Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Specific implementations of the present invention are described in detail below with reference to specific embodiments.

Referring to fig. 1 to 4, a jig for placing PC sheets on a silica gel mold according to an embodiment of the present invention includes a set of horizontally disposed cavity-type fixing plates 1, two sets of handles 10 are fixedly embedded above the fixing plates 1, a parallel pressing plate 2 is disposed below the fixing plates 1, a plurality of air suction pipes 4 are connected between the fixing plates 1 and the pressing plate 2, and a plurality of angle plates 5 for placing PC sheets are fixedly embedded at the lower end of the pressing plate 2;

wherein, the upper end of the fixing plate 1 is provided with two groups of connecting air nozzles 3 communicated with the inner cavity of the fixing plate 1.

It should be noted that: the connecting air nozzle 3 arranged on the fixing plate 1 can be externally connected with an air pipe, so that air in the cavity inside the fixing plate 1 is extracted, and the pressure intensity inside the fixing plate 1 is adjusted in such a way;

it should also be noted that: the platen 2 is a main structure that is in contact with the mold and is placed on the mold so that the corner plate 5 on the lower end face thereof faces in the direction along the inside of the mold to guide the PC sheet placed inside into the mold;

in the present embodiment: the material of the air intake pipe 4 is preferably metal because of the hard pipe body.

In the embodiment of the present invention, referring to fig. 4, the lower end surface of the angle plate 5 is an inclined surface, an included angle of 30 ° is formed between the inclined surface and the horizontal plane, an embedded groove 6 for placing a PC sheet is formed on the lower end surface of the angle plate 5, and an air hole 7 penetrating through the pressing plate 2 is formed at the bottom of the embedded groove 6.

It should be noted that: the style and the shape of the caulking groove 6 correspond to those of the PC sheet, so that the PC sheet can be directly placed in the caulking groove 6, and the PC sheet can be preliminarily fixed;

it should also be noted that: the lower end face of the angle plate 5 is an inclined face, and a 30-degree included angle is formed between the angle plate and the horizontal plane, so that when the flat bottom face in the mold is contacted, the angle plate 5 is not attached to the bottom face of the mold, and the contact trace is linear, so that a certain interval exists between the angle plate 5 and the bottom of the mold, and when a PC sheet is led out, the leading-out effect is better.

In the embodiment of the present invention, referring to fig. 1, fig. 2 and fig. 4, the upper end of the air suction pipe 4 is communicated with the fixing plate 1, the lower end extends into the air hole 7 formed on the pressing plate 2 and is slidably connected with the inner wall of the air hole 7, and the lower end surface of the air suction pipe 4 and the bottom of the caulking groove 6 are located on the same horizontal plane;

it should be noted that: the air suction pipe 4 is communicated with the inside of the fixing plate 1, so that when the air pressure in the fixing plate 1 is reduced, the air pressure in the air suction pipe 4 is also reduced, the adsorption force generated by the pipe orifice at the other end is larger, the other end of the air suction pipe 4 is positioned at the same horizontal plane with the bottom of the caulking groove 6, when a PC (polycarbonate) sheet is placed in the caulking groove 6, the PC sheet is tightly attached to the bottom of the caulking groove 6, so that the pipe orifice of the air suction pipe 4 can be blocked, and the adsorption force generated by the air suction pipe 4 can directly act on the PC sheet, so that the PC sheet can be firmly adsorbed, and the stability of the PC sheet is further enhanced;

it should also be noted that: the air suction pipe 4 and the pressure plate 2 are in sliding connection, so that the air suction pipe 4 can move along with the fixed plate 1 in the moving process, when the fixed plate 1 is pressed downwards, the air suction pipe 4 also moves downwards, and the PC sheet embedded in the embedding groove 6 is ejected, so that the air suction pipe 4 also serves as a main structure for ejecting the PC sheet;

it should also be noted that: when breathing pipe 4 adopts hard metal material, the condition of bending can not appear when ejecting PC piece, when the device often contacts with the mould moreover, can receive the influence of mould temple high temperature, and the melting point of metal material is on the high side, consequently is difficult to appear the condition of melting.

In the embodiment of the present invention, referring to fig. 1 and 3, a plurality of guide posts 8 penetrating through the fixing plate 1 are further fixedly embedded at the upper end of the pressing plate 2, the guide posts 8 are slidably connected with the fixing plate 1, a spring 9 is further disposed outside the guide posts 8, and the spring 9 is embedded with the fixing plate 1 and the pressing plate 2.

It should be noted that: the guide posts 8 mainly limit the fixing plate 1, so that the fixing plate 1 and the pressing plate 2 form an integral structure, and the sliding connection between the guide posts 8 and the fixing plate 1 does not affect the up-down movement of the fixing plate 1, and the springs 9 outside the guide posts 8 have good elasticity, so that after the fixing plate 1 is compressed, the device can be restored to the original state through the elasticity of the springs 9, so as to be convenient for the next use.

The working principle of the jig for placing the PC sheet in the silica gel mold provided by the utility model is as follows: when using the device, at first put the device, 2 ground with clamp plate up, later install the gomphosis of PC piece inside caulking groove 6, later external trachea is connected on connecting air cock 3, take out 1 inside gas of fixed plate, thereby reduce its inside atmospheric pressure, adsorb the PC piece through breathing pipe 4, after fixing good PC piece, laminate 2 with clamp plate inside the mould, later can disconnect- type air cock 3, 1 inside atmospheric pressure of balanced fixed plate, breathing pipe 4 does not produce external force to the PC piece this moment, then through compression fixed plate 1, make breathing pipe 4 move down and support out the PC piece, make it drop to inside the mould, thereby accomplish the operation of placing of PC piece.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
