisms. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] Embodiment 1

[0053] See also Figure 1 , Figure 2 and Figure 3 The present invention provides a precision ceramic blank forming device for a ceramic splitter, comprising a base 1, an injection device 2, a mold installation mechanism 3, a movable mold clamping mechanism 4 and a direct pressure type mold locking mechanism 5 are sequentially arranged on the upper surface of the base 1;

[0054] An electric slide 21 is installed at the bottom of the injection device 2, and the electric slide 21 is used to control the injection device 2 to slide back and forth on the upper surface of the base 1;

[0055] The mold installation mechanism 3 includes a mold installation base plate 31, a fixed mold installation plate 33, a movable mold installation plate 35 and a hanging matching component 36. The mold installation base plate 31 is slidably arranged on the upper surface of the base 1, the fixed mold installation plate 33 is fixedly installed on the upper surface of the mold installation base plate 31, and the movable mold installation plate 35 is slidably arranged on one side of the fixed mold installation plate 33. The fixed mold installation plate 33 and the movable mold installation plate 35 are respectively installed with a fixed mold 6 and a movable mold 7 on the opposite side walls. The hanging matching component 36 is fixedly installed on the movable mold installation plate 35.

[0056] The movable mold clamping mechanism 4 includes a die mounting base plate 41 and an active hanging component 44. The die mounting base plate 41 is slidably arranged on the upper surface of the base 1. The active hanging component 44 is movably mounted above the die mounting base plate 41. The active hanging component 44 is hung in cooperation with the hanging matching component 36 to close the fixed mold 6 and the movable mold 7 and to separate the fixed mold 6 and the movable mold 7.

[0057] The mold installation mechanism 3 also includes a stopper 38, which is used to separate the active hanging component 44 from the hanging matching component 36;

[0058] The direct pressure type mold clamping mechanism 5 is fixedly mounted on the base 1 , and the direct pressure type mold clamping mechanism 5 is used to close the fixed mold 6 and the movable mold 7 .

[0059] As can be seen from the above, by setting up the mold installation mechanism 3, after the material is injected into the mold, the mold can be moved to a position away from the injection device 2, so that the injection device 2 can be used to inject into the inside of another mold, thereby shortening the injection interval of the ceramic splitting knife blank. By setting up the movable clamping mechanism 4 and the direct pressure clamping mechanism 5, during the first half of the cooling time of the ceramic splitting knife blank in the mold (the first half of the time refers to the first 40% to 60% of the time period from the completion of injection to the completion of cooling), the direct pressure clamping mechanism 5 is used to clamp the mold to ensure a sufficiently large clamping pressure (because in the early stage of cooling, the plastic melt in the ceramic blank begins to cool down and shrink. If the clamping pressure is not maintained at this time, the melt may be reduced due to the internal pressure The backflow causes the ceramic blank to have defects such as shrinkage marks and cavities), so that the ceramic splitting knife blank can be smoothly formed. In the second half of the cooling of the ceramic splitting knife blank in the mold, the active clamping mechanism 4 is used to replace the direct pressure clamping mechanism 5 to clamp the mold. As the cooling continues, (the clamping pressure should be gradually reduced in the second half of the cooling, and finally the clamping pressure should be reduced to a lower value before demolding). Therefore, at this stage, a device with a lower clamping pressure can be used to replace a device with a higher clamping pressure. Since the active clamping mechanism 4 can also be moved, the active mold 7 and the fixed mold 6 will not be separated when the mold is moved, so that the ceramic splitting knife blank that has not been completely cooled is prevented from contacting the outside world in advance, and the ceramic splitting knife blank is prevented from cracking due to the temperature difference between the inside and the outside;

[0060] By setting the hanging matching component 36, the active hanging component 44 and the stopper 38, when the movable mold clamping mechanism 4 is close to the movable mold mounting plate 35, the hanging matching component 36 and the active hanging component 44 are connected, so that the movable mold clamping mechanism 4 can apply pressure to the movable mold mounting plate 35, ensuring that the movable mold 7 and the fixed mold 6 will not be separated when the mold mounting mechanism 3 is moved and a certain pressure can be maintained. At the same time, when the movable mold clamping mechanism 4 is away from the movable mold mounting plate 35, the movable mold clamping mechanism 4 can pull the movable mold 7 to separate the movable mold 7 from the fixed mold 6. When the movable mold clamping mechanism 4 continues to move, the movable mold clamping mechanism 4 can be separated from the movable mold mounting plate 35 by controlling the stopper 38 without manual intervention.

[0061] In this embodiment, the movable clamping mechanism 4 and the direct pressure locking mechanism 5 are respectively a pressure device that can apply a smaller pressure but can be moved, and a pressure device that cannot be moved but can apply a larger pressure. By arranging the direct pressure locking mechanism 5 to be unable to move, the pressure of the direct pressure locking mechanism 5 is ensured to be stable when the extrusion mold is clamped, thereby avoiding the formation of cracks inside the ceramic splitting knife blank during cooling due to pressure changes. The pressure applied by the movable clamping mechanism 4 to the ceramic splitting knife blank is relatively small. At the same time, when the movable clamping mechanism 4 applies pressure to the ceramic splitting knife blank, the ceramic splitting knife blank has gone through more than half of the cooling time, and the internal structure has gradually stabilized. Even if a certain pressure change occurs, it is not easy to affect the internal structure of the ceramic splitting knife blank.

[0062] When the device is used, the movable mold 7 is pushed to close the mold with the fixed mold 6 through the direct pressure clamping mechanism 5, and the material for ceramic splitter molding is added into the drying barrel of the injection device 2, and the injection device 2 is driven to move through the electric slide 21, so that the nozzle of the injection device 2 is docked with the gate of the fixed mold 6, and the material heated and molten by the injection device 2 is injected into the mold; after the cooling time of the ceramic splitter blank inside the mold exceeds half, the movable mold closing mechanism 4 is used to replace the direct pressure clamping mechanism 5 to support the movable mold 7, so that the movable mold 7 and the fixed mold 6 are kept in the closed mold state, and the direct pressure clamping mechanism 5 is retracted; the mold installation mechanism 3 and the movable mold closing mechanism 4 are controlled to move, so that the ceramic splitter blank inside is cooled down, and the ceramic splitter blank ... The mold of the ceramic splitting knife blank is moved to one side, and another mold installation mechanism 3 with an idle mold installed inside is moved to the side of the injection device 2; the idle mold is closed by the direct pressure clamping mechanism 5, and the injection device 2 is used to inject into the idle mold; before the cooling time of the ceramic splitting knife blank inside the mold that has recently completed injection reaches half, the cooling of the ceramic splitting knife blank inside the mold that has previously completed injection is completed, and the movable mold 7 is separated from the fixed mold 6 by the movable clamping mechanism 4, the ceramic splitting knife blank inside is taken out, and after the cooling time of the ceramic splitting knife blank inside the mold that has recently completed injection reaches half, the movable mold 7 is supported by the movable clamping mechanism 4 instead of the direct pressure clamping mechanism 5.

[0063] Embodiment 2

[0064] like Figure 4 and Figure 5 As shown, the difference between this embodiment and the above embodiment is that the mold mounting mechanism 3 also includes an opening frame 32 and a guide rod 34, the opening frame 32 is fixedly mounted on the upper surface of the mold mounting base plate 31, and a square hole 37 is opened on the opening frame 32, the two ends of the guide rod 34 are respectively fixedly connected to the opening frame 32 and the fixed mold mounting plate 33, and the movable mold mounting plate 35 is slidably sleeved on the guide rod 34.

[0065] As can be seen from the above, by providing the opening frame 32 and the guide rod 34 , the sliding direction and sliding distance of the movable mold mounting plate 35 can be controlled.

[0066] The active hanging component 44 includes a U-shaped plate 441, a bending plate 442 and a spring 443, and the hanging matching assembly 36 includes a slotted plate 361, an elastic support member 362 and a push-pull plate 363. The bending plate 442 is rotatably installed at the end of the U-shaped plate 441, and the two ends of the spring 443 are rotatably connected to one side outer wall of the U-shaped plate 441 and one end of the bending plate 442 respectively. The slotted plate 361 is fixedly installed on a side wall of the movable mold mounting plate 35, and the two ends of the elastic support member 362 are fixedly connected to the slotted plate 361 and the push-pull plate 363 respectively. The push-pull plate 363 is sleeved inside the U-shaped plate 441, and the angle between the two ends of the bending plate 442 is greater than ninety degrees. The distance between the two bending plates 442 is greater than the distance between the blocking rods 38, and the distance between the two bending plates 442 close to each other at one end is less than the length of the push-pull plate 363.

[0067] As can be seen from the above, when the U-shaped plate 441 is close to the slotted plate 361, the push-pull plate 363 squeezes the bending plate 442 and enters the inner side of the U-shaped plate 441, and then the bending plate 442 is squeezed and contacted with the slotted plate 361, so that the movable clamping mechanism 4 can apply pressure to the movable mold mounting plate 35 to ensure that the movable mold 7 and the fixed mold 6 will not be separated when the mold mounting mechanism 3 is moved. At the same time, when the U-shaped plate 441 is far away from the slotted plate 361, one side of the push-pull plate 363 abuts against one end of the bending plate 442 located inside the U-shaped plate 441, and under the support of the elastic support member 362, the movable clamping mechanism 4 can pull the movable mold 7 to separate the movable mold 7 from the fixed mold 6.

[0068] The blocking rods 38 are symmetrically fixed on both sides of the square hole 37 , the U-shaped plate 441 passes between the two blocking rods 38 , and the distance between the two bent plates 442 at one end away from each other is greater than the distance between the two blocking rods 38 .

[0069] As can be seen from the above, when the U-shaped plate 441 continues to move so that the bending plate 442 contacts the blocking rod 38, the bending plate 442 rotates so that the distance between one end of the two bending plates 442 located inside the U-shaped plate 441 increases, and the push-pull plate 363 can pass between the two bending plates 442, so that the movable mold 7 is separated from the movable clamping mechanism 4, which facilitates the control of the movable clamping mechanism 4 to clamp different molds.

[0070] Embodiment 3

[0071] like Figure 2 , Figure 3 , Figure 6 and Figure 7 It is shown that the difference between this embodiment and the above-mentioned embodiment is that the movable clamping mechanism 4 also includes a lifting drive device 42 and a translation propulsion device 43, the lifting drive device 42 is fixedly mounted on the die mounting base plate 41, the translation propulsion device 43 is fixedly mounted on the driving end of the lifting drive device 42, and the U-shaped plate 441 is fixedly mounted on the driving end of the translation propulsion device 43.

[0072] The direct pressure clamping mechanism 5 includes a support seat 51, a hydraulic cylinder 52 and a U-shaped pressure plate 53. The support seat 51 is fixedly mounted on the upper surface of the base 1, the hydraulic cylinder 52 is fixedly mounted on the support seat 51, the U-shaped pressure plate 53 is fixedly mounted on the driving end of the hydraulic cylinder 52, and both ends of the U-shaped pressure plate 53 pass through the square hole 37 and abut against a side wall of the movable mold mounting plate 35, and the two ends of the U-shaped pressure plate 53 are symmetrically arranged on both sides of the slotted plate 361 and the blocking rod 38.

[0073] As can be seen from the above, by setting up the lifting drive device 42, the translation propulsion device 43 and the U-shaped pressure plate 53, the active hanging component 44 can change the height and push the movable mold 7 to move. When the movable mold clamping mechanism 4 is used instead of the direct pressure clamping mechanism 5, it is necessary to lower the height of the translation propulsion device 43 and the active hanging component 44 through the lifting drive device 42, so that the translation propulsion device 43 and the active hanging component 44 can pass from under the U-shaped pressure plate 53, and the translation propulsion device 43 and the active hanging component 44 can be raised from the middle of the U-shaped pressure plate 53 to a suitable height to apply pressure to the movable mold mounting plate 35.

[0074] Embodiment 4

[0075] like Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, the difference between this embodiment and the above embodiment is that a driving mechanism 8 is installed on the upper surface of the base 1, and the driving mechanism 8 includes a slide 81, a mold sliding guide rod 82, a mold sliding screw rod 83, a die sliding guide rod 84, a die sliding screw rod 85, a mold sliding drive motor 86 and a die sliding drive motor 87, both ends of the mold sliding guide rod 82 and the die sliding guide rod 84 are fixedly connected to the inner walls on both sides of the slide 81, and both ends of the mold sliding screw rod 83 and the die sliding screw rod 85 are rotatably connected to the two ends of the slide 81. The mold mounting base plate 31 is slidingly connected to the mold sliding guide rod 82, and the mold mounting base plate 31 is threadedly connected to the mold sliding screw 83, the die mounting base plate 41 is slidingly connected to the die sliding guide rod 84, and the die mounting base plate 41 is threadedly connected to the die sliding screw 85, the mold sliding drive motor 86 and the die sliding drive motor 87 are both fixedly mounted on one side outer wall of the slide 81, and the driving ends of the mold sliding drive motor 86 and the die sliding drive motor 87 are fixedly connected to the mold sliding screw 83 and the die sliding screw 85 respectively.

[0076] As can be seen from the above, the sliding of the mold mounting base plate 31 and the die mounting base plate 41 on the base 1 is controlled by the mold sliding drive motor 86 and the die sliding drive motor 87 respectively.

[0077] Embodiment 5

[0078] like Figure 2 and Figure 7 As shown, the difference between this embodiment and the above embodiment is that a discharge port 88 penetrating the upper and lower surfaces of the slide seat 81 is provided, and a blanking port 39 connecting the upper and lower surfaces of the mold mounting base plate 31 is provided.

[0079] A flexible chain conveyor 9 is disposed inside the base 1 , and the lower side of the discharge port 88 is opposite to the upper surface of the flexible chain conveyor 9 .

[0080] By providing the discharge port 88, the drop port 39 and the flexible chain conveyor 9, the demoulded ceramic splitting knife blank can directly fall onto the flexible chain conveyor 9 when the mold is opened, so as to facilitate the collection of the formed ceramic splitting knife blank.
