Abstract
The utility model relates to a screw connecting mechanism of an injection molding machine, and comprises a screw and a pre-molded shaft coupling. The terminal of the screw is provided with a rectangular spline which passes through the pre-molded shaft coupling gland and is limited by a semi ring; the pre-molded shaft coupling gland is fixed on the pre-molded shaft coupling; the tail part of the screw and the pre-molded shaft coupling are also provided with a bearing block. The screw connecting mechanism has the advantages of high bearing capacity, excellent neutralizing and guide characteristics, shallow tooth roots and low stress concentration, and greatly improves the connecting tightness and the operating stability of the screw; simultaneously, the rectangle spline can be conveniently processed, and can achieve high accuracy in the grinding method. The shaft coupling and the screw are connected in a separate way, which facilitates the maintenance of the whole structure, saves the cost and facilitates the replacement. The structure of the screw connecting mechanism is suitable for the fully electrical injection molding machine which has higher requirements than the ordinary injection molding machine.
Description
Technical field
The utility model relates to a kind of screw-rod connection of full electric injection molding machine, the screw-rod connection of clasp type spline in particularly adopting.
Background technique
The screw rod of existing common hydraulic injection molding machine connects the general singly-bound Placement that adopts, exist be subjected to force unbalance, can't self-aligning, damage screw rod connection part, the bad problem of screw rod rotation concentricity easily, and be generally directly between rotation shaft coupling and the screw rod and be connected, when in case pressure stress occurring with shaft coupling conquassation problem, screw rod replacing difficulty can occur and maybe need to change whole pre-molding apparatus, cause great waste.Particularly full electric injection molding machine is because the ejaculation and the preformed characteristic of its high speed and precision, operation stability to screw rod is higher than the requirement of common injection machine, especially small-sized all-electric injector, corresponding screw diameter is smaller, and therefore the centering to screw rod requires also just higher.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of screw rod bindiny mechanism that realizes the injection machine simple, that precision is high, the life-span is long, easy to maintenance is provided for the above-mentioned defective that overcomes prior art.
The utility model solves the problems of the technologies described above the technological scheme that is adopted:
The screw rod bindiny mechanism of injection machine comprises screw rod and preformed shaft coupling, it is characterized in that: the terminal one-tenth of described screw rod rectangular spline, and it passes preformed shaft coupling gland and spacing by semi-ring, and preformed shaft coupling gland is fixed on the preformed shaft coupling.
Above-mentioned screw rod tail and preformed shaft coupling also are provided with cushion block.
Compared with prior art, advantage of the present utility model is:
The screw rod connecting mode changes rectangular spline into by singly-bound, have the bearing capacity height, to neutral, guidance quality is good, tooth root is more shallow, stress is concentrated less advantage, has improved the connection tightness and the operation stability of screw rod greatly; Rectangular spline is easy to process simultaneously, can obtain higher precision with method for grinding.
Adopt gland to be connected between shaft coupling and the screw rod, and between the two pad is set, promptly split type connection so both had been convenient to safeguard total, also helped saving cost, being convenient for changing.When damaging shaft coupling, original structure need be changed the screw rod bindiny mechanism of whole pre-molding apparatus when stress is excessive, and the utility model only need be changed cushion block and get final product.
By above-mentioned improvement, it can be applicable in the full electric injection molding machine than common injection machine requirements at the higher level.
Description of drawings
Fig. 1 is the utility model embodiment's a graphics.
Fig. 2 is the utility model embodiment's a sectional view.
Fig. 3 is the partial enlarged drawing of A among Fig. 2.
Fig. 4 is a screw rod tail spline schematic representation.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2, shown in Figure 3, the screw rod bindiny mechanism of injection machine comprises screw rod 5 and preformed shaft coupling 1, and preformed shaft coupling 1 and preformed shaft coupling gland 4 are connected by screw, and screw rod 5 is spacing by semi-ring 3.
The spline of above-mentioned screw rod tail is a rectangular spline, sees Fig. 4.
Above-mentioned screw rod 5 afterbodys are installed cushion block 2, can directly bear screw rod 5 base pressures.Simultaneously, install when cushion block 2 damages and directly to change.
As depicted in figs. 1 and 2, screw rod 5 and preformed shaft coupling 1 link to each other with separately parts, and during use, motor rotates, and drives preformed shaft coupling 1 and rotates, and preformed shaft coupling 1 drives screw rod 5 rotations, does work such as preformed or injection.
Claims (2)
