Description

Die bottom plate

Technical Field

The utility model relates to a mould technical field, in particular to mould bottom plate.

Background

The mould is various moulds and tools for obtaining required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production. In short, a mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts. The processing of the appearance of an article is realized mainly through the change of the physical state of a formed material. The element has the name of "industrial mother".

The existing die base plate needs to be provided with a plurality of threaded holes in the middle of the base plate, so that the base plate is connected with other parts on the base plate, the threaded holes are formed by tapping a tapping machine, the existing die base plate is often prepared from marble materials, if the tapping machine is used for tapping, the base plate is easy to crack, or small cracks are generated, and the strength of the die base plate is low.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a mould bottom plate to solve the problem that current mould bottom plate intensity is low.

The utility model provides a die bottom plate, the package rubbing board body with locate the many spliced poles at plate body middle part, plate body and each the position that the spliced pole corresponds all is equipped with a smooth blind hole, the spliced pole is located one in the smooth blind hole, each the middle part of spliced pole all is equipped with a connecting hole.

Above-mentioned mould bottom plate is through setting up smooth blind hole on the plate body for the plate body only needs the smooth hole of processing in the course of working, and is low to the destruction degree of plate body, can not produce the crack, has improved the intensity of plate body, and connecting hole on the rethread spliced pole is connected with other components and parts, realizes connection function.

Furthermore, an expansion gap is formed in the lower end of the connecting column, and an extrusion gasket is arranged on the inner side of the connecting column and in a position corresponding to the expansion gap.

Further, the height of the connecting column is smaller than the depth of the smooth blind hole.

Further, smooth blind hole with the spliced pole interference fit.

Further, the connecting column is a metal column.

Furthermore, the edge of the plate body is provided with a chamfer structure.

Further, the hole depth of the connecting hole is smaller than the thickness of the connecting column.

Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. Several embodiments of the invention are given in the accompanying drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" 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 as used herein are for illustrative purposes only.

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 invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 3, a mold bottom plate according to a first embodiment of the present invention includes a plate body 10 and a plurality of connecting posts 20 disposed in the middle of the plate body 10, wherein a smooth blind hole 11 is disposed at a position of the plate body 10 corresponding to each connecting post 20, the connecting posts 20 are disposed in the smooth blind holes 11, and a connecting hole 21 is disposed in the middle of each connecting post 20.

Above-mentioned mould bottom plate is through setting up smooth blind hole 11 on the plate body for plate body 10 only needs the smooth hole of processing in the course of working, and is low to the destruction degree of plate body 10, can not produce the crack, has improved the intensity of plate body 10, and connecting hole 21 on the rethread spliced pole 20 is connected with other components and parts, realizes connection function.

Referring to fig. 4, a mold bottom plate according to a second embodiment of the present invention is different from the first embodiment in that an expansion gap 22 is disposed at a lower end of the connecting column 20, and a pressing pad 23 is disposed at a position corresponding to the expansion gap 22 at an inner side of the connecting column 20, so that the connecting hole 21 is connected to a connecting member and then presses the pressing pad 23 to expand the expansion gap 22, so that the connecting column 20 is more tightly connected to the plate 10

Specifically, in the present embodiment, the height of the connecting column 20 is smaller than the depth of the smooth blind hole 11, so that the connecting column 20 is completely accommodated in the smooth blind hole 11.

Specifically, in the present embodiment, the smooth blind hole 11 is in interference fit with the connecting column 20, so that the connecting column 20 is tightly connected with the board body 10.

Specifically, in the present embodiment, the connecting column 20 is a metal column to improve the strength of the connecting column 20, and specifically, the connecting column 20 may be made of a material with better economical efficiency, such as an iron column.

Specifically, in the present embodiment, the edge of the plate body 10 is provided with a chamfer structure, so that the edge of the plate body 10 is smooth.

Specifically, in this embodiment, the depth of the connecting hole 21 is smaller than the thickness of the connecting post 20, so as to prevent other components connected to the bottom plate of the mold from contacting the plate 10, and further prevent the plate 10 from being damaged.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention.
