Slide mechanism for a mold

Abstract

The application discloses a mold slider mechanism, which comprises a sliding member and an inclined plug. The sliding member comprises a sliding seat, two sliding blocks and two elastic members. The two sliding blocks are horizontally slidably connected to the sliding seat and can move towards or away from each other. The moving direction of the sliding blocks is perpendicular to the moving direction of the sliding seat. The two sliding blocks jointly form a first gap and a second gap. When the sliding seat is partially arranged on the upper surface of the lower mold group at a predetermined position, the first gap and the second gap correspond to the low end and the high end of the inclined plug respectively. During the opening and closing of the mold, the inclined plug can cause the sliding member to make different actions. The mold slider mechanism of the application does not affect the closing action when the mold is closed. The sliding member is automatically separated from the molded product when the mold is opened. The working cycle is short, the additional power is not needed for the disassembly operation, and the overall structure is simple.

Description

Technical Field

[0001] This application relates to the field of mold technology, and in particular to slider mechanisms for molds. Background Technology

[0002] Molds are various shapes and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to create shaped articles; this tool is composed of various parts, and different molds are composed of different parts. A mold typically includes an upper mold assembly and a lower mold assembly; some molds also include lateral structures for docking with the lower mold assembly to participate in the molding process. In use, the lateral structure is driven to move closer to the lower mold assembly so that a portion is placed in a predetermined position on the upper surface of the lower mold assembly. The mold is then closed and reopened. After reopening, the lateral structure is again driven to move away from the lower mold assembly for demolding.

[0003] It is clear that the movement of the lateral structure is unrelated to the mold opening action. Demolding of the lateral structure often requires manual operation or a drive mechanism such as a cylinder or lead screw. Manual operation results in low efficiency, while a drive mechanism complicates the overall structure and increases costs. Furthermore, the demolding operation of the lateral structure is performed after the mold opening operation, leading to a longer overall work cycle and lower processing efficiency. Utility Model Content

[0004] To solve the aforementioned technical problems and achieve at least one advantage of this application, this application provides a slider mechanism for a mold, the slider mechanism for a mold comprising:

[0005] The sliding member includes:

[0006] A sliding seat, the sliding seat being defined to move horizontally toward the lower module so that it is partially positioned at a predetermined position on the upper surface of the lower module;

[0007] Two sliding blocks are horizontally slidably connected to the sliding seat, which can move closer to or further away from each other. The moving direction of the sliding blocks is perpendicular to the moving direction of the sliding seat. The two sliding blocks together form a first notch and a second notch. The second notch is opposite to the first notch and is located on the side of the sliding seat closer to the lower module. The portions of the two sliding blocks that form the first notch and the portions that form the second notch respectively form an inclined wall and an arc wall. With reference to the direction of horizontal movement of the sliding seat towards the lower module, the distance between the inclined walls of the two sliding blocks gradually decreases.

[0008] Two elastic elements, each elastic element having two ends corresponding to a sliding block and a sliding seat. The two elastic elements are compressed when the two sliding blocks are moved away from each other by an external force, and the two elastic elements are reset and moved closer to each other when the two sliding blocks are not moved by an external force.

When the sliding seat is placed at a predetermined position on the upper surface of the lower module, the first notch and the second notch correspond to the lower end and the upper end of the inclined insert, respectively. During the mold closing process, the inclined insert is driven downward by the upper module, so that the lower end of the inclined insert first inserts into the first notch and gradually extends into the first notch to apply pressure to the inclined walls of the two sliding blocks, thereby pushing the two sliding blocks away from each other. After the mold is closed, the inclined insert moves from the first notch to the second notch through the gap between the two sliding blocks, and the two sliding blocks are reset and move closer to each other under the elastic force of their respective elastic elements. During the mold opening process, the inclined insert is driven upward by the upper module along the second notch and applies pressure to the arc walls of the two sliding blocks to drive the sliding seat away from the lower module for demolding.

[0012] According to one embodiment of this application, the sliding seat includes a seat body and two connecting members. The seat body is defined to move horizontally to approach the lower module so that it is partially placed at a predetermined position on the upper surface of the lower module. The mounting hole and the clearance space are both formed in the seat body. The sliding block is inserted into the mounting hole at one end of the mounting hole away from the clearance space and extends into the clearance space. Each connecting member is detachably connected to the seat body and is located on the side of the mounting hole away from the clearance space. The two ends of each elastic member correspond to one connecting member and one sliding block.

[0029] The following description is intended to disclose this application 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 this application 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 this application.

[0030] Those skilled in the art should understand that, in the disclosure of this application, 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 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. Therefore, the above terms should not be construed as limitations on this application.

[0031] 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.

[0032] refer to Figures 1 to 10 A preferred embodiment of the mold slider mechanism according to this application will be described in detail below. The mold slider mechanism includes a sliding member 10, which includes a sliding seat 11, two sliding blocks 12, and two elastic members 13. The sliding seat 11 is configured to move horizontally to approach a lower module 80 so that it is partially positioned at a predetermined position on the upper surface of the lower module 80. The two sliding blocks 12 are horizontally slidably connected to the sliding seat 11, moving closer to or further away from each other, and the direction of movement of the sliding blocks 12 is perpendicular to the direction of movement of the sliding seat 11. Each elastic member 13 has two ends corresponding to one sliding block 12 and one sliding seat 11. The two elastic members 13 are compressed when the two sliding blocks 12 are moved away from each other by an external force, and the two elastic members 13 are reset and moved closer together when the two sliding blocks 12 are not subjected to an external force.

[0033] Preferably, the elastic element 13 is implemented as a spring.

[0034] It is worth mentioning that the two sliding blocks 12 together form a first notch 1201 and a second notch 1202. The second notch 1202 is opposite to the first notch 1201 and is located on the side of the sliding seat 11 near the lower module 80. The portions of the two sliding blocks 12 that form the first notch 1201 and the portions that form the second notch 1202 respectively form an inclined wall 121 and an arcuate wall 122. Taking the direction of horizontal movement of the sliding seat 11 towards the lower module 80 as a reference, the distance between the inclined walls 121 of the two sliding blocks 12 gradually decreases. The mold slider mechanism also includes an inclined insert 20, which is inclinedly disposed at the bottom of an upper module 90. When the sliding seat 11 is partially placed at a predetermined position on the upper surface of the lower module 80, the first notch 1201 and the second notch 1202 correspond to the lower end and the upper end of the inclined insert 20, respectively.

[0035] During mold closing, the inclined insert 20 is moved downward by the upper mold assembly 90, causing its lower end to first insert into the first notch 1201 and gradually extend into it to apply pressure to the inclined walls 121 of the two sliding blocks 12, pushing the two sliding blocks 12 away from each other. The sliding seat 11 remains partially at a predetermined position on the upper surface of the lower mold assembly 80 for subsequent molding. After mold closing, the inclined insert 20 moves from the first notch 1201 to the second notch 1202 through the gap between the two sliding blocks 12, and the two sliding blocks 12 return to their original positions and move closer to each other under the elastic force of their respective elastic members 13. During mold opening, the inclined insert 20 is moved upward along the second notch 1202 by the upper mold assembly 90 and applies pressure to the arcuate walls 122 of the two sliding blocks 12, causing the sliding seat 11 to move away from the lower mold assembly 80 for demolding.

[0036] During this process, the inclined insert 20 can cause the sliding component 10 to perform different actions during the mold opening and closing process. That is, this application can not affect the mold closing action when the mold is closed, and the sliding component 10 automatically separates from the processed product at the same time as the mold is opened. No additional power is required to drive the disassembly operation, the working cycle is short, the processing efficiency is relatively low, and the overall structure is simple.

[0037] Preferably, when the oblique insert 20 is inserted into the first notch 1201, the two sliding blocks 12 are symmetrically distributed in the plane containing the axis of the oblique insert 20, so that the two sliding blocks 12 move at the same distance when pushed by the oblique insert 20, so as to quickly increase the distance between the two sliding blocks 12.

[0038] Preferably, when the oblique insert 20 is inserted into the second notch 1202, the center of the arc wall 122 coincides with the center of the oblique insert 20, so that the contact area between the arc wall 122 and the oblique insert 20 is as large as possible, so that the sliding block 12 is subjected to uniform force, and then the sliding block 12 drives the sliding seat 11 to move away from the lower module 80.

[0039] Preferably, the sliding seat 11 has two oppositely arranged mounting holes 1101, and each of the sliding blocks 12 is slidably mounted on the sliding seat 11 with one end away from the first notch 1201 placed in one of the mounting holes 1101, so as to use the mounting holes 1101 to define the movement direction of the sliding block 12.

[0040] The sliding seat 11 also has a vertically extending clearance space 1102, with two mounting holes 1101 located on both sides of the clearance space 1102 and communicating with it. When the sliding block 12 is not subjected to external force, one end forming the first notch 1201 is placed in the clearance space 1102. The width of the clearance space 1102 is not less than the dimension of the inclined insert 20 in the moving direction of the sliding block 12, so that the inclined insert 20 can move smoothly up and down.

[0041] Further, the sliding seat 11 includes a body 111 and two connectors 112. The body 111 is designed to move horizontally to approach the lower module 80 so that it is partially positioned at a predetermined position on the upper surface of the lower module 80. The mounting hole 1101 and the clearance space 1102 are both formed in the body 111. The sliding block 12 is inserted into the mounting hole 1101 at one end of the mounting hole 1101 away from the clearance space 1102 and extends towards the clearance space 1102. Each connector 112 is detachably connected to the body 111 and located on the side of the mounting hole 1101 away from the clearance space 1102. The two ends of each elastic member 13 correspond to one connector 112 and one sliding block 12, so that a matching sliding block 12 can be replaced according to the size of the inclined insert 20.

[0042] refer to Figure 2 Preferably, the two sliding blocks 12 abut against each other when not subjected to external force. Each sliding block 12 has a guide hole 1203, and each elastic element 13 is engaged with one of the guide holes 1203. Both ends of each elastic element 13 abut against the end wall of the guide hole 1203 and a connecting member 112, respectively. In this way, after separating the connecting member 112 from the seat 111, the elastic element 13 and the sliding block 12 can be disassembled by successively pulling them out of the mounting hole 1101, or by pulling out the sliding block 12 with the elastic element 13 inserted into it along with the other end of the mounting hole 1101. This allows for individual replacement of the elastic element 13 if its elasticity is insufficient, or if the size of the sliding block 12 does not match the inclined insert 20, effectively reducing usage costs.

[0043] refer to Figures 2 to 3Furthermore, the portion of the seat 111 that forms the mounting hole 1101 forms a limiting step 1111. The sliding block 12 has an abutment portion 123. The sliding block 12 is inserted into the mounting hole 1101 such that the abutment portion 123 corresponds to the limiting step 1111. The limiting step 1111 is located in the direction in which the abutment portion 123 extends from the mounting hole 1101 toward the clearance space 1102, so as to prevent the sliding block 12 from completely moving out of the mounting hole 1101 from one end of the mounting hole 1101 near the clearance space 1102.

[0044] Preferably, the base 111 forms at least one recess 11101 communicating with the mounting hole 1101 on the outer side of each mounting hole 1101 away from the clearance space 1102, and the connector 112 is installed in the recess 11101 with the portion corresponding to the elastic member 13 placed at the port of the mounting hole 1101, so as to reduce the external space occupied by the connector 112.

[0045] Preferably, each of the mounting holes 1101 has two opposing recesses 11101 formed on the outer side of one port away from the clearance space 1102. Each of the connectors 112 is simultaneously engaged with the two opposing recesses 11101 and connected to the bottom wall of one of the recesses 11101 by at least one bolt, so that the connectors 112 are securely connected.

[0046] Preferably, the connector 112 has a insertion hole 11201, which includes a first hole portion 112011 and a second hole portion 112012. The first hole portion 112011 is in communication with the second hole portion 112012 and its size is smaller than that of the second hole portion 112012. The bolt connects the connector 112 to the base body 111 in such a way that its head abuts against the inner wall of the second hole portion 112012 and its shank passes through the first hole portion 112011 and is threaded to the inner wall of the countersunk groove 11101.

[0047] Preferably, the seat 111 includes a seat portion 1112 and a docking portion 1113. The mounting hole 1101, the clearance space 1102, and the recess 11101 are all formed in the seat portion 1112. The docking portion 1113 is mounted on the seat portion 1112. The docking portion 1113 is limited to horizontal movement and is driven to move together, so that the docking portion 1113 moves close to the lower module 80 so that it is partially placed at a predetermined position on the upper surface of the lower module 80.

[0048] Preferably, the docking part 1113 is detachably mounted to the seat part 1112 so that it can be replaced as needed.

[0049] In this embodiment, the docking part 1113 has a plug, and the seat 111 moves horizontally closer to the lower module 80 so that the plug is placed at a predetermined position on the upper surface of the lower module 80. The plug is then inserted into the end of the plug, and the mold is closed and opened to obtain the plug.

[0050] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application. The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
