Description

Technical Field

[0001] The utility model relates to the technical field of mold frames, in particular to an assembled adjustable mold frame. Background Art

[0002] The mold base is the supporting structure of the mold, composed of various steel plates and components, and serves as the backbone of the entire mold. The mold base includes components such as ejection mechanisms, guides, and pre-reset mechanisms. These components are used to assemble and secure the mold components in a specific pattern and position for installation on the die-casting machine. Mold bases are widely used in industries such as automotive, aerospace, consumer goods, electrical and communications, and medical products. Mold manufacturers typically order mold bases from mold base manufacturers to leverage the production advantages of both parties and improve production quality and efficiency. Standard mold bases offer a wide variety of styles and short delivery times, providing mold manufacturers with greater flexibility. Mold bases come in a variety of forms and configurations. Fixed mold bases are suitable for molds with strong symmetry, while movable mold bases are suitable for applications requiring adjustable mold gaps or ejection clearances. Three-plate mold bases are suitable for molding complex products, while multi-plate mold bases facilitate simultaneous molding at multiple stations. The basic components of a mold base include a base, upper and lower mold plates, guide pins and sleeves, and an opening and closing mechanism. The materials and machining quality of these components directly impact the stability, precision, and reliability of the mold.

[0003] An existing patent document (CN219944569U) discloses a modular mold frame comprising an ejection module, a guide module, a lower plate module, and an upper plate module. Each of these ejection module, guide module, lower plate module, and upper plate module is provided with a snap-on assembly. The guide module extends through the lower plate module and is snap-on to the upper plate module via the snap-on assembly, while the ejection module is snap-on to the lower plate module via the snap-on assembly. This application aims to make mold frame installation more convenient and faster.

[0037] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0038] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate directions or positions are based on the directions or positional relationships shown in the accompanying drawings, which are merely simplified descriptions for the convenience of describing the present invention, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the above terms should not be understood as limitations on the present invention.

[0039] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0040] Example 1: Please refer to Figures 1-8 , an assembled adjustable mold frame shown in the figure includes an upper mold base 1 and a lower mold base 2, and also includes: a spacer plate 3, the spacer plate 3 is fixed to one side of the lower mold base 2, the projected area value of the lower mold base 2 is larger than the projected area value of the upper mold base 1, the cross-section of the spacer plate 3 is concave, and the angle between the spacer plate 3 and the lower mold base 2 is right-angled. The spacer plate 3 is provided to provide structural support for the entire mold frame, ensuring the stability and durability of the mold frame. The spacer plate 3 is used to disperse local loads to prevent deformation. A load-bearing plate 4 is fixed to one side of the spacer plate 3. The load-bearing plate 4 mainly serves to bear various components and pressures in the mold to ensure the stability and safety of the mold;

[0041] The template 5 is fixed to one side of the bearing plate 4, and a guide rod 12 is fixed to the top of the template 5. The number of guide rods 12 is preferably four. A hole groove 13 is provided on one side of the upper mold base 1, and a guide sleeve 14 is fixed in the hole groove 13. The setting of the guide rod 12 and the guide sleeve 14 is convenient for guiding the upper mold base 1 during assembly and installation, ensuring that the assembly work can be completed accurately and stably, and can effectively improve the accuracy and prevent deviation. The guide sleeve 14 is slidably sleeved on the outside of the guide rod 12. The template 5 has sufficient bearing capacity, rigidity and stability to form a good supporting force for the mold. A mounting hole 11 is provided on one side of the template 5. The template 5 is fixed to the bearing plate 4 through the mounting hole 11 by an inner hexagonal bolt. The template 5 is fixed to the bearing plate 4 by an inner hexagonal bolt, which can be suitable for narrow assembly occasions and is very convenient for assembly and maintenance. The template 5 is used to support the mold. An adjustment member 6 is provided on one side of the template 5 to match the upper mold base 1. The adjustment member 6 is used to adjust the distance between the upper mold base 1 and the template 5.

[0042] Among them, a positioning ring 15 is tightly sleeved on the outer surface of the guide rod 12, and the central axis of the positioning ring 15 is collinear with the central axis of the guide rod 12. The positioning ring 15 is made of soft material, which can prevent the upper mold base 1 and the template 5 from contacting and colliding with each other and causing damage when the upper mold base 1 is assembled and installed. It has a protective effect on the assembly and installation of the upper mold base 1 and the template 5. A positioning groove 16 connected to the hole groove 13 is provided on one side of the upper mold base 1. The positioning groove 16 is clamped with the positioning ring 15, and can achieve a pre-positioning effect when the upper mold base 1 is assembled.

[0043] In this solution, when the mold frame needs to be assembled, the assembly principle is as follows:

[0044] First, insert the bearing plate 4 onto the top surface of the spacer plate 3, and ensure that the mounting plate 17 is in close contact with the inner side of the spacer plate 3, and use the corresponding positioning pins to pass through the loading holes 18 to complete the installation of the bearing plate 4;

[0045] Next, place the template 5 flat on the top surface of the bearing plate 4 and use the hexagon socket bolts to pass through the mounting holes 11 to fix the template 5 on the bearing plate 4;

[0046] Then, take the upper mold base 1, and insert the upper mold base 1 downward after aligning the guide sleeve 14 and the guide rod 12 so that they are in the matching state. When the upper mold base 1 contacts the template 5, the positioning ring 15 engages with the positioning groove 16, and then the assembly of the upper mold base 1 and the template 5 is completed.

[0047] Further, such as Figure 1 、 Figure 4 and Figure 6 As shown, the adjusting member 6 includes: a mounting frame 61, the mounting frame 61 is fixed to one side of the template 5, an operating shaft 62 is rotatably connected to one side of the mounting frame 61, one end of the operating shaft 62 is rotated with one side of the template 5, and the angle between the operating shaft 62 and the template 5 is perpendicular to each other, and a transmission wheel 63 is fastened to the outer surface of the operating shaft 62, and the diameter of the transmission wheel 63 is greater than the diameter of the rotating wheel 64. The other end of the operating shaft 62 is fixed with a rotating wheel 64, and the central axis of the rotating wheel 64 is collinear with the central axis of the operating shaft 62.

[0048] The limiting rod 65 is slidably connected to one side of the mounting frame 61. When the spring 68 is not under stress, the limiting rod 65 can completely pass through the bearing plate a69. A connecting rod 66 is hinged between the limiting rod 65 and the transmission wheel 63. The length of the connecting rod 66 is less than the length of the limiting rod 65. A connecting ring 67 is sleeved on the outer surface of the limiting rod 65. A spring 68 is fixed between the connecting ring 67 and the mounting frame 61.

[0049] The supporting plate a69 is fixed on one side of the upper mold base 1. The supporting plate a69 is L-shaped, and the angle between the supporting plate and the upper mold base 1 is right-angled, which can ensure that the supporting plate a69 and the upper mold base 1 are in a relatively firm connection stability. A limiting hole 610 that is compatible with the limiting rod 65 is provided on one side of the supporting plate a69. There are multiple limiting holes 610 to meet the adjustment requirements at different heights.

[0050] It should be noted that an additional sleeve 7 is fixed on one side of the template 5, and a supporting plate b8 is fixed on one side of the upper mold base 1 of the additional sleeve 7. The supporting plate b8 and the supporting plate a69 have the same shape and size, and the angle between the supporting plate b8 and the upper mold base 1 is set at a right angle. The supporting plate b8 slides in the additional sleeve 7, and a sliding pin 9 is provided on one side of the additional sleeve 7. A hole 10 for the pin 9 to pass through is opened on one side of the supporting plate b8. By using the pin 9 to limit the supporting plate b8, the secondary limit is achieved after the height of the upper mold base 1 is adjusted, and the structure is simple and the design is reasonable.

[0051] Example 2: Please refer to Figure 2 、 Figure 3、 Figure 5 and Figure 7 This embodiment further explains the first embodiment, and the difference lies in that the lower die base 2 is optimized and a mounting component is added between the lower die base 2 and the spacer plate 3.

[0052] Specifically, a guide sleeve 19 is fixed to the top surface of the lower die base 2, and a guide column 20 is slidably connected inside the guide sleeve 19. The guide rod 12 and one end of the guide column 20 are both chamfered, and the length of the guide sleeve 14 is greater than the length of the guide rod 12. The inner diameter of the guide sleeve 19 is consistent with the outer diameter of the guide column 20, which can ensure that the lower die base 2 is in a relatively stable state when assembled. The other end of the guide column 20 is fixed to the bottom end of the load-bearing plate 4, and one end of the guide column 20 is chamfered to prevent jamming due to contact and engagement of the planes during assembly.

[0053] Among them, an additional plate 17 is fixed to the bottom end of the load-bearing plate 4. The shape of the additional plate 17 is the same as that of the partition plate 3. When the load-bearing plate 4 and the partition plate 3 are aligned and spliced, the additional plate 17 remains in a compact fit with the partition plate 3, and one side of the additional plate 17 abuts against the partition plate 3. The additional plate 17 is concave in shape, which not only plays a pre-positioning role, but also makes it convenient for subsequent staff to use bolts to pass through the mounting holes 11 to fix the load-bearing plate 4 and the partition plate 3, and loading holes 18 are provided between the additional plate 17 and the partition plate 3.

[0054] In this solution, when the height position of the upper die base 1 needs to be adjusted, the adjustment principle is as follows:

[0055] First, pull out the latch 9 to release the limiting state of the mounting sleeve 7 on the bearing plate b8;

[0056] Secondly, by rotating the rotating wheel 64, the operating shaft 62 rotates synchronously, driving the transmission wheel 63 to rotate synchronously. The transmission action of the connecting rod 66 causes the two limiting rods 65 to move towards each other under the force. At this time, the spring 68 is in a stretched state until the limiting rods 65 are completely separated from the limiting holes 610.

[0057] Then, the height position of the upper die base 1 is adjusted upward until the upper die base 1 is adjusted to a suitable height, and the rotating wheel 64 is released. The elastic action of the spring 68 causes the limiting rod 65 to rebound and reset, and then the limiting rod 65 automatically engages with the limiting hole 610, completing the limit of the upper die base 1.

[0058] Finally, the upper die base 1 is limited after height adjustment by inserting the pin 9 into the hole 10 .

[0059] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles.
