Abstract
The utility model relates to a valve pin spacer. The valve pin spacer comprises a spacer body, wherein the spacer body is cylindrical; a circular groove is formed in the upper part of the spacer body; a valve pin hole for a valve pin to pass through is formed in the center of the bottom of the circular groove; two cup head screw holes are symmetrically formed in the two sides of the valve pin hole; the line of centers of the two cup head screw holes is a first radial line; a plurality of discharging grooves are formed in the wall of the circular groove along the circumferential direction; the center line of each discharging groove passes through the circle center of the circular groove; the line of centers of each discharging groove and each valve pin hole is a second radial line; the second radial line and the first radial line form an included angle of 30-60 degrees. In the valve pin spacer disclosed by the utility model, a plurality of discharging grooves are formed in the wall of the groove, the discharging grooves are kept away from the positions of the cup head screw holes and narrower in depth, so that the strength of the spacer is enhanced and the problem that the spacer is easy to break in the prior art is effectively solved.
Description
Technical field
The utility model relates to the needle cushion block that a kind of needle nozzle is used, and belongs to TOP-TIP field.
Background technology
The needle cushion block that the needle nozzle of prior art is used, as shown in Figure 1, 2, 3, needle cushion block 1 is connected by hexagonal socket head cap screw hole 3 with flow distribution plate 2, described needle cushion block 1 comprises cushion block body 4, described cushion block body 4 is cylindrical, the top of described cushion block body 4 is provided with circular groove 5, bottom land 7 centers of described circular groove 5 are provided with the needle hole 6 of passing for needle, on the cell wall 8 of described circular groove 5, be evenly provided with vertically four discharge grooves 9, the micro plastics that needle is taken out of in motion process can be discharged through discharge groove 9; But because the line of centres of wherein two discharge grooves 9 on needle cushion block of the prior art and the line of centres in two hexagonal socket head cap screw holes 3 are located along the same line, and the degree of depth of discharge groove is darker, cause cushion block insufficient strength, after pressurized, easily in the middle of above-mentioned discharge groove 9, rupture, service life is short, and changing needle cushion block affects job schedule.
Utility model content
The utility model object is the needle cushion block that a kind of not easy fracture is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of needle cushion block, comprise cushion block body, and described cushion block body is cylindrical, the top of described cushion block body is provided with circular groove; The bottom land center of described circular groove is provided with the needle hole of passing for needle, is provided with two hexagonal socket head cap screw holes to the bilateral symmetry in described needle hole, and the line of centres in described two hexagonal socket head cap screw holes is the first RADIAL; On the cell wall of described circular groove, edge is circumferentially with a plurality of discharge grooves; The center line of described each discharge groove all passes through the center of circle of circular groove; The line of centres in described each discharge groove and needle hole is the second RADIAL, and described the second RADIAL and the first RADIAL form the angle of 30-60 degree.
Preferably, described discharge groove has four, along the circumferentially evenly setting of cell wall of circular groove.
Preferably, residing the second RADIAL of described each discharge groove and the first RADIAL are 45 degree.
Preferably, the degree of depth of described discharge groove is 1/4th of the cell wall degree of depth.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The needle cushion block of the utility model scheme, comprises cushion block body, and described cushion block body is cylindrical, and the top of described cushion block body is provided with circular groove; On the cell wall of described circular groove, edge is circumferentially with a plurality of discharge grooves, new construction is compared with original structure, and hexagonal socket head cap screw hole is avoided in the residing position of described discharge groove, and the discharge groove degree of depth changes shallow, make cushion block strength-enhanced, effectively solve the easily problem of fracture of cushion block pressurized.
