[0033] After injection molding is completed, wait for molten plastic to solidify and cool down, and then demoulding can be carried out. When demoulding, female die plate 2 is first moved upwards to separate from pusher plate 3, then pusher plate 3 is pushed upwards by ejector mechanism 5, and then positioning cap 8 formed is pushed out by pusher plate 3.

[0034] The sealing positioning cap forming die for sealing packages can quickly and efficiently complete the production work of the positioning cap 8.

[0035] As shown in Figures 6-8 Further, the pouring system comprises a pouring opening 10 located on the upper sealing plate 1, the pouring opening 10 is in communication with a main runner 11 formed in the upper sealing plate 1 and the female mold plate 2; the lower surface of the female mold plate 2 and the upper surface of the pushing plate 3 are both provided with a shunt groove 12, the two shunt grooves 12 cooperatively form a shunt runner 13, the inlet end of the shunt runner 13 is in communication with the main runner 11, and the outlet end of the shunt runner 13 is in communication with the forming cavity 7. Further, the outer side of the pouring opening 10 is further provided with a positioning ring 14, and the pouring opening 10 is located at the center of the positioning ring 14.

[0036] The pouring opening 10 is used for injecting molten plastic into the forming cavity 7, and the positioning ring 14 installed on the outer side of the pouring opening 10 is used for positioning the pouring opening 10, so that the injection molding device can be conveniently and quickly connected with the pouring opening 10 to complete the injection molding work. When injection molding is performed, the opposite surfaces of the female mold plate 2 and the pushing plate 3 are tightly attached, at this time, the shunt grooves 12 located on the lower surface of the female mold plate 2 and the upper surface of the pushing plate 3 cooperatively form the shunt runner 13, and the molten plastic enters each forming cavity 7 through the shunt runner 13 to form the positioning cap 8.

[0037] As shown in Figure 7 and Figure 8 Further, the lower surface of the female mold plate 2 is provided with N×M recessed molds 20 in a matrix manner, and the male mold plate 4 is correspondingly provided with N×M convex molds 40. Further, the lower surface of the female mold plate 2 is provided with 2×4 recessed molds 20 in a matrix manner, and the male mold plate 4 is correspondingly provided with 2×4 convex molds 40.

[0038] The lower surface of the female mold plate 2 is provided with N×M recessed molds 20 in a matrix manner, wherein N and M are the number of rows and columns respectively, and different numbers of rows and columns of recessed molds 20 and convex molds 40 can be set according to actual demand during the production of the positioning cap 8, so as to meet the production needs.

[0039] As shown in Figures 6-8 Further, a plurality of guide columns 45 are uniformly arranged along the edge length on the male mold plate 4, and a plurality of guide column sleeves 46 are correspondingly arranged on the female mold plate 2 and the pushing plate 3, and the height of the guide column 45 is equal to the sum of the depths of the corresponding two guide column sleeves 46.

[0040] The guide column 45 and the guide column sleeve 46 function to provide accurate positioning for the female mold plate 2 and the pushing plate 3 during mold clamping, mold opening and demolding, to ensure that the recessed mold 20 and the convex mold 40 accurately fit to form the forming cavity 7 during mold clamping, to ensure that the moving direction of the female mold plate 2 and the pushing plate 3 will not deviate during mold opening, and to avoid damage to the device or the positioning cap 8.

[0041] AsFigures 3-5 As shown, further, the ejection mechanism 5 comprises a support plate 50, a push rod fixing plate 51 and an ejection bottom plate 52 arranged in sequence from top to bottom, a plurality of push rods 53 are uniformly arranged on the push rod fixing plate 51 along the side length, the support plate 50 is provided with a plurality of push rod holes 54 corresponding to the push rods 53 on the male die plate 4, the push rods 53 sequentially penetrate the push rod holes 54 on the support plate 50 and the male die plate 4 upwards and abut against the lower surface of the pushing plate 3; a spring 55 is further sleeved on the push rod 53 between the support plate 50 and the push rod fixing plate 51, and the push rod fixing plate 51 and the ejection bottom plate 52 are fixedly connected. Further, two die feet 60 are symmetrically arranged on the lower sealing plate 6, the push rod fixing plate 51 and the ejection bottom plate 52 are arranged between the two die feet 60, and the support plate 50 is fixed on the upper surface of the die feet 60 by bolts.

[0042] When the positioning cap 8 is cooled and formed in the forming cavity 7, demolding is needed, and in the demolding, the ejection mechanism 5 is driven by the driving mechanism at the bottom of the lower sealing plate 6 to work (the setting of the driving mechanism is well known to those skilled in the art, and will not be described here). In the ejection demolding, the ejection bottom plate 52 is directly pushed upward by the driving mechanism, the push rod fixing plate 51 is pushed upward by the ejection bottom plate 52, the push rod fixing plate 51 drives the push rod 53 to slide upward along the push rod hole 54, and the push rod 53 pushes the pushing plate 3 upward to complete the ejection demolding of the positioning cap 8.

[0043] The support plate 50 is fixed on the die feet 60 by bolts, so in the process of upward movement of the push rod fixing plate 51, the spring 55 is also constantly compressed. When the ejection is finished, the driving mechanism is recovered, the spring 55 releases the elastic potential energy, and then the push rod fixing plate 51 and the ejection bottom plate 52 are sent back to the initial position, preparing for the next ejection.

[0044] In the ejection, the formed product positioning cap 8 is ejected from the male die 40 by the pushing plate 3, and in the whole process, the parts of the positioning cap 8 are uniformly stressed, and the uneven stress will not cause product damage, improving the qualified rate of product production.

[0045] Further, the upper sealing plate 1 and the female die plate 2 are fixedly connected by bolts.

[0046] The complete working process of the sealing positioning cap forming die for sealing the package is as follows:

[0047] When the positioning cap 8 is produced by the sealing positioning cap forming die for sealing the package, the forming die is first installed, the pouring opening 10 is quickly connected with the injection molding device through the positioning ring 14 during installation, the ejection mechanism 5, specifically the ejection bottom plate 52 in the ejection mechanism 5, is installed in cooperation with the driving mechanism, and after installation is completed, the production of the positioning cap 8 can be prepared to start. The installation of the above-mentioned parts is the common knowledge of those skilled in the art, and will not be described here.

[0048] In the production of injection molding, first, the mold is closed, that is, the male die plate 4 is tightly attached to the opposite side of the push plate 3, the male die 40 is penetrated through the push plate 3 upward, so that the circular boss 42 and the ring boss 43 are above the push plate 3. It is also necessary to tightly attach the push plate 3 to the opposite side of the female die plate 2, so that the female die 20 completely covers the circular boss 42 and the ring boss 43 to form a molding cavity 7, and the distribution groove 12 cooperates to form a distribution channel 13. At this time, injection molding can be performed. When the female die plate 2, the push plate 3 and the male die plate 4 are closed, the guide column sleeve 46 can be moved up and down on the guide column 45 to complete the operation.

[0049] The molten plastic flows out of the injection molding device, enters the main flow channel 11 through the pouring port 10, and then enters the distribution channel 13 from the main flow channel 11, and is distributed to each molding cavity 7 through the distribution channel 13. After injection molding is completed, the molten plastic is cooled and formed, and then demolding and ejection work can be performed.

[0050] When demolding and ejection, the female die plate 2 is first moved upward by the guide column sleeve 46 and the guide column 45, and then the driving mechanism at the lower sealing plate 6 pushes the ejection mechanism 5 to work. During ejection and demolding, the driving mechanism directly pushes the ejection bottom plate 52 upward, the ejection bottom plate 52 pushes the push rod fixed plate 51 upward, the push rod fixed plate 51 drives the push rod 53 to slide upward along the push rod hole 54, and the push rod 53 pushes the push plate 3 upward to complete the ejection and demolding of the positioning cap 8.

[0051] The support plate 50 is fixed on the mold foot 60 by bolts, so that the spring 55 is continuously compressed during the upward movement of the push rod fixed plate 51. When the ejection is completed, the driving mechanism is recovered, the spring 55 releases the elastic potential energy, and then the push rod fixed plate 51 and the ejection bottom plate 52 are sent back to the initial position, preparing for the next ejection. Through the mold closing, injection molding, cooling and molding, demolding and ejection, and then mold closing, the continuous production of the positioning cap can be realized.

[0052] It should be noted that the orientation described in the present application, such as the orientation or position relationship indicated by up, down, left, right, front, back, etc. is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.
