Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of die-casting molds, in particular to a middle plate hanging structure of a die-casting mold. Background Art
[0002] Due to the complex structure of automobile parts, die-casting molds are usually used for processing and molding. Due to the special structure of the casting, the die-casting mold needs to adopt a three-plate mold structure. When the mold is opened, the middle plate and the movable mold are pulled together to move away from the fixed mold. When the middle plate moves to the set distance, the middle plate is restricted by the limit mechanism, and then the movable mold continues to move and separates from the middle plate. When the middle plate and the fixed mold are separated, the cake flow channel between the middle plate and the fixed mold is broken and automatically falls off due to gravity. Since the fixed film core, flow channel plate and other parts are set on the middle plate, the overall weight is large, so it is necessary not only to support the middle plate, but also to make the middle plate have the requirement of being able to move laterally. Due to the narrow matching space between the die-casting mold and the die-casting machine, the cost and difficulty of installing hanging tooling on the outside are also high, so it is conceived to use the die-casting machine's own structure to hang the middle plate on the beam of the die-casting machine. Utility Model Content
[0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a middle plate hanging structure for a die-casting mold, so that the middle plate can be reliably set on the lever beam of the die-casting machine.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] The middle plate hanging structure of the die-casting mold includes a vertically arranged middle plate and two hanging arms arranged on the top of the middle plate. The hanging arms are used to be hung on the lever beam of the die-casting machine. The hanging arms are provided with pads for sliding connection with the lever beam of the die-casting machine.
[0006] As a further improvement of the above technical solution, the hanging arm is in a "7" shape, including a vertical seat and a hanging head; the pad is arranged at the bottom of the hanging head.
[0007] As a further improvement of the above technical solution, the cushion block includes an upper mounting block and a lower sliding block, and the upper mounting block is fixed on the hanging head of the hanging arm.
[0008] As a further improvement of the above technical solution, the bottom surface of the lower sliding block forms a positioning arc surface that is compatible with the lever beam of the die-casting machine, and the positioning arc surface extends in the transverse direction.
[0009] As a further improvement of the above technical solution, a lubrication groove line is provided on the positioning arc surface, and an oil delivery channel connected to the interior of the lower slider and penetrating the lubrication groove line is opened on the side of the lower slider.
[0010] As a further improvement of the above technical solution, the lower sliding block is provided with countersunk holes on both sides of the positioning arc surface, and the upper mounting block is provided with threaded holes having the same number as the countersunk holes and corresponding to each other.
[0011] The upper mounting block includes a flat plate portion and a limiting side plate portion which are combined to form an L shape, a laterally extending positioning convex strip is provided in the middle of the flat plate portion, a slot for the positioning convex strip to be embedded in the bottom of the hanging head is provided, the limiting side plate portion is connected to one side surface of the hanging head by screws, and the other end surface of the hanging head and the flat plate portion are connected by a connecting block and screws.

[0015] Beneficial effects of the utility model: The middle plate hanging structure provided by the utility model cleverly uses the lever beam of the die-casting machine to carry the middle plate, thereby enhancing the working stability of the middle plate. The operator only needs to hang two hanging arms on the lever beam of the die-casting machine to complete the installation of the middle plate, without the need for additional adjustments and operating steps, thus reducing the complexity of the operation.

DETAILED DESCRIPTION
[0022] The utility model provides a middle plate hanging structure of a die-casting mold. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the protection scope of the utility model.
[0023] The utility model improves the die-casting mold composed of a fixed mold 11, a middle plate 12 and a movable mold 13. The fixed mold 11 and the movable mold 13 are installed on a mold clamping mechanism 42 of a die-casting machine, and the middle plate 12 is hung on a lever beam 41 of the die-casting machine.
[0024] See also Figure 1-Figure 5 The utility model provides a middle plate 12 hanging structure, including a vertically arranged middle plate 12, two hanging arms 2 arranged on the top of the middle plate 12, the hanging arms 2 are used to be hung on the lever beam 41 of the die-casting machine, and the hanging arms 2 are provided with a pad 3 for sliding connection with the lever beam 41 of the die-casting machine.
[0025] The middle plate 12 hanging structure provided by the utility model cleverly uses the lever beam 41 of the die-casting machine to carry the middle plate 12, thereby enhancing the working stability of the middle plate 12. The operator only needs to hang the two hanging arms 2 on the lever beam 41 of the die-casting machine to complete the installation of the middle plate 12, without the need for additional adjustments and operating steps, thereby reducing the complexity of the operation. When the middle plate 12 is towed and moved, the lever beam 41 slides with the pad 3 on the hanging arm 2, smoothly and unobstructed, thereby reducing the vibration and swing of the middle plate 12 and improving the stability during the working process. Compared with the external installation of hanging tooling, hanging the middle plate 12 on the large bar of the die-casting machine not only reduces costs and processing difficulties, but also saves space to the maximum extent, making the entire working area more compact.
[0026] Specifically, the hanging arm 2 is in a "7" shape, including a vertical seat 21 and a hanging head 22. The vertical seat 21 and the hanging head 22 can be integrally formed by injection molding, and have high structural strength. The bottom of the vertical seat 21 is installed to be larger, and the bottom of the vertical seat 21 and the seat body are connected by reinforcing ribs to improve the structural strength. The bottom of the vertical seat 21 is screwed to the corners of the middle plate 12. That is, the vertical seat 21 serves as the supporting point of the hanging, and the hanging head 22 is connected to the lever beam 41 of the die-casting machine; this structural design enhances the bearing capacity of the hanging arm 2, can better support the weight of the middle plate 12, and improves the stability of the entire hanging system.
[0027] Furthermore, the pad 3 is arranged at the bottom of the hanging head 22. This arrangement can provide a more stable support area, and enhance the connection stability between the hanging arm 2 and the beam 41 of the die-casting machine. This design can reduce vibration and looseness, and ensure the safety and reliability of the hanging structure during operation.
[0028] Specifically, the cushion block 3 includes an upper mounting block 31 and a lower slider 32. The upper mounting block 31 is fixed on the hanging head 22 of the hanging arm 2, and the lower slider 32 is slidably connected with the lever beam 41 of the die-casting machine, which can reduce the friction resistance of the hanging structure during movement, reduce the force required for operation, and improve the convenience and efficiency of operation. It can be seen that the upper mounting block 31 and the lower slider 32 form a layered structure. Even if the lower slider 32 is worn and needs to be replaced, only the lower slider 32 needs to be replaced, and there is no need to replace the entire cushion block 3, which saves maintenance costs. The bottom surface of the lower slider 32 forms a positioning arc surface 33 that is compatible with the lever beam 41 of the die-casting machine, and the positioning arc surface 33 extends in the horizontal direction. The positioning arc surface 33 is compatible with the lever beam 41 of the die-casting machine, which can achieve more accurate positioning and centering, ensure that the hanging structure and the die-casting machine are more closely matched, and improve the accuracy and stability of installation. It also makes the contact between the hanging structure and the lever beam 41 of the die-casting machine smoother during movement, reduces friction and wear, and extends the service life of the hanging structure and the lever beam 41 of the die-casting machine.
[0029] The lower slider 32 is provided with countersunk holes 34 on both sides of the positioning arc surface 33, and the upper mounting block 31 is provided with threaded holes that are the same in number and correspond to the countersunk holes 34. A locking screw is installed at each countersunk hole 34 and screwed into the corresponding threaded hole, so that the upper mounting block 31 and the lower slider 32 are reliably connected, and the head of the locking screw is also hidden in the countersunk hole 34 and will not protrude to interfere with the lever beam 41 of the die casting machine.
[0030] Preferably, a lubrication groove 35 is provided on the positioning arc surface 33. The lubrication groove 35 can store lubricant and automatically release it during the movement of the hanging structure to form a lubrication film, reduce friction and wear between metal parts, and thus improve the lubrication effect. A good lubrication state can reduce the movement resistance of the hanging structure, ensure the stability and stability of the hanging structure during movement, reduce vibration and noise, and improve the operation stability of the equipment. An oil delivery channel that connects to the interior of the lower slider 32 and penetrates the lubrication groove 35 is provided on the side of the lower slider 32, and an oil nozzle 36 is provided at the input end of the oil delivery channel. The staff can regularly add additional lubricating oil to the oil delivery channel and the lubrication groove 35 through the oil nozzle 36.
[0031] Specifically, the upper mounting block 31 includes a flat plate portion 311 and a limiting side plate portion 312 which are combined to form an L shape. A horizontally extending positioning convex strip 313 is provided in the middle of the flat plate portion 311. A slot 221 for the positioning convex strip 313 to be inserted is provided at the bottom of the hanging head 22. The limiting side plate portion 312 is connected to one side of the hanging head 22 by screws, and the other end face of the hanging head 22 and the flat plate portion 311 are connected by a connecting block 37 and screws. The design of the positioning convex strip 313 and the slot 221 ensures accurate alignment between the hanging head 22 and the upper mounting block 31, making the installation more accurate, effectively reducing the error during the installation process, and improving the accuracy and stability of the installation. The connecting block 37 makes up for the connection strength between the limiting side plate portion 312 and the hanging head 22, forming a more solid supporting structure, effectively enhancing the stability and shock resistance of the connection between the hanging head 22 and the upper mounting block 31, reducing the possibility of vibration and looseness, and improving the reliability of the overall hanging structure.
[0032] Preferably, a positioning groove 23 is provided at the bottom of the vertical seat 21, and a positioning block matching the positioning groove 23 is provided on the middle plate 12. The design of the positioning groove 23 and the positioning block ensures the accurate alignment between the vertical seat 21 and the middle plate 12, making the installation more accurate, effectively reducing the error during the installation process, and improving the accuracy and stability of the installation. A tighter connection is formed between the vertical seat 21 and the middle plate 12, which enhances the stability and seismic resistance of the entire hanging structure and reduces the possibility of vibration and looseness.
[0033] In order to arrange the mold temperature oil pipe to form a fixed route, a tube bundle plate 38 for fixing the mold temperature oil pipe is provided on the side of the vertical seat 21. The top of the tube bundle plate 38 is screwed to the vertical seat 21 through a connecting column, and the bottom of the tube bundle plate 38 is directly screwed to the vertical seat 21 through screws.
