Abstract
Description
Technical Field
[0001] This utility model relates to the field of die-casting machine technology, and more specifically, it relates to a detachable mold device for a steering wheel die-casting machine. Background Technology
[0002] In modern industrial production, die casting technology, with its high efficiency and high precision, is widely used in automobile manufacturing, aerospace, and mechanical electronics. As one of the core components of a car, the quality and performance of the steering wheel directly affect the driver's safety experience. Therefore, the manufacturing process of steering wheels requires strict standards, and the design and use of molds for die casting machines, as key equipment in steering wheel forming, are particularly important.
[0003] For example, the die-casting machine disclosed in application publication number CN110475632A has a casting spoon for drawing molten metal from a melting furnace, an injection sleeve for injecting the molten metal drawn through the casting spoon, an injection plunger that moves forward or backward within the injection sleeve, and an injection cylinder for moving the injection plunger forward or backward. The injection cylinder moves the injection plunger forward, thereby injecting and filling the molten metal contained in the injection sleeve into the cavity of the mold.
[0004] As mentioned above, during the die-casting process, the mold is subjected to high temperature, high pressure, and the impact of molten metal, which can easily lead to problems such as deformation, wear, and blockage. Because the connection between the mold and the die-casting machine is fixed, the mold cannot be disassembled, making timely inspection and maintenance impossible and reducing work efficiency. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a detachable mold device for a steering wheel die-casting machine that can disassemble the mold and improve working efficiency.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A detachable mold device for a steering wheel die-casting machine includes a base fixedly connected to the die-casting machine and a mold base, wherein the mold base is disposed on one side of the base and detachably connected to the base.
[0008] The mold base is equipped with a connecting plate, one side of which is fixedly connected to the mold base, and the other side extends into the base.
[0009] A rod is provided between the connecting plate and the base, the rod including a positioning rod and a cap.
[0010] One end of the positioning rod is placed outside the base, and the other end passes through the base and connecting plate in sequence and is screwed to the cap.
[0011] The mold base is also provided with a snap-fit protrusion, which is fixedly connected to the mold base. The base is provided with a snap-fit groove, and the snap-fit protrusion is placed in the snap-fit groove and inserted into the snap-fit groove.
[0012] The present invention is further configured such that: the base has a receiving cavity for the connecting plate to extend into, and a spring is provided in the receiving cavity, one end of the spring being connected to the inner wall of the receiving cavity and the other end being connected to the connecting plate.
[0013] The present invention is further configured such that: a through hole 1 is provided on the base for the positioning rod to pass through, a through hole 2 is provided on the connecting plate for the positioning rod to pass through, and a limiting cover is provided at one end of the positioning rod, the diameter of the limiting cover and the cap being larger than the diameter of the through hole 1 and the through hole 2.
[0014] The present invention is further configured such that: both through hole one and through hole two are provided with auxiliary grooves, and the outer wall of the positioning rod is provided with a protruding rod that extends into the auxiliary groove, and the protruding rod is connected to the auxiliary groove.
[0015] The present invention is further configured such that: the outer wall of the positioning rod is provided with an external thread, and the cap is provided with a groove for one end of the positioning rod to extend into, and the inner wall of the groove is provided with an internal thread that is helically connected to the external thread.
[0016] The present invention is further configured such that: there are two snap-fit protrusions, which are placed on both sides of the connecting plate; and there are two snap-fit grooves, which are placed on both sides of the receiving cavity.
[0017] By adopting the above technical solution, the beneficial effects of this utility model are as follows:
[0018] When removing the mold base from the base, rotate the cap, causing the internal and external threads to rotate, thus disengaging the cap from the positioning rod. Then push the positioning rod, causing the protrusions on the positioning rod to simultaneously disengage from the protrusions on through hole one and through hole two. Next, pull the positioning rod outward, and it will pass through through hole one, through hole two, and the receiving cavity in sequence. Pry the mold base upward, and the snap-fit protrusion on the mold base will disengage from the snap-fit groove. At this point, the connecting plate will separate from the spring, and the mold base and the base will be in a separated state. Through the rod, snap-fit protrusion, and snap-fit groove, the mold can be quickly disassembled and replaced, and the mold can be inspected and repaired in a timely manner, thereby improving work efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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 utility model.
[0025] like Figures 1 to 3 As shown, the detachable mold device for the steering wheel die-casting machine includes a base 1 and a mold seat 2. The base 1 is fixed to the die-casting machine by welding. One side of the connecting plate 3 is integrally formed with the mold seat 2, and the other side of the connecting plate 3 extends into the receiving cavity 8 and abuts against one end of the spring 9. The other end of the spring 9 is fixed to the bottom surface of the inner wall of the receiving cavity 8.
[0026] When the mold base 2 is pressed down in the direction of the downward receiving cavity 8, the spring 9 is compressed. The two snap-fit protrusions 6 on the mold base 2 are compressed and engaged with the two snap-fit grooves 7 on the base 1, thus achieving the first fixation between the base 1 and the mold base 2. Since there are two snap-fit protrusions 6 and two snap-fit grooves 7, and the two snap-fit protrusions 6 correspond one-to-one with the two snap-fit grooves 7, the base 1 and the mold base 2 are more stable.
[0027] When base 1 and mold base 2 are aligned, the connecting plate 3 and the through hole on base 1 are also flush.
[0028] Both snap-fit protrusions 6 are integrally formed with the mold base 2. The positioning rod 4 passes through the through hole 12 on one side of the base 1, is placed in the receiving cavity 8, then passes through the through hole 13 on the connecting plate 3, is placed in the receiving cavity 8 again, and finally passes out from the other side of the base 1. The positioning rod 4 is moved, and the protrusions 16 on the positioning rod 4 are snapped and fixed in the auxiliary grooves 15 of the through hole 12 and the through hole 13. The base 1 and the connecting plate 3 are fixed through the positioning rod 4, which further enables the base 1 and the mold base 2 to be fixed a second time. The protrusions 16 on the positioning rod 4 are integrally formed with the positioning rod 4.
[0029] Then, the groove on the cap 5 is fitted onto the positioning rod 4, and the cap 5 is rotated. The internal thread 11 and the external thread 10 are screwed together, and the base 1 and the mold seat 2 are fixed for the third time. Through the three fixations, the base 1 and the mold seat 2 are made more stable.
[0030] Because the diameters of the limiting cover 14 and the cap 5 are larger than the diameter of the through hole, the limiting cover 14 and the cap 5 are stuck outside the base 1.
[0031] Working principle: When the mold base 2 is removed from the base 1, the cap 5 is rotated, and the internal thread 11 and the external thread 10 rotate, causing the cap 5 to rotate out of the positioning rod 4. Then, the positioning rod 4 is pushed, and the protrusion 16 on the positioning rod 4 is simultaneously disengaged from the protrusion 16 on the first through hole 12 and the protrusion 16 on the second through hole 13. Then, the positioning rod 4 is pulled outward, and the positioning rod 4 passes through the first through hole 12, the second through hole 13 and the receiving cavity 8 in sequence. The mold base 2 is pried upward, and the snap-fit protrusion 6 on the mold base 2 is disengaged from the snap-fit groove 7. At this time, the connecting plate 3 is separated from the spring 9, and the mold base 2 and the base 1 are in a separated state, so that the mold can be removed from the die-casting machine. Through the rod, the snap-fit protrusion 6 and the snap-fit groove 7, the mold can be quickly disassembled and replaced, and the mold can be inspected and repaired in a timely manner.
[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
