Embodiment 1

[0042] Such as figure 2 As shown, the shaft connector 1 of the present invention includes two adjacent sets of shaft sleeves. The shaft sleeve set on the left side includes a first sleeve 11 and a second sleeve 12 for a shaft to be sleeved (not shown in the figure) to pass through. The first sleeve 11 is formed with a first groove 111 opening upward. A second groove 121 opening downward is formed on the second sleeve 12 . The groove widths of the first groove 111 and the second groove 121 are adapted to the shaft to be sleeved. The first groove 111 and the second groove 121 radially fix the shaft to be sleeved from below and above respectively, so as to be sleeved on the shaft to be sleeved on.

[0043] Specifically, the groove bottoms of the first groove 111 and the second groove 121 are arc-shaped structures, and the arc shape of the first groove 111 and the arc shape of the second groove 121 belonging to the same group of bushings Cooperate with the outer contour of th...

Embodiment 2

[0051] Such as Figure 5-7 As shown, the difference between this embodiment and Embodiment 1 is that the second sleeves of the two sets of shaft sleeves of the shaft connector 1' in this embodiment are adjacently arranged, thereby forming a common second shaft Set of 12'.

[0052] When connecting the shaft to be sheathed as a coaxial connection, the second shaft sleeve 12' is formed with a Figure 5 The common second groove 121' is shown. All the other parts are exactly the same as in Example 1, so no more details here

Embodiment 3

[0054] The difference between this embodiment and Embodiment 2 is that if the shaft connector 1' is used to connect two shafts parallel to each other, two sections of grooves whose central axes are parallel to each other are formed on the second bushing 12'. are respectively coaxial with the adjacent first grooves. The remaining parts are exactly the same as those in Embodiment 2, and will not be repeated here.

[0055] The present invention also provides a casting mold for casting the shaft connector of the present invention. The casting mold includes an upper mold with an upper chamber, and a lower mold with a lower chamber. Protrusions for forming the first groove and the second groove are respectively formed in the upper chamber and the lower chamber and extend out of the chamber.

[0056] Below to Figure 5 Take the shaft connector in the example as an example, refer to Figure 8-14 The mold used to cast the shaft connection is further described.

[0057] Such as F...

Abstract

The invention discloses a casting mold and a shaft connecting piece. The shaft connecting piece comprises two pairs of adjacent shaft sleeve groups, each shaft sleeve group comprises a first sleeve and a second sleeve which is located at one end of the first sleeve and is coaxial with the first sleeve, and the first sleeve and the second sleeve clamp a shaft piece respectively from two opposite sides of the circumference of the shaft piece to be sleeved. The casting mold comprises an upper mold with a first protruding portion and a lower mold with a second protruding portion. The shaft connecting piece is connected with two shafts through two pairs of shaft sleeve groups, the shaft piece is connected through a first groove and a second groove which are opposite in opening directions, are matched with each other and are arranged on the first sleeve and the second sleeve, and the shaft connecting piece is convenient to use, saves raw materials and reduces production cost. The casting mold performs casing of the shaft connecting piece through the upper mold and the lower mold which are matched with each other, a cast hole piece in the prior art is omitted, blockage caused by the fact that the quitting direction of the cast hole piece is reversely perpendicular to rapping direction of the upper mold and the lower mold is avoided, and the rate of finished products is improved.

Description

technical field [0001] The invention relates to a connecting piece and its casting mold, in particular to a casting mold for connecting shaft pieces and a shaft connecting piece. Background technique [0002] A shaft connector is a component used to connect shafts, such as figure 1 As shown, it includes a main body 1", and a connecting hole 2" is provided inside the main body 1" through two opposite end faces of the main body. [0003] Another example figure 1 As shown, in the prior art, the casting mold used to cast the shaft connector of the above structure includes an upper mold 3 "with a groove and a lower mold 4" with a groove that is adapted to the upper mold 3 ", The upper mold 3" and the lower mold 4" cooperate to form a mold cavity for casting the body 1". The casting mold also includes a casting hole 5" for forming the connecting hole 2", commonly used as a slider or an oblique pin, and the part of the casting hole 5" with the same structure as the mold chamber ...
