Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and in particular to a docking mechanism for the body of an injection molding machine. Background Technology

[0002] An injection molding machine consists of an injection unit and a mold clamping unit, which are respectively mounted on two machine bodies. When assembling the injection molding machine, the two bodies must first be joined together, and then the specific components of the injection unit and mold clamping unit are installed onto the two machine bodies. Existing machine body joining structures can be found in the attached diagram of this solution's instruction manual. Figure 1 As shown, the assembly includes a docking structure and a bolt assembly. The docking structure includes a docking seat located between the two bodies, which can simultaneously engage with the two docking seats for partial positioning. The positioning block can be detachably connected to one of the docking seats. When the positioning block is connected to the docking seat, the positioning block is docked with the docking block on the other body by moving the body. At least two sets of docking structures are spaced apart between the two bodies. After all docking structures are docked, the two bodies are connected and locked together using the bolt assembly.

[0003] In actual production, the length of the injection screw of an injection molding machine may be lengthened according to the needs of some consumers. When the injection screw is installed on the machine body, the extended part will interfere with the installation space on the other machine body. It is necessary to increase the distance between the two machine bodies to install the mold closing part normally. However, the machine bodies assembled with the above docking structure can only form a fixed distance. Therefore, the injection molding machine body assembled with the above docking structure cannot accommodate the extended screw. There is still room for improvement in this docking structure. Utility Model Content

[0004] To address the shortcomings of existing injection molding machine body docking structures that cannot change the distance between the two machine bodies, making it difficult for the original machine body to adapt to the injection screw after it is lengthened, the purpose of this utility model is to provide a docking mechanism that allows the injection molding machine body to adapt to injection screws of different lengths.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] A docking mechanism for injection molding machine bodies includes a docking structure capable of docking two machine bodies and a fastening assembly for connecting and fixing the two machine bodies. The docking structure includes a first docking component fixed to one machine body and several second docking components of different lengths, one of which can be detachably and fixedly connected to the other machine body according to the working conditions. The end of the second docking component facing the first docking component can be spliced ​​and positioned with the first component.

[0007] With the above solution, during installation, the installer can select the appropriate second mating part to match the actual extension of the injection screw. After installation, a suitable gap will be maintained between the machine bodies to allow the subsequent injection molding and mold closing modules to be installed normally. Therefore, the structure of this solution increases the compatibility between the injection molding machine body and injection screws of different specifications.

[0008] Preferably, the fuselage and the second docking component are connected by a detachable structure, which includes a positioning structure for determining the installation position of the second docking component and a locking component for fixing the second docking component relative to the fuselage.

[0009] Preferably, the positioning structure includes a mounting base protruding from the body and a first positioning block that engages with both the mounting base and the second docking component.

[0010] Preferably, a second positioning block is provided between the opposite ends of the second docking component and the first docking component, which will simultaneously engage with both components after they are docked.

[0011] Preferably, both the first and second positioning blocks are cylindrical positioning blocks. Arc-shaped splicing grooves are provided between the mounting base and the second docking component, as well as between the first docking component and the second docking component, for the cylindrical positioning blocks to be filled and spliced. At least two sets of docking structures are provided at intervals between the two bodies.

[0012] Using the above solution, the first and second positioning blocks have the same shape. Therefore, the mounting base and the first mating component are equivalent to the mating base in the prior art. When the injection molding machine uses a conventional injection screw, the mating method described in the prior art can still be used, connecting the mounting base and the first mating component via a cylindrical positioning block. When the injection molding machine uses an extended injection screw, only a second mating component needs to be added between the mounting base and the first mating component, and its installation position can be compensated for by using a cylindrical positioning block to position it. Therefore, the structure of this solution only requires... By designing several second docking components with shapes matching the cylindrical positioning blocks and different lengths, docking of the two fuselages at different distances can be achieved, reducing the design difficulty. In this scheme, the number of docking structures is preferably two sets. Since this scheme limits the second positioning block to a cylindrical positioning block, when there is only one set of docking structures, the outer ring wall of the second positioning block is easily deflected after it fits with the arc splicing groove. After adding two sets of docking structures and fully docking them, one set of docking structures will limit the deflection of the other set of docking structures, forming a more stable docking relationship, which significantly simplifies the steps of fuselage assembly and calibration.

[0013] Preferably, the first positioning block is detachably fixed in the arc-shaped splicing groove of the mounting base or the second docking component facing the mounting base, and the second positioning block is detachably fixed in the arc-shaped splicing groove of the first docking component or the second docking component facing the first positioning component.

[0014] Using the above solution, when the components of the fuselage and docking structure are spliced ​​together but not locked, the installer will make fine adjustments to the fuselage according to its actual position to make it closer to the standard installation position. Fine adjustments are usually made by tapping with a copper rod, which causes the fuselage to vibrate. However, in this solution, the two cylindrical positioning blocks are connected to one of the mounting base, the second docking component, and the first docking component to form a whole. If the locking component or fastening assembly is not locked or not fully locked, the cylindrical positioning blocks are not easy to disengage, which can reduce the situation of disengagement from the assembly position due to vibration during fine adjustments.

[0015] Preferably, a pre-positioning structure is provided between the mounting base, the first positioning block, and the second docking component to keep the three in a straight line.

[0016] Preferably, the pre-positioning structure includes a connecting plate, on which a plurality of limiting posts are spaced apart and can simultaneously engage with the mounting base, the second docking component and the first positioning block. The connecting plate can simultaneously engage with the mounting base, the first positioning component and the second docking component.

[0017] Using the above solution, when the second docking component, the first positioning block, and the mounting base are spliced ​​together, the first positioning block can easily rotate around the inner wall of the arc-shaped splicing groove after it abuts against the inner wall. The pre-positioning structure in this solution can pre-determine the position of the three components before the locking component fixes them. After locking, the probability of deflection will be reduced, thus achieving the effect of preventing the second docking component from deflecting.

[0018] Preferably, the locking component includes several sets of first bolt assemblies of different lengths, one of which can be selected according to the working conditions. The first bolt assembly can connect the second docking component and the machine body to press and fix the second docking component and the first positioning component on the mounting base.

[0019] Preferably, the fastening assembly includes several sets of second bolt assemblies of different lengths, one of which can be selected according to the working conditions. The second bolt assemblies are connected in series between the two machine bodies to press and fix the second docking parts and the first docking parts together.

[0020] This utility model has significant technical effects due to the adoption of the above technical solutions: During installation, the installer can select the corresponding second mating part to match the actual extension of the injection screw. After installation, a suitable gap will be maintained between the machine bodies to allow the subsequent injection molding and mold closing modules to be installed normally. Therefore, the structure of this solution increases the compatibility between the injection molding machine body and injection screws of different specifications. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0028] Example

[0029] A docking mechanism for an injection molding machine body includes a docking structure capable of docking two machine bodies 1, according to... Figure 2As shown, the docking structure includes a first docking component 5 fixed to one body 1 and several second docking components 6 of different lengths, one of which can be detachably and fixedly connected to another body 1 according to the working conditions. A second positioning block 9 is provided between the opposite ends of the second docking component 6 and the first docking component 5, which will simultaneously splice with the two after docking. In this embodiment, the second positioning block 9 is a cylindrical positioning block. Both ends of the first docking component 5 and the second docking component 6 are provided with arc-shaped splicing grooves 10 for the second positioning block 9 to be filled and spliced ​​with each other. The second positioning block 9 can be detachably fixed in the arc-shaped splicing groove 10 facing the first positioning component of the first docking component 5 or the second docking component 6. In this embodiment, two sets of docking structures are provided at intervals between the two bodies 1.

[0030] The second docking component 6 determines its installation position on the fuselage 1 through a positioning structure, according to Figures 3-5 As shown, the positioning structure includes a mounting base 7 protruding from the body 1. A first positioning block 8 is provided between the mounting base 7 and the second docking component 6, which simultaneously engages with both when they are docked. In this embodiment, the first positioning block 8 is a cylindrical positioning block. An arc-shaped splicing groove 10 is provided between the mounting base 7 and the second docking component 6 for the first positioning block 8 to be filled and positioned. The first positioning block 8 can be detachably fixed in the arc-shaped splicing groove 10 at the end of the mounting base 7 or the second docking component 6 facing the mounting base 7. Figure 5 As shown, in this embodiment, a screw 15 is inserted inside the first positioning block 8. The screw 15 is threadedly connected to the second docking component 6. In this scheme, the first positioning block 8 is equivalent to the second positioning block 9. Therefore, the second positioning block 9 is also connected to the first docking component 5 or the second docking component 6 by a screw 15.

[0031] A pre-positioning structure is provided between the mounting base 7, the first positioning block 8, and the second docking component 6 to keep the three in a straight line. Figure 5 As shown, the pre-positioning structure includes a connecting plate 11. The connecting plate 11 is provided with a plurality of limiting posts 12 that can be simultaneously inserted and engaged with the mounting base 7, the second docking component 6, and the first positioning block 8. The connecting plate 11 can simultaneously overlap and engage with the mounting base 7, the first positioning component, and the second docking component 6. In this embodiment, the limiting posts 12 are limiting pins. The connecting plate 11 is provided with through holes 16 for the limiting pins to pass through. The mounting base 7, the first positioning component, and the first positioning block 8 are all provided with positioning holes 17 for the limiting pins to be inserted into. The limiting pins are tightly fitted or interference-fitted with the through holes 16 and the positioning holes 17.

[0032] The second docking component 6 is fixed to the fuselage 1 by a locking component, according to Figure 3 , 5As shown, the locking component includes several sets of first bolt assemblies 13 of different lengths, one of which can be selected according to the working conditions. The first bolt assembly 13 can connect the second docking component 6 to the machine body 1, pressing and fixing the second docking component 6 and the first positioning component onto the mounting base 7. Figure 5 As shown, in this embodiment, two fixing petals 18 protrude from both sides of the second docking component 6, and the first bolt assembly 13 passes through the fixing petals 18 and is connected to the body 1.

[0033] After the docking structures are connected, they are fixed by fastening components, according to Figure 2 As shown, the fastening assembly includes several sets of second bolt assemblies 14 of different lengths, one of which can be selected according to the working conditions. The second bolt assembly 14 is connected in series between the two machine bodies 1 to press and fix the second docking part 6 and the first docking part 5 together.

[0034] Based on the above structure, refer to Figures 2-5 It can be seen that the assembly process of a docking structure for the injection molding machine body 1 in this embodiment is as follows:

[0035] First, select a suitable second docking component 6 according to the length of the injection screw. Connect the first positioning block 8 to the second docking component 6 with screws 15 to form a whole. Then, abut the first positioning block 8 against the arc-shaped splicing groove 10 on the mounting base 7. Next, insert the limiting post 12 into the through hole 16 on the connecting plate 11, and then insert it into the positioning hole 17. When all the limiting posts 12 are inserted into the through hole 16 and the positioning hole 17, the mounting base 7, the first positioning block 8, and the second docking component 6 are pre-positioned. Next, pass the first bolt assembly 13 through the fixing petal 18 and connect it to the machine body 1. Then, tighten the first bolt assembly 13 to fix the second docking component 6 to the machine body 1 to form a whole. Repeat the above process. After both second docking parts 6 are fixed, start docking the two bodies 1. First, fix the second positioning block 9 to the second docking part 6 or the first docking part 5 with screws 15 to form a whole. Next, use lifting equipment (such as a crane) to lift one body 1 and bring it close to the other body 1. When the second docking part 6 is close to the first docking part 5, lower the body 1 to close to the ground. At this time, the body 1 can be tapped with a copper rod for fine adjustment to drive both sets of first docking parts 5 and second docking parts 6 to complete the splicing. Then, use the second bolt assembly 14 to connect the two bodies 1 and lock the docking structure. Finally, lower the body 1 completely to complete the assembly.

[0036] In this embodiment, when the docking structure is applied, the installer can select the corresponding second docking component 6 to match the actual extension of the injection screw. After installation, a suitable gap will be maintained between the machine bodies 1 so that the subsequent injection molding part and mold closing part modules can be installed normally. Therefore, the structure of this solution increases the compatibility between the machine body 1 of the injection molding machine and injection screws of different specifications.

[0037] In this embodiment, the first positioning block 8 and the second positioning block 9 have the same shape. Therefore, the mounting base 7 and the first docking component 5 are equivalent to the docking seat on the machine body 1 in the prior art. When the injection molding machine uses a conventional injection screw, the existing docking structure and docking method can still be used. The mounting base 7 and the first docking component 5 can be docked through a cylindrical positioning block. When the injection molding machine uses an extended injection screw, only a second docking component 6 needs to be added between the mounting base 7 and the first docking component 5. The installation position can be positioned by a cylindrical positioning block to compensate for the extended part of the injection screw. Therefore, the structure of this solution only needs to design several second docking components 6 with shapes matching the cylindrical positioning blocks and different lengths to achieve docking of the two machine bodies 1 at different distances, which reduces the design difficulty.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
