Abstract
The utility model discloses a thin inclined top mould which comprises a back mould and a bottom mould, wherein the back mould comprises a first layer of back mould and a second layer of back mould which are matched with each other; the second layer of back mould covers the first layer of back mould; a first angle ejector rod is arranged in the first layer of back mould; a second angle ejector rod is arranged in the second layer of back mould; the thickness of the second angle ejector rod is greater than that of the first angle ejector rod; the first angle ejector rod inside the first layer of back mould is 3.8 mm in thickness; the second angle ejector rod inside the second layer of back mould is 11 mm in thickness. The thin inclined top mould provided by the utility model has the following advantages and technical effects: the structure of the back mould is ingeniously divided into two layers; typing is carried out on the first layer according to the normal product inclined top manner; in the second layer, the angle ejector rod can be thickened at random, so as to enable the inclined top to be stronger, and a secondary ejection structure can be formed; full-automatic injection molding production can be achieved; the labor cost is greatly reduced, so that the economic benefits of enterprises are greatly increased.
Description
[technical field]
The utility model relates to a kind of mould, especially a kind of thin oblique top mould.
[background technology]
Mould is in industrial production, to make under external force blank become the instrument of the product that has given shape and size.Be widely used in stamping-out, die forging, cold-heading, extruding, metallic sintered products compacting, compression casting, and during the compression moulding of goods such as engineering plastics, rubber, pottery or the shaping of injection moulding process.Mould has specific profile or cavity shape, and the contour shape that application has cutting edge can make blank separate (stamping-out) by outline line shape.Application cavity shape can make blank obtain corresponding three-dimensional shape.Mould generally comprises dynamic model and two parts of cover half (or punch and die), the two partable.Separately time, take out product, while closing up, make blank inject mold cavity and be shaped.Mould is precision instrument, complex-shaped, bears the expansive force of blank, and structural strength, rigidity, case hardness, surface roughness and machining accuracy are all had higher requirements.
In existing mold, because of the limitation that product structure appearance and size requires, cause the release bulk of mould structure oblique top limited, the common way of oblique top is very thin, and processing is distortion very easily.Because of oblique top too thin, injection molded pressure load function influence, oblique top Production Life does not reach volume production requirement, and oblique top distortion fracture often occurs, often maintenance die, normally production shipment; The oblique top of reforming in addition, processing and manufacturing operation is many, complex process, and elapsed time is long, and maintenance cost is quite high.
[utility model content]
The purpose of this utility model is the deficiency existing for the above prior art, and a kind of precision and good rigidly are provided, and stops the risk of breakage that deforms, and greatly reduces the thin oblique top mould of the extra cost of mold repair input.
To achieve these goals, the utility model is achieved in that thin oblique top mould, comprises rear mold and bed die, and described rear mold is made up of the ground floor rear mold cooperatively interacting and second layer rear mold, and described second layer rear mold is covered in described ground floor rear mold top; Described ground floor rear mold arranges the first angle ejector rod, and described second layer rear mold arranges the second angle ejector rod, and the thickness of Thickness Ratio first angle ejector rod of described the second angle ejector rod is thick.
The thickness of the angle ejector rod in described ground floor rear mold is 3.8 millimeters, and the thickness of the angle ejector rod in second layer rear mold is 11 millimeters, and this structure self intensity in the situation that not affecting precision obtains maximum enhancing, better meets batch production.
In described ground floor rear mold, be provided with the back-off space that is used to form back-off hook position, injecting products is connected with described ground floor rear mold by the back-off position forming.
Compared with prior art, the advantage the utlity model has and useful technique effect are as follows: be divided into two-layerly by ingenious rear mode structure, ground floor is by normal product oblique top mode somatotype, and the second layer can arbitrarily be thickeied angle ejector rod, thereby allow oblique top become strongr, form secondary ejection structure; When operation, oblique top button bit is release for the first time; Then the action of push pedal for the second time, allows product depart from smoothly core; Can carry out full-automatic injection moulding and produce, greatly save labour turnover, Business Economic Benefit improves greatly.

[specific embodiment]
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail to explanation.
A kind of thin oblique top mould, as Figure 1-4, comprises rear mold 1 and bed die 2, and described rear mold 1 is made up of the ground floor rear mold 11 cooperatively interacting and second layer rear mold 12, and described second layer rear mold 12 is covered in described ground floor rear mold 11 tops.Wherein, described ground floor rear mold 11 arranges the first angle ejector rod 13, described second layer rear mold 12 arranges the second angle ejector rod 14, wherein, the thickness of Thickness Ratio first angle ejector rod 13 of described the second angle ejector rod 14 is thick, by addition two-layer transformation of rear mold 1, the second angle ejector rod 14 of second layer rear mold 12 is strengthened and become fully strong, original oblique top is thin, undercapacity is readily solved immediately, makes the thin yielding breakage problem of same product oblique top obtain cutting end solution.
Wherein, the thickness of the first angle ejector rod 13 in described ground floor rear mold 11 is 3.8 millimeters, the thickness of the second angle ejector rod 14 in second layer rear mold 12 is 11 millimeters, and this structure self intensity in the situation that not affecting precision obtains maximum enhancing, better meets batch production.In described ground floor rear mold 11, be provided with the back-off space that is used to form back-off hook position, injecting products is connected with described ground floor rear mold 11 by the back-off position forming.The narrow space in described back-off space, conventionally release to reach demoulding object by the mode of oblique top, oblique top requires mechanical processing process and motion process to deform, and guarantees self intensity.In described bed die 2, be provided for fixing Connection Block 22, so that fixing.
The utility model, by hierarchical design, just can make the size of angle ejector rod become sturdy, makes processing technology thereof more easy to control, and the precision of oblique top and rigidity can reach normal production requirement; It is strong that oblique top becomes, rigidity improve, move smooth and easy, the risk of breakage that can not deform again, greatly reduce mold repair drop into extra cost; Completely practicable full-automatic injection moulding is produced, the improved technological highlights of mould structure of greatly enhancing productivity; The goods little to product design size, batch is large, precision is high, the most applicable practicality of this ramp-roof structure.
More than describe preferred embodiment of the present utility model in detail, should be appreciated that the ordinary skill of this area just can be made many modifications and variations according to design of the present utility model without creative work.Therefore, all technical staff in the art according to the utility model design on prior art basis by logic analysis, reasoning or according to the available technical scheme of limited experiment, all should be among by the determined protection domain of these claims.
