Detailed Description
The utility model is further described below with reference to the accompanying drawings:
referring to fig. 1 to 3, the embodiment is illustrated by taking a three-color compression molding apparatus as an example, and includes a base 1, four vertical guide posts 11 are provided at four corners of the top surface of the base 1, four corners are slidably mounted on the vertical guide posts 11 through guide sleeves, a lower die holder 2 with a top surface for mounting a lower die 21, a hydraulic driving device 3 for driving the lower die holder 2 to lift, a fixed seat 4 fixed on the upper portion of the vertical guide posts 11, an upper die holder 5 with a top surface being limited by a bottom surface 41 of the fixed seat 4 and being laterally slidably mounted on the fixed seat 4, and three groups of upper dies 51 disposed on the bottom surface of the upper die holder 5 and distributed along the sliding direction thereof. The fixing seat 4 comprises a bottom surface 41 propped against the top surface of the upper die seat 5, and two opposite side plates 42 which extend vertically upwards from the bottom surface 41 and are distributed along the sliding direction of the upper die seat 5, a threaded sleeve 43 is fixedly arranged on one side plate 42 of the fixing seat 4 along the sliding direction of the upper die seat 5, a screw rod 52 penetrating through the threaded sleeve 43 in a threaded fit manner is arranged above the top surface of the upper die seat 5, a plurality of transverse guide posts 53 which are parallel to the screw rod 52 and are slidably penetrated on the side plates 42 of the fixing seat 4, and a motor driving device 54 for driving the screw rod 52 to move relative to the threaded sleeve 43, wherein the motor driving device 54 comprises a servo motor and a speed reducer.
The upper die holder 5 is driven by the screw rod 52, the transverse guide post 53 and the motor driving device 54 to transversely slide along the fixed seat 4, so that the upper die holder 5 can be accurately positioned at any position, and each upper die 51 is ensured to be accurately aligned with the lower die 21 respectively. The screw sleeve 43 is fixedly arranged on the fixed seat 4, the screw rod 52 is arranged on the upper die holder 5 to transversely move along with the upper die holder 5, and meanwhile, the top surface of the upper die holder 5 is limited by the bottom surface 41 of the fixed seat 4, so that the upper die holder can transversely slide, and the propping strength of the fixed seat 4 to the upper die holder 5 during die assembly can be ensured. If the conventional screw rod 52 is adopted, the screw sleeve 43 needs to be fixed with the upper die holder 5 and move transversely with the upper die holder 5, and the screw rod 52 is mounted and fixed on the fixing base 4, at this time, the fixing base 4 needs to be provided with a chute for the screw sleeve 43 to move transversely, that is, the fixing base 4 is divided into two parts, so that the strength of the fixing base 4 can not reach the requirement of impact strength in die assembly.
In this embodiment, a long sleeve 44 is concentrically fixed at one end of the threaded sleeve 43 away from the motor driving device 54, and the screw rod 52 is slidably mounted in the long sleeve 44. The long sleeve 44 is fixedly arranged at one end of the threaded sleeve 43, and the tail end of the screw rod 52 is slidably assembled in the long sleeve 44, so that compared with a traditional screw rod 52 mounting structure, a bearing seat at the tail end of the screw rod 52 can be omitted, the length of the screw rod 52 is further reduced, and the rigidity of the screw rod 52 is improved; the long sleeve 44 can also play a dustproof role on the screw rod 52, a longer dust cover is not required to be additionally arranged, in addition, the screw rod 52 has a better lubrication effect in a closed environment in the long sleeve 44, and the long-term running smoothness and reliability of the screw rod 52 are ensured. Because the tail end of the screw rod 52 is a relative free end, compared with the structure that two ends of the screw rod 52 are installed through bearing seats in the prior art, when the screw rod 52 or the threaded sleeve 43 slightly swings, the screw rod 52 and the threaded sleeve 43 cannot be easily blocked, and smooth and reliable sliding operation of the screw rod 52 is further ensured.
In this embodiment, the tail end of the screw rod 52 is sleeved with a copper sleeve 521 that is adapted to and slidingly engaged with the inner wall of the long sleeve 44. The copper sleeve 521 ensures the concentricity of the screw rod 52 in the long sleeve 44 and the smoothness of sliding, if abrasion occurs, the screw rod 52 can be replaced only by replacing the copper sleeve 521, and the replacement and maintenance are convenient.
In this embodiment, the screw thread outer diameter of the screw 52 is adapted to the inner diameter of the long sleeve 44. Namely, the gap between the outer wall of the screw rod 52 and the inner wall of the long sleeve 44 is very small, at the moment, the long sleeve 44 can support the screw rod 52, and the screw rod 52 and the like are easy to deform because the compression mold needs to be heated to a high temperature above 160 ℃ during working, at the moment, the long sleeve 44 can protect and support the screw rod 52, so that the screw rod 52 is prevented from deforming, and the transmission precision is ensured.
In this embodiment, the screw sleeve 43 is embedded and fixed on the side plate 42 of the fixing base 4 near the motor driving device 54, and when the motor driving device 54 approaches the screw sleeve 43, the screw rod 52 is accommodated in the long sleeve 44. At this time, not only the length of the screw rod 52 is shortened to the maximum extent and the rigidity thereof is ensured, but also the screw rod 52 is completely accommodated in the long sleeve 44 without providing a dust cover, and the optimum lubrication effect can be achieved.
In this embodiment, support slide rails 45 slidably engaged with the upper die holder 5 are further disposed on two sides of the fixing base 4 along the sliding direction of the upper die holder 5. The support slide rails 45 on both sides can further enhance the sliding stability of the upper die holder 5, and the support slide rails 45 can also be configured as roller tracks to reduce the sliding resistance.
The above description should not be taken as limiting the scope of the utility model, and any modifications, equivalent variations and modifications made to the above embodiments according to the technical principles of the present utility model still fall within the scope of the technical solutions of the present utility model.
