Description

Technical Field

[0001] The utility model relates to the field of plastic bottle production, in particular to a mechanism for forming a handle embedding position and a plastic bottle mold using the mechanism. Background Art

[0002] In daily life, plastic bottles for liquids such as water and oil are widely used in consumers' daily life, which greatly facilitates people's lives. For plastic bottles of 5 liters or more, due to their heavy weight, handles are usually set on the side of the bottle for easy carrying. At present, most of the handles used on existing plastic bottles are formed by another process and then embedded in the plastic bottle after the blow molding stage of the plastic bottle is completed.

[0003] When the plastic bottle is formed, the blank of the bottle body will push the handle part to the inner wall of the mold under the action of compressed air, and finally stick to the mold together with the blank of the handle part under the action of compressed air; in the prior art, an embedding position for embedding the handle is formed on the bottle body through the cooperation of the mold structure and compressed air. However, the above structure makes it difficult to separate the formed plastic bottle from the mold. If it is forcibly removed, the bottle body is easily deformed, resulting in low demoulding efficiency of the plastic bottle, which leads to reduced production efficiency of plastic bottles with embedding positions.

[0035] Please refer to Figures 1 to 6 The utility model provides a mechanism for forming a handle embedding position, comprising a support 1, a guide plate 2, a drive assembly 3, a first sliding block 4 and a second sliding block 5;

[0036] The support 1 is provided with a sliding groove 101 along the X-axis direction, and the support 1 is provided with a guide plate through hole 102 along the Y-axis direction, and the sliding groove 101 is connected with the guide plate through hole 102;

[0037] The first sliding block 4 and the second sliding block 5 are slidably assembled in the sliding slot 101 respectively; the first sliding block 4 is provided with a first guide rod 41 on the side facing the guide plate through hole 102, and a first embedded plate 42 is provided on the side facing the opening of one end of the sliding slot 101; the second sliding block 5 is provided with a second guide rod 51 on the side facing the guide plate through hole 102, and a second embedded plate 52 is provided on the side facing the opening of the other end of the sliding slot 101;

[0038] The guide plate 2 is slidably assembled in the guide plate through hole 102, and the guide plate 2 is provided with a first long circular arc hole 201 and a second long circular arc hole 202. The first guide rod 41 passes through the sliding through groove 101 and extends into the first long circular arc hole 201; the second guide rod 51 passes through the sliding through groove 101 and extends into the second long circular arc hole 202.

[0039] The driving end of the driving assembly 3 is connected to one end of the guide plate 2, driving the guide plate 2 to move along the Y-axis direction, and through the cooperation of the first long circular arc hole 201 and the first guide rod 41, the first sliding block 4 slides in the sliding groove 101 along the X-axis direction, and through the cooperation of the second long circular arc hole 202 and the second guide rod 51, the second sliding block 5 slides in the sliding groove 101 along the X-axis direction.

[0040] The mechanism for forming a handle embedding position is applied to a plastic bottle mold 6. The support 1, the guide plate 2, the drive assembly 3, the first sliding block 4 and the second sliding block 5 cooperate to realize the movement of the first embedding plate 42 and the second embedding plate 52 extending or retracting from the sliding groove 101, so that the first embedding plate 42 and the second embedding plate 52 extend from the sliding groove 101 during the blow molding process to form a handle embedding position on the bottle body, and retract into the sliding groove 101 after the blow molding is completed; the first embedding plate 42 and the second embedding plate 52 are prevented from interfering with the handle embedding position, thereby avoiding the problem of difficulty in separating the molded plastic bottle from the mold, reducing the difficulty of removing the plastic bottle from the mold, and improving the demolding efficiency of the plastic bottle.

[0041] The first long circular arc hole 201 and the second long circular arc hole 202 play a guiding role. When blow molding is performed, the driving end of the driving assembly 3 drives the guide plate 2 to move forward along the Y-axis direction, and the first long circular arc hole 201 and the first guide rod 41 cooperate to drag the first sliding block 4, so that the first sliding block 4 slides along the X-axis direction in the sliding groove 101; at the same time, the second long circular arc hole 202 and the second guide rod 51 cooperate to drag the second sliding block 5, so that the second sliding block 5 slides along the X-axis direction in the sliding groove 101, so that the first sliding block 4 and the second sliding block 5 move away from each other, driving the first embedded plate 42 to extend from one end opening of the sliding groove 101, and driving the second embedded plate 52 to extend from the other end opening of the sliding groove 101. When the first embedded plate 42 and the second embedded plate 52 extend, a handle embedding position is formed at the corresponding position of the plastic bottle, which is convenient for the subsequent installation of the handle.

[0042] After the blow molding is completed, the driving end of the driving assembly 3 drives the guide plate 2 to move in the opposite direction along the Y-axis, and the first long arc hole 201 and the first guide rod 41 cooperate to drag the first sliding block 4, so that the first sliding block 4 slides in the opposite direction along the X-axis in the sliding groove 101; at the same time, the second long arc hole 202 and the second guide rod 51 cooperate to drag the second sliding block 5, so that the second sliding block 5 slides in the opposite direction along the X-axis in the sliding groove 101, so that the first sliding block 4 and the second sliding block 5 approach each other, drive the first embedded plate 42 to retract from one end opening of the sliding groove 101, and drive the second embedded plate 52 to retract from the other end opening of the sliding groove 101. When the first embedded plate 42 and the second embedded plate 52 are retracted, there is no interference between the first embedded plate 42, the second embedded plate 52 and the bottle body, which is convenient for removing the plastic bottle 7.

[0043] Specifically, the support 1 includes a first shell 11, a second shell 12 and a connecting bottom plate 13; the first shell 11 and the second shell 12 are bilaterally symmetrical with the X-axis direction as the symmetry axis; a first groove 111 is provided on the inner side of the first shell 11, a first through hole 112 is opened on one side of the first groove 111, and the first groove 111 is connected to the first through hole 112; a second groove is provided on the inner side of the second shell 12, a second through hole is opened on one side of the second groove, and the second groove is connected to the second through hole;

[0044] The first shell 11 and the second shell 12 are detachably connected to form a support plate; the first groove 111 and the second groove cooperate to form a sliding groove 101, and the first through hole 112 and the second through hole cooperate to form a guide plate through hole 102;

[0045] One side of the support plate is detachably connected to the connecting bottom plate 13 , and the shape of the side wall of the other side of the support plate is adapted to the shape of the body of the plastic bottle 7 .

[0046] The connecting bottom plate 13 is used to connect with the plastic bottle mold 6, so as to fix the whole structure. The shape of the side wall of the other side of the support plate is adapted to the shape of the bottle body of the plastic bottle 7, so that the plastic bottle 7 embryo can form a corresponding shape during blow molding.

[0047] Specifically, the first long circular arc hole 201 and the second long circular arc hole 202 are bilaterally symmetrical with the axis of the guide plate 2 in the X-axis direction as the symmetry axis.

[0048] In a specific embodiment of the present invention, the first shell 11 and the second shell 12 are symmetrical with the X-axis direction as the symmetry axis, so that the extension distances of the first embedding plate 42 and the second embedding plate 52 are the same, so that the depths of the handles at both ends of the bottle body are the same.

[0049] When the depth of the handle embedding position needs to be adjusted, the distance between the first oblong arc hole 201 and the second oblong arc hole 202 can be changed according to actual conditions.

[0050] Furthermore, the driving assembly 3 includes a driving device 31 and a connecting member 32;

[0051] The connecting member 32 is sleeved on the driving end of the driving device 31 , and is connected to a side of the guide plate 2 away from the sliding groove 101 ; the guide plate through hole 102 is provided with an avoidance area 103 adapted to the shape of the connecting member 32 .

[0052] The driving device 31 drives the guide plate 2 to move along the Y-axis direction through the connecting member 32. With the above structure, the transmission process of the driving device 31 can be made more stable. The avoidance area 103 plays a role in preventing the connecting member 32 from interfering with the support plate.

[0053] Furthermore, the driving assembly 3 further comprises a connecting block 33 ; the connecting block 33 is detachably connected to the plastic bottle mold 6 ; the pipeline of the driving device 31 passes through the connecting block 33 and is connected to the outside.

[0054] In a specific embodiment of the present invention, the driving device 31 is a cylinder, and the pipeline of the driving device 31 passes through the connecting block 33 and is connected to an external air source.

[0055] The connecting block 33 serves to fix the driving device 31, and is provided with a connecting pipeline. The pipeline of the driving device 31 is connected to the external gas source through the connecting pipeline, so that the driving device 31 can receive the gas discharged or filled in by the external gas source, thereby achieving the purpose of controlling the driving end of the driving device 31 to extend or retract.

[0056] Preferably, rollers 104 are rotatably mounted on the outer circumferences of the first guide rod 41 and the second guide rod 51 .

[0057] By adopting the above structure, the friction between the first guide rod 41 and the side wall of the first long arc hole 201, and the friction between the second guide rod 51 and the side wall of the second long arc hole 202 can be reduced, so that the sliding process of the first sliding block 4 and the second sliding block 5 is smoother, and the first sliding block 4 and the second sliding block 5 are prevented from getting stuck during sliding, resulting in deformation of the handle embedding position of the bottle body, and the first embedding plate 42 and the second embedding plate 52 are prevented from being unable to extend due to the jamming of the first sliding block 4 and the second sliding block 5, resulting in the inability to form a handle embedding position.

[0058] The utility model also provides a plastic bottle mold, which uses the above-mentioned mechanism for forming a handle embedding position.

[0059] The mechanism for forming a handle embedding position is applied to a plastic bottle mold. The support 1, the guide plate 2, the driving assembly 3, the first sliding block 4 and the second sliding block 5 cooperate to realize the movement of the first embedding plate 42 and the second embedding plate 52 extending or retracting from the sliding groove 101. After the handle embedding position is formed on the bottle body, the first embedding plate 42 and the second embedding plate 52 are both retracted into the sliding groove 101; the first embedding plate 42 and the second embedding plate 52 are prevented from interfering with the handle embedding position, thereby avoiding the problem of difficulty in separating the molded plastic bottle 7 from the mold, reducing the difficulty of removing the plastic bottle 7 from the mold, and improving the demolding efficiency of the plastic bottle 7.
