When using the package assembly for package work, first, the part to be packaged is determined by the positioning cap, then the positioning frame is sleeved outside the positioning cap to position the position of the positioning cap, and then the positioning cap is removed. After the sealing cap 7 is filled with glue and placed in the positioning frame, the sealing cap 7 is removed after the sealing glue is cured, so that the sealing of the part is achieved. The structure of the sealing cap 7 is shown in Figure 1 The shape of the sealing cap 7 is special, and there is no special production tool for producing the sealing cap 7 at present. Only manual production can be used, which is low in efficiency. UTILITY MODEL CONTENTS

Then the mold closing, injection molding and mold opening work can be carried out again for the next production. The movement of the above-mentioned parts can be realized by common driving devices such as air cylinder, oil cylinder, motor, etc., which is not limited here.

[0031] The sealing cap forming mold for sealing package provided by the utility model realizes the rapid production of the sealing cap 7 by the cooperation between the convex mold plate 2 and the concave mold plate 3, the bowl-shaped convex mold 20 and the concave mold 31, which is convenient, fast and suitable for practical use.

Further, the lower fluid pipe 38 for fluid flow is also formed on the half die 30.

[0042] The upper fluid inlet pipe 12 and the upper fluid outlet pipe 13 arranged in the upper cover plate 1 are communicated through the cooling cavity 25 formed in the inner portion of the bowl-shaped male die 20. During use, the cooling fluid flows into the cooling cavity 25 from the upper fluid inlet pipe 12, and then flows out of the upper fluid outlet pipe 13 when the cooling cavity 25 is filled. The cooling fluid flowing into the fluid pipe can quickly take away the heat of the molten plastic in the molding cavity 6, so that the molten plastic is quickly cooled and formed, and the production speed of the sealing cap 7 is improved. The cooling cavity 25 mainly exchanges heat with the inner surface of the sealing cap 7, and the lower fluid pipe 38 mainly exchanges heat with the outer surface of the sealing cap 7.

[0043] Further, the upper cover plate 1 and the male die plate 2, and the lower cover plate 5 and the mounting plate 4 are fixedly connected through bolts.

[0044] The utility model will be further described in detail in combination with specific embodiments as follows:

[0045] Embodiment 1

[0046] When the sealing cap forming die is used to produce the sealing cap 7, the two half-molds 30 slide towards each other on the mounting plate 4 through the sliding groove 41 and the sliding block 37, and are combined to form the complete concave mold plate 3. The special-shaped groove 32 on the half-mold 30 is also combined to form the concave mold 31. The upper sealing plate 1 and the convex mold plate 2 move downwards, and the convex mold plate 2 abuts against the concave mold plate 3. When the convex mold plate 2 and the concave mold plate 3 are tightly combined, the bowl-shaped convex mold 20 extends into the concave mold 31, and the two are combined to form the forming cavity 6. Then, the injection molding is performed through the injection port 10 on the upper sealing plate 1.

[0047] After the injection molding is completed and the product is cooled and formed, the demolding is performed. When the demolding is performed, the upper sealing plate 1 and the convex mold plate 2 move upwards and are separated from the concave mold plate 3, and the bowl-shaped convex mold 20 is also separated from the concave mold 31. Then, the two half-molds 30 slide in the opposite direction and are separated, thereby completing the demolding of the product sealing cap 7. At this time, the sealing cap 7 can be taken out, and the production is completed. Then, the mold closing, injection molding, and mold opening operations can be performed again, and the next production is performed. When the mold closing and mold opening are performed between the convex mold plate 2 and the concave mold plate 3, the guide column hole 24 and the guide column 40 are combined, thereby providing accurate positioning between the convex mold plate 2 and the concave mold plate 3. A plurality of bowl-shaped convex molds 20 are arranged on the lower surface of the convex mold plate 2, and a plurality of concave molds 31 are correspondingly arranged. When the injection molding is performed, a plurality of sealing caps 7 can be produced at one time, thereby improving the production efficiency.

[0048] Example 2

[0049] On the basis of Example 1, Example 2 further provides the equipment structure and working principle for further improving the production speed of the sealing cap 7. The ladder-shaped groove 21 and the inclined guide column 22 are arranged on the convex mold plate 2, and the bowl-shaped convex mold 20 is arranged in the ladder-shaped groove 21. The rectangular side wing 36 is arranged at the bottom of the half-mold 30, the inclined guide hole 23 is arranged on the rectangular side wing 36, and the guide column groove 50 is arranged on the side wall of the mounting plate 4 and the lower sealing plate 5. When the components of the device are assembled, the inclined guide column 22 passes through the inclined guide hole 23 arranged on the rectangular side wing 36 and is connected with the half-mold 30, thereby achieving the transmission between the two. The specific transmission process is as follows: when the mold is closed, the convex mold plate 2 moves downwards, and the inclined guide column 22 moves downwards at the same time. The inclined guide column 22 moves downwards in the inclined guide hole 23, and the two rectangular side wings 36 move towards each other. The rectangular side wings 36 drive the half-molds 30 to combine with each other to form the concave mold plate 3.

[0050] Through the combination of the inclined guide column 22 and the inclined guide hole 23, the upward movement of the convex mold plate 2 can be converted into the horizontal movement of the concave mold plate 3, specifically the half-mold plate 30. Through one driving device, the mold opening and mold closing operations of the entire device can be completed, thereby improving the production speed and reducing the cost.

[0051] The upper sealing plate 1 is further provided with an upper fluid inlet pipe 12 and an upper fluid outlet pipe 13, which are communicated through a cooling cavity 25 opened in the inner part of the bowl-shaped punch 20. The half mold 30 is also provided with a lower fluid pipe 38 for fluid flow.

[0052] In use, the cooling fluid flows into the cooling cavity 25 from the upper fluid inlet pipe 12, and then flows out from the upper fluid outlet pipe 13 when the cooling cavity 25 is filled. The cooling fluid flowing into the fluid pipe can quickly take away the heat of the molten plastic in the molding cavity 6, so that the molten plastic is quickly cooled and molded.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that; it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; 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 of the present application.
