Abstract
The utility model discloses a plastic helical gear mould, which comprises a core, a conical core, a gear ring, mould inserts, a movable mould plate, a fixed plate, a shim plate and a push rod. The core is installed in the conical core; the gear ring is connected with the mould inserts by a pin shaft; the mould inserts are sheathed on the conical core and matched with the movable mould plate by a bearing; the fixed plate is installed below the movable mould plate and connected with the shim plate by the pin shaft, and the push rod passes through the shim plate and the conical core. The utility model has the advantages that high-helix plastic helical gears can be easily demoulded, the production efficiency is greatly improved, and the rejection rate and the production cost are reduced. When the utility model demoulds, firstly, the cover of the mould is pulled up to open the movable mould plate and the fixed plate, and then, the push rod moves up to make the helical gear drive the gear ring to release the mould.
Description
Technical field:
The utility model belongs to a kind of gear die.
Background technology:
Mold injection molding is mainly adopted in the production of plastic beveled wheel at present.It has high efficiency, characteristics cheaply.Compare with metal gear, also have advantages such as sound in light weight, dry is low, self lubricity is good.But there is the problem of demoulding difficulty in the special construction of (β=20 °) plastic beveled wheel because the king bolt angle in actual production, its production efficiency is reduced greatly, and the percent defective height causes production cost to raise, and is unfavorable for the large-scale production manufacturing.
Summary of the invention:
The purpose of this utility model is: but the plastic beveled wheel mold of a kind of high efficiency, low-cost production king bolt angle is provided, to address the above problem.
The utility model is to constitute like this: it is by core (1), tapered core (2), gear ring (3), mold insert (4), moving platen (5), (6), fixed head (7), backing plate (8), push rod (9) is formed, and core (1) is contained in the tapered core (2), gear ring (3) is connected with mold insert (4) with bearing pin, mold insert (4) is enclosed within on the tapered core (2), and cooperates with moving platen (5), (6) by bearing (10), (11), fixed head (7) be contained in moving platen (6) below, and be connected with backing plate (8) with bearing pin, push rod (9) passes backing plate (8) and tapered core (2).
The utility model compared with prior art has and can make the smooth demoulding of large helix angle plastic beveled wheel, thereby makes advantages such as production efficiency raising greatly, percent defective and production cost reduction.During the demoulding, first pull-up die cover plate makes between moving platen (6) and the fixed head (7) and opens, and core (1) is extracted out from helical gear (12), and push rod (9) moves up then, makes helical gear (12) promote gear ring and rotates mould.
Description of drawings:
Accompanying drawing 1 is a schematic diagram of the present utility model.
The specific embodiment:
Embodiment of the present utility model: core (1) is contained in the tapered core (2), gear ring (3) is fixedlyed connected with mold insert (4) by bearing pin, mold insert (4) is enclosed within on the tapered core (2), with it movingly, and cooperate with moving platen (5), (6) by bearing (10), (11), fixed head (7) be contained in moving platen (6) below, and be connected with backing plate (8) with bearing pin, push rod (9) passes backing plate (8) and tapered core (2), withstands under the helical gear (12).
Claims (1)
1, a kind of plastic beveled wheel mold, it is by core (1), tapered core (2), gear ring (3), mold insert (4), moving platen (5), (6), fixed head (7), backing plate (8), push rod (9) is formed, it is characterized in that: core (1) is contained in the tapered core (2), and gear ring (3) is connected with mold insert (4) with bearing pin, and mold insert (4) is enclosed within on the tapered core (2), and by bearing (10), (11) with moving platen (5), (6) cooperate, fixed head (7) be contained in moving platen (6) below, and be connected with backing plate (8) with bearing pin, a bar (9) passes backing plate (8) and tapered core (2).
