Abstract
Description
Technical Field
[0001] This invention relates to the field of injection mold technology, and more particularly to injection molds and slider components used in injection molds. Background Technology
[0002] Two-stage injection molding refers to a process where plastic raw materials are first injected into a primary injection mold to create a semi-finished product. This semi-finished product is then placed into the lower mold of a secondary injection mold, and after the molds are closed, the same or different materials are injected again for a second injection molding process to create the final product. Therefore, two-stage molding can mold materials that cannot be molded simultaneously into individual parts.
[0003] Some products requiring secondary injection molding need to expose a portion of the pre-molded semi-finished product on its periphery. During the second injection molding, workers need to pre-place the semi-finished product in the molding space formed by the lower mold. When the upper mold closes, the wedge action between the guide pillars and guide grooves moves the molding part horizontally to cover part of the semi-finished product's upper surface, thus exposing this portion of the semi-finished product in the injection-molded product. However, due to human error in placement, some semi-finished products may be placed at a height higher than the installation height. As the molding part moves horizontally towards the semi-finished product, it may push against its side, causing scratches and shaking, altering the product's installation posture and rendering the finished product unusable. Summary of the Invention
[0004] One advantage of the present invention is that it provides an injection mold and a slider component for the injection mold, which can move the molding part to a preset height from the upper surface of the semi-finished product before fitting with the upper surface of the semi-finished product, so as to prevent the semi-finished product from being damaged by the lateral thrust of the molding part and to ensure the quality of the injection molded product.
[0005] Another advantage of the present invention is that it provides an injection mold and a slider component for the injection mold, which can adjust the installation position of the semi-finished product before injection molding so that the semi-finished product is adjusted to a preset installation position before injection molding.
[0006] Another advantage of the present invention is that it provides an injection mold and a slider component for the injection mold, which can drive the molding part to be removed from the product in a horizontal direction when the mold is opened after injection molding, so as to prevent it from sticking to the product.
[0007] Another advantage of the present invention is that it provides an injection mold and a slider component for the injection mold, which can convert the frictional force on the limiting member that fixes the height of the molding part into kinetic energy when the molding part moves in the vertical direction, thereby reducing the wear of the limiting member due to friction and extending the service life of the limiting member.
[0008] Another advantage of the present invention is that it provides an injection mold and a slider component for the injection mold, which enables the molding part to move vertically by means of the opening and closing motion of the upper mold and the force of the lifting member formed on the top wall of the lower mold on the molding part, without the need for a drive mechanism, thus making the slider component for the injection mold low in cost.
[0009] To achieve at least one of the above advantages of the present invention, the present invention provides a slider component for an injection mold, said slider component for an injection mold can be installed in a lower mold of an injection mold and can cooperate with an upper mold of the injection mold, wherein the lower mold forms a molding space, said molding space is configured to allow half of the finished product to be placed inside, said slider component for an injection mold includes:
[0010] A lifting member is provided on the top of the lower mold, wherein the lifting member forms an inclined lifting wall;
[0011] A slider assembly includes a sliding member and a forming member. The forming member is slidably mounted on the sliding member along the mold opening and closing direction. The forming member forms a forming portion at one end away from the sliding member. The sliding member forms a sliding structure, which corresponds in position and is adapted in size to an assembly structure formed by the upper mold. When the upper mold opens and closes, the sliding member is driven away from or towards the forming space in a horizontal direction perpendicular to the mold closing direction through the cooperation of the sliding structure and the assembly structure. A lifting wall is disposed on the movement trajectory of the sliding member driving the forming member to move away from the forming space. The lifting member is located below the forming member, and the angle between the direction in which the lifting wall extends towards the top wall of the upper mold and the direction in which the sliding member moves towards the forming space is an acute angle.
[0012] A limiting component is disposed between the conveyor and the molding component to fix the molding component at a preset height.
[0013] According to one embodiment of the present invention, a pressure wall is formed at the bottom of the molded part, wherein the pressure wall and the lifting wall are inclined in the same direction and are positioned opposite each other, and when the conveyor moves the molded part away from the molding space, the lifting wall compresses the pressure wall.
[0014] According to an embodiment of the present invention, the conveyor belt forms an inclined first abutment wall and an inclined second abutment wall on the conveyor belt structure. The first abutment wall extends from the top wall of the conveyor belt towards the lower mold, wherein the angle between the extension direction of the first abutment wall and the moving direction of the conveyor belt towards the molding space is an obtuse angle. The assembly structure forms a first pressure wall, the first pressure wall having the same inclination direction as the first abutment wall and corresponding in position. The second abutment wall extends from the top wall of the conveyor belt towards the lower mold, wherein the angle between the extension direction of the second abutment wall and the moving direction of the conveyor belt towards the molding space is an obtuse angle.

The telescopic member is mounted in the mounting groove, and the limiting member is connected to the telescopic member and partially extends out of the mounting groove. The portion of the limiting member extending out of the mounting groove is configured to be squeezed when the molded part moves along the mold opening direction, thereby causing the telescopic member to undergo elastic deformation. When the molded part moves to a preset height from the upper surface of the semi-finished product and the limiting member corresponds to the position of the first slot, the telescopic member causes the limiting member to engage with the first slot.
[0018] According to one embodiment of the present invention, the slider assembly forms a second slot at one end of the molded part facing the conveyor, the horizontal height of the second slot is lower than the horizontal height of the first slot, and when the molded part moves along the mold closing direction to abut against the upper surface of the semi-finished product, the telescopic member drives the limiting member to engage with the second slot.

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.
[0034] 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.
[0035] 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.
[0036] refer to Figures 1 to 5A preferred embodiment of the injection mold according to the present invention will be described in detail below. The injection mold includes at least one slider member 100 for injection molding and a mold body 200. The mold body 200 includes a lower mold 80 and an upper mold 90. The upper mold 90 is disposed above the lower mold 80 in an openable and closable manner. The slider member 100 for injection molding is mounted on the upper part of the lower mold 80. A portion of the top wall of the lower mold 80 is recessed downward to form a molding space 8001, which is configured to allow half of the finished product 900 to be inserted, such as... Figure 4 As shown.
[0037] Specifically, the slider component 100 for injection molds includes a lifting component 10, a slider assembly 20, and at least one limiting component 30.
[0038] The slider assembly 20 includes a conveyor belt 21 and a molding component 22. The molding component 22 is slidably connected to the conveyor belt 21 along the mold opening and closing direction. A molding portion 221 is formed at the end of the molding component 22 away from the conveyor belt 21. The conveyor belt 21 forms a conveyor belt structure 211. The upper mold 90 forms an assembly structure 91 that corresponds in position and is adapted in size to the conveyor belt structure 211.
[0039] refer to Figure 1 and Figure 2 When the upper mold 90 closes, the conveyor belt 21 is driven to move horizontally in a direction perpendicular to the mold closing direction through the cooperation of the conveyor belt structure 211 and the assembly structure 91. This causes the molding part 22 connected to the conveyor belt 21 to move horizontally toward the molding space 8001, so that the molding part 221 extends above the semi-finished product 900 located in the molding space 8001. When the upper mold 90 opens, the conveyor belt 21, through the cooperation between the conveyor belt structure 211 and the assembly structure 91, causes the molding part 22 to move away from the molding space 8001 in a horizontal direction, so that the molding part 221 is withdrawn from the molding space 8001 and separated from the semi-finished product 900.
[0040] refer to Figure 4 The limiting component 30 is disposed between the conveyor 21 and the molding component 22 to fix the molding component 22 at a preset height.
[0041] refer to Figure 4The lifting member 10 is formed on the top of the lower mold 80, wherein the lifting member 10 forms an inclined lifting wall 11. The lifting wall 11 is disposed on the movement trajectory of the moving member 21 driving the molding part 22 to move away from the molding space 8001. The lifting wall 11 is disposed below the molding part 22, and the angle between the direction in which the lifting wall 11 extends toward the top wall of the lower mold 80 and the direction in which the moving member 21 moves toward the molding space 8001 is acute.
[0042] refer to Figures 1 to 4 In this way, when the upper mold 90 opens, the conveyor belt 21, through the cooperation between the conveyor belt structure 211 and the assembly structure 91, drives the molded part 22 to move away from the molding space 8001. During this process, the molded part 22 is lifted upward along the mold opening direction by the pushing action of the lifting wall 11, so that the molded part 22 separates from the injection-molded product. Subsequently, under the limiting action of the limiting component 30, the molded part 22 is fixed at a preset height above the semi-finished product 900, so that the upper mold 90 moves again along the mold closing direction. After the slider assembly 20 is moved horizontally towards the molding space 8001 by a predetermined distance, the molding part 221 is suspended above the semi-finished product 900 without directly contacting it. This prevents the molding part 221 from shifting laterally and colliding with the semi-finished product 900, which is placed at a height higher than the installation height, and from shaking the semi-finished product 900. Subsequently, the upper mold 90 continues to move downward, causing the molding part 22 to adhere to the semi-finished product 900 and press the semi-finished product 900, which is not yet installed, down to the installation height so that a product that meets the requirements can be injection molded in the future.
[0043] refer to Figure 4 Preferably, the molded part 22 has a pressure wall 222 formed at its bottom, wherein the pressure wall 222 and the lifting wall 11 are inclined in the same direction and positioned opposite each other. When the conveyor 21 moves the molded part 22 away from the molding space 8001, the lifting wall 11 presses against the pressure wall 222, and the pressure wall 222 is subjected to uniform force, so that the molded part 22 can move upward smoothly.
[0044] In one embodiment, the conveyor belt structure 211 is implemented as a guide groove, and the assembly structure 91 is implemented as a guide post. When the upper mold 90 opens and closes, it causes the assembly structure 91 to be pushed out or inserted into the conveyor belt structure 211.
[0045] Specifically, the conveyor 21 forms an inclined first abutment wall 212 on the conveyor structure 211. The first abutment wall 212 extends from the top wall of the conveyor 21 towards the lower mold 80, wherein the angle between the extension direction of the first abutment wall 212 and the moving direction of the conveyor 21 toward the molding space 8001 is obtuse. The assembly structure 91 forms a first pressure wall 911, which has the same inclination direction and corresponding position as the first abutment wall 212. In this way, when the upper mold 90 drives the assembly structure 91 to close, the assembly structure 91 gradually extends into the conveyor structure 211 and presses the first abutment wall 212 through the first pressure wall 911, causing the conveyor 21 to drive the molded part 22 to move toward the molding space 8001.
[0046] The conveyor 21 further forms an inclined second abutment wall 213 on the conveyor structure 211. The second abutment wall 213 extends from the top wall of the conveyor 21 towards the lower mold 80, wherein the angle between the extension direction of the second abutment wall 213 and the moving direction of the conveyor 21 toward the molding space 8001 is obtuse. The first abutment wall 212 and the second abutment wall 213 are opposite to each other. The assembly structure 91 further forms a second pressure wall 912, which has the same inclination direction as the second abutment wall 213 and is positioned correspondingly. In this way, when the upper mold 90 drives the assembly structure 91 to open, the assembly structure 91 gradually moves out of the conveyor structure 211 and presses the second abutment wall 213 through the second pressure wall 912, causing the conveyor 21 to drive the molded part 22 to move away from the molding space 8001.
[0047] As a modified embodiment of the previous embodiment, the shifting structure 211 is implemented as a guide post and the assembly structure 91 is implemented as a guide groove, which will not be described in detail here.
[0048] refer to Figure 6 Preferably, the slider assembly 20 further includes a limiting structure 23 for limiting the movement of the molded part 22 along the mold opening and closing direction.
[0049] Specifically, the limiting structure 23 includes at least one limiting protrusion 231 and at least one limiting groove 232. The limiting protrusion 231 is inserted into the limiting groove 232. Either the limiting protrusion 231 or the limiting groove 232 is formed at one end of the conveyor 21 facing the molded part 22, and the other is formed at one end of the molded part 22 facing the conveyor 21.
[0050] refer to Figure 4Preferably, the conveyor belt 21 further includes a guide structure 214. The guide structure 214 includes at least one guide protrusion 2141 and at least one guide groove 2142, wherein the guide protrusion 2141 is inserted into the guide groove 2142. Either the guide protrusion 2141 or the guide groove 2142 is formed on the side of the lower mold 80 facing the conveyor belt 21, and the other is formed on the side of the conveyor belt 21 facing the lower mold 80.
[0051] In a preferred embodiment, the guide groove 2142 is formed on the conveyor 21. The guide protrusion 2141 is formed on the lower mold 80, and at least a portion of the guide protrusion 2141 is located on the trajectory of the molded part 22 moving away from the molding space 8001. The height of the guide protrusion 2141 is the same as the maximum height of the lifting member 10, so that when the injection mold is reset, the guide protrusion 2141 and the limiting component 30 together provide support for the molded part 22.
[0052] refer to Figure 4 It is worth mentioning that the slider assembly 20 forms a mounting groove 2001 and a first slot 2002. The limiting assembly 30 includes a limiting member 31 and a telescopic member 32. The telescopic member 32 is installed in the mounting groove 2001, and the limiting member 31 is connected to the telescopic member 32 and partially extends out of the mounting groove 2001. The portion of the limiting member 31 extending out of the mounting groove 2001 is configured to be squeezed when the molded part 22 moves along the mold opening direction of the upper mold 90, thereby causing the telescopic member 32 to elastically deform, so that the telescopic member 32 tends to drive the limiting member 31 to return to its original position. When the molded part 22 moves to a preset height from the upper surface of the semi-finished product 900 and the limiting member 31 corresponds to the position of the first slot 2002, the telescopic member 32 drives the limiting member 31 to engage with the first slot 2002, thereby fixing the molded part 22 to the preset height.
[0053] In one embodiment, the mounting groove 2001 is formed at one end of the conveyor 21 facing the molded part 22, and the first slot 2002 is formed at one end of the molded part 22 facing the conveyor 21.
[0054] As a modified embodiment of the previous embodiment, the end of the conveyor 21 facing the molded part 22 forms the first slot 2002, and the end of the molded part 22 facing the conveyor 21 forms the mounting slot 2001.
[0055] refer to Figure 3Preferably, the slider assembly 20 further forms a second slot 2003 opposite to the limiting member 31. The horizontal height of the second slot 2003 is lower than that of the first slot 2002. When the molded part 22 moves along the mold closing direction of the upper mold 90 to abut against the upper surface of the semi-finished product 900, the telescopic member 32 drives the limiting member 31 to engage with the second slot 2003, thereby reducing the pressure on the telescopic member 32 and extending the service life of the telescopic member 32.
[0056] In a preferred embodiment, the telescopic member 32 is implemented as a spring, and the limiting member 31 is implemented as a ball. The ball is rotatably connected to the spring. That is, when the molded part 22 moves along the mold opening direction, the ball rotates due to the frictional force of the conveyor 21 or the molded part 22, thereby converting sliding friction into kinetic energy, thereby reducing the wear of the limiting member 31 caused by friction and extending the service life of the limiting member 31.
[0057] Preferably, the lifting member 10 is formed at a predetermined horizontal distance between the lower mold 80 and the edge of the molding space 8001. In this way, when the upper mold 90 opens, the conveyor 21 moves the molding part 22 horizontally away from the molding space 8001 by a predetermined distance, so that the molding part 221 is horizontally removed from the upper surface of the semi-finished product 900, thus preventing the molding part 221 from sticking to the injection-molded product during the mold opening process and ensuring the quality of the injection-molded product. Subsequently, the molding part 22 is pushed by the lifting wall 11 and moves along the mold opening direction to reset, facilitating subsequent processing.
[0058] The present invention also provides the working principle of the injection mold and the slider component for the injection mold, including the following steps:
[0059] (A) The semi-finished product 900 is placed in the molding space 8001;
[0060] (B) The upper mold 90 covers the lower mold 80;
[0061] (C) The upper mold is opened at 90 degrees.
[0062] (b1) The upper mold 90 forms the assembly structure 91. The belt shifting structure 211 drives the belt shifting member 21 to move in a horizontal direction perpendicular to the mold closing direction, thereby driving the molding member 22 connected to the belt shifting member 21 to move in a horizontal direction close to the molding space 8001 until the molding part 221 extends above the semi-finished product 900 located in the molding space 8001.
[0063] (b2) The upper mold 90 presses down on the molded part 22 so that the molded part 22 is attached to the semi-finished product 900 and the semi-finished product 900 that is not installed in place is pressed down to the installation height.
[0064] (c1) The upper mold 90 forms the assembly structure 91. The belt transfer structure 211 drives the belt transfer member 21 to move in a horizontal direction perpendicular to the mold closing direction, thereby driving the molding part 22 connected to the belt transfer member 21 to move in a horizontal direction away from the molding space 8001 until the molding part 221 is extracted from the molding space 8001 and separated from the injection molded product.
[0065] (c2) The molded part 22 is lifted by the lifting wall 11 and moves upward along the opening direction of the upper mold 90, and is fixed at a preset height by the limiting component 30 so that the molded part 22 can be reset.
[0066] 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.

7. The slider component for injection molds according to claim 6, characterized in that, The slider assembly forms a second slot at one end of the molded part facing the conveyor. The horizontal height of the second slot is lower than that of the first slot. When the molded part moves along the mold closing direction to abut against the upper surface of the semi-finished product, the telescopic member drives the limiting member to engage with the second slot.
8. The slider component for injection molds according to claim 7, characterized in that, The lifting element is formed at a predetermined horizontal distance between the lower mold and the edge of the forming space.
9. The slider component for injection molds according to claim 8, characterized in that, The telescopic member is implemented as a spring, and the limiting member is implemented as a ball. The ball is rotatably connected to the spring, and the ball rotates due to the friction of the molded part when the molded part moves along the mold opening direction.
10. An injection mold, characterized in that, The injection mold includes: At least one slider component for injection molds as described in any one of claims 1 to 9; A mold body includes a lower mold and an upper mold. The upper mold is disposed above the lower mold in an openable and closable manner. The top wall of the lower mold is recessed downward to form a molding space. The molding space is configured to allow half of the finished product to be placed inside. The top wall of the lower mold forms the lifting member. The upper mold forms at least one assembly structure that corresponds to the position of the sliding structure and is adapted in size.
