Description

TECHNICAL FIELD

[0001] The utility model relates to injection molding internal cutting technical field especially relates to a kind of internal cutting structure of injection mold for packing bottle. BACKGROUND

[0002] Injection internal cutting is a special process for cutting or processing inside product during injection molding, it is usually before injection part has not been completely cooled solidification, using special cutting tool or mechanism, from injection mold internal product is cut, punched, grooving etc.

[0003] Packing bottle is generally composed of bottle body and bottle cap, and bottle cap injection molding can be injected in multiple ways, but the feed channel connecting main runner and cavity of traditional injection mold for packing bottle forms water gate waste, and water gate waste is connected with bottle cap, needs subsequent shearing, it is more time wasting, affect production efficiency, therefore a kind of internal cutting structure of injection mold for packing bottle is needed;

[0004] For example: bottle cap injection molded part is small in size, and multiple, workers need to spend a lot of time to trim water gate one by one, this process is not only inefficient, and it is easy to cause trimming quality to be uneven due to operation fatigue, one worker works 8 hours a day, can only trim several thousand water gates of small injection molded parts, seriously limit the overall production progress of product.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A kind of internal cutting structure of injection mold for packing bottle, including rack and the fixed template located at the top of the rack, further include:

[0008] Separation mechanism is used for separating bottle cap and water gate waste;

[0009] The outer wall of one side of the fixed template is provided with a fixed module, the outer wall of one side of the fixed module is provided with a cavity, the outer wall of one side of the fixed module is provided with a first sliding groove and a second sliding groove, the inner wall of the second sliding groove is provided with a third sliding groove, the inside of the fixed template is provided with a cavity, the inner wall of the cavity is connected with a movable rod through a hinge, the outer wall of both ends of one side of the movable rod is connected with a mounting bracket and a connecting rod through a hinge, a plurality of cutters are installed on the outer wall of one side of the mounting bracket, the outer wall of the cutter is provided with an opening, and the outer wall of the connecting rod is sleeved with a stop block and a return spring.

[0010] In the scheme, before the mold is closed, the cutter blocks the cavity feeding channel. When the mold is closed, the movable module on the other side is used to press the cutter, so that the cutter is retracted, so that the opening coincides with the cavity feeding channel, and the feeding channel is connected. Therefore, the injection can be carried out. Before the injection part is completely cooled and solidified, the demolding mechanism is used to slightly separate the fixed module and the movable module on the other side under the premise of ensuring that the mold is closed, so that the cutter is not pressed. Therefore, under the action of the return spring, the cutter returns to the original position, the cavity feeding channel (the connecting part of the bottle cap and the water outlet) is cut off, so that the bottle cap and the water outlet waste are separated. After the injection part is completely cooled, demolding can be carried out, and subsequent cutting of the water outlet waste and the bottle cap is not required, time is saved, and production efficiency is improved.

[0011] In a preferred scheme, the separation mechanism includes a square groove opened in the outer wall of the top of the rack, a guide plate is installed on the inner wall of the square groove, a plurality of screen grooves are opened in the top outer wall of the guide plate, and the bottom inner wall of the rack is provided with two storage boxes. The positions of the two storage boxes correspond to the bottom position of the guide plate and the position below the screen groove, respectively.

[0012] After demolding, the water outlet waste is mixed with the bottle cap of the packaging bottle, and manpower is wasted for sorting. Therefore, the separation mechanism is additionally arranged on the rack, the water outlet waste is intercepted by the screen groove on the guide plate, and the bottle cap falls from the screen groove into the storage box at the bottom of the screen groove. The water outlet waste is collected into another storage box, time is saved, and production efficiency is further improved.

[0013] As known from the above, the inner cutting structure of the injection mold for packaging bottles comprises a rack and a fixed template located at the top of the rack, and further comprises:

[0014] A separation mechanism is used to separate the bottle cap and the water outlet waste.

[0015] The outer wall of one side of the fixed template is provided with a fixed module, the outer wall of one side of the fixed module is provided with a cavity, the outer wall of one side of the fixed module is provided with a first sliding groove and a second sliding groove, the inner wall of the second sliding groove is provided with a third sliding groove, the inside of the fixed template is provided with a cavity, the inner wall of the cavity is connected with a movable rod through a hinge, the outer wall of both ends of one side of the movable rod is connected with a mounting bracket and a connecting rod through a hinge, the outer wall of the mounting bracket is provided with a plurality of cutters, the outer wall of the cutter is provided with an opening, and the outer wall of the connecting rod is sleeved with a stop block and a return spring.
