[0002] To balance aesthetics and user experience, children's simulated toilet seats generally feature a tapered design on the outer side, but this structure presents significant challenges for injection molding demolding. Traditional injection molds lack targeted core-pulling demolding mechanisms, resulting in the tapered section fitting tightly to the mold cavity. This can easily cause jamming during demolding, leading to low demolding efficiency and potentially causing scratches, deformation, or even damage to the molded part due to forced demolding, severely impacting product quality and production schedule.

[0003] For example, a Chinese patent discloses an injection mold for a child-adjustable toilet body [application number: 202121197736.4], which includes an upper template and a lower template. The upper template has an inwardly recessed molding groove, and the lower template has an outwardly protruding molding insert that matches the molding groove. The molding groove and the molding insert are combined to form a molding cavity. The molding insert and the molding groove have a toilet groove molding structure in the middle. The molding cavity also has several lifting groove molding structures arranged circumferentially along the toilet groove molding structure. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing an injection mold for a child-simulated toilet seat with a double-slider side core-pulling mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A child-simulated toilet injection mold with a double-slider side core-pulling mechanism includes an upper mold plate and a lower mold plate. The upper mold plate and the lower mold plate are respectively provided with an upper insert and a lower insert. Side molding inserts are symmetrically arranged on the left and right sides of the lower mold plate. The upper insert, the lower insert, and the two side molding inserts are combined to form an integral molding cavity. The side molding inserts can form an arc-shaped waist in the middle of the integral molding cavity. The front side of the lower mold plate is also provided with a front core-pulling mechanism that is inserted into the integral molding cavity. The lower mold plate is also provided with a translation drive assembly connected to the side molding inserts.

[0006] In the above-mentioned injection mold of a child simulation toilet with a dual slider side core-pulling mechanism, the translation drive assembly includes a first driver mounting base fixed to the side of the lower template, a horizontally arranged translation driver fixedly connected to the first driver mounting base, and the output shaft end of the translation driver connected to the side molding insert.

[0007] In the above-mentioned injection mold of a child-simulated toilet with a double-slider side core-pulling mechanism, the translation actuator is a hydraulic cylinder.

[0008] In the above-mentioned injection mold for a child-like toilet with a double-slider side core-pulling mechanism, the lower template is also provided with a side insert limiting structure.

[0009] In the above-mentioned injection mold of a child simulation toilet with a double slider side core pulling mechanism, the side insert limiting structure includes several first limiting plates horizontally arranged on the lower template, and the first limiting plates are inserted into the limiting groove at the bottom of the side molding insert.

[0010] In the above-mentioned injection mold of a child simulation toilet with a dual-slider side core-pulling mechanism, the front core-pulling mechanism includes a front core-pulling seat that is slidably disposed on the lower template, and a front molding insert that is inserted into the integral molding cavity is fixedly connected to the inner end of the front core-pulling seat.

[0011] In the above-mentioned injection mold for a child-like toilet with a dual-slider side core-pulling mechanism, a second driver mounting base is fixedly connected to the front side of the lower template, and a core-pulling driver connected to the front molding insert is fixedly connected to the second driver mounting base.

[0012] In the above-mentioned injection mold of a child simulation toilet with a double slider side core-pulling mechanism, the bottom sides of the front core-pulling seat are provided with limiting parts, and the lower template is also fixedly connected with a limiting pressure plate located on the upper side of the limiting parts.

[0013] In the above-mentioned injection mold of the child simulation toilet with a double slider side core pulling mechanism, the upper insert is also provided with three connecting column forming grooves recessed inward, and the connecting column forming grooves are provided with connecting column insertion hole forming rods.

[0014] In the above-mentioned injection mold of the child simulation toilet with a double slider side core pulling mechanism, the top of the upper insert is also provided with several vertically arranged cooling channels recessed inward.

Detailed Implementation

[0019] like Figures 1-5 As shown, an injection mold for a child-like toilet seat with a double-slider side core-pulling mechanism includes an upper mold plate 1 and a lower mold plate 2. The upper mold plate 1 and the lower mold plate 2 are respectively provided with an upper insert 3 and a lower insert 4. The lower mold plate 2 is symmetrically provided with side molding inserts 5 on its left and right sides. The upper insert 3, the lower insert 4 and the two side molding inserts 5 are combined to form an integral molding cavity 6. The side molding inserts 5 can form an arc-shaped waist 7 in the middle of the integral molding cavity 6. The front side of the lower mold plate 2 is also provided with a front core-pulling mechanism that is inserted into the integral molding cavity 6. The lower mold plate 2 is also provided with a translation drive assembly connected to the side molding inserts 5.

[0020] In this invention, the injection mold forms an integrated molding cavity by combining an upper insert, a lower insert, and symmetrically arranged side molding inserts. The side molding inserts can form an arc-shaped waist in the middle of the cavity. Combined with the translation drive assembly driving the side molding inserts and the front core-pulling mechanism, targeted molding and step-by-step demolding of the waist-shaped structure are achieved. This design solves the demolding difficulty problem caused by the fixed waist-shaped structure in traditional molds, improving demolding efficiency. At the same time, the integrated molding cavity ensures the overall molding quality of the toilet seat.

[0021] Specifically, the translation drive assembly includes a first driver mounting base 8 fixed to the side of the lower template 2. A horizontally arranged translation driver 9 is fixedly connected to the first driver mounting base 8, and the output shaft end of the translation driver 9 is connected to the side forming insert 5. The translation drive assembly uses a first driver mounting base to fix the horizontally arranged translation driver, whose output shaft is directly connected to the side forming insert. This structure achieves stable horizontal driving of the side forming insert, ensuring precise and smooth movement of the side forming insert during demolding, avoiding damage to the molded part due to unstable driving, further improving the reliability and efficiency of the demolding process, and reducing the demolding failure rate.

[0022] Specifically, the translation actuator 9 is a hydraulic cylinder.

[0023] Preferably, the lower template 2 is also provided with a side insert limiting structure. The side insert limiting structure provided on the lower template constrains the movement trajectory of the side forming insert. This design avoids the side forming insert from shifting or shaking during translation, ensuring that the side forming insert and other inserts accurately cooperate to form an integral forming cavity, ensuring the forming dimensional accuracy of the toilet seat waist section, and improving the overall structural stability of the mold.

[0024] Specifically, the side insert limiting structure includes several first limiting plates 10 horizontally arranged on the lower template 2. These first limiting plates 10 are inserted into limiting grooves at the bottom of the side forming insert 5. The side insert limiting structure, with its horizontally arranged first limiting plates inserted into the bottom limiting grooves of the side forming insert, forms a reliable sliding guide and limiting mechanism. This structure further improves the movement accuracy of the side forming insert, ensuring that it maintains precise fit with the forming cavity during repeated movements, avoiding forming defects caused by limiting failure, and extending the service life of the mold.

[0025] Specifically, the front core-pulling mechanism includes a front core-pulling seat 11 slidably disposed on the lower template 2, and a front molding insert 12 inserted into the integral molding cavity 6 is fixedly connected to the inner end of the front core-pulling seat 11. The front core-pulling mechanism drives the front molding insert to insert into the integral molding cavity through the slidably disposed front core-pulling seat, realizing the molding and core-pulling of the complex front structure of the toilet. This design solves the problem of inconvenient demolding of the front structure of traditional molds, realizes multi-directional step-by-step demolding, further reduces the overall demolding difficulty, and improves the integrity and demolding efficiency of the molded part.

[0026] Specifically, a second driver mounting base 13 is fixedly connected to the front side of the lower mold plate 2. A core-pulling driver connected to the front molding insert 12 is fixedly connected to the second driver mounting base 13. The core-pulling driver is fixed to the front side of the lower mold plate through the second driver mounting base and connected to the front molding insert, realizing the automated driving of core pulling of the front molding insert. This design replaces manual core pulling, improves the efficiency and accuracy of the core pulling action, reduces the error and time consumption caused by manual operation, and makes the entire demolding process more efficient and stable.

[0027] Those skilled in the art will understand that the core-pulling actuator can be a hydraulic cylinder, a pneumatic cylinder, or a linear motor, etc.

[0028] Preferably, the bottom of the front core-pulling seat 11 has protruding limiting portions on both sides, and a limiting pressure plate 14 located above the limiting portions is fixedly connected to the lower template 2. The limiting portions at the bottom of the front core-pulling seat cooperate with the limiting pressure plate on the lower template to form upper and lower limits on the front core-pulling seat. This structure ensures that the front core-pulling seat will not move up and down during sliding, ensuring the positional accuracy of the front molding insert in the molding cavity, avoiding defects in the front molding structure caused by the offset of the front core-pulling seat, and improving the stability of mold forming.

[0029] Specifically, the upper insert 3 is further recessed with three connecting post forming grooves 15, and connecting post insertion hole forming rods 16 are provided in the connecting post forming grooves 15. The connecting post forming grooves on the upper insert cooperate with the connecting post insertion hole forming rods to achieve the integral molding of the toilet connecting post and the insertion hole. This design can complete the molding of the connecting post structure without subsequent processing, simplifying the production process, improving production efficiency, and ensuring the connection strength and dimensional accuracy between the connecting post and the toilet body.

[0030] Specifically, the top of the upper insert 3 is also recessed inward and has several vertically arranged cooling channels 17. The vertical cooling channels on the top of the upper insert accelerate the heat dissipation during the molding process. This design shortens the cooling and curing time of the injection molded part, increases the production cycle, and at the same time, uniform cooling avoids shrinkage and deformation of the molded part caused by uneven cooling, ensuring the appearance quality and dimensional stability of the children's simulated toilet seat.

[0031] The working principle of this invention is as follows: the injection mold forms an integrated molding cavity through the combination of upper inserts, lower inserts, and symmetrically arranged side molding inserts. The side molding inserts can form an arc-shaped waist in the middle of the cavity. With the help of the translation drive component to drive the side molding inserts and the setting of the front core-pulling mechanism, the targeted molding and step-by-step demolding of the waist structure are realized. This design solves the problem of difficult demolding caused by the fixed waist structure in traditional molds, improves demolding efficiency, and at the same time, the integrated molding cavity ensures the overall molding quality of the toilet. The translation drive assembly uses a first driver mounting base to fix a horizontally positioned translation driver, whose output shaft is directly connected to the side molding insert. This structure achieves stable horizontal drive of the side molding insert, ensuring that the side molding insert moves accurately and smoothly during demolding, avoiding damage to the molded parts caused by unstable drive, further improving the reliability and efficiency of the demolding process, and reducing the demolding failure rate. The side molding insert limiting structure set on the lower template constrains the movement trajectory of the side molding insert. This design avoids the side molding insert from shifting or shaking during translation, ensuring that the side molding insert and other inserts accurately cooperate to form an integral molding cavity, ensuring the molding dimensional accuracy of the toilet seat waist section, and improving the overall structural stability of the mold. The side molding insert limiting structure adopts a design where a horizontally positioned first limiting plate is inserted into the bottom limiting groove of the side molding insert, forming a reliable sliding guide and limit. This structure further improves the movement accuracy of the side molding insert, ensuring that it can maintain accurate cooperation with the molding cavity during repeated movements, avoiding molding defects caused by limiting failure, and extending the service life of the mold. The front core-pulling mechanism drives the front molding insert into the integrated molding cavity through a sliding front core-pulling seat, realizing the molding and core-pulling of the complex front structure of the toilet. This design solves the problem of inconvenient demolding of the front structure of traditional molds, realizes multi-directional step-by-step demolding, further reduces the overall demolding difficulty, and improves the integrity and demolding efficiency of the molded part. The front side of the lower template is fixed with the core-pulling driver through the second driver mounting seat and connected to the front molding insert, realizing the automated driving of the front molding insert for core pulling. This design replaces manual core pulling, improves the efficiency and accuracy of the core pulling action, reduces the error and time consumption caused by manual operation, and makes the entire demolding process more efficient and stable. The limiting part at the bottom of the front core-pulling seat cooperates with the limiting pressure plate on the lower template to form the upper and lower limits of the front core-pulling seat. This structure ensures that the front core-pulling seat will not move up and down during the sliding process, ensuring the positional accuracy of the front molding insert in the molding cavity, avoiding defects in the front molding structure caused by the offset of the front core-pulling seat, and improving the stability of mold molding. The connecting post molding groove on the upper insert mates with the connecting post insertion hole molding rod, achieving one-piece molding of the toilet's connecting post and insertion hole. This design eliminates the need for subsequent processing, simplifying the production process, improving efficiency, and ensuring the connection strength and dimensional accuracy between the connecting post and the toilet body. The vertical cooling channel at the top of the upper insert accelerates heat dissipation during molding. This design shortens the cooling and curing time of the injection molded part, increasing the production cycle time. Uniform cooling also prevents shrinkage and deformation of the molded part due to uneven cooling, ensuring the appearance quality and dimensional stability of the children's simulated toilet.
