Description

Technical Field

[0001] The utility model relates to a plastic product forming machine. Background Art

[0002] The plastic product molding machine has a main frame frame, which is used to install a heating device (for heating sheets), a sheet feeding chain rail (for conveying sheets), a molding mechanism (for molding plastic products), etc., so that they can be moved, transported and placed together with the main frame frame. The main frame frame can be connected by welding to form a main structure. This relatively long and large main structure of the main frame frame is not only difficult to ensure the processing accuracy, but also easy to generate heat during welding, causing the main frame frame to have a slight deformation (especially the main frame frame containing steel pipes and other pipes is more susceptible to heat deformation); for the heating device, the sheet feeding chain rail, etc., the accuracy and slight deformation will not affect; but for the molding mechanism, this accuracy and slight deformation are enough to affect the molding.

[0003] The molding mechanism has an independent molding body, on which a plurality of columns (i.e. guide columns) are installed, on which an upper mold seat that can be adjusted up and down is installed, and the molding body is forcibly locked on the main frame frame by fasteners for fixed connection (relative position locking, rigid connection), and the main frame frame directly carries the molding body and the entire molding mechanism, and the molding mechanism is connected to the main frame frame through the molding body, and the entire molding mechanism (including the molding body) is moved, transported and placed in the factory for production use with the main frame frame;

[0004] However, if the main frame rack is processed with low precision or is slightly deformed, the positions on the main frame rack for connecting the molding body (such as the front, rear, left and right installation positions) cannot remain relatively consistent with each other. The molding body is forcibly locked to the main frame rack by fasteners, resulting in slight deformation of the molding body, causing the columns to be slightly skewed (the columns are not parallel to each other), and the upper mold base cannot be adjusted up and down on the columns (stuck or suffocated). After this happens, the equipment manufacturer needs to go to the customer's factory to remove the columns, and reinstall the columns and other parts on the columns, which is very troublesome. In addition, the molding mechanism also has an upper mold and a lower mold for opening and closing the mold. The upper mold is set on the upper mold base. Slight deformation of the molding body will also affect the smooth closing of the upper and lower molds, affecting the molding effect of the plastic product and the life of the mold.

[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the implementation of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field without making creative work based on the embodiments of the utility model are within the scope of protection of the utility model.

[0030] Referring to the accompanying drawings, in the embodiment of the present embodiment, the supporting device of the plastic product molding machine includes a main frame frame 40 and a molding body 42 of a molding mechanism 41; a column 3 is provided on the molding body 42, and the column 3 is used for the upper mold base 2 to be installed and connected. The upper mold base 2 can be raised and lowered on the column 3 (i.e., the guide column) to adjust the upper and lower positions; the molding body 42 is installed on the main frame frame 40 through a first fastener, and the molding body 42 is connected to the main frame frame 40 by the first fastener, and the molding body 42 can be transported with the main frame frame 40;

[0031] Among them, the molding body 42 is also provided with a floor support assembly 44, and the molding body 42 can contact the (factory) ground through the floor support assembly 44. When in use, the molding body 42 is directly supported by the ground, and the molding operation is more stable; at least three groups of floor support assemblies 44 are provided, and the support stability is relatively higher; the molding body 42 has a floor connection part 45, and the floor connection part 45 is correspondingly arranged above the floor support assembly 44, and the molding body 42 is supported by its floor connection part 45 placed on the floor support assembly 44; the floor support assembly 44 includes a floor support grounding block 46, and the floor support grounding block 46 can touch the ground The upper and lower spacing between the floor support grounding block 46 and the floor connection part 45 of the molded fuselage 42 can be adjusted. By adjusting the upper and lower spacing between the floor support grounding block 46 and the floor connection part 45, each floor support component 44 can adjust the inclination, horizontal position, and height position of the molded fuselage 42 (i.e., the floor adjustment of the molded fuselage 42) when cooperating with the floor support molded fuselage 42, and can adapt to the ground environment, so that the molded fuselage 42 can be stably and smoothly landed and supported by the ground. The molded fuselage 42 is stable and avoids swinging and shaking. In the factory, the molded fuselage 42 does not need to be loaded on the main frame rack 40 and is not easily affected by the main frame rack 40.

[0032] In the supporting device of the plastic product molding machine, the molding body 42 can directly fall to the ground and contact the ground through the floor support assembly 44 in the factory, and the molding body 42 is supported by the ground. The molding body 42 does not need to be loaded on the main frame rack 40, and the molding operation is more stable; the molding body 42 can fall to the ground through the floor support assembly 44 and be supported by the ground. There is no need for the main frame rack 40 to support the molding body 42. When the molding body 42 and the main frame rack 40 are connected by the first fastener, there is no need to forcibly lock (lock). It only needs to be connected by the first fastener so that the molding body 42 can be carried with the main frame rack 40. In the factory and during the molding process, the molding body 42 directly falls to the ground without the need for the main frame rack 40 to support the load. When the first fastener is connected, there is no need to forcibly lock (lock), so that the molding body 42 will not be affected by the low processing accuracy or slight deformation of the main frame rack 40, and the molding body 42 will not be deformed, the column 3 will not be skewed, and the molding mold will not be affected.

[0033] The following optimization or further explanation may be performed based on the above embodiments.

[0034] For example, the ground support assembly 44 includes a ground support grounding block 46, and the ground support assembly 44 also includes a support top block 47 and a spacing adjustment wedge 48. The support top block 47 is located above the ground support grounding block 46, and the support top block 47 is located below the ground connection portion 45 of the molded fuselage 42. The spacing adjustment wedge 48 is arranged between the ground support grounding block 46 and the support top block 47. The ground support assembly 44 will form a wedge-shaped spacing adjustment structure, and the spacing adjustment wedge 48 can be provided with a wedge surface adjustment structure on one side or on both sides. The spacing adjustment wedge 48 is moved and adjusted between the ground support grounding block 46 and the support top block 47, and the spacing between the ground support grounding block 46 and the support top block 47 is adjusted, so that the upper and lower spacing between the ground support grounding block 46 and the ground connection portion 45 of the molded fuselage 42 can be adjusted.

[0035] For example, the spacing adjustment wedge 48 is a wedge frame, which can be a square frame structure, and the middle of the wedge frame is an avoidance channel 49 that runs through from top to bottom; the upper side of the spacing adjustment wedge 48 is a first wedge surface 50, and the lower side of the spacing adjustment wedge 48 is a second wedge surface 51; a rotation adjustment screw 52 is provided on the spacing adjustment wedge 48 (such as the wedge frame), and the relative axial position of the rotation adjustment screw 52 and the spacing adjustment wedge 48 (such as the wedge frame) remains unchanged, that is, the rotation adjustment screw 52 can rotate on the spacing adjustment wedge 48 (such as the wedge frame), and the rotation adjustment screw 52 and the spacing adjustment wedge 48 (such as the wedge frame) move axially together (the relative axial position remains unchanged), and the axial position refers to the axial position of the rotation adjustment screw 52; a vertical guide shaft 53 is provided in the avoidance channel 49 , a horizontal threaded transmission hole 54 is provided on the vertical guide shaft 53, and the rotary adjustment screw 52 is connected to the horizontal threaded transmission hole 54 for transmission. When the rotary adjustment screw 52 rotates (forward or reverse), it cooperates with the horizontal threaded transmission hole 54 on the vertical guide shaft 53, so that the rotary adjustment screw 52 axially advances or retreats, and the spacing adjustment wedge 48 (such as a wedge block frame) will also advance or retreat together; a first inclined surface 55 is provided on the lower side of the support top layer block 47, and a first limiting guide hole 56 is provided on the support top layer block 47. The ground support grounding block 46 includes a lower inclined plate 57, and a second inclined surface 58 is provided on the upper side of the lower inclined plate 57. A second limiting guide hole 59 is provided on the lower inclined plate 57. The spacing adjustment wedge 48 is sandwiched between the support top layer block 47 and the lower inclined plate 57, so that the spacing The adjusting wedge block 48 can move smoothly and stably (forward or backward) driven by the rotating adjusting screw 52, ​​the first inclined surface 55 and the first wedge surface 50 are in close contact and sliding cooperation (their inclination angles can be consistent), and the second wedge surface 51 and the second inclined surface 58 are in close contact and sliding cooperation (their inclination angles can be consistent), forming an upper and lower double-sided adjustment structure of the spacing adjustment wedge block 48. In the process of axially advancing or retreating the spacing adjustment wedge block 48 (such as the wedge block frame) together with the rotating adjusting screw 52, ​​the upper and lower spacing between the supporting top layer block 47 and the ground supporting grounding block 46 (such as the lower inclined plate 57) can be adjusted. The structure is relatively compact and the adjustment range can be larger. The upper end of the vertical guide shaft 53 is matched with the first limit guide hole 56. The lower end of the shaft 53 is arranged in the second limit guide hole 59, so that during the adjustment process, the two ends of the vertical guide shaft 53 can cooperate to limit in the first limit guide hole 56 and the second limit guide hole 59, and can support the horizontal threaded transmission hole 54 on the vertical guide shaft 53 to cooperate with the rotation adjustment screw 52 for transmission. In addition, in the process of the spacing adjustment wedge block 48 (such as the wedge block frame) moving forward or backward axially with the rotation adjustment screw 52, ​​the wedge block is added with an upper and lower double-sided adjustment structure, and the spacing adjustment wedge block 48 (such as the wedge block frame) and the rotation adjustment screw 52 will also be additionally lifted and lowered. The vertical guide shaft 53 (and its horizontal threaded transmission hole 54) can be lifted and lowered in situ by the first limit guide hole 56 and the second limit guide hole 59 in cooperation with the limit guide, and cooperate with the rotation adjustment screw 52 to operate.In the structure of the floor support assembly 44, the upper and lower spacing between the floor support grounding block 46 and the floor connection part 45 of the molded fuselage 42 can be adjusted by rotating the rotary adjustment screw 52. The operation is stable and simple. The floor support assembly 44 is not only compact in structure, but also has a relatively larger adjustment spacing range.

[0036] Further optimization, the ground connection part 45 and the ground support ground block 46 are connected by a second fastener 60 with a loose lock, wherein the second fastener 60 passes through the avoidance channel 49, and the spacing adjustment wedge 48 (such as a wedge frame) moves forward or backward without interfering with the second fastener 60. The ground support ground block 46 also includes a contact plate 61, which is located below the lower inclined plate 57. The ground support ground block 46 contacts the ground through the contact plate 61, and the contact plate 61 and the lower inclined plate 57 are integrally or separately arranged; the split arrangement is adopted in the figure, which is not only convenient for processing and maintenance, but also can use different materials.

[0037] In addition, the first inclined surface 55 and the second inclined surface 58 are arranged in mirror symmetry up and down, the first wedge surface 50 and the second wedge surface 51 are arranged in mirror symmetry up and down, the upper and lower forces are balanced, and the spacing adjustment wedge block 48 operates stably; a first through hole is provided on the ground connection part 45, a second through hole is provided on the supporting top layer block 47, and a third through hole is provided on the lower inclined plate 57. In the figure, the lower inclined plate 57 and the contact plate 61 are separately arranged, and the second fastener 60 passes through the first through hole, the second through hole, the avoidance channel 49, and the third through hole and is connected to the contact plate 61. In the figure, the second fastener 60 passes through the first through hole, the second through hole, the avoidance channel 49, and the third through hole in sequence and is connected to the contact plate 61. A through hole can also be provided on the contact plate 61 for the second fastener 60 to be connected; wherein, the upper end of the second fastener 60 (such as a connecting bolt) is provided with a locking nut 6 5. The locking nut 65 is located above the ground connection part 45. By loosening and tightening the locking nut 65, the ground connection part 45 and the ground support grounding block 46 are connected by the second fastener 60. After the locking nut 65 is loosened, the spacing adjustment wedge block 48 can be smoothly moved and adjusted. After the adjustment is completed, the locking nut 65 is locked and fixed in position to clamp the ground support assembly 44 (support top layer block 47, spacing adjustment wedge block 48, ground support grounding block 46). In addition, the ground support assembly 44 can be connected to the molded fuselage 42 through the second fastener 60, and can be carried and moved together with the molded fuselage 42; for example, the ground connection part 45 includes a ground connection plate, the first through hole can be opened on the ground connection plate, and the ground connection part 45 is mounted on the ground support assembly 44 to cooperate with the ground support.

[0038] A slide guide pair 66 may be provided between the first inclined surface 55 and the first wedge surface 50, and a slide guide pair 66 may be provided between the second inclined surface 58 and the second wedge surface 51. The slide guide pair 66 cooperates with the inclined surface and the wedge surface to slide and guide, and the operation is stable. A first avoidance screw groove 67 is also provided on the first inclined surface 55, and the first avoidance screw groove 67 is correspondingly arranged with the rotation adjustment screw 52. A second avoidance screw groove 68 is also provided on the second inclined surface 58, and the second avoidance screw groove 68 is correspondingly arranged with the rotation adjustment screw 52. When the sizes of other components remain unchanged, a relatively large rotation adjustment screw 52 can be used, and the first avoidance screw groove 67 and the second avoidance screw groove 68 are used to avoid the position, so that the rotation adjustment screw 52 can be smoothly moved and operated in place. The rotation adjustment screw 52 has a relatively greater structural strength, is stable and not easy to break, and has a relatively compact structure. Among them, the axis of the rotation adjustment screw 52 is set horizontally.

[0039] For example, an assembly hole 69 is provided on the spacing adjustment wedge block 48 (such as a wedge block frame), and the assembly hole 69 is used for the installation of the rotation adjustment screw 52. The rotation adjustment screw 52 passes through the assembly hole 69. The rotation adjustment screw 52 adopts an adjusting bolt, and the bolt head 70 of the adjusting bolt is located on the outside of the assembly hole 69. A limit ring 71 (which can be connected with a pin) is also provided on the rotation adjustment screw 52. The limit ring 71 is located on the inner side of the assembly hole 69. The limit ring 71 and the bolt head 70 cooperate with the limit clamp on both sides of the assembly hole 69 of the spacing adjustment wedge block 48 (such as a wedge block frame); so that the rotation adjustment screw 52 can rotate on the spacing adjustment wedge block 48 (such as a wedge block frame), and the relative axial position of the rotation adjustment screw 52 and the spacing adjustment wedge block 48 (such as the wedge block frame) remains unchanged.

[0040] For example, a spherical concave-convex washer assembly 72 (including a spherical concave washer and a spherical concave washer) may be provided between the ground support assembly 44 and the ground connection part 45, so that when each group of ground support assemblies 44 adjusts the upper and lower spacing separately (such as the upper and lower spacing between the ground support grounding block 46 and the ground connection part 45 of the molded fuselage 42 is adjusted by the spacing adjustment wedge 48), the molded fuselage 42 can smoothly and stably adapt to the change of the overall position by its separate adjustment. For example, the spherical concave-convex washer assembly 72 is separately arranged on the upper side of the support top layer block 47 of the ground support assembly 44 and the lower side of the ground connection part 45; the spherical concave-convex washer assembly 72 is installed and connected to the upper side of the support top layer block 47 of the ground support assembly 44; the ground connection part 45 and the ground support grounding block 46 are also connected with a second fastener 60, and the second fastener 60 can also pass through the spherical concave-convex washer assembly 72 for connection without interference.

In the factory, after the molded fuselage 42 falls to the ground, the first fastener can also be used to connect the molded fuselage 42 with the main frame frame 40 additionally (without forcibly locking), and the molded fuselage 42 is not easy to shake during the molding process. For example, a reserved gap is left between the edge of the first connecting via 74 and / or the second connecting via and the corresponding first fastener passing through, and the reserved gap is allowed for the molded fuselage 42 to move relative to the main frame 40 (fine-tuning) so that the molded fuselage 42 can land, and can even allow the molded fuselage 42 to move forward, backward, left and right relative positions.
