Description

Technical Field

[0001] The utility model relates to a die-casting part of a server cabinet in the field of mobile communication equipment and its die-casting mold, and is a large die-casting part and its slider shunting mold. Background Art

[0002] A die-casting part is a part formed by die-casting. It uses a die-casting machine, which is a pressure casting machine equipped with a casting mold, to pour molten metals such as copper, zinc, aluminum, or aluminum alloy heated to a liquid state into the feeding port of the die-casting machine. After die-casting by the die-casting machine, copper, zinc, aluminum parts, or aluminum alloy parts with shapes and sizes restricted by the mold are cast. Such parts are usually called die-casting parts. Generally, no pressure is applied to casting parts. The requirements for the strength of equipment and molds are not high, the size limitations of products are small, and the internal stress in the products is also low. Its production investment is less, and large parts with excellent performance can be produced, but the production cycle is long, and machining is required after forming. Based on traditional casting, methods such as pouring, inlay casting, pressure casting, rotary casting, and centrifugal casting are derived. Among them, pressure casting applies a certain pressure to the material during casting, which is beneficial to injecting viscous materials into the mold and shortening the mold filling time. It is mainly used for epoxy resin casting. Some existing tray mechanisms in communication server cabinets generally use such large die-casting parts. For example, the authorization announcement number of the Chinese patent document is CN204031688U, the authorization announcement date is December 17, 2014, and the utility model name is "A New Type of Network Cabinet Tray". In order to facilitate loading and unloading, some of the above cabinet trays can achieve quick loading and unloading of the tray through a fixed plate on one side and a lock at its end corner. For the existing die-casting mold and its shunting cone structure, such as the authorization announcement number of the Chinese patent document is CN220196307U, the authorization announcement date is December 19, 2023, and the utility model name is "A Shunting Cone Cooling Structure on a Die-Casting Mold Slide Block". The molds of the above products and similar products generally use a conical shunting cone with a notch at one end corner on the top. The raw material of its shunting structure is filled in the straight runner. The straight runner can only move vertically and longitudinally and cannot move horizontally, making it difficult to be fixed on a laterally moving slider. Therefore, large die-casting parts cannot be formed on a die-casting machine and its mold. Summary of the Invention

[0003] To overcome the above deficiencies, the purpose of the utility model is to provide a large die-casting part and its slider shunting mold to the field, so as to solve the technical problems that the structure design of large die-casting parts used as the fixed plate of the cabinet tray in existing similar products is not good enough, and the production of large die-casting parts such as the fixed plate of the cabinet tray is relatively inconvenient. In particular, the direct current channel of the mold lacks the design of simultaneous vertical and longitudinal movement, horizontal movement, and lateral movement of the slider, resulting in the inability to form large die-casting parts. Its purpose is achieved through the following technical solutions.

[0004] A large die-cast part, the key point of its structural design is that the die-cast part body of the large die-cast part is in an "E" shape. The die-cast part body is the fixed plates at both ends of the cabinet tray. On one side of the middle of the top of the cross bar of the die-cast part body, there is a first groove bar that is higher and integrally formed. On both sides of the top of the cross bar, there are symmetrically arranged second groove bars and third groove bars that are higher and integrally formed. While one end of the first groove bar, the second groove bar, and the third groove bar are integrally formed with the cross bar respectively, the other ends of the first groove bar, the second groove bar, and the third groove bar extend out of the cross bar and respectively have buckle grooves at the bottom. The top plane of the cross bar is provided with heat dissipation holes and through holes for corresponding equipment. The bottom of the cross bar is provided with a flat bar-shaped tray groove, and installation holes are provided corresponding to the groove bars or the cross bar.

[0005] At one side end corner of the cross bar of the die-cast part body and the corresponding groove bar integrally connected thereto, there is an open lock groove. This facilitates the installation of the lock and makes it flush with the outside, and then the die-cast part body and the tray can be quickly installed through the lock.

[0006] At the end edge of the other groove bar symmetric to the lock groove, there is an open installation groove. At the installation groove and the edge of the corresponding groove bar on one side of the lock groove, there are respectively large installation holes. At the end parts of the first groove bar, the second groove bar, and the third groove bar extending out of the cross bar, there are respectively top installation holes. On the peripheral edge of the cross bar, there are small installation holes.

[0007] In the tray groove at the bottom of the cross bar of the die-cast part body, there are reinforcing ribs that are higher than the bottom notch. One side of the reinforcing ribs of the first groove bar, the second groove bar, and the third groove bar is integrally connected to the inner wall, and the symmetric other side is disconnected and aligned with the inner wall. The above structure facilitates the insertion and fixation of the edge of the interface side of the circuit board into the gap at the disconnected part of the inner wall of the cross bar. The disconnected and integral parts of the inner wall can also be arranged in the reverse direction, and the through holes corresponding to the top plane of the cross bar can be arranged in the reverse direction, and the die-cast part body can be installed in the reverse direction.

[0008] In the buckle grooves at the bottoms of the first groove bar, the second groove bar, and the third groove bar of the die-cast part body, there are respectively protruding buckle ribs, and the wing plates on both sides of the buckle ribs are respectively aligned with the buckle holes at the top planes of the corresponding first groove bar, second groove bar, and third groove bar above.

[0009] According to the structural design features of the above-mentioned die-casting part body, a slider shunt die for large die-castings, the die includes a first slider, a shunt cone body and a die core. The die core includes a support base and a support cover. A shunt cone body integrated together is provided in the middle of the first slider. A first screw hole integrated with the first slider is provided at the bottom of the shunt cone body. At one outer end of the first slider where the protrusion extends out of one side of the die core, a first slide base integrated together through a second screw hole is provided. The other end of the die core on the inner side of the first slider is integrated with a slider groove with an opening at one end angle of the support base. The top plane of the first slider in the die core is flush with the plane at the step above the slider groove of the support base. The top of one side of the first slide base at the connection with the first slider is higher than the top plane of the first slider and is limited to the outer diameter at the connection of the support base and the support cover. The support cover and the support base are covered in alignment through column grooves with corresponding concavities and convexities at the end angles. A die core cavity forming the die-casting part body is provided inside the covered support cover and support base. The die core cavity communicates with the casting hole above the shunt cone body in the support cover through a flow-through groove at the bottom of the support cover on one side of the top plane of the first slider. Water inlets and outlets are respectively provided on the support base, the support cover of the die core and the corresponding slider. The raw material is filled into the flow-through groove and the die core cavity from the casting hole of the support cover. The key point of its structural design is that the shunt cone body is an isosceles triangular prism. Side grooves are symmetrically provided on both rectangular planes on both sides of the integral convex inclined plane at the place where the shunt cone body protrudes above the top plane of the first slider. The side grooves of the shunt cone body are shunt grooves. When the raw material filled into the flow-through groove moves vertically longitudinally from the top of the shunt cone body and then moves horizontally into the die core cavity, at the same time, the raw material passing through the casting hole of the support cover moves vertically longitudinally downward from both integral convex inclined planes on both sides of the shunt cone body. Before the die-casting of the die-casting part body is cooled and formed, the first slide base drives the first slider to move horizontally outwards. The raw material at the connection of the first slider and the support base where the flow-through groove is connected to the die core cavity forms a demolding edge. An opening is provided on the support cover at the flow-through groove on the side where the first slider moves horizontally outwards, and the shape corresponds to the chute hole of the shunt cone body. The casting hole in the support cover increases from top to bottom and is conical to wrap the outer diameter of the integral convex inclined plane of the shunt cone body, and is integrated and communicated with the flow-through groove at the bottom of the support cover. The above structural design of the shunt cone body realizes the shunt of simultaneous horizontal and vertical movements, solves the problem that large die-castings cannot be formed. In the die core cavity of the die, the middle and the convexities on both sides respectively correspond to the first groove rod, the second groove rod and the third groove rod of the die-casting part body. The convexity on one side lower than the three protrusions corresponds to the cross bar of the die-casting part body. The slider moves horizontally in and out of the shunt cone body and the first slider from one side of the chute hole of the support cover. At the same time, the shape of the die core cavity in the die is determined according to the specific shape of the large die-casting, and is not limited to the die-casting part body combined with the above cross bar, first groove rod, second groove rod and third groove rod. Since the wrapping force of the existing shunt cone is less than the wrapping force of the runner in the front die, the runner will stick to the front die, making the die unable to produce. Side grooves need to be added to this shunt cone body. After the product is formed, the first slider moves backward to separate the side grooves of the shunt cone body.

[0010] There is a lower chamfer transition edge that increases outward between the integral convex inclined surface in the middle of the flow dividing cone body and the bottom, and an upper S-shaped transition edge that decreases inward between the integral convex inclined surface in the middle of the flow dividing cone body and the top. On both sides, there are two side grooves arranged vertically and in a straight line at the integral convex inclined surfaces on both sides in the middle of the flow dividing cone body; the width of one end of the side groove on one side where the first slider moves horizontally outward is smaller than that of the symmetric other end, and the depth of one end of the side groove on one side where the first slider moves horizontally outward is greater than that of the symmetric other end. The width of the top and the lower part on the side where the first slider moves horizontally outward of the flow dividing cone body is greater than that of the symmetric other side. The specific structure and shape of the above-mentioned flow dividing cone body ensure that when there is no vertical longitudinal movement and horizontal movement in the DC channel, the raw material moves vertically longitudinally from the top and then enters the die core cavity through the horizontal flow groove.

[0011] The flow grooves at the bottom of the support cover are six in number and flow towards one side of the cross bar for forming the main body of the die-cast part in the die core cavity. On both sides of the first groove bar of the cross bar, two flow grooves are symmetrically arranged. On the second groove bar and the third groove bar on both sides of the cross bar, four flow grooves are symmetrically arranged in pairs respectively; the groove openings of the flow grooves on both sides at the first groove bar are larger than those of the flow grooves at the second groove bar and the third groove bar on both sides of the cross bar. The above structure ensures the stable and uniform inflow of the raw material into the die core cavity during the production and forming process of the main body of the die-cast part.

[0012] At least on both sides of the first slider of the support base, a second slider and a third slider are respectively provided. At the ends of the second slider and the third slider extending out of the die core, a second sliding seat and a third sliding seat are integrally connected respectively. At the other ends of the second slider and the third slider inside the die core, the support base and the support cover form the die core cavity of the main body of the die-cast part. The above structure facilitates die-casting forming on both sides of the second groove bar and the third groove bar and on the outside.

[0013] On the symmetric other side of the first slider of the support base, a third slider and its corresponding fourth sliding seat are provided. Thus, the forming is further realized through the four large sliders.

[0014] The structural design of the present utility model is reasonable, the firmness and stability of the die-cast part are good, the application range is wide, the installation and use are convenient and simple, the opening, closing and parting of the mold are convenient, the vertical longitudinal movement and the horizontal movement of the DC channel in the mold are combined, which is convenient for the horizontal movement of the slider; it is suitable for use in the superheated steam system of cooking appliances such as steam fryers and the structural improvement of similar products.

Large installation holes are respectively provided at the installation groove and the edge of the corresponding groove bar on one side of the lock groove. At the end parts of the first groove bar, the second groove bar, and the third groove bar extending out of the cross bar, there are respectively top installation holes. Small installation holes are provided at the peripheral edge of the cross bar. Inside the support plate groove at the bottom of the cross bar of the main body of the die-casting part, there is a reinforcing rib 1007 that is higher than the bottom notch.

The top of one side of the first sliding seat at the connection of the first sliding seat and the first slider is higher than the top plane of the first slider and is limited by the outer diameter at the connection of the support base and the support cover. The support cover and the support base are covered in alignment through the column grooves with corresponding concavities and convexities at the end angles. Inside the covered support cover and support base, there is a mold core cavity forming the main body of the die-casting part. The mold core cavity communicates with the casting hole 501 of the support cover above the split-flow cone main body through the flow-through groove 502 at the bottom of the support cover on one side of the top plane of the first slider. The support base, the support cover, and the corresponding slider of the mold core are respectively provided with water inlets and water outlets. The raw material 11 is filled into the flow-through groove and the mold core cavity from the casting hole of the support cover.

[0029] The above-mentioned flow-dividing cone body is an isosceles triangular prism. On both sides of the integral convex inclined plane 201 of the flow-dividing cone body protruding from the top plane of the first slider, side grooves 202 are symmetrically arranged on the rectangular planes. The side grooves of the flow-dividing cone body are flow-dividing grooves; when the raw materials filled into the flow-through groove move vertically and longitudinally from the top of the flow-dividing cone body and then move horizontally into the die core cavity, at the same time, the raw materials passing through the casting holes 501 of the support move vertically and longitudinally downward from both sides of the integral convex inclined plane of the flow-dividing cone body. Before the die-casting main body is die-cast and cooled to form, the first slide seat drives the first slider to move horizontally outward. At the connection between the first slider and the support seat at the connection between the flow-through groove and the die core cavity, the raw materials form a parting edge; at the flow-through groove on the side where the first slider moves horizontally outward, the support cover is provided with an opening and a chute hole 503 whose shape corresponds to the flow-dividing cone body. The casting hole in the support cover increases from the top downward in a conical shape to wrap the outer diameter of the integral convex inclined plane of the flow-dividing cone body, and is connected and communicated with the flow-through groove at the bottom of the support cover as a whole.

[0030] An outwardly increasing lower chamfer transition edge is provided between the integral convex inclined plane in the middle of the above-mentioned flow-dividing cone body and the bottom, and an inwardly decreasing upper S-shaped transition edge is provided between the integral convex inclined plane in the middle of the flow-dividing cone body and the top. Two side grooves arranged vertically and in a straight line are respectively arranged on both sides of the integral convex inclined plane in the middle of the flow-dividing cone body; the width of one end of the side groove on the side where the first slider moves horizontally outward is smaller than that of the symmetric other end, the depth of one end of the side groove on the side where the first slider moves horizontally outward is greater than that of the symmetric other end, and the width of the top and the lower part of the flow-dividing cone body on the side where the first slider moves horizontally outward is greater than that of the symmetric other side. The flow-through groove at the bottom of the support cover has six crossbars flowing towards the die core cavity to form the die-casting main body. On both sides of the first groove bar of the crossbar, two flow-through grooves are symmetrically arranged. On the second groove bar and the third groove bar on both sides of the crossbar, four flow-through grooves are respectively arranged in pairs symmetrically; the notch of the flow-through groove on both sides at the first groove bar is larger than the notch of the flow-through groove at the second groove bar and the third groove bar on both sides of the crossbar. At least two sides of the first slider of the support seat are respectively provided with a second slider 6 and a third slider 8. The die core extending ends of the second slider and the third slider are respectively provided with an integrated second slide seat 7 and a third slide seat 9. The other ends of the die cores of the second slider and the third slider inside are connected with the support seat and the support cover to form the die core cavity of the die-casting main body.

[0031] In use, the mold is placed into a mold forming device, and the water inlet pipe and the water outlet pipe are respectively connected to the water inlets and water outlets of the first slider, the second slider, the third slider, the support cover, and the support base. The inclined holes of the first slider, the second slider, and the third slider are respectively provided with actuating inclined struts, or the actuating holes of the first slider, the second slider, and the third slider are respectively connected to the actuating connecting rods. The support cover is covered with the support base through the actuating mechanism of the mold forming device. The raw material is filled through the casting hole of the support cover. Before the main body of the die-casting part is die-cast and cooled to form, the first slider, the second slider, and the third slider respectively move outwards and open the support cover. After the main body of the die-casting part is cooled to the specified temperature, it is taken out, and the main body of the die-casting part can be formed. At the same time, in the above production process, the corresponding slider is pushed as needed to assist the filling effect of the internal raw material to be better. The main body of the die-casting part produced above is obtained as a finished product through deburring, electroplating and other industries, and is installed at one end or both sides of the tray through plates and screws. A lock is installed at the end corner of one side of the main body of the die-casting part. The jacks of the circuit board respectively extend out of the through holes at the cross bar. The module chassis and the like are installed between the first slot bar, the second slot bar, and the third slot bar. The tray is placed into the frame structure in the cabinet through the main body of the die-casting part.

[0032] According to the above structural characteristics, further, a third slider and its corresponding fourth sliding seat are provided on the symmetric other side of the first slider of the above support base.

[0033] To sum up, in the existing shunt structure, the raw material is filled in the straight runner. The straight runner can only move vertically longitudinally and cannot move horizontally, so it cannot be fixed on the laterally moving slider, making it impossible to form large die-cast parts on a die-casting machine. With the large and complex shape and structure of large die-cast parts in related products in industries such as communication server cabinets, three-sided or four-sided large sliders are required to form the product. However, the existing shunt cone and shunt sleeve cannot be fixed on the moving slider, making it impossible to form large die-cast parts on a die-casting machine. This mold relates to a zinc alloy die-casting mold for die-casting molds and its shunt cone, including a shunt cone main body and a shunt cone feeding structure integrally formed with the slider main body and the front mold core; a shunt cone is installed on the slider main body, and side grooves are provided at the integral convex inclined surfaces on both sides of the slider main body to solve the problem that the shunt cone of the three-sided or four-sided slider sucks the front mold product and cannot be formed.

[0034] The above is intended to illustrate the technical means of the present invention and does not limit the technical scope of the present invention. Obvious improvements or replacements made by those skilled in the art to the present invention in combination with the existing common general knowledge also fall within the protection scope of the claims of the present invention.
