Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing edge blades of push bucket corners, in particular to a die-casting die for special-shaped edge blades. Background Art

[0002] Special-shaped corner blades are generally used in the position of the bulldozer or grader bucket to protect the main blade or bucket side plate on the bucket. They are special-shaped plates with basically the same thickness and an outer contour similar to a spatial quadrilateral, one corner of which is tilted upward, so that the height of one side of the corner gradually increases, and the height of the other side half gradually increases; it can also be said that the position of one plate surface near one corner of the special-shaped corner blade has a protrusion, and the position of the other plate surface near the corner has a recess. The molding method is generally manufactured by die-casting. During manufacturing, the die-casting mold needs to be assembled on a hydraulic press. However, an existing die-casting mold can only die-cast one forging, and in order to ensure the position and size of the forging, the mold also has a molding cavity. In order to ensure that the forging is smoothly taken out of the molding cavity, it is also necessary to set an ejection mechanism, etc., which makes the die-casting mold structure more complicated. Furthermore, in order to manufacture the left and right symmetrical special-shaped edge blades using this die-casting mold, two sets of die-casting molds with relatively complex structures are required, resulting in high costs, and frequent replacement of die-casting molds also affects production efficiency.

[0003] To this end, we designed a die-casting mold that can produce two types of special-shaped edge blades by simply replacing some parts. Utility Model Content

[0004] In order to overcome the shortcomings of the background technology, the utility model discloses a die-casting mold for a special-shaped edge plate.

[0005] In order to achieve the above-mentioned invention object, the utility model adopts the following technical solutions:

[0006] A die-casting mold for a special-shaped edge plate, comprising:

[0007] An upper mold plate, the lower plate surface of which is equipped with a replaceable solid mold, the bottom surface of which has a protrusion matching the special-shaped corner blade plate;

[0008] The lower mold plate has an upper plate surface on which a replaceable movable mold corresponding to the replaceable fixed mold is installed, and the top surface of the replaceable movable mold has a recessed portion matching the special-shaped corner blade plate; the upper plate surface of the lower mold plate is installed with a shift plate strip with adjustable lateral position, and the inner side surfaces of the two shift plate strips are respectively corresponding to and in contact with the two side wall surfaces of the replaceable movable mold away from the recessed portion;

[0009] Wherein, the inner side surface of the shift plate strip is higher than the corresponding side wall surface of the replaceable movable mold.

[0010] Preferably, the shift plate strip is provided with at least two waist-shaped grooves spaced apart along its longitudinal direction, and the waist-shaped grooves are arranged transversely along the shift plate strip;

[0011] The stop plate strip is connected to the upper plate surface of the lower template by bolts with the screw rod part penetrating the waist-shaped groove.

[0012] Preferably, the upper plate surface of the lower template corresponds to the position of the shift strip or the lower plate surface of the shift strip is embedded with a first adsorption component that can be adsorbed on the upper plate surface of the lower template.

[0013] Preferably, the top surface of the replaceable solid mold is in contact with the lower surface of the upper mold plate.

[0014] Preferably, the bottom surface of the replaceable movable mold is in contact with the upper surface of the lower mold plate.

[0015] Preferably, a second adsorption component capable of being adsorbed on the upper surface of the lower template is embedded in the position of the upper surface of the lower template corresponding to the replaceable movable mold or in the bottom surface of the replaceable movable mold.

[0016] Preferably, a third adsorption component is embedded in the position of the lower plate surface of the upper template corresponding to the replaceable solid mold or the top surface of the replaceable solid mold.

[0017] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0018] 1. Only by replacing the replaceable fixed mold and the replaceable movable mold can the special-shaped edge blade of another structure be produced, which saves production costs compared with the existing technology;

[0019] 2. Due to the setting of the position and height of the shift plate, combined with the structure of the replaceable movable mold, the raw materials to be die-cast can be automatically moved to the appropriate position, without the need for the staff to spend time deliberately positioning the raw materials to be die-cast, which not only improves production efficiency but also reduces the skill requirements of the staff; and the formed special-shaped corner blade is located at the top of the replaceable movable mold and can be directly removed without the need for an ejection structure, thus simplifying the structure of the mold;

[0020] 3. The setting of the first adsorption member or the second adsorption member can preliminarily fix the corresponding components and improve the installation accuracy;

[0021] 4. The setting of the third adsorption part can effectively prevent the replaceable solid mold from falling. Compared with no third adsorption part, it frees up one hand of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", etc. to indicate directions or positional relationships, they only correspond to the drawings of the present application, in order to facilitate the description of the present invention; it should be understood that if there are terms such as "end", "side", "end part", "lateral", "lateral", "transverse", "longitudinal", etc. to indicate directions or positional relationships, they only correspond to the length and width of the corresponding parts, that is, "end part" indicates the head and tail areas in the length direction of the corresponding part, and "side part" indicates the head and tail areas in the width direction of the corresponding part; this is for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific direction.

[0029] Embodiment 1, in combination with the attached Figure 3-5 A die-casting mold for a special-shaped corner blade plate comprises an upper mold plate 1 and a lower mold plate 3. A replaceable solid mold 2 is installed on the lower plate surface of the upper mold plate 1, and the bottom surface of the replaceable solid mold 2 has a protrusion 21 matching the special-shaped corner blade plate; a replaceable movable mold 4 corresponding to the replaceable solid mold 2 is installed on the upper plate surface of the lower mold plate 3, and the top surface of the replaceable movable mold 4 has a recessed portion 41 matching the special-shaped corner blade plate; that is, a molding space with the same structure as the special-shaped corner blade plate to be produced can be formed between the replaceable solid mold 2 and the replaceable movable mold 4.

[0030] As required, the replaceable solid mold 2 is detachably mounted on the lower plate surface of the upper mold plate 1 by means of screws; the replaceable movable mold 4 is detachably mounted on the upper plate surface of the lower mold plate 3 by means of screws. Specifically, the positions of the mounting screws of the replaceable solid mold 2 and the replaceable movable mold 4 do not affect the positions of the forming and forming quality of the special-shaped corner blade plate. For example, it is possible to avoid welding fixed ear plates on the sides of the replaceable solid mold 2 and the replaceable movable mold 4, and the fixed ear plates are mounted on the corresponding mold plates by means of screws; for another example, mounting countersunk holes can be opened in the horizontal area of ​​the bottom surface of the replaceable solid mold 2 and the horizontal area of ​​the top surface of the replaceable movable mold 4; it should be noted that the countersunk holes should be away from the protrusions 21 or recesses 41 of the corresponding molds, so as to avoid the positions where stress is concentrated during the die-casting process of the raw materials to be die-cast.

[0031] A shifting strip 5 with adjustable transverse position is installed on the upper plate surface of the lower mold plate 3, and the inner side surfaces of the two shifting strips 5 correspond to and fit with the two side walls of the interchangeable movable mold 4 away from the recessed portion 41 respectively; the inner side surfaces of the shifting strips 5 are higher than the corresponding side walls of the interchangeable movable mold 4; that is, the shifting strips 5 can block and position the raw materials to be die-cast.

[0032] As needed, the stop plate 5 is provided with at least two waist-shaped grooves 51 spaced apart along its longitudinal direction, and the waist-shaped grooves 51 are arranged transversely along the stop plate 5; the stop plate 5 is connected to the upper plate surface of the lower template 3 by bolts with the screw portion passing through the waist-shaped grooves 51.

[0033] It should be noted that: to produce the special-shaped edge and corner blades with symmetrical left and right structures, two replaceable fixed molds 2 and two replaceable movable molds 4 are required.

[0034] In order to increase the strength of the replaceable solid mold 2 and prevent the replaceable solid mold 2 from deforming, the top surface of the replaceable solid mold 2 is fitted with the lower plate surface of the upper mold 1. In other words, the replaceable solid mold 2 and the upper mold 1 have a contact stress that fully covers the top surface of the replaceable solid mold 2, so the replaceable solid mold 2 will not deform.

[0035] In order to increase the strength of the replaceable movable mold 4 and prevent the replaceable movable mold 4 from deforming, the bottom surface of the replaceable movable mold 4 is in contact with the upper surface of the lower mold plate 3. In other words, the replaceable movable mold 4 and the lower mold plate 3 have a contact stress that fully covers the bottom surface of the replaceable movable mold 4, so the replaceable movable mold 4 will not deform.

[0036] When in use, first place the raw material to be die-cast on the top surface of the interchangeable movable mold 4. At this time, under the action of the upwardly tilted edge of the interchangeable movable mold 4, the raw material to be die-cast moves toward the two shift strips 5 until it is blocked by the shift strips 5, so that the raw material to be die-cast is in place, and can be die-cast at this time. When producing another structure of special-shaped edge blades; first disassemble the interchangeable solid mold 2, the interchangeable movable mold 4 and the shift strips 5, then install the interchangeable solid mold 2 first, and then place the interchangeable movable mold 4 in a roughly suitable position on the upper plate surface of the lower mold 3, and then use the hydraulic press to lower the upper mold 1, and make the interchangeable solid mold 2 press the interchangeable movable mold 4, and then knock the interchangeable movable mold 4 to make the recessed portion 41 of the interchangeable movable mold 4 fit with the protruding portion 21 of the interchangeable solid mold 2; then it can be divided into the following installation methods: 1. First take the shift strips 5 so that the shift strips 5, the inner side surface of the shift plate 5 is fitted with the corresponding side wall surface of the replaceable fixed mold 2, and then the shift plate 5 is installed on the upper plate surface of the lower mold plate 3. Specifically, the bolts can be tightened with an elbow wrench to fix the shift plate 5, and then the upper mold plate 1 is raised by a hydraulic press, and then the replaceable movable mold 4 is installed and fixed; 2. First, the upper mold plate 1 is raised by a hydraulic press, and the replaceable movable mold 4 is installed and fixed, and then the shift plate 5 is taken, so that the inner side surface of the shift plate 5 is fitted with the corresponding side wall surface of the replaceable fixed mold 2, and then the shift plate 5 is installed on the upper plate surface of the lower mold plate 3.

[0037] As needed, during the die-casting process, the shift strip 5 is never in contact with the upper mold plate 1, that is, the thickness of the shift strip 5 is less than the sum of the thicknesses of the replaceable solid mold 2, the replaceable movable mold 4 and the special-shaped edge and corner blade plate after molding; preferably, the thickness of the shift strip 5 is less than the thickness of the assembly after the recessed portion 41 of the replaceable movable mold 4 and the protruding portion 21 of the replaceable solid mold 2 are fitted together.

[0038] It should be noted that when replacing the replaceable fixed mold 2 and the replaceable movable mold 4, the shifting strip 5 does not need to be disassembled, and it is only necessary to loosen the shifting strip 5.

[0039] In this embodiment, it is only necessary to replace the replaceable fixed mold 2 and the replaceable movable mold 4 to produce a special-shaped edge and corner blade plate of another structure, which saves production costs compared to the prior art.

[0040] Due to the setting of the position and height of the shifting slat 5 and the structure of the interchangeable movable mold 4, the raw materials to be die-cast can be automatically moved to the appropriate position, without the need for staff to spend time deliberately positioning the raw materials to be die-cast, which not only improves production efficiency but also reduces the skill requirements of staff.

[0041] Embodiment 2, combined with the attached Figure 3-5, a die-casting mold for a special-shaped edge and corner blade plate, based on the first embodiment, the upper plate surface of the lower template 3 corresponds to the position of the gear strip 5 or the lower plate surface of the gear strip 5 is embedded with a first adsorption component (not shown in the figure) that can be adsorbed on the upper plate surface of the lower template 3; that is, when replacing the replaceable fixed mold 2 and the replaceable movable mold 4, and in the process of installing the gear strip 5 first and then installing the replaceable movable mold 4, the first adsorption component can be used to preliminarily fix the position of the gear strip 5, and then after the upper template 1 is raised, the position of the gear strip 5 is locked, making the operation of locking the gear strip 5 more convenient.

[0042] As required, the first adsorption member may be a permanent magnet, an electromagnet and a vacuum suction cup, preferably, an electromagnet is used.

[0043] Embodiment 3, in combination with the attached Figure 3-5 , a die-casting mold for a special-shaped edge blade, based on the first embodiment, the upper plate surface of the lower mold plate 3 corresponds to the position of the replaceable movable mold 4 or the bottom surface of the replaceable movable mold 4 is embedded with a second adsorption component (not shown in the figure) that can be adsorbed on the upper plate surface of the lower mold plate 3; that is, when the replaceable solid mold 2 and the replaceable movable mold 4 are replaced, the second adsorption component can be used to preliminarily fix the position of the replaceable movable mold 4 to prevent the position of the replaceable movable mold 4 from changing when the replaceable solid mold 2 is separated from the replaceable movable mold 4.

[0044] In order to reduce the number of second adsorption components used, the second adsorption components are embedded in the upper surface of the lower template 3 .

[0045] As required, the second adsorption member may be a permanent magnet, an electromagnet and a vacuum suction cup, preferably, an electromagnet is used.

[0046] Embodiment 4, in combination with the attached Figure 3-5 , a die-casting mold for a special-shaped edge and corner blade, based on any one of embodiments one to three, a third adsorption component (not shown in the figure) is embedded in the position of the lower plate surface of the upper mold plate 1 corresponding to the replaceable solid mold 2 or the top surface of the replaceable solid mold 2; specifically, the adsorption force of the third adsorption component is greater than the gravity of the replaceable solid mold 2; that is, only under the action of the third adsorption component, the replaceable solid mold 2 can be fixed to the lower plate surface of the upper mold plate 1.

[0047] In order to reduce the number of third adsorption components used, the third adsorption components are embedded in the lower surface of the upper template 1 .

[0048] This arrangement can effectively prevent the replaceable solid mold 2 from falling when the replaceable solid mold 2 is removed. Compared with the case without the third adsorption component, the worker needs to support the replaceable solid mold 2 with one hand and use the other hand to operate the wrench to remove the screws. The screws are easy to scatter after removal, freeing up one hand of the worker.

[0049] As required, the third adsorption member may be a permanent magnet, an electromagnet and a vacuum suction cup, preferably, an electromagnet is used.

[0050] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
