Description

Technical Field

[0001] This utility model relates to the field of die-casting mold technology, specifically to a die-casting mold for an automotive generator housing. Background Technology

[0002] In the die-casting production of automotive generator housings, the die-casting mold core needs to be replaced according to different housing specifications to adapt to diverse production requirements. In existing technologies, although the mold has a core replacement function, coolant channels are usually pre-set inside the mold core to guide coolant circulation and cooling through the built-in channels for heat dissipation.

[0003] This design with built-in channels has obvious flaws:

[0004] On the one hand, the channels need to be integrally machined with the mold core, which leads to a complex mold core structure and a significant increase in manufacturing costs;

[0005] On the other hand, the old mold cores that are replaced cannot be reused because their channels are compatible with the heat dissipation system of a specific mold, and can only be scrapped, which further increases the cost of production consumables.

[0006] Furthermore, in existing technologies, the locking of the mold core relies entirely on an independent mechanical structure and is unrelated to the heat dissipation system.

[0007] Typically, bolts, snap-fit ​​connections, or pin positioning are used to rigidly connect the mold core to the fixed and movable seats. These locking structures and the heat dissipation system are designed independently. The locking is only responsible for the mechanical fixation of the mold core, and the heat dissipation is only responsible for cooling. The two have no functional overlap. When replacing the mold core, the locking structure must be removed first, and then the heat dissipation pipes must be separated. The steps are fragmented and the operation is complicated. Utility Model Content

[0008] The purpose of this utility model is to provide a die-casting mold for an automotive generator housing in order to solve the above-mentioned problems, as detailed below.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] This utility model provides a die-casting mold for an automobile generator housing, including a guide mechanism, a fixed seat, and a movable seat. The fixed seat and the movable seat are respectively installed on the fixed part and the movable part of the guide mechanism, and a punch core and a die core are vertically inserted into the fixed seat and the movable seat, respectively.

[0011] Both the fixed seat and the movable seat are equipped with heat dissipation mechanisms to dissipate heat from the punch core and the die core, respectively.

[0012] The heat dissipation mechanism includes a cold zone liquid housing and a moving coolant housing and moving components. The punch core and the die core are each provided with a sealing groove on the side corresponding to the coolant housing for clearance fitting with the coolant housing.

[0013] Preferably, the fixed seat and the movable seat are provided with at least two mounting slots, and guide plates are fixedly connected to both sides of the punch core and the die core, and the guide plates are clearance-fitted with the mounting slots.

[0014] Preferably, the upper end of the mounting slot is configured as an outward flare.

[0015] Preferably, a sealing frame is fixedly connected to one side of the cold zone liquid housing corresponding to the sealing groove, and the sealing frame can fit into the punch core and the die core.

[0016] Preferably, both sides of the coolant housing are fixedly connected to a circulation pipe, which is a flexible hose.

[0017] Preferably, the movable component includes guide rods, the guide rods of the two movable components are slidably connected to the fixed seat and the movable seat respectively, and the two guide rods are fixedly connected to the two coolant housings respectively. The bolts of the two movable components are threadedly connected to the fixed seat and the movable seat respectively, and the two bolts are rotatably connected to the two coolant housings respectively.

[0018] Preferably, the length direction of the guide rod and bolt is consistent with the mold closing direction of the punch core and the die core.

[0019] Preferably, both the fixed seat and the movable seat have drainage holes at their bottoms.

[0020] Preferably, both the punch core and the die core are fixedly connected to at least two threaded heads, and the surface of the threaded heads is provided with threads.

[0021] The beneficial effects are:

[0022] 1. This application abandons the traditional design of built-in coolant channels in the mold core and adopts an external heat dissipation system. The mold core does not need to be machined as a whole, which simplifies the processing technology and significantly reduces the manufacturing cost. At the same time, the mold core is freed from the binding restriction of channels and specific heat dissipation systems. After replacement, it can be repeatedly adapted to different molds, avoiding the direct scrapping of old mold cores and reducing material waste.

[0023] 2. The mold core locking and heat dissipation system are integrated into a single operation, eliminating the need to separately remove the locking structure and separate the heat dissipation pipes. During replacement, simply moving the component to operate the coolant housing simultaneously unlocks the lock and separates the heat dissipation system. The same operation can be used to connect the locking and heat dissipation systems when installing a new mold core, simplifying the process and significantly reducing mold changeover time.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] See Figures 1-5 As shown, this utility model provides a die-casting mold for an automobile generator housing, including a guide mechanism 1, a fixed seat 2, and a movable seat 3. The fixed seat 2 and the movable seat 3 are respectively installed on the fixed part and the movable part of the guide mechanism 1. A punch core 4 and a die core 5 are vertically inserted into the fixed seat 2 and the movable seat 3, respectively.

[0034] Both the fixed base 2 and the movable base 3 are equipped with heat dissipation mechanisms 12, which dissipate heat from the punch core 4 and the die core 5, respectively.

[0035] The heat dissipation mechanism 12 includes a cold zone liquid housing 13 and a moving assembly 17 for moving the coolant housing 13. The punch core 4 and the die core 5 are each provided with a sealing groove 9 on the side corresponding to the coolant housing 13 for clearance fitting with the coolant housing 13.

[0036] In this application, the focus is on mold core replacement and how to solve the heat dissipation system layout problem during mold core replacement. The punch core 4 and the die core 5 are installed on the fixed seat 2 and the movable seat 3 in the form of plug-in connection. The fixed seat 2 and the movable seat 3 are installed on the guide mechanism 1. The guide mechanism 1 is the prior art. The guide mechanism 1 is used to guide the movement direction of the movable seat 3. The guide mechanism 1 also needs to be installed with a drive mechanism to move the movable seat 3. The entire guide mechanism 1 is installed on the frame. The frame is also provided with an injection mechanism. This is the prior art in this field and will not be described in detail here.

[0037] After the punch core 4 and the die core 5 are installed in place, the coolant housing 13 is moved by the moving component 17 and inserted into the sealing groove 9. In this process, the vertical positioning of the die core is completed by the cooperation between the coolant housing 13 and the sealing groove 9, and the connection between the die core and the heat dissipation system is also completed.

[0038] See Figure 1 , Figure 3 , Figure 4 as well as Figure 5 At least two mounting slots 10 are provided in the fixed seat 2 and the movable seat 3. Guide plates 8 are fixedly connected to both sides of the punch core 4 and the die core 5, and the guide plates 8 are clearance-fitted with the mounting slots 10. The upper end of the mounting slot 10 is set as an outward flare 11. At least two threaded heads 7 are fixedly connected to the top of the punch core 4 and the die core 5, and the surface of the threaded heads 7 is provided with threads.

[0039] In this embodiment, the mounting groove 10 and the guide plate 8 cooperate to ensure the stability of the punch core 4 and the die core 5 on the fixed seat 2 and the movable seat 3. The outer flare 11 facilitates the precise insertion of the guide plate 8 into the mounting groove 10, and the threaded head 7 facilitates the connection of the lifting device with the punch core 4 and the die core 5.

[0040] See Figure 4 and Figure 5 A sealing frame 14 is fixedly connected to one side of the coolant housing 13 corresponding to the sealing groove 9. The sealing frame 14 can fit against the punch core 4 and the die core 5. Circulation pipes 15, which are flexible hoses, are fixedly connected to both sides of the coolant housing 13.

[0041] In the prior art, water cooling is commonly used for mold cooling. This example mainly focuses on how the coolant and the mold core are combined. Other parts of the cooling system are not described here as prior art.

[0042] In this embodiment, coolant is stored in the coolant housing 13 and circulated in the coolant housing 13 through two circulation pipes 15. The coolant directly contacts one side of the mold core, which results in a large contact area and efficient heat dissipation. When the mold core needs to be replaced, the coolant in the coolant housing 13 needs to be released first.

[0043] See Figure 5 The movable assembly 17 includes guide rods 17a and 17b. Guide rods 17a are slidably connected to the fixed base 2 and the movable base 3, respectively, and are fixedly connected to the two coolant housings 13. Bolts 17b are threadedly connected to the fixed base 2 and the movable base 3, respectively, and are rotatably connected to the two coolant housings 13. The length direction of the guide rods 17a and bolts 17b is consistent with the mold closing direction of the punch core 4 and the die core 5. Drainage holes 16 are provided at the bottom of both the fixed base 2 and the movable base 3.

[0044] In this embodiment, both the fixed seat 2 and the movable seat 3 are provided with cavities for accommodating the punch core 4 and the die core 5. After the punch core 4 and the die core 5 are installed, their bottoms are in contact with the bottom of the cavity. At that time, only the top of the cavity is open. If the coolant inside the coolant housing 13 leaks, it will not be easy to detect. By opening the leakage hole 16, the coolant accumulation can be prevented.

[0045] Specifically, the principle of the moving component 17 in this embodiment is as follows:

[0046] The coolant housing 13 is guided in the direction of movement by the guide rod 17a, and the punch core 4 or the die core 5 can be moved by rotating the bolt 17b.

[0047] The working principle of this application is as follows:

[0048] S1. Connect the threaded head 7 at the top of the punch core 4 and the concave core 5 with the lifting tool, align the punch core 4 and the concave core 5 with the cavities of the fixed seat 2 and the movable seat 3 respectively, and use the guide plate 8 and the outer flare 11 at the upper end of the mounting groove 10 to achieve precise guidance, and vertically insert them to the bottom of the mold core and fit them against the bottom of the cavity to complete the initial placement of the mold core.

[0049] S2. Under the guidance of the guide rod 17a, the bolt 17b of the operating moving component 17 pushes the coolant housing 13 to translate towards the mold core, so that the sealing frame 14 on the coolant housing 13 tightly fits against the surfaces of the punch core 4 and the die core 5. At the same time, the coolant housing 13 is embedded in the sealing groove 9 on the side of the mold core. During this process, the clearance fit between the coolant housing 13 and the sealing groove 9 directly restricts the vertical displacement of the mold core, achieving mechanical locking; at the same time, the coolant housing 13 and the mold core form a heat dissipation contact, preparing for subsequent heat dissipation.

[0050] S3. Circulating coolant is introduced into the coolant housing 13 through the circulation pipe 15 hose. The coolant directly contacts the surfaces of the punch core 4 and the die core 5, and quickly removes the heat generated by die casting through heat conduction, ensuring the core temperature is stable and guaranteeing the die casting quality. The flexible design of the circulation pipe 15 does not affect the normal mold closing and opening actions.

[0051] S4. When the mold core needs to be replaced, first drain the coolant from the coolant housing 13 through the circulation pipe 15, then rotate the bolt 17b in the opposite direction to move the coolant housing 13 away from the mold core, causing it to disengage from the sealing groove 9, and simultaneously release the locking of the mold core; then, use a lifting tool to lift the threaded head 7 and vertically remove the punch core 4 and the die core 5 from the mounting groove 10 to complete the disassembly of the old mold core. When replacing the new mold core, simply repeat the above installation and docking steps.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
