In the present invention, the mold cavity is formed between the inner wall of the mold cavity and the outer wall of the mold cavity by the cooperation of the upper mold cavity, the lower mold cavity and the mold core. This arrangement makes the parting outside the mold cavity when the mold is closed, and the sealing lip of the product There is no type classification, which avoids the occurrence of burrs on the lip of the product, and effectively improves the quality and production pass rate of rubber products.

Description

A kind of oil filler sheath mold

technical field

The invention relates to the technical field of moulds, in particular to an oil filler sheath mould.

Background technique

Due to the special position of the sealing lip of the oil filler boot, it is very easy to have drill flashes and burrs on the lip during processing. Cause product scrapping, serious waste of resources.

Contents of the invention

Based on the technical problems existing in the above-mentioned background technology, the present invention proposes a fuel filler jacket mold.

A fuel filler sheath mold proposed by the present invention includes: an upper template, a lower template and a mold core, wherein:

The upper template and the lower template are provided with insert grooves respectively, and an upper insert is installed in the insert groove of the upper template, and a lower insert is installed in the insert groove of the lower template, and the upper insert has an upper mold cavity , the lower insert has a lower mold cavity;

In the mold closing state, the mold core is located between the upper mold cavity and the lower mold cavity, and the upper mold cavity, the lower mold cavity and the mold core cooperate to form a mold cavity between the inner wall of the two and the outer wall of the mold core.

Preferably, a flow channel plate is also included, and in the mold closing state, the flow channel plate is located above the upper formwork and fixed with the upper formwork.

Preferably, it also includes a lifting frame, which is provided with a through hole through up and down. In the mold closing state, the lifting frame is located between the upper template and the lower template, and the upper insert and the lower insert are located inside the through hole .

In the present invention, by setting the upper insert on the upper template, setting the lower insert on the lower template, and setting the upper mold cavity on the upper insert, and setting the lower mold cavity on the lower insert, to utilize the upper mold cavity, lower mold The cavity and the mold core cooperate to form a mold cavity between the inner wall and the outer wall of the cavity. This arrangement makes the parting outside the cavity when the mold is closed, and there is no parting at the sealing lip of the product, thus avoiding It prevents the occurrence of burrs on the lip of the product, and effectively improves the quality and production pass rate of rubber products.

Detailed ways

Below, the technical solution of the present invention will be described in detail through specific examples.

As shown in Figures 1-6, Figure 1 is a structural schematic diagram of the upper insert in a fuel filler sheath mold proposed by the present invention; Figure 2 is a side view of Figure 1; Figure 3 is a A schematic diagram of the assembly of the upper insert and the upper template in the fuel filler sheath mold; FIG. 4 is a side view of FIG. 3; FIG. 5 is a structural schematic diagram of a fuel filler sheath mold proposed by the present invention in a mold closing state; FIG. 6 is a top view of FIG. 5 .

Referring to Figures 1-6, a fuel filler sheath mold proposed by the present invention includes: an upper template 1, a lower template 2 and a mold core, wherein: the upper template 1 and the lower template 2 are respectively provided with insert grooves, and An upper insert 3 is installed in the insert groove of the upper template 1, and a lower insert is installed in the insert groove of the lower template 2. The upper insert 3 has an upper mold cavity, and the lower insert has a lower mold cavity. In the mold closing state, the mold core is located between the upper mold cavity and the lower mold cavity, and the upper mold cavity, the lower mold cavity and the mold core cooperate to form a mold cavity between the inner wall of the two and the outer wall of the mold core.

As can be seen from the above, the present invention sets the upper insert 3 on the upper template 1, the lower insert on the lower template 2, and the upper mold cavity on the upper insert 3, and the lower mold cavity on the lower insert, so as to utilize The upper mold cavity, the lower mold cavity and the mold core cooperate to form a mold cavity between the inner wall and the outer wall of the mold cavity. This arrangement makes the parting outside the cavity when the mold is closed, and there is no parting at the sealing lip of the product. , so as to avoid the occurrence of burrs on the lip of the product, so that the quality and production pass rate of rubber products can be effectively improved.

In addition, the present invention also includes a runner plate 4 and a lifting frame 5, the lifting frame 5 is provided with a through hole through up and down, and in the mold closing state, the runner plate 4 is located above the upper template 1 and is connected to the upper template. 1 is fixed; the lifting frame 5 is located between the upper template 1 and the lower template 2, and the upper insert 3 and the lower insert are located inside the through hole.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto, any person familiar with the technical field within the technical scope disclosed in the present invention, according to the technical solution of the present invention Any equivalent replacement or change of the inventive concepts thereof shall fall within the protection scope of the present invention.
