Description

Technical Field

[0001] This utility model relates to the field of automotive floor mat technology, specifically an automotive floor mat injection molding machine. Background Technology

[0002] Injection molding machines are a type of equipment that integrates mechanical, hydraulic, and electrical control. By injecting molten thermoplastic elastomers, polyvinyl chloride, or rubber into a mold, and then molding under high pressure and cooling and demolding, they can mass-produce complex-shaped car floor mats.

[0003] Chinese patent application number CN202323005426.X discloses a multi-color car floor mat and its injection mold, comprising a floor mat body with a raised and recessed pattern on the upper surface of the floor mat body, and an insert on the upper surface of the floor mat body at the raised and recessed pattern. The floor mat body and the insert are different colors, and the raised and recessed pattern and the insert combine to form a decorative pattern. The above-mentioned utility model uses an in-mold insert method to realize the multi-color pattern of the car floor mat, which can be produced using ordinary injection molds. Compared with multi-color floor mats using an integrated injection molding machine, it greatly saves investment costs, simplifies the mold structure, and has a reasonable structure and beautiful appearance, and can meet the personalized needs of consumers.

[0004] However, in the actual production process, each insert and logo on a car floor mat must be installed individually by workers on the mold, which results in a low degree of automation and is not conducive to large-scale production.

[0005] In summary, this utility model provides an injection molding machine for car floor mats to solve the above problems. Utility Model Content

[0006] This utility model provides an injection molding machine for car floor mats, which solves the problem of low automation in the installation of inserts and markings on car floor mats in the prior art by setting up an automatic installation component.

[0007] The specific technical solution of this utility model is as follows:

[0008] An injection molding machine for car floor mats includes a main body of the injection molding machine. A drive cylinder is arranged on the side of the main body of the injection molding machine. A pressing column is arranged below the drive cylinder. The output end of the drive cylinder is fixedly connected to the pressing column. A slide rail is arranged below the pressing column. Several matching parts are arranged above the slide rail. A mold is arranged below the slide rail. An installation groove is formed on the upper surface of the mold. A material discharge hole is formed at the end of the slide rail near the mold. A limit plate is arranged on the side of the material discharge hole.

[0009] In this invention, a drive cylinder is used to control the lifting and lowering of the pressing column. The factory can use an automated production line to place accessories for car floor mats, such as inserts and markings, onto a slide rail. The accessories slide naturally downwards along the slide rail until they reach the material drop hole. A limiting plate ensures that the size of the material drop hole is slightly smaller than the maximum cross-sectional size of the accessory, thus keeping the accessory above the material drop hole. Since the accessories are generally made of soft, elastic materials such as rubber, when the drive cylinder moves the pressing column downwards to press the accessory, the accessory undergoes a slight deformation, allowing it to pass through the limiting plate and fall downwards until it lands in the installation slot, completing the installation of the accessory. The cooperation between the limiting plate and the pressing column effectively controls the falling time of the accessory, facilitating the adjustment of mold movement and installation timing, and is beneficial for large-scale production.

[0010] In a preferred embodiment, a base is provided below the main body of the injection molding machine.

[0011] In a preferred embodiment, a support plate is provided below the side of the slide rail near the mold. One end of the support plate is connected to the base, and a release hole is provided at the end of the support plate near the material discharge hole.

[0012] In this invention, the size of the release hole is the same as that of the accessory, and it is used to correct the movement path of the accessory so that the accessory falls vertically downward.

[0013] In a preferred embodiment, a bracket is provided below the side of the slide rail away from the mold, and one end of the bracket is connected to the base.

[0014] In a preferred embodiment, a sliding plate is provided on the side of the mold, and a guide rail is provided below the sliding plate. The sliding plate is slidably connected to the guide rail, and the bottom end of the guide rail is fixedly connected to the base.

[0015] In this invention, the sliding plate and guide rail allow the mold to be moved directly to the injection molding station after the accessories are installed, which facilitates automated production and processing.

[0016] In a preferred embodiment, a mounting base is provided above the base, a lifting plate is provided on one side of the mounting base, a servo cylinder is provided below the lifting plate, the output end of the servo cylinder is fixedly connected to the lifting plate, and the bottom of the servo cylinder is connected to the base.

[0017] In this invention, the lifting plate is used to restrict the movement of the mold, so that the mold can be aligned with the mounting base when moving. Furthermore, after the mold has completed injection molding, the lifting plate can be lowered so that the mold can continue to move into the next process.

[0018] In a preferred embodiment, a first electric slide is provided at the bottom of the injection molding machine body, a first movable plate is slidably connected above the first electric slide, and an auxiliary track is slidably connected to the side of the first movable plate away from the first electric slide.

[0019] In a preferred embodiment, a second electric slide is provided above the first movable plate, the second movable plate is slidably connected to one side of the second electric slide, and an injection nozzle is provided on the side of the second movable plate away from the second electric slide.

[0020] In a preferred embodiment, a balance track is slidably connected to the bottom of the second movable plate, and the side of the balance track away from the second movable plate is fixedly connected to the first movable plate.

[0021] In this invention, the first electric slide and the second electric slide are mainly used to adjust the position of the injection nozzle, so that the injection molding machine has a certain degree of flexibility during operation, thereby adapting to various types of molds.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. This utility model achieves automatic delivery and descent control of supporting parts through the cooperation of a drive cylinder, a pressing column, and a limiting plate, thus solving the problem of low automation and unfavorable large-scale production in the prior art.

[0024] 2. This utility model utilizes the deformation characteristics of the supporting parts to ensure that they fall accurately and controllably into the installation groove of the mold, thereby reducing the intensity of manual operation and the error rate, and reducing the scrap rate.

Detailed Implementation

[0033] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0034] like Figure 1-7 As shown, this utility model provides an injection molding machine for car floor mats, including an injection molding machine body 1. A drive cylinder 3 is provided on the side of the injection molding machine body 1. A pressing column 4 is provided below the drive cylinder 3. The output end of the drive cylinder 3 is fixedly connected to the pressing column 4. A slide rail 5 is provided below the pressing column 4. Several supporting parts 51 are provided above the slide rail 5. A mold 6 is provided below the slide rail 5. An installation groove 61 is opened on the upper surface of the mold 6. A material discharge hole 53 is opened at the end of the slide rail 5 near the mold 6. A limit plate 54 is provided on the side of the material discharge hole 53.

[0035] A base 2 is provided below the main body 1 of the injection molding machine.

[0036] A support plate 52 is provided on the side of the slide rail 5 near the mold 6. One end of the support plate 52 is connected to the base 2, and a release hole 521 is provided on the end of the support plate 52 near the material discharge hole 53.

[0037] A bracket 55 is provided below the side of the slide rail 5 away from the mold 6, and one end of the bracket 55 is connected to the base 2.

[0038] A sliding plate 62 is provided on the side of the mold 6, and a guide rail 21 is provided below the sliding plate 62. The sliding plate 62 and the guide rail 21 are slidably connected, and the bottom end of the guide rail 21 is fixedly connected to the base 2.

[0039] A mounting base 22 is provided on the top of the base 2. A lifting plate 23 is provided on one side of the mounting base 22. A servo cylinder 24 is provided below the lifting plate 23. The output end of the servo cylinder 24 is fixedly connected to the lifting plate 23, and the bottom of the servo cylinder 24 is connected to the base 2.

[0040] The bottom of the injection molding machine body 1 is provided with a first electric slide table 11, and a first moving plate 12 is slidably connected above the first electric slide table 11. An auxiliary rail 13 is slidably connected to the side of the first moving plate 12 away from the first electric slide table 11.

[0041] A second electric slide 14 is provided above the first movable plate 12. A second movable plate 15 is slidably connected to one side of the second electric slide 14. An injection nozzle 16 is provided on the side of the second movable plate 15 away from the second electric slide 14.

[0042] The bottom of the second movable plate 15 is slidably connected to a balance rail 151, and the side of the balance rail 151 away from the second movable plate 15 is fixedly connected to the first movable plate 12.

[0043] The working principle of this utility model is as follows: The factory uses an automated production line to place the accessories 51 for car floor mats, such as inserts and markings, onto an inclined slide rail 5. Due to gravity, the accessories 51 slide naturally downwards along the slide rail 5 until they reach the material drop hole 53 at the end of the slide rail 5 near the mold 6. A limiting plate 54 ensures that the size of the material drop hole 53 is slightly smaller than the maximum cross-sectional size of the accessories 51. Utilizing the elasticity of the accessories 51 (e.g., made of rubber), they are held in place above the material drop hole 53, awaiting installation instructions.

[0044] When the mold 6 moves directly below the discharge hole 53, the drive cylinder 3 drives the pressing column 4 downward, applying pressure to the fitting 51 that is stuck at the discharge hole 53. Because the fitting 51 is elastic, it undergoes a slight deformation under pressure, thus passing through the limiting plate and falling into the mounting groove 61 on the upper surface of the mold 6, completing the positioning and installation. This invention uses dimensional differences and elastic deformation characteristics to control the timing of the falling of the fitting 51, avoiding premature or delayed discharge and ensuring synchronization with the movement rhythm of the mold 6.

[0045] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
