Description

Technical Field

[0001] This invention relates to the field of die-casting mold technology, and in particular to a die-casting mold and die-casting method for a laser cutting machine housing. Background Technology

[0002] The laser cutting machine housing prevents the cutting head from colliding with the workpiece or external objects through physical barriers and integrated sensors (such as limit switches and infrared sensors), avoiding damage to high-precision optical components; and the housing can provide rigid support for the equipment, reducing the impact of vibration on cutting accuracy.

[0003] Please refer to the following: Figure 1 The diagram shows the specific structure of the laser cutting machine housing 300, which the inventor has independently developed and is already in use. The laser cutting machine housing 300 is a die-cast frame structure. A top cover needs to be installed on the top of the laser cutting machine housing 300, and a bottom cover needs to be installed at the bottom. For the inner side of the laser cutting machine housing, mounting protrusions 3001 need to be provided to install components such as limit switches and infrared sensors. Due to limitations in the existing die-casting mold structure, a side cavity can only be set at the lower mold core position of the die-casting mold. Metal slurry is injected into the side cavity, and a metal milling position 3003 is formed on the inner side of the laser cutting machine housing. Subsequently, the mounting protrusions 3001 are milled using CNC machining, and holes 3002 for installing limit switches and infrared sensors are drilled into the mounting protrusions 3001.

[0004] However, the inventors discovered in actual production operations that this production process has the following drawbacks: First, the laser cutting machine housing production process includes die casting, milling, and drilling. The forming process is time-consuming and not suitable for large-scale production. Second, when milling and drilling the die-cast laser cutting machine housing, it is necessary to clamp the laser cutting machine housing on the CNC machining center's worktable. However, there are often deviations in the clamping position, which causes the installation protrusions and hole positions and dimensions to fail to meet the design requirements, seriously affecting the production yield of the laser cutting machine housing.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Summary of the Invention

[0006] In view of this, the present invention addresses the deficiencies of the prior art, and its main objective is to provide a die-casting mold for laser cutting machine housings, effectively solving the technical defects of low production efficiency and low production yield in the prior art for laser cutting machine housings.

[0007] This invention provides a die-casting mold for a laser cutting machine housing, comprising:

[0008] The lower mold base has a lower mold core on top;

[0009] The upper mold base is movable up and down and installed on top of the lower mold base. The upper mold core is provided at the bottom of the upper mold base.

[0010] The lower mold core has a lower punch at the top and an upper mold core has an upper punch at the bottom. The lower mold base has a side slide that can be movably installed on the side of the lower punch. When the upper mold base is closed relative to the lower mold base, the lower punch, the upper punch and the side slide can form a forming cavity for die casting to form a laser cutting machine housing.

[0011] The lower punch has a first forming notch on both the front and rear sides. The first forming notch penetrates the upper surface of the lower punch and is connected to the forming cavity. The bottom of the upper die core has a forming insert. When the upper die base moves down relative to the lower die base to complete the mold closing, the forming insert can be inserted into the first forming notch and die-cast to install the protrusion.

[0012] The beneficial effects of the die-casting mold for laser cutting machine housing provided by this invention are as follows: Compared with the prior art, by setting a lower punch, an upper punch, and a side slide, a forming chamber for die-casting the laser cutting machine housing can be constructed; and a first forming notch is set on both the front and rear sides of the upper punch, which, together with the forming insert structure, can complete the die-casting of the mounting protrusion on the inner side of the laser cutting machine housing. This mechanism simplifies the forming process of the laser cutting machine housing, eliminating the need for subsequent CNC milling of the mounting protrusion, thereby shortening production time and improving production efficiency; on the other hand, the mounting protrusion can be die-cast in one step with the laser cutting machine housing, ensuring that the position of the mounting protrusion meets the design requirements, thus improving the production yield of the laser cutting machine housing.

[0013] As a preferred embodiment, the lower surface of the upper mold core is provided with multiple gating channels, one end of which extends toward the molding cavity and is connected to the molding cavity.

[0014] The upper mold base is equipped with a sprue sleeve, which is connected to the other end of multiple injection channels.

[0015] As a preferred embodiment, the lower mold base is provided with a first ejector plate that can move up and down. The upper surface of the first ejector plate is provided with a first ejector pin. The first ejector pin extends upward to the bottom of the first forming notch and is driven by the first ejector plate to extend and retract within the first forming notch.

[0016] The first ejector pin has at least a cylindrical support at its top, and the cylindrical support is detachably fitted with a metal embedded part; the bottom of the molded insert is provided with a circular limiting hole for the cylindrical support to be inserted.

[0017] After the upper mold base moves down and closes with the lower mold base, the cylindrical support part can be inserted into the circular limiting hole, and the bottom of the forming insert presses against the metal embedded part.

[0018] Compared with existing technologies, by installing metal embedded parts in the cylindrical support and using the metal embedded parts and mounting protrusions to form a molded shape, holes can be pre-set in the metal embedded parts. The assembly of these holes with the cylindrical support ensures that the subsequent holes meet the geometric and positional accuracy specified in the design, thereby ensuring the reliability of the subsequent assembly of limit switches and infrared sensors.

[0019] As a preferred embodiment, the first ejector pin includes

[0020] The lower needle body is fixedly mounted at its bottom to the upper surface of the first ejector plate; and,

[0021] The upper needle body has a bottom that can be rotatably mounted on the top of the lower needle body;

[0022] The top of the upper needle body is a cylindrical support part, which is a hollow tubular structure and forms the first cavity; the side of the cylindrical support part is provided with a first window that connects to the first cavity; a limiting ball is installed inside the first cavity; the limiting ball can extend downward from the first window through the action of elastic rubber; the diameter of the limiting ball is larger than the diameter of the first window.

[0023] Metal embedded parts have holes that penetrate their upper and lower surfaces. When the cylindrical support is inserted into the hole, the limiting ball can abut against the surface of the hole.

[0024] Compared with existing technologies, when installing metal embedded parts, the cylindrical support is directly inserted into the hole and the limiting ball provides resistance to the metal embedded part. By inserting the cylindrical support into the hole, the geometric and positional accuracy of the hole can be guaranteed to meet the design requirements. At the same time, after the die-casting and laser cutting machine housing is completed, the limiting ball structure facilitates the demolding of the first ejector pin from the metal embedded part.

[0025] As a preferred option, the lateral movement includes

[0026] The front sliding part is located in front of the lower punch and can be moved back and forth on the lower die holder via the front moving seat;

[0027] The rear sliding part is located behind the lower punch and can be moved back and forth on the lower die holder via the rear movable seat;

[0028] The left-side sliding member, located to the left of the lower punch, is mounted on the lower die holder and can be moved left and right via a left-side movable seat; and,

[0029] The right-side slide is located on the right side of the lower punch and can be moved left and right on the lower die holder via the right-side movable seat;

[0030] The front slide has a first punch on the side of the downward-facing punch, which is used for die-casting the front recess of the laser cutting machine housing; the rear slide has a second punch on the side of the downward-facing punch, which is used for die-casting the rear recess of the laser cutting machine housing; and the right slide has a third die on the side of the downward-facing punch, which is used for die-casting the right protrusion of the laser cutting machine housing.

[0031] As a preferred embodiment, after the front slide, rear slide, left slide and right slide form the forming chamber for die casting laser cutting machine housing, the front end of the left slide and the left end of the front slide form the second forming notch for the mounting wing of the die casting laser cutting machine housing, and the rear end of the left slide and the left end of the rear slide form the second forming notch for the mounting wing of the die casting laser cutting machine housing.

[0032] As a preferred embodiment, the right slide is provided with a first mounting cavity, which extends to the left through the surface of the third die part and to the right through the right surface of the right slide;

[0033] The first mounting cavity is provided with an upper clamping block, a driving block and a lower clamping block from top to bottom. The lower clamping block is fixedly installed on the right side movable seat. The left ends of the upper clamping block, the driving block and the lower clamping block can protrude from the third die part and be used for die casting to form the right side window of the laser cutting machine housing.

[0034] When the right moving seat moves to the right, the drive block can move the upper and lower clamping blocks away from each other; when the right moving seat moves to the left, the drive block can move the upper and lower clamping blocks closer to each other.

[0035] As a preferred embodiment, the front movable seat is provided with a front guide hole that runs through its upper and lower surfaces and slopes from bottom to top and back, and the bottom of the upper mold base is provided with a front inclined rod that can be inserted into the front guide hole;

[0036] The rear movable seat is provided with a rear guide hole that runs through its upper and lower surfaces and tilts from bottom to top and forward. The bottom of the upper mold base is provided with a rear inclined rod that can be inserted into the rear guide hole.

[0037] The left movable seat is provided with a left guide hole that runs through its upper and lower surfaces and tilts from bottom to top and to the right. The bottom of the upper mold base is provided with a left inclined rod that can be inserted into the left guide hole.

[0038] The right movable seat is provided with a right guide hole that runs through the upper and lower surfaces and tilts from bottom to top and to the left. The bottom of the upper mold base is provided with a right inclined rod that can be inserted into the right guide hole.

[0039] The path of the upper mold base moving relative to the lower mold base is defined as the first axis, the extension direction of the left inclined rod is defined as the second axis, and the extension direction of the right inclined rod is defined as the third axis. The first axis and the second axis form a first angle, and the first axis and the third axis form a second angle. The second angle is greater than the first angle.

[0040] As a preferred embodiment, the lower punch has an inclined insert on the left side, which can move obliquely upward to the right. The left side of the inclined insert has a fourth punch part for the inner recess of the left inner surface of the laser cutting machine housing for die casting.

[0041] The lower mold base is provided with a first drive plate that can move up and down. The first ejector plate and the first drive plate are stacked on top of each other. The bottom of the inclined insert is pivotally connected to the first drive plate.

[0042] The path of the oblique inlay moving obliquely upward is defined as the fourth axis. The fourth axis and the first axis form a third angle, which is smaller than the first angle.

[0043] This invention also provides a die-casting method for a laser cutting machine housing, using a die-casting mold for the laser cutting machine housing, the die-casting method comprising:

[0044] Step 1: Provide a die-casting mold for the laser cutting machine housing and install the die-casting mold for the laser cutting machine housing onto the die-casting machine;

[0045] Step 2: The die-casting machine drives the upper mold base to move, causing the upper mold base to open with the lower mold base;

[0046] Step 3: Provide the metal embedded parts and install the metal embedded parts onto the cylindrical support part;

[0047] Step 4: The die-casting machine drives the upper mold base to move and close with the lower mold base, forming a cavity composed of the upper punch, lower punch, forming insert and side slide.

[0048] Step 5: Provide molten metal and inject it from the sprue sleeve through the injection system of the die casting machine, and then inject it into the molding chamber through the gating channel; after the molten metal cools and solidifies, it is die-cast into the laser cutting machine housing and the mounting protrusion, and the metal of the mounting protrusion can cover the metal embedded part;

[0049] Step 6: The die-casting machine drives the upper mold base to move, so that the upper mold base and the lower mold base open the mold. At the same time, the upper mold base drives the side slide to move, so that the side slide and the upper punch are demolded from the laser cutting machine housing.

[0050] Step 7: The die-casting machine drives the first ejector plate and the first drive plate to move up, so that the inclined insert is demolded from the laser cutting machine housing and the first ejector pin pushes the laser cutting machine housing out for feeding.

[0051] Step 8, repeat steps 2-7 to continuously die-cast the laser-cut machine housing.

[0052] The beneficial effects of the die-casting method for laser cutting machine housing provided by the present invention are as follows: Compared with the prior art, by using a die-casting mold for laser cutting machine housing, the laser cutting machine housing and the internal installation protrusion structure can be completed in one die-casting operation. The hole structure is set by using pre-set metal embedded parts. This not only shortens the production time of laser cutting machine housing, but also ensures that the hole positions meet the geometric and positional accuracy requirements of the design, thereby improving the production yield of laser cutting machine housing. It is particularly suitable for mass production operations. Attached Figure Description

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0081] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0082] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0083] Please refer to the following: Figures 2 to 16 The die-casting mold 100 for a laser cutting machine housing provided in this application embodiment will now be described. The die-casting mold 100 for a laser cutting machine housing includes a lower mold base 10 and an upper mold base 20.

[0084] The lower mold base 10 has a lower mold core 11 at its top, and the upper mold base 20 is movably mounted on the top of the lower mold base 10. The upper mold base 20 has an upper mold core 21 at its bottom. The lower mold core 11 has a lower punch 111 at its top, and the upper mold core 21 has an upper punch 211 at its bottom. The lower mold base 10 has a side slide 30 movably mounted on the side of the lower punch 111. When the upper mold base 20 is closed relative to the lower mold base 10, the lower punch 111, the upper punch 211, and the side slide 30 can enclose the mold. The forming chamber 40 of the die-casting laser cutting machine housing 200 is provided with a first forming notch 112 on the front and rear sides of the lower punch 111. The first forming notch 112 penetrates the upper surface of the lower punch 111 and is connected to the forming chamber 40. The bottom of the upper mold core 21 is provided with a forming insert 212. When the upper mold base 20 moves down relative to the lower mold base 10 to complete the mold closing, the forming insert 212 can be inserted into the first forming notch 112 and die-cast to install the protrusion 2001.

[0085] Specifically, by setting a lower punch 111, an upper punch 211, and a side slide 30, a forming chamber 40 for die-casting the laser cutting machine housing can be constructed; and a first forming notch 112 is set on both the front and rear sides of the upper punch 211, which, together with the forming insert 212 structure, can complete the die-casting of the mounting protrusion 2001 on the inner side of the laser cutting machine housing 200. This mechanism simplifies the forming process of the laser cutting machine housing 200, eliminating the need for subsequent CNC milling of the mounting protrusion 2001, thereby shortening production time and improving production efficiency; on the other hand, the mounting protrusion 2001 can be die-cast with the laser cutting machine housing 200 in one go, ensuring that the position of the mounting protrusion 2001 meets the design requirements, thus improving the production yield of the laser cutting machine housing 200.

[0086] Please refer to the following: Figures 2 to 9 In some embodiments, the lower surface of the upper mold core 21 is provided with multiple gating channels 22, one end of which extends toward and connects to the molding chamber 40; the upper mold base 20 is provided with a sprue sleeve 23, which is connected to the other end of the multiple gating channels 22. By setting multiple gating channels, the fluidity can be improved, ensuring that the molten metal can be smoothly injected into the molding chamber 40, thereby improving the die-casting yield of the laser cutting machine housing 200.

[0087] Specifically, the lower mold base 10 is provided with a first ejector plate 12 that can move up and down. The upper surface of the first ejector plate 12 is provided with a first ejector pin 121. The first ejector pin 121 extends upward to the bottom of the first forming notch 112 and is driven by the first ejector plate 12 to extend and retract within the first forming notch 112. At least the top of the first ejector pin 121 is a cylindrical support portion 122. The cylindrical support portion 122 is detachably mounted with a metal embedded part 50. The bottom of the forming insert 212 is provided with a circular limiting hole 2121 for the cylindrical support portion 122 to be inserted. When the upper mold base 20 moves down and closes with the lower mold base 10, the cylindrical support portion 122 can be inserted into the circular limiting hole 2121 and the bottom of the forming insert 212 presses against the metal embedded part 50.

[0088] Please refer to the following: Figure 8More specifically, the first ejector pin 121 includes a lower needle body 1211 and an upper needle body 1212. The bottom of the lower needle body 1211 is fixedly installed on the upper surface of the first ejector pin plate 12, and the bottom of the upper needle body 1212 is rotatably installed on the top of the lower needle body 1211. The top of the upper needle body 1212 is a cylindrical support portion 122, which is a hollow tubular structure and forms a first through cavity 1221. The side of the cylindrical support portion 122 is provided with a conductive connection to the first through cavity 122. The first window 1222 and the first through cavity 1221 of the first window 1222 are equipped with a limiting ball 1223. The limiting ball 1223 can extend downward from the first window 1222 through the action of the elastic rubber 1224. The diameter of the limiting ball 1223 is larger than the diameter of the first window 1222. The metal embedded part 50 has a hole 51 that penetrates its upper and lower surfaces. When the cylindrical support part 122 is inserted into the hole 51, the limiting ball 1223 can abut against the surface of the hole 51.

[0089] Preferably, the rotatable mounting structure between the upper needle body 1212 and the lower needle body 1211 is as follows: the lower needle body 1211 is configured as a whole with a hollow mounting through hole 1213, and a clearance hole 1214 smaller than the mounting through hole 1213 is provided on the top of the lower needle body 1211; then a connecting post 1215 is provided at the bottom of the upper needle body 1212, and an external thread is provided on the outer surface of the connecting post 1215; a rotation limiting block 1216 is provided, and a threaded hole penetrating its upper and lower surfaces is provided on the rotation limiting block 1216. The rotation limiting block 1216 is pushed upward from the bottom of the mounting through hole 1213, and then the connecting post 1215 is inserted from the clearance hole 1214 and screwed into the threaded hole, thus completing the installation of the upper needle body 1212 and the lower needle body 1211.

[0090] Please refer to the following: Figures 7 to 8 and Figures 14 to 16 It should be noted that when feeding the metal embedded part 50, the cylindrical support part 122 is inserted into the hole 51 of the metal embedded part 50, and the limiting ball 1223 abuts against the hole 51 to maintain the position of the metal embedded part 50, so as to prevent the position of the metal embedded part 50 from deviating during the mold closing process. After the metal embedded part 50 is installed on the cylindrical support part 122, the top of the cylindrical support part 122 protrudes from the metal embedded part 50. After the upper mold base 20 and the lower mold base 10 are closed, the top of the cylindrical support part 122 can be inserted into the circular limiting hole 2121 of the forming insert 212, and the bottom of the forming insert 212 and the bottom of the first forming notch 112 together press the metal embedded part 50, and prevent the molten metal from flowing into the hole 51 when the molten metal is injected later, thereby ensuring that the geometric accuracy and positional accuracy of the hole 51 meet the design requirements and improving the production yield of die casting.

[0093] In other embodiments, the right side slide 34 is provided with a first mounting cavity 344, which extends to the left through the surface of the third die portion 342 and to the right through the right surface of the right side slide 34. The first mounting cavity 344 is provided with an upper clamping block 3431, a driving block 3432 and a lower clamping block 3433 from top to bottom. The lower clamping block 3433 is fixedly mounted on the right side movable seat 341.

When the right side movable seat 341 moves to the left, the driving block 3432 can move closer to the upper clamping block 3431 and the lower clamping block 3433 in conjunction with each other.

[0094] Specifically, the upper and lower surfaces of the drive block 3432 are provided with drive ramps 3434. The drive ramps 3434 are inclined from right to left toward the center of the drive block 3432. The drive ramps 3434 are provided with T-shaped drive parts 3435.

The ramps are provided with T-shaped grooves 3436 for the T-shaped drive parts 3435 to slide. When the drive block 3432 moves to the right, the upper clamping block 3431 and the lower clamping block 3433 can move relative to each other through the T-shaped drive parts 3435 and the T-shaped grooves 3436 to complete the demolding of the right window 2005 in the vertical direction. This structure can reduce the wear between the right punch and the right window 2005 during demolding, and can improve the service life of the right punch. At the same time, it can shorten the time required for subsequent grinding and polishing of the right window 2005, and can ensure that the geometric accuracy and positional accuracy of the right window 2005 meet the design requirements.

[0095] More specifically, the front movable seat 311 is provided with a front guide hole 3111 that penetrates its upper and lower surfaces and slopes from bottom to top and rear; the bottom of the upper mold base 20 is provided with a front inclined rod 241 that can be inserted into the front guide hole 3111. The rear movable seat 321 is provided with a rear guide hole 3211 that penetrates its upper and lower surfaces and slopes from bottom to top and forward; the bottom of the upper mold base 20 is provided with a rear inclined rod 242 that can be inserted into the rear guide hole 3211.

Rod 243; The right movable seat 341 is provided with a right guide hole 3411 that runs through the upper and lower surfaces and tilts from bottom to top and to the left. The bottom of the upper mold base 20 is provided with a right inclined rod 244 that can be inserted into the right guide hole 3411. The path of the upper mold base 20 relative to the lower mold base 10 is defined as the first axis b1, the extension direction of the left inclined rod 243 is the second axis b2, the extension direction of the right inclined rod 244 is the third axis b3, the first axis b1 and the second axis b2 form a first angle a1, the first axis b1 and the third axis b3 form a second angle a2, and the second angle a2 is greater than the first angle a1.

[0096] Preferably, the first angle is 18 to 22 degrees, the second angle is 20 to 25 degrees, and the angles of the front diagonal bar 241 and the rear diagonal bar 242 are the same as the angle of the left diagonal bar 243. The front inclined rod 241, rear inclined rod 242, left inclined rod 243, and right inclined rod 244 have the same diameter. The diameter of the left guide hole 3311 is larger than that of the right guide hole 3411. The diameter of the right guide hole 3411 and the right inclined rod 244 are in clearance fit. The diameters of the front guide hole 3111 and the rear guide hole 3211 are the same as those of the left guide hole 3311. With this structure, during the mold opening process of the upper mold base 20, the right moving seat 341 is first driven to move by the right inclined rod 244, so that the driving block 3432 moves in conjunction with the upper clamping block 3431, the lower clamping block 3433, and the right slide 34 to demold. Then, the front inclined rod 241, rear inclined rod 242, and left inclined rod 243 move in conjunction with the front moving seat 311, the rear moving seat 321, and the left moving seat 331 to complete the demolding operation of the front slide 31, the rear slide 32, and the left slide 33.

[0097] It should be noted that the upper mold base 20 is equipped with a shovel 25 corresponding to the front movable base 311, the rear movable base 321, the left movable base 331 and the right movable base 341. The shovel 25 can assist in pushing the front movable base 311, the rear movable base 321, the left movable base 331 and the right movable base 341 to move and close the mold.

[0098] Furthermore, the lower punch 111 has an inclined insert 14 on its left side, which can move obliquely upward to the right. The left side of the inclined insert 14 has a fourth punch portion 141 for the inner recess 2006 on the left inner surface of the laser cutting machine housing 200 for die casting. The lower mold base 10 has a first drive plate 142 that can move up and down. The first ejector plate 12 and the first drive plate 142 are stacked on top of each other. The bottom of the inclined insert 14 is pivotally connected to the first drive plate 142. The path of the inclined insert 14 moving obliquely upward is defined as the fourth axis b4. The fourth axis b4 and the first axis b1 form a third angle a3, which is smaller than the first angle a1 and the second angle.

[0099] Preferably, the third angle is 4 to 6 degrees. When the upper mold base 20 moves up and down to the lower mold base 10, and the upper punch 211, the front slide 31, the rear slide 32, the left slide 33 and the right slide 34 are demolded, the first drive plate 142 and the first ejector plate 12 move synchronously, so that the inclined insert 14 moves diagonally upward to the right while the first ejector pushes straight upward. The inclined insert 14 can provide a certain clearance space for the laser cutting machine housing 200 to be ejected, which is conducive to the first ejector pushing it out.

[0100] Understandably, the first ejector plate 12 is also provided with a second ejector 123 and a third ejector 124, etc. By setting the second ejector 123 and the third ejector 124, they can abut against other positions of the laser cutting machine housing 200 and the material position of the flow channel, so as to improve the smoothness of the ejection of the laser cutting machine housing 200, and also to clean the metal material in the forming chamber 40 and the pouring flow channel 22 as much as possible, so that the laser cutting machine housing 200 can be continuously die-cast without manual cleaning.

[0101] More specifically, the front slide 31, rear slide 32, left slide 33 and right slide 34 are all provided with locking notches 36 at their tops, and the bottom of the upper mold core 21 is provided with locking protrusions 213 that can be inserted into the locking notches 36. When the upper mold base 20 and the lower mold base 10 are closed, the locking protrusions 213 can be inserted into the locking notches 36 to lock the specific positions of the front slide 31, rear slide 32, left slide 33 and right slide 34, so as to improve the reliability of the subsequent metal liquid injection molding chamber 40 die casting to form the laser cutting machine housing 200.

[0102] It should be noted that one of the four corners of the upper mold base 20 and the lower mold base 10 is provided with a guide rod, and the other is provided with a guide hole. The guide rod is inserted into the guide hole to restrict the upper mold base to move only up or down relative to the lower mold base 10.

[0103] In other embodiments, a die-casting method for a laser cutting machine housing is also provided, for producing a laser cutting machine housing 200 using a die-casting mold 100 for the laser cutting machine housing, the die-casting method comprising the following steps:

[0104] Step 1: Provide a die-casting mold 100 for the laser cutting machine housing, and install the die-casting mold 100 for the laser cutting machine housing onto the die-casting machine;

[0105] Step 2: The die-casting machine drives the upper mold base 20 to move, so that the upper mold base 20 and the lower mold base 10 open the mold.

[0106] Step 3: Provide the metal embedded part 50 and install the metal embedded part 50 into the cylindrical support part 122;

[0107] Step 4: The die-casting machine drives the upper mold base 20 to move and close with the lower mold base 10, forming the cavity 40 by the upper punch 211, the lower punch 111, the forming insert 212 and the side slide.

[0108] Step 5: Provide molten metal and inject it from the sprue sleeve 23 through the injection system of the die casting machine, and inject it into the molding chamber 40 through the gating channel 22; after the molten metal cools and solidifies, it is die-cast into the laser cutting machine housing 200 and the mounting protrusion 2001, and the metal of the mounting protrusion 2001 can cover the metal embedded part 50.

[0109] Step 6: The die-casting machine drives the upper mold base 20 to move, so that the upper mold base 20 and the lower mold base 10 open the mold. At the same time, the upper mold base 20 drives the side slide to move, so that the side slide and the upper punch 211 are demolded from the laser cutting machine housing 200.

[0110] Step 7: The die-casting machine drives the first ejector plate 12 and the first drive plate 142 to move upward, so that the inclined insert 14 is demolded from the laser cutting machine housing 200 and the first ejector 121 pushes the laser cutting machine housing 200 out for feeding.

[0111] Step 8, repeat steps 2-7 to continuously die-cast the laser-cut machine housing 200.

[0112] Specifically, in steps 2 to 3, before loading and assembling the metal embedded part 50, a water-based or oil-based release agent needs to be sprayed onto the surfaces of the upper mold core 21 and the lower mold core 11 that participate in the metal liquid forming. After the water-based or oil-based release agent spraying is completed, the metal embedded part 50 is then installed into the cylindrical support part 122.

[0113] It should be noted that the metal material of the embedded metal part 50 may be the same as or different from the metal material of the laser cutting machine housing 200. When manufacturing the embedded metal part 50, it is preferable to use a square, prismatic, or trapezoidal shape to improve the reliability of the embedding between the embedded metal part 50 and the laser cutting machine housing 200. Furthermore, the embedded metal part 50 needs to have holes 51 pre-machined through its upper and lower surfaces using CNC machining, and these holes 51 can be replaced with screw holes according to actual production needs.

[0114] Understandably, when the metal embedded part 50 is assembled, the limiting ball 1223 abuts against the bottom of the hole 51, and this structure facilitates subsequent demolding operations; when the metal embedded part 50 is a screw hole, the limiting ball 1223 abuts against the bottom groove of the screw hole.

[0115] Specifically, in step 6, the position of the upper mold base 20 and the lower mold base 10 when they are closed is defined as 0mm. During the process of the die-casting machine driving the upper mold base 20 to move 4mm upward from 0mm, the right-side inclined rod 244 acts to move the right-side moving seat 341 to the right, and through the right-side moving seat 341 moving to the right, the driving block 3432 moves horizontally to the right. The driving block 3432 can move relative to the upper clamping block 3431 and the lower clamping block 3433 and demold the right window 2005 of the laser cutting machine housing 200. During the process of the upper mold base 20 continuing to move upward, the front inclined rod 241, the rear inclined rod 242, the left inclined rod 243 and the right inclined rod 244 can simultaneously act to move the front sliding position 31, the rear sliding position 32, the left sliding position 33 and the right sliding position 34 respectively, so that it is completely demolded from the laser cutting machine housing 200.

[0116] Understandably, the front side of the lower punch and the front slide are used for die casting the front plate of the laser cutting machine housing, the rear side of the lower punch and the rear slide are used for die casting the rear plate of the laser cutting machine housing, the left side of the lower punch and the left slide are used for die casting the left plate of the laser cutting machine housing, and the right side of the lower punch and the right slide are used for die casting the right plate of the laser cutting machine housing. The front plate, rear plate, left plate and right plate are integrally die cast.

[0117] The above are merely preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way.
