Description

Glass mold with automatic demolding function

Technical Field

The utility model belongs to the technical field of glass product technology, concretely relates to glass mold who possesses automatic drawing of patterns function.

Background

The glass mold is a special mold for molding glass products, and comprises an upper mold and a lower mold, wherein a mold cavity is formed by the opposite pressing of the upper mold and the lower mold, and the design and molding of the structure of the glass product are realized by utilizing a specific mold cavity structure. However, the existing glass mold generally has a problem of "difficult demolding", because the formed glass product is located in the mold groove of the lower mold, the glass product and the mold groove still have certain cohesiveness, and demolding needs to be completed by using a clamp, that is, the glass product is separated from the mold groove, and the problem in the process is that:

1. since the glass product is substantially embedded in the mold groove, the jig does not have sufficient holding space, resulting in long demolding time and low efficiency.

2. Because the bottom surface and the four sides of the glass product are both adhered to the die groove, the clamp needs to apply enough clamping force on the glass product to enable the glass product to be separated from the die groove, so that the clamp is very easy to damage the outside of the glass product in the demolding process, and the forming quality of the glass product is influenced.

Disclosure of Invention

The purpose of the invention is as follows: in order to overcome the defects in the prior art, the glass mold with the automatic demolding function is provided, the glass product can be automatically demolded when the upper mold is reset through the demolding clamping plate, the demolding efficiency is improved, the glass product is prevented from being damaged in the demolding process, and the molding quality of the glass product is guaranteed.

The technical scheme is as follows: in order to realize the above-mentioned purpose, the utility model provides a glass mold who possesses automatic drawing of patterns function, including bed die and last mould, be provided with the lower die cavity on the bed die, the peripheral undercut in bottom surface of lower die cavity forms the drawing of patterns groove, be provided with a plurality of drawing of patterns springs and connect the drawing of patterns splint on the drawing of patterns spring in the drawing of patterns groove, drawing of patterns splint are used for upwards extrusion glass product formation drawing of patterns, the bottom of going up the mould is provided with the module, go up module, last mould and lower die cavity formation becomes the die cavity, the bottom surface and the drawing of patterns splint phase-match of going up the module, it is used for pushing down drawing of patterns splint to the drawing of patterns inslot to go up the module.

Further, the bottom surface of going up the module and the top surface of drawing of patterns splint are the inclined plane design, go up the module when pushing down drawing of patterns splint, and the contact surface between them is the inclined plane of mutual matching for go up the module and can be more steady push down drawing of patterns splint.

Furthermore, the inclination angles of the bottom surface of the upper module and the top surface of the demoulding clamping plate are both 45 degrees.

Further, the side of drawing of patterns splint closely laminates with the lateral wall in drawing of patterns groove, is favorable to drawing of patterns splint to lift the glass product on the one hand more and realizes breaking away from, and on the other hand drawing of patterns splint and glass product possess very big contact surface, and drawing of patterns splint can not damage the appearance of glass product.

Furthermore, the top of the lower die and the bottom of the upper die are respectively provided with a positioning groove and a positioning block which are matched with each other, the positioning groove and the positioning block are matched with each other to have a good positioning function, and the die closing quality of the lower die and the upper die is ensured.

Has the advantages that: compared with the prior art, the utility model, utilize the slant elasticity of drawing of patterns spring to drawing of patterns splint, when making the mould upwards reset, drawing of patterns splint can grasp the glass product under the effect of elasticity, and exert to the glass product simultaneously and lift the power, because the glass product only contacts with the bottom surface in mould groove, so do not need very big power of lifting, thereby make drawing of patterns splint can lift the glass product with the same trend and break away from the mould groove bottom surface, realize automatic drawing of patterns, not only the drawing of patterns efficiency has been improved by a wide margin, and avoided using anchor clamps to carry out the drawing of patterns, the drawing of patterns in-process can not lead to the fact the harm to the glass product, the shaping quality of glass product obtains the guarantee.

Detailed Description

The present invention will be further clarified by the following description with reference to the attached drawings and specific examples, which should be understood as being merely illustrative of the present invention and not limiting the scope of the present invention, and modifications of various equivalent forms of the present invention by those skilled in the art after reading the present invention, all fall within the scope defined by the appended claims of the present application.

As shown in fig. 1-3, the utility model provides a glass mold who possesses automatic drawing of patterns function, including bed die 1 and last mould 2, be provided with lower die cavity 3 on the bed die 1, the peripheral undercut in bottom surface of bed die 3 forms drawing of patterns groove 5, drawing of patterns splint 6 on drawing of patterns spring 7 is provided with four drawing of patterns springs 7 and connects to the interior symmetry of drawing of patterns groove 5, the bottom of going up mould 2 is provided with module 4, go up module 4's bottom surface and drawing of patterns splint 6 phase-match, four drawing of patterns springs 7 are the slant and set up the spring in this embodiment, drawing of patterns splint 6 are connected and are also the slant setting on drawing of patterns spring 7, the bottom surface of going up the module and the inclined plane design that drawing of patterns splint are 45 degrees, drawing of patterns splint 6's side can closely laminate with drawing of patterns groove 5's lateral wall, be provided with constant head tank 9 and locating piece 8 that mutually matchs on the top of bed die 1 and the bottom of last mould 2 respectively.

As shown in fig. 1, the clamping process of the glass mold in the present embodiment is: the upper die 2 is moved downwards firstly, so that the positioning block 8 is in butt joint fit with the positioning groove 9, in the process, the upper die block 4 of the upper die 2 contacts and presses down the four demoulding splints 6, the four demoulding splints 6 are pressed down to the demoulding groove 5, the upper die block 4, the upper die 2 and the lower die groove 3 form a forming cavity 100, a blank is injected into the forming cavity 100 for forming, and finally a formed glass product 10 is obtained.

As shown in fig. 2, after the forming is completed, the upper mold 2 moves up to separate from the lower mold 1, at this time, the mold release clamping plate 6 separates from the downward pressing limitation of the upper mold block 4, due to the oblique elastic force of the mold release spring 7, the mold release clamping plate 6 moves upward against the mold release groove 5, after the mold release clamping plate 6 separates from the mold release groove 5, the formed glass product 10 is clamped, the four mold release clamping plates 6 respectively provide upward clamping force from four sides of the glass product 10, and because the contact surface between the glass product 10 and the lower mold groove 3 is only the bottom surface, the mold release resistance is greatly reduced, the glass product 10 can be easily separated from the lower mold groove 3, and finally, the glass product 10 can be directly taken out by using a common fixture.
