Description

Technical Field

[0001] The utility model relates to the technical field of dry bag machines, in particular to an inner mold positioning structure of a dry bag machine. Background Art

[0002] The dry bag machine is a dry bag isostatic press, which uses a dry compression method to load powdered or granular raw materials into an elastic mold, and then polarizes and pressurizes the raw materials with high-pressure liquid or gas to form them.

[0003] The inner mold and the pressure head of the existing dry bag machine are generally positioned by the stopper. When the inner mold and the product inside are removed from the pressure head after molding, the inner mold needs to be lifted to separate from the pressure head. This method has little effect on ordinary granulated powders, but for some metal powders that have not been granulated in advance and have low water content and are difficult to mold, the mold lifting action can easily cause damage to the product that has been molded in the inner mold. Utility Model Content

[0004] In order to overcome the technical defect of the existing inner mold positioning structure of a dry bag machine that the molded product is easily damaged when the inner mold is removed, the utility model provides an inner mold positioning structure for a dry bag machine.

[0005] The utility model provides a dry bag machine inner mold positioning structure, comprising:

[0006] Inner mold sleeve;

[0007] A lower plug is sleeved in the lower end of the inner mold sleeve, and a receiving groove is provided on the bottom surface of the lower plug;

[0008] An elastic member, which is placed in the receiving groove and has an upper end abutting against the bottom of the receiving groove;

[0009] A positioning ball, the top of which is located in the receiving groove and abuts against the lower end of the elastic member, and the bottom of which protrudes below the receiving groove;

[0010] The pressure head has a slot on its top surface, and the bottom of the positioning ball is clamped in the slot under the action of the elastic member to achieve relative fixation of the lower plug and the pressure head.

[0011] Optionally, a first installation groove is formed on the bottom surface of the lower plug, a positioning sleeve is fixed in the first installation groove, and the positioning sleeve forms the accommodating groove.

[0012] Optionally, a second mounting groove is provided on the top surface of the pressing head, a positioning plate is fixed in the second mounting groove, the top surface of the positioning plate is flush with the top surface of the pressing head, and the card slot is opened on the top surface of the positioning plate.

[0013] Optionally, the positioning plate is provided with a positioning hole, and the positioning hole forms the card slot.

[0014] Optionally, a threaded process hole is opened on the bottom surface of the lower plug.

[0015] Optionally, the elastic member is a spring.

[0016] Optionally, the positioning ball is a steel ball.

[0017] Compared with the prior art, the technical solution provided by the utility model has the following advantages:

[0018] The dry bag type inner mold positioning structure provided by the utility model includes an inner mold sleeve, a lower plug, an elastic member, a positioning ball and a pressure head. The bottom surface of the lower plug is provided with a receiving groove, and the top surface of the pressure head is provided with a clamping groove. The top of the positioning ball is placed in the receiving groove and the bottom is elastically clamped in the clamping groove under the action of the elastic member. With the gravity of the lower plug, the lower plug and the pressure head can be relatively fixed, thereby realizing the relative fixation of the inner mold sleeve and the pressure head. When the inner mold sleeve needs to be removed, it is only necessary to move the inner mold sleeve horizontally. The positioning ball further compresses the elastic member under the action of the clamping groove extrusion force and is completely placed in the receiving groove, thereby releasing the relative fixation of the lower plug and the pressure head. When removing the inner mold sleeve, this structure only needs to move the inner mold sleeve horizontally, and does not need to lift the inner mold sleeve vertically, which can avoid the mold lifting action from causing damage to the formed product. In addition, the positioning ball can be automatically clamped or disengaged under the action of the elastic member, and installation and disassembly are also more convenient.

[0024] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the scheme of the utility model will be further described below. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] The specific embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 The present embodiment provides an inner mold positioning structure of a dry bag machine, comprising an inner mold sleeve 1, a lower plug 2, an elastic member 3, a positioning ball 4 and a pressure head 5.

[0028] The inner mold sleeve 1 is the same as the existing structure, the only difference is that when it is assembled on the pressure head 5, no stopper positioning is required, which will not be repeated here.

[0029] The lower plug 2 is sleeved in the lower end of the inner mold sleeve 1 , and a receiving groove 221 is formed on the bottom surface of the lower plug 2 .

[0030] Specifically, the lower plug 2 can be sleeved in the inner mold sleeve 1 by interference fit or other common methods.

[0031] Furthermore, a first mounting groove 21 is provided on the bottom surface of the lower plug 2, and a positioning sleeve 22 is fixed in the first mounting groove 21, and the positioning sleeve 22 forms the receiving groove 221. Since the receiving groove 221 is frequently pushed by the positioning ball 4, it is easy to wear. In this embodiment, a positioning sleeve 22 is additionally provided on the lower plug 2, and the positioning sleeve 22 forms the receiving groove 221, so that the positioning ball 4 and the lower plug 2 are isolated by the positioning sleeve 22. In this way, after wear occurs, only the positioning sleeve 22 needs to be replaced, and the structural cost is lower.

[0032] It should be noted that the inner diameter of the positioning sleeve 22 should be slightly larger than the diameter of the positioning ball 4 so that the lower plug 2 can contact the pressure head 5 when the positioning ball 4 is in the positioning state, thereby ensuring the stability of the structure.

[0033] Further, a threaded process hole 23 is provided on the bottom surface of the lower plug 2. When the lower plug 2 needs to be carried, a bolt can be screwed into the threaded process hole 23, and the lower plug 2 can be carried by the bolt, which is more convenient to operate.

[0034] The elastic member 3 is disposed in the receiving groove 221 and the upper end thereof abuts against the bottom of the receiving groove 221 .

[0035] Specifically, the elastic member 3 is a spring. In other embodiments, the elastic member 3 may also be a spring silicone column or a columnar structure made of other commonly used elastic materials.

[0036] It is easy to understand that the two ends of the elastic member 3 do not need to be connected to the bottom of the receiving groove 221 and the positioning ball 4, and they only need to abut against each other.

[0037] It is easy to understand that, since the receiving groove 221 is provided on the bottom surface of the lower plug 2 , the bottom of the receiving groove 221 is the top surface thereof.

[0038] The top of the positioning ball 4 is located in the receiving groove 221 and abuts against the lower end of the elastic member 3 , and the bottom thereof protrudes below the receiving groove 221 .

[0039] Specifically, the positioning ball 4 is a steel ball. In other embodiments, the positioning ball 4 can also be a copper ball or other spherical structures whose hardness and wear resistance can meet the use requirements.

[0040] It is easy to understand that the top and bottom of the positioning ball 4 are relative, and the top and bottom can be but are not limited to half of the positioning ball 4, and there can also be an intermediate part between the top and the bottom. The purpose of placing the top of the positioning ball 4 in the receiving groove 221 and the bottom extending out of the receiving groove 221 is to be able to be simultaneously engaged in the lower plug 2 and the pressure head 5, thereby achieving relative fixation of the inner mold sleeve 1 and the pressure head 5.

[0041] A slot 521 is formed on the top surface of the pressure head 5 , and the bottom of the positioning ball 4 is clamped in the slot 521 under the action of the elastic member 3 to achieve relative fixation of the lower plug 2 and the pressure head 5 .

[0042] Furthermore, the top surface of the pressure head 5 is provided with a second mounting groove 51, a positioning plate 52 is fixed in the second mounting groove 51, the top surface of the positioning plate 52 is flush with the top surface of the pressure head 5, and the clamping groove 521 is provided on the top surface of the positioning plate 52. Since the clamping groove 521 is frequently pushed against the positioning ball 4, it is easy to be worn. In this embodiment, a positioning plate 52 is additionally provided on the top surface of the pressure head 5, and the clamping groove 521 is provided on the positioning plate 52, so that the positioning ball 4 and the pressure head 5 are isolated by the positioning plate 52. In this way, after wear occurs, only the positioning plate 52 needs to be replaced, and the structural cost is lower.

[0043] Specifically, the positioning plate 52 is provided with a positioning hole, and the positioning hole forms a clamping groove 521. The clamping groove 521 is formed by machining the positioning hole, and the machining is simpler and more convenient.

[0044] The working principle of the inner mold positioning structure of the dry bag machine of this embodiment is as follows:

[0045] When in use, first install the positioning sleeve 22 into the receiving groove 221, install the positioning plate 52 onto the pressure head 5, then insert the spring into the positioning sleeve 22, then place the positioning ball 4 against the bottom end of the spring, and finally place the entire device onto the pressure head 5. When installing, the positioning ball 4 is engaged in the slot 521 through horizontal movement to achieve relative fixation of the inner mold sleeve 1 and the pressure head 5; when disassembling, the positioning ball 4 is disengaged from the slot 521 through horizontal movement to achieve relative freedom of the inner mold sleeve 1 and the pressure head 5.

[0046] The above is only a specific implementation of the utility model, so that those skilled in the art can understand or implement the utility model. Although detailed descriptions are given with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments, and they should all be covered by the protection scope of the claims.
