Description

Technical Field

[0001] This utility model belongs to the technical field of molds for product molding, and specifically relates to a multi-directional linkage demolding mold. Background Technology

[0002] In the field of injection molding, products with complex structures and multiple undercuts or side protrusions typically require multiple mold cores for demolding. This is especially true for products with strict appearance requirements that cannot have obvious parting lines, such as... Figure 1 (Front of the product) and Figure 2 The product shown (on the back of the product) is used for a water tank base. The product's sidewalls have multiple protruding parts. Traditional demolding methods using two integral mold cores sliding relative to each other cannot achieve smooth demolding. Therefore, multiple movable mold cores must be set in both the moving and fixed molds, and these cores must move synchronously or sequentially in different directions during mold opening to ensure successful demolding. For complex structures requiring multiple movable mold cores (e.g., including vertically sliding cores, horizontally sliding cores, etc.) within the same mold, existing molds often lack a unified driving and coordination mechanism. This leads to asynchronous movement of the mold cores during mold opening, causing interference or incomplete demolding, affecting production efficiency and product yield.

[0003] Therefore, there is an urgent need for a mold structure that can achieve multi-directional, large-angle, synchronous and stable demolding, in order to solve the limitations of existing demolding mechanisms, such as poor movement, poor coordination, and applicability to complex products. Utility Model Content

[0004] This invention provides a multi-directional linkage demolding mold, which aims to solve the problem in the prior art that when using molds with multiple mold cores to form products, it is impossible to drive all mold cores to move synchronously in different directions to achieve demolding.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A multi-directional linkage demolding mold, comprising:

[0007] The mold body includes a first main body and a second main body that open and close relative to each other. The first main body is provided with a first mold core, and the second main body is provided with a second mold core. A third mold core is slidably provided on the second main body. A fourth mold core is slidably connected to the first main body. The first mold core, the second mold core, the third mold core, and the fourth mold core form a product forming cavity when the mold is closed.

[0008] A first oblique guide mechanism is disposed between the third mold core and the first body. The first oblique guide mechanism is used to convert the opening and closing movement of the first body relative to the second body into the movement of the third mold core away from or towards the product.

[0009] A second oblique guide mechanism is disposed between the fourth mold core and the first body. The second oblique guide mechanism is used to convert the opening and closing movement of the first body relative to the second body into movement of the fourth mold core away from or towards the product; and...

[0010] A reset mechanism is used to drive the fourth mold core to slide in the opposite direction to the product relative to the mold opening direction of the first body.

[0011] When the mold is opened, the first body and the first mold core move away from the second body and the second mold core to demold, and the first body drives the third mold core to move along the first direction to demold through the first oblique guide mechanism, and the first body drives the fourth mold core to move along the second direction opposite to the first direction to demold through the second oblique guide mechanism.

[0012] A further embodiment: the first main body opens and closes by moving relative to the second main body in the vertical direction; the third mold core is slidably disposed on the second main body in the horizontal direction;

[0013] The first main body drives the third mold core to move to the right and demold through the first oblique guide mechanism, and the first main body drives the fourth mold core to move to the left and demold through the second oblique guide mechanism.

[0014] Based on the above technical solution: by converting the main mold opening motion (the first mold core moving upward away from the second mold core) into the rightward demolding motion of the third mold core and the leftward demolding motion of the fourth mold core through different oblique guide mechanisms, the simultaneous demolding of multiple mold cores can be achieved, effectively solving the interference problem when demolding multi-undercut products, and the structure is more optimized.

[0015] A further option: The second inclined guide mechanism includes:

[0016] The second inclined ejector block has its upper end slidingly engaged with the reset mechanism, and its lower end integrally formed with or fixedly connected to the fourth mold core; and...

[0017] A second oblique guide hole is provided on the first mold core, and the second oblique top block is provided through the second oblique guide hole.

[0018] Based on the above technical solution: by setting a second oblique guide hole on the first mold core and a second oblique ejector block on the fourth mold core, when the first mold core moves upward to open the mold, the fourth mold core will be driven to move to the left to demold through the cooperation of the second oblique guide hole and the second oblique ejector block.

[0019] A further option: The second inclined guide mechanism also includes:

[0020] A second inclined guide post is disposed on the first main body; and...

[0021] The second inclined top seat is disposed at the upper end of the second inclined top block and is slidably connected to the reset mechanism in the left-right direction. The second inclined top seat is provided with a third inclined guide hole that cooperates with the second inclined guide post. The second inclined top seat is provided with a second inclined guide groove. The second inclined guide groove gradually slopes upward from right to left. The upper end of the second inclined top block is slidably connected to the second inclined guide groove.

[0022] The second inclined guide post, the second inclined guide hole, the second inclined top block, and the third inclined guide hole have the same inclination direction, and all of them gradually tilt from top to bottom and to the left.

[0023] Based on the above technical solution: by fixing a second inclined guide post on the first main body and setting a second inclined ejector seat on the upper end of the second inclined ejector block, and with the second inclined ejector seat slidably connected to the reset mechanism in the left-right direction, and the upper end of the second inclined ejector block slidingly engaging with the second inclined guide groove, during demolding, the first main body and the first mold core synchronously move upward away from the second main body and the second mold core. Simultaneously, the reset mechanism drives the second inclined ejector seat and the second inclined ejector block to move downward relative to the first main body. The inclined engagement of the second inclined guide post and the third inclined guide hole drives the second inclined ejector seat to slide to the left, and the inclined engagement of the second inclined ejector block and the first mold core drives the fourth mold core to slide to the left for demolding. This achieves synchronous leftward movement of the second inclined ejector seat, the second inclined ejector block, and the fourth mold core. Simultaneously, the second inclined ejector block slightly moves from right to left along the second inclined guide groove, allowing the lower end of the fourth mold core to be demolded from the product. This combination of features avoids interference during demolding and prevents damage to the product.

[0024] A further embodiment: the inclination angle of the second inclined guide post, the second inclined guide hole, the second inclined top block, and the third inclined guide hole is 12-30 degrees.

[0025] A further embodiment: The reset mechanism includes:

[0026] A top plate assembly is slidably disposed on the first main body in the vertical direction; a second inclined top seat is located below the top plate assembly and is slidably connected to the top plate assembly in the horizontal direction; and...

[0027] An elastic reset component is used to drive the top plate assembly to slide downward relative to the first body, and the second inclined top seat is slidably disposed on the top plate assembly in the left-right direction.

[0028] Based on the above technical solution: the above settings enable the first main body and the first mold core to move upward and demold when the mold is opened. At the same time, the elastic reset component drives the top plate component to move downward relative to the first main body under its own reset action. Combined with the guiding action of the second inclined guide mechanism, the fourth mold core can move to the left stably and demold.

[0029] A further embodiment: The first main body is provided with a first mounting cavity, the top plate assembly is slidably disposed in the first mounting cavity in the up-down direction, at least one first guide post is fixedly disposed on the top plate assembly, and the first main body is provided with a first guide hole that cooperates with the first guide post.

[0030] Based on the above technical solution: the top plate assembly can achieve a stable sliding fit with the first body through the first guide post. At the same time, during the mold opening process, when the top plate assembly slides downward relative to the first body and abuts against the bottom wall of the first mounting cavity, the first mold opening action is completed, that is, the first mold core, the third mold core and the fourth mold core are all separated from the key structure on the product. After that, the first body and the first mold core will be driven by the top plate assembly, the second inclined ejector and the second inclined ejector block to move the fourth mold core upward for a distance, completing the second mold opening action, which makes it convenient for the user to take out the product later.

[0031] A further embodiment: The elastic reset component includes:

[0032] At least one first return spring is disposed between the upper side of the top plate assembly and the upper top wall of the first mounting cavity; and / or,

[0033] At least one second return spring is disposed between the limiting step in the corresponding first guide hole and the limiting abutment at the lower end of the first guide post and is sleeved on the first guide post.

[0034] Based on the above technical solution: the setting of the first reset spring and the second reset spring ensures that when the first mold core and the first body move upward to open the mold, the reset action of the first reset spring and the second reset spring can prevent the fourth mold core from being driven upward, thereby enabling the fourth mold core to always move stably to the left to demold.

[0035] A further embodiment: The top plate assembly is provided with:

[0036] A first clearance hole is provided, and a second inclined guide post is disposed through the first clearance hole; and...

[0037] The first guide groove is slidably disposed in the second inclined top seat in the left-right direction, and under the action of the elastic reset component, the upper top wall of the first guide groove abuts against the second inclined top seat.

[0038] A further solution: a multi-directional linkage demolding mold, further comprising:

[0039] The fifth mold core is located in front of the fourth mold core, and a third oblique guide mechanism is provided between the first main body and the fifth mold core;

[0040] The sixth mold core is located behind the fourth mold core, and a fourth oblique guide mechanism is provided between the first main body and the sixth mold core;

[0041] When the mold is opened, the first body and the first mold core move upward away from the second body and the second mold core to demold. The first body drives the fifth mold core to move from front to back to demold through the third oblique guide mechanism. The first body drives the sixth mold core to move from back to front to demold through the fourth oblique guide mechanism.

[0042] Based on the above technical solution: the fifth and sixth mold cores are used for molding and demolding the protruding structures of the front and rear sidewalls of the product. By setting the third and fourth oblique guide mechanisms and utilizing the mold opening movement of the first main body, the fifth and sixth mold cores can be synchronously driven to move in opposite directions for demolding. This allows a single mold to handle products with more directional and more complex undercut structures, greatly improving the versatility and demolding efficiency of the mold.

[0043] A further embodiment: The third oblique guide mechanism includes:

[0044] A fourth oblique guide hole is provided on the first mold core; and,

[0045] The third inclined ejector block is inserted into the fourth inclined guide hole. The upper end of the third inclined ejector block is slidably connected to the top plate assembly in the left-right direction, and the lower end of the third inclined ejector block is integrally formed or fixedly connected to the fifth mold core. The fourth inclined guide hole and the third inclined ejector block are both inclined from top to bottom and gradually backward.

[0046] The fourth oblique guide mechanism includes:

[0047] A fifth oblique guide hole is provided on the first mold core; and,

[0048] The fourth inclined top block is inserted into the fifth inclined guide hole. The upper end of the fourth inclined top block is slidably connected to the top plate assembly in the left-right direction, and the lower end of the fourth inclined top block is integrally formed or fixedly connected to the sixth mold core. The fifth inclined guide hole and the fourth inclined top block are both inclined from top to bottom and gradually forward.

[0049] Based on the above technical solution: the above settings enable the fifth and sixth mold cores to demold synchronously with the first mold core when the first mold core moves upward to demold, thereby improving product processing efficiency.

[0050] A further solution: The first oblique guide mechanism includes:

[0051] At least one first inclined guide post is disposed on the first body and moves synchronously with the first body;

[0052] At least one first oblique guide hole is provided on the third mold core, and each first oblique guide post is slidably inserted into the corresponding first oblique guide hole; the first oblique guide post and the first oblique guide hole are both arranged to gradually tilt to the right from top to bottom.

[0053] Based on the above technical solution: by utilizing the inclined surface cooperation between the first inclined guide post and the first inclined guide hole, the upward movement of the first main body is directly converted into the rightward horizontal movement of the third mold core, thereby realizing the synchronous demolding of the first mold core and the third mold core.

[0054] A further embodiment: a limiting guide mechanism is provided between the third mold core and the second main body. The limiting guide mechanism includes a limiting guide groove provided on the second main body and a limiting guide block provided on the third mold core. The limiting guide block is slidably disposed in the limiting guide groove in the left-right direction.

[0055] Based on the above technical solution: the cooperation between the limiting guide groove and the limiting guide block provides left and right sliding limit for the third mold core, preventing it from deviating during the demolding process. Working in conjunction with the first guiding mechanism, the demolding action of the third mold core is more stable and reliable.

[0056] The beneficial effects of this utility model are as follows:

[0057] This invention, by setting up a first inclined guide mechanism, a second inclined guide mechanism, and a reset mechanism, all uniformly driven by a first main body, simultaneously transforms the single opening and closing motion of the mold body—for example, the mold opening action where the first mold core moves away from the second mold core—into a synchronous demolding movement of the third mold core along a first direction (e.g., to the right) and the fourth mold core along an opposite second direction (e.g., to the left). This allows for synchronous demolding of the first to fourth mold cores in different directions. This structure fundamentally solves the technical problem of uncoordinated movements and easy interference among multiple moving mold cores during demolding of products with multi-directional, deep undercut features. Simultaneously, through the optimized cooperation of the inclined guide mechanism and the reset mechanism, the smoothness, stability, and reliability of the movement of each mold core are ensured under demolding requirements with large-angle mold cores (e.g., tilt angles greater than 12 degrees), significantly improving the molding quality, demolding efficiency, and mold lifespan of complex structure products.

Detailed Implementation

[0076] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0077] like Figures 1 to 14 As shown, this embodiment provides a multi-directional linkage demolding mold, including:

[0078] The mold body 1 includes a first body 2 and a second body 5 that open and close relative to each other. The first body 2 is provided with a first mold core 3, and the second body 5 is provided with a second mold core 6. Specifically, the first body 2 and the first mold core 3 are moving molds, and the second body 5 and the second mold core 6 are fixed molds. A third mold core 14 is slidably provided on the second body 5. A fourth mold core 9 is slidably connected on the first body 2. The first mold core 3, the second mold core 6, the third mold core 14, and the fourth mold core 9 form a forming cavity for the product 4 when the mold is closed.

[0079] A first oblique guide mechanism is disposed between the third mold core 14 and the first body 2. The first oblique guide mechanism is used to convert the opening and closing movement of the first body 2 relative to the second body 5 into the movement of the third mold core 14 away from or towards the product 4.

[0080] A second oblique guide mechanism is disposed between the fourth mold core 9 and the first body 2. This second oblique guide mechanism is used to convert the opening and closing movement of the first body 2 relative to the second body 5 into movement of the fourth mold core 9 away from or towards the product 4; and...

[0081] A reset mechanism is used to drive the fourth mold core 9 to slide in the opposite direction to the product 4 relative to the mold opening direction of the first body 2.

[0082] When the mold is opened, an external force, such as a cylinder, drives the first body 2 and the first mold core 3 to move away from the second body 5 and the second mold core 6 to demold. The first body 2 drives the third mold core 14 to move along the first direction to demold through the first oblique guide mechanism. The first body 2 drives the fourth mold core 9 to move along the second direction opposite to the first direction to demold through the second oblique guide mechanism.

[0083] Specifically, the first mold core 3 and the second mold core 6 move in opposite directions to demold, and the third mold core 14 and the fourth mold core 9 move in opposite directions to demold, thereby achieving synchronous demolding.

[0084] In one specific embodiment, the first main body 2 opens and closes by moving relative to the second main body 5 in the vertical direction; the third mold core 14 is slidably disposed on the second main body 5 in the horizontal direction.

[0085] The first main body 2 drives the third mold core 14 to move to the right for demolding via the first oblique guide mechanism, and the first main body 2 drives the fourth mold core 9 to move to the left for demolding via the second oblique guide mechanism. The above-mentioned up-down and left-right directions can be converted to other directions according to specific needs, and this embodiment does not impose this limitation.

[0086] In one specific implementation, reference is made to... Figure 1 and Figure 2 As shown, since the ejection distance of the top plate assembly 21 relative to the first main body 2 is very small, only 30mm, the second inclined ejector block 8 needs a relatively large tilt angle (greater than or equal to 12 degrees) to achieve synchronous demolding of the fourth mold core 9. In order to ensure that the top plate assembly 21 can be ejected smoothly, thereby driving the fourth mold core 9 to move stably to the left for demolding, refer to... Figure 4 , Figure 7 , Figure 10 and Figure 13 As shown, the second inclined guide mechanism includes:

[0087] The second inclined ejector block 8, the upper end of which is slidably engaged with the reset mechanism, and the lower end of which is integrally formed or fixedly connected to the fourth mold core 9, preferably integrally formed; and...

[0088] The second inclined guide hole 31 is disposed on the first mold core 3, and the second inclined ejector block 8 is disposed through the second inclined guide hole 31. When the first mold core 3 moves upward to open the mold, the fourth mold core 9 will be driven to move to the left to demold through the cooperation of the second inclined guide hole 31 and the second inclined ejector block 8.

[0089] To further improve the stability of the fourth mold core 9 during demolding and to prevent the fourth mold core 9 from failing to demold smoothly during the first demolding action, the second inclined guide mechanism in this embodiment further includes:

[0090] The second inclined guide post 26 is disposed on the first main body 2; and,

[0091] The second inclined top seat 7 is disposed on the upper end of the second inclined top block 8 and is slidably connected to the reset mechanism in the left-right direction. The second inclined top seat 7 is provided with a third inclined guide hole 71 that cooperates with the second inclined guide post 26. The second inclined top seat 7 is provided with a second inclined guide groove 72. The second inclined guide groove 72 gradually slopes upward from right to left. The upper end of the second inclined top block 8 is slidably connected to the second inclined guide groove 72.

[0092] The second inclined guide post 26, the second inclined guide hole 31, the second inclined top block 8 and the third inclined guide hole 71 have the same inclination direction, and all of them gradually tilt from top to bottom and to the left.

[0093] During the first demolding step, the first main body 2 and the first mold core 3 move upwards simultaneously away from the second main body 5 and the second mold core 6. Simultaneously, the reset mechanism drives the second inclined ejector seat 7 and the second inclined ejector block 8 to move downwards relative to the first main body 2. Through the inclined engagement of the second inclined guide post 26 and the third inclined guide hole 71, the second inclined ejector seat 7 slides to the left. At the same time, through the inclined engagement of the second inclined ejector block 8 and the first mold core 3, the fourth mold core 9 slides to the left for demolding, thus achieving synchronous leftward movement of the second inclined ejector seat 7, the second inclined ejector block 8, and the fourth mold core 9. During this process, the second inclined ejector block 8 moves slightly from right to left along the second inclined guide groove 72, allowing the lower end of the fourth mold core 9 to be smoothly demolded from the product 4.

[0094] In one specific embodiment, the inclination angle of the second inclined guide post 26, the second inclined guide hole 31, the second inclined top block 8, and the third inclined guide hole 71 is 12-30 degrees, specifically 20 degrees.

[0095] In one specific implementation, such as Figure 4 , Figure 7 , Figure 8 and Figure 10 As shown, the reset mechanism includes:

[0096] A top plate assembly 21 is slidably disposed on the first main body 2 in the vertical direction. A second inclined top seat 7 is located below the top plate assembly 21 and is slidably connected to the top plate assembly 21 in the horizontal direction. The top plate assembly 21 specifically includes an upper top plate 211 and a lower top plate 212 fixedly connected together.

[0097] The elastic reset component 22 is used to drive the top plate component 21 to slide downward relative to the first body 2, and the second inclined top seat 7 is slidably disposed on the top plate component 21 in the left-right direction. Specifically, when the mold is opened, the first body 2 and the first mold core 3 move upward to demold. Since the top plate component 21 is slidably connected to the first body 2, the elastic reset component 22 will drive the top plate component 21 to move downward relative to the first body 2 under its own reset action (specifically, the top plate component 21 is stationary relative to the second body 5 in the up-down direction). At the same time, combined with the guiding action of the second inclined guide mechanism, the fourth mold core 9 can move stably to the left to demold.

[0098] In one specific implementation, such as Figure 4 , Figure 7 , Figure 8 and Figure 10 As shown, to facilitate the installation of the top plate assembly 21, the first main body 2 is provided with a first mounting cavity 23. The top plate assembly 21 is slidably disposed within the first mounting cavity 23 in the vertical direction. At least one first guide post 24 is fixedly provided on the top plate assembly 21, and the first main body 2 is provided with a first guide hole 25 that cooperates with the first guide post 24. Preferably, there are two first guide posts 24, located on the front and rear sides of the top plate assembly 21 respectively, and two corresponding first guide holes 25.

[0099] In order to make the top plate assembly 21 more stable in sliding up and down relative to the first body 2, the top plate assembly 21 is also provided with a number of second guide posts 215, and the first body 2 is provided with second guide holes 216 corresponding to the second guide posts 215.

[0100] The above configuration ensures that during the mold opening process, when the top plate assembly 21 slides downward relative to the first main body 2 and abuts against the lower bottom wall of the first mounting cavity 23, the first mold opening action is completed, meaning that the first mold core 3, the third mold core 14, and the fourth mold core 9 all disengage from the key undercut structure on the product 4. Afterwards, the first main body 2 and the first mold core 3 will, through the top plate assembly 21, the second inclined ejector 7, and the second inclined ejector block 8, simultaneously drive the fourth mold core 9 to move upward a certain distance, completing the second mold opening action and facilitating the user's subsequent removal of the product 4.

[0101] In one specific implementation, such as Figure 6 , Figure 7 , Figure 11 and Figure 12 As shown, the elastic reset component 22 includes:

[0102] At least one first return spring 221 is disposed between the upper side of the top plate assembly 21 and the upper top wall of the first mounting cavity 23; and / or,

[0103] At least one second return spring 222 is disposed between the limiting step in the corresponding first guide hole 25 and the limiting abutment at the lower end of the first guide post 24 and is sleeved on the first guide post 24.

[0104] In a preferred embodiment, the elastic reset assembly 22 includes two first reset springs 221 and two second reset springs 222. This ensures that when the first mold core 3 and the first body 2 move upwards to open the mold, the reset action of the first reset springs 221 and the second reset springs 222 prevents the fourth mold core 9 from being pulled upwards, thus allowing the fourth mold core 9 to always move stably to the left for demolding.

[0105] In one specific implementation, such as Figure 4 and Figure 7 As shown, the top plate assembly 21 is provided with:

[0106] The first clearance hole 213 is provided, and the second inclined guide post 26 is disposed through the first clearance hole 213, that is, during the mold opening process, the second inclined guide post 26 moves adaptively from right to left within the first clearance hole 213; and...

[0107] The first guide groove 214 is provided, and the second inclined ejector 7 is slidably disposed within the first guide groove 214 in the left-right direction. Under the action of the elastic reset component 22, the upper top wall of the first guide groove 214 abuts against the second inclined ejector 7. When the mold is opened, the second inclined ejector 7 moves from right to left along the first guide groove 214.

[0108] refer to Figure 1 , Figure 2 , Figure 7 , Figure 8 as well as Figure 12 As shown, the inner sides of the front and rear side walls of product 4 are provided with protruding structures. In order to achieve synchronous and smooth demolding, the mold for multi-directional linkage demolding in this embodiment also includes:

[0109] The fifth mold core 12 is located in front of the fourth mold core 9, and a third oblique guide mechanism is provided between the first main body 2 and the fifth mold core 12;

[0110] The sixth mold core 13 is located behind the fourth mold core 9, and a fourth oblique guide mechanism is provided between the first main body 2 and the sixth mold core 13;

[0111] When the mold is opened, the first body 2 and the first mold core 3 move upward away from the second body 5 and the second mold core 6 to demold. The first body 2 drives the fifth mold core 12 to move from front to back to demold through the third oblique guide mechanism. The first body 2 drives the sixth mold core 13 to move from back to front to demold through the fourth oblique guide mechanism.

[0112] As one specific implementation method, refer to Figure 1 , Figure 2 , Figure 7 , Figure 8 as well as Figure 12 As shown, the third oblique guide mechanism includes:

[0113] The fourth oblique guide hole 32 is disposed on the first mold core 3; and,

[0114] The third inclined top block 10 is inserted into the fourth inclined guide hole 32. The upper end of the third inclined top block 10 is slidably connected to the top plate assembly 21 in the left-right direction. Specifically, the top plate assembly 21 is provided with a third inclined top seat 17, and the upper end of the third inclined top block 10 is slidably connected to the third inclined top seat 17. The lower end of the third inclined top block 10 is integrally formed or fixedly connected to the fifth mold core 12. The fourth inclined guide hole 32 and the third inclined top block 10 are both inclined from top to bottom and gradually tilted backward.

[0115] The fourth oblique guide mechanism includes:

[0116] The fifth oblique guide hole 33 is disposed on the first mold core 3; and,

[0117] The fourth inclined top block 11 is inserted into the fifth inclined guide hole 33. The upper end of the fourth inclined top block 11 is slidably connected to the top plate assembly 21 in the left-right direction. Specifically, the top plate assembly 21 is provided with a fourth inclined top seat 18, and the upper end of the fourth inclined top block 11 is slidably connected to the fourth inclined top seat 18. The lower end of the fourth inclined top block 11 is integrally formed or fixedly connected to the sixth mold core 13. The fifth inclined guide hole 33 and the fourth inclined top block 11 are both inclined from top to bottom and gradually forward.

[0118] In one specific implementation, such as Figure 5 , Figure 13 and Figure 14 As shown, the first inclined guide mechanism includes:

[0119] At least one first inclined guide post 27 is disposed on the first body 2 and moves synchronously with the first body 2;

[0120] At least one first oblique guide hole 141 is disposed on the third mold core 14, and each first oblique guide post 27 is slidably inserted into its corresponding first oblique guide hole 141; the first oblique guide post 27 and the first oblique guide hole 141 are both arranged to gradually tilt to the right from top to bottom. When the mold is opened, as the first body 2 and the first mold core 3 move upward to demold, the third mold core 14 will be driven to move to the right relative to the second body 5 to demold through the cooperation of the first oblique guide post 27 and the first oblique guide hole 141.

[0121] Preferably, there are two first inclined guide posts 27, arranged side by side. Correspondingly, there are two first inclined guide holes 141, which respectively cooperate with the two first inclined guide posts 27.

[0122] In one specific implementation, such as Figure 14 and Figure 15 As shown, in order to ensure that the third mold core 14 can always slide stably along the second body 5 to achieve mold opening or closing, a limiting guide mechanism 16 is provided between the third mold core 14 and the second body 5. The limiting guide mechanism 16 includes a limiting guide groove 161 disposed on the second body 5 and a limiting guide block 162 disposed on the third mold core 14; the limiting guide block 162 is slidably disposed within the limiting guide groove 161 in the left-right direction. Specifically, the cooperation between the limiting guide groove 161 and the limiting guide block 162 provides left-right sliding limit for the third mold core 14, preventing it from deviating during demolding. Working in conjunction with the first guide mechanism, it makes the demolding action of the third mold core 14 more stable and reliable.

[0123] In one specific embodiment, in order to facilitate the movement of the first body 2 relative to the second body 5, the second body 5 is fixed on the worktable 15, and the first body 2 is movably disposed on the worktable 15 and can be raised and lowered relative to the first body 2.

[0124] Working principle explanation:

[0125] like Figure 3 , Figure 4 and Figure 8 As shown, in the mold-closed state, the first body 2 and the second body 5 are closed, and the first mold core 3 to the sixth mold core 13 together form the molding cavity of the product 4.

[0126] When the mold is opened, the first body 2 is driven by an external force to rise relative to the second body 5. During this process:

[0127] like Figures 9 to 12As shown, the first mold opening action is as follows: the first main body 2 rises, and the first inclined guide post 27 fixed on it rises accordingly. Through the inclined surface of the first inclined guide hole 141 on the third mold core 14, the third mold core 14 is directly driven to slide to the right on the second main body 5 for demolding. At the same time, since the top plate assembly 21 is elastically connected to the first main body 2 through the elastic reset assembly 22 (first reset spring 221 and / or second reset spring 222), at the initial moment of mold opening, the top plate assembly 21 maintains a lagging or downward movement trend relative to the first main body 2. This relative movement causes the second inclined top seat 7 to slide to the left within the first guide groove 214 of the top plate assembly 21, guided by the inclined surface of the second inclined guide post 26 fixed to the first main body 2 and its own third inclined guide hole 71. The leftward movement of the second inclined ejector 7, through the sliding engagement between its second inclined guide groove 72 and the upper end of the second inclined ejector block 8, and the guidance of the second inclined ejector block 8 passing through the second inclined guide hole 31 on the first mold core 3, jointly drives the fourth mold core 9, connected to the lower end of the second inclined ejector block 8, to slide stably to the left for demolding. The third inclined ejector block 10 and the fourth inclined ejector block 11, which are slidably connected to the top plate assembly 21, drive the fifth mold core 12 to slide backward and the sixth mold core 13 to slide forward for demolding, respectively, through the guidance of the fourth inclined guide hole 32 and the fifth inclined guide hole 33. At this point, all the laterally movable mold cores have simultaneously completed the crucial first step of demolding, separating from the undercut of the product 4.

[0128] Step 2: When the top plate assembly 21 moves downward until its lower surface contacts the bottom wall of the first mounting cavity 23, the first main body 2 continues to rise, which will drive the fourth mold core 9, the fifth mold core 12, and the sixth mold core 13 to rise synchronously as a whole through the top plate assembly 21, the second inclined top seat 7, and the second inclined top block 8, so as to facilitate the subsequent removal of the product 4.

[0129] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope of the claims of this utility model are within the protection scope of this utility model.
