Abstract
Description
Technical Field
[0001] This utility model relates to the field of blow molding machines, and in particular to a mold base drive adjustment mechanism for blow molding machines. Background Technology
[0002] During the operation of a blow molding machine, the mold base needs to be moved to meet continuous production requirements. The extruded preform falls into the mold for blow molding, while the mold base moves outward to open the mold and remove the blow-molded part, facilitating continuous extrusion of the preform.
[0003] The mold base is typically driven by a hydraulic cylinder, which also requires a hydraulic station, resulting in a large size and high cost. To reduce costs and space occupation, an electric motor can be used to drive the displacement of the mold base. In the prior art, utility model patent application number CN202221158468X discloses a dual-station electric mold opening and closing structure in a blow molding machine. When the second servo motor drives the cam to rotate, the cam can drive the mold moving linkage to reciprocate left and right. During the reciprocating motion of the mold moving linkage, it can drive the mold base to reciprocate left and right on the frame. However, it cannot adjust the endpoint position of the mold base movement, resulting in poor adaptability to blow molding dies and blow-molded product models, requiring improvement.

The mold base is laterally slidably mounted on the base. The guide seat is mounted on the base and located in front of the sliding path of the mold base. The motor mounting bracket is mounted on the guide seat. The servo motor is horizontally mounted on the motor mounting bracket and extends longitudinally. The first swing arm is vertically mounted on the rotating shaft of the servo motor. The second swing arm is located between the end of the first swing arm and the mold base. The adjustment seat is mounted on the base and located in front of or behind the guide seat. A baffle is provided on the adjustment seat. The adjustment screw is laterally mounted on the motor mounting bracket and vertically passes through the baffle. Nuts are provided on both sides of the baffle on the adjustment screw.
[0006] In a preferred embodiment of the present invention, the mold base is provided with a front template and a rear template that are longitudinally spaced apart.
[0007] In a preferred embodiment of the present invention, the mold base is provided with a hinge seat that is connected to the second swing arm.
[0008] In a preferred embodiment of the present invention, the bottom of the motor mounting bracket is provided with a horizontally extending guide groove, and the guide seat is provided with a guide key corresponding to the guide groove.

[0015] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0016] Please see Figures 1-2 The embodiments of this utility model include:
[0017] like Figure 1The blow molding machine mold base drive adjustment mechanism shown includes: base 1, mold base 2, servo motor 6, motor mounting bracket 3, first swing arm 9, second swing arm 8, guide seat 4, adjustment seat 13 and adjustment screw 15. The mold base 2 is slidably mounted on the base 1. A slide rail 5 located below the mold base 2 is provided on the base 1 to guide the lateral sliding of the mold base 2 and improve stability.
[0018] The mold base 2 is provided with a front template 10 and a rear template 11 that are longitudinally spaced apart. The blow molding mold is installed through the front template 10 and the rear template 11. The mold base 2 is usually equipped with a drive mechanism that drives the front template 10 and the rear template 11 to open and close the mold, thereby driving the opening and closing of the blow molding mold.
[0019] The guide seat 4 is placed on the base 1 and located in front of the sliding path of the mold base 2. The motor mounting bracket 3 is placed on the guide seat 4. The servo motor 6 is placed horizontally on the motor mounting bracket 3 and extends longitudinally. The first swing arm 9 is placed vertically on the rotating shaft of the servo motor 6. The servo motor 6 can be rotated by the PLC, which drives the first swing arm 9 to rotate at a certain angle.
[0020] The second swing arm 8 is positioned between the end of the first swing arm 9 and the mold base 2. In this embodiment, the mold base 2 is provided with a hinge seat 7 connected to the second swing arm 8, facilitating assembly. The second swing arm 8 and the first swing arm 9 are movably connected by a pin, allowing the included angle between the second swing arm 8 and the first swing arm 9 to be within a straight line (…). Figure 1 The conversion between the shape shown in the figure and the V-shape is performed to achieve the transverse movement drive of the mold base 2.
[0021] To adjust the endpoint position of the mold base 2's movement, the position of the servo motor 6 needs to be adjusted, which is also the position adjustment of the motor mounting bracket 3. For example... Figure 2 As shown, a horizontally extending guide groove 16 is provided at the bottom of the motor mounting bracket 3, and a guide key corresponding to the guide groove 16 is provided on the guide seat 4 for guiding the adjustment of the motor mounting bracket 3.
[0022] The adjusting seat 13 is mounted on the base 1 and located in front of or behind the guide seat 4. The adjusting seat 13 is fixed to the base 1 with screws, ensuring structural stability. A baffle 12 is provided on the adjusting seat 13, and the adjusting screw 15 is horizontally mounted on the motor mounting bracket 3 and vertically passes through the baffle 12. In this embodiment, the baffle 12 is provided with a through hole corresponding to the adjusting screw 15, facilitating assembly.
[0023] like Figure 2As shown, nuts 14 are provided on both sides of baffle 12 on the adjusting screw 15. The axial adjustment of the adjusting screw 15 is achieved by rotating the nuts 14, thereby changing the lateral position of the motor mounting bracket 3 on the base 1, and thus changing the end position of the mold base 2 on the base 1 to adapt to different blow molding molds and blow molded product models on the mold base 2.
[0024] In summary, the mold base drive adjustment mechanism for blow molding machines disclosed in this utility model is easy to operate, can drive the mold base to move laterally, and can adjust the end position of the mold base to move laterally on the base. It has a simple structure, high reliability, and wide applicability.
[0025] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
