Description

Technical Field

[0001] The utility model relates to the technical field of plastic cup injection molding, and more specifically, it relates to a plastic cup injection molding machine. Background Art

[0002] Degradable plastic cups refer to plastic cups that can be degraded into environmentally friendly substances under natural environmental conditions after use. The processing of plastic cups requires the use of injection molding devices. The existing injection molding devices need to wait until the product is completely cooled before demolding. During the cooling process, the injection molding head needs to stop molding and wait until the plastic cup is cooled and demolded before continuing processing, resulting in low plastic cup molding efficiency.

[0003] Therefore, a solution needs to be proposed to solve this problem. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a plastic cup injection molding machine, which drives two processing tables to move through a mounting frame, so that when the processing table on one side is cooling, the lower mold base on the processing table on the other side can carry out the next injection molding process, thereby improving the efficiency of plastic cup molding.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a plastic cup injection molding machine, including a frame, the frame including two symmetrically arranged fixed plates, a mounting frame slidably connected to the fixed plates on both sides is arranged, two processing tables are fixedly connected to the mounting frame, and lower mold seats are arranged on the processing tables. A support frame is installed above the frame, and an injection molding area and cooling areas on both sides of the injection molding area are arranged on the support frame. A lifting device for driving the cooling area to rise and fall is arranged between the cooling area and the support frame.

[0006] By adopting the above technical scheme, when the plastic cup needs to be injection molded, the processing table on one side will be located at a position corresponding to the injection molding area, and the lower mold base and the injection head on the injection molding area can perform injection molding. After the injection molding is completed, the mounting frame is moved so that the processing table on the other side comes to the position corresponding to the injection molding area for the next round of injection molding, and the lower mold base that has just completed the injection molding will move to the position corresponding to the cooling zone. At this time, the cooling zone is moved down to cool and demold the plastic cup in the lower mold base. After the injection molding is completed, the cooling and demolding will also be completed. At this time, the mounting frame is moved in the opposite direction again, and the vacant lower mold base after demolding will come to the injection molding area again for injection molding, and the lower mold base after injection molding will move to the cooling zone on the other side for cooling and demolding. In this reciprocating cycle, the injection molding of the plastic cup can be performed uninterruptedly, making the processing of the plastic cup more efficient.

[0007] The utility model is further configured as follows: a groove is provided on one side of the fixing plate close to the mounting frame, a driving gear rotatably connected thereto is provided on the inner wall of the groove, a driving member for driving the driving gear to rotate is installed on the fixing plate, a moving rod is slidably connected to the inner wall of the groove, a plurality of latching teeth meshing with the driving gear are provided on the side of the moving rod close to the driving gear, and the moving rod is fixedly connected to the mounting frame.

[0008] By adopting the above technical solution, when the mounting frame needs to be moved, the driving gear is driven to rotate by the driving member 1. Since the moving rod is provided with a latching tooth, after the driving gear rotates, it can drive the moving rod to move. After the moving rod moves, it can drive the mounting frame and the processing table to move. After moving to the appropriate position, the driving member 1 is closed to make the mounting frame stay at the current position. The reciprocating movement of the mounting frame can be completed by rotating the driving gear forward and backward, which is easy to operate.

[0009] The utility model is further configured as follows: a receiving groove is provided on one side of the fixing plate close to the mounting frame, a screw rod rotatably connected thereto is provided on the inner wall of the receiving groove, a driving member 2 for driving the screw rod to rotate is installed on the fixing plate, a nut seat is sleeved on the screw rod, and the nut seat is fixedly connected to the mounting frame.

[0010] By adopting the above technical solution, when it is necessary to drive the mounting frame to move, the screw rod is driven to rotate by the driving member 2. After the screw rod rotates, the mounting frame can be driven to move through the nut seat. After the mounting frame moves to a suitable position, the screw rod can be stopped. The nut seat and the mounting frame can be driven to reciprocate by rotating the screw rod forward and backward, which is easy to operate.

[0011] The utility model is further configured as follows: a limiting rod is arranged on the inner wall of the accommodating groove, and a limiting groove for the limiting rod to pass through is arranged on the nut seat.

[0012] By adopting the above technical solution, when the nut seat moves along with the rotation of the screw rod, the nut seat will move along the limiting rod, so that the nut seat is more stable during the movement.

[0013] The utility model is further configured as follows: a plurality of array-distributed universal balls are arranged on the inner wall of the limiting groove, and the universal balls are fitted with the surface of the limiting rod.

[0014] By adopting the above technical solution, when the nut seat moves along the limit rod, the universal ball will roll along the surface of the limit rod, reducing the friction between the limit rod and the limit groove, making the movement of the nut seat smoother.

[0015] The utility model is further configured as follows: an extension portion is fixedly connected to one side of the mounting frame away from the groove, and a movable groove for the extension portion to extend and move is arranged on the fixing plate on the other side.

[0016] By adopting the above technical solution, during the movement of the mounting frame, the extension portion will be inserted into the moving groove and move, so that the mounting frame is more stable during the movement.

[0017] The utility model is further configured as follows: the cooling zone includes an outer shell, a plurality of array-distributed cooling fans are arranged on the inner wall of the outer shell, the lifting device includes a cylinder, one end of the cylinder is fixedly connected to the mounting frame, and the output end of the cylinder is fixedly connected to the upper end surface of the outer shell.

[0018] By adopting the above technical solution, when the plastic cup molded in the lower mold base needs to be cooled, the outer shell is driven downward by extending the cylinder so that it covers the outside of the lower mold base, and then the plastic cup in the lower mold base is cooled by the air cooler in the outer shell. After cooling, the outer shell is driven upward by shortening the cylinder to facilitate demolding and unloading of the cooled plastic cup.

[0019] In summary, the utility model has the following beneficial effects:

[0020] The utility model drives two processing tables to move by means of a mounting frame, so that when the processing table on one side is cooling, the lower die seat on the processing table on the other side can perform the next injection molding process, thereby improving the efficiency of plastic cup molding.
