Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0036] The purpose of this invention is to provide a mold for an integrated clamping structure for chain-type plastic ampoules, which can reduce waste generated during the production process.

[0037] It should be noted that in this embodiment, the X direction in the attached figure is defined as the first direction, and the Y direction is defined as the second direction. The first direction and the second direction are perpendicular to each other.

[0038] To achieve the above objectives, the present invention provides the following technical solution:

[0039] Please see Figures 1 to 9 This embodiment provides a mold for a chain-type plastic ampoule bottle integrated clamping structure, including: a pair of main molds 100 and head molds 200. The main mold 100 has a bottle body cavity 110, and the head mold 200 has a bottle head cavity 210. The head mold 200 is attached to the upper side of the main mold 100, and the bottle head cavity 210 and the bottle body cavity 110 can form a complete bottle cavity. The upper side of the head mold 200 is movably provided with clamping plates 220, which are used to clamp the product in the bottle cavity when the two head molds 200 are opened.

[0040] Specifically, the main mold 100 and the head mold 200 are arranged in pairs, each mounted on an independent drive unit, with the head mold 200 positioned above the main mold 100. The inner side of the main mold 100 has a bottle body cavity 110 to form the preform into a plastic bottle body, while the inner side of the head mold 200 has a bottle head cavity 210 to form the preform into a plastic bottle head. During use, the head mold 200 rests against the upper side of the main mold 100, thus the bottle head cavity 210 rests against the upper side of the bottle body cavity 110. This allows the bottle body cavity 110 and the bottle head cavity 210 to form a complete plastic bottle cavity, thereby enabling the preform to be formed into a complete plastic bottle. It should be noted that, compared with the prior art, this application has a relatively movable clamping plate 220 on the top of the mold head mold 200. When the mold main mold 100 and the mold head mold 200 are closed and the preform is formed, the clamping plate 220 will directly clamp the top position of the product. That is to say, the clamping fixture is integrated inside the head mold, and the clamping part is the auxiliary forming part of the product, saving the waste material generated by the original clamping part and saving costs.

[0041] In other words, the mold includes a mold head mold 200, a mold main mold 100, and a clamping plate 220. The mold operation process is as follows: the mold main mold 100 closes, and the tube preform is formed into a bottle body in the bottle body cavity 110 of the mold main mold 100. After filling the formed bottle body, the mold head mold 200, located above the mold main mold 100, closes, and the tube preform is formed into a bottle head in the bottle head cavity 210 of the mold head mold 200. At this time, the bottle shape is formed. Then, the mold head mold 200 and the mold main mold 100 open at the same time. At the moment of mold opening, the clamping plate 220 has already completed the demolding action of the product, so the product is kept in the middle position of the mold.

[0042] In one possible implementation, the upper side of the mold head 200 is provided with a mounting groove 230, and the clamping plate 220 can be movably mounted into the mounting groove 230 along the first direction.

[0043] Specifically, such as Figure 6 and Figure 7 As shown, a recessed mounting groove 230 is provided on the upper side of the mold head mold 200. The mounting groove 230 is located in the auxiliary forming part of the product. The clamping plate 220 is movably installed in the mounting groove 230. In this way, the clamping plate 220 can save the waste material generated by the original clamping part when clamping the product.

[0044] In one possible implementation, two guide blocks 240 are fixedly provided on the upper side of the mold head mold 200, and the two guide blocks 240 are respectively located on both sides of the mounting groove 230. The clamping plate 220 is provided with guide grooves 221 on both sides in the second direction. The guide grooves 221 engage with the guide blocks 240 to guide the clamping plate 220 to move along the first direction.

[0045] Specifically, such as Figures 3 to 9 As shown, guide blocks 240 are respectively installed on the protrusions on both sides of the mounting groove 230 of the mold head mold 200, and the guide blocks 240 protrude inward by a certain distance. Correspondingly, the clamping plate 220 is provided with guide grooves 221 of the same thickness as the guide blocks 240 at the same height on both sides in the second direction. In this way, the clamping plate 220 will be stuck between the two guide blocks 240, and it can only move back and forth along the guide blocks 240.

[0046] In this embodiment, a push-pull cylinder can be provided on the drive device that drives the mold head 200 to move, and a connecting seat is connected to the end of the movable rod of the push-pull cylinder on the upper side of the clamping plate 220, so that the clamping plate 220 can move along the first direction.

[0047] In one possible implementation, a relief groove 222 is provided on one side of the two clamping plates 220 that are close to each other, and the cavity formed by the two relief grooves 222 gradually widens in the direction away from the main mold 100.

[0048] Understandably, when the top of the product held by the two clamps 220 needs to be removed, in order to facilitate the operator to remove the product conveniently and safely, a relief groove 222 with an upward opening and gradually widening is provided on the inner side of the clamps 220. In this way, the operator can easily fix the product in the space avoided by the relief groove 222, and then release the clamps 220.

[0049] In one possible implementation, a cooling channel is provided inside the clamping plate 220, and an inlet 223 and an outlet 224 communicating with the cooling channel are provided on the side of the clamping plate 220 away from the relief groove 222.

[0050] In this embodiment, in order to enable the part of the product held by the clamping plate 220 to achieve rapid cooling and shaping, a curved cooling channel is provided inside the clamping plate 220; correspondingly, an inlet 223 and an outlet 224 communicating with the cooling channel are provided on the rear side of the clamping plate 220; in this way, cooling water can enter the cooling channel through the inlet 223 so that the clamping plate 220 can always maintain a low temperature. When the clamping plate 220 holds the tube preform in a molten state, it can make the held part cool and harden rapidly; then the water in the cooling channel that has been heated will be discharged from the outlet 224 for re-cooling; this arrangement can enable the bottle to be held and demolded smoothly after the mold is opened.

[0051] In one possible implementation, a linear guide rail extending in a first direction is provided in the mounting groove 230, and a slider that cooperates with the linear guide rail is provided on the lower side of the clamping plate 220.

[0052] Understandably, in order to enable the clamping plate 220 to slide smoothly within the mounting groove 230, a linear guide rail extending in the first direction is provided on the bottom surface of the mounting groove 230, and a slider is installed on the lower side of the clamping plate 220 at the position corresponding to the linear guide rail. In this way, when the clamping plate 220 moves, it can move through the cooperation of the slider and the linear guide rail, thereby reducing the friction between the clamping plate 220 and the mounting groove 230, improving the smoothness of its movement, reducing the wear of the clamping plate 220, and thus extending the service life of the clamping plate 220.

[0053] In one possible implementation, two linear guide rails are arranged side by side in the mounting groove 230, and each linear guide rail is fitted with two sliders.

[0054] Furthermore, in order to ensure the stability of the clamping plate 220 during movement, multiple parallel linear guides can be evenly arranged in the mounting groove 230, and at least two sliders can be provided on each linear guide. This can ensure that the clamping plate 220 does not wobble in the up and down direction during movement to the greatest extent.

[0055] In one possible implementation, limit protrusions are provided at both ends of the linear guide rail to prevent the slider from disengaging from the linear guide rail.

[0056] Furthermore, in order to prevent the clamping plate 220 from dislodging from the mounting groove 230 when moving along the first direction, limit protrusions can be set at the extreme positions of both ends of the linear guide rail to prevent the slider from moving, thereby ensuring that the clamping plate 220 moves back and forth within a fixed range.

[0057] In one possible implementation, the two mold head molds 200 are respectively provided with a positioning protrusion 250 and a positioning groove 260 that cooperates with the positioning protrusion 250 on one side close to each other. The positioning protrusion 250 and the positioning groove 260 are used for positioning when the two mold head molds 200 are closed.

[0058] In this embodiment, to ensure the accuracy of the two mold head molds 200 during mold closing, that is, to ensure that the two mold head molds 200 are aligned without deviation, positioning protrusions 250 are provided on both sides of the inner side of one of the two mold head molds 200, and positioning grooves 260 with the same shape as the positioning protrusions 250 are provided at the corresponding positions of the other mold head mold. In this way, the cooperation between the positioning protrusions 250 and the positioning grooves 260 during mold closing will guide the movement path of the two mold head molds 200, thereby ensuring that the two can be accurately aligned and thus ensuring the quality of the product.

[0059] Similarly, the same settings can be made on the two inner sides of the main mold 100, without making specific limitations in this article.

[0060] In one possible implementation, the guide groove 221 is filled with grease.

[0061] Understandably, in order to reduce the friction between the clamping plate 220 and the guide block 240, this embodiment can fill the guide groove 221 with grease, thereby making the movement of the clamping plate 220 smoother.

[0062] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0063] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0064] The embodiments provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
