Abstract

The utility model discloses a kind of quadric injection mould containment vessel; comprise the drain pan be made up of PC material; the sidewall of described drain pan is provided with the lug boss be made up of TPU material; also comprise the sidewall portion of being made up of TPU material be injection-moulded in base side walls, the welding area of described sidewall portion and drain pan wraps up the lug boss of described drain pan.Containment vessel of the present utility model; PC and TPU material can be adopted to be combined by secondary injection molding, can the higher PC material of first injection mo(u)lding temperature, then the TPU material that secondary injection molding temperature is lower; utilize the injection mo(u)lding temperature difference of bi-material, be welded together.Preferably, at both calmodulin binding domain CaMs, the lug boss that drain pan protrudes is wrapped by completely, adds both welding areas.

Description

A kind of quadric injection mould containment vessel

Technical field

The utility model belongs to protection and the operative installations of numerals sum consumable electronic product, more precisely, relates to a kind of containment vessel of electronic product.

Background technology

Containment vessel series products in the market, major part is the purposes as decoration, and adopt PC and TPU material by the containment vessel of secondary injection molding for part, PC with TPU bound fraction is easily separated and comes off, and have impact on the experience of user.

Utility model content

The utility model, in order to solve problems of the prior art, provides a kind of quadric injection mould containment vessel.

In order to realize above-mentioned object; the technical solution of the utility model is: a kind of quadric injection mould containment vessel; comprise the drain pan be made up of PC material; the sidewall of described drain pan is provided with the lug boss be made up of TPU material; also comprise the sidewall portion of being made up of TPU material be injection-moulded in base side walls, the welding area of described sidewall portion and drain pan wraps up the lug boss of described drain pan.

Preferably, described lug boss is provided with multiple, is evenly distributed on the sidewall of drain pan.

Containment vessel of the present utility model; PC and TPU material can be adopted to be combined by secondary injection molding, can the higher PC material of first injection mo(u)lding temperature, then the TPU material that secondary injection molding temperature is lower; utilize the injection mo(u)lding temperature difference of bi-material, be welded together.Preferably, at both calmodulin binding domain CaMs, the lug boss that drain pan protrudes is wrapped by completely, adds both welding areas.

Accompanying drawing explanation

Fig. 1 shows the structural representation of the utility model containment vessel.

Fig. 2 shows the partial schematic diagram of posetionof weld in Fig. 1.

Embodiment

The technical problem solved to make the utility model, the technical scheme of employing, the technique effect easy to understand obtained, below in conjunction with concrete accompanying drawing, be described further embodiment of the present utility model.

With reference to figure 1, Fig. 2; the utility model provides a kind of quadric injection mould containment vessel; comprise the drain pan 1 be made up of transparent PC material; its material itself has the high grade of transparency, higher intensity; be easy to injection mo(u)lding and the advantage such as painted; and be convenient to the multiple aftertreatment technologys such as spraying, plating, printing, stickup gadget, for the personalized design of mobile phone protecting case provides advantage.The shape at the mobile phone back side can be seen by transparent bonnet clearly, meet the psychological needs that user shows mobile phone brand.The sidewall of described drain pan 1 is provided with lug boss 11; also comprise the sidewall portion 2 of being made up of TPU material be injection-moulded on drain pan 1 sidewall; its material itself has the high grade of transparency, preferably elasticity, be easy to injection mo(u)lding and the advantage such as painted; be used as the containment vessel material of electronic product; not only there is good decorative effect, and grip good hand touch.In routine use, the edge of mobile phone is the most easily collided and is worn and torn, and particularly when mobile phone falls from eminence freely falling body, the TPU of containment vessel side can cushion the impulsive force dropped, and reduces the damage that external force causes mobile phone.Described sidewall portion 2 and the welding area of drain pan 1 wrap up the lug boss 11 of described drain pan 1.Preferably, described lug boss 11 is provided with multiple, is evenly distributed on the sidewall of drain pan 1.Form the toothed design of dove-tail between multiple lug boss 11, parts of tooth too increases both welding area.Preferably swallowtail trough structure further increases both bond strengths, makes it to be not easy separation when being subject to external force and tearing and comes off.

Containment vessel of the present utility model; PC and TPU material is adopted to be combined by secondary injection molding, can the higher PC material of first injection mo(u)lding temperature, then the TPU material that secondary injection molding temperature is lower; utilize the injection mo(u)lding temperature difference of bi-material, be welded together.Preferably, at both calmodulin binding domain CaMs, the lug boss that drain pan protrudes is wrapped by completely, adds both welding areas.

The utility model is by preferred embodiment having carried out detailed explanation.But, by studying carefully above, concerning the change of each execution mode with to increase be apparent for one of ordinary skill in the art.Being intended that these changes all and increasing of applicant has all dropped in scope that the utility model claim protects.

Claims
