Description

Technical Field

[0001] The present application relates to the technical field of injection molding equipment, and in particular to a material receiving mechanism and injection molding equipment. Background Art

[0002] After the injection molding is completed, the fixed mold plate and the movable mold plate are opened separately, and the materials can be collected by a robot, but the cost of this material collection method is relatively high. The cost of manual material collection is lower, but there are certain operational risks, and the material collection efficiency is low.

[0003] In this regard, China's patent application number CN202223428161.X discloses an automatic material receiving injection molding machine. In this scheme, a material receiving device is arranged below the main receiving port. The injection molded product is demoulded under the drive of the ejector pin, first contacts with the blanking plate, and falls onto the conveyor belt under the inclination of the blanking plate. The injection molded product is transported by the conveyor belt. During the transportation process, the appearance of the injection molded product is preliminarily inspected by the appearance detector, and the feedback is fed back to the workers for screening.

[0004] However, in the process of implementing the technical solutions in the embodiments of the present application, the inventors of the present application found that the above technology has at least the following technical problems:

[0005] 1. The posture of the finished product falling on the blanking plate after demoulding is uncertain, and the subsequent sequence still needs to be re-stacking, which increases working hours and reduces efficiency;

[0006] 2. The finished product is on the conveyor belt, and the camera can only detect the front of the finished product, but not the back. Utility Model Content

[0007] In order to make up for the above deficiencies, the present application provides a material receiving mechanism and an injection molding device, aiming to improve the problems mentioned in the above background technology.

[0008] In the first aspect, an embodiment of the present application provides a material receiving mechanism, comprising an injection molding machine and a moving part, wherein the injection molding machine is provided with a mold, a finished product is injection-molded in the mold, a bracket is provided on the moving part, a support rod is elastically hinged on the bracket, the support rod is movably embedded in the mold, the finished product falls on the support rod, a camshaft is rotatably connected to the bracket, a motor is connected to the upper shaft of the camshaft, the camshaft drives the support rod to deflect, two upper and lower detection probes are provided on the injection molding machine, a transfer mechanism is provided next to the injection molding machine, and the moving part moves between the mold and the transfer mechanism.

[0009] In a specific embodiment, the lower end of the support rod is chamfered.

[0010] In the above implementation process, when the drag rod falls onto the mold, the bevel is used to help guide and position it, ensuring that the support rod is accurately embedded in the mold.

[0011] In a specific embodiment, the bracket includes an L-shaped frame and a support plate, and two support plates are fixedly connected to the L-shaped frame. The two support plates are respectively located on both sides of the mold, and each support plate is provided with two support rods and one camshaft.

[0012] In the above implementation process, the L-shaped frame and the two support plates form a door-shaped structure, which can be extended into the injection molding machine, with little modification to the injection molding machine, thereby reducing the improvement cost. In this embodiment, a coil spring is provided on the hinge shaft of the support rod to realize elastic hinge, and the support plate forms a unidirectional limit for the support rod, so that the support rod can maintain a horizontal supporting state, and can also be tilted inward under the manipulation of the camshaft to release the finished product.

[0013] In a specific embodiment, a counterweight block is also provided on the L-shaped frame.

[0014] In the above implementation process, since the L-shaped frame and the two support plates as well as the camshaft and the motor thereon need to extend into the injection molding machine, the moving parts can only be located at one corner for support, so a counterweight is used to maintain balance.

[0015] In a specific embodiment, the moving member includes a slide rail and a slider, the slider is slidably connected to the slide rail, and a lead screw is threaded on the slider.

[0016] In a specific implementation manner, an electric lifting rod is fixedly connected to the sliding block, and the upper end of the lifting rod is fixedly connected to the L-shaped frame.

[0017] In the above implementation process, the screw rod rotates to drive the slider to move linearly, and the lifting rod is used to control the vertical height of the bracket, so that the finished product is taken out of the mold and moved to the top of the transfer mechanism.

[0018] In a specific embodiment, the transport mechanism is a conveyor belt.

[0019] In the above implementation process, the conveyor belt moves the stacked finished products to the subsequent order for packaging.

[0020] In a second aspect, the present application further provides an injection molding device, comprising the above-mentioned material receiving mechanism.

[0021] Compared with the prior art, the beneficial effects of the present application are: a drag rod is embedded in the mold, the finished product is directly lifted out after the mold is opened, and is stacked on the transfer mechanism after visual inspection by the upper and lower detection probes, ensuring that both the front and back sides of the finished product are detected, and the motor is used to drive the camshaft to tilt the support rod, thereby releasing the finished product onto the transfer mechanism, improving the stability of the finished product receiving posture, and directly stacking it, thereby improving efficiency.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0029] See also Figure 1-Figure 4The present application provides a material receiving mechanism, including an injection molding machine 10 and a moving part 40. The injection molding machine 10 is provided with a mold 20, and a finished product 30 is injection-molded in the mold 20. The moving part 40 is provided with a bracket 50, and a support rod 60 is elastically hinged on the bracket 50. The support rod 60 is movably embedded in the mold 20, and the finished product 30 falls on the support rod 60. A camshaft 70 is rotatably connected to the bracket 50, and a motor 80 is connected to the camshaft 70. The camshaft 70 drives the support rod 60 to deflect. Two upper and lower detection probes 90 are provided on the injection molding machine 10. A transfer mechanism 100 is provided next to the injection molding machine 10, and the moving part 40 moves between the mold 20 and the transfer mechanism 100. Among them, a drag rod is embedded in the mold 20, and the finished product 30 is directly lifted out after the mold is opened, and is stacked on the transfer mechanism 100 after visual inspection by the upper and lower detection probes 90, ensuring that both the front and back sides of the finished product 30 are detected. The motor 80 drives the camshaft 70 to tilt the support rod 60, thereby releasing the finished product 30 onto the transfer mechanism 100, improving the stability of the material receiving posture of the finished product 30, and directly stacking it, thereby improving efficiency.

[0030] See also Figure 1-Figure 4 The lower end of the support rod 60 is provided with a chamfered angle. When the drag rod falls onto the mold 20, the chamfered angle is used to help guide and position the drag rod, so as to ensure that the support rod 60 is accurately embedded in the mold 20.

[0031] See also Figure 1-Figure 4 The bracket 50 includes an L-shaped frame 51 and a support plate 52. Two support plates 52 are fixedly connected to the L-shaped frame 51. The two support plates 52 are respectively located on both sides of the mold 20. Two support rods 60 and a cam shaft 70 are arranged on each support plate 52. The L-shaped frame 51 and the two support plates 52 form a door-shaped structure, which can be extended into the injection molding machine, and the modification of the injection molding machine is small, thereby reducing the improvement cost. In this embodiment, a coil spring is arranged on the hinge shaft of the support rod 60 to realize elastic hinge, and the support plate 52 forms a unidirectional limit for the support rod 60, so that the support rod 60 can maintain a horizontal lifting state, and can also be tilted inward under the toggle of the cam shaft 70, thereby releasing the finished product 30.

[0032] See also Figure 1-Figure 4 , a counterweight 53 is also provided on the L-shaped frame 51. Since the L-shaped frame 51 and the two support plates 52 as well as the camshaft 70 and the motor 80 thereon need to extend into the injection molding machine, the moving part 40 can only be located at one corner for support, and therefore the counterweight 53 is utilized to maintain balance.

[0033] See also Figure 1-Figure 4The moving member 40 includes a slide rail 41 and a slider 42. The slider 42 is slidably connected to the slide rail 41, and a screw is screwed to the slider 42. An electric lifting rod 43 is fixedly connected to the slider 42, and the upper end of the lifting rod 43 is fixedly connected to the L-shaped frame 51. The screw rotates to drive the slider 42 to move linearly, and the lifting rod 43 is used to control the vertical height of the bracket 50, so that the finished product 30 is taken out of the mold 20 and moved to the top of the transfer mechanism 100.

[0034] See also Figure 1-Figure 4 The transfer mechanism 100 is a conveyor belt. The conveyor belt moves the stacked finished products 30 to the subsequent order for packaging.

[0035] See also Figure 1-Figure 4 The present application further provides an injection molding device, including the above-mentioned material receiving mechanism.

[0036] The working principle of the material receiving mechanism is as follows: the support rod 60 is embedded in the mold 20 and forms an integral body with the mold 20. When the injection molding of the finished product 30 is completed, the mold 20 is opened, and the lifting rod 43 is raised, so that the support rod 60 is separated from the mold 20 and the finished product 30 is lifted out. Then the screw rod rotates to drive the slider 42 to move linearly and move the finished product 30 outward. During the movement, it passes through the visual inspection of the upper and lower detection probes 90, and then reaches the conveyor belt. The lifting part drops to a suitable height, and then the motor 80 drives the camshaft 70 to rotate at high speed for one circle. The camshaft 70 drives the four support rods 60 to deflect quickly. Since the deflection speed is very fast, the synchronization is very high, and the falling distance of the finished product 30 is not high, The finished products 30 can accurately fall onto the conveyor belt below and be stacked up one by one. Then, the support rod 60 will return to its original state under the action of elasticity. When encountering unqualified products, the moving part 40 will move to the outer area of ​​the conveyor belt and then put it down. In summary, the drag rod is embedded in the mold 20, and the finished products 30 are directly lifted out after the mold is opened, and are stacked on the transfer mechanism 100 after visual inspection by the upper and lower detection probes 90, ensuring that the front and back sides of the finished products 30 are detected. The motor 80 is used to drive the camshaft 70 to tilt the support rod 60, thereby releasing the finished products 30 onto the transfer mechanism 100, thereby improving the stability of the material receiving posture of the finished products 30, and directly stacking them, thereby improving efficiency.
