Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of injection molding machines, in particular to a synchronous moving mechanism and method for controlling a double-injection camel type. BACKGROUND

[0002] Currently, in the double-injection structure of an injection molding machine, two injection components are arranged horizontally or arranged vertically and crosswise to achieve the product demand of double injection. Both of the two injection molding schemes have a big problem, which is that they have high requirements for the space of injection.

[0003] In order to save space, the prior art adopts a double-injection camel type to perform injection molding of plastic parts. However, when the double-injection camel type moves forward and backward, two sets of independent hydraulic control systems are used to control two injection components respectively, and the two sets of actions are independent of each other. Therefore, the lower injection component moves in the process of moving forward and backward, and the upper injection component is in a suspended state and does not move with the lower injection component. When the lower injection component moves to a certain position, the upper injection component is separated from the lower injection component and falls down.

[0004] In addition, the existing double-injection camel type injection molding machine has an unadjustable injection position of the upper injection component, and can only be applied to injection molds with the same injection port. When there is a horizontal, height, and angle deviation in the injection port, the injection molding machine cannot be adjusted, which limits the application range of the double-injection camel type injection molding machine.

[0005] In order to solve the problems of different steps of the double-injection camel type structure when moving forward and backward, the separation of the upper injection component from the lower injection component, and the unadjustable position of the upper injection component, a synchronous moving mechanism and method for controlling a double-injection camel type are provided. SUMMARY

The control mechanism for the camel type double injection synchronous movement mechanism realizes initial asynchronous movement of the upper injection part and the lower injection part during double injection by arranging a differential synchronous movement mechanism, when the mold adjusting proximity switch detects that the lower injection part moves to interfere with the synchronous movement limiting piece, the upper injection part moves synchronously with the lower injection part, thereby realizing synchronous movement double injection of the upper injection part and the lower injection part.

[0009] Preferably, the synchronous movement limiting piece comprises a plurality of limiting blocks, and the differential movement stroke is formed between the limiting blocks arranged in the injection direction. The synchronous movement limiting piece preferably comprises a plurality of limiting blocks, the limiting blocks are used to limit the upper and lower plate connecting assembly, i.e. to limit the upper injection part, thereby realizing synchronous movement of the upper injection part and the lower injection part when the lower injection part moves to the limiting position.

[0037] In the embodiment, the base plate 3101 is in a whole rectangular plate structure, a plurality of guide rail mounting holes are arranged on both sides of the plate surface of the base plate in the length direction.

[0038] Each set of linear guide rail pairs comprises one linear guide rail 3105 and two guide rail sliding blocks 3106 slidingly arranged on the linear guide rail 3105.

A plurality of adjustment holes are provided at both ends of the synchronous displacement lower plate, which facilitates the installation and adjustment of the vertical adjustment assembly and the horizontal adjustment assembly.

[0044] The horizontal plate 2102 is a rectangular plate structure as a whole, and smaller than the size of the synchronous displacement lower plate. In other embodiments, the horizontal plate can also adopt other structures. A vertical adjustment member mounting hole is provided at each end of the horizontal plate, the vertical adjustment assembly is installed inside the vertical adjustment member mounting hole and connected with the mounting and adjustment hole on the synchronous displacement lower plate, thereby realizing the adjustment of the height position of the horizontal plate relative to the synchronous displacement lower plate. Two hanging corner member mounting holes are provided at the middle position of the horizontal plate 2102 for installing the synchronous displacement hanging corner assembly, and a positioning pin hole is provided on the horizontal plate at the middle position of the two hanging corner member mounting holes, and a positioning pin is provided inside the positioning pin hole for realizing positioning.

[0045] The integral moving lower bottom plate and the integral moving upper bottom plate are respectively provided with two groups of front and back, the integral moving lower bottom plate 2101 is fixed on the guide rail sliding block 3106 through a screw, one group of the integral moving lower bottom plate is arranged in the space of the differential integral moving stroke and moves in the stroke range of the differential integral moving stroke, so that the differential motion is realized, when the integral moving lower bottom plate runs through the differential integral moving stroke, the integral moving lower bottom plate interferes with the limiting block, so as to drive the upper injection component to move integrally with the lower injection component.

[0046] The horizontal adjusting assembly includes a bracket adjusting block 2105 and a bracket adjusting bolt, is used for adjusting the position of the upper injection component in the horizontal direction, and is arranged at the end of the horizontal bottom plate 2102 and on the integral moving lower bottom plate.

[0047] The vertical adjusting assembly includes an adjusting screw 2103 and an adjusting nut 2104, and is provided with four groups, which are arranged at the two ends of the two horizontal bottom plates 2102, and is used for adjusting the height of the upper injection component in the vertical direction.

[0048] The integral moving hanging angle assembly is arranged in front and back, two groups are arranged in front, and two groups are arranged in back.

[0049] As shown in Figure 4 Each group of the integral moving hanging angle assembly includes a half 2106, an integral moving front joint 2107 and an integral moving hanging angle 2110.

[0050] The half is fixed on the horizontal bottom plate 2102, the integral moving front joint 2107 is connected to the half 2106, the integral moving hanging angle 2110 is rotationally connected to the upper end of the integral moving front joint through an integral moving joint pin 2108 in an angle-adjusting mode, and the integral moving joint pin is limited by a joint pin stop ring 2109 to prevent the integral moving joint pin 2108 from sliding out from one side.

[0051] Two symmetrical angle adjusting surfaces are arranged on the upper end of the integral moving front joint 2107 in an axial direction, a pin shaft hole is arranged perpendicularly to the symmetrical angle adjusting surfaces, an angle adjusting hole is arranged on the integral moving hanging angle, the angle adjusting hole is sleeved on the symmetrical angle adjusting surfaces and can be rotationally adjusted, so that the angle is adjusted.

[0052] The integral moving hanging angle is in a square block structure, and of course, the integral moving hanging angle can also adopt other structures in other embodiments. Upper bottom plate connecting holes are arranged on the four corners of the integral moving hanging angle. The integral moving hanging angle 2110 and the lower plate surface of the integral moving upper bottom plate 2111 are connected in an integrated mode through a screw.

[0053] The integral moving upper bottom plate 2111 is in a rectangular structure, and of course, the integral moving upper bottom plate can also adopt other structures in other embodiments.

[0054] The height of the integral moving front joint in the integral moving corner assembly towards the front of the injection direction is lower than the height of the integral moving front joint in the rear integral moving corner assembly, so as to realize the camel-shaped inclined arrangement of the upper injection component bottom plate.

[0055] The upper and lower plate connecting assembly 21 is used to connect the upper injection component bottom plate and the bottom plate base assembly 31. In order to adjust the upper injection component in the vertical direction, a vertical adjusting assembly, i.e. an adjusting screw and an adjusting nut, is designed. In order to adjust the upper injection component in the horizontal direction, a horizontal adjusting assembly, i.e. a bracket adjusting block and an adjusting bolt, is designed. In order to adjust the angle of the upper injection component, an integral moving corner assembly is designed.

[0056] Through the upper and lower plate connecting assembly, the adjustment of the upper injection component bottom plate in the horizontal direction, the vertical direction and the inclination angle is realized, so as to realize the adjustment of the injection position and the angle of the upper injection component to meet the needs of different injection angles of the injection port. The camel-shaped double injection synchronous integral moving mechanism is used to control the differential synchronous integral movement of the upper injection component and the lower injection component. At the same time, the adjustment of the upper injection component in the horizontal direction, the vertical direction and the angle direction is realized, the application range is wider, and the general performance is good.

[0057] As shown in Figure 5 the working principle of the camel-shaped double injection differential synchronous integral moving mechanism:

[0058] Since the hydraulic control systems of the upper injection component and the lower injection component are independently arranged, the upper injection component hydraulic control system is independently controlled during use, and the lower injection component hydraulic system is also independently controlled. Therefore, when camel-shaped double injection is needed, the lower injection component integral moving cylinder 6 is controlled to move by the lower injection component hydraulic control system, and the lower injection component moves integrally. When the lower injection component moves integrally, the upper injection component integral moving cylinder 5 is in a suspended state and does not move integrally with the lower injection component. Instead, the bottom plate base assembly 31 moves integrally with the injection seat, and at this time, the bottom plate base assembly 31 slides relative to the upper and lower plate connecting assembly 21.

[0059] When the bottom plate base assembly 31 moves to the limit position, i.e. when the mold adjusting proximity switch 3103 on the bottom plate 3101 senses that the upper injection component reaches the limit position, the limit block blocks the bottom plate from continuing to slide, and the limit block functions as a limit. At this time, the bottom plate does not slide relative to the upper and lower plate connecting assembly 21, but drives the upper and lower plate connecting assembly 21, i.e. drives the upper injection component in a suspended state to move integrally, so as to realize the synchronous integral movement of the lower injection component and the upper injection component.

[0060] Embodiment 2:

[0061] The application relates to a method for controlling synchronous whole-moving of a camel-type double injection, when camel-type double injection is needed, the lower injection part oil cylinder is controlled to move by the lower injection part hydraulic control system, the lower injection part is driven to move, at this time, the upper injection part whole-moving oil cylinder is in a suspended state and does not move with the lower injection part, so that the differential motion between the upper injection part and the lower injection part is realized.

[0062] When the mold adjusting proximity switch on the base bottom plate senses that the upper injection part reaches the limited position, the synchronous whole-moving limiting part blocks the base bottom plate from continuously sliding, the upper injection part in the suspended state is driven to move, so that the synchronous whole-moving of the lower injection part and the upper injection part is realized.

[0063] Since the upper injection part hydraulic control system is independent, when the lower injection part moves, the upper injection part whole-moving oil cylinder is in a suspended state and does not move with the lower injection part. When the mold adjusting proximity switch senses that the upper injection part reaches the limited position, the limiting block acts to drive the upper injection part in the suspended state to move, so that the synchronous whole-moving of the lower injection part and the upper injection part is realized.

[0064] The method for controlling synchronous whole-moving of a camel-type double injection, since the upper injection part and the lower injection part hydraulic control systems are independent, the upper injection part is in a suspended state and does not move with the lower injection part in the initial moving process of the lower injection part by the mechanism for controlling synchronous whole-moving of a camel-type double injection, when the mold adjusting proximity switch senses that the upper injection part reaches the limited position, the synchronous whole-moving limiting part blocks the base bottom plate from continuously sliding, so that the upper injection part is driven to move, the method realizes the differential synchronous whole-moving double injection of the upper injection part and the lower injection part, effectively solves the problem that the existing camel-type double injection structure moves asynchronously and the upper injection part and the lower injection part are separated to cause falling, and the method is simple in structure and convenient to operate.
