Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, specifically to a material receiving and shaping device for injection molding production. Background Technology

[0002] Injection molded parts are plastic products formed by heating and melting plastic granules and injecting them into a mold cavity through the injection molding process, followed by cooling and solidification. They have advantages such as high efficiency, high precision, and mass production capability, and are widely used in many fields such as electronics, automobiles, medical, and consumer goods. After the injection molded parts are processed, they need to be cooled to facilitate subsequent transportation.

[0003] For example, the utility model patent disclosed in publication number CN214395290U discloses a cooling and shaping device for injection molded parts. This device includes a support assembly and a cooling assembly disposed on the support assembly. The support assembly also has a shaping assembly that cooperates with the cooling assembly. The shaping assembly includes a plurality of cylinders disposed on the support assembly and shaping molds corresponding to each cylinder. The shaping molds include a lower shaping mold disposed on the cooling assembly and an upper shaping mold disposed on each cylinder. The lower shaping mold is used to hold the injection molded part to be cooled. When the piston rod of the cylinder extends, the upper shaping mold and the lower shaping mold cooperate to limit the movement of the injection molded part. This application has the effect of preventing warping and deformation of the injection molded part during the cooling process.

[0004] Although the above-mentioned equipment can perform cooling and shaping operations on injection molded parts, the efficiency of cooling and heat exchange of injection molded parts is insufficient, and the degree of automation in unloading the cooled injection molded parts is also insufficient. Therefore, there is an urgent need for a material receiving and shaping device for injection molding production to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a material receiving and shaping device for injection molding production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a material receiving and shaping device for injection molding production, comprising a transmission device for support and transmission, wherein two sets of aluminum profile columns are symmetrically arranged on the upper end face of the transmission device, and two sets of motor mounts are arranged near the front of the lower end face of the aluminum profile columns, and a servo motor is arranged on the lower end face of the motor mounts.

[0007] A liquid-cooled guide plate is threadedly connected to the upper part of the transmission device, and a shaping upper mold is provided on the lower end face of the liquid-cooled guide plate. First cooling pipe docking seats are provided at the front and rear of the liquid-cooled guide plate, and two sets of threaded sliding sleeves are provided on the inner end face of the liquid-cooled guide plate.

[0008] A shaping device is threadedly connected to the upper end face of the transmission device near the middle, and the shaping device is used for heat dissipation and shaping.

[0009] Preferably, the shaping device includes a liquid-cooled base, a second cooling pipe docking seat is symmetrically arranged on the side end face of the liquid-cooled base, and two sets of threaded rotating sleeves are arranged on the inner end face of the liquid-cooled base. Shaping cavities are equidistantly opened on the upper end face of the liquid-cooled base, and a sealing groove is opened at the center of the lower end face of the shaping cavity.

[0010] Preferably, the transmission device includes a support bracket, with transmission screws rotatably engaged at the four corners of the inner end face of the support bracket, and synchronous pulleys are provided on the lower end faces of the four sets of transmission screws. The synchronous pulleys arranged diagonally are meshed and connected by synchronous belts. Three sets of linear sliding shafts are symmetrically arranged at equal intervals on the upper end face of the support bracket, and feeding guide seats are equidistantly arranged on the upper end face of the support bracket.

[0011] Preferably, the unloading guide seat and the sealing groove are sealed and slidably engaged, which facilitates the subsequent unloading of the cooled injection molded part through the sealing groove.

[0012] Preferably, the liquid-cooled base is threadedly connected to the transmission screw via the threaded rotating sleeve, and the liquid-cooled guide plate is threadedly connected to the transmission screw via a threaded sliding sleeve. The threaded connection between the threaded sliding sleeve and the transmission screw facilitates the subsequent up-and-down movement of the liquid-cooled guide plate via the threaded sliding sleeve, which facilitates the subsequent shaping and limiting of the upper part of the injection molded part. At the same time, the threaded connection between the transmission screw and the threaded rotating sleeve facilitates the subsequent unloading operation of the injection molded part.

[0013] Preferably, both the liquid-cooled guide plate and the liquid-cooled base are slidably engaged with the linear slide shaft. The linear slide shaft can provide sufficient guiding foundation for the liquid-cooled guide plate and the liquid-cooled base, thereby improving the stability of the liquid-cooled guide plate and the liquid-cooled base during vertical displacement.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting up a shaping device and a transmission device, enables the upper mold and the shaping cavity to be rigidly set during the shaping and cooling of batch injection molded parts. This allows for simultaneous shaping while cooling the injection molded parts, thereby improving the dimensional stability of the injection molded parts after cooling. At the same time, during automated unloading, the transmission screw can be threadedly connected to the threaded rotating sleeve to automatically unload the injection molded parts from the shaping cavity, effectively improving the convenience and automation of unloading the cooled injection molded parts.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides an embodiment of a material receiving and shaping device for injection molding production, including a transmission device 5 for support and transmission. Two sets of aluminum profile columns 6 are symmetrically arranged on the upper end face of the transmission device 5, and two sets of motor bases 8 are arranged near the front of the lower end face of the aluminum profile columns 6. A servo motor 7 is arranged on the lower end face of the motor base 8.

[0024] Liquid cooling guide plate 2 is threadedly connected to the upper part of transmission device 5, and a shaping upper mold 3 is provided on the lower end face of liquid cooling guide plate 2. First cooling pipe docking seat 1 is provided at the front and rear of liquid cooling guide plate 2, and two sets of threaded sliding sleeves 9 are provided on the inner end face of liquid cooling guide plate 2.

[0025] The shaping device 4 is threadedly connected to the upper end face of the transmission device 5 near the middle. The shaping device 4 is used for heat dissipation and shaping.

[0026] The shaping device 4 includes a liquid-cooled base 45. A second cooling pipe docking seat 44 is symmetrically arranged on the side end face of the liquid-cooled base 45, and two sets of threaded sleeves 43 are arranged on the inner end face of the liquid-cooled base 45. A shaping cavity 42 is equidistantly opened on the upper end face of the liquid-cooled base 45, and a sealing groove 41 is opened at the center of the lower end face of the shaping cavity 42.

[0027] The transmission device 5 includes a support bracket 56. The four corners of the inner end face of the support bracket 56 are rotatably engaged with transmission screws 53. Synchronous pulleys 54 are provided on the lower end face of the four sets of transmission screws 53. The two sets of synchronous pulleys 54 arranged diagonally are meshed and connected by synchronous belts 55. Three sets of linear sliding shafts 52 are symmetrically arranged at equal intervals on the upper end face of the support bracket 56. Feed guide seats 51 are equidistantly arranged on the upper end face of the support bracket 56.

[0028] like Figure 2 and Figure 3 The unloading guide seat 51 and the sealing groove 41 are sealed and slidably engaged, which facilitates the unloading guide seat 51 to drive the cooled injection molded part to perform a fast unloading operation through the sealing groove 41.

[0029] like Figure 1 and Figure 3 The liquid-cooled base 45 is connected to the transmission screw 53 via a threaded sleeve 43, and the liquid-cooled guide plate 2 is connected to the transmission screw 53 via a threaded sliding sleeve 9. The threaded connection between the threaded sliding sleeve 9 and the transmission screw 53 facilitates the subsequent vertical movement of the liquid-cooled guide plate 2 by the transmission screw 53 through the threaded sliding sleeve 9, which facilitates the subsequent shaping and limiting of the upper part of the injection molded part. At the same time, the threaded connection between the transmission screw 53 and the threaded sleeve 43 facilitates the subsequent unloading operation of the injection molded part.

[0030] like Figure 1 Both the liquid-cooled guide plate 2 and the liquid-cooled base 45 are slidably engaged with the linear slide shaft 52. The linear slide shaft 52 can provide sufficient guiding foundation for the liquid-cooled guide plate 2 and the liquid-cooled base 45, thereby improving the stability of the liquid-cooled guide plate 2 and the liquid-cooled base 45 in vertical displacement.

[0031] Working principle: Before batch cooling of injection molded parts, the operator can connect the external coolant conduit to the first cooling pipe docking seat 1 and the second cooling pipe docking seat 44 respectively. Then, the operator can use the external loading module to batch import the processed injection molded parts into the shaping cavity 42. At this time, the liquid cooling base 45 is in the initial position, and the unloading guide seat 51 is completely in contact with the bottom of the sealing groove 41. After loading is completed, the servo motor 7 that drives the liquid cooling guide plate 2 is started. At this time, the servo motor 7 can synchronously drive the two sets of transmission screws 53 to rotate through the synchronous pulley 54 and the synchronous belt 55, so that the transmission screws 53 can drive the liquid cooling guide plate 2 to move down through the threaded sliding sleeve 9. The liquid cooling guide plate 2 can position the upper part of the injection molded part through the shaping upper mold 3. After the injection molded part is limited, the external coolant conduit can circulate the coolant into the liquid cooling guide plate 2 and the liquid cooling base 45 to cool the injection molded part in real time. At the same time, the rigid limitation of the upper mold 3 and the molded cavity 42 can also prevent the subsequent injection molded part from deforming. After cooling, the servo motor 7 driving the liquid cooling guide plate 2 can drive the liquid cooling guide plate 2 to lift and reset through the transmission screw 53. At the same time, another set of servo motors 7 driving the displacement of the liquid cooling base 45 is started. At this time, the servo motor 7 can drive the liquid cooling base 45 to move down through the threaded rotating sleeve 43. At the same time, the unloading guide 51 can automatically lift the cooled injection molded part until the injection molded part is completely separated from the molded cavity 42. Then the external unloading module can unload the injection molded part.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
