Description

Technical Field

[0001] This utility model belongs to the field of molds, specifically a baby food bowl mold. Background Technology

[0002] As a feeding tool specifically designed for infants and toddlers, the injection molding quality of baby food bowls is closely related to mold design. Baby food bowls have deep cavities and inverted structures, making smooth and damage-free demolding one of the core challenges in mold design. Infant products require extremely high surface finish, free of any burrs or defects, which necessitates an extremely smooth and precise mold cavity. During injection molding, if air cannot escape from the mold, it can lead to material shortages, burning, and other problems. Simultaneously, food-grade silicone may create weld lines when merging within the mold cavity, affecting the product's strength and appearance. Therefore, the mold must be designed with an effective venting system. Shortening the injection molding cycle is crucial for reducing production costs. The mold needs to be designed with efficient cooling channels to allow the molten plastic or silicone to cool and solidify quickly and evenly, shortening production time. Baby food bowl molds are mass-produced products, and their injection molds need to withstand thousands of mold opening and closing cycles and high-pressure injections; therefore, they must be manufactured using high-hardness, high-wear-resistant steel.

[0003] In summary, baby food bowl molds face multiple challenges, including complex demolding, high surface quality requirements, venting and weld line control, efficient cooling, and long service life and durability. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a baby food bowl mold that can solve the problem of difficult demolding, ensuring product quality while also guaranteeing the mold's lifespan and practicality.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A baby food bowl mold includes, in sequence, a heat insulation plate, an upper mold base plate, a concave mold fixing plate, a demolding plate, a core fixing plate, a lower mold base plate, and mold feet. The heat insulation plate is fixedly connected to the upper mold base plate, the upper mold base plate is fixedly connected to the concave mold fixing plate, the mold feet are fixedly connected to the lower mold base plate, the lower mold base plate is fixedly connected to the core fixing plate, and the demolding plate is fixedly connected to the core fixing plate.

[0007] The cavity mold fixing plate is provided with a left half mold, a right half mold and a sprue bushing. The left half mold and the right half mold constitute the cavity mold. The sprue bushing is located at the nozzle inside the trapezoid formed by the left half mold and the right half mold. The lower end of the sprue bushing is fixed on the stripping plate. The core is fixed on the core fixing plate. The upper end of the core passes through the stripping plate and is inserted into the cavity mold.

[0008] The die has beveled slots on both ends. A limit slider is fixed on the die fixing plate. The limit slider is embedded in the beveled slot and slides along the beveled slot. Several outwardly inclined guide posts are fixed on the die fixing plate. Guide grooves are opened on the upper ends of the left and right half of the die. The guide posts are inserted into the guide grooves. Springs are sleeved on the guide posts. The upper end of the springs abuts against the die fixing plate, and the lower end of the springs abuts against the bottom of the guide groove. Stroke grooves are opened on the beveled surfaces on both sides of the die. Height limiting blocks are fixed on the die fixing plate, embedded in the stroke grooves and sliding along the stroke grooves.

[0009] The heat insulation plate has a main gate fixed at its center, the upper mold base plate has a funnel at the corresponding position at its center, the cavity mold fixing plate has a hot runner, and the main gate, funnel, and hot runner are coaxially arranged from top to bottom to form an injection channel.

[0010] When the spring pushes the left and right half of the mold to move diagonally downwards, the stroke groove and the height limit block abut against each other, which prevents the die from detaching from the die fixing plate.

[0011] Furthermore, T-slots are opened at both ends of the die, and T-shaped fasteners that can be embedded in the T-slots are fixed on the core fixing plate.

[0012] The T-shaped fastener allows the left and right half molds to move horizontally as the die fixing plate moves upward. The limiting slider is fixed on the die fixing plate. As the die fixing plate moves upward, the left half mold is pressed downward by the spring. The left half mold will move to the left along the ejector plate, while the right half mold moves to the right, thus achieving lateral parting of the die.

[0013] Furthermore, the hot runner is provided with several surrounding feed cooling water channels.

[0014] Furthermore, the core is provided with several rings of core cooling water channels inside.

[0015] Furthermore, several cooling channels are formed on the inclined surfaces of both sides of the die. Cooling water (or oil temperature controller medium) is circulated in the cooling channels to cool the die and core, thereby controlling the mold temperature and ensuring stable injection molding cycle and product quality.

[0016] Furthermore, a spacer plate is fixed to the die fixing plate, and the spacer plate can abut against the outer side of the die. The spacer plate allows the die to be positioned more effectively.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] 1. Optimized demolding mechanism: Through the ingenious combination of inclined slot, limiting slider, spring and T-shaped fixing part, the horizontal automatic separation of the left and right halves of the concave mold is realized when the mold is opened, which effectively avoids the deformation and damage that may occur in the demolding process of deep cavity undercut structure products, and demolding is smooth and reliable.

[0019] 2. Highly efficient and uniform cooling system: Cooling water channels are set in key parts of the hot runner, core and die, which improves cooling efficiency, shortens the product molding cycle, and helps to improve the internal quality and dimensional stability of the product.

[0020] 3. Stable structure and long service life: The overall structure is reasonably laid out, the connection is solid, the guidance is precise, and the spacer plate ensures the mold closing accuracy. It is suitable for long-term mass production and effectively extends the service life of the mold. Attached Figure Description

[0030] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0031] like Figure 1The illustrated baby food bowl mold includes, in sequence, a heat insulation plate 1, an upper mold base plate 2, a concave mold fixing plate 3, a demolding plate 4, a core fixing plate 5, a lower mold base plate 6, and mold feet 7. The heat insulation plate 1 is fixedly connected to the upper mold base plate 2, the upper mold base plate 2 is fixedly connected to the concave mold fixing plate 3, the mold feet 7 are fixedly connected to the lower mold base plate 6, the lower mold base plate 6 is fixedly connected to the core fixing plate 5, and the demolding plate 4 is fixedly connected to the core fixing plate 5.

[0032] like Figures 2 to 8 As shown, the cavity mold fixing plate 3 is provided with a left half mold 32, a right half mold 33 and a sprue bushing 34. The left half mold 32 and the right half mold 33 constitute a cavity mold. The sprue bushing 34 is located at the nozzle inside the trapezoid formed by the left half mold 32 and the right half mold 33. The lower end of the sprue bushing 34 is fixed on the stripping plate 4. A core 35 is fixed on the core fixing plate 5. The upper end of the core 35 passes through the stripping plate 4 and is inserted into the cavity mold.

[0033] The die has beveled grooves 381 on both ends. A limiting slider 38 is fixed on the die fixing plate 3. The limiting slider 38 is embedded in the beveled groove 381 and slides along the beveled groove 381. Several inclined guide posts are fixed on the die fixing plate 3. The upper ends of the left half die 32 and the right half die 33 have guide grooves. The guide posts are inserted into the guide grooves. Springs 39 are sleeved on the guide posts. The upper end of the springs 39 abuts against the die fixing plate 3. The lower end of the springs 39 abuts against the bottom of the guide groove. Stroke grooves are opened on the beveled surfaces on both sides of the die. A height limiting block 312 is fixed on the die fixing plate 3, embedded in the stroke groove and sliding along the stroke groove.

[0034] The heat insulation plate 1 has a main gate 11 fixed at its center, the upper mold base plate 2 has a funnel 21 at the corresponding position at its center, and the cavity mold fixing plate 3 has a hot runner 31. The main gate 11, funnel 21, and hot runner 31 are arranged coaxially from top to bottom and form an injection channel.

[0035] When the spring 39 pushes the left half mold 32 and the right half mold 33 to move diagonally downwards, the stroke groove and the height limiting block 312 abut against each other, preventing the die from detaching from the die fixing plate 3. Both ends of the die have T-slots 37, and the core fixing plate 5 is fixed with T-shaped fasteners that can be embedded in the T-slots 37. The T-shaped fasteners allow the left half mold 32 and the right half mold 33 to move horizontally when the die fixing plate 3 moves upwards. The limiting slider 38 is fixed on the die fixing plate 3. The left half mold 32 will be pressed downwards by the spring 39 as the die fixing plate 3 moves upwards. The left half mold 32 will move to the left along the ejector plate 4, while the right half mold 33 will move to the right, thereby achieving lateral parting of the die.

[0036] The hot runner 31 is provided with several concentric feed cooling channels 311, the core 35 is provided with several concentric core cooling channels, and several mold cooling channels 8 are opened on the inclined surfaces on both sides of the die. Cooling water (or oil temperature controller medium) is circulated in the cooling channels to cool the die and core 35, so as to control the mold temperature, ensure the stability of the injection molding cycle and the quality of the product 36.

[0037] A spacer plate 310 is fixed on the die fixing plate 3, and the spacer plate 310 can abut against the outer side of the die. The spacer plate 310 allows for better positioning of the die.

[0038] like Figures 1 to 7 The core of the baby food bowl mold shown lies in the demolding and cooling system.

[0039] Injection molding process: The heated and molten material is injected through the main gate 11, enters the hot runner 31 through the funnel 21, and finally fills the cavity mold composed of the left half mold 32, the right half mold 33, and the gate bushing 34. After filling, the cooling system is activated, and the cooling medium is introduced into the cavity mold cooling channel 311, the core cooling channel 351, and the cooling channel 8 on the side of the cavity mold, so that the product 36 in the cavity mold cools and solidifies quickly and evenly.

[0040] Demolding process: After the product cools and solidifies, the die fixing plate 3 moves upward along with the moving mold part. At this time, the T-shaped fastener fixed on the die fixing plate 3 drives the left half mold 32 and the right half mold 33 to move upward together. Since the position of the limit block 38 is fixed, during the upward movement, the spring 39 pre-pressed in the inclined grooves 381 of the left and right half molds releases its elastic force, pushing the left and right half molds to move horizontally to the left and right sides respectively along the guide of the T-slot 37, realizing the lateral parting of the die. Subsequently, the solidified product 36 is wrapped around the core 35 and can be removed from the core manually or mechanically, completing the entire injection molding cycle.

[0041] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
