Description

Universal die set for fixed mould

Technical field

The utility model relates to the processing and forming mould applications, refers to a kind of universal die set especially.

Background technology

Existing be applicable to various contour machining equipment such as plastic injection machine, punch press ... disassembly and assembly location etc. employed mould, the mould bases 2 of fixed base frame shown in Fig. 4-6 at fixed mould before the processing, which is provided with many T type grooves 21, cooperate T type nut 22 and pressing plate 23, pass pressing plate 25 by bolt 24 and be spirally connected with fixed mould 3 with trapezoidal nut 22.These mould bases 2 utilize T type groove 21 and T shape nut 22 as the clamping of mould and in conjunction with and fixing or dismounting has many shortcomings and inconvenience in actual fabrication and in using, as:

1, the making of T type groove 21 must use molding cutter by the processing of mould bases 2 outermost end ecto-entads, and processing is difficult for.

2, whole T type groove 21 must be made inner each face the processing of degree of precision, can insert the do combination relatively for T shape nut 22, and Gu Jiagongchengbenju crouches height not down.

3, T type groove 21 internal faces have the plane 211 that two places contact with T type nut 22, and this plane 211 connects that dihedral becomes the right angle and is quite sharp-pointed interior re-entrant angle, so when being subjected to the powerful drawing of T type nut 22, form the most weak part of intensity herein, be out of shape or what is heard arranged when splitting.

4, for avoiding above-mentioned indent angular deformation or splitting, just must increase pressurized plane 211 thickness to the mould bases surface, this can significantly increase material thickness and cost.

5, T type nut 22 also must cooperate this T type groove 21 to do accurate processing and appropriate cooperation, so also can increase the cost in the making.

6, the horizontal protuberance of these T type nut 22 Lower Halves just contacts with the interior concave plane 211 of T type groove 21 and forms direct stressed place, so can not be too thin, must increase thickness to have sufficient intensity, so except that increasing again the cost, the inner space of T type groove 21 must be strengthened again relatively, also can increase the difficulty of processing.

7, four limits of the mould bases 2 of T type groove 21 thickenings will form many concane gaps, can influence the stress intensity of whole mould bases 2.

The inventor in view of this, adhere to the experience of the abundant design of mechanical major for many years and actual exploitation and composition, research, studied improvement at above-mentioned structure and the defective of commonly using mould bases, the T type groove structure that a kind of innovation is provided is in the hope of improving all defect of commonly using mould bases fully.

Summary of the invention

Main purpose of the present utility model is to provide a kind of universal die set for fixed mould, be to make on the position of T type groove in desire, by side subdrilling one deep hole, processing one elongated hole is through in this deep hole on the surface again, utilize a cylinder with horizontal screw directly to insert in the deep hole, can pass elongated hole and this horizontal screw T type bolt that formation is connected briquetting that is spirally connected for bolt and fix the mould that to fix, become a kind of handling ease and lower-cost mould bases T type groove.

Another purpose of the present utility model is to provide a kind of universal die set for fixed mould, change into the stress contact plane of vertical sharp-pointed re-entrant angle circular-arc, take place with the situation of avoiding producing modification and rhegma as the sharp-pointed interior re-entrant angle of commonly using mould bases, also can moderate reduction and the distance on mould bases surface, reduce gross thickness and cost.

A purpose more of the present utility model is to provide a kind of universal die set for fixed mould, be to insert for columned cylinder by circular deep hole, this cylindrical material is obtained and handling ease, with low cost, and contacting with T type notch inner face no longer is easy compressive deformation or the interior re-entrant angle that very easily produces rhegma, its diameter can appropriateness reduces reducing cost, and also can significantly relax with the quality of fit in T type groove depth hole, and the practical advantage of many additions of multiplying each other is arranged.

Another purpose of the present utility model is to provide a kind of universal die set for fixed mould, elongated hole by reprocessing mould bases surface after the deep hole machining, then this elongated hole can be positioned in the corner fully, can not make each limit of whole mould bases produce many concane gaps, so can appropriateness reduce the integral thickness and the weight of whole mould bases to guarantee the intensity of whole mould bases, relatively under, material cost, processing cost, even the power that uses all can effectively reduce, and reaches the purpose of winning more.

The purpose of this utility model is achieved in that

A kind of universal die set for fixed mould is provided with a plurality of T type grooves and passes for T type bolts and cooperate pressing plate and pressure regulating screw with fixed mould on the mould bases surface; It is characterized in that: this T type groove is by being constituted with the elongated hole that is connected with this deep hole from the extension downwards of mould bases surface at the set deep hole of mould bases side, this deep hole and this slotted hole joint form a compression face that contacts with arc surface, and the cylinder confession bolt of a ccontaining tool horizontal screw is spirally connected as the T type nut of this T type groove in the hole in.And

This elongated hole can have a segment distance with the side of this mould bases, or side is opened the T type groove that the formation side has concane gap.

Form by above-mentioned structure and element, the utility model with commonly use mould bases and compare and have following advantage:

1, being subjected to the pressurized place of powerful drawing is arc surface, makes it significantly to dwindle the phenomenon that stress is concentrated, and has avoided being easy to generate the defective of being out of shape or being easy to generate the sharp-pointed interior re-entrant angle of rhegma, for the intensity of promoting this T type groove better effects is arranged.

2, effectively gentle pressurized and improve intensity, the arc surface of its pressurized to the distance on the surface of mould bases can moderate reduction, can shorten process time and reduce thickness and cost.

3, this T type groove is a milling elongated hole again behind subdrilling one deep hole, only needs twice processing to get final product, and can effectively reduce the processing cost of T type groove.

4, the side of the elongated hole of T type groove and mould bases leaves suitable distance, can not make each limit of mould bases produce concane gap, also can not reduce the bulk strength of mould bases, for material cost, processing cost, overall weight, even all appropriateness reductions again of working power.

5, built-in cylinder, it is all quite convenient and with low cost no matter to be that material is obtained and processed, and its tolerance nargin of inserting can have the bigger scope of application, in the future repair and replacement or use suitable convenience is arranged.

6, if this T type groove is positioned at the mould bases lower end of vertical, can prevent effectively that by the elongated hole that does not penetrate into side the mould of clamping from directly dropping under loosening state, for safe in utilization the bull point guarantee arranged.
