Abstract
Description
Technical Field
[0001] This application relates to the field of mold technology, and more specifically to a novel mold opening and closing device structure. Background Technology
[0002] A mold is a tool used to shape a blank into a part with a specific shape and size under the action of external force. It has a specific contour or internal cavity shape and usually includes a fixed mold and a movable mold that can be separated and joined.
[0003] Existing mold opening and closing mechanisms include the following three types: 1. Controlling the mold opening stroke by setting the length of a tie rod; 2. Using a nylon opening and closing mechanism to control the mold opening and closing sequence; 3. Controlling the mold opening stroke by setting the displacement of an equal-height screw. For the tie rod structure in type one, its function is limited; it can only control the mold opening stroke and can only be used inside the mold, failing to meet the mold action requirements for more complex mold movements. For the nylon opening and closing mechanism in type two, it mainly relies on the friction of the nylon itself to control the mold opening sequence but cannot control the mold opening stroke; this type of opening and closing mechanism has low stability and service life. For the equal-height screw structure in type three, it can only control the mold opening stroke, and the stroke range is limited; it can only be used inside the mold, failing to meet the mold requirements for more complex mold movements.
[0004] Therefore, there is a need for a new type of mold opener / closer structure that can be used on the outside of the mold, does not occupy the internal space of the mold, and is suitable for applications involving the sequential separation of moving molds. Summary of the Invention
[0005] The main objective of this application is to provide a novel mold opening and closing device structure, disposed on a mold body. The mold body includes, from top to bottom, a runner plate, a first plate, a second plate, a support plate, and a base plate. The runner plate, the first plate, and the second plate are all vertically mounted on an external base. The first plate and the second plate each have a mold cavity at the end closest to the runner plate. The novel mold opening and closing device structure includes a following rod, a swing rod, and a limiting block. One end of the following rod is fixedly mounted on the runner plate. The first plate has a groove, and the limiting block is fixedly mounted on the swing rod. The swing rod is rotatably mounted on the base plate at one end away from the limiting block. When the swing rod rotates a predetermined angle, the limiting block extends into the groove and restricts the first plate from moving upward, or the limiting block disengages from the groove. When the limiting block extends into the groove, the first plate cannot move upward. As the flow channel plate moves further upward, the swing rod swings a predetermined angle, causing the limiting block to disengage from the groove and the first plate to move upward and separate from the second plate, thus realizing the secondary separation of the movable mold. In addition, compared with the prior art, it has the advantage of being used on the outside of the mold and not occupying the internal space of the mold.
[0006] Another objective of this application is to provide a novel mold opening and closing device structure, wherein the following rod has a protrusion, and the two ends of the protrusion have two first guide slopes. The swing rod has a fixing pin at one end near the flow channel plate. The fixing pin is directly opposite the first guide slope in the height direction. When the following rod moves upward and the first guide slope contacts the fixing pin, the swing rod rotates a predetermined angle away from the first plate, so that the swing rod swings when the following rod moves upward.
[0007] To achieve at least one of the above-mentioned objectives, this application provides a novel mold opening and closing device structure, disposed on a mold body. The mold body includes a runner plate, a first plate, a second plate, a support plate, and a bottom plate, arranged sequentially from top to bottom. The runner plate, the first plate, and the second plate are all vertically mounted on an external base. The first plate and the second plate each have a mold cavity at one end near the runner plate. The novel mold opening and closing device structure includes: The novel mold opening and closing device structure includes a follower rod, a swing rod, and a limiting block. One end of the follower rod is fixedly installed on the flow channel plate. The first plate has a groove. The limiting block is fixedly installed on the swing rod. The end of the swing rod away from the limiting block is rotatably installed on the base plate. When the swing rod rotates a predetermined angle, the limiting block extends into the groove and restricts the first plate from moving upward, or the limiting block disengages from the groove.
[0008] In one or more embodiments of this application, the follower rod has a protrusion, and the two ends of the protrusion have two first guide slopes. The end of the swing rod near the flow channel plate has a fixing pin, and the fixing pin is directly opposite the first guide slope in the height direction. When the follower rod moves upward and the first guide slope contacts the fixing pin, the swing rod rotates a predetermined angle away from the first plate.
[0009] In one or more embodiments of this application, the novel mold opening and closing device structure further includes a reset elastic element, which is fixedly installed on the base plate, and one end of the reset elastic element abuts against the end of the swing rod away from the flow channel plate.
[0010] In one or more embodiments of this application, the novel mold opening and closing device structure further includes a guide member, which is fixedly installed on the swing rod. The middle section of the protrusion is a plane. When the first plate and the second plate abut against each other, one end of the guide member fits against the middle section of the protrusion.
[0011] In one or more embodiments of this application, the limiting block has a second guide slope, and the first plate also has a third guide slope.
[0012] In one or more embodiments of this application, the reset elastic member is integrally sheet-like, and the middle section of the reset elastic member is arch-shaped.
[0013] In one or more embodiments of this application, the follower rod has a guide groove, and the protrusion is disposed in the guide groove and detachably connected to the follower rod.
[0014] In one or more embodiments of this application, the base plate has a mounting groove, and the novel mold opening and closing device structure further includes a mounting block. One end of the mounting block extends into the mounting groove and is detachably connected to the base plate. One end of the reset elastic element is fixedly mounted on the mounting block, and one end of the swing rod away from the limiting block is rotatably mounted on the mounting block.
[0015] In this embodiment, the novel mold opening and closing device structure is disposed on the mold body. The mold body includes a runner plate, a first plate, a second plate, a support plate, and a bottom plate, arranged sequentially from top to bottom. The runner plate, the first plate, and the second plate are all elliptically mounted on an external base. The first plate and the second plate each have a mold cavity at the end near the runner plate.

[0017] The terms and words used in the following specification and claims are not limited to their literal meaning, but are used solely by the inventors to enable a clear and consistent understanding of this application. Therefore, it will be apparent to those skilled in the art that the following description of various embodiments of this application is provided for illustrative purposes only and not for the purpose of limiting the application as defined in the appended claims and their equivalents.
[0018] 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.
[0019] While ordinal numbers such as "first," "second," etc., will be used to describe various components, there is no limitation on which components are used herein. The term is used only to distinguish one component from another. For example, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component, without departing from the teachings of the utility model concept. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0020] The terminology used herein is for the purpose of describing various embodiments only and is not intended to be limiting. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.
[0021] Schematic illustration of a novel mold opening and closing device structure, for reference Figures 1 to 5 According to a preferred embodiment of the present invention, a novel mold opening and closing device structure is provided, such as... Figure 1 As shown, the mold body 10 includes a runner plate 101, a first plate 102, a second plate 103, a support plate 104, and a base plate 105 arranged sequentially from top to bottom. The runner plate 101 and the first plate 102 are both elliptically mounted on an external base. The first plate 102 and the second plate 103 have a mold cavity 1021 at one end near the runner plate 101.
[0022] It should be noted that the external base has a lifting drive device, and both the flow channel plate 101 and the first plate 102 move up and down through the lifting drive device. Since how the lifting drive device sequentially moves the flow channel plate 101 and the first plate 102 upwards is common knowledge in the art, it will not be elaborated here. A common practice is to install insert rods on the side walls of the flow channel plate 101 and the first plate 102, with the insert rods extending into a lifting component with an oblong hole. The insert rod on the flow channel plate 101 is located at the top of the oblong hole, and the insert rod on the first plate 102 is located in the middle of the oblong hole. When the lifting drive device moves the flow channel plate 101 upwards, the lifting component moves upwards accordingly. However, since the insert rod on the first plate 102 is spaced a predetermined distance from the bottom of the oblong hole, there is a period of idle travel until the insert rod on the first plate 102 contacts the bottom of the oblong hole. Then, the lifting drive device moves the first plate 102 upwards through the lifting component.
[0023] Furthermore, such as Figures 1 to 3 As shown, the novel mold opening and closing device structure includes a follower rod 20, a swing rod 30, and a limiting block 40. One end of the follower rod 20 is fixedly installed on the flow channel plate 101. The first plate 102 has a groove 1022. The limiting block 40 is fixedly installed on the swing rod 30. The end of the swing rod 30 facing away from the limiting block 40 is rotatably installed on the base plate 105. When the swing rod 30 rotates a predetermined angle, the limiting block 40 extends into the groove 1022 and restricts the first plate 102 from moving upward, or the limiting block 40 disengages from the groove 1022.
[0024] It should be noted that, referring to Figure 1 and Figure 5Under normal conditions, the swing rod 30 is vertically arranged, and the limiting block 40 extends into the groove 1022. When the lifting drive device moves the flow channel plate 101 upwards, the first plate 102 is restricted by the limiting block 40. Therefore, only the flow channel plate 101 moves upwards, while the first plate 102, the second plate 103, the support plate 104, and the bottom plate 105 remain fixed, exposing the mold cavity 1021 on the first plate 102. As the flow channel plate 101 moves further upwards a predetermined distance, it follows the flow... When the follower rod 20 moves upward on the channel plate 101, it applies a force to the swing rod 30, causing the swing rod 30 to rotate a predetermined angle away from the first plate 102, and causing the limiting block 40 to disengage from the groove 1022. At this time, as the lifting drive device drives the flow channel plate 101 to move further upward, the first plate 102 will also move upward a predetermined distance, realizing the secondary separation of the movable mold. It is evident that, compared with the prior art, this application has the advantages of being used on the outside of the mold, not occupying the internal space of the mold, and being suitable for the application scenario of secondary separation of the movable mold.
[0025] Furthermore, to achieve the goal of moving the flow channel plate 101 upward a predetermined distance, the swing rod 30 rotates by a predetermined angle in the direction away from the first plate 102, such as... Figure 2 As shown, the follower rod 20 has a protrusion 201, and the two ends of the protrusion 201 have two first guide slopes 2011. The swing rod 30 has a fixing pin 301 at one end near the flow channel plate 101, and the fixing pin 301 is directly opposite the first guide slope 2011 in the height direction.
[0026] It should be noted that when the following rod 20 moves upward and the first guide slope 2011 contacts the fixing pin 301, the swing rod 30 rotates by a predetermined angle in the direction away from the first plate 102.
[0027] Furthermore, to ensure that after the protrusion 201 passes through the fixing pin 301, the swing rod 30 returns to a vertically arranged state, as follows: Figure 2 As shown, the novel mold opening and closing device structure also includes a reset elastic element 50, which is fixedly installed on the base plate 105, and one end of the reset elastic element 50 abuts against the end of the swing rod 30 away from the flow channel plate 101.
[0028] Specifically, in this application, the reset elastic member 50 is generally in the form of a sheet, and the middle section of the reset elastic member 50 is in the shape of an arch bridge.
[0029] Furthermore, to improve stability during movement, such as Figure 2 As shown, the novel mold opening and closing device structure also includes a guide member 302, which is fixedly installed on the swing rod 30. The middle section of the protrusion 201 is a plane. When the first plate 102 and the second plate 103 abut against each other, the side wall of one end of the guide member 302 fits against the middle section of the protrusion 201.
[0030] It should be noted that, in the initial stage of the movement, as the following rod 20 moves upward, the side wall of the guide member 302 fits against the middle section of the protrusion 201, thereby guiding the flow channel plate 101 in the initial stage of its upward movement.
[0031] Furthermore, to achieve mold closure, such as Figure 4 As shown, the limiting block 40 has a second guide slope 401, and the first plate 102 also has a third guide slope 1023.
[0032] It should be noted that, assuming that the first plate 102 and the flow channel plate 101 have both moved upward a predetermined distance, in order to move the first plate 102 and the flow channel plate 101 downward and reset them, as the first plate 102 moves downward, the third guide slope 1023 on the first plate 102 first contacts the second guide slope 401 on the limiting block 40, and then the swing rod 30 swings a predetermined angle away from the first plate 102 so that the first plate 102 can move downward smoothly.
[0033] Furthermore, to prevent the protrusion 201 from tilting during installation, such as... Figure 2 As shown, the follower rod 20 has a guide groove 202, and the protrusion 201 is disposed in the guide groove 202 and is detachably connected to the follower rod 20 by means of bolts.
[0034] Furthermore, to specifically realize the installation of the reset elastic element 50 and the swing rod 30 on the base plate 105, as follows: Figure 2 As shown, the base plate 105 has a mounting groove 1051, and the novel mold opening and closing device structure also includes a mounting block 1052. One end of the mounting block 1052 extends into the mounting groove 1051 and is detachably connected to the base plate 105. One end of the reset elastic member 50 is fixedly mounted on the mounting block 1052, and one end of the swing rod 30 away from the limiting block 40 is rotatably mounted on the mounting block 1052.
[0035] In summary, the novel mold opening and closing device structure based on the embodiments of this application has been clarified, which provides advantages such as being used on the outside of the mold, not occupying the internal space of the mold, and being suitable for application scenarios of secondary sequential separation of moving molds.
[0036] 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 present invention. The purpose of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from these principles.
