Description

Technical Field

[0001] The utility model relates to the technical field of mechanical moulds, in particular to a hydraulic lifting guide column component. Background Art

[0002] Guide pins are guiding elements used in combination with components in the mold to ensure that the mold can move with precise positioning and guide the mold stroke; hydraulic lifting guide pins use hydraulic power to perform telescopic movements. The guide pin assembly is mainly composed of a guide seat, a guide pin and a sliding sleeve, and the guide pin is used to slide up and down for lifting and guiding.

[0003] However, currently the guide post and the guide seat are lubricated by a ball sleeve, and a plurality of balls are embedded on the outside of the ball sleeve. The balls increase the sliding effect, and the reciprocating up and down movement increases the heat of the inner wall of the guide seat, and the guide seat expands due to the heat increase, which leads to a decrease in the skewness accuracy of the guide post; and there are gaps between the balls, and there are gaps between the ball sleeve and the guide seat. Impurities will be present inside after long-term use, thereby weakening the overall lubrication effect.

[0004] In order to solve the above problems, a hydraulic lifting guide column assembly is proposed in the present application. Utility Model Content

[0007] A further technical improvement of the utility model is that the linkage member includes a telescopic tube, the upper end of the telescopic tube is fixedly connected to the upper end of the ball sleeve, the upper end outer wall of the guide seat is fixedly connected with a fixing ring, and the lower end of the telescopic tube is fixedly connected to the upper end of the fixing ring.

[0008] A further technical improvement of the utility model is that a heat sink is fixedly connected to the inner side of the groove, the heat sink is located in the middle of the groove, and the length of the heat sink is smaller than the vertical length of the groove.

[0009] A further technical improvement of the utility model is that a partition is fixedly connected to the upper end of the groove, and the partition is provided with perforations, and the number of the perforations is set in multiples and is set at equal intervals.

[0010] A further technical improvement of the utility model is that the lower end surface of the fixing ring is arranged flush with the upper end surface of the heat sink.

[0011] A further technical improvement of the present invention is that the vertical cross section of the groove is arranged in a trapezoidal shape.

[0012] The embodiment of the utility model provides a hydraulic lifting guide column assembly, which has the following beneficial effects:

[0013] This new type is applied to the hydraulic lifting guide column assembly. By setting a linkage part, the guide column and the ball sleeve slide up and down. The friction heat is discharged through the linkage part, which can drive the internal air flow, thereby increasing the heat dissipation effect of the guide seat, and thus reducing the failure rate during use.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 A hydraulic lifting guide column assembly includes a guide seat 1, a ball sleeve 3 is slidably connected inside the guide seat 1, a guide column 2 is slidably connected inside the ball sleeve 3, a linkage piece is connected between the upper end of the ball sleeve 3 and the upper end of the guide seat 1, a groove 4 is opened on the upper end side wall of the guide seat 1, the groove 4 is set through the upper end of the guide seat 1, and the linkage piece is matched with the upper end of the groove 4.

[0023] Specific working principle and implementation method: After the guide seat 1, guide column 2 and ball sleeve 3 are slidably matched, a linkage piece is connected between the ball sleeve 3 and the guide seat 1, and a groove 4 is opened on the outer wall of the guide seat 1. The groove 4 can increase the overall heat dissipation of the guide seat 1, so that the overall heat dissipation during the lifting process is faster, and the thermal expansion of the guide seat 1 is reduced. The mutual cooperation between the linkage piece and the groove 4 can make the heat of the guide seat 1 dissipate faster, and further achieve the heat dissipation effect; the advantage of this design is that it can reduce the friction heat between the ball sleeve 3 and the guide seat 1 during the actual reciprocating lifting process, thereby reducing the thermal expansion coefficient of the guide seat 1, thereby making the overall lifting accuracy higher, and improving the use effect and service life.

[0024] like Figure 1 As shown, the linkage includes a telescopic tube 9, the upper end of the telescopic tube 9 is fixedly connected to the upper end of the ball sleeve 3, the upper end outer wall of the guide seat 1 is fixedly connected with a fixing ring 8, the lower end of the telescopic tube 9 is fixedly connected to the upper end of the fixing ring 8, the ball sleeve 3 moves with the up and down movement of the guide column 2, and the telescopic tube 9 is driven to stretch and contract when the ball sleeve 3 moves up and down. The protection of the telescopic tube 9 can prevent debris in the factory environment from entering between the guide seat 1 and the ball sleeve 3, thereby reducing usage failures.

[0025] like Figure 4 As shown, a heat sink 5 is fixedly connected to the inner side of the groove 4, the heat sink 5 is arranged in the middle of the groove 4, and the length of the heat sink 5 is set smaller than the vertical length of the groove 4, the heat sink 5 can increase the heat dissipation efficiency in the groove 4, and the heat conduction of the heat sink 5 can further improve the heat dissipation of the guide seat 1, and the up and down reciprocating extension and contraction of the telescopic tube 9 can stimulate the internal air flow, and the heat is blown out by the internally stimulated air, and the external air can be sucked in when stretching, thereby achieving the effect of heat exchange.

[0026] like Figure 4 As shown, a partition 6 is fixedly connected to the upper end of the groove 4, and a perforation 7 is provided on the partition 6. The number of the perforations 7 is multiple and the spacing is equal. The multiple perforations 7 provided on the partition 6 can filter impurities in the air, and the perforations 7 can increase the speed of air blowing and inhalation, thereby achieving a better blowing heat dissipation effect.

[0027] like Figure 1 and Figure 4As shown, the lower end surface of the fixing ring 8 is flush with the upper end surface of the heat sink 5, and the top of the heat sink 5 is flush with the lower end of the fixing ring 8 in order to enable better flow of internal air. The flowing air flows from the top of the heat sink 5, so that the heat on the surface of the heat sink 5 can be dissipated faster.

[0028] like Figure 4 As shown, the vertical cross-section of the groove 4 is set in a trapezoidal shape. The trapezoidal shape of the groove 4 can better dissipate heat, increase the contact area with the air, and thus achieve a better heat dissipation effect.
