Description
Technical field
This utility model is related to a kind of while gear forming mould with straight-tooth and helical teeth, belongs to Machining Technology
Field.
Background technology
Gear is generally divided into direct tooth type, plagiodont according to the profile of tooth on surface.But due to the market demand, it may appear that straight-tooth and tiltedly
Tooth occurs on identical product simultaneously, as shown in Figure 1.The product has helical teeth outline, and is embedded with straight-tooth, the straight-tooth
Arrange and helical teeth end top.Due to the particularity of the product, cause the demoulding cannot be completed using general slide block depanning, therefore need
The new stripping forming mould of exploitation.
Utility model content
The purpose of this utility model is to solve the above problems, and proposes the product mould that a kind of straight helical teeth coexists.
The purpose of this utility model is achieved through the following technical solutions：
The product mould that a kind of straight helical teeth coexists, include successively upper mounted plate, front template, rear pattern plate, backing plate,
Ejector retainner plate and bottom plate, it is characterised in that：Die cavity is provided with the rear pattern plate, on the outside of the die cavity helical teeth, a helical teeth is equipped with
Mold insert, the die cavity lower end straight-tooth end are equipped with straight-tooth mold insert, are provided with bearing outside the helical teeth mold insert, the helical teeth mold insert with
Straight-tooth mold insert cooperates.
Preferably, there is runner, the runner to be placed in the side at sprue gate in the front template.
Preferably, the helical teeth mold insert is placed in rear pattern plate with the straight-tooth mold insert.
Preferably, an ejector sleeve for being used for ejecting product is provided with the ejector retainner plate, and one end of the ejector sleeve is produced with molding
Product are abutted.
Preferably, front mould mold insert is provided with the front template.
Preferably, the helical teeth mold insert is sheathed on the straight-tooth mold insert upper end, and not with the die cavity straight-tooth end in contact.
The beneficial effects of the utility model are mainly reflected in：Solve while having straight-tooth difficult with the product depanning of helical teeth
Problem, while, it is ensured that the concentricity and its function of two kinds of profiles of tooth of product.
Description of the drawings
Below in conjunction with the accompanying drawings technical solutions of the utility model are described further：
Fig. 1：Shaped article structural representation of the present utility model.
Fig. 2：Cross-sectional view of the present utility model.
Specific embodiment
This utility model discloses the product mould that a kind of straight helical teeth coexists, and in conjunction with shown in Fig. 2, this mould is successively
Include upper mounted plate, front template 1, rear pattern plate 2, backing plate, ejector retainner plate and bottom plate.Die cavity 6 is provided with the rear pattern plate 2,
A helical teeth mold insert 7 is equipped with the outside of the die cavity helical teeth, the die cavity lower end straight-tooth end is equipped with straight-tooth mold insert 8, in order to de-
The more preferable rotation of mold insert during mould, is provided with bearing 9 outside the helical teeth mold insert 7.The helical teeth mold insert 7 and 8 phase interworking of straight-tooth mold insert
Close to guarantee the concentricity and high-precision demand of shaped article.Specifically, the helical teeth mold insert 7 and the straight-tooth mold insert 8
It is placed in rear pattern plate 2.The helical teeth mold insert 7 is sheathed on 8 upper end of straight-tooth mold insert, and does not terminate with the die cavity straight-tooth
Touch.Front mould mold insert is provided with the front template.There is in the front template 1 runner 4, the runner 4 to be placed in the one of sprue gate 3
Side.An ejector sleeve 5 for being used for ejecting product is provided with the ejector retainner plate, and one end of the ejector sleeve 5 is abutted with shaped article.
Molding of the present utility model and demoulding principle under described briefly below：
Castable is entered from sprue gate 3, and the die cavity 7 for entering into molding by runner 4 is poured into a mould.After formed product, front,
Rear mold is molded.As product die cavity is arranged in rear pattern plate 2, after die sinking, need to carry out the demoulding.And both had on product straight
Tooth has helical teeth again so that product itself cannot be rotated, and now, ejector retainner plate exerts a force to ejector sleeve 5, drives ejector sleeve 5 to product
Direction is moved, and ejector sleeve 5 exerts a force to product so that product is moved to front template direction, and product helical teeth part glue position is by masterpiece
For helical teeth mold insert 7 so that helical teeth mold insert 7 is rotated, i.e., while ejection, helical teeth mold insert 7 is rotated, and is finally reached suitable
The purpose of sharp depanning.
This utility model still has multiple specific embodiments, all employing equivalents or equivalent transformation and the institute that formed
Have technical scheme, all fall within this utility model claimed within the scope of.
