Description

Technical Field

[0001] This utility model belongs to the field of motor accessories technology, and relates to a TPE injection molding positioning and error prevention structure for a logo insert of an automotive floor mat mold. Background Technology

[0002] When injection molding TPE for logo inserts in car floor mat molds, the reliability of the logo insert's positioning is a key issue affecting product quality. Traditional molds typically use simple placement installation, lacking a dedicated positioning and error-proofing structure. When the injection molten metal is injected into the cavity at high pressure and high speed, the resulting impact force can easily cause the logo insert to detach from its preset position, resulting in problems such as lateral displacement, axial misalignment, or even flipping. This not only leads to distorted and blurred logo patterns on the molded floor mat product, but in severe cases, it can also cause the logo insert to be poorly bonded to the floor mat body, affecting the product's lifespan.

[0003] For example, a Chinese patent discloses a high tensile strength wear-resistant TPE environmentally friendly car floor mat injection molding mold [application number: 201921358591.4], which includes an upper mold and a lower mold. The upper mold and the lower mold are respectively provided with an upper molding surface and a lower molding surface that matches the upper molding surface. The upper molding surface and the lower molding surface are combined to form a molding cavity. The lower molding surface is provided with a first protrusion protruding towards the molding cavity in the middle. The lower molding surface is also provided with a second protrusion and a third protrusion protruding upward at the edge. The recessed part on the lower molding surface between the first protrusion, the second protrusion and the third protrusion forms a water guide channel. Summary of the Invention

[0004] The purpose of this utility model is to address the above-mentioned problems by providing a TPE injection molding positioning and error-proof structure for the logo insert of an automotive floor mat mold.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A TPE injection molding positioning and error-proof structure for a logo insert of an automotive floor mat mold includes an upper mold, a lower mold, and an insert mounting component for installation between the upper and lower molds. The lower mold has a protruding molding insert that matches the insert mounting component. The upper mold has an upper molding surface that matches the molding insert. The upper mold also has a positioning and error-proof structure for positioning the insert mounting component.

[0006] In the above-mentioned TPE injection molding positioning and error prevention structure for the LOGO insert of the car floor mat mold, after the insert is installed on the molding block, when the upper mold and the lower mold are closed, the top surface of the insert and the upper molding surface form the upper floor mat body molding cavity. The upper surface of the molding block is also provided with a lower positioning structure.

[0007] In the aforementioned TPE injection molding positioning and error-proof structure for the LOGO insert of the car floor mat mold, the insert mounting part is provided with an LGGO insert.

[0008] In the above-mentioned TPE injection molding positioning and error prevention structure for the LOGO insert of the car floor mat mold, the positioning and error prevention structure includes two positioning posts protruding from the upper molding surface, and the insert mounting part is provided with positioning grooves corresponding to the positioning posts.

[0009] In the above-mentioned TPE injection molding positioning and error prevention structure for the LOGO insert of the car floor mat mold, the lower positioning structure includes several positioning ribs protruding from the upper surface of the molding insert, and the positioning ribs can be inserted into the rib positioning groove on the surface of the insert mounting part.

[0010] In the above-mentioned TPE injection molding positioning and error prevention structure for the LOGO insert of the car floor mat mold, the molding insert is further provided with a corresponding insert molding protrusion, and the top of the LGGO insert abuts against the LGGO insert.

[0011] In the above-mentioned LOGO insert TPE injection molding positioning and error prevention structure of the car floor mat mold, the lower floor mat main body molding cavity is also provided with a floor mat surface anti-slip part molding structure that can form an anti-slip part on the surface of the insert mounting part, and the floor mat surface anti-slip part molding structure is connected to the outer edge of the upper floor mat main body molding cavity.

[0012] In the aforementioned TPE injection molding positioning and anti-misalignment structure for the LOGO insert of the car floor mat mold, the anti-slip part molding structure of the floor mat surface includes a block-shaped anti-slip molding component and a strip-shaped anti-slip molding component.

[0013] In the aforementioned TPE injection molding positioning and anti-misalignment structure for the LOGO insert of the car floor mat mold, the block anti-slip molding component includes several block anti-slip molding grooves recessed inward on the molding insert.

[0014] In the above-mentioned TPE injection molding positioning and anti-misalignment structure for the LOGO insert of the car floor mat mold, the strip-shaped anti-slip molding component includes several parallel strip-shaped anti-slip molding grooves that are recessed inward on the top of the molding insert.

[0016] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

Detailed Implementation

[0018] like Figures 1-4 As shown, a TPE injection molding positioning and error-proof structure for a logo insert of an automotive floor mat mold includes an upper mold 1, a lower mold 2, and an insert mounting member 3 for installation between the upper mold 1 and the lower mold 2. The lower mold 2 has a protruding molding insert 4 that is adapted to the insert mounting member 3. The upper mold 1 has an upper molding surface 5 that is adapted to the molding insert 4. The upper mold 1 also has a positioning and error-proof structure 6 for positioning the insert mounting member 3.

[0019] In this invention, the LOGO insert is pre-installed in the insert mounting part 3 that is compatible with the molding insert 4, and the insert mounting part 3 is positioned by the positioning and anti-misalignment structure 6 on the upper mold 1. When the mold is closed, the fixed insert mounting part 3 can be covered in the foot pad when the injection liquid is injected. In this way, the problem of LOGO insert displacement caused by impact during injection molding can be solved, and the stability of LOGO insert installation and injection molding accuracy can be improved.

[0020] Furthermore, after the insert mounting part 3 is installed on the molding insert 4, when the upper mold 1 and the lower mold 2 are closed, the top surface of the insert mounting part 3 and the upper molding surface 5 form the upper foot pad main body molding cavity. The upper surface of the molding insert 4 is also provided with a lower positioning structure 7. By adding a lower positioning structure to the upper surface of the molding insert, a double positioning cooperation is formed with the positioning and anti-misalignment structure of the upper mold. During injection molding, the insert mounting part is double positioned and constrained, which further enhances its anti-displacement ability under the impact of the injection liquid, avoids positional deviation caused by insufficient positioning in one direction, and ensures the molding stability of the upper foot pad main body molding cavity.

[0021] Specifically, the insert mounting component 3 is fitted with an LGGO insert 8. By embedding and fixing the LOGO insert onto the insert mounting component, the LOGO insert obtains a stable mounting carrier, avoiding direct exposure to the injection molding liquid's impact environment. This design reduces the direct contact and impact between the LOGO insert and the injection molding liquid, lowers the risk of insert displacement, and ensures that the LOGO insert remains in a fixed position during injection molding, improving the integrity and accuracy of the molded LOGO.

[0022] Specifically, the positioning and error-prevention structure 6 includes two positioning posts 9 protruding from the upper molding surface 5, and the insert mounting component 3 is provided with positioning grooves 10 corresponding to the positioning posts 9. The positioning and error-prevention structure adopts a corresponding fit design between the positioning posts and the positioning grooves to achieve rapid and accurate alignment between the insert mounting component and the upper mold. This concave-convex fit structure can effectively limit the horizontal displacement of the insert mounting component, prevent lateral offset caused by the impact of injection molding liquid, and at the same time have an installation error-prevention function to avoid reverse or misaligned installation of the insert mounting component, thereby improving assembly efficiency and injection molding qualification rate.

[0023] Specifically, the lower positioning structure 7 includes several positioning ribs 11 protruding from the upper surface of the molded insert 4. These positioning ribs 11 can engage with the rib positioning grooves 16 on the surface of the insert mounting member 3. The lower positioning structure employs an engaging design between the positioning ribs and the rib positioning grooves, ensuring tight circumferential and radial positioning between the insert mounting member and the molded insert. This engaging structure increases the contact constraint area between the two, enhances the impact resistance of the insert mounting member, prevents torsion or displacement caused by uneven force during injection molding, and ensures the positional stability of the insert mounting member on the molded insert. The rib positioning grooves can also be used as drainage channels later.

[0024] Specifically, the molding insert 4 also has protruding insert molding protrusions 12 corresponding to the LGGO insert 8, with the top of the LGGO insert 8 abutting against it. By setting insert molding protrusions on the molding insert corresponding to the LOGO insert and abutting against the top of the LOGO insert, the LOGO insert is axially supported and positioned. This design limits the axial displacement of the LOGO insert under injection pressure, preventing it from sinking or shifting due to pressure, while ensuring the injection precision of the LOGO insert molding area and ensuring the clarity and integrity of the LOGO pattern.

[0025] Specifically, the lower foot pad's main body molding cavity also includes a foot pad surface anti-slip molding structure 13 that forms an anti-slip portion on the surface of the insert mounting component 3. This foot pad surface anti-slip molding structure 13 is connected to the outer edge of the upper foot pad's main body molding cavity. By adding this anti-slip molding structure to the lower foot pad's main body molding cavity and connecting it to the outer edge of the upper foot pad's main body molding cavity, the anti-slip portion of the foot pad is integrally molded while achieving precise positioning of the LOGO insert. This design eliminates the need for additional processing steps to create the anti-slip structure, improving production efficiency. Simultaneously, the connection between the anti-slip portion and the foot pad's main body is more secure, preventing later detachment and enhancing the performance of the foot pad product.

[0026] Specifically, the anti-slip molding structure 13 of the mat surface includes block-shaped anti-slip molding components and strip-shaped anti-slip molding components. The mat surface anti-slip molding structure adopts a combination design of block and strip-shaped anti-slip molding components, which can form diverse anti-slip patterns according to usage requirements. This combined structure enhances the anti-slip effect of the mat surface, adapts to anti-slip needs in different scenarios, enriches the structural diversity of the product, improves product competitiveness, and does not affect the positioning stability of the logo insert.

[0027] Specifically, the block-shaped anti-slip molding component includes several inwardly recessed block-shaped anti-slip molding grooves 14 on the molding insert 4. Through these recessed grooves, the block-shaped anti-slip molding component forms dispersed block-shaped anti-slip protrusions on the surface of the foot pad. These protrusions increase the friction between the foot pad and the contact surface, resulting in a significant anti-slip effect. Furthermore, the recessed molding groove design facilitates injection molding, and the molded block-shaped anti-slip structure is robust and resistant to wear. Simultaneously, it does not interfere with the LOGO insert positioning structure, ensuring overall molding quality.

[0028] Specifically, the strip-shaped anti-slip molding assembly includes several parallel strip-shaped anti-slip molding grooves 15 recessed inwardly on the top of the molding insert 4. The strip-shaped anti-slip molding assembly uses several parallel recessed strip-shaped anti-slip molding grooves to form continuous strip-shaped anti-slip patterns on the surface of the foot pad. The parallel strip structure not only has good anti-slip performance but also guides liquid flow, preventing water accumulation from affecting the anti-slip effect. Furthermore, the strip-shaped molding grooves are easy to process and have high injection molding efficiency, ensuring the anti-slip function while maintaining the injection molding accuracy and structural stability of the LOGO insert area.

[0029] The working principle of this utility model is as follows: the LOGO insert is pre-installed in the insert mounting part 3 that is compatible with the molding insert 4, and the insert mounting part 3 is positioned by the positioning and anti-misalignment structure 6 on the upper mold 1. When the mold is closed, the fixed insert mounting part 3 can be covered in the foot pad when the injection liquid is injected. In this way, the problem of LOGO insert displacement caused by impact during injection molding can be solved, and the stability of LOGO insert installation and injection molding accuracy can be improved. By adding a lower positioning structure to the upper surface of the molding insert, a double positioning fit is formed with the positioning and anti-misalignment structure of the upper mold. During mold closing and injection molding, the insert mounting part is constrained by double positioning, which further enhances its anti-displacement ability under the impact of injection liquid, avoids position deviation caused by insufficient positioning in one direction, and ensures the molding stability of the upper foot pad main body molding cavity. By embedding and fixing the LOGO insert on the insert mounting part, the LOGO insert obtains a stable mounting carrier and avoids it being directly exposed to the injection liquid impact environment. The positioning and error prevention structure adopts a corresponding matching design of positioning pins and positioning grooves to achieve rapid and accurate alignment of the insert mounting part and the upper mold. The lower positioning structure adopts a snap-fit ​​design of positioning ribs and rib positioning grooves to form a tight circumferential and radial positioning between the insert mounting part and the molding insert. By setting the insert molding protrusion on the molding insert corresponding to the LOGO insert and making it abut against the top of the LOGO insert, the LOGO insert is axially supported and positioned. An anti-slip molding structure is added to the lower foot pad's main molding cavity, connecting to the outer edge of the upper foot pad's main molding cavity. This achieves precise positioning of the logo insert while integrally molding the anti-slip part of the foot pad. The anti-slip molding structure of the foot pad's surface uses a combination design of block and strip anti-slip molding components, which can form diverse anti-slip patterns according to usage requirements. The block anti-slip molding components form dispersed block anti-slip protrusions on the foot pad surface through several recessed block anti-slip molding grooves, while the strip anti-slip molding components form continuous strip anti-slip patterns on the foot pad surface through several parallel recessed strip anti-slip molding grooves.
