Utility Model Content

[0003] The present application provides a one-cavity multi-mold injection mold for a sailing cup handle, which effectively solves the demoulding problem of the handle body.

[0006] By adopting the above technical solution, when the mold is closed, a plurality of forming rods simultaneously form a plurality of mounting holes. After the mold is opened after injection molding, a plurality of driving parts control the movement of a plurality of forming rods so that the plurality of forming rods move away from two forming holes on the same handle body, so that the plurality of forming rods will not contact the plurality of handle bodies, so that the plurality of handle bodies after being formed can be smoothly ejected and demolded by the ejector pin.

The slider is provided with a socket for inserting the push rod, and the distance from the socket to the adjacent first forming cavity gradually increases from the top end of the socket to the bottom end of the socket.

[0008] By adopting the above technical solution, when the mold is opened, the movable template will be driven away from the fixed template by the injection molding machine, and the relative slider will be away from the ejector rod. Under the action of the ejector rod, the force of the fixed template movement will be converted into the force of the slider movement, causing the slider to move and drive the molding rod to move away from the handle body, and finally causing the molding rod to disengage from the two mounting holes.

[0009] Preferably, the movable template is provided with a plurality of second slide grooves, a plurality of the sliders are slidably connected in the plurality of second slide grooves, a plurality of the second slide grooves are provided with fixing holes on their bottom surfaces, a plurality of the fixing holes are provided with fixing seats, a first slide hole is provided on the fixing seat, a second slide hole is provided on the top wall of the first slide hole, an insert block is slidably connected in the second slide hole, an annular baffle is provided at the bottom of the insert block, the annular baffle is slidably connected in the first slide hole, a spring is provided in the first slide hole, one end of the spring abuts against the bottom surface of the first slide hole, and the other end abuts against the bottom end of the annular baffle, A first slot and a second slot for inserting the top end of the plug block are provided on the bottom surfaces of the plurality of sliders, the second slot is located on the side of the first slot away from the adjacent first molding area, and the plurality of second sliding holes are respectively located on the movement paths of the adjacent first slots and the second slots.

When the mold is in a closed mold state, the plurality of second slots are respectively connected to the plurality of second sliding holes, and the plurality of springs press the top ends of the plurality of plug blocks into the plurality of second slots.

[0015] Preferably, a stopper is provided at the connection between the feed channel and the plurality of second molding cavities, and a pressurizing channel is formed between the plurality of stoppers and the fixed mold plate when the mold is closed.

[0016] By adopting the above technical solution, the setting of the pressurized channel can increase the filling pressure and the holding pressure when filling the plastic, thereby improving the injection molding efficiency and the injection molding quality of the product.

The fixing seats 8 are provided with a first sliding hole 81, and the top wall of the first sliding hole 81 is provided with a second sliding hole 82, and the diameter of the second sliding hole 82 is smaller than the diameter of the first sliding hole 81.

The four second sliding holes 82 are respectively located on the movement paths of the adjacent first slots 512 and the second slots 513.

[0048] Figure 1 , Figure 7-Figure 9A spring 85 is provided in the first sliding hole 81, one end of the spring 85 abuts against the bottom surface of the first sliding hole 81, and the other end abuts against the bottom end of the annular baffle 84. When the mold is in a fully open state, the four first slots 512 are respectively connected to the four second sliding holes 82, and the four springs 85 press the top ends of the four plug-in blocks 83 into the first slots 512. When the mold is in a closed state, the second slots 513 are respectively connected to the four second sliding holes 82, and the four springs 85 press the top ends of the four plug-in blocks 83 into the four second slots 513.

[0049] The injection molding process of the mold of this application is as follows.

[0050] The mold is initially in an open state, at which time the four second slots 513 are connected to the four second slide holes 82 respectively, and the four springs 85 press the four annular baffles 84 against the top wall of the first slide hole 81, so that the top ends of the four ejector rods 52 are respectively inserted into the four second slots 513.

[0051] When the mold is closed, the injection molding machine controls the movable template 13 to move toward the fixed template 12. During this process, the four ejector rods 52 will be inserted into the four insertion holes 511 and push the four sliders 51 to move toward the molding insert 2. The movement of the four sliders 51 will drive the eight molding rods 22 to move. At the same time, the four inserts 83 will be pressed into the second sliding holes 82, and the four springs 85 will be compressed.

[0052] When the mold is finally fully closed, the four sliders 51 will be located in the four receiving grooves 121, the four first inclined surfaces 514 will fit the four second inclined surfaces 122, the four first slots 512 will align with the four second slide holes 82, the four springs 85 will press the four annular baffles 84 against the top wall of the first slide hole 81, the top ends of the four ejector rods 52 will be inserted into the four first slots 512 respectively, and the ends of the eight molding rods 22 away from the corresponding sliders 51 will pass through the eight through holes 71 and move to the predetermined position. After the mold is fully closed, the injection molding machine injects hot melt plastic into the first molding area 3 through the first channel 41 and the four second channels 42.

[0053] After the handle bodies 9 are cooled after injection molding, the injection molding machine controls the movable template 13 to move away from the fixed template 12. Under the action of the ejector pin 52, the force of the movement of the fixed template 12 is converted into the force of the movement of the four sliders 51, so that the four sliders 51 move, thereby driving the eight molding rods 22 to move away from the eight handle bodies 9, and finally making the eight molding rods 22 escape from the sixteen mounting holes 93 of the eight handle bodies 9, and the top ends of the four ejector pins 52 are inserted into the four first slots 512.

[0054] Then the injection molding machine controls the two top plates 15 to move toward the movable mold plate 13. When the two top plates 15 move, they will drive a number of ejector pins 16 and a number of pulling rods to move, thereby ejecting eight handle bodies 9 and injection molding waste from the molding insert 2, thereby completing the production demoulding of a group of handle bodies 9.

[0055] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
