Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0019] The inventors discovered through analysis of existing technologies that the ejection and sliding action of existing two-color injection molds are often synchronized or performed in a fixed sequence, which causes interference in the undercut or deep cavity areas during demolding, thereby forcibly pulling the product surface and causing scratches.

[0020] Reference Figure 1-3 This application illustrates a mold with a locking buckle and a synchronous demolding structure according to an embodiment of the present application; it includes a first molding module 100 and a second molding module 200; the first molding module 100 is connected to the second molding module 200; the first molding module 100 includes a front template 110, an injection template 120, and a locking buckle 130; the front template 110 is connected to the injection template 120; one end of the locking buckle 130 is connected to the front template 110, and the other end of the locking buckle 130 is connected to the injection template 120; the injection template 120 includes a first injection cavity 121 and an injection block 12. 2. A slider 123; the slider 123 is connected to the front template 110; one side of the injection block 122 is connected to the first injection cavity 121, and the other side of the injection block 122 is engaged with the slider 123; the injection block 122 is provided with a pulling part 1221, and the pulling part 1221 is connected to the mold locking buckle 130; when the mold is opened, the mold locking buckle 130 pushes open the front template 110 to move the slider 123 in the vertical direction, thereby unlocking the injection block 122, and the mold locking buckle 130 uses the pulling part 1221 to move the unlocked injection block 122 in the horizontal direction.

[0021] In the embodiments of this application, addressing the drawback of the fixed and singular mold opening and closing sequence in the prior art, this application provides a solution for controlling the timing of the slider 123 and the injection block 122 through the linkage of the locking buckle 130. Specifically, it includes a first molding module 100 and a second molding module 200; the first molding module 100 is connected to the second molding module 200; the first molding module 100 includes a front template 110, an injection template 120, and a locking buckle 130; the front template 110 is connected to the injection template 120; one end of the locking buckle 130 is connected to the front template 110, and the other end of the locking buckle 130 is connected to the injection template 120; The injection molding template 120 includes a first injection cavity 121, an injection block 122, and a slider 123; the slider 123 is connected to the front template 110; one side of the injection block 122 is connected to the first injection cavity 121, and the other side of the injection block 122 is engaged with the slider 123; the injection block 122 is provided with a pulling part 1221, which is connected to the mold locking buckle 130; when the mold is opened, the mold locking buckle 130 pushes open the front template 110, causing the slider 123 to move vertically, thereby unlocking the injection block 122; the mold locking buckle 130 then uses the pulling part 1221 to cause the unlocked injection block 122 to move horizontally. The front template 110 is pushed open by the locking buckle 130, causing the slider 123 to move vertically to unlock the injection block 122. Then, the injection block 122 is moved horizontally by the pulling part 1221. This solves the shortcomings of the existing technology, which has a fixed and single mold opening and closing sequence and is prone to tearing the product surface during demolding. It realizes the sequential separation of unlocking first and then demolding, thereby avoiding hard pulling and achieving the effect of protecting the product surface and improving the molding quality.

[0022] The following will further describe a mold having a locking buckle and a synchronous demolding structure in this exemplary embodiment.

[0023] It should be noted that the locking buckle 130 has the dual functions of linkage unlocking and horizontal core pulling. Its specific implementation principle is as follows: When the mold is opened, the locking buckle 130 first applies a pushing force to the front template 110, causing the front template 110 to separate from the injection template 120. This separation action drives the slider 123 connected to the front template 110 to move in the vertical direction, thereby disengaging the locking relationship between the slider 123 and the injection block 122, completing the unlocking of the injection block 122. Subsequently, through its connection with the pulling part 1221 on the injection block 122, the locking buckle 130 pulls out the injection block 122, which is already in a free state, in the horizontal direction during the continued mold opening process, so as to realize the demolding of the undercut or side hole of the product.

[0024] As an example, the snap-fit ​​method between slider 123 and injection block 122 can be the cooperation of inclined guide groove and roller, spring positioning ball and positioning hole, inclined wedge block, or sliding snap-fit ​​of T-shaped groove and T-shaped protrusion, etc.

[0025] In one specific implementation, the engagement between the slider 123 and the injection block 122 employs a T-shaped groove and a T-shaped protrusion. The injection block 122 has a T-shaped groove on its side, and a T-shaped protrusion of corresponding size is fixed on the slider 123. In the closed mold state, the T-shaped protrusion is embedded in the T-shaped groove, restricting the horizontal movement of the injection block 122. During mold opening, the front mold plate 110 moves upward, causing the slider 123 to move upward. The T-shaped protrusion slides out along the vertical direction of the T-shaped groove. When the protrusion is completely disengaged from the groove, the injection block 122 is unlocked. At this time, the mold locking buckle 130 pulls the injection block 122 out of the mold cavity horizontally via the pulling part 1221. By simultaneously driving the unlocking and horizontal demolding actions through the mold locking buckle 130, the mold opening sequence is strictly guaranteed. The mechanical linkage method has high reliability and avoids the risk of mold damage caused by electrical or hydraulic delays.

[0026] In one embodiment of this application, the second molding module 200 and the first molding module 100 are rotatably connected via a turntable 300; The second molding module 200 is provided with a second injection cavity 221; the first injection cavity 121 is used to mold a product of a first color; the second injection cavity 221 is used to mold a product of a second color; the turntable 300 is used to switch the product of the first color from the first injection cavity 121 to the second injection cavity 221.

[0027] It should be noted that the rotary connection of turntable 300 refers to the docking of the first molding module 100 and the second molding module 200 through a rotatable disc mechanism. The turntable 300 rotates around its central axis to rotate the product that has completed its first injection molding (first color) in the first injection cavity 121, along with its corresponding station, to the corresponding position in the second injection cavity 221 for a second injection molding (second color). This connection method must ensure that the product does not fall off during rotation, and that the two molding modules can tightly close the mold after rotation, realizing the process switching of two-color injection molding. The automatic station switching of two-color injection molding via turntable 300 eliminates the need for manual product handling, significantly improving production efficiency and automation. Simultaneously, the precise positioning of the rotary switching method effectively ensures the molding quality of the interface between the two-color products, reducing flash and misalignment defects.

[0028] In one embodiment of this application, the first molding module 100 further includes a rear template 140; the rear template 140 is connected to the injection molding template 120.

[0029] It should be noted that the rear template 140 refers to the template fixed to one side of the injection molding machine tail plate in the injection mold. It is connected to the injection template 120 and is used to support the mold core structure and transmit the clamping force of the injection molding machine.

[0030] Reference Figure 5 The diagram shows a schematic of the demolding structure 141 provided in one embodiment of this application. In one embodiment, the rear template 140 is provided with the demolding structure 141. The demolding structure 141 is connected to the first injection cavity 121. The first injection cavity 121 is provided with a first molding surface 1211 and a second molding surface 1212. The demolding structure 141 includes an inclined ejector 1411, a push block 1412, and a demolding drive component 1413. The inclined top 1411 is slidably connected to the first molding surface 1211, which is used to form the hard plastic part of the product; the push block 1412 is slidably connected to the second molding surface 1212, which is used to form the soft plastic part of the product. The demolding drive component 1413 is connected to the inclined ejector 1411 and the push block 1412. The demolding drive component 1413 is used to drive the inclined ejector 1411 and the push block 1412 to eject the product simultaneously.

[0031] It should be noted that the demolding drive component 1413 refers to the main power source or transmission structure used to provide ejection power and simultaneously drive the angled ejector 1411 and the push block 1412. Its core function is to establish the motion linkage between the angled ejector 1411 and the push block 1412, ensuring that their strokes are synchronized during demolding, thereby avoiding tearing or misalignment of the soft and hard plastic mating surfaces due to differences in action timing.

[0032] In one embodiment of this application, the inclined top 1411 forms an inclined angle with the first molding surface 1211, and the inclined angle ranges from 10 to 30°.

[0033] It should be noted that the tilt angle refers to the angle formed between the sliding guide direction of the tilting pin 1411 and the first forming surface 1211. This angle is the core parameter for the tilting pin 1411 mechanism to achieve the lateral core-pulling function. Its magnitude directly determines the distance of horizontal lateral displacement that the tilting pin 1411 can generate while performing vertical ejection movement. It also affects the bending stress and lateral friction force on the tilting pin 1411 rod. Optimizing the tilt angle range to 10~30° ensures sufficient lateral core-pulling distance for smooth release of the hard plastic part undercut while effectively controlling the lateral bending force on the tilting pin 1411 rod, avoiding pin jamming or excessive wear, extending the service life of the tilting pin 1411, and ensuring the smoothness and stability of the tilting pin 1411's reciprocating movement.

[0034] Reference Figure 4 The diagram shows a schematic of the structure of a locking buckle 130 provided in one embodiment of the present application. In one embodiment of the present application, the locking buckle 130 includes a locking seat 131 and a locking hook 132. The locking seat 131 is connected to the injection molding template 120. The locking hook 132 is disposed at both ends of the locking seat 131. The locking hook 132 includes a first locking hook 1321 and a second locking hook 1322; the first locking hook 1321 is connected to the front template 110, and the second locking hook 1322 is connected to the rear template 140.

[0035] It should be noted that the locking seat 131 is the base component of the locking buckle 130, fixed to the injection mold plate 120, and used to support and guide the movement of the locking hook 132. The first locking hook 1321 and the second locking hook 1322 are respectively located at both ends of the locking seat 131. The first locking hook 1321 extends towards the front mold plate 110 and connects to it, while the second locking hook 1322 extends towards the rear mold plate 140 and connects to it. The core function of this two-end arrangement is that during mold opening, the front mold plate 110 and the rear mold plate 140 move in opposite directions, and the two locking hooks 132 simultaneously slide outward within the locking seat 131, thereby achieving synchronous control of the bidirectional mold opening stroke. The locking seat 131 is made of wear-resistant tool steel and has internal guide channels to constrain the movement trajectory of the locking hooks 132.

[0036] As an example, the two locking hooks 132 can be horizontally opposite each other at the left and right ends of the locking seat 131; or they can be vertically opposite each other; or they can be arranged at a certain angle to adapt to the mold structure of asymmetrical mold opening; or even two parallel locking hooks 132 can be set at one end of the locking seat 131 and one at the other end to adapt to different force requirements.

[0037] In one specific implementation, two locking hooks 132 are positioned vertically opposite each other on a locking seat 131, which is a rectangular steel block fixedly installed at the center of the side of the injection molding template 120. A vertically extending straight guide groove, i.e., a hollow groove, is formed inside the locking seat 131, and this guide groove has a rectangular cross-section. The first locking hook 1321 is vertically inserted from the lower opening of the guide groove, with its first push-pull rod extending upwards along the guide groove and its first push-pull head extending out of the top of the guide groove, and is fixedly connected to the side of the front template 110 by bolts. The second locking hook 1322 is vertically inserted from the upper opening of the guide groove, with its second push-pull rod extending downwards along the guide groove and its second push-pull head extending out of the bottom of the guide groove, and is fixedly connected to the side of the rear template 140 by bolts. In the closed state, the two push-pull rods are positioned vertically opposite each other and close to each other in the guide groove. When the mold opens, the front mold plate 110 moves upward, causing the first push-pull rod to slide upward in the guide groove, while the rear mold plate 140 moves downward, causing the second push-pull rod to slide downward in the guide groove. The two push-pull rods separate vertically until their respective push-pull heads abut against the ends of the guide groove, thus limiting the mold opening stroke. The locking seat 131 is fixed to the side of the injection mold plate 120, and its position must ensure that the movement trajectories of the upper and lower push-pull rods are completely consistent with the movement directions of the front mold plate 110 and the rear mold plate 140, respectively. By placing the two locking hooks 132 vertically opposite each other, the movement direction of the locking hooks 132 is completely consistent with the mold opening direction, reducing force deflection loss, increasing transmission efficiency, and making the mold opening action more direct and stable. At the same time, this arrangement creates symmetrical force in the gravity direction of the front mold plate 110 and the rear mold plate 140, which helps to reduce the off-center load caused by gravity and improve the vertical accuracy of mold opening and closing.

[0038] In one embodiment of this application, the first locking hook 1321 includes a first push-pull rod and a first push-pull head; the first push-pull rod is connected to the first push-pull head; The first push-pull rod is connected to the locking seat 131, and the first push-pull head is connected to the front template 110.

[0039] It should be noted that the first push-pull rod and the first push-pull head together constitute the main structure of the first locking hook 1321. The first push-pull rod is a slender rectangular component, and its main body is slidably engaged with the locking seat 131, serving to guide and transmit the pushing and pulling force. The first push-pull head is located at the end of the first push-pull rod, that is, the end away from the locking seat 131, and is used to achieve a fixed connection with the front template 110.

[0040] In one embodiment of this application, the second locking hook 1322 includes a second push-pull rod and a second push-pull head; the second push-pull rod is connected to the second push-pull head; The second push-pull rod is connected to the locking seat 131, and the second push-pull head is connected to the rear template 140.

[0041] It should be noted that the second push-pull rod and the second push-pull head constitute the main structure of the second locking hook 1322, which is similar in principle to the first locking hook 1321 but in the opposite direction. The second push-pull rod is also a slender rectangular component that slides in conjunction with the locking seat 131; the second push-pull head is located at the end of the second push-pull rod, that is, the end away from the locking seat 131, and is used to fix it to the rear template 140.

[0042] In one embodiment of this application, the latch seat 131 is provided with a hollow groove, and the first push-pull rod and the second push-pull rod are both slidably connected to the hollow groove.

[0043] It should be noted that the hollow groove refers to a guide channel penetrating the interior of the locking seat 131. Its cross-sectional shape matches the shape of the push-pull rod, and it is used to constrain the first and second push-pull rods to slide linearly back and forth in a set direction. The hollow groove functions similarly to a guide sleeve, ensuring that the two push-pull rods remain coaxial during movement and preventing jamming or abnormal wear due to rod misalignment. The two push-pull rods are inserted from both ends of the hollow groove, forming a mating joint within the groove.

[0044] As an example, the cross-sectional shape of the hollow groove can be circular or square.

[0045] In one specific implementation, the hollow groove has a rectangular cross-section. A rectangular hollow groove is cut along the length of the center of the locking seat 131. During assembly, two push-pull rods are inserted from both ends of the hollow groove, leaving a gap between them in the middle of the groove. During mold opening, the front template 110 and the rear template 140 separate, and the two push-pull rods slide towards both ends within the hollow groove. The groove wall constrains the four sides of the push-pull rods, ensuring that they can only move linearly along the groove direction and cannot undergo radial offset or rotation. The sliding guidance of the two push-pull rods by the hollow groove ensures the linearity and accuracy of the movement of the locking buckle 130, effectively preventing the push-pull rods from bending or deflecting under force. At the same time, the rectangular cross-section fit also has an anti-rotation function, further improving the stability and consistency of the mold opening action and extending the service life of the locking buckle 130.

[0046] In one embodiment of this application, the injection block 122 is provided with a groove, and the slider 123 is provided with a protrusion, and the groove and the protrusion are engaged.

[0047] It should be noted that the groove and protrusion engagement refers to the separable connection between the injection block 122 and the slider 123 through a mechanical structure of concave-convex fit. In the mold-closed state, the protrusion is embedded in the groove, positioning the injection block 122 together with the slider 123 and bearing the injection pressure. During mold opening, when the slider 123 moves vertically, the protrusion disengages from the groove, releasing the constraint on the injection block 122, allowing it to be pulled horizontally by the mold locking buckle 130. This engagement is a dynamic fit, allowing free separation in one direction while forming a limit in another. The clearance fit accuracy of the engagement directly affects the smoothness of unlocking and the positioning accuracy during mold closing.

[0048] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device.
