The utility model adopts the following technical scheme: the utility model provides a storage container convenient to drawing of patterns, including the body and a plurality of set up in through-hole on the lateral wall of body. The body has a cavity for placing an article and an opening in communication with the cavity. All the inner wall of through-hole all includes interconnect's slope section and vertical section, the slope section is close to the opening sets up, just the wall orientation of slope section the open-ended direction slope, the wall perpendicular to of vertical section the lateral wall of body.
Optionally, the slope of the sloping section is in the range of 15-35 °.
Optionally, the slope of the inclined section is 20 °.
Optionally, the inclined section and the vertical section are smoothly transitioned through a circular arc section.
Optionally, all the through holes are arranged on the side wall of the body in a row.
Optionally, the inner side and/or the outer side of the side wall of the body is provided with a reinforcing rib.
Optionally, the body is a structure gradually expanding towards the opening.
The utility model has the advantages that: the utility model provides a container, including the body and set up in through-hole on the lateral wall of body sets up the slope section in the through-hole be close to open-ended position, and the slope wall of slope section makes mould and through-hole can not block, can reduce the resistance of mould when the drawing of patterns effectively. The inner wall of the through hole close to the opening is designed into an inclined structure, and other positions are vertical structures, so that only the freedom degree of movement towards the opening direction exists between the object container and the mold, and the injection molding is facilitated. In addition, a forced demoulding mode can be adopted during demoulding, the mould is simple in structure, and investment and maintenance cost can be effectively reduced.

Detailed Description
The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown.
Referring to fig. 1-4, the present invention provides a container for easy demoulding, which comprises a body 1 and a plurality of through holes 2 disposed on a sidewall 11 of the body 1.
The body 1 has a cavity for placing an article and an opening 12 communicating with the cavity. The inner walls of all the through holes 2 comprise an inclined section 21 and a vertical section 22 which are connected with each other, the inclined section 21 is arranged close to the opening 12, the wall surface of the inclined section 21 inclines towards the direction of the opening 12, and the wall surface of the vertical section 22 is perpendicular to the side wall 11 of the body 1.
The inclined section 21 is arranged at the position of the through hole 2 close to the opening 12, the inclined wall surface of the inclined section 21 prevents the mold and the through hole 2 from being clamped, and the resistance of the mold during demolding can be effectively reduced. And the directions of the inclined wall surfaces of the inclined sections 21 of all the through holes 2 face the opening 12, so that the smooth demoulding of the container is ensured. The inner wall of the through hole 2 close to the opening 12 is designed to be an inclined structure, and other positions are vertical structures, so that only the freedom degree of movement towards the opening 12 is provided between the object container and the mould, and the injection molding is facilitated. In addition, a forced demoulding mode can be adopted during demoulding, the mould is simple in structure, and investment and maintenance cost can be effectively reduced.
The through hole 2 may be a kidney-shaped, circular or square shape, which is not limited in the embodiment of the present invention. The inner wall of the through hole 2 is smooth and has no burrs. The containing container can be the structure of basket, box or barrel, and the size can be adjusted according to the actual production needs, the embodiment of the utility model provides a do not do specifically to this and restrict.
Optionally, the slope of the inclined section 21 is in the range of 15-35 °. When the inclination of the inclined section 21 is more than 35 degrees, the inclination is too large and is difficult to eject, and the demolding is difficult; when the inclination of the inclined section 21 is less than 15 degrees, the inclination is too small, and the inclined wall surface of the inclined section 21 is longer, so that the thickness of the inclined section 21 is thinner and is easy to damage; when the inclination of the inclined section 21 is in the range of 15 to 35 °, not only smooth demolding can be ensured, but also the structural strength of the inclined section 21 can be made. Specifically, the inclination of the inclined section 21 is 20 °.
Optionally, the inclined section 21 and the vertical section 22 are smoothly transited by the circular arc section 23 to ensure that the product is not pulled when demoulding.
Alternatively, all the through holes 2 are arranged in a row on the side wall 11 of the body 1. The through holes 2 on the side wall 11 of the body 1 are regularly arranged in the mold stripping direction, so that the force application during forced ejection and mold stripping is facilitated.
Optionally, the inner side and/or the outer side of the side wall 11 of the body 1 are/is provided with the reinforcing ribs 13, so that the overall structural strength of the storage container can be increased, the service life of the storage container can be ensured on one hand, and the storage container is not easy to damage during demolding on the other hand.
Optionally, the body 1 is a structure gradually expanding towards the opening 12, so as to facilitate the demoulding separation between the product and the mould.
The above is only the preferred embodiment of the present invention, and not the patent protection scope of the present invention is limited thereby, and all the equivalent structure changes made by the contents of the specification and the drawings are directly or indirectly applied to other related technical fields, and all the same principles are included in the protection scope of the present invention.
