Description

Technical Field

[0001] This utility model relates to the field of nipple injection mold technology, specifically an injection mold for the production of baby nipples. Background Technology

[0002] Nipple injection molds are essential tools for producing baby nipples. They consist of a front mold and a rear mold, which, when closed, form the cavity of the nipple. The rear mold primarily shapes the main body of the nipple, while the front mold shapes the top, edges, and other details. However, existing nipple injection molds have some shortcomings, such as:

[0003] Application No. CN202221662826.0 describes a simulated nipple injection mold. This equipment enables the lifting component to lift the product slowly and evenly, thus avoiding scratches caused by rapid demolding and effectively ensuring the surface integrity of the product during demolding. However, in actual use, this equipment has difficulty cooling the injection material, which may cause the material to stick to the surface of the mold during the nipple molding process, leading to demolding failure.

[0004] Therefore, we propose an injection mold for the production of baby bottle nipples to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide an injection mold for the production of baby bottle nipples, in order to solve the problem mentioned in the background art that the current bottle nipple injection molds on the market have difficulty in cooling the material during the injection process, resulting in the failure of the mold to release due to adhesion.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an injection mold for producing baby pacifiers, comprising a device body and a mold platform disposed on the top of the device body, a lower mold disposed on the top of the mold platform, and a limiting shaft installed on the top of the mold platform, and a mold groove slidably connected to the top of the limiting shaft, and an injection port disposed on the top of the mold groove;

[0007] The device body has a drive mechanism at the bottom, and the right end of the drive mechanism is connected to an ejection mechanism and an air supply mechanism. The top of the ejection mechanism and the air supply mechanism are connected to the mold table. The ejection mechanism includes a first bevel gear, and the top of the first bevel gear meshes with a second bevel gear. The top of the first bevel gear is provided with a reciprocating threaded shaft, and the outside of the reciprocating threaded shaft is provided with a threaded sleeve, and the top of the threaded sleeve is provided with an ejection ring.

[0008] The drive mechanism drives the ejection mechanism, which in turn drives the workpiece to rise via the reciprocating threaded shaft after it has been shaped. This causes the threaded sleeve to push the ejection ring out of the workpiece for material removal. During the shaping process, the drive mechanism also drives the air supply mechanism, which delivers cold air to the injection mold cavity to cool the material. This prevents the material from sticking to the mold cavity or lower mold during the injection molding process.

[0009] As a preferred technical solution of this utility model, the main body of the device is fixedly connected to the drive mechanism, and the drive mechanism includes a drive motor. A first sprocket is provided on the right side of the drive motor, a chain is engaged on the outside of the first sprocket, and a second sprocket is engaged on the other end of the chain. Both the first sprocket and the second sprocket are provided with ratchet groups on their right ends.

[0010] The above technical solution enables the drive mechanism to operate more stably when driving the ejector mechanism or the gas delivery mechanism, thereby increasing the stability of the equipment during operation.

[0011] As a preferred technical solution of this utility model, the second sprocket is connected to the inside of the device body through a bearing seat, and the ratchet group includes a first ratchet, and the right end of the first ratchet is engaged with a second ratchet. The right end of the second ratchet is connected to a spring shaft, and the ratchet group at the right end of the first sprocket and the ratchet group at the right end of the second sprocket face opposite directions.

[0012] The above technical solution makes it easier for the drive motor to control the gas delivery mechanism or the ejection mechanism, thereby increasing the controllability of the equipment during operation.

[0013] As a preferred technical solution of this utility model, the right end of the first sprocket is fixedly connected to the first bevel gear through a ratchet assembly, and the second bevel gear is connected to the inside of the device body through a bearing seat, and the ejector ring is slidably connected to the inner side of the mold table.

[0014] The above technical solution can prevent the drive mechanism from deviating when driving the first bevel gear and the second bevel gear to rotate, thereby increasing the stability of the equipment during operation.

[0015] As a preferred technical solution of this utility model, the right end of the second sprocket is connected to the air supply mechanism through a ratchet assembly, and the air supply mechanism includes a third bevel gear, and a fourth bevel gear meshes with the bottom of the third bevel gear. A peristaltic pump rod is provided at the bottom of the fourth bevel gear, and a peristaltic pump housing is provided on the outside of the peristaltic pump rod. An extrusion tube is provided between the peristaltic pump housing and the peristaltic pump rod. The top of the extrusion tube is connected to the mold table, and a one-way valve is provided at the top of the extrusion tube.

[0016] The above technical solution makes it easier for the gas conveying mechanism to transmit cold air between the mold groove and the lower mold, thereby increasing the convenience of the equipment in shaping materials.

[0017] As a preferred technical solution of this utility model, a cold air box is connected to the rear end of the extrusion tube, and a first sealing shell is provided at the bottom of the mold groove, and a second sealing shell is provided at the top of the mold table. The first sealing shell can be sealed and fitted with the second sealing shell, and a vent hole is provided at the top of the mold groove.

[0018] The above technical solution enables the first sealing shell and the second sealing shell to be fitted together, thereby sealing the mold groove and the outside of the lower mold, preventing the leakage of cold air or materials, and increasing the sealing performance of the equipment during injection molding.

[0019] As a preferred technical solution of this utility model, the mold table is provided with an electric push rod inside, and the top of the lower mold is provided with a mold head, and the top of the electric push rod is fixedly connected to the mold head.

[0020] The above technical solution enables the equipment to eject the molded nipple by raising and lowering the mold head via an electric push rod, thereby ejecting the workpiece and making demolding more convenient.

[0021] Compared with the prior art, the beneficial effects of this utility model are: by driving the ejector mechanism through the drive mechanism, the workpiece can be molded and then the reciprocating threaded shaft drives the threaded sleeve to rise, thereby causing the threaded sleeve to drive the ejector ring to eject the workpiece for material removal. In addition, during the molding process, the drive mechanism can drive the air supply mechanism to run, thereby causing the air supply mechanism to transmit cold air to the injection mold cavity to cool the material, so that the material will not stick to the mold cavity or the lower mold during the injection molding process.

[0022] Furthermore, by setting up the first sealing shell and the second sealing shell, the first sealing shell and the second sealing shell can be fitted together to seal the outside of the mold groove and the lower mold, thereby preventing the leakage of cold air or materials and increasing the sealing performance of the equipment during injection molding.

[0023] Furthermore, by setting up an electric push rod and a mold head, the device can lift and lower the mold head when ejecting the molded nipple, thereby ejecting the workpiece. This makes demolding the device more convenient. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Example 1: To solve the problem of materials easily sticking to the mold in the prior art, the following solution is disclosed. Please refer to [link / reference]. Figures 1-5 This utility model provides a technical solution: an injection mold for the production of baby pacifiers, including a device body 1 and a mold platform 2 disposed on the top of the device body 1. The mold platform 2 is provided with a lower mold 7 on the top, and a limiting shaft 3 is installed on the top of the mold platform 2. A mold groove 5 is slidably connected to the top of the limiting shaft 3, and an injection port 4 is provided on the top of the mold groove 5.

[0033] The device body 1 has a drive mechanism at the bottom, and the right end of the drive mechanism is connected to an ejection mechanism and an air supply mechanism. The top of the ejection mechanism and the air supply mechanism are connected to the mold table 2. The ejection mechanism includes a first bevel gear 16, and the top of the first bevel gear 16 meshes with a second bevel gear 17. The top of the first bevel gear 16 is provided with a reciprocating threaded shaft 18, and the outside of the reciprocating threaded shaft 18 is provided with a threaded sleeve 19. The top of the threaded sleeve 19 is provided with an ejection ring 26.

[0034] The main body 1 of the device is fixedly connected to the drive mechanism, and the drive mechanism includes a drive motor 9. A first sprocket 10 is provided on the right side of the drive motor 9. A chain 11 is engaged on the outside of the first sprocket 10, and a second sprocket 12 is engaged on the other end of the chain 11. Both the first sprocket 10 and the second sprocket 12 are provided with ratchet groups on their right ends.

[0035] The second sprocket 12 is connected to the inside of the device body 1 through a bearing seat, and the ratchet group includes a first ratchet 13, and the right end of the first ratchet 13 is engaged with a second ratchet 14. The right end of the second ratchet 14 is connected to a spring shaft 15. The right end of the first sprocket 10 is fixedly connected to the first bevel gear 16 through the ratchet group, and the second bevel gear 17 is connected to the inside of the device body 1 through a bearing seat. The ejector ring 26 is slidably connected to the inner side of the mold table 2.

[0036] The right end of the second sprocket 12 is connected to the air supply mechanism via a ratchet assembly. The air supply mechanism includes a third bevel gear 20, and a fourth bevel gear 21 meshes with the bottom of the third bevel gear 20. A peristaltic pump rod 22 is provided at the bottom of the fourth bevel gear 21, and a peristaltic pump housing 23 is provided on the outside of the peristaltic pump rod 22. An extrusion tube 24 is provided between the peristaltic pump housing 23 and the peristaltic pump rod 22. The top of the extrusion tube 24 is connected to the mold table 2, and a one-way valve is provided at the top of the extrusion tube 24.

[0037] The extrusion tube 24 is connected to a cold air box 25 at its rear end, and the bottom of the mold groove 5 is provided with a first sealing shell 6, and the top of the mold table 2 is provided with a second sealing shell 8. The first sealing shell 6 can be sealed and fitted with the second sealing shell 8, and the top of the mold groove 5 is provided with a vent hole.

[0038] Example 2: This example discloses a workpiece ejection method, which differs from Example 1, as follows: Figure 6 As shown, the difference between this embodiment and embodiment 1 is that: the mold table 2 is provided with an electric push rod 27 inside, and the top of the lower mold 7 is provided with a mold head 28, and the top of the electric push rod 27 is fixedly connected to the mold head 28;

[0039] When the nipple workpiece is injection molded, the electric push rod 27 can be activated, which will drive the mold head 28 to rise and fall, so that the mold head 28 will push the workpiece at the top of the lower mold 7 out from the inside. Then the ejection mechanism set inside the main body 1 will push the workpiece out from the bottom, so that the nipple workpiece can be ejected from both the inside and the bottom during the ejection process.

[0040] Working principle: When using this injection mold for baby bottle nipple production, first connect the equipment to the power supply and the grid. Then, make the mold groove 5 fit with the lower mold 7 to form an injection groove. Injection is performed through the injection port 4 set at the top of the mold groove 5. Then, the drive mechanism drives the air supply mechanism to run, so that the air supply mechanism transmits cold air to the injection groove formed by the mold groove 5 and the lower mold 7 to cool and shape the material. After the nipple is injected, the drive mechanism drives the ejection mechanism to run, so that the first bevel gear 16 in the ejection mechanism drives the second bevel gear 17 to rotate. The top of the second bevel gear 17 also drives the reciprocating threaded shaft 18 to rotate, so that the reciprocating threaded shaft 18 drives the threaded sleeve 19 and the ejection ring 26 to rise and fall. The ejection ring 26 rises and falls at the bottom of the lower mold 7, so that the ejection ring 26 ejects the workpiece from the bottom and demolds it.

[0041] When the drive mechanism is running, the drive motor 9 will drive the first sprocket 10 to rotate in the forward direction, thereby engaging the ratchet group at the right end of the first sprocket 10, that is, engaging the first ratchet 13 and the second ratchet 14. This causes the second ratchet 14 to drive the spring shaft 15 to drive the first bevel gear 16 to rotate. Since the ratchet group at the right end of the first sprocket 10 and the ratchet group at the right end of the second sprocket 12 face opposite directions, the ratchet group at the right end of the second sprocket 12 will disengage, that is, the first ratchet 13 and the second ratchet 14 will disengage, and the second ratchet 14 will retract under the drive of the spring shaft 15.

[0042] When the drive motor 9 rotates in the reverse direction, the ratchet assembly at the right end of the second sprocket 12 will engage, causing the second sprocket 12 to drive the third bevel gear 20 to rotate, which in turn drives the fourth bevel gear 21 and the peristaltic pump rod 22 to rotate. This causes the peristaltic pump rod 22 to work with the peristaltic pump housing 23 to squeeze the extrusion tube 24, which in turn transfers the cold air stored inside the cold air box 25 to the mold groove 5 and the lower mold 7 to form an injection groove to cool the workpiece. Then, the excess gas is discharged through the vent at the top of the mold groove 5.

[0043] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
