Description
Technical Field
[0001] This invention belongs to the field of molds, and specifically relates to a structure and mold for separating the flow channel from the product. Background Technology
[0002] In mold production, the front mold often has an internal drawing structure, resulting in obvious step differences on the product surface, which makes it impossible to meet the requirements of the product's outer surface.
[0003] Currently, most existing molds have a different angle at the glue position than the ejection direction, and most of the driving components used to drive the molding block to detach or extend into the product cavity are in the same direction of movement as the molding block, which increases the overall space occupied by the mold. At the same time, during the molding process of the molding block and the locking process of the locking block, the cooperation between the two often causes positional interference, which affects the stability of the product when the molding block is molding, resulting in a reduction in the precision of the product after molding. Summary of the Invention
[0004] To address the aforementioned shortcomings of existing technologies, the technical problem to be solved by this invention is to propose a structure and mold for separating the flow channel from the product by placing the driving component along the mold opening direction, thereby saving the overall space occupied by the mold, and by utilizing the pull block and the support block and spring block in the reset component to ensure the smoothness of the successive movement of the forming block and the locking block during the mold opening and closing process, effectively preventing the forming block from retreating, which is stable, reliable, and conducive to improving product accuracy.
[0005] The technical solution adopted by the present invention to solve its technical problem is to propose a structure for separating the flow channel from the product, including: a molding block with a flow channel inside, the molding block being set at an angle to the mold opening direction, and the molding block being movably inserted into the product cavity to form the required product; A locking element is disposed on one side of the molding block. The locking element includes a locking block and a pulling block, both of which move along the inclined direction of the molding block. The locking block movably abuts against the side wall of the molding block to prevent the molding block from detaching from the product cavity. The pulling block can pull the molding block away from the product cavity along its inclined direction after the locking block moves away from the molding block, so as to separate the flow channel from the molded product. A driving component has a drive shaft connected to its output end. The moving direction of the drive shaft is consistent with the mold opening direction, and the drive shaft is movably engaged with the locking component to drive the locking block and the pulling block to move closer to or away from the forming block. A reset component is disposed on the same side as the locking component and the forming block. The reset component includes a support block and a spring block. The support block is fixed on the outer wall of the forming block and extends into the side wall of the locking component. The spring block is movably inserted into the locking component. The spring block can be compressed along the inside of the locking component when the mold is closed, and it abuts against the support block due to the movement of the locking component. After the forming block is reset and inserted into the product cavity, the spring block and the support block are misaligned to restrict the movement of the forming block by the locking block and the pull block.
[0006] In the above-mentioned structure for separating the flow channel from the product, a drive block is connected to the drive shaft, a moving block is inclinedly provided on the locking member, the locking block is connected to the end of the moving block, and the end of the moving block away from the locking block is movably engaged with the drive block, so that when the drive block moves along the mold opening direction, the moving block pushes the locking block to press against the molding block along its inclined direction.
[0007] In the above-mentioned structure for separating the flow channel from the product, the locking member is further provided with a self-locking slider. The self-locking slider is distributed on the upper and lower end faces of the locking block, and the side of the self-locking slider near the locking block is provided with an inclined engagement groove. The locking block is provided with an inclined engagement block, and the engagement block is movably engaged with the engagement groove.
[0008] In the above-mentioned structure for separating the flow channel from the product, the movable block is provided with a mounting groove, the mounting groove is perpendicular to the outer wall of the movable block, the spring block is movably inserted into the mounting groove, and an elastic element for moving and resetting the spring block is connected between the bottom of the mounting groove and the spring block.
[0009] In the above-mentioned structure for separating the flow channel from the product, the reset member further includes an L-shaped block fixed on the mold, the L-shaped block is provided with a first inclined surface, the spring block is provided with a second inclined surface, and the second inclined surface movably abuts against the first inclined surface; When the moving block moves the spring block closer to the molding block, the spring block retracts along the mounting groove due to the L-shaped block, and presses against and pushes the support block when the spring block moves and retracts, so that the molding block is inserted into the product cavity along its inclined direction.
[0010] In the above-mentioned structure for separating the flow channel from the product, the support block has a guide slope formed on the inner end near the spring block. The guide slope allows the spring block to be misaligned with the support block when it moves and retracts.
[0011] In the above-mentioned structure for separating the flow channel from the product, the mold is further provided with a fixed seat for mounting the driving component. The fixed seat is provided with a guide groove in the vertical direction. The driving block is provided with a guide block and an inclined traction block. The moving block is provided with an inclined traction groove at one end away from the locking block. The guide block is movably engaged in the guide groove, and the traction block is movably engaged in the traction groove, so that when the driving block moves in the mold opening direction, it drives the locking block to press against the molding block in its inclined direction.
[0012] In the above-mentioned structure for separating the flow channel from the product, the pull block and the forming block are inclined in the same direction. One end of the pull block is connected to the outer wall of the moving block by a fastener. The other end of the pull block forms an extension block. The outer wall of the forming block is provided with a guide groove in the same direction as its inclination. The extension block is movably engaged in the guide groove.
[0013] In the above-mentioned structure for separating the flow channel from the product, the molding block is provided with a limiting groove, and the end of the locking block is formed with a limiting block. The limiting block is movably inserted into the limiting groove to restrict the displacement of the locking block relative to the molding block.
[0014] The technical solution adopted by the present invention to solve its technical problem is to also propose a mold, including one of the above-mentioned structures for separating the flow channel from the product.
[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention provides a structure and mold for separating the runner from the product. By keeping the moving direction of the drive shaft of the drive component consistent with the mold opening direction, it is beneficial to save the overall space occupied by the mold. At the same time, during the mold opening process, the pull block is used to drive the molding block to separate from the product cavity along its inclined direction, so that the internal runner and the product's mold exit direction have a certain angle, realizing the separation of the product from the runner and effectively preventing obvious step differences on the product surface. During the mold closing process, the spring block and the support block are used to abut against each other to complete the molding block to be pre-pressed into the product cavity. The misalignment of the spring block and the support block makes the locking block press against the side wall of the molding block, which has a good anti-backward effect. The structure has good overall stability. During the product injection molding process, the locking component effectively solves the problem of the core pulling back phenomenon affecting the product molding quality, so that the precision of the molded product is relatively high.
[0016] (2) The elastic element between the mounting groove and the spring block is conducive to the compression and shrinkage by the L-shaped block during the mold closing process. In this way, the spring block pushes the support block during the shrinkage and movement process, so that the molding block is pre-inserted into the product cavity. After the spring block and the support block are misaligned, the locking block and the self-locking slider can be used to lock the molding block. The structure has good stability and is conducive to ensuring the product qualification rate.
[0017] (3) The guide slope on the support block makes it easier for the spring block to move in the process of pressing against and pushing the support block to achieve the movement of the forming block. The guide slope guides the spring block to descend and the support block to achieve misalignment, effectively preventing the two from interfering with each other due to processing errors. This completes the anti-retraction effect of the locking block and the self-locking slider on the forming block. Attached Figure Description

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0021] like Figure 1 As shown, this solution mainly focuses on the structure of separating the runner from the product. However, this structure of separating the runner from the product is not limited to the case of injection molds, but can also be applied to other places where it is needed, such as die casting molds and other molds.
[0022] like Figures 1 to 7 As shown, the present invention discloses a structure for separating the flow channel from the product, comprising: a molding block 1 with a flow channel internally configured, the molding block 1 being set at an angle to the mold opening direction, and the molding block 1 being movably inserted into the product cavity to form the desired product; a locking member 2, which is disposed on one side of the molding block 1, the locking member 2 including a locking block 20 and a pulling block 21 both moving along the inclined direction of the molding block 1, the locking block 20 being movably abutting against the side wall of the molding block 1 to prevent the molding block 1 from detaching from the product cavity; the pulling block 21 being able to pull the molding block 1 away from the product cavity along its inclined direction after the locking block 20 moves away from the molding block 1, thereby realizing the separation of the flow channel from the formed product; and a driving member 3, the output end of which is connected to a driving shaft 30, the driving shaft... The moving direction of drive shaft 30 is consistent with the mold opening direction, and drive shaft 30 is movably engaged with locking member 2 to drive locking block 20 and pull block 21 to move closer to or away from forming block 1; reset member 4 is provided on the same side of locking member 2 and forming block 1. Reset member 4 includes support block 40 and spring block 41. Support block 40 is fixed on the outer wall of forming block 1 and extends into the side wall of locking member 2. Spring block 41 is movably inserted into locking member 2. Spring block 41 can be compressed along the inside of locking member 2 when the mold is closed, and press against support block 40 due to the movement of locking member 2. After forming block 1 is reset and inserted into product cavity, spring block 41 and support block 40 are misaligned to realize that locking block 20 and pull block 21 restrict the movement of forming block 1.
[0023] In this embodiment, the direction of movement of the drive shaft 30 of the drive component 3 is consistent with the direction of mold opening, instead of the traditional method where the drive component 3 and the molding block 1 are on the same straight line. This helps to save space in the entire mold. After the product injection molding is completed in this solution, the drive component 3 moves along... Figure 1When moving vertically, the locking block 20 in the locking component 2 moves away from the molding block 1, and after a certain distance, the pulling block 21 pulls the molding block 1 out of the product cavity along its inclined direction before the mold opening action is performed. That is, the molding block 1 needs to be pulled out before the mold opens because the molding block 1 contains a runner for injection molding. In common front mold in-mold structures, the product surface has obvious steps. Therefore, this solution pre-separates the runner from the product during the core-pulling process of the molding block 1 before the mold opens, ensuring that the product is not affected by the runner during the mold opening process, thus guaranteeing product quality. Similarly, during the mold closing and injection molding process, due to… Most of the glue position differs from the mold exit angle, resulting in significant injection pressure during injection molding. Since most of the glue position is located in the internal extraction structure, it is prone to core-pulling backward movement. This solution addresses this by having the spring block 41 retract and move, pressing against the support block 40 during mold closing. The movement of the support block 40 causes the molding block 1 to be pre-inserted into the product cavity. Once the spring block 41 and support block 40 are misaligned, the locking element 2, during its continued movement, can press against the side wall of the molding block 1 using the locking block 20, effectively preventing the molding block 1 from retracting. This structure offers good overall stability and, while maintaining relatively high precision, effectively ensures a high product qualification rate.
[0024] A drive block 31 is connected to the drive shaft 30, and a moving block 22 is inclinedly provided on the locking member 2. The locking block 20 is connected to the end of the moving block 22, and the end of the moving block 22 away from the locking block 20 is movably engaged with the drive block 31, so that when the drive block 31 moves along the mold opening direction, the moving block 22 pushes the locking block 20 to press against the molding block 1 along its inclined direction.
[0025] like Figures 1 to 2 As shown, both the drive shaft 30 and the drive block 31 are arranged vertically (i.e., the mold opening direction). The moving block 22 on the locking member 2 is aligned with the tilt direction of the forming block 1. Since the moving block 22 is movably engaged with the drive block 31 connected to the drive shaft 30, the drive member 3 drives the drive block 31 along the vertical direction. Figure 2 When moving vertically, it can push the moving block 22 to move along its tilt direction, and finally the moving block 22 drives the locking block 20 at the end to press against or move away from the molding block 1. This effectively prevents the molding block 1 from shifting during the injection molding process in the product cavity, improving stability and ensuring that the quality of the molded workpiece is not affected.
[0026] The mold is also provided with a fixed seat 5 for mounting the driving component 3. The fixed seat 5 is provided with a guide groove 50 in the vertical direction. The driving block 31 is provided with a guide block 310 and an inclined traction block 311. The moving block 22 is provided with an inclined traction groove 220 at one end away from the locking block 20. The guide block 310 is movably engaged in the guide groove 50, and the traction block 311 is movably engaged in the traction groove 220, so that when the driving block 31 moves in the mold opening direction, it drives the locking block 20 to press against the forming block 1 in its inclined direction.
[0027] like Figure 2 As shown, the fixing seat 5 on the mold is mainly used to fix the driving component 3 in the vertical direction. The guide block 310 on the driving block 31 is movably engaged in the guide groove 50 of the fixing seat 5, so that the driving block 31 can always move along the vertical direction under the drive of the driving component 3. Figure 2 The vertical reciprocating motion, and because the inclined traction block 311 on the drive block 31 is also engaged in the inclined traction groove 220, when the drive block 31 moves vertically along the direction of the guide groove 50, the traction block 311 moves along the length direction of the traction groove 220, and the moving block 22 pushes the locking block 20 to press against or move away from the molding block 1 along their common inclined direction. This structure saves the overall space occupied by the locking part 2 while ensuring the smoothness of each structure during the movement process, thereby improving the stability of the molded product.
[0028] The locking component 2 is also provided with a self-locking slider 23. The self-locking slider 23 is distributed on the upper and lower end faces of the locking block 20. The side of the self-locking slider 23 near the locking block 20 is provided with an inclined engagement groove 230. The locking block 20 is provided with an inclined engagement block 200, which is engaged with the engagement groove 230.
[0029] Because of the high injection pressure during injection molding, this design includes a self-locking slider 23 at both the upper and lower ends of the locking block 20. Figures 2 to 3 As shown, the surfaces in contact with the self-locking slider 23 and the locking block 20 are both inclined surfaces. The locking groove 230 formed on the self-locking slider 23 is used to engage with the inclined locking block 200 on the locking block 20, which helps to prevent the locking block 20 from shifting when it is pressed against the molding block 1, and effectively avoids the molding block 1 from dislodging when the product is injected into the mold.
[0030] Furthermore, such as Figure 2As shown, a protrusion 231 is formed on the side of the self-locking slider 23 away from the locking block 20. A locking groove 6 is provided in the moving and fixed mold cavities. During the mold closing process, as the moving block 22 pushes the locking block 20 closer to the forming block 1, the self-locking slider 23 moves synchronously towards the forming block 1 and presses against it due to the movable engagement of the locking block 200 and the locking groove 230. At this time, the mold is completing the mold closing action. Figure 2 The protrusion 231 is stably inserted into the locking groove 6 during the movement to form a fit, which further improves the anti-backflow effect of the molding block 1 inserted into the product cavity and enhances the stability of the structure during injection molding.
[0031] The pull block 21 is inclined in the same direction as the forming block 1. One end of the pull block 21 is connected to the outer wall of the moving block 22 by a fastener. The other end of the pull block 21 forms an extension block 210. The outer wall of the forming block 1 is provided with a guide groove 10 in the same direction as its inclination. The extension block 210 is movably engaged in the guide groove 10.
[0032] like Figure 2 and Figure 4 As shown, after the product is injection molded, the drive block 31 moves away from the locking block 20 via the moving block 22 during the movement process. During this movement, the self-locking slider 23 moves away from the molding block 1 simultaneously. During this process, the reset member 4 does not apply a pulling force to the molding block 1 to disengage it from the product cavity, and the extension block 210 on the pull block 21 moves away from its original position as the moving block 22 moves. Figure 4 The rightmost end of the guide groove 10 slides to the leftmost end of the guide groove 10, and the driving block 31 continues to drive the moving block 22 along... Figure 4 When tilting to the left, the force on the inner wall of the leftmost end of the guide groove 10 can be applied through the extension block 210, thereby driving the molding block 1 to leave the product cavity along its tilting direction. The purpose of this design is to enable the mold to achieve the sequential action of locking the block 20 being unlocked before the molding block 1 is pulled out of the product cavity. The two can achieve mutual function without interference during displacement, making the structure more stable and reliable during operation.
[0033] The movable block 22 is provided with a mounting groove 221, which is perpendicular to the outer wall of the movable block 22. The spring block 41 is movably inserted into the mounting groove 221, and an elastic element for moving and resetting the spring block 41 is connected between the bottom of the mounting groove 221 and the spring block 41.
[0034] Regarding the elastic contraction of the aforementioned spring block 41, such as Figures 4 to 6As shown, the spring block 41 is movably inserted into the mounting groove 221. The elastic element (not shown in the figure) between the mounting groove 221 and the spring block 41 provides the ability for the spring block 41 to retract and move. The mounting groove 221 restricts the direction of movement of the spring block 41 when it retracts, ensuring that the spring block 41 pushes the support block 40 to insert the molding block 1 into the product cavity during the process of retracting and moving with the moving block 22. After the spring block 41 and the support block 40 are misaligned, the moving block 22 locks the molding block 1 that has been inserted into the product cavity by driving the locking block 20. In addition, the locking groove 6 of the self-locking slider 23 inserted into the moving and fixed mold cavities further improves the anti-retraction effect of the molding block 1 during the product injection molding process, which is conducive to improving the stability of the structure. It should be noted that the elastic element mentioned in the text can be a compression spring, a return spring, or other elastic elements.
[0035] The reset component 4 also includes an L-shaped block 42 fixed on the mold. The L-shaped block 42 is provided with a first inclined surface 420, and the spring block 41 is provided with a second inclined surface 410. The second inclined surface 410 moves against the first inclined surface 420. When the moving block 22 drives the spring block 41 to approach the molding block 1, the spring block 41 shrinks along the mounting groove 221 due to the L-shaped block 42. When the spring block 41 moves and shrinks, it presses against and pushes the support block 40, so as to realize that the molding block 1 is inserted into the product cavity along its inclined direction.
[0036] like Figure 1 , Figures 4 to 7 As shown, the L-shaped block 42 on the reset piece 4 is fixed on the fixed mold and does not produce relative displacement. Since the spring block 41 is set in the mounting groove 221 of the moving block 22, it should be noted that the spring block 41 was originally positioned on one side of the L-shaped block 42, extending out of the mounting groove 221. Therefore, when the moving block 22 moves the spring block 41 closer to the forming block 1 in the inclined direction, the spring block 41 can shrink along the mounting groove 221 during the movement due to the pressure of the L-shaped block 42 located on the side wall of the moving block 22. This is mainly due to... Figure 6 The second inclined surface 410 on the shown spring block 41 and Figure 5 When the first inclined surfaces 420 on the L-shaped blocks 42 abut against each other, the spring block 41 gradually compresses and contracts into the mounting groove 221 along the first inclined surface 420 as it continues to move towards the forming block 1. At the same time... Figure 5 The state shown indicates that the spring block 41 is about to connect with the support block 40. Figure 7 The aforementioned misaligned setting state, in Figure 5 Before the state shown, that is, during the process of the second inclined surface 410 abutting against the first inclined surface 420, the end of the spring block 41 will abut against... Figure 4On the left end of the support block 40, while the spring block 41 slides along the first inclined surface 420, it can also push the support block 40 to allow the molding block 1 to move along its inclined direction and be inserted into the product cavity. It should be noted that during the process of the spring block 41 pushing the support block 40 to move, the moving block 22 also simultaneously pushes the locking block 20 and the self-locking slider 23 to move closer to the side wall of the molding block 1. Therefore, when the spring block 41 moves with the moving block 22 and moves with the support block 40, it achieves... Figure 7 When the misalignment is shown, the molding block 1 is inserted into the product cavity, and the locking block 20 and the self-locking slider 23 can also press against the side wall of the molding block 1 to achieve the required anti-retraction effect. It can be seen that when the mold opens, the spring block 41 and the support block 40 will not exert a moving force. The movement of the molding block 1 is mainly achieved by the pull plate, which moves it away from the product cavity along the guide groove 10. Therefore, only when the mold is closed can the spring block 41, the support block 40 and the L-shaped block 42 drive the molding block 1 to be inserted into the product cavity, so as to achieve the connection action of the molding block 1 first being inserted into the product cavity and the locking block 20 and the self-locking slider 23 locking it afterward. The two do not interfere with each other, which improves the stability of the molding block 1 when the mold is injection molding the product, and ensures the production efficiency of the mold and the qualification rate of the product.
[0037] The inner end of the support block 40 near the spring block 41 has a guide slope 400, which allows the spring block 41 to be misaligned with the support block 40 when it moves and retracts.
[0038] like Figure 6 As shown, machining errors are inevitable during the mold manufacturing process. In this embodiment, a guide slope 400 is formed at the inner end of the support block 40 near the spring block 41. Even if there is a slight machining error on the side of the spring block 41 that is in contact with the support block 40, the guide slope 400 can guide the spring block 41 along the misalignment direction as it moves with the moving block 22, thereby ensuring that the spring block 41 and the support block 40 achieve the desired fit. Figure 7 The misalignment shown in the diagram, while achieving the above functions, also effectively prevents the spring block 41 from getting stuck between it and the support block 40 due to positional interference when it retracts and moves. The smooth misalignment between the two also ensures that after the molding block 1 is inserted into the product cavity, the moving block 22 can smoothly drive the locking block 20 and the self-locking slider 23 to lock the molding block 1, further improving the smoothness of the connection between the various structures during movement, making the whole stable and reliable, and ensuring the product qualification rate.
[0039] The molding block 1 is provided with a limiting groove 11, and the end of the locking block 20 is formed with a limiting block 201. The limiting block 201 is movably inserted into the limiting groove 11 to limit the displacement of the locking block 20 relative to the molding block 1.
[0040] like Figure 2 As shown, by providing a limiting groove 11 on the side of the molding block 1 near the locking block 20, during the mold closing process, the limiting block 201 at the end of the locking block 20 is inserted into the limiting groove 11 of the molding block 1. The locking block 20 prevents the molding block 1 from detaching from the product cavity along its tilt direction, while the cooperation between the limiting block 201 and the limiting groove 11 effectively prevents the molding block 1 from moving along its tilt direction. Figure 2 The forward and backward displacement improves the stability of the mold's various structures during injection molding, ensuring that product quality is not affected.

The molding block is set at an angle to the mold opening direction and is movably inserted into the product cavity to form the required product. A locking element is disposed on one side of the molding block. The locking element includes a locking block and a pulling block, both of which move along the inclined direction of the molding block. The locking block movably abuts against the side wall of the molding block to prevent the molding block from detaching from the product cavity. The pulling block can pull the molding block away from the product cavity along its inclined direction after the locking block moves away from the molding block, so as to separate the flow channel from the molded product. A driving component has a drive shaft connected to its output end. The moving direction of the drive shaft is consistent with the mold opening direction, and the drive shaft is movably engaged with the locking component to drive the locking block and the pulling block to move closer to or away from the forming block. A reset component is disposed on the same side as the locking component and the forming block. The reset component includes a support block and a spring block. The support block is fixed on the outer wall of the forming block and extends into the side wall of the locking component. The spring block is movably inserted into the locking component. The spring block can be compressed along the inside of the locking component when the mold is closed, and abuts against the support block due to the movement of the locking component. After the forming block is reset and inserted into the product cavity, the spring block and the support block are misaligned to restrict the movement of the forming block by the locking block and the pull block. A drive block is connected to the drive shaft, and a moving block is inclinedly provided on the locking member. The locking block is connected to the end of the moving block, and the end of the moving block away from the locking block is movably engaged with the drive block, so that when the drive block moves along the mold closing direction, the moving block pushes the locking block to press against the molding block along its inclined direction. The movable block is provided with a mounting groove, which is perpendicular to the outer wall of the movable block. The spring block is movably inserted into the mounting groove, and an elastic element for the spring block to move and reset is connected between the bottom of the mounting groove and the spring block. The reset component also includes an L-shaped block fixed on the mold, the L-shaped block having a first inclined surface and the spring block having a second inclined surface, the second inclined surface being movably abutting against the first inclined surface; When the moving block moves the spring block closer to the molding block, the spring block retracts along the mounting groove due to the L-shaped block, and presses against and pushes the support block when the spring block moves and retracts, so that the molding block is inserted into the product cavity along its inclined direction.
2. The structure for separating the flow channel from the product according to claim 1, characterized in that, The locking component is also provided with a self-locking slider, which is distributed on the upper and lower end faces of the locking block. The side of the self-locking slider closest to the locking block is provided with an engagement groove at an angle. The locking block is provided with an engagement block at an angle, and the engagement block is movably engaged with the engagement groove.
3. The structure for separating the flow channel from the product according to claim 1, characterized in that, The support block has a guide slope at its inner end near the spring block, which allows the spring block to be misaligned with the support block when it moves and retracts.
4. The structure for separating the flow channel from the product according to claim 1, characterized in that, The mold is also provided with a fixed seat for mounting the driving component. The fixed seat is provided with a guide groove in the vertical direction. The driving block is provided with a guide block and an inclined traction block. The moving block is provided with an inclined traction groove at one end away from the locking block. The guide block is movably engaged in the guide groove, and the traction block is movably engaged in the traction groove, so that when the driving block moves in the mold closing direction, it drives the locking block to press against the forming block in its inclined direction.
5. A structure for separating the flow channel from the product according to claim 1, characterized in that, The pull block and the forming block are inclined in the same direction. One end of the pull block is connected to the outer wall of the moving block by a fastener. The other end of the pull block forms an extension block. The outer wall of the forming block is provided with a guide groove in the same direction as its inclination. The extension block is movably engaged in the guide groove.
6. A structure for separating the flow channel from the product according to claim 1, characterized in that, The molding block is provided with a limiting groove, and the end of the locking block is formed with a limiting block. The limiting block is movably inserted into the limiting groove to restrict the displacement of the locking block relative to the molding block.
