Abstract
The utility model provides a mould structure of an integral gate, which adopts an integral forming technology, and avoids the defects that in the prior art, line clamping, excessive flash, segment difference and the like at the splicing position of a banana-shaped mould structure gate, the appearance and quality of a product can be improved. The mould structure of the integral gate has the advantages that the structure is simple, the cost is low, and the like, and has very strong market competitiveness.
Description
Technical field
The utility model relates to mould manufacturing field, particularly a kind of mould of monoblock type banana type cast gate.
Background technology
Cast gate claims charging aperture again, it is the narrow and small port between runner and the die cavity, also be the shortest and the smallest part, its effect is to make molten plastic produce acceleration when advancing die cavity, helps being full of rapidly die cavity, cast gate plastics elder generation condensation after the moulding, with near closed hollow ring, prevent that molten plastic from flowing backwards, it is too fast to avoid cavity pressure to descend, so that on goods, produce shrinkage cavity or depression, be convenient to make cast to coagulate material after the moulding and separate with goods.
Mould banana type cast gate is because of its curve form is gained the name like banana.In the mould of the many types of chamber finding of be mainly used in surface quality requirement height, producing in enormous quantities.In the process of ejecting, cast gate is separated with product automatically, need not carry out cast gate excision processing again.
The mould structure of banana type cast gate in the prior art, it generally adopts spliced structure: two mold inserts about doing--left mold insert and right mold insert.When injection moulding, left side mold insert and right mold insert are stitched together, form the mould structure of banana type cast gate such as Figure 110 0, plastic material injects die cavity through banana type cast gate during moulding, cooling forming, its effect is as shown in Figure 1: do like this and can produce the mold insert trace at the stitching position of product, promptly clamp 130, as shown in Figure 1.Simultaneously, occur bad defectives such as section difference and batch peak again easily at stitching position, thereby can have influence on the outward appearance of product.
Therefore, prior art has yet to be improved and developed.
The utility model content
The purpose of this utility model is to provide a kind of monoblock type valve gated mold structure.The sign an undertaking defectives such as clamp, batch peak and section difference of structure cast gate stitching position of banana pattern of the prior art have been avoided.
In order to achieve the above object, the utility model has been taked following technical scheme:
A kind of mould structure of monoblock type cast gate, wherein, it is crooked that the cast gate of mould is made part, is the banana type, and the described cast gate structure that is formed in one.
The mould structure of described monoblock type cast gate, wherein, described pouring gate structure connects runner, and its end section size that is connected with runner is bigger, and be connected an end section size with the product inner surface less
Compared to prior art, the mould structure of the monoblock type cast gate that the utility model provides, the defectives such as clamp, batch peak and section difference of banana type structure cast gate stitching position of the prior art have been avoided, thereby the outward appearance and the quality of product have been improved, simultaneously have simple in structure, low cost and other advantages again, have the very strong market competitiveness.
Description of drawings
Fig. 1 is the schematic diagram of banana type valve gated mold structure of the prior art.
The schematic diagram of the monoblock type banana type valve gated mold structure that Fig. 2 provides for the utility model embodiment.
Fig. 3 is the cutaway view of Fig. 2 along the A-A line.
The specific embodiment
The utility model provides a kind of mould structure of monoblock type cast gate, and is clearer, clear and definite for making the purpose of this utility model, technical scheme and effect, below with reference to accompanying drawing and give an actual example the utility model is further described.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also Fig. 2 and Fig. 3, it is the schematic diagram of monoblock type banana type pouring gate structure and its A-A line cutaway view of the monoblock type banana type valve gated mold made of the utility model embodiment, as shown in the figure, described monoblock type banana type pouring gate structure 200 forms by one-body molded technology, do not need splicing by mold insert, like this, gate location at described product just clamp can not occur, improved the presentation quality of product, avoid simultaneously occurring defectives such as batch peak and section difference again, made the quality of product increase again.
Described monoblock type banana type valve gated mold structure 200 also has the characteristics of general banana type cast gate, and its pouring gate structure bending is the banana type, can realize that molten plastic produces acceleration when advancing die cavity, is convenient to make cast to coagulate the effect that material separates with goods after the moulding.
Further, described monoblock type banana type valve gated mold structure 200 connects runner, and its end section size that is connected with runner is bigger, and be connected an end section size with the product inner surface less, and this structure is more conducive to the injection moulding melt and enters the product die cavity.
The purpose of this utility model is to provide a kind of mould structure of monoblock type cast gate, it can produce monoblock type banana type cast gate interface, the described banana type pouring gate structure structure that is formed in one, the defectives such as clamp, batch peak and section difference of banana type structure cast gate of the prior art stitching position when splicing have been avoided, thereby the outward appearance and the quality of product have been improved, simultaneously have simple in structure, low cost and other advantages again, have the very strong market competitiveness.
Be understandable that; for those of ordinary skills; can be equal to replacement or change according to the technical solution of the utility model and utility model design thereof, and all these changes or replacement all should belong to the protection domain of the appended claim of the utility model.
Claims (2)
1. the mould structure of a monoblock type cast gate is characterized in that, it is crooked that the cast gate of mould is made part, is the banana type, and the described cast gate structure that is formed in one.
2. the mould structure of monoblock type cast gate according to claim 1 is characterized in that, described pouring gate structure connects runner, and its end section size that is connected with runner is bigger, and be connected an end section size with the product inner surface less.
