Description

Technical Field

[0001] This utility model relates to the field of die-casting mold technology, and more specifically to a horizontal oblique core-pulling mechanism that can pull cores synchronously at the same angle. Background Technology

[0002] The inclined core-pulling mechanism of die-casting molds is a specialized mechanism for solving the demolding problem of castings with inclined undercuts or complex concave structures. This mechanism typically consists of an inclined guide component, an inclined slider, and a core. The inclined slider connects to the core. Its core feature is that the movement trajectory of the inclined slider forms a stable angle with the mold opening direction. During the mold opening process, lateral parting is achieved through mechanical linkage or hydraulic drive, allowing the core to smoothly detach from the casting. The inclined core-pulling mechanism is widely used in the production of die-casting parts with complex geometric features, such as automotive parts and electronic device housings. It can ensure the integrity of product molding, improve mold life and production efficiency, and is an indispensable key technology in modern precision die casting.

[0003] Existing die-casting molds typically employ a single-core structure design for their inclined core-pulling mechanisms, meaning the inclined slider drives only one core movement. As illustrated in Chinese patent CN222628483U, entitled "A Large-Angle Inclined Core-Pulling Structure for a Mold," this design includes a guide rail, an inclined core-pulling seat, an inclined guide post, an inclined core-pulling body, and a clamping guide block. The inclined core-pulling seat is slidably connected within the guide rail, which is fixed within the stationary mold base. The inclined core-pulling seat can reciprocate along the guide rail, moving towards or away from the product's machining surface. An inclined guide hole is obliquely arranged in the center of the inclined core-pulling seat, and an inclined guide post is coaxially slidably arranged within the guide hole. The fixed end of the inclined guide post is fitted with a cap structure to limit and fix it to the moving mold base, while the free end of the inclined guide post can... The guide hole for inserting or exiting the inclined drawer is provided, and the lower end of the inclined guide post is inclined away from the machining surface. The end of the inclined drawer near the machining surface can slide out of the end of the guide rail. An inclined drawer surface is provided at the end of the inclined drawer near the product machining surface. The inclination direction of the inclined drawer surface is opposite to that of the inclined guide post. An inclined core-pulling body is guided and slidably connected to the inclined drawer surface. The inclined core-pulling body has a rectangular cube structure and can slide along the inclined drawer surface. The end of the inclined core-pulling body away from the inclined drawer is provided with a mold cavity groove that matches the shape of the product machining surface. A clamping guide block is slidably connected to one side of the inclined core-pulling body in the width direction. A mold cavity groove required for product machining is provided on one side of the clamping guide block in the width direction.

[0004] When a die-casting mold with the aforementioned inclined core-pulling mechanism opens, the inclined core-pulling seat first moves away from the product along the guide rail under the guidance of the inclined guide pillar, thereby driving the inclined core-pulling body to move. At the same time, the inclined core-pulling body is guided and restricted by the clamping guide block, thus moving obliquely, allowing the structure to automatically separate from the product and smoothly eject the product. However, this structure has the following technical defects. First, each core needs to be equipped with an independent inclined core-pulling mechanism, which complicates the mold structure and requires a large number of repetitive mechanisms when molding multi-feature castings. Second, the hydraulic cylinder of the inclined core-pulling mechanism generally maintains the same tilt angle as the core, which not only interferes with the mold opening and closing trajectory but also significantly increases the space occupied, weight, and manufacturing cost of the mold. In addition, when each independent core moves alternately in the cavity, there is a risk of motion interference due to timing control deviation, which forces a reduction in the mold opening speed and affects the molding quality of the casting. Utility Model Content

[0005] To address the above issues, and to overcome the problems of traditional die-casting molds where each core requires an independent inclined pulling mechanism, and the hydraulic cylinder and core must maintain the same tilt angle, leading to a complex mold structure and a significant increase in mold space, weight, and manufacturing costs, and where the alternating movement of each independent core within the cavity forces a reduction in mold opening speed, affecting casting quality, this invention aims to provide an inclined core-pulling mechanism that can simultaneously and at the same angle complete the core pulling and resetting of two cores, with the hydraulic cylinder positioned horizontally. This optimizes the mold structure, space occupancy, weight, and manufacturing costs, minimizes interference between cores, and ensures casting quality.

[0006] To achieve the above objectives, the technical solution of this utility model is:

[0007] A horizontal inclined core-pulling mechanism capable of synchronous and angled core pulling includes an inclined core-pulling base, a first inclined slider, a second inclined slider, a core, and a hydraulic cylinder. The inclined core-pulling base is connected to the output end of the hydraulic cylinder, and both the inclined core-pulling base and the hydraulic cylinder are horizontally positioned. The inclined core-pulling base has a first inclined guide block and a second inclined guide block arranged side by side with the same inclination. The first inclined slider has a first inclined guide groove that matches and slides with the first inclined guide block. The second inclined slider has a second inclined guide groove and a third inclined guide groove that match and slides with the first and second inclined guide blocks, respectively. The number of cores is two, and the two cores are respectively located on the first and second inclined sliders.

[0008] Preferably, it also includes a fixed seat, and the inclined drawer abuts against the fixed seat from front to back. The fixed seat has a first inclined slide and a second inclined slide that match the first inclined slider and the second inclined slider. The first inclined slide and the second inclined slide are closed by the inclined drawer and slide in sliding engagement with the first inclined slide and the second inclined slide respectively. The inclination direction of the first inclined slide and the second inclined slide is opposite to the inclination direction of the first inclined guide block and the second inclined guide block.

[0009] Preferably, the inclined draw seat has a cavity opposite to the fixed seat, and the first inclined guide block and the second inclined guide block are located in the cavity, with the fixed seat abutting against the cavity.

[0010] Preferably, the fixing seat is provided with first positioning holes in sequence, and the first positioning holes are used to fix the fixing seat to the mold frame by fasteners.

[0011] Preferably, the first and second inclined sliders are provided with a first mounting hole and a second mounting hole, respectively. The two cores are respectively inserted into the first and second mounting holes. A first step and a second step are formed in the first and second mounting holes, respectively. A third step is formed on the cores. The third steps of the two cores abut against the first and second steps, respectively.

[0012] Preferably, both cores are provided with positioning elements, which abut against the outer walls of the first and second inclined sliders, respectively.

[0013] Preferably, it also includes a pressure plate with a snap-fit ​​groove, which is used to fasten the pressure plate to the inclined drawer. The pressure plate also has a second positioning hole for fixing the pressure plate to the mold frame using fasteners.

[0014] Preferably, it also includes a pad block located at the bottom of the inclined drawer, and the pad block has a third positioning hole for fixing the pad block to the mold frame by means of fasteners.

[0015] Preferably, it also includes two stops, which are placed on the front and rear sides of the inclined draw seat and fixed to the hydraulic cylinder.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] The inclined core-pulling mechanism of this utility model allows the core connected to the first and second inclined sliders to perform core-pulling and resetting actions synchronously, thereby dispersing the core-pulling resistance during the core-pulling process. This avoids wear or jamming caused by overload when pulling a single core, and also avoids instantaneous stress fluctuations in the casting caused by the sequential pulling of different inclined core-pulling mechanisms, thus improving the yield of castings. At the same time, synchronous core-pulling will also reduce the number of inclined core-pulling mechanisms while ensuring demolding efficiency. The horizontally placed inclined core-pulling seat and hydraulic cylinder can directly convert horizontal movement into the inclined movement of the first and second inclined sliders, thereby avoiding the movement trajectory of the die-casting mold opening and closing, reducing the difficulty of mold opening and closing, and improving the space utilization rate in the vertical and horizontal directions. This will significantly optimize the space occupied by the mold, its weight, and its manufacturing cost. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the purpose of simplifying the description and do not indicate or imply that the orientation is a specific orientation or specific orientation structure and operation. Therefore, they should not be construed as limiting this utility model.

[0031] like Figures 1 to 5As shown, a horizontal inclined core-pulling mechanism capable of synchronous and angled core pulling includes an inclined core-pulling base 1, a first inclined slider 2, a second inclined slider 3, a core 4, and a hydraulic cylinder 5. The inclined core-pulling base 1 is connected to the output end of the hydraulic cylinder 5. The inclined core-pulling base 1 uses the hydraulic cylinder 5 as a power source and reciprocates under its drive. Both the inclined core-pulling base 1 and the hydraulic cylinder 5 are horizontally positioned. The inclined core-pulling base 1 has a first inclined guide block 101 and a second inclined guide block 102, which are arranged side-by-side and inclined relative to the horizontal direction. The inclinations of the first inclined guide block 101 and the second inclined guide block 102 are the same. A first inclined guide groove 201 is formed on the first inclined slider 2, which matches the first inclined guide block 101. That is, the first... The width and slope of the inclined guide groove 201 are adapted to the first inclined guide block 101, allowing the first inclined slider 2 to slide in contact with the first inclined guide block 101. The second inclined slider 3 has a second inclined guide groove 301 and a third inclined guide groove 302, which are respectively matched with the first inclined guide block 101 and the second inclined guide block 102. Specifically, the width and slope of the second inclined guide groove 301 are adapted to the first inclined guide block 101, and the width and slope of the third inclined guide groove 302 are adapted to the second inclined guide block 102. Furthermore, the slopes of the second inclined guide groove 301 and the third inclined guide groove 302 are the same. The second inclined slider 3 connects with the first inclined guide block 101 and the second inclined guide block 102 via the second inclined guide groove 301 and the third inclined guide groove 302, respectively. The guide block 102 slides, allowing the first inclined slider 2 and the second inclined slider 3 to move at the same angle and in the same direction. There are two cores 4, each corresponding to the first inclined slider 2 and the second inclined slider 3. The two cores 4 are driven by the lower slider and the second inclined slider 3 to perform core-pulling and resetting actions at the same angle and in the same direction. The inclined core-pulling mechanism of this invention uses a hydraulic cylinder 5 to drive the inclined core-pulling seat 1 to move horizontally reciprocally. The first inclined guide block 101 guides the first inclined slider 2 to move obliquely upwards or downwards. Simultaneously, the first inclined guide block 101, in conjunction with the second inclined guide block 102, guides the second inclined slider 3 to move obliquely upwards or downwards. At this time, the cores 4 connected to the first inclined slider 2 and the second inclined slider 3 will move synchronously. The synchronous core pulling and resetting action disperses the core pulling resistance during the core pulling process, avoiding wear or jamming caused by overload when pulling a single core 4. It also avoids instantaneous stress fluctuations in the casting caused by the sequential core pulling when different inclined core pulling mechanisms pull cores together, thereby improving the yield of castings. At the same time, synchronous core pulling will also reduce the number of inclined core pulling mechanisms while ensuring demolding efficiency. The horizontally placed inclined core pulling seat 1 and hydraulic cylinder 5 can directly convert horizontal movement into the inclined movement of the first inclined slider 2 and the second inclined slider 3, thereby avoiding the movement trajectory of the die-casting mold opening and closing, reducing the difficulty of mold opening and closing, and improving the space utilization in the vertical and horizontal directions. This will significantly optimize the space occupied by the mold, its weight, and manufacturing costs.

[0032] like Figures 1 to 3 as well as Figure 6As shown, it also includes a fixed base 6, with a slanted drawer 1 abutting against the fixed base 6. The fixed base 6 has a first slanted slide rail 601 and a second slanted slide rail 602 that match the first slanted slider 2 and the second slanted slider 3. It can be understood that the shape and slope of the first slanted slide rail 601 and the second slanted slide rail 602 are adapted to the first slanted slider 2 and the second slanted slider 3, respectively. The first slanted slide rail 601 and the second slanted slide rail 602 are closed by the slanted drawer 1. The first slanted slider 2 and the second slanted slider 3 slide in contact with the first slanted slide rail 601 and the second slanted slide rail 602, respectively. When the first slanted slider 2 and the second slanted slider 3 slide along the first slanted slide rail 601 and the second slanted slide rail 602, respectively... When the first inclined guide block 101 and the second inclined guide block 102 move, they can move synchronously within the closed first inclined slide 601 and the second inclined slide 602, respectively. The inclination direction of the first inclined slide 601 and the second inclined slide 602 is opposite to the inclination direction of the first inclined guide block 101 and the second inclined guide block 102. In this way, when the inclined drawer 1 moves horizontally, the height of the first inclined guide block 101 and the second inclined guide block 102 at the point of contact with the first inclined slider 2 and the second inclined slider 3 changes continuously, thereby smoothly guiding the first inclined slider 2 and the second inclined slider 3 to move synchronously within the first inclined slide 601 and the second inclined slide 602, respectively.

[0033] like Figure 1 , Figure 3 and Figure 5 As shown, it also includes a cavity 103 on the inclined drawer 1 that is opposite to the fixed seat 6. The first inclined guide block 101 and the second inclined guide block 102 are located in the cavity 103 and the fixed seat 6 abuts against the cavity 103. This can greatly reduce the overall volume formed after the inclined drawer 1 and the fixed seat 6 abut against each other. Correspondingly, only a smaller installation area needs to be processed on the mold frame, thereby avoiding space waste and making the overall structure of the die casting mold more compact and reasonable.

[0034] like Figure 1 and Figure 6 As shown, the fixed base 6 is provided with first positioning holes 603 in sequence. The first positioning holes 603 are used to fix the fixed base 6 to the mold frame by fasteners. The fasteners include positioning pins. There is no particular limitation on the number of first positioning holes 603. The first positioning holes 603 can also be screw holes, so that bolts can be threadedly connected and fixed to the mold frame. The setting of multiple first positioning holes 603 will form multiple positioning points between the connected positioning pins or bolts and the mold frame, ensuring a stable connection between the fixed base 6 and the mold frame.

[0035] like Figure 7 and Figure 8As shown, the first inclined slider 2 and the second inclined slider 3 are respectively provided with a first mounting hole 202 and a second mounting hole 303. The first mounting hole 202 and the second mounting hole 303 are both through holes, which pass through the upper and lower end faces of the first inclined slider 2 and the second inclined slider 3, respectively. The two cores 4 are respectively inserted into the first mounting hole 202 and the second mounting hole 303. The first mounting hole 202 and the second mounting hole 303 are respectively formed with a first step 202a and a second step 303a. That is to say, the first mounting hole 202 and the second mounting hole 303 each include two parts: a large inner diameter section and a small inner diameter section. A step is formed between the large inner diameter section and the small inner diameter section. A third step 401 is formed on the core 4. The third steps 401 of the two cores 4 abut against the first step 202a and the second step 303a, respectively, thereby restricting the cores 4 from sliding off under the action of gravity, so that the first inclined slider 2 and the second inclined slider 3 are stably connected to the cores 4.

[0036] like Figure 7 and Figure 8 As shown, each of the two cores 4 is provided with a positioning element 402. The positioning element 402 on the two cores 4 respectively forms a step position with the outer wall of the corresponding core 4. The step position abuts against the outer wall of the first inclined slider 2 and the second inclined slider 3. With the cooperation of the first step 202a, the second step 303a and the third step 401, the core 4 can be bidirectionally positioned, so that the two cores 4 can be stably maintained in cooperation with the first inclined slider 2 and the second inclined slider 3. In addition, it should be mentioned that the positioning element 402 and the corresponding core 4 can be detached by means of threaded connection, so that the positioning element 402 can be removed. In this way, the positioning on one side will be released, and the core 4 can be removed from the corresponding first mounting hole 202 and second mounting hole 303 for replacement. By replacing different cores 4, the inclined core pulling mechanism of this utility model can cover a variety of different castings, significantly reducing the development cost of die casting molds.

[0037] like Figures 1 to 3 as well as Figure 9 As shown, it also includes a pressure plate 7, which has a fastening groove 701. The pressure plate 7 is fastened to the inclined drawer 1 through the fastening groove 701. The inclined drawer 1 is restricted to the mold frame by the pressure plate 7, thereby maintaining the connection with the mold frame. The pressure plate 7 has a second positioning hole 702. There is no particular limitation on the number of second positioning holes 702. The positioning pin can be fixed to the mold frame of the die-casting mold through the second positioning hole 702. The second positioning hole 702 can also be a screw hole, thereby allowing the bolt to be threadedly connected and fixed to the mold frame. The setting of multiple second positioning holes 702 will form multiple positioning points between the connected positioning pin or bolt and the mold frame, ensuring a stable connection between the pressure plate 7 and the mold frame.

[0038] like Figure 2As shown, it also includes a pad 8, which is located at the bottom of the inclined drawer 1. The pad 8 can prevent the inclined drawer 1 from directly contacting the mold frame, thereby reducing the frictional damage to the mold frame when the inclined drawer 1 moves, thus protecting the mold frame. There is no particular limitation on the number of third positioning holes 801. The positioning pin can be fixed to the mold frame of the die-casting mold through the third positioning hole 801. The third positioning hole 801 can also be a screw hole, thereby allowing the bolt to be threadedly connected and fixed to the mold frame. The setting of multiple third positioning holes 801 will form multiple positioning points between the connected positioning pin or bolt and the mold frame, ensuring a stable connection between the pad 8 and the mold frame.

[0039] like Figures 1 to 3 As shown, it also includes two stop blocks 9. The two stop blocks 9 are placed on the front and rear sides of the inclined drawing seat 1 and fixed to the oil cylinder 5. When the piston rod of the oil cylinder 5 drives the inclined drawing seat 1 to move, the two stop blocks 9 can keep the inclined drawing seat 1 moving in a straight line, avoid deviating from the preset path, and ensure the smooth core pulling and resetting of the core 4.

[0040] Combination Figures 1 to 9 The inclined pulling mechanism of this utility model requires first inserting a positioning pin or bolt through the first positioning hole 603 of the fixed seat 6 to fix the fixed seat 6 to the mold frame. Then, the positioning pin or bolt is inserted through the second positioning hole 702 and the third positioning hole 801 of the pressure plate 7 and the pad 8 in sequence to fix the pressure plate 7 and the pad 8 to the mold frame. When the die-casting mold is opened and closed, the hydraulic cylinder 5 is operated. The output end of the hydraulic cylinder 5 will drive the inclined pulling seat 1 to move horizontally. The first guide part and the second guide part of the inclined pulling seat 1 guide the first inclined slider 2 and the second inclined slider 3 to move obliquely at the same angle in the first inclined slide 601 and the second inclined slide 602 of the fixed seat 6. At this time, the core 4 connected to the first inclined slider 2 and the second inclined slider 3 will perform core pulling and resetting actions synchronously.

[0041] The embodiments and descriptions above are merely illustrative of the principles and preferred embodiments of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
