Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a sliding position inclined top delayed action mechanism and a mold for forming an undercut position product. Background Art

[0002] In the field of injection mold design, for plastic products with complex structural features, especially those with undercuts in the slide mold opening direction, traditional mold structures often face demoulding difficulties. To solve this problem, the slide slant top structure came into being. As an innovative mold design solution, it cleverly achieves effective demoulding of undercuts in the slide mold opening direction through integrated design.

[0003] Specifically, the core of the slide lifter structure lies in the clever addition of an ejector plate group inside the slide, and the ejector seat is firmly installed on the ejector plate group. In the initial stage of mold opening, in order to achieve effective demoulding of the ejector, the ejector plate group is designed to have a delayed action, that is, it does not move synchronously with the slide immediately, forcing the ejector to perform a reverse relative movement in the slide insert until the ejector is completely separated from the buckle surface of the plastic product. Subsequently, the ejector plate group moves synchronously with the slide body to complete the entire demoulding process.

[0004] The delayed action of the ejector plate group is achieved by setting a delay mechanism, but the design of the traditional delay mechanism has obvious shortcomings. The traditional design is to set a delay mechanism in the pressure strips on both sides of the slide to control the action sequence of the ejector plate group, but this design method may cause uneven force on both sides of the ejector plate group, thereby affecting the smoothness of its action, and ultimately may have an adverse effect on the injection molding production efficiency and product quality of the mold. Utility Model Content

[0033] See also Figures 1 to 4 The embodiment of the utility model discloses a sliding position inclined ejection delay action mechanism, which includes: a bottom plate 1; a sliding position assembly 2, the sliding position assembly 2 is slidably connected to the bottom plate 1 along a first direction, and a travel cavity 23 is arranged in the sliding position assembly 2; an ejector plate group 3, the ejector plate group 3 is slidably connected to the travel cavity 23 along the first direction; a delay mechanism 4, the delay mechanism 4 is arranged on one side of the bottom plate 1 along the first direction; wherein, a first connecting rod 31 is arranged between the ejector plate group 3 and the delay mechanism 4, one end of the first connecting rod 31 is connected to the center position of the ejector plate group 3, and the other end is slidably arranged in the delay mechanism 4, and the delay mechanism 4 is used to limit or release the sliding of the first connecting rod 31. It can be understood that the delay mechanism 4 limits or releases the sliding of the first connecting rod 31, thereby controlling the motion state of the ejector plate group 3. In a feasible mold opening process, the slide assembly 2 slides toward the delay mechanism 4 along the first direction, but due to the limiting effect of the delay mechanism 4, the ejector plate group 3 remains stationary, so that the ejector plate group 3 slides in the stroke cavity 23, and the slide assembly 2 and the ejector plate group 3 undergo relative displacement.

[0034] Furthermore, a second connecting rod 24 is provided between the sliding assembly 2 and the delay mechanism 4, one end of the second connecting rod 24 is fixed to the sliding assembly 2, and the other end is slidably penetrated into the delay mechanism 4; the second connecting rod 24 includes a trigger section 242 close to the sliding assembly 2 and a sliding section 241 close to the delay mechanism 4, when the sliding section 241 is penetrated into the delay mechanism 4, the delay mechanism 4 limits the sliding of the first connecting rod 31 so that the ejector plate group 3 and the bottom plate 1 are relatively stationary; when the trigger section 242 is penetrated into the delay mechanism 4, the delay mechanism 4 releases the limit on the sliding of the first connecting rod 31 so that the ejector plate group 3 and the sliding assembly 2 move synchronously. It should be explained that the working process of the slider tilting delay action mechanism of this embodiment may include the following action stages: 1. Initial stage: the mold is in the mold closing state, and the ejector plate group 3 is located at the initial position in the stroke cavity 23. At this time, the sliding section 241 of the second connecting rod 24 is inserted into the delay mechanism 4, and the delay mechanism 4 limits the first connecting rod 31, and the ejector plate group 3 and the bottom plate 1 are relatively stationary; 2. First mold opening stage: when the mold starts to open, the slider assembly 2 slides toward the delay mechanism 4 along the first direction. As the slider assembly 2 slides, the triggering section 242 of the second connecting rod 24 gradually approaches the delay mechanism 4. During this process, the ejector plate group 3 and the slider assembly 2 are relatively displaced; 3. Second mold opening stage: when the triggering section 242 of the second connecting rod 24 is inserted into the delay mechanism 4, the unlocking mechanism inside the delay mechanism 4 is triggered, the limit of the first connecting rod 31 is released, and the ejector plate group 3 is driven by the slider assembly 2 to slide synchronously along the first direction to complete the demoulding process.

[0035] Specifically, the delay mechanism 4 includes: a support plate frame 41, a stopper 42, and a top connecting member 43. The support plate frame 41 is provided with a first through hole, a second through hole, and a slot. The slot at least partially overlaps with the first through hole. The first connecting rod 31 is penetrated in the delay mechanism 4 through the first through hole. The second connecting rod 24 is penetrated in the delay mechanism 4 through the second through hole. The stopper 42 is installed in the slot. One end of the top connecting member 43 is connected to the stopper 42, and the other end abuts against the second connecting rod 24. When the sliding section 241 abuts against the top connecting member 43, the stopper 42 is located in the slot and fills the overlapping part of the first through hole and the slot. The other end of the first connecting rod 31 abuts against the stopper 42 to limit the sliding of the first connecting rod 31. When the triggering section 242 abuts against the top connecting member 43, the stopper 42 at least partially disengages from the slot and vacates the overlapping part of the first through hole and the slot to release the sliding limit of the first connecting rod 31. This embodiment achieves precise control of the sliding state of the first connecting rod 31 through the interaction between the second connecting rod 24 and the top connecting member 43 in the delay mechanism 4, and the movement of the stopper 42 in the slot. When the sliding section 241 or the trigger section 242 of the second connecting rod 24 contacts the top connecting member 43, it triggers the position change of the stopper 42, thereby changing the sliding limit state of the first connecting rod 31. It needs to be explained that with the opening action of the mold, the slide assembly 2 starts to slide, driving the second connecting rod 24 to move together. When the sliding section 241 continues to abut against the top connecting member 43, the stopper 42 remains motionless in the slot, and the sliding of the first connecting rod 31 is still limited. During this period of time, the slide assembly 2 and the ejector plate group 3 undergo relative displacement; with the further sliding of the slide assembly 2, the triggering section 242 of the second connecting rod 24 gradually approaches and finally abuts against the top connecting member 43. During this process, the top connecting member 43 applies a force to the stopper 42 to disengage it from the slot. When the triggering section 242 completely abuts against the top connecting member 43, the stopper 42 at least partially disengages from the slot and leaves the overlapping part of the first perforation and the slot vacant, thereby releasing the sliding limit on the first connecting rod 31. Once the sliding limit of the first connecting rod 31 is released, the ejector plate group 3 will move synchronously driven by the slide assembly 2 to complete the demoulding process.

[0036] Specifically, the extension height of the trigger section 242 toward the top connecting member 43 is greater than the extension height of the sliding section 241 beyond the top connecting member 43 , so the top connecting member 43 will be lifted up when it abuts against the trigger section 242 , thereby pushing the stopper 42 out of the slot.

[0037] Furthermore, the second connecting rod 24 further includes a guide section 243 connected between the sliding section 241 and the trigger section 242, and the side of the guide section 243 facing the top connecting member 43 is an inclined surface, and the inclined surface gradually approaches the top connecting member 43 from the sliding section 241 toward the trigger section 242. It can be understood that the inclined surface design of the guide section 243 is similar to the inclined wedge mechanism, which can provide a gradually changing guiding force during the movement of the second connecting rod 24, so that the second connecting rod 24 can smoothly transition from the sliding section 241 to the trigger section 242, and smoothly trigger the movement of the stopper 42 in the delay mechanism 4.

[0038] Furthermore, the delay mechanism 4 also includes an elastic member 423, a sliding hole is provided on the stopper 42, a connecting member 422 is slidably penetrated in the sliding hole, one end of the connecting member 422 passes through the sliding hole and is fixed to the card slot, and the elastic member 423 is connected between the other end of the connecting member 422 and the stopper 42, and is used to provide elastic force for the stopper 42 to move in the direction of the card slot. It can be understood that as the mold is opened, the slide assembly 2 drives the second connecting rod 24 to move, and when the trigger section 242 abuts against the top connecting member 43, the top connecting member 43 applies a force to the stopper 42 to make it disengage from the card slot. Since this force is greater than the elastic force of the elastic member 423, the stopper 42 begins to move and at least partially disengages from the card slot, thereby releasing the sliding limit of the first connecting rod 31. Once the sliding limit of the first connecting rod 31 is released, the ejector plate group 3 and the slide assembly 2 move synchronously to complete the demoulding process. As the slide assembly 2 is reset to the film closing state, the top connecting member 43 abuts against the sliding section 241 again. Under the elastic force of the elastic member 423, the stopper 42 moves toward the slot and resets. As the stopper 42 is reset, the overlapping part of the first perforation and the slot is filled again, preparing for the next delay action.

[0039] Specifically, the ejector plate group 3 has two extreme positions in the first direction in the stroke chamber 23, which are the first extreme position close to the delay mechanism 4 and the second extreme position away from the delay mechanism 4. When the trigger section 242 abuts against the top connecting member 43, the ejector plate group 3 is located at the second extreme position. This embodiment limits the movement range of the ejector plate group 3 in the stroke chamber 23 by designing the stroke chamber 23 and determining the two extreme positions of the ejector plate group 3. When the trigger section 242 abuts against the top connecting member 43, this state is used as a basis for judging whether the ejector plate group 3 has reached the second extreme position. When the ejector plate group 3 reaches the second extreme position, it will be driven by the slide assembly 2 to move synchronously.

[0040] Specifically, the length from the first limit position to the second limit position is equal to the distance from the abutment position between the sliding section 241 and the top connecting member 43 to the trigger section 242 when the ejector plate assembly 3 is at the first limit position, thereby avoiding motion interference or misalignment caused by displacement mismatch. In a feasible working process, when the mold is in the mold closing state, the ejector plate group 3 is located at the first extreme position, at which time the sliding section 241 of the second connecting rod 24 contacts the top connecting member 43; as the mold is opened, the slide assembly 2 begins to slide, driving the second connecting rod 24 to move together, the sliding section 241 continues to contact the top connecting member 43, and gradually approaches the triggering section 242 as the slide assembly 2 slides, until the triggering section 242 begins to contact the top connecting member 43. Since the length from the first extreme position to the second extreme position is equal to the distance from the contact position between the sliding section 241 and the top connecting member 43 to the triggering section 242 in the mold closing state, the contact of the triggering section 242 will immediately cause the delay mechanism 4 to be triggered, and the block 42 moves and releases the sliding limit on the first connecting rod 31. At the same time, the ejector plate group 3 is already in the second extreme position, so the ejector plate group 3 will be pushed by the slide assembly 2 and slide synchronously with the slide assembly 2 along the first direction.

[0041] Furthermore, the slide assembly 2 includes a slide seat 21 and a slide insert 22 , and a travel cavity 23 is formed between the slide seat 21 and the slide insert 22 .

[0042] Furthermore, a driving mechanism is included, and the driving mechanism is used to drive the slide assembly 2 to move along the first direction. Optionally, the driving mechanism is an oil cylinder, which is connected to the slide seat 21 of the slide assembly 2 through a pull rod.

[0043] An embodiment of the utility model also provides a mold for molding an inverted buckle product, including a slider inclined ejector delayed action mechanism as described above, and also including: a rear mold 5, which is arranged on the bottom plate 1; a front mold 6, which is detachably connected to the upper side of the rear mold 5; wherein the slider assembly 2 is arranged on the side of the rear mold 5, and when the rear mold 5, the front mold 6, and the slider assembly 2 are fitted together, a molding cavity is formed on the fitting side; an inclined hole is provided on the slider assembly 2, which is connected to the stroke cavity 23 and the molding cavity, and an inclined ejector rod 71 is passed through the inclined hole, and an inclined ejector seat 7 is connected to the ejector plate group 3 on the side facing the inclined hole, one end of the inclined ejector rod 71 is slidably connected to the inclined ejector seat 7, and the other end of the inclined ejector rod 71 is connected to a buckle slot 711, and the buckle slot 711 is used for the inverted buckle of injection-molded products.

[0044] It is understandable that the rear mold 5 fits with the front mold 6 to form a closed molding cavity. The injection molding machine injects the molten plastic into the molding cavity, and forms a product by cooling and solidifying. At this time, the buckle slot 711 is located in the molding cavity, contacts the molten plastic and molds the undercut part of the product. After the injection molding is completed, the mold starts to open the mold. At this time, the slider assembly 2 starts to move, and the ejector plate group 3 is stationary due to the action of the first connecting rod 31. Therefore, the slider assembly 2 and the ejector plate group 3 produce relative movement, so that the inclined ejector rod 71 slides along the inclined hole, and then the buckle slot 711 connected to the other end of the inclined ejector rod 71 is displaced and gradually separated from the undercut part of the product. When the buckle slot 711 is completely separated from the undercut part of the product, that is, the ejector plate group 3 is located at the second extreme position in the stroke cavity 23, as the mold opening action continues, the buckle slot 711 will move away from the product together with the slider assembly 2, and the demolding is completed.

[0045] Optionally, a T-shaped slot is provided on the inclined ejector seat 7, and one end of the inclined ejector rod 71 is slidably connected to the T-shaped slot via a T-shaped slider, so that the inclined ejector rod 71 can be adapted and adjusted when sliding in the inclined hole.

[0046] Compared with the prior art, the sliding inclined ejector delayed action mechanism of the utility model connects the ejector plate group and the delay mechanism through the first connecting rod, thereby realizing precise control of the action timing of the ejector plate group. Moreover, since the first connecting rod is connected to the center position of the ejector plate group, the ejector plate group is subjected to more balanced force during the sliding process, thereby reducing the risk of deformation or damage caused by uneven force.

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
