Description

Technical Field

[0001] The utility model relates to the technical field related to injection molding cooling, in particular to a multi-station turntable injection molding shoe material machine capable of cooling molds through water. Background Art

[0002] In the production process of injection molding machines, the injection process is the process of material transformation from liquid to solid, and from high temperature to room temperature. If the product is not cooled to a certain temperature and the mold is opened too early, the product will shrink and deform. The temperature drop mainly comes from the heat transfer in contact with the mold. The temperature of the material will be transferred to the mold, thereby generating mold temperature. In continuous production, when the mold temperature accumulates to a certain level, it will shrink and the surface will become wavy, resulting in quality that does not meet the requirements.

[0003] Traditional injection molding shoe material machines often use two stations to complete injection molding and cooling and shaping. The coordination of the two stations is generally through manual or automatic control. However, this production method cannot achieve uninterrupted injection and cooling work. Therefore, existing injection molding shoe material machines generally adopt a multi-station production method. However, as the number of stations increases, the cooling pipe and the mold are prone to entanglement, resulting in reduced cooling efficiency. Utility Model Content

[0026] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0027] See also Figures 1 and 2In an embodiment of the present invention, a multi-station turntable injection molding shoe material machine capable of cooling the mold through water includes a workbench 1, a placement groove 101, a clamping movable plate 4, a cylinder 6, a mounting seat 12, a material injection and melting mechanism, a clamping mechanism, a cooling structure and connecting parts.

[0028] For details, please refer to Figure 1 and Figure 2 ,include;

[0029] A mounting seat 12, on which a circular workbench 1 is provided, and the workbench 1 is rotatably connected to the mounting seat 12 via a rotating shaft;

[0030] The workbench 1 is provided with a plurality of placement grooves 101 equidistantly formed along the circumference, and each placement groove 101 is provided with a mold locking movable plate 4;

[0031] It also includes an injection and melt glue mechanism disposed above the mounting seat 12, and the injection and melt glue mechanism is communicated with the inner side of a clamping mechanism fixedly mounted on the mounting seat 12;

[0032] A cooling structure is provided at the middle position of the workbench 1, and a cylinder 6 is provided on the mounting seat 12 located between the rotating shaft and the clamping mechanism. The cylinder 6 is used to control the conduction with the connecting piece connected to the clamping movable plate 4 in the clamping mechanism.

[0033] In detail, in this embodiment, a multi-station turntable injection molding shoe material machine capable of cooling the mold through water as described in the utility model is used. When in use, one of the clamping movable plates 4 is controlled to move upward relative to the clamping mechanism and abut against the clamping mechanism, and then the injection and melt mechanism is started to work. After the heated and softened material is pressed into the mold on the clamping movable plate 4 for molding, the clamping movable plate 4 is controlled to be reset to the workbench 1 again. At this time, the cylinder 6 is controlled to work to restore the conduction of the connecting piece between the rotating shaft and the clamping structure, so that cooling water can enter the clamping movable plate 4 below the clamping structure. The softened material in the mold is cooled and shaped. After the cooling work is completed, the workbench 1 is controlled to rotate so that the cooled mold is rotated to the next workstation, and the clamping movable plate 4 equipped with an empty mold is rotated to the lower end of the clamping mechanism and the injection is started again. This cycle accelerates the rapid cooling and shaping of the softened material in the mold, while avoiding entanglement between the cooling structure and the mold, and does not affect the injection work in the clamping structure. The demoulding work can be achieved more easily to realize one-by-one and uninterrupted injection operations, further improving the production effect and quality of injection-molded shoe materials.

[0034] As a further solution to this problem, please refer to Figure 1The clamping mechanism includes a symmetrically arranged clamping plate 5 and a machine column 2 symmetrically arranged on the clamping plate 5. Both ends of the machine column 2 are fixed to the clamping plate 5 and the mounting seat 12 respectively by bolts.

[0035] An oil cylinder 3 fixedly connected to the mounting seat 12 is provided below the mold locking mechanism. The movable end of the oil cylinder 3 can pass through the placement slot 101 and drive the mold locking movable plate 4 located below the mold locking mechanism to move up and down.

[0036] Preferably, the mold locking fixed plate 5 can be molded and abutted with the mold locking movable plate 4, wherein the mold locking movable plate 4 is pushed by the oil cylinder 3 to perform the lifting work, and the mold locking movable plate 4 is moved up and molded with the mold locking fixed plate 5, so that a closed space is formed between the mold locking movable plate 4 and the mold locking fixed plate 5, ensuring that the softened material is pressed in the mold while preventing the softened material from falling outside the mold locking movable plate 4 during the injection process, and the separately arranged mold locking movable plate 4 and mold locking fixed plate 5 provide convenience for the subsequent demoulding work of injection molding.

[0037] It is worth noting that: in order to ensure the stability of the locking movable plate 4 during the lifting process and prevent the locking movable plate 4 from tipping over during the lifting, a squeeze plate is provided at the movable end of the oil cylinder 3. The size of the squeeze plate should not be too large and can be smaller than the size of the placement slot 101.

[0038] As a further solution to this problem, please refer to Figure 1 and Figure 2 The injection and melt mechanism includes a barrel 11, which is fixedly mounted on the mounting base 12 via a support frame 13. The output end of the barrel 11 is connected to the clamping plate 5. An auger is provided in the barrel 11, and the rotating shaft of the auger is driven to rotate by a motor 9 fixedly mounted on the support frame 13.

[0039] The material barrel 11 further comprises a hopper 10 , the discharge end of the hopper 10 being in communication with the feed end of the barrel 11 .

[0040] Specifically, after the above-mentioned clamping movable plate 4 is raised to close the mold with the clamping fixed plate 5, the motor 9 is started to work, the output shaft of the motor 9 is fixedly connected to the rotating shaft of the auger, and the output shaft drives the auger to rotate when it rotates. The spiral blades squeeze the softened material dropped from the hopper 10 into the barrel 11, and the softened material is pressed into the mold between the clamping fixed plate 5 and the clamping movable plate 4 for molding. After the injection is completed, the motor 9 is controlled to stop working, and the cylinder rod of the start-up cylinder 3 is retracted, so that the clamping movable plate 4 and the mold with the softened material are reset, and the conduction between the cooling structure and the clamping movable plate 4 under the clamping structure is controlled, so that the mold containing the softened material can be accelerated to be cooled and molded, and the cooling water can be guaranteed to be required on demand, so as to accurately consume water for cooling each mold.

[0041] As a further solution of the present invention, the cooling structure includes a guide pipe 8 fixedly arranged at the center position of the workbench 1, and a water valve is provided on the guide pipe 8, and the water valve establishes communication with the cylinder 6.

[0042] The connecting member includes a plurality of connecting pipes, and the connecting pipes are arranged equidistantly along the circumference of the workbench 1 , one end of the connecting pipe is connected to the clamping movable plate 4 , and the other end is connected to the guide pipe 8 ;

[0043] It also includes a water shut-off device 7 , which is arranged on the connecting pipe between the guide pipe 8 and the locking dynamic plate 4 .

[0044] To elaborate, after the mold injection in the above-mentioned clamping movable plate 4 is reset, the control cylinder 6 is operated to open the water shut-off device 7 between the rotating shaft and the clamping structure, and the water valve is operated at the same time, so that the water flows into the guide pipe 8, and the connecting pipe between the rotating shaft and the clamping structure conducted by the cylinder 6 flows into the clamping movable plate 4 below the clamping structure. Among them, when the workbench 1 rotates, the connecting pipe rotates synchronously with the mold, which can avoid entanglement between the cooling structure and the mold, and control the water consumption for cooling each mold.

[0045] It is worth noting that the connecting pipe is configured as a hose to ensure that the connection between the connecting pipe and the locking movable plate 4 is not affected after the locking movable plate 4 is raised or lowered, and the connecting pipe between the rotating shaft and the locking movable plate 4 includes a water inlet pipe and a water outlet pipe. A one-way valve is provided between the water inlet pipe, the water outlet pipe and the guide pipe 8, and two independent channels are provided in the guide pipe 8, which are respectively connected to the water inlet pipe and the water outlet pipe. After the cold water enters the locking movable plate 4 through the water inlet pipe, it contacts the outer wall of the locking movable plate 4 to take away the heat, and then flows out through the water outlet pipe.

[0046] It should be noted that during cooling, the flow of cold water is accelerated by using a pressure water flow through the provided air valve. After the cooling water enters the clamping dynamic plate 4, it contacts the outer wall of the mold, taking away the heat on the outer wall of the mold to speed up the cooling effect of the injection molded parts in the mold.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
