Description

Technical Field

[0001] The invention relates to the technical field of injection molding machines, and in particular to a camel-type double-injection synchronous shifting mechanism and a shifting method for controlling the same. Background Art

[0002] At present, in the double injection structure of the injection molding machine, two injection parts are arranged horizontally or vertically and crosswise to meet the product requirements of double injection. Both of these injection molding solutions have a big problem, which is that they require a high space for injection molding.

[0003] In order to save space, the prior art uses a camel-type double injection scheme for injection molding of plastic parts. However, when the camel-type double injection is moving forward and backward, two independent hydraulic control systems are used to control the two injection components respectively, and the two sets of actions are independent of each other. Therefore, during the whole movement of the lower injection component, the upper injection component is in a suspended state and will not move with the lower injection component. When the lower injection component moves to a certain position, there is a risk that the upper injection component will separate from the lower injection component and fall.

[0004] In addition, the existing camel-type double-injection injection molding machine has the problem that the injection position of the upper injection part cannot be adjusted, and it can only be used for injection molds with the same injection port. When there are horizontal, height, and angle deviations in the injection port, adjustment cannot be achieved, resulting in limited application scope of the camel-type double-injection injection molding machine.

[0005] In order to solve the problems of asynchronous whole-shift movement of camel-type double injection structure and unadjustable position of upper injection component, a mechanism and whole-shift method for controlling synchronous whole-shift movement of camel-type double injection is proposed. Summary of the invention

[0020] The various aspects of the present invention are described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0021] Embodiment 1: In Figure 1, Figure 2 In the embodiment shown, a mechanism for controlling the synchronous full-shift of camel-type dual injection includes a lower injection component 3 and an upper injection component 2 and an injection seat 4 which are independently arranged in the control system, and the upper injection component 4 is arranged on the injection seat 4 through a differential synchronous full-shift mechanism. Synchronous injection is achieved between the upper injection component and the lower injection component through differential full-shift. That is, when the lower injection component is full-shifted, the upper injection component is in a suspended state and does not move with the lower injection component. When the upper injection component reaches a limited position, the upper injection component in a suspended state can achieve synchronous full-shift with the lower injection component, which effectively solves the problem of asynchronism during full-shift movement of the camel-type dual injection structure.

[0022] The differential synchronous shift mechanism includes an upper injection component bottom plate 1 connected to the upper injection component, a bottom plate base assembly 31 connected to the lower injection component, and an upper and lower plate connection assembly 21 with a multi-directional adjustment function. The upper and lower plate connection assembly 21 is slidably connected to the bottom plate base assembly 31, and a mold adjustment proximity switch 3103 and a synchronous shift limiter are provided on the bottom plate base assembly 31. A differential shift stroke is provided between the synchronous shift limiters. The synchronous shift limiter includes a plurality of limit blocks 3102, and the differential shift stroke is formed between the limit blocks 3102 arranged along the injection direction.

[0023] The bottom plate base assembly 31 is fixed to the injection seat by screws, the upper and lower bottom plate connecting assembly 21 is installed on the bottom plate base assembly 31, and the upper injection component bottom plate 1 is fixed to the upper and lower bottom plate connecting assembly by screws in a camel-like tilt, so that two independent injection units are connected together. The upper injection component bottom plate is tilted upward away from the injection direction.

[0024] The function of the bottom plate base assembly 31 is to provide a base for the upper and lower bottom plate connecting assemblies 21, and at the same time to ensure that the upper injection component can be moved and adjusted relative to the lower injection component.

[0025] like Figure 2 As shown, the base bottom plate assembly 31 includes a base bottom plate 3101, and two sets of linear guide rails are arranged on the base bottom plate. The base plate base assembly is slidably connected to the upper and lower base plate connecting assemblies through the linear guide rails. The base plate base assembly is slidably connected to the upper and lower base plate connecting assemblies through the linear guide rails.

[0026] In this embodiment, the base bottom plate 3101 is a rectangular plate structure as a whole, and a plurality of guide rail mounting holes are arranged on both sides of the plate surface along the length direction of the base bottom plate.

[0027] Each set of linear guide rail pairs includes a linear guide rail 3105 and two guide rail sliders 3106 slidably arranged on the linear guide rail 3105.

[0028] The two linear guide rails 3105 are symmetrically arranged on both sides of the base bottom plate 3101 along the length direction of the base bottom plate 3101. The two linear guide rails 3105 are fixed to the guide rail mounting holes of the base bottom plate by screws, and the guide rail slider 3106 is slidably set on the linear guide rail 3105.

[0029] In order to ensure that the upper injection component does not move after moving to the limited position, a plurality of limit blocks 3102 are installed on the base bottom plate 3101. In this embodiment, there are four limit blocks, which are respectively arranged on both sides of the base bottom plate away from one end of the injection direction and on the inner side of the linear guide rail. Specifically, the four limit blocks are symmetrically arranged at one end of the base bottom plate, and the differential full-shift stroke is formed between the two limit blocks along the length direction. In order to meet the adjustment needs of different differential full-shift strokes, the four limit blocks are adjustably connected to the base bottom plate 3101. Specifically, a waist-shaped adjustment hole is provided on the base bottom plate, and the limit blocks are adjustably connected to the waist-shaped adjustment hole, so as to meet the setting of different differential full-shift strokes, thereby realizing the universal design of the differential synchronous full-shift mechanism.

[0030] In order to detect the displacement change of the upper injection component, two sets of mold adjustment proximity switches 3103 are installed on the base bottom plate 3101, and the mold adjustment proximity switches are installed on the base bottom plate 3101 through a switch bracket 3104. In this embodiment, the two sets of mold adjustment proximity switches 3103 are respectively arranged on one side of the same side limit block facing the injection direction.

[0031] The upper and lower base plate connection assembly 21 includes an integrally movable lower base plate 2101, a horizontal base plate 2102, an integrally movable upper base plate 2111, a vertical adjustment assembly, a horizontal adjustment assembly and an integrally movable hanging angle assembly.

[0032] The whole movable lower bottom plate is a rectangular plate structure. In other embodiments, the whole movable lower bottom plate can also adopt other structures. A plurality of adjustment holes are arranged at both ends of the whole movable lower bottom plate to facilitate the installation and adjustment of the vertical adjustment component and the horizontal adjustment component.

[0033] The horizontal bottom plate 2102 is a rectangular plate structure as a whole, and is smaller than the size of the whole movable lower bottom plate. In other embodiments, the horizontal bottom plate may also adopt other structures. A vertical adjustment member mounting hole is respectively provided at both ends of the horizontal bottom plate, and the vertical adjustment assembly is installed inside the vertical adjustment member mounting hole and connected to the mounting adjustment hole on the whole movable lower bottom plate, so as to achieve the adjustment of the height position of the horizontal bottom plate relative to the whole movable lower bottom plate. Two corner hanging member mounting holes are provided in the middle position of the horizontal bottom plate 2102 for installing the whole movable corner hanging member, and a positioning pin hole is provided on the horizontal bottom plate in the middle position of the two corner hanging member mounting holes, and a positioning pin for achieving positioning is provided inside the positioning pin hole.

[0034] The said lower bottom plate for full movement and the upper bottom plate for full movement are respectively provided with two groups, front and rear, and the said lower bottom plate for full movement 2101 is fixed on the guide rail slider 3106 by screws. One group of lower bottom plates for full movement is arranged in the space where the differential full movement stroke is located and moves within the stroke range of the differential full movement stroke, thereby realizing differential time movement. When the lower bottom plate for full movement completes the differential full movement stroke, the lower bottom plate for full movement interferes with the limit block, thereby driving the upper injection component and the lower injection component to perform full movement together.

[0035] The horizontal adjustment assembly includes a bracket adjustment block 2105 and a bracket adjustment bolt, which are used to adjust the horizontal position of the upper injection component. The horizontal adjustment assembly is arranged at the end of the horizontal bottom plate 2102 and on the whole moving lower bottom plate.

[0036] The vertical adjustment assembly includes an adjustment screw 2103 and an adjustment nut 2104. There are four groups of vertical adjustment assemblies, which are respectively arranged at both ends of the two horizontal base plates 2102 for adjusting the height of the upper injection component in the vertical direction.

[0037] The whole movable hanging corner components are arranged front and back, with two groups arranged at the front and two groups arranged at the back.

[0038] like Figure 4 As shown, each group of the fully movable hanging angle components includes a half 2106, a fully movable front joint 2107 and a fully movable hanging angle 2110.

[0039] The Haff is fixed on the horizontal bottom plate 2102, the front joint 2107 is connected to the Haff 2106, the hanging angle 2110 is rotatably connected to the upper end of the front joint through an angle-adjustable joint pin 2108, and the joint pin is limited by a joint pin retaining ring 2109 to prevent the joint pin 2108 from slipping out from one side.

[0040] Two symmetrical angle adjustment surfaces are axially arranged at the upper end of the front joint 2107, and pin holes are arranged perpendicular to the symmetrical angle adjustment surfaces. The angle adjustment holes are arranged on the symmetrical angle adjustment surfaces and can be rotated to adjust the angle, thereby realizing angle adjustment.

[0041] The whole movable hanging angle is a square block structure. Of course, in other embodiments, the whole movable hanging angle can also adopt other structures. The four corners of the whole movable hanging angle are provided with upper base plate connection holes. The whole movable hanging angle 2110 is connected to the lower plate surface of the whole movable upper base plate 2111 by bolts.

[0042] The entire movable upper base plate 2111 is in a rectangular structure as a whole. Of course, in other embodiments, the entire movable upper base plate may also adopt other structures.

[0043] The height of the front joint of the full-shift hanging corner assembly facing the front of the injection direction is lower than the height of the front joint of the full-shift hanging corner assembly at the rear, thereby realizing the camel-like inclined setting of the bottom plate of the upper injection component.

[0044] The upper and lower base plate connection assembly 21 is used to connect the upper injection component base plate and the base plate base assembly 31. In order to adjust the upper injection component in the vertical direction, a vertical adjustment assembly, namely an adjustment screw and an adjustment nut, is designed. In order to adjust the upper injection component in the horizontal direction, a horizontal adjustment assembly, namely a bracket adjustment block and an adjustment bolt, is designed. In order to adjust the angle of the upper injection component, a full-shift hanging angle assembly is designed.

[0045] Through the upper and lower plate connecting components, the horizontal, vertical and tilt angle adjustments of the upper injection component bottom plate are realized, thereby realizing the adjustment of the injection position and angle of the upper injection component to meet the injection needs of injection ports with different injection angles. The mechanism is used to control the camel-type double injection synchronous shifting mechanism, which realizes the differential synchronous shifting of the upper injection component and the lower injection component. At the same time, the upper injection component can be adjusted in the horizontal, vertical and angular directions, with a wider range of applications and good general performance.

[0046] like Figure 5 As shown, the working principle of the camel-type double injection differential synchronous shifting mechanism is: Since the hydraulic control systems of the upper injection component and the lower injection component are independently set, when in use, the hydraulic control system of the upper injection component is independently controlled, and the hydraulic system of the lower injection component is also independently controlled. Therefore, when camel-style double injection is required, the hydraulic control system of the lower injection component controls the movement of the lower injection component shifting cylinder 6, and the lower injection component performs the shifting movement. When the lower injection component is shifting, the upper injection component shifting cylinder 5 is in a suspended state and does not move with the lower injection component. Instead, the base plate base assembly 31 moves with the injection seat, and at this time, the base plate base assembly 31 slides relative to the upper and lower base plate connecting assembly 21.

[0047] When the base plate base assembly 31 moves to the limit position, that is, when the mold adjustment proximity switch 3103 on the base plate 3101 senses that the upper injection component has reached the limit position, the limit block prevents the base plate from continuing to slide, and the limit block plays a limiting role. At this time, the base plate no longer slides relative to the upper and lower base plate connecting assembly 21, but drives the upper and lower base plate connecting assembly 21, that is, drives the upper injection component in a suspended state to move together, thereby realizing the synchronous movement of the lower injection component and the upper injection component.

[0048] Embodiment 2: A method for controlling the synchronous whole-shift of camel-style double injection. When camel-style double injection is required, the hydraulic control system of the lower injection component is used to control the action of the cylinder of the lower injection component, thereby driving the lower injection component to perform whole-shift movement. At this time, the whole-shift cylinder of the upper injection component is in a suspended state and does not move together with the lower injection component, thereby realizing the differential movement between the upper injection component and the lower injection component.

[0049] When the mold adjustment proximity switch on the base bottom plate senses that the upper injection component has reached a limited position, the synchronous movement limiter blocks the base bottom plate from continuing to slide, driving the upper injection component in a suspended state to move together, thereby achieving synchronous movement of the lower injection component and the upper injection component.

[0050] Since the hydraulic control system of the upper injection component is independent, when the lower injection component is moving, the upper injection component moving cylinder is in a suspended state and does not move with the lower injection component. When the mold adjustment proximity switch senses that the upper injection component has reached the limited position, the limit block acts to drive the upper injection component in a suspended state to move together, thereby achieving synchronous movement of the lower injection component and the upper injection component.

[0051] The method for controlling the synchronous full-shift of camel-type double injections, since the hydraulic control systems of the upper injection component and the lower injection component are independent of each other, can realize that the upper injection component is in a suspended state during the initial movement of the lower injection component by controlling the synchronous full-shift mechanism of the camel-type double injection, and does not move together with the lower injection component; when the mold adjustment proximity switch senses that the upper injection component has reached a limited position, the synchronous full-shift limiter blocks the bottom plate of the base from continuing to slide, thereby driving the upper injection component to move together; the method realizes the differential synchronous full-shift double injection of the upper injection component and the lower injection component, effectively solving the problem that the existing camel-type double injection structure is not synchronized during full-shift movement, and there is a risk of the upper injection component being separated from the lower injection component and thus falling; and the method has a simple structure and is easy to operate.

[0052] Embodiment 3: exist Figure 6 In the embodiment shown, a mechanism for controlling camel-type double injection synchronous adjustment and shifting includes a differential synchronous adjustment and shifting mechanism, wherein the differential synchronous adjustment and shifting mechanism includes an upper injection component bottom plate 1 connected to the upper injection component, a bottom plate base assembly 31 connected to the lower injection component, and an upper and lower plate connecting assembly 21 with a multi-directional adjustment function, wherein the upper and lower plate connecting assembly 21 is slidably connected to the bottom plate base assembly 31, and a mold adjustment proximity switch 3103 and a synchronous adjustment and shifting limiter are arranged on the bottom plate base assembly 31.

[0053] In this embodiment, an adjustable movable connection is adopted between the upper injection component bottom plate 1 and the lower-lower plate connecting assembly 21 .

[0054] A differential full-shift stroke L is arranged between the synchronous full-shift limiters. The synchronous full-shift limiters include a plurality of limit blocks 3102, and the differential full-shift stroke is formed between the limit blocks 3102 arranged along the injection direction.

[0055] The upper and lower base plate connection assembly 21 includes a whole-moving lower base plate 2101, a horizontal base plate 2102, a whole-moving upper base plate 2111, a vertical adjustment assembly, a horizontal adjustment assembly and a whole-moving hanging angle assembly. The whole-moving lower base plate is provided to realize a sliding connection with the base plate base assembly, thereby realizing the relative movement of the whole-moving lower base plate relative to the base plate base assembly. The setting of the horizontal base plate can facilitate the setting of the whole-moving hanging angle assembly, and also facilitate the adjustment of the upper injection component base plate in the horizontal and vertical directions. The whole-moving upper base plate is provided to facilitate the connection with the upper injection component base plate and the setting of the whole-moving hanging angle assembly. The whole-moving hanging angle assembly is provided to facilitate the adjustment of the angle of the upper injection component base plate, thereby realizing the adjustment of the injection angle of the upper injection component. The upper injection component bottom plate can be adjusted in the horizontal, vertical and tilted directions, thereby adjusting the injection position and angle of the upper injection component to meet the injection needs of injection ports at different injection angles. The mechanism is used to control the camel-type double-injection synchronous shifting mechanism, which realizes the differential synchronous shifting of the upper injection component and the lower injection component. At the same time, the upper injection component can be adjusted in the horizontal, vertical and angular directions, which has a wider range of applications and good general performance.

[0056] The horizontal adjustment assembly is arranged at the end of the horizontal bottom plate 2102 and on the entire movable lower bottom plate 2101, and the horizontal adjustment assembly includes a bracket adjustment block 2105 and a bracket adjustment bolt.

[0057] The vertical adjustment components are arranged at two ends of the horizontal bottom plate 2102 , and the vertical adjustment components include an adjustment screw 2103 and an adjustment nut 2104 .

[0058] The said adjustment and displacement hanging angle assembly comprises a half 2106, an adjustment and displacement front joint 2107 and an adjustment and displacement hanging angle 2110. The said half is fixed on the horizontal bottom plate 2102, the said adjustment and displacement front joint 2107 is connected to the half 2106, and the said adjustment and displacement hanging angle 2110 is rotatably connected to the upper end of the adjustment and displacement front joint in an angle-adjustable manner. In this embodiment, an angle-adjusting ball head is provided on the adjustment and displacement front joint, and a ball head hole is provided on the adjustment and displacement hanging angle, and the ball head hole is rotatably connected to the angle-adjusting ball head, so as to realize the angle adjustment of the adjustment and displacement hanging angle.

[0059] The base plate base assembly 31 is arranged on the injection seat, and a guide rail slider is arranged on the base plate base assembly 31. Two linear guide rails 3105 are symmetrically arranged on the entire lower base plate of the upper and lower base plate connecting parts, and the linear guide rails 3105 are slidably connected with the guide rail slider 3106.

[0060] In addition, the camel-type dual injection synchronous shifting mechanism for controlling the same also includes a lower injection component 3 and an upper injection component 2 and an injection seat 4 which are independently arranged in the control system, and the upper injection component 4 is arranged on the injection seat 4 through a differential synchronous shifting mechanism.

[0061] The upper injection component and the lower injection component achieve synchronous injection through differential movement. That is, when the lower injection component is moving, the upper injection component is in a suspended state and does not move with the lower injection component. When the upper injection component reaches a limited position, the upper injection component in a suspended state can achieve synchronous movement with the lower injection component, effectively solving the problem of asynchronous movement of the camel-type double injection structure.

[0062] The camel-type double injection differential synchronous shifting mechanism described in the above embodiment, by setting up a differential synchronous shifting mechanism, realizes that during the initial shifting process of the lower injection component, the upper injection component is in a suspended state and does not move together with the lower injection component. When the lower injection component moves to the extreme position of the upper injection component, the upper injection component moves synchronously with the lower injection component, thereby ensuring the synchronous shifting of the lower injection component and the upper injection component during the injection process, avoiding the risk of the upper injection component and the lower injection component detaching and falling.

[0063] Finally, it should be noted that the above examples are only specific embodiments of the present invention. Obviously, the present invention is not limited to the above examples, and there may be multiple variations, such as changing the installation position of the oil cylinder and the motor, changing the motion form of the injection mold, etc. All variations that can be directly derived or associated with the content disclosed by a person skilled in the art should be considered to be within the scope of protection of the present invention.

10. A method for controlling the synchronous movement of camel-type double injection, characterized in that: It utilizes the synchronous shifting mechanism for controlling camel-type double injection as described in any one of claims 1 to 9, and the shifting method is as follows: when camel-type double injection is required, the action of the lower injection component is controlled by the hydraulic control system of the lower injection component, and the lower injection component performs a shifting movement. At this time, the shifting cylinder of the upper injection component is in a suspended state, and does not move together with the lower injection component, thereby realizing differential movement; when the mold adjustment proximity switch on the bottom plate of the base senses that the upper injection component has reached a limited position, the synchronous shifting limiter blocks the bottom plate of the base from continuing to slide, and drives the upper injection component in a suspended state to move together, thereby realizing synchronous shifting of the lower injection component and the upper injection component.
