Description

Technical Field

[0001] This application relates to the field of mold technology, and in particular to a mold tilting device. Background Technology

[0002] In injection molds, angled ejector structures are typically used to mold hooks, clips, or snaps that exist internally or externally on the product, where direct molding with a slider on the rear mold side is not possible. In common angled ejector structures, the ejector rod and guide rod are integrally molded, resulting in a thin and long ejector rod. This makes the ejector rod prone to jamming, breakage, or deformation during operation, reducing its service life. Therefore, a mold angled ejector device that prevents bending deformation is proposed. Utility Model Content

[0003] One of the objectives of this application is to provide a mold jacking device that can prevent bending deformation.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: a mold inclined ejector device, comprising a mold body, a front core block, a front core rod, and a support member. The mold body includes a front mold and a rear mold. The front core block is used to form the front plate of the glove box base. The front core block is slidably disposed on the rear mold and its moving direction is perpendicular to the front plate. The first end of the front core rod is used to form the second buckle of the front plate. The front core rod is slidably disposed inside the front core block near the first end and is inclined relative to the sliding direction of the front core block. The second end of the front core rod cooperates with the outer side of the rear mold through a guide structure. The support member is detachably installed on the top of the front core block and sleeved on the middle position of the front core rod. During mold opening, the front core block performs a demolding action and cooperates with the guide structure to drive the front core rod and the second buckle to demold synchronously.

[0005] Preferably, a mounting base is detachably mounted on the side of the rear mold, and a driving device is detachably mounted on the mounting base. The output end of the driving device is connected to the front core block, and the second end of the front core rod cooperates with the mounting base through the guide structure. During mold opening, the driving device is adapted to drive the front core block to perform a demolding action in a first direction, while the front core rod is adapted to move along a second direction under the action of the front core block and the guide structure until it separates from the second latch, wherein the first direction and the second direction are perpendicular to each other.

[0006] Preferably, the mounting base has a mounting groove at the top center, and the driving device is embedded in the mounting groove.

[0007] Preferably, the guiding structure includes a guide block and a guide groove disposed within the mounting base. The guide block is mounted on the second end of the front core rod. The guide groove is provided with a guide surface that mates with the guide block. The guide surface is parallel to the second direction. During mold opening, the guide block is adapted to engage with the guide surface under the drive of the front core rod, so that the guide block moves along the guide surface and drives the front core rod to separate from the second snap-fit.

[0008] Preferably, the guide structure further includes a clearance groove disposed within the mounting base and communicating with the guide groove. The clearance groove cooperates with the guide block and its length direction is parallel to the first direction. During mold opening, the guide block is adapted to move along the second direction until it corresponds to and cooperates with the clearance groove. Subsequently, the front core block and the front core rod are adapted to move synchronously along the first direction and away from the front plate under the cooperation of the guide block and the clearance groove.

[0009] Preferably, a mounting block is detachably mounted on the mounting base. The guide groove and the clearance groove are both disposed within the mounting block. One side of the mounting block is provided with a slot that communicates with both the guide groove and the clearance groove, and the clearance groove extends to the other side of the mounting block. The end of the guide block away from the front core rod extends to both sides to form a snap-fit ​​portion, and the guide block is detachably connected to the front core rod. When installing the guide block, the guide block is adapted to enter from the clearance groove until it engages with the slot, so that the snap-fit ​​portion engages with the guide groove or the clearance groove.

[0010] Preferably, the guiding structure includes a guide block and a guide groove 1 disposed in the mounting base. The guide block is installed at the second end of the front core rod and cooperates with the guide groove 1, and the length direction of the guide groove 1 is parallel to the second direction. During mold opening, the guide block is adapted to slide along the guide groove 1 under the drive of the front core rod.

[0011] Preferably, the guide structure further includes a second guide groove disposed within the mounting base and communicating with the first guide groove, the length direction of the second guide groove being parallel to the first direction; during mold opening, the guide block is adapted to move along the second direction until it corresponds to and engages with the second guide groove, and the front core block and the front core rod are adapted to move synchronously along the first direction and away from the front plate under the sliding engagement of the guide block and the second guide groove.

[0012] Preferably, the front core rod has multiple sets of second buckles corresponding to the forming front plate, and the front core rod cooperates with the driving device through multiple sets of corresponding guide structures; during mold opening, the front core rod is adapted to move synchronously along the second direction under the action of the front core block and the guide structure until it separates from the second buckles.

[0013] Preferably, the mold slanted ejector device further includes a front slanted ejector device and a rear slanted ejector device. The front slanted ejector device is installed in the front mold and is used to form the side groove of the glove box base side plate. The rear slanted ejector device is installed in the rear mold and is used to form the third buckle of the glove box base rear plate. The front slanted ejector device includes a mounting plate, a second slanted ejector rod, and a slanted guide post. The mounting plate is elastically and vertically slidably installed in the front mold. A second slider is slidably disposed in the mounting plate. A second movable block and a third movable block are rotatably installed in the second slider. The second slanted ejector rod is obliquely and slidably disposed in the front mold, with its first end used to form the side groove. The second end of the second slanted ejector rod is connected to the second movable block. The slanted guide post is installed in the front mold and forms an oblique sliding fit with the third movable block. When the mold is opened, the mounting plate and the second slanted ejector rod are adapted to remain stationary in the vertical direction under the action of elastic force. The slider is adapted to move horizontally under the action of the slanted guide post and the third movable block, thereby driving the second slanted ejector rod to move horizontally until it separates from the third buckle.

[0014] Compared with the prior art, the beneficial effects of this application are as follows:

[0015] (1) This utility model supports and limits the first end of the front core rod by placing it inside the front core block, supports and limits the middle part by a support member, and supports and limits the second end by a guide structure, thereby achieving support and limitation at both ends and the middle part of the front core rod, thereby further improving the stability and service life of the front core rod during the mold opening and closing process.

[0016] (2) This utility model combines the front core rod with the guide structure, so that the front core rod can be driven to demold simultaneously during the demolding process of the front core block, thereby realizing the synchronous demolding process of the two, that is, demolding without sequential action; it simplifies the mold structure, reduces production costs, and greatly shortens the time required for demolding, thereby improving production efficiency.

[0044] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0045] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0046] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0047] One preferred embodiment of this application, such as Figures 1 to 26 As shown, a mold slant ejector device includes a mold body 2, a front core block 7, a front core rod 8 (i.e., a slant ejector rod), and a demolding device 3. The mold body 2 includes a front mold 201 and a rear mold 202. The front core block 7 is used to form the outer side of the front plate 101 of the glove box base 1 and the first buckle 1011 on the front plate 101. The front core block 7 is slidably disposed on the rear mold 202 and its moving direction is perpendicular to the front plate 101. The first end (left end) of the front core rod 8 is used to form the second buckle 1012 of the front plate 101. The front core rod 8 is slidably disposed inside the front core block 7 and is inclined relative to the sliding direction of the front core block 7. The demolding device 3 is detachably installed on the side of the rear mold 202 and connected to the front core block 7. The second end of the front core rod 8 cooperates with the demolding device 3 through a guide structure 9.

[0048] It should be noted that the direction of movement of the front core block 7 for mold closing and demolding is set as the first direction, that is, the direction perpendicular to the front plate 101; the direction of movement of the front core rod 8 for mold closing and demolding is set as the second direction, that is, the direction parallel to the front plate 101; and the first direction and the second direction are perpendicular to each other.

[0049] It is understandable that during mold opening, the demolding device 3 will drive the front core block 7 to demold in the first direction. At the same time, the front core rod 8, driven by the front core block 7 and in conjunction with the guide structure 9, will move along the second direction until it separates from the second buckle 1012, thereby completing the demolding process of the two buckles in different directions. Furthermore, the demolding processes of the front core block 7 and the front core rod 8 are independent of each other, that is, the two will not interfere with each other.

[0050] It is worth mentioning that the reason for the relative tilting and sliding of the front core rod 8 and the front core block 7 is as follows: If the front core rod 8 and the front core block 7 were arranged parallel to each other, that is, the front core rod 8 is parallel to the first direction, then when the front core block 7 moves to demold, without considering the sliding resistance between the two, the movement of the front core block 7 would not be able to drive the front core rod 8 to move. However, because the two are tilted, when the front core block 7 moves, a component force acts on the front core rod 8, and with the help of the guide structure 9, it can drive the front core rod 8 to move to demold.

[0051] It should be understood that in traditional mold design, the driving of the front core rod 8 generally requires a driving source to be set in the front core block 7. When the mold is opened, the driving source will first drive the front core rod 8 to demold, and then the demolding device 3 will drive the front core block 7 to demold with the second buckle 1012. This method not only increases the complexity of the mold structure, but also requires additional space for the driving source to be arranged and maintained, which greatly increases the production cost. Furthermore, the step-by-step demolding of the two processes will greatly increase the demolding time and reduce work efficiency.

[0052] This application, through the cooperation of the relatively inclined front core rod 8 and the guide structure 9, achieves the demolding action of the front core rod 8 without the need for an additional drive source, simplifying the mold structure and reducing production costs; furthermore, the front core rod 8 and the front core block 7 demold simultaneously, greatly shortening the demolding time and improving production efficiency. Additionally, as... Figure 7 As shown, the demolding device 3 can be detachably installed on the side of the rear mold 202. This facilitates the installation, maintenance or replacement of the demolding device 3. On the other hand, the demolding device 3 is also independent of the mold body 2, meaning that there is no need to provide installation space for the demolding device 3 in the rear mold 202, making the structure more compact.

[0053] As a further description of the above embodiments: as Figure 7 and Figure 10As shown, the demolding device 3 includes a mounting base 301 and a driving device 302. The mounting base 301 can be detachably mounted to the side of the rear mold 202 by bolts. A mounting groove 3011 is provided at the top center of the mounting base 301. The driving device 302 can be detachably mounted in the mounting groove 3011 by bolts. The output end of the driving device 302 is detachably connected to the front core block 7. The front core rod 8 and the mounting base 301 cooperate through the guide structure 9.

[0054] It is understood that the drive device 302 is preferably a hydraulic cylinder, and the drive device 302 is embedded in the mounting groove 3011. After installation, the drive device 302 can abut against the mounting groove 3011, thereby improving the stability of the installation. In addition, during specific installation, the cylinder body of the hydraulic cylinder is relatively long. If the mounting base 301 has the same width as the cylinder body, it will increase the volume and weight of the mounting base 301. However, by adopting the above-mentioned installation method, the installation contact area between the hydraulic cylinder and the mounting base 301 can be greatly increased. This allows the width of the mounting base 301 to be designed to be shorter, while also ensuring the installation stability of the hydraulic cylinder. This reduces the weight of the mounting base 301 and the amount of material used, thereby reducing production costs. In addition, the mounting base 301 can also provide a certain degree of protection for the embedded hydraulic cylinder.

[0055] This application does not limit the specific structure of the guide structure 9, but two specific embodiments are provided below for reference:

[0056] Structure 1: such as Figure 12 As shown, the guide structure 9 includes a guide block 901 and a guide groove 902 disposed in the mounting base 301. The guide block 901 is installed at the second end (right end) of the front core rod 8. The guide groove 902 is provided with a guide surface 9021 that cooperates with the guide block 901. The guide surface 9021 is parallel to the second direction.

[0057] It is understandable that in the initial state (i.e., the mold-closed state): such as Figure 13 As shown, at this time, the guide block 901 and the guide surface 9021 on the right side of the guide groove 902 are in a mating state. During mold opening, as... Figure 14 As shown, the front core rod 8 is in a horizontal state at this time. The front core block 7 will move downward along the dotted line under the action of the hydraulic cylinder. Therefore, under the traction of the front core block 7, the guide block 901 at the right end of the front core rod 8 will move downward along the guide surface 9021, that is, move along the second direction until the front core rod 8 is separated from the second buckle 1012.

[0058] Further optimization, such as Figure 14 and Figure 15As shown, the guide structure 9 also includes a clearance groove 903 disposed in the mounting base 301 and communicating with the guide groove 902. The clearance groove 903 cooperates with the guide block 901 and its length direction is parallel to the first direction, that is, the clearance groove 903 is perpendicular to the guide groove 902.

[0059] Understandably, during mold opening, when the guide block 901 moves along the second direction and aligns with the clearance groove 903, the guide groove 902 loses its guiding and limiting function for the guide block 901. Subsequently, under the action of the front core rod 8 and the front core block 7, they move synchronously along the first direction and move away from the front plate 101. This is to ensure that after demolding, the front core rod 8 and the front core block 7 move further away from the front plate 101, facilitating subsequent part removal operations. It should be noted that after demolding along the second direction, the front core rod 8 is still in contact with the front plate 101. Therefore, when the molded glove box base 1 is ejected, the front core rod 8 can easily come into contact with the external clips or ribs of the glove box base 1, thus hindering the ejection of the product. Therefore, the clearance groove 903 is designed to further distance the front core rod 8 and the front core block 7 from the product, preventing the front core rod 8 from interfering with the product during subsequent ejection and demolding.

[0060] Further optimization, such as Figure 12 As shown, a mounting block 303 is detachably mounted on the mounting base 301, and both the guide groove 902 and the clearance groove 903 are provided in the mounting block 303; Figure 10 As shown, a slot 12 is provided on the left side of the mounting block 303, which is connected to both the guide groove 902 and the clearance groove 903. The clearance groove 903 extends to the right side of the mounting block 303. The end of the guide block 901 away from the front core rod 8 extends to both sides to form a snap-fit ​​part 9011, that is, the guide block 901 has a "T" shaped structure.

[0061] Understandably, when installing the guide structure 9, the mounting block 303 is first fixedly installed in the appropriate position of the mounting base 301 with bolts, thus determining the positions of the guide groove 902 and the clearance groove 903. Then, the guide block 901 is inserted into the clearance groove 903 on the right side, so that the guide block 901 cooperates with the slot 12. The locking part 9011 can prevent the guide block 901 from falling out of the slot 12, and the locking part 9011 cooperates with the guide groove 902 or the clearance groove 903 to achieve the function of guiding and limiting. Finally, the guide block 901 is fixedly connected to the corresponding front core rod 8 with bolts. It can be seen that the entire guide structure 9 is simple and convenient to install. Furthermore, the guide groove 902 and the clearance groove 903 are designed independently of the mounting base 301 by means of the mounting block 303. Therefore, if the guide groove 902 or the clearance groove 903 fails, it is not necessary to disassemble the entire mounting base 301. Only the mounting block 303 needs to be replaced, which greatly improves the convenience of maintenance and reduces maintenance costs.

[0062] Structure 2: such as Figure 16 As shown, a mounting block 303 is detachably mounted on the mounting base 301. The guide structure 9 includes a first guide groove 904 and a second guide groove 905 disposed on the mounting block 303 and connected to each other. The length direction of the first guide groove 904 is parallel to the second direction, and the length direction of the second guide groove 905 is parallel to the first direction. That is, the first guide groove 904 and the second guide groove 905 are perpendicular to each other. The guide block 901 forms a sliding fit with the first guide groove 904 and the second guide groove 905.

[0063] It is understandable that structure two is similar in principle to structure one above. That is, when the mold is opened, the guide block 901 will first slide along the guide groove 904 to achieve the demolding of the second buckle 1012. When the guide block 901 slides from the guide groove 904 to the guide groove 905, the front core rod 8 will move synchronously with the front core block 7 and move away from the front plate 101.

[0064] It should be noted that, with structure one, the guide block 901, guide groove 902, and clearance groove 903 adopt a non-connecting fit (i.e., a contact compression fit). Therefore, to ensure stability, corresponding grooves and holes need to be opened in the mounting block 303 during processing, increasing the number of processing steps, but facilitating disassembly and replacement during later maintenance. With structure two, the guide block 901 forms a sliding fit with guide groove one 904 and guide groove two 905, and the two guide grooves can be directly set on the outer side of the mounting block 303. This reduces the number of processing steps, and the guide grooves also serve as a guide and limiter for the guide block 901, reducing the friction force experienced by the guide block 901 during movement. Of course, both structures can meet practical needs, and those skilled in the art can choose according to the actual situation.

[0065] In this embodiment, as Figure 8 As shown, the rear end of the front core block 7 needs to be connected to the drive device 302, and the front end of the front core block 7 is formed by the front plate 101 of the glove box base 1. Therefore, a groove 11 can be hollowed out at the end of the front core block 7 near the drive device 302. In this way, the weight and material of the front core block 7 can be reduced while meeting the strength requirements.

[0066] Based on the above embodiments, the following problem exists: due to the design of the groove 11, the space for sleeve covering the sliding front core rod 8 is also limited, that is, the front core rod 8 located on the groove 11 is in a suspended state, which makes it easy to deform and bend, affecting its service life.

[0067] Therefore, in order to solve the above-mentioned technical problems, in this embodiment, as follows: Figure 9 and Figure 11 As shown, a support member 10 can be detachably installed on the top of the front core block 7 via bolts. The support member 10 is sleeved at the middle position of the outer side of the front core rod 8, thereby providing limiting support for the front core rod 8 and supporting it throughout the entire demolding process to prevent bending deformation and extend its service life. Specifically, the left end of the front core rod 8 is supported and limited by the front core block 7, the middle position is supported and limited by the support member 10, and the right end is supported and limited by the guide structure 9. This provides support and limitation at both ends and the middle position of the front core rod 8, thereby further improving the stability and service life of the front core rod 8 during mold opening and closing.

[0068] In this embodiment, as Figure 3 As shown, the front panel 101 has multiple second latches 1012, and the second latches 1012 have different orientations, so multiple sets of front core rods 8 can be used accordingly; specifically as follows... Figure 11 As shown, this application employs three sets of front core rods 8, which cooperate with the mounting base 301 through multiple sets of corresponding guide structures 9. During mold opening, the front core rods 8 can move synchronously along the second direction under the action of the front core block 7 and the guide structure 9 until they separate from the second snap fasteners 1012, thus realizing the synchronous demolding process of multiple second snap fasteners 1012.

[0069] In this embodiment, the mold slanted ejector device also includes a slanted core-pulling device 4, a front slanted ejector device 6, and a rear slanted ejector device 5.

[0070] Specifically, such as Figure 17 and Figure 18As shown, the inclined core-pulling device 4 includes a telescopic device 401 (e.g., a hydraulic cylinder or pneumatic cylinder), an inclined core rod 402, a connecting block 403, and an inclined guide groove 404. The inclined core rod 402 is obliquely slidably disposed within the front mold 201, with its first end used to form the inclined groove 1013 on the inner side of the front plate 101. The telescopic device 401 is detachably mounted to the side of the front mold 201 by bolts and is horizontally disposed. The connecting block 403 is mounted on the output end of the telescopic device 401. The inclined guide groove 404 is disposed on the side of the connecting block 403 and slides in cooperation with the second end of the inclined core rod 402. It can be understood that when the telescopic device 401 moves the connecting block 403, the inclined core rod 402 will slide obliquely along the inclined guide groove 404 under the traction of the inclined guide groove 404, thereby realizing the core-pulling and mold opening of the inclined core rod 402.

[0071] Therefore, by using the design of the connecting block 403 and the inclined guide groove 404, the inclined core rod 402 is indirectly driven by the telescopic device 401 for core pulling and demolding. This eliminates the need for the telescopic device 401 to be installed at an angle and directly connected to the inclined core rod 402. Figure 5 and Figure 6 As shown, the telescopic device 401 can be horizontally and detachably installed on the side of the front mold 201. In this way, the entire inclined core pulling device 4 is also designed to be installed independently of the front mold 201. That is, there is no need to provide more installation space for the inclined core pulling device 4 in the front mold 201. The structure is more compact and also facilitates later maintenance.

[0072] like Figures 19 to 22 As shown, the rear inclined ejector device 5 includes a second telescopic device 501 (e.g., a hydraulic cylinder or a pneumatic cylinder), an inclined ejector rod 502, and a push plate 503. The second telescopic device 501 is vertically mounted to the rear mold 202 by bolts. The push plate 503 is vertically slidably mounted to the rear mold 202 and connected to the output end of the second telescopic device 501. The first inclined ejector rod 502 is obliquely slidably mounted inside the rear mold 202. The top end of the first inclined ejector rod 502 is used to form the third latch 1021 of the rear plate 102 of the glove box base 1. The bottom end of the first inclined ejector rod 502 is movably connected to the push plate 503, as detailed below. Figure 22 As shown, a slider 13 is slidably installed inside the push plate 503, and a movable block 14 is rotatably installed inside the slider 13. The bottom end of the inclined push rod 502 is connected to the movable block 14.

[0073] It is understandable that during the ejection of product 1 (glove box base), if... Figure 20 and Figure 21As shown, the telescopic device 2 501 drives the push plate 503 to move upward. During the upward movement, the ejector pin will directly push the product out of the rear mold 202, and the inclined ejector rod 1 502 will also push the product out. However, the inclined ejector rod 1 502 will have a partial displacement in the horizontal direction during its inclined sliding, which will cause the inclined ejector rod 1 502 to gradually disengage from the third latch 1021 during the upward movement. At the same time, the movable block 14 will rotate in the slider 13, and the slider 13 itself will also move, thereby ensuring that the inclined ejector rod 1 502 can be smoothly separated from the third latch 1021.

[0074] like Figure 24 As shown, the front inclined ejector device 6 includes a mounting plate 601, an inclined ejector rod 602, and an inclined guide post 603. The mounting plate 601 is vertically slidably mounted in the front mold 201 via a (nitrogen) spring. The inclined ejector rod 602 is obliquely slidably mounted in the front mold 201. The bottom end of the inclined ejector rod 602 is used to form the side groove 1031 of the upper side plate 103 of the glove box base 1. The top end of the inclined ejector rod 602 is movably connected to the mounting plate 601 (its installation method is the same as that of the inclined ejector rod 502 mentioned above). That is, a slider 15 is slidably mounted in the mounting plate 601, and a movable block 16 and a movable block 17 are rotatably mounted in the slider 15. The top end of the inclined ejector rod 602 is connected to the movable block 16. The inclined guide post 603 is mounted in the front mold 201 and forms a sliding fit with the movable block 17.

[0075] It is understandable that, such as Figure 26 As shown, this is the mold-closed state, where the nitrogen spring is in a compressed, energy-storing state. During mold opening, the front mold 201 moves upward and separates from the rear mold 202. At this time, the nitrogen spring acts on the mounting plate 601 through its elastic force, and the mounting plate 601 acts on the second inclined ejector rod 602, keeping the second inclined ejector rod 602 and the mounting plate 601 stationary in the vertical direction. Simultaneously, the upward-moving inclined guide post 603 acts on the third movable block 17, causing the second slider 15 to move to the right. The second slider 15, through the second movable block 16, drives the second inclined ejector rod 602 to move horizontally to the right until it is demolded from the side groove 1031. The second inclined ejector rod 602 and the front mold 201 slide relative to each other at an angle. Finally, the second inclined ejector rod 602 moves upward synchronously under the action of the front mold 201 to open the mold. It can be seen that the front inclined ejector device 6 enables the side groove 1031 to be demolded by the mold opening and the elastic force of the nitrogen spring, without the need for an additional drive source, thereby reducing production costs.
