Abstract

The utility model aims at solving the technical problems of low production efficiency, discontinuous pressing process and low pressing forming quality of traditional formed moulds. In order to solve the above problems, a bidirectional pressing forming mould used for a unidirectional press is provided. The bidirectional pressing forming mould comprises a mould cavity, wherein the mould cavity is provided with an upper pressing head and a lower pressing head therein, the mould cavity is arranged on a movable backing plate; a middle part of the movable backing plate is provided with a fixing sleeve core corresponding to the lower pressing head, the movable backing plate is provided with an elastic body corresponding to the mould cavity therein. According to the bidirectional pressing forming mould of the utility model, the movable backing plate is adopted, and a lower sizing block needs not to be removed, thus synchronous and continuous process of bidirectional pressing can be well ensured, at the same time, forming uniformity of a product is effectively realized, forming process is reduced, and efficiency of labor is raised, thus the bidirectional pressing forming mould of the utility model has extremely high economic benefit and practical value.

Description

A kind of for the bidirectional pressed moulding mould on one-way press
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of for the bidirectional pressed moulding mould on one-way press.
Background technology
Mould is for the compacting of grinding tool, ceramic etc.As shown in Figure 1, moulding process generally first drops into powder 5 in cavity body of mould, adds parallels 3 on die cavity 4 tops of mould, and bottom adds lower padding iron 7; Then, by upper padding plate 1, mould seaming chuck 2 is exerted pressure, be pressed into the molded blank of regulation shape and size.
As shown in Figure 2, prior art molding mode transmits downward pressure by seaming chuck 2 and makes powder 5 pressurizeds, then the manual lower padding iron 7 of removing, exert pressure again, due to the existence in gap between die cavity 4 and lower bolster 8, push-down head 6 is moved up by reaction force, realizes the bidirectional pressed moulding of powder.First, owing to realizing at twice two-way compacting, cause twice pressure size there are differences, cause the consistent in density of powder thickness direction to be difficult to control; Secondly, because compacting is upwards to realize by removing parallels, remove in parallels process, mould is easily moved, and causes the uniformity of goods after moulding to be affected.Finally, the operation of removing parallels has increased labour intensity, has reduced production efficiency simultaneously.
Summary of the invention
The technical problems to be solved in the utility model is that traditional mould production efficiency is low, and pressing process is discontinuous, and compressing quality is low, for addressing the above problem, provides a kind of for the bidirectional pressed moulding mould on one-way press.
The purpose of this utility model realizes in the following manner:
For the bidirectional pressed moulding mould on one-way press, comprise die cavity, seaming chuck and push-down head are set in die cavity, described die cavity is arranged on dynamic backing plate; At described dynamic backing plate middle part, the fixed cover core corresponding with push-down head is set, the elastomer corresponding with die cavity is set in described dynamic backing plate.
Described dynamic backing plate comprises upper plate and lower plate, and upper plate middle part arranges fixed cover core, and fixed cover core is fixed in lower plate, between upper plate and lower plate, spring is set.
Described fixed cover core is connected with push-down head one.
Described fixed cover core is bolted in lower plate.
The position that contacts with fixed cover core at described upper plate is provided with step, and fixed cover core is stuck on step.
In described upper plate and lower plate, be provided with corresponding groove, spring is set in groove.
With respect to prior art, the utility model adopts dynamic backing plate, do not need to remove lower padding iron, ensure well synchronously carrying out continuously of two-way compacting, effectively realize the uniform in shaping of goods simultaneously, reduce molding procedure, improved efficiency, there is very high economic benefit and practical value.
Brief description of the drawings
Fig. 1 is the structural representation of prior art.
Fig. 2 is the structural representation that prior art is removed parallels.
Fig. 3 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 3, a kind ofly comprise die cavity 4 for the bidirectional pressed moulding mould on one-way press, interior seaming chuck 2 and the push-down head 6 of arranging of die cavity 4, described die cavity 4 is arranged on dynamic backing plate; At described dynamic backing plate middle part, the fixed cover core 11 corresponding with push-down head 6 is set, the elastomer 12 corresponding with die cavity is set in described dynamic backing plate.Dynamically backing plate comprises upper plate 9 and lower plate 10, and upper plate middle part arranges fixed cover core 11, and fixed cover core 11 is fixed in lower plate 10 by bolt 13, between upper plate 9 and lower plate 10, spring 12 is set.Described fixed cover core 11 is connected with push-down head 6 one.The position that contacts with fixed cover core 11 at described upper plate 9 is provided with step, and fixed cover core 11 is stuck on step.In described upper plate 9 and lower plate 10, be provided with corresponding groove, spring 12 is set in groove.
Upper padding plate 1 is also set on seaming chuck 2, by upper padding plate 1, seaming chuck 2 is exerted pressure, between upper padding plate 1 and die cavity 4, parallels 3 is set, the utility model has designed dynamic elasticity backing plate, and upper plate 9 has certain quality of fit with fixed cover core 11; Fixed cover core 11 end faces have the structure coordinating with mould push-down head 6, can realize with Multiple Type mould and supporting the use, and between upper plate 9 and lower plate 10, are connected by elastomer, realize two-way time and carrying out.
