Description

Technical Field

[0001] This invention relates to the field of injection molds, and more particularly to an injection mold capable of detecting the position and orientation of injection-molded semi-finished products and its working method. Background Technology

[0002] The secondary injection molding process refers to injecting plastic raw materials into a primary injection mold to make a semi-finished product, and then placing the semi-finished product into the lower mold of a secondary injection mold and injecting the same or different plastic materials again to make the finished product.

[0003] In other words, the product is made by wrapping a semi-finished product in plastic material. Therefore, the way the semi-finished product is placed in the lower mold is crucial to the shape of the finished product.

[0004] Because the semi-finished product needs to be injected into the secondary injection mold, the mold, after encasing the semi-finished product, occupies the position of the sensor used to install and detect whether the semi-finished product is placed correctly. As a result, during the secondary injection, the semi-finished product can only be judged manually to determine whether it is placed backwards.

[0005] For irregularly shaped semi-finished products, workers can easily determine the correct orientation based on the shape. However, for regular semi-finished products, such as axially symmetrical semi-finished products, workers may mistake the front and back during placement, causing the semi-finished product to be injection molded in the wrong orientation when placed in the lower mold, making the final product unusable. Summary of the Invention

[0006] One advantage of this invention is that it provides an injection mold and its working method that can detect the position of the injection-molded semi-finished product, which can detect the placement posture of the semi-finished product placed in the lower mold to ensure that a qualified product is finally injection-molded.

[0007] Another advantage of the present invention is that it provides an injection mold and its working method that can detect the position of the injection-molded semi-finished product, which can detect the placement position of the semi-finished product placed in the lower mold to ensure that the thickness of the bottom and top of the final injection-molded product meets the actual requirements.

[0008] Another advantage of this invention is that it provides an injection mold that can detect the position of the injection-molded semi-finished product and its working method. The positioning rod set in this invention can be left unreset after injection molding to avoid the positioning rod resetting and sticking to the product.

[0009] Another advantage of the present invention is that it provides an injection mold that can detect the position of the injection-molded semi-finished product and its working method, which enables the positioning rod to be automatically removed from the semi-finished product when the upper mold is closed, so as to produce a product with no bottom depression.

[0010] To achieve at least one of the above advantages of the present invention, the present invention provides an injection mold capable of detecting the position of a semi-finished product for injection molding at least half of the finished product, wherein a positioning notch is formed at a predetermined position on the lower periphery of the semi-finished product, and the injection mold capable of detecting the position of the semi-finished product includes:

[0011] A mold body includes an upper mold and a lower mold. The upper mold is closable and disposed above the lower mold. The lower mold includes a lower mold body and a mounting platform. The top wall of the lower mold body is recessed downward to form a placement space for placing the semi-finished product. The lower mold body forms a movable space. The mounting platform is movably mounted in the movable space along the opening and closing direction of the upper mold. The lower mold body forms an insertion channel along the opening and closing direction of the upper mold, connecting the placement space and the movable space.

[0014] According to one embodiment of the present invention, the conveyor assembly includes at least one elastic element and a reset rod. The elastic element is telescopically mounted between the lower mold body and the mounting platform. When the mounting platform drives the positioning rod to move along the mold closing direction of the upper mold, the elastic element undergoes elastic deformation and tends to drive the mounting platform to move along the mold opening direction of the upper mold. The lower mold body forms a moving channel. The reset rod passes through the moving channel and extends partially out of the top wall of the lower mold body. The bottom of the reset rod is connected to the mounting platform.

The lower mold forms a mounting groove. Each set of fixing components includes a telescopic member and a fixing structure. The telescopic member is movably mounted in the mounting groove in a transverse direction perpendicular to the mold closing direction of the upper mold. The fixing structure includes a locking block and a locking groove. The locking block is disposed at the end of the telescopic member and partially extends out of the mounting groove. The locking block extending out of the mounting groove can be squeezed when the mounting platform moves in the mold opening and closing direction, causing the telescopic member to undergo elastic deformation. The locking block can engage with the locking groove when the reset rod is squeezed by the upper mold and the mounting platform moves in the mold closing direction of the upper mold until the positioning rod is withdrawn from the placement space. The conveyor assembly includes a pusher. The pusher is connected to the lower mold body to push the mounting platform to move in the mold opening direction of the upper mold.

[0016] According to one embodiment of the present invention, the mounting groove is formed on the lower mold body, and the slot is formed on the side of the mounting platform facing the fixed body.

[0017] According to one embodiment of the present invention, the injection mold capable of detecting the position of the injection-molded semi-finished product further includes a limiting structure, the limiting structure including a limiting member and a limiting channel, wherein the limiting member is movably installed in the limiting channel, either the limiting member or the limiting channel is disposed on the lower mold body, and the other is disposed on the mounting platform.

[0018] According to one embodiment of the present invention, the limiting channel is formed on the mounting platform, the limiting member is mounted on the lower mold body, and the elastic member is sleeved on the portion of the limiting member that extends out of the limiting channel.

[0019] According to one embodiment of the present invention, the bottom wall of the active space is recessed downward to form a limiting groove, and the elastic element is retractably installed in the limiting groove.

[0020] According to one embodiment of the present invention, the bottom wall of the lower mold body forming the placement space protrudes upward to form a molding protrusion, the molding protrusion allowing the semi-finished product to form an axially inserted slot. The injection mold capable of detecting the position of the injection-molded semi-finished product further includes an installation position detection component, the installation position detection component comprising:

[0021] A movable component is provided, wherein the lower mold forms an active channel and an outlet communicating with the active channel, the movable component is movably inserted into the active channel, and a portion of the movable component penetrates the bottom wall of the placement space to extend into the placement space, the portion of the movable component extending into the placement space can be moved as a whole by the squeezing action of the semi-finished product, and then the end of the movable component away from the placement space can move through the outlet in the direction of extending out of the active channel;

[0022] A reset component is connected to the movable component, and the reset component is capable of elastic deformation and tending to return to its original position when the movable component is moved by the pressure of the semi-finished product.

[0023] A triggered component, the triggered component including a triggered element, the end of the movable element away from the placement space being disposed opposite to the triggered element, the triggered element being communicatively connected to a controller that controls the mold to perform operations, and the movable element being able to move closer to or away from the triggered element.

[0024] According to one embodiment of the present invention, the triggered component further includes an insulating housing, the triggered member is mounted on the insulating housing, the insulating housing is used to protect the triggered member, the insulating housing forms a communicating space, and one end of the movable member away from the placement space is movably inserted into the communicating space through the outlet.

[0025] To achieve at least one of the advantages of this invention, the present invention provides a method for operating an injection mold capable of detecting the position and orientation of a semi-finished injection molded product, comprising the following steps:

[0026] Half of the finished product is placed in a placement space formed by a lower mold, such that a portion of a positioning rod extending into the placement space is inserted into a positioning notch formed by the half-finished product.

[0027] An upper mold is fitted onto the lower mold to form the product by injection molding;

[0037] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0038] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention 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. Therefore, the above terms should not be construed as limiting this invention.

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

[0040] refer to Figure 1 An injection mold capable of detecting the position of a semi-finished product according to a preferred embodiment of the present invention will be described in detail below. This injection mold is used to injection mold at least half of a finished product 900. A positioning notch 90001 is formed at a predetermined position on the lower periphery of the semi-finished product 900.

[0041] In one embodiment, the semi-finished product 900 is a winding frame for a coil assembly.

[0042] refer to Figures 2 to 3 Specifically, the injection mold capable of detecting the position of the injection-molded semi-finished product includes a mold body 10, a positioning rod 20, and a moving assembly 30.

[0043] The mold body 10 includes an upper mold 11 and a lower mold 12. The upper mold 11 is closably disposed above the lower mold 12.

[0044] refer to Figure 3 and Figure 7 The lower mold 12 includes a lower mold body 121 and a mounting platform 122. The top wall of the lower mold body 121 is recessed downward to form a placement space 12101 for placing the semi-finished product 900. The lower mold body 121 also forms a movable space 12102, and the mounting platform 122 is movably mounted in the movable space 12102 along the opening and closing direction of the upper mold 11.

[0045] refer to Figure 7 The lower mold body 121 forms an insertion channel 12103 along the opening and closing direction of the upper mold 11, connecting the placement space 12101 and the movable space 12102. The positioning rod 20 is connected to the mounting platform 122 in such a way that it passes through the insertion channel 12103 and partially extends into the placement space 12101. The positioning rod 20 can be inserted into the positioning notch 90001 when the semi-finished product 900 is placed in the placement space 12101 in the correct posture. In other words, the operator judges whether the placement posture of the semi-finished product 900 is correct by whether the positioning notch 90001 formed by the semi-finished product 900 in the placement space 12101 is inserted into the positioning rod 20 extending into the placement space 12101.

[0046] It is understood that when the positioning notch 90001 formed by the semi-finished product 900 is successfully assembled with the positioning rod 20 extending into the placement space 12101, the placement posture of the semi-finished product 900 in the placement space 12101 is correct; when the positioning notch 90001 formed by the semi-finished product 900 cannot be assembled with the positioning rod 20 extending into the placement space 12101, the semi-finished product 900 cannot be placed in the placement space 12101, and thus it can be determined that the placement posture of the semi-finished product 900 is incorrect.

[0047] The conveyor assembly 30 is installed on the lower mold 12 in a manner that enables the positioning rod 20 to move along the opening and closing direction of the upper mold 11.

[0048] In one embodiment, the conveyor belt assembly 30 is connected to the lower mold body 121 to drive the mounting platform 122 to move along the opening and closing direction of the upper mold 11. Thus, when the conveyor belt assembly 30 pushes the mounting platform 122 to move along the opening direction of the upper mold 11, the mounting platform 122 drives the positioning rod 20 to extend into the placement space 12101 along the insertion channel 12103, so that the positioning rod 20 can detect the placement posture of the semi-finished product 900; when the conveyor belt assembly 30 drives the mounting platform 122 to move along the closing direction of the upper mold 11, the mounting platform 122 drives the positioning rod 20 to be withdrawn from the placement space 12101 along the insertion channel 12103, so that the positioning rod 20 is separated from the semi-finished product 900, so that the product can be subsequently injection molded.

[0049] In one example, the belt-driven assembly 30 is implemented to include a cylinder.

[0050] refer to Figure 8 As a modified embodiment of the previous embodiment, the conveyor assembly 30 includes at least one elastic element 31 and a reset rod 32. The elastic element 31 is telescopically mounted between the lower mold body 121 and the mounting platform 122. When the mounting platform 122 drives the positioning rod 20 to move along the mold closing direction of the upper mold 11, the elastic element 31 undergoes elastic deformation and tends to drive the mounting platform 122 to move along the mold opening direction of the upper mold 11. The lower mold body 121 forms a moving channel 12104. The reset rod 32 passes through the moving channel 12104, and the top of the reset rod 32 partially extends out of the top wall of the lower mold body 121, while the bottom of the reset rod 32 is connected to the mounting platform 122. In this way, when the upper mold 11 and the lower mold 12 are closed, the upper mold 11 can squeeze the top of the reset rod 32.

[0051] refer to Figure 3 and Figure 4In this way, when the mold body 10 closes, the upper mold 11 presses against the portion of the reset rod 32 extending from the top wall of the lower mold body 121, causing the reset rod 32 to move the mounting platform 122 along the mold closing direction of the upper mold 11. The mounting platform 122 then moves the positioning rod 20 away from the placement space 12101 along the insertion channel 12103, separating the positioning rod 20 from the semi-finished product 900, ensuring that the lower circumference of the subsequently injection-molded product is free of depressions. Simultaneously, the elastic element 31 undergoes elastic deformation. When the mold body 10 opens, the elastic element 31, through its own elastic restoring force, moves the mounting platform 122 along the mold opening direction of the upper mold 11, causing the positioning rod 20 to be moved by the mounting platform 122 and extend into the placement space 12101 along the insertion channel 12103, allowing the positioning rod 20 to detect the placement posture of the semi-finished product 900. Therefore, the injection mold capable of detecting the position of the injection-molded semi-finished product does not require a drive mechanism to move the mounting platform 122 along the opening and closing direction of the upper mold 11, thereby reducing the overall weight of the mold. Furthermore, this allows the injection mold to detect the position of the injection-molded semi-finished product while simultaneously preventing interference with the injection molding of the semi-finished product during mold closing.

[0052] In one example, the elastic element 31 is implemented as a spring.

[0053] refer to Figure 5 and Figure 6 Furthermore, the injection mold capable of detecting the position of the injection-molded semi-finished product also includes at least one set of fixing components 40.

[0054] Specifically, the lower mold 12 forms a mounting groove 1201. Each set of fixing components 40 includes a telescopic member 41 and a fixing structure 42. The telescopic member 41 is movably mounted in the mounting groove 1201 in a transverse direction perpendicular to the mold closing direction of the upper mold 11. The fixing structure 42 includes a locking block 421 and a locking groove 422. The locking block 421 is disposed at the end of the telescopic member 41 and partially protrudes from the mounting groove 1201. The locking block 421 protruding from the mounting groove 1201 can be squeezed when the mounting platform 122 moves along the mold opening and closing direction of the upper mold 11, causing the telescopic member 41 to undergo elastic deformation and thus hide in the mounting groove 1201. Furthermore, the locking block 421 can engage with the locking slot 422 when the reset rod 32 is pressed by the upper mold 11, causing the mounting platform 122 to move along the mold closing direction of the upper mold 11 until the positioning rod 20 is withdrawn from the placement space 12101.

[0055] In one embodiment, the mounting groove 1201 is formed on the mounting platform 122, and the slot 422 is formed on the side of the lower mold body 121 facing the slot 421.

[0056] As a modified embodiment of the previous embodiment, the mounting groove 1201 is formed in the lower mold body 121, and the slot 422 is formed on the side of the mounting platform 122 facing the slot 421. To facilitate understanding of the technical solution of the present invention by those skilled in the art, the following embodiments are described based on this.

[0057] In this way, after the mold body 10 is opened, the mounting platform 122 maintains the positioning rod 20 in the state of being pulled out of the placement space 12101 through the engagement of the locking block 421 and the locking groove 422, thereby preventing the positioning rod 20 from directly extending into the placement space 12101 under the elastic action of the elastic member 31 and sticking to the injection-molded product, thus ensuring the quality of the product.

[0058] Preferably, the conveyor assembly 30 includes a pusher 33. The pusher 33 is connected to the lower mold body 121 and is used to push the mounting platform 122 to move along the opening direction of the upper mold 11. That is, when the pusher 33 pushes the mounting platform 122 to move along the opening direction of the upper mold 11, the locking block 421 is squeezed by the side wall of the mounting platform 122 and squeezes the telescopic member 41. The telescopic member 41 drives the locking block 421 to move in the direction of extending into the mounting groove 1201, so that the locking block 421 formed by the locking block 421 disengages from the groove 422.

[0059] Furthermore, the injection mold capable of detecting the position of the injection-molded semi-finished product also includes a limiting structure 50.

[0060] refer to Figure 8 Specifically, the limiting structure 50 includes a limiting member 51 and a limiting channel 52, wherein the limiting member 51 is movably mounted on the limiting channel 52. Either the limiting member 51 or the limiting channel 52 is disposed on the lower mold body 121, and the other is disposed on the mounting platform 122, to limit the movement direction of the mounting platform 122.

[0061] In a preferred embodiment, the limiting channel 52 is formed on the mounting platform 122, the limiting member 51 is mounted on the lower mold body 121, and the elastic member 31 is sleeved on the portion of the limiting member 51 that extends out of the limiting channel 52, so that the elastic member 31 can be stably extended and retracted.

[0062] Preferably, the bottom wall of the active space 12102 is recessed downward to form a limiting groove 12105, and the elastic member 31 is partially telescopically installed in the limiting groove 12105. The inner wall of the limiting groove 12105 is used to limit the elastic member 31 and increase the stability of the elastic member 31 when it is telescopic.

[0063] refer to Figure 1 and Figure 7 Preferably, the lower mold body 121 forms a molding protrusion 1211 by protruding upward from the bottom wall of the placement space 12101, and the semi-finished product 900 forms an insertion slot 90002 along the axial direction, and the molding protrusion 1211 allows the insertion slot 90002 formed by the semi-finished product 900 to be inserted.

[0064] refer to Figure 2 , Figure 3 , Figure 4 and Figure 7 Furthermore, the injection mold capable of detecting the position of the injection-molded semi-finished product also includes an installation position detection component 60.

[0065] Specifically, the installation position detection component 60 includes a movable component 61, a reset component 62, and a triggered component 63. The lower mold 12 forms a movable channel 1202 and an outlet 1203 communicating with the movable channel 1202. The movable component 61 is movably inserted into the movable channel 1202. A portion of the movable component 61 penetrates the bottom wall of the placement space 12101 to extend into the placement space 12101, providing a pressing portion for the semi-finished product 900. The portion of the movable component 61 extending into the placement space 12101 can be moved as a whole by the pressing action of the semi-finished product 900, and the end of the movable component 61 away from the placement space 12101 can move through the outlet 1203 in the direction of extending out of the movable channel 1202. The reset component 62 is connected to the movable component 61. The reset component 62 can elastically deform and tend to return to its original position when the movable component 61 moves under the pressure of the semi-finished product 900.

[0066] The triggered component 63 includes a triggered element 631. One end of the movable element 61, away from the placement space 12101, is disposed opposite to the triggered element 631. The triggered element 631 is communicatively connected to a controller 800 that controls the mold to perform operations. The movable element 61 can move closer to or further away from the triggered element 631.

[0067] In other words, when the semi-finished product 900 is placed on the lower mold 12 and the molding protrusion 1211 is inserted into the mounting slot 90002, if the semi-finished product 900 is installed in the preset position, the portion of the moving part 61 extending into the placement space 12101 will move as a whole due to the squeezing action of the semi-finished product 900. This causes the moving part 61 to move through the outlet 1203 in the direction of extending out of the active channel 1202 and come into contact with the triggered part 631. In this way, the controller 800 can communicate with the moving part 61 through the triggered part 631, and the mold can perform subsequent operations. If the semi-finished product 900 is not installed in the preset position, the moving part 61 will not be squeezed by the semi-finished product 900 and will not move. The controller 800 will then have a signal interruption between the triggered part 631 and the moving part 61, and the installation position of the semi-finished product 900 will need to be readjusted.

[0068] Furthermore, the triggered component 63 also includes an insulating housing 632. The triggered element 631 is mounted on the insulating housing 632, which protects the triggered element 631.

[0069] refer to Figure 3 It is worth mentioning that the insulating outer shell 632 forms a communicating space 63201. One end of the movable member 61 away from the placement space 12101 is movably inserted into the communicating space 63201 through the outlet 1203, so that the movable member 61 can move along the extension direction of the communicating space 63201 toward or away from the triggered member 631.

[0070] In one example, the reset member 62 is implemented as a spring, wherein the reset member 62 is sleeved on the moving member 61, and the triggered component 63 is implemented as including a contact switch.

[0071] This invention also provides a method for operating an injection mold capable of detecting the position and orientation of a semi-finished injection molded product, comprising the following steps:

[0072] (A) The semi-finished product 900 is placed in the placement space 12101 of the lower mold 12 so that the positioning rod 20 is inserted into the positioning notch 90001 formed by the semi-finished product 900;

[0073] (B) The upper mold 11 covers the lower mold 12 to form a product by injection molding;

[0074] (C) The upper mold 11 is opened to facilitate demolding.

[0075] (B1) The upper mold 11 covers the lower mold 12 and squeezes the portion of the reset rod 32 that extends out of the top wall of the lower mold 12, so that the reset rod 32 drives the mounting platform 122 and the positioning rod 20 connected to the mounting platform 122 to be pulled out of the placement space 12101.

[0076] In one embodiment, in step (C), the elastic member 31 drives the mounting platform 122 to move along the opening direction of the upper mold 11 by its own elastic restoring force, so that the positioning rod 20 is driven by the mounting platform 122 to extend into the placement space 12101 along the insertion channel 12103 to reset.

[0077] As a deformable addition, step (B2) is also included, wherein the locking block 421 engages with the slot 422 when the mounting platform 122 moves along the mold closing direction of the upper mold 11 until the positioning rod 20 is withdrawn from the placement space 12101.

[0078] It also includes a step (D), in which the pusher 33 drives the mounting platform 122 to move along the mold opening direction of the upper mold 11, so that the positioning rod 20 is driven by the mounting platform 122 and extends into the placement space 12101 along the insertion channel 12103 to reset.

[0079] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been demonstrated and explained in the embodiments; any variations or modifications can be made to the implementation of the present invention without departing from these principles.
