Description of the invention: [Technical field to which the invention pertains] % The present invention provides a roller synchronous linker for a linear slide rail, in which, in particular, the button can be held in a minimum contact area In the technical field between the spacers, the crucible can reduce the frictional resistance of the rollers and has a good retention effect. The present invention further provides a roller synchronous coupling manufacturing of a linear slide. The term "mold" is particularly a technical field in which the roller synchronous connector of the present invention can be quickly manufactured by a male mold, a female mold and a split mold slider. [Prior Art] Figures 1 to 3 are conventional techniques shown in US6626572, in which the connector (10) is composed of a plurality of mutually parallel spacers (1)), and two bridges are provided at the connecting ends of the respective bodies (11). 02) The surface between the two spacers (11) has a holding portion (lla) whose radius of curvature coincides with the radius of curvature of the roller (2〇), so that the roller (20) is kept at two intervals. Between the bodies (11); please cooperate with Figure 4A~4D, the connector (1〇) is made of a mold (3〇) which is made up of the male mold (31) and the female The mold (32) is composed of a male and female mold (31) (32) having a plurality of parallel column nests (33) on the mating face recess, the column nest (33) providing a roller (2〇) first The male and female molds (31) (32) are additionally provided with a spacer cavity (34;) or a joint cavity (35) around the column nest (33), and the male mold (31) is opposite each other. Each of the positions of the column nests (33) is provided with a shooting port (36) so as to be smaller than the diameter of the roller (20) through the injection port (36) and the 1333033 spacing d1 and the lower opening spacing d2 after clamping. Keep the roller (20) in two or two intervals Between (41), the two holding portions (41a) further have an opening at the bottom end to push down the diverging parting portion (41b); and the two bridges are disposed at both ends of the plurality of spacers (41) The connecting portion (42) is disposed at a position opposite to the parting portion (41b). Please refer to Figure 10 and XI, which illustrate the implementation of the present invention. • In the state of a linear slide, the linear slide is made up of a slider (1) and a slider that sits on the slide rail (1). (2) Two sets of end caps (3) disposed at both ends of the slider (2), and forming at least two circulating passages therebetween, and the roller synchronous jointer (40) of the present invention is installed in the passage So that it can maintain the slip between the slider (2) and the slider (1) in a plurality of rollers (20), and thus has the expected function that can be implemented. Referring to FIG. 12, which is a second embodiment of the roller synchronous connector (40) of the present invention, the embodiment mainly illustrates that the holding portion (41a) of the spacer (41) is a cylindrical surface, and the surface is A plurality of grooves (41c) are provided for the function of storing grease, so that the roller can adhere to the grease, thereby effectively reducing the frictional resistance between the upper and lower edges of the roller and the holding portion (41a) to ensure the roller. Smoothness in operation; in addition, its parting part (41b) must be set with a curved surface. Please refer to the thirteenth embodiment, which is a roller synchronous connector (40) 1333033 of the present invention. The outer male mold (52) is provided with a plastic injection port (52d) at each of the spacer cavity (52c). And a recessed portion (52e) that can form another connecting portion (42) is recessed at the other bottom end of the spacer cavity (52c); the top surface of the splitter slider (53) is collocated The bottom surface of the male mold (52) and the horizontal reference surface of the female mold (51) are convexly provided with a plurality of sub-modules (53a), and a spacing groove (53b) is formed between the two sub-modules (53a). The sub-module (53) is inserted into the limiting groove (52b), so that the halving modules (53) are placed one by one between the bottom ends of the two-part spacer cavity (52c), and two or two The surface of the spacing groove (53b) in the sub-module (53) forms an upwardly diverging opening for molding the parting portion (4ib) and the connection (42) of the roller synchronous connector (4) of the present invention. The formed inner frame 'and the sub-module (53a) forms the surface of the spacer groove (53b) to form a parting portion (41b) in which the opening is gradually diverged. In actual production, the present invention first makes the male mold (52) facing the female mold (51), and then operates the split mold slider (53) to match the male and female molds (52) (51). After the mold is formed, the spacer (41) and the connecting portion (42) can be injection molded, and then the manufactured roller synchronous connector (40) can be easily taken out by the reverse splitting operation. From the above description, the present invention and its molds can achieve the following advantages: • The retaining portion (4ia) of the present invention stores grease therein, and the roller (20) operates more smoothly, and The wear situation of the holding portion 1333033 (41a) is effectively reduced. ^ 2 · The invention can be inserted into the roller (20) before injection molding - direct molding, which is more convenient and faster than the conventional operation, so that the development can be revolutionized and highly creative and economical. It makes the production efficiency of the injection machine more efficient for industrial use, so it is in line with economic benefits. 3. The holding portion (41a) of the present invention is only in contact with the roller (20) at the upper and lower end edges, which reduces the contact area with each other, effectively reduces the resistance of the roller (20), and provides a good roller (20). Retention, which in turn reduces the power required for linear slippery operation. In summary, the present invention is a highly invented technical concept, which should meet the requirements of a patent application, and apply in accordance with the law. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the average variation and the repairing of the scope of the patent application of the present invention should still be It is within the scope of the invention.
