Specifically, the bag bottom 2 may be a straight structure or a convex structure. The bag bottom 2 of the convex structure has a better sealing effect than the bag bottom 2 of the straight structure.
The method for manufacturing the silica gel milk storage bag according to the embodiment of the present invention will be described with reference to fig. 1 to 5.
A method for manufacturing a silica gel milk storage bag comprises the steps of plugging a bag bottom 2 at an opening of a bag body 1, and then mutually bonding the bottom end of the bag body 1 and the bag bottom 2 to obtain the silica gel milk storage bag.
As shown in fig. 5, a method for manufacturing a silica gel milk storage bag comprises the following steps:
s1, injecting the flowing solid silica gel formed by high-temperature heating into the bag body mould until the flowing solid silica gel is cooled into solidified solid silica gel to form the bag body part 1; and the flowing solid silica gel is injected into the bag bottom die until the flowing solid silica gel is cooled into solidified solid silica gel to form a bag bottom 2;
s2, sleeving the bag bottom 2 on the bottom sleeve mold 4, sleeving the bag body part 1 on the bag bottom 2, supporting the bottom sleeve mold 4 assembled with the bag bottom 2 and the bag body part 1, and placing the bottom sleeve mold 4 into the main body mold 5;
s3, the main body mold 5 is conveyed to a glue injection heating bin, a glue injection pipe of the glue injection press is in butt joint with the glue injection hole 43 of the bottom sleeve mold 4, liquid silica gel is injected into the glue injection pipe, the liquid silica gel flows into the contact surface of the bag bottom 2 and the bag body 1 from the flow guide grooves 44 on the two sides of the glue injection hole 43, the bag bottom 2 and the bag body 1 are bonded at a preset temperature and in a preset time, the bonded bag bottom 2 and the bonded bag body 1 are taken out, and the molded silica gel milk storage bag is obtained after normal temperature cooling.
It can be understood that, firstly, liquid silica gel is respectively injected into the bag body mold and the bag bottom mold, and after the flowing solid silica gel is cooled into solidified solid silica gel, semi-finished products of the silica gel milk storage bag, namely, the bag bottom 2 and the bag body 1, are obtained. The bag bottom 2 of the semi-finished product is sleeved on the bottom sleeve mold 4 to be fixed, then the bag body 1 of the semi-finished product is sleeved on the bag bottom 2 assembled on the bottom sleeve mold 4, and the bottom sleeve mold 4 assembled with the bag bottom 2 and the bag body 1 is supported by hands or an auxiliary tool to be placed in the main body mold 5. Open the switch that the control conveyer belt removed, main part mould 5 arrives in the injecting glue storehouse of heating along direction of delivery, carry out the heating under temperature and the predetermined time of predetermineeing, liquid silica gel in the injecting glue pipe flows into injecting glue hole 43, flow into towards the guiding gutter 44 of the relative both sides of injecting glue hole 43 again, until the contact surface that reaches bag bottom 2 and bag body 1 is in order to carry out the silica gel bonding, the sealing connection of bag bottom 2 and bag body 1 has been realized, treat that the normal atmospheric temperature cooling obtains fashioned silica gel bag of storing up milk.
The steps for manufacturing the silica gel milk storage bag can solve the problems of low hardness and low rigidity of a silica gel semi-finished product, the bag body part 1 and the bag bottom part 2 are sequentially sleeved on the bottom sleeve mold 4 to provide a powerful supporting effect, the bottom sleeve mold 4 is placed into the main body mold 5, the bag body part 1 and the bag bottom part 2 can be bonded through high-temperature molding in the glue injection heating bin, demolding and taking out are facilitated, and the process difficulty is low.
Alternatively, the bottom cover mold 4 is detachably placed in the main body mold 5.
It can be understood that, because the bottom cover die 4 is detachably placed in the main body die 5, firstly, the bottom cover die 4 is convenient to take out and load the bag bottom 2 and the bag body 1, and then the bottom die sleeved with the bag bottom 2 and the bag body 1 is placed in the main body die 5 for subsequent silica gel injection; secondly, when the bottom cover die 4 is not used, the bottom cover die is placed in the main body die 5, so that the storage is convenient, and the space is saved.
Alternatively, as shown in fig. 3, in step S2, an annular channel 41 is formed between the edge end of the bag bottom 2 and the edge end of the injection portion 42 of the bottom cover die 4, the liquid silicone rubber flows into the annular channel 41 from the guiding groove 44, and after the liquid silicone rubber is solidified, the sealing portion 3 made of the liquid silicone rubber is adhered to the edge ends of the bag bottom 2 and the bag body 1.
It should be noted that, the sealing portion 3 made of liquid silicone rubber is adhered to the edge ends of the bag bottom portion 2 and the bag body portion 1 to form an integral structure, and the annular channel 41 facilitates the liquid silicone rubber to flow into the sealing portion 3. The sealing part 3 further enhances the sealing performance, and when the liquid milk is injected into the silica gel milk storage bag, the liquid milk is not easy to leak out from the bonding part, thereby being convenient for storage and use.
Specifically, as shown in fig. 4, in step S2, the bottom cover mold 4 assembled with the bag bottom 2 and the bag body 1 is held and placed in the main body mold 5, centered and aligned. It can be understood that the bottom sleeve mold 4 is placed in the middle, the position is correct, the butt joint of the glue injection pipe and the glue injection hole 43 is facilitated to be more accurate, and the liquid silica gel is not prone to side leakage.

Optionally, the preset temperature range is 130-160 ℃, the fluidity of the liquid silica gel is relatively good, and the normal-temperature cooling time for taking out the bonded bag body 1 and the bag bottom 2 is short. If the preset temperature is higher than 160 ℃, the liquidity of the liquid silica gel is weak, and the liquid silica gel is not favorable for flowing into the flow guide groove 44 from the glue injection hole 43; if the preset temperature is lower than 130 ℃, the waiting time for cooling is longer, and the production efficiency is reduced. Of course, in other embodiments of the present invention, the preset temperature may be adjusted according to actual requirements.
Optionally, the preset time range is 50s-60s, and the time period can not only ensure the glue injection effect, but also ensure the glue injection efficiency. Of course, in other embodiments of the present invention, the preset time can be adjusted according to actual requirements.
Optionally, a gap is provided between the injection portion 42 and the pressing cover of the glue injection pressing machine.
It should be noted that, because a gap is formed between the injection portion 42 and the press cover, the liquid silica gel can flow into the flow guide groove 44 from the glue injection hole 43 through the plane tables on both sides, and then flow into the contact surface between the bag bottom 2 and the bag body 1 and the annular channel 41 from the flow guide groove 44, and after cooling at normal temperature, the rim charge in the glue injection hole 43 and the flow guide groove 44 is cleaned.
Optionally, as shown in fig. 3, a handle 6 is provided on the bottom cover die 4, and an operator can lift the handle 6 to lift the bottom cover die 4.
