Abstract
Description
Technical Field
[0001] This disclosure relates to the technical field of die casting molds, and in particular to an interlocking mold foot structure and an aluminum alloy die casting mold. Background Technology
[0002] In aluminum alloy die-casting molds, the mold feet (also known as "support feet") perform two core functions:
[0003] Mold installation and positioning: Serves as a fixed support base for the mold and the die-casting machine template, ensuring mold closing accuracy;
[0004] Ejector system limit: By controlling the return position of the front pin plate (ejector fixing plate) and the bottom pin plate (ejector push plate) through height control, excessive impact on the mold during reset is prevented.
[0005] Existing mold foot structures such as Figure 1 As shown, the mold base body 11 and the moving mold blank 12 are fixed together by mold foot bolts 13, which in turn fix the bottom pin plate / face pin plate. However, during maintenance, the mold foot bolts need to be removed to remove the mold base body in order to take out the bottom pin plate 14 / face pin plate 15. Moreover, the operation involves heavy lifting tools, which is time-consuming. Repeated disassembly and assembly can easily lead to wear of the mold foot bolt threads and a decrease in the accuracy of the mounting surface, which will affect the stability of the mold in the long term. In the high-temperature die casting environment, aluminum alloy chips can easily penetrate into the mating surface, which will increase the difficulty of disassembly and reduce maintenance efficiency. Utility Model Content
[0006] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a modular mold foot structure and an aluminum alloy die-casting mold that are easier to disassemble and more efficient to maintain.
[0007] The purpose of this disclosure is achieved through the following technical solution:
[0008] A modular mold base structure includes a moving mold blank, a support base, and a pin plate assembly. The moving mold blank is connected to the support base, the support base has an installation area, and the pin plate assembly is located in the installation area.
[0009] The inlaid mold foot structure further includes a limiting component, which includes a limiting block and a spiral bolt. One side of the limiting block is connected to the pin plate assembly. The support base has a limiting groove. The limiting block is located in the mounting area. The limiting block has a first spiral hole. The support base has a second spiral hole. The second spiral hole communicates with the limiting groove. The screw portion of the spiral bolt passes through the first spiral hole and the second spiral hole in sequence. The top of the spiral bolt abuts against the limiting block, so that one side of the limiting block also abuts against the support base. One end of the pin plate assembly abuts against the moving mold blank.
[0010] In one embodiment, the support base includes a first support and a second support, both of which are connected to the moving mold blank. The first support and the second support together form the mounting area. Both the first support and the second support are provided with the second spiral hole and the limiting groove.
[0011] In one embodiment, the support has a limiting channel, and the needle plate assembly has a limiting protrusion located within the limiting channel.
[0012] In one embodiment, the first support and the second support are arranged opposite to each other.
[0013] In one embodiment, the needle plate assembly includes a bottom needle plate, a front needle plate, and needle plate supports. The front needle plate is detachably mounted on the bottom needle plate, the needle plate supports are connected to the front needle plate, and one end of the needle plate supports abuts against the moving mold blank. One side of the limiting block is connected to the bottom needle plate.
[0014] In one embodiment, the number of needle plate legs is multiple.
[0015] In one embodiment, the needle plate support includes a mounting top and an abutting support connected to each other. The face needle plate has an anti-slip groove and an abutting channel. The bottom of the anti-slip groove communicates with the abutting channel. The mounting top is located in the anti-slip groove and abuts against the bottom needle plate. The abutting support passes through the abutting channel, and one end of the abutting support abuts against the moving mold blank.
[0016] In one embodiment, the opening of the anti-displacement groove faces the bottom pin plate.
[0017] In one embodiment, the moving mold blank has a fixing groove, and part of the structure of the needle plate support is located in the fixing groove.
[0018] An aluminum alloy die-casting mold includes the inlaid mold foot structure described in any of the above embodiments.
[0019] Compared with the prior art, this disclosure has at least the following advantages:
[0020] Because the interlocking mold base structure uses limiting blocks and screw bolts, and the limiting blocks are connected to the needle plate assembly, after the needle plate assembly is installed using the limiting blocks and screw bolts, the limiting blocks abut against the support base to fix the needle plate assembly. When maintenance is required, the needle plate assembly can be removed simply by loosening and removing the screw bolts. The support base does not need to be removed during the entire maintenance period, thereby avoiding wear on the reference surface between the support base and the moving mold blank, and also reducing the use of heavy lifting tools, thus avoiding the risks associated with heavy lifting tools. This reduces the difficulty of maintaining the needle plate assembly and improves maintenance efficiency. Attached Figure Description

Detailed Implementation
[0030] To facilitate understanding of this disclosure, a more complete description will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the present disclosure. However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.
[0031] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0033] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:
[0034] Please see Figure 2 The inlaid mold foot structure 10 of this utility model includes a movable mold blank 100, a support base 200 and a needle plate assembly 300. The movable mold blank 100 is connected to the support base 200. The support base 200 has an installation area 201 and the needle plate assembly 300 is located in the installation area 201.
[0035] Combination Figures 3 to 5As shown, the interlocking mold base structure 10 also includes a limiting component 400, which includes a limiting block 410 and a spiral bolt 420. One side of the limiting block 410 is connected to the needle plate assembly 300. The support base 200 has a limiting groove 202. The limiting block 410 is located in the mounting area 201. The limiting block 410 has a first spiral hole 411. The support base 200 has a second spiral hole 203. The second spiral hole 203 communicates with the limiting groove 202. The screw of the spiral bolt 420 passes through the first spiral hole 411 and the second spiral hole 203 in sequence, and the top of the spiral bolt 420 abuts against the limiting block 410, so that one side of the limiting block 410 also abuts against the support base 200. One end of the needle plate assembly 300 abuts against the moving mold blank 100. Therefore, when maintaining or replacing the needle plate assembly 300, it is only necessary to loosen and remove the spiral bolt 420 without removing the support base 200.
[0036] Furthermore, one side of the limiting block 410 is connected to the needle plate assembly 300, and this connection can be a fixed connection or a detachable connection.
[0037] In the above embodiments, since the interlocking mold foot structure 10 adopts a limiting block 410 and a spiral bolt 420, and the limiting block 410 is connected to the needle plate assembly 300, after the needle plate assembly 300 is installed by the limiting block 410 and the spiral bolt 420, the limiting block 410 abuts against the needle plate assembly 300 and the support seat 200 respectively to fix the needle plate assembly 300. When maintenance is required, the needle plate assembly 300 can be removed by simply loosening and removing the spiral bolt 420. The support seat 200 does not need to be removed during the entire maintenance period, thereby avoiding wear on the reference surface between the support seat 200 and the moving mold blank 100, and also reducing the use of heavy lifting tools, thereby avoiding the risks of heavy lifting tools. This reduces the difficulty of maintaining the needle plate assembly 300 and improves maintenance efficiency.
[0038] Furthermore, such as Figures 2 to 4 As shown, the support base 200 includes a first support 210 and a second support 220. Both the first support 210 and the second support 220 are connected to the moving mold blank 100. The first support 210 and the second support 220 together form an installation area 201. Both the first support 210 and the second support 220 are provided with a second spiral hole 203 and a limiting groove 202. It can be understood that there are multiple and equal numbers of spiral bolts 420, limiting grooves 202 and limiting blocks 410. Thus, each limiting block 410 is located in the corresponding limiting groove 202. A portion of the spiral bolts 420 abut against the first support 210, and the remaining portion abut against the second support 220. This allows multiple limiting blocks 410 to jointly support both sides of the needle plate assembly 300 to prevent the needle plate assembly 300 from shifting after installation, ensuring the stability of the aluminum alloy die-casting mold during operation.
[0039] Furthermore, such as Figure 2 and Figure 4 As shown, a support 210 has a limiting channel 211, and the needle plate assembly 300 has a limiting protrusion 301. The limiting protrusion 301 is located in the limiting channel 211. Through the cooperation between the limiting protrusion 301 and the limiting channel 211, and with the support of the limiting block 410, the offset of the needle plate assembly 300 after installation can be further limited, thereby further ensuring the stability of the aluminum alloy die-casting mold.
[0040] In another embodiment, one support 210 and two supports 220 are arranged opposite to each other.
[0041] In one embodiment, such as Figure 2 , Figure 5 and Figure 6 As shown, the needle plate assembly 300 includes a bottom needle plate 310, a front needle plate 320, and a needle plate support 330. The front needle plate 320 is detachably installed on the bottom needle plate 310, the needle plate support 330 is connected to the front needle plate 320, and one end of the needle plate support 330 abuts against the moving mold blank 100. One side of the limiting block 410 is connected to the bottom needle plate 310. It is understood that when installing the needle plate assembly 300, the needle plate support 330 abuts against the moving mold blank 100, and then the limiting block 410 is moved into the limiting groove 202. Then, the limiting block 410 is fixed by the screw bolt 420, so that the limiting block 410 abuts against the support base 200 by the screw bolt 420. With the needle plate support 330 abutting against the moving mold blank 100, the entire needle plate assembly 300 can be fixed to prevent displacement. In addition, since the face needle plate 320 can be detachably installed on the bottom needle plate 310, when only the face needle plate 320 or the bottom needle plate 310 needs to be replaced, the needle plate assembly 300 can be removed by loosening the screw bolt 420 and removing it. Specifically, a new face needle plate 320 or bottom needle plate 310 can be replaced and then reinstalled. This reduces the maintenance difficulty of the face needle plate 320 and the bottom needle plate 310. In this embodiment, there are multiple needle plate support 330s.
[0042] Furthermore, combined Figure 7As shown, the needle plate support 330 includes a mounting top 331 and an abutting support 332 connected to each other. The face needle plate 320 has an anti-slip groove 321 and an abutting channel 322. The bottom of the anti-slip groove 321 communicates with the abutting channel 322. The mounting top 331 is located in the anti-slip groove 321 and also abuts against the bottom needle plate 310. The abutting support 332 passes through the abutting channel 322, and one end of the abutting support 332 abuts against the moving mold blank 100. Specifically, the end of the abutting support 332 away from the face needle plate 320 abuts against the moving mold blank 100. Because the needle plate support 330 has a mounting top 331 and an abutment support 332, and the face needle plate 320 has an anti-slip groove 321 and an abutment channel 322, the mounting top 331 is located in the anti-slip groove 321 and abuts against the bottom needle plate 310. Therefore, the needle plate support 330 itself is restricted from moving. Consequently, after the needle plate assembly 300 is installed, the needle plate support 330 is not easily moved, ensuring the stability of the aluminum alloy die-casting mold during operation. In this embodiment, the opening of the anti-slip groove 321 faces the bottom needle plate 310.
[0043] In another embodiment, such as Figure 5 As shown, the limiting protrusion 301 is provided on the bottom needle plate 310 and the top needle plate 320, and the limiting protrusion 301 of the bottom needle plate 310 and the limiting protrusion 301 of the top needle plate 320 are arranged in the same vertical direction.
[0044] like Figure 6 As shown, in one embodiment, the moving mold blank 100 has a fixing groove 101, and part of the structure of the needle plate support 330 is located in the fixing groove 101. In this way, when the entire needle plate assembly 300 is installed, since part of the structure of the needle plate support 330 is located in the fixing groove 101, and the needle plate support 330 is connected to the face needle plate 320, it is further ensured that the needle plate assembly 300 will not shift as a whole, thus ensuring the stability of the subsequent die casting mold during operation.
[0045] In this embodiment, part of the structure of the abutment support 332 of the needle plate support 330 is located in the fixing groove 101.
[0046] This disclosure also provides an aluminum alloy die-casting mold, including the inlaid mold foot structure 10 of any of the above embodiments.
[0047] Compared with the prior art, this disclosure has at least the following advantages:
[0048] Since the interlocking mold base structure 10 uses a limiting block 410 and a screw bolt 420, and the limiting block 410 is connected to the needle plate assembly 300, after the needle plate assembly 300 is installed by the limiting block 410 and the screw bolt 420, the limiting block 410 abuts against the needle plate assembly 300 and the support seat 200 respectively to fix the needle plate assembly 300. When maintenance is required, the needle plate assembly 300 can be removed simply by loosening and removing the screw bolt 420. The support seat 200 does not need to be removed during the entire maintenance period, thereby avoiding wear on the reference surface between the support seat 200 and the moving mold blank 100, and also reducing the use of heavy lifting tools, thereby avoiding the risks of heavy lifting tools. This reduces the difficulty of maintaining the needle plate assembly 300 and improves maintenance efficiency.
[0049] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
