Description

Technical Field

[0001] The utility model relates to the technical field of the processing of probiotic packaging, and more specifically to a production mold for a split sand-grain packaging bottle. Background Art

[0002] Most of the existing probiotic powder products are mainly packaged in strip bags. There are some deficiencies in the strip bag packaging method: when consumers take the products, it is not easy to tear open the strip bag. After being torn open, the notch of the strip bag is small, which is not convenient for taking. The easy-tear opening of the strip is serrated, which is difficult to tear open, and the torn notch is incomplete, and the powder is not easy to pour out. The packaging with rounded corners solves the problem of difficult tearing, but the notch is too small after being torn open, which is also not convenient for taking. After researching the products, it is found that using a bottled product can well solve the above problems. The probiotic bottle body is divided into two parts, namely a bottle cap and a lower bottle body structure. The bottle cap of the probiotic has an upper bottle body below the conventional bottle cap, and is clamped between the upper bottle body and the lower bottle body, and a sealing structure is arranged at the clamping position. The cap and the upper bottle body are integrally formed. When in use, the sealing structure is first removed, and then the cap and the upper bottle body are separated by an external force to complete one-time taking.

[0003] The above-mentioned packaging bottle is small in volume. For the convenience of use, its outer wall has an anti-slip sand-grain structure. Using the existing mold, it is impossible to smoothly demold, which is easy to cause damage to the anti-slip sand-grain structure. When opening the mold, the change of the external force is easy to cause relative displacement of the lid on the mold core. Since the lid is not completely cooled, it causes damage and deformation to the lid buckle position.

[0004] Therefore, how to provide a production mold for a split sand-grain packaging bottle is an urgent technical problem to be solved by those skilled in the art. Summary of the Utility Model

[0024] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0025] Conventionally, to solve the problem of difficult product demolding, the mold core and the mold cavity are generally made into a conical shape along the demolding direction. However, the above method cannot meet the processing of packaging bottles with sand patterns. If the mold core is made into a conical shape, the friction force increases when the sand pattern of the packaging bottle is taken out, and the sand pattern structure is easily damaged. In view of this, according to the characteristics of the split sand pattern packaging bottle, the present utility model provides a solution:

[0026] First, taking the cap part of the sand pattern packaging bottle as an example, the production mold will be described. Refer to the attached Figures 1-4 , including: a static mold assembly and a moving mold assembly that cooperate with each other. The top of the static mold assembly has a glue inlet channel 101. In the glue inlet channel, a nozzle 1012 is fixed to the static mold assembly through a fastener 1013. A positioning ring 1011 is installed at the top of the glue inlet channel 101 to facilitate the injection of glue into the static mold by an injection molding machine. The bottom of the static mold assembly has a static mold A plate 3. A static mold insert 301 is installed in the static mold A plate 3 through a static mold pressing plate 303, and the static mold insert 301 communicates with the glue inlet channel 101. A concave cavity corresponds to the lower part of the static mold insert 301, and the shape of its bottom end is the same as the shape of the closed end of the product; there are two inclined guide posts 302 on both sides of the concave cavity;

[0027] The moving mold assembly, the top of the moving mold assembly has a moving mold B plate 5. A B plate insert 501 facing the concave cavity is installed on the moving mold B plate 5. An inverted cone structure is formed at the end of the B plate insert 501 relative to the inside of the product; among them, the B plate insert 501 is fixed to the moving mold B plate through a moving mold pressing plate 503.

[0028] The pushing assembly, the pushing assembly has a moving mold push plate 4. The moving mold push plate 4 is movable on the moving mold B plate 5. A first side slider 401 and a second side slider 402 for driving the two inclined guide posts 302 correspondingly are arranged at the top of the moving mold push plate 4 relative to the concave cavity. The first side slider 401 and the second side slider 402 have structures matching the sand pattern on the outer wall of the product on the product side. Among them, the first side slider 401 and the second side slider 402 are fixed and guided through a runner bar 404 located on the moving mold push plate 4.

[0029] Advantageously, wear-resistant blocks 407 are provided on the outer inclined surfaces of the first side slider 401 and the second side slider 402: when the sliders are closed, they are directly in inclined surface contact with the stationary mold A plate. The wear-resistant blocks 407 are added between them to protect the sliders, avoid slider wear, prevent loose mold closing, and prevent burrs on the product.

[0030] Thus, when the mold is opened, the bottle cap part remains stable with the inverted conical structure at the end of the B-plate insert 501, without being affected by the external force changes during mold opening. Finally, it is ejected by the moving mold push plate 4, ensuring the qualified rate of the product.

[0031] In the above embodiment, according to the anti-bending fatigue strength of the material selected for the product, the difference between the major diameter and the minor diameter of the inverted cone structure is 20 - 100 silk. Materials without elasticity are not suitable for the inverted cone structure.

[0032] In a specific embodiment of the present invention, for the packaging bottle cap and bottle body, pp material can be used, and the difference between the major diameter and the minor diameter of the inverted cone structure is 30 - 40 silk.

[0033] In an embodiment of the present invention, the stationary mold assembly further includes a stationary mold runner plate 2 and a stationary mold panel 1 that are sequentially located on the top of the stationary mold A plate 3. The stationary mold panel 1, the stationary mold runner plate 2, and the stationary mold A plate 3 are penetrated by stationary mold guide posts 102; the top of the stationary mold A plate 3 has a distribution channel communicated with the nozzle 1012, and the distribution channel corresponds to a plurality of the stationary mold inserts 301; that is, the present invention can simultaneously mold multiple products. Each stationary mold insert 301 corresponds to a concave cavity, and each concave cavity corresponds to molding one product. The stationary mold panel 1 is connected with a plurality of runner hook pins 106 towards the distribution channel.

[0034] Advantageously, in order to facilitate the removal of excess rubber material and reduce the influence of the rubber material on the product, the stationary mold panel 1 and the stationary mold runner plate 2 are hung and connected by a first pull rod 103, and the stationary mold runner plate 2 and the stationary mold A plate 3 are hung and connected by a second pull rod 104, and the hanging length of the second pull rod 104 is greater than the hanging length of the first pull rod 103.

[0035] The "hanging length" is the moving space of the pull rod left in the stationary mold A plate 3, which is realized by stepped hanging holes and the pull rod. For example, when the stationary mold runner plate 2 and the stationary mold A plate 3 are opened, the second pull rod 104 follows the stationary mold runner plate 2 upward. At this time, the bottom upper end surface of the second pull rod 104 will abut against the bottom surface of the large hole of the stepped hanging hole in the stationary mold A plate 3.

[0036] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] To ensure that excess rubber is removed before the product is molded, the present invention installs a rubber plug 105 between the static mold plate A 3 and the dynamic mold push plate 4 via a connector 107. The rubber plug's function is to prevent the static mold plate A from separating from the dynamic mold push plate during the dynamic mold's movement, ensuring that the product is separated from the runners first. Specifically, the static mold runner plate and the static mold plate A are separated first. Connector 107 can be a silver steel wire or a bolt, with the rubber plug 105 threaded through it. When the static mold plate A separates from the dynamic mold push plate, the rubber plug deforms. Both the rubber plug and the connector are consumable parts.

[0038] On the basis of the above embodiment, the movable mold assembly further includes: a movable mold foot 8 and a movable mold panel 9, wherein the movable mold foot 8 is fixed to the top of the movable mold panel 9, and the movable mold guide column 502 is located at the top of the movable mold foot 8, and it passes through the movable mold B plate 5 and the movable mold push plate 4 from the bottom upward in sequence, and extends upward to enter the static mold positioning hole of the static mold A plate; the lower end of the static mold guide column 102 can enter the movable mold push plate 4, the movable mold B plate 5 and the movable mold positioning hole corresponding to the movable mold foot 8; a pushing space is formed between the movable mold B plate 5 and the movable mold panel 9, and a support column 504 is provided in the pushing space, and an ejection hole 901 connected to the pushing space is provided on the movable mold panel 9, and the ejection hole 901 is staggered with the support column 504.

[0039] The pushing assembly also includes an upper ejector plate 6 and a lower ejector plate 7 located in the pushing space, corresponding to the ejection hole 901, and fixedly connected. The support column 504 passes through the upper ejector plate 6 and the lower ejector plate 7, and is supported at the bottom of the movable mold B plate 5. Its height is consistent with the height of the movable mold foot 8; a return pin 701 is fixed on the lower ejector plate 7, and a return spring 702 is provided at the bottom of the return pin 701. The return spring 702 is located between the spring hole of the movable mold B plate 5 and the upper ejector plate 6. The top of the return pin 701 passes through the movable mold B plate 5 and is fixed to the movable mold push plate 4.

[0040] The movable mold push plate 4 is provided with a push plate insert 403 , which is located outside the B plate insert 501 and at the bottom of the product.

[0041] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "linkage", "fixation", etc. shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication between two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0042] When the mold of the present utility model is opened, under the action of external force, the static mold runner plate 2 and the static mold A plate 3 are opened first to separate the product from the distribution runner and remove the excess rubber material. Then, the static mold panel 1 and the static mold runner plate 2 are separated to remove the runner ejector pin. Then, the moving mold push plate 4 and the static mold A plate are separated (a first guide post 405 is fixed on the moving mold push plate 4, and a second guide post 406 that cooperates with the first guide post is fixed on the static mold A plate, which plays a role in guiding and centering during the opening and closing of the moving mold push plate and the static mold A plate, especially during the closing process). Synchronously, the inclined guide post in the static mold A plate directly drives the slider to move by means of the inclination, so that the product is separated from the cavity. Then, the product is ejected by the pushing assembly, the ejector rod retracts, and the moving mold push plate is pulled back by the return spring. Then, the moving mold moves to close the mold, and so on in a cycle.

[0043] It is worth noting that a balance block 408 can be arranged between the moving mold push plate and the static mold A plate. The balance block can be fixed on the moving mold push plate, which can effectively protect the moving mold push plate and the static mold A plate from unbalanced die pressing during mold closing, and effectively protect the accessories such as the slider of the mold and the inserts of the static and moving molds.

[0044] The basic principles of the mold for the bottle body and the mold for the bottle cap are the same, except that the cavity shape and the insert structure need to be modified accordingly according to the structure of the bottle body.

[0045] The production mold of the present utility model can not only be used in the production of probiotic packaging bottles, but also in the production of packaging bottles similar to this packaging bottle, to solve the problem of difficult demolding.

[0046] In the description of this specification, the description with reference to terms such as "one embodiment", "some embodiments", "examples", "specific examples", or "some examples", etc. means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model.
