Description

PU type mould pre-embedding device

Technical Field

The utility model relates to a stamping die technical field especially relates to a PU type mould is pre-buried device.

Background

The existing PU (polyurethane) products (including PU foaming, PPHC foaming and the like) are widely applied to parts such as automobile spare tire cover plates, storage plates, bearing plates and the like by virtue of the characteristics of light weight, high strength and the like. When in compression molding, the PU product needs to embed the embedded part in the mold into the product, so that the embedded part needs to be stored in the mold firstly.

At present, the existing PU molds comprise PU foaming molds, PPHC foaming molds and the like. When the product is provided with the pre-buried plastic part, the leakage between the plastic part and the mold core can occur, thereby influencing the overall appearance quality of the product.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the shortcoming that exists among the prior art, and the pre-buried device of a PU class mould that proposes, through embedding rubber spare between built-in fitting and mould benevolence, can avoid the condition that appears leaking the material between working of plastics and the mould benevolence, effectively improved the whole appearance quality of product.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a pre-buried device of PU class mould, includes mould benevolence, the embedded part of pre-buried embedding on mould benevolence, be equipped with a rubber spare between inserts and the mould benevolence, the inboard of rubber spare is contradicted with the inserts and is connected, direction of height is clearance connection between rubber spare upper end outside portion and the mould benevolence.

Preferably, the clearance between the outer side part of the upper end of the rubber part and the mold core in the height direction is 0.5-1 mm.

Preferably, the outer side part of the lower end of the rubber part is in interference connection with the mold core.

Preferably, the interference magnitude between the outer side part of the lower end of the rubber part and the die core is 0.1-0.15 mm.

Preferably, the insert is a plastic piece.

The utility model discloses following beneficial effect has: the utility model relates to a PU mould pre-embedding device, which comprises a mould core and an embedded piece embedded on the mould core, wherein a rubber piece is arranged between the embedded piece and the mould core, the inner side of the rubber piece is in contact connection with the embedded piece, and the height direction between the outer side part of the upper end of the rubber piece and the mould core is in clearance connection; the utility model utilizes the elasticity and the viscosity of the rubber piece to clamp the insert in the rubber piece firstly and then to be embedded in the mould integrally, the elasticity of the rubber piece can completely fill the gap between the insert and the mould core, thereby avoiding the leakage; meanwhile, the stickiness of the rubber part can well embed the insert in the die, and various embedded position requirements are met.

Drawings

Fig. 1 is a schematic view of the overall structure of the present invention;

fig. 2 is an enlarged view of a portion a of fig. 1.

In the figure: 1 mould core, 2 inserts, 3 rubber parts, 3-1 upper end outer side part and 3-2 lower end outer side part.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a PU class mould pre-buried device, including mould benevolence 1, pre-buried inserts 2 of embedding on mould benevolence 1, be equipped with a rubber spare 3 between inserts 2 and the mould benevolence 1, the inboard of rubber spare 3 is contradicted with inserts 2 and is connected, the direction of height is clearance connection between 3-1 of the upper end outside of rubber spare 3 and the mould benevolence 1.

Wherein, the insert 2 is a plastic piece. In practical application, the insert 2 can be made of other materials according to the requirements of customers, so that the practical use requirements are met.

Wherein, the clearance amount between the outer side part 3-1 of the upper end of the rubber part 3 and the die core 1 in the height direction is 0.5-1 mm.

Specifically, the outer side part 3-2 at the lower end of the rubber part 3 is in interference connection with the mold core 1.

Specifically, the interference magnitude between the outer side part 3-2 of the lower end of the rubber part 3 and the die core 1 is 0.1-0.15 mm.

In this embodiment, the left and right sides of the outer side portion 3-2 of the lower end of the rubber member 3 are in interference connection with the mold core 1, and the interference magnitude is further preferably 0.1mm, so that the gap between the plastic member and the mold core can be completely filled by using the elasticity of the rubber member, and the material leakage is avoided.

In the embodiment, the insert is firstly clamped in the rubber piece by utilizing the elasticity and the viscosity of the rubber piece and then integrally embedded in the mold, and the elasticity of the rubber piece can completely fill the gap between the insert and the mold core, so that the condition of material leakage is avoided; meanwhile, the stickiness of the rubber part can well embed the insert in the die, and various embedded position requirements are met.

In addition, it should be noted that the mold core, the rubber member, the insert, and the like in the present embodiment are not substantially different from the prior art, and therefore, the structure, the shape, the operation principle, and the like thereof are not further described in detail herein.

In summary, the PU type mold pre-embedding device firstly clamps the insert in the rubber piece by utilizing the elasticity and the viscosity of the rubber piece, and then integrally pre-embeds the insert in the mold, and the elasticity of the rubber piece can completely fill the gap between the insert and the mold core, so that the condition of material leakage is avoided; meanwhile, the stickiness of the rubber part can well embed the insert in the die, and various embedded position requirements are met.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
