Description

Packing carton mould base

Technical Field

The utility model relates to the technical field of molds, in particular to a packaging box mold base.

Background

In the packaging field, plastic packaging boxes are often used for external packaging, the plastic packaging boxes are generally formed by using injection molds, in the actual production process, packaging boxes with different specifications are often required to be manufactured according to the appearance of packaged products, the unit packaging weight and other factors, and accordingly, the packaging molds with different specifications are required. The existing air exhausting mode of the stamping part die is realized by opening and closing the upper die and the lower die for a plurality of times before pressurizing, and the air exhausting mode is used for parts with fewer holes and more regular surfaces. However, for the porous structure of the packaging box, the upper and lower dies are opened and closed to exhaust, so that the gas in the dies cannot be completely exhausted, and the problem of air holes on the manufactured product cannot be solved, and the use requirement cannot be met.

Disclosure of Invention

Based on this, it is necessary to provide a package mold base in view of the above-mentioned problems.

The utility model provides a packing carton mould base, includes the lower mould, be provided with the lower die cavity in the lower mould, lower die cavity middle part is provided with the boss, be provided with annular wire casing on the boss, be provided with a plurality of thimble holes in the wire casing, boss limit portion is provided with a plurality of exhaust grooves, be provided with logical groove on the lower die cavity inner wall, the exhaust groove passes through logical groove and external intercommunication.

Preferably, the depth of the exhaust groove is 0.035-0.04 cm.

Preferably, a converging groove is formed in one side, away from the boss, of the exhaust groove, and the converging groove is used for communicating a plurality of exhaust grooves with the through grooves.

Preferably, the side part of the lower die is provided with a positioning hole.

The utility model has the advantages that: utilize the thimble hole to make wire casing and external intercommunication, exhaust groove and logical groove of cooperation boss limit portion, the gas that the inside accumulation of discharge mould that can be very big is held up, and the product that makes is more closely knit, and the surface is smooth, no gas pocket, improves the use experience of product, satisfies customer's user demand.

Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The present utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the utility model, whereby the utility model is not limited to the specific embodiments disclosed below.

It will be understood that when an element is referred to as being "fixed" or "disposed" on another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only and are not meant to be the only embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-2, a packaging box die base comprises a lower die 1, a lower die cavity is arranged in the lower die 1, a boss 11 is arranged in the middle of the lower die cavity, an annular wire groove 12 is arranged on the boss 11, a plurality of jacking holes 13 are arranged in the wire groove 12, a plurality of exhaust grooves 14 are arranged at the edge of the boss 11, a through groove 15 is arranged on the inner wall of the lower die cavity, and the exhaust grooves 14 are communicated with the outside through the through groove 15. Specifically, the lower die 1 is concaved inwards to form a lower die cavity, a boss 11 is arranged at the bottom of the lower die, an annular wire slot 12 is arranged on the boss 11, a thimble hole 13 is arranged in the wire slot 12, a thimble (not shown in the figure) is conveniently inserted, a workpiece after injection molding is ejected through the thimble hole 13, and the number of the thimble holes 13 can be set according to the shape and the size of the workpiece to be injection molded, so that the injection molding method is not limited specifically. Simultaneously wire casing 12 intercommunication a plurality of header pin hole 13 for the clearance between gas accessible wire casing 12 and the header pin hole 13 between boss 11 and the work piece is discharged, makes the product of making more closely knit, and the surface is smooth, there is not the gas pocket, and set up a plurality of exhaust grooves 14 at boss 11 ring side, exhaust grooves 14 communicate with the external world through the logical groove 15 on the die cavity inner wall down, can play the design purpose of cooperation exhaust, and need not to open the mould again, only need on current mould the improvement design can, very big reduction the mould cost. In the present application, the depth of the exhaust groove 14 is 0.035 to 0.04cm.

As shown in fig. 1-2, a converging groove 16 is disposed on a side of the exhaust groove 14 facing away from the boss 11, and the converging groove 16 is used for communicating a plurality of exhaust grooves 14 with the through groove 15. Specifically, a plurality of vent grooves 14 can be communicated by using one converging groove 16, and the discharged gas is sent out, so that a plurality of vent grooves 15 are not required to be arranged on the inner wall of the lower die cavity in a one-to-one correspondence manner, and the structural strength of the lower die 1 does not reach the standard.

As shown in fig. 1-2, the side of the lower die 1 is provided with a positioning hole 17 for matching with a guide post (not shown in the figure), so that the die is not misplaced during die assembly.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
