Description
Technical Field
[0001] The utility model relates to the technical field of collecting plastic parts, in particular to a material collecting device for an injection mold. Background Art
[0002] An injection mold can inject molten plastic into plastic parts. The structure of the injection mold is as Figures 1 to 2 shown. It includes a left half mold 1 and a right half mold 2. The left half mold 1 and the right half mold 2 are arranged opposite to each other left and right. An array of grooves 3 are formed on the right end face of the left half mold 1.
[0003] The method of using the injection mold to produce plastic parts is as follows:
[0004] S1. Drive the left half mold 1 and the right half mold 2 to close through a hydraulic cylinder. As Figure 3 shown, then inject molten plastic into the runner of the mold. The molten plastic enters each groove 3 through the runner. After waiting for a period of time, the required plastic parts can be injected in the grooves 3.
[0005] S2. Collecting the plastic parts: Workers place a paper box directly below the left half mold 1, and then drive the left half mold 1 and the right half mold 2 to separate through a hydraulic cylinder. During the separation process, the plastic parts are pushed out from the grooves 3, and the pushed plastic parts fall into the paper box, thus realizing the collection of a batch of plastic parts.
[0006] S3. Workers repeat the operations of steps S1 - S2 in this way, and a batch of plastic parts can be collected in the paper box.
[0007] However, in step S2, every time when collecting plastic parts, workers need to manually place a paper box directly below the left half mold 1, which undoubtedly increases the working intensity of workers.
[0008] In addition, there is a large height difference between the paper box and the left half mold 1. The plastic parts collide with each other during the falling process, resulting in serious scratches on the surface of the plastic parts, affecting the quality of the plastic parts. At the same time, the plastic parts impact the bottom of the paper box during the falling process, easily causing damage to the paper box, and new paper boxes need to be replaced again, which undoubtedly increases the production cost.
[0009] Therefore, there is an urgent need for a material collecting device that can improve the quality of plastic parts, greatly reduce the working intensity of workers, and reduce the production cost. Summary of the Utility Model
[0010] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a material collecting device for an injection mold that can improve the quality of plastic parts, greatly reduce the working intensity of workers, and reduce the production cost.
[0011] The object of the present utility model is achieved through the following technical solutions: A material receiving device for an injection mold, which includes a frame detachably connected to the bottom surface of the left half mold. The right end of the frame extends to the right of the left half mold. U-shaped grooves are respectively opened at the left ends of the front and rear sides of the frame. The frame is threaded to the bottom of the left half mold through locking screws penetrating the U-shaped grooves to fix the frame at the bottom of the left half mold.
[0012] On the bottom surface of the rear side of the frame, an inclined plate is fixedly provided and inclined forward. A buffer pad is fixedly provided on the inclined surface of the inclined plate along its length direction. The buffer pad is located directly below the right extension of the frame. On the inclined surface of the inclined plate, guard plates are also fixedly provided on the left and right sides of the buffer pad. A cylindrical cloth bag is sleeved on the lower end of the area surrounded by the inclined plate and the two guard plates, and the bottom of the cylindrical cloth bag is closed.
[0013] A plurality of connecting plates are fixedly connected between the two guard plates, and the two guard plates and the inclined plate are integrally formed.
[0014] The cylindrical cloth bag is a plastic cylindrical box.
[0015] The buffer pad is a PU soft leather pad.
[0016] On the upper and lower edges of the inclined plate, a plurality of threaded holes are respectively opened. On the upper and lower edges of the buffer pad, counterbore holes corresponding to the threaded holes are respectively opened. The buffer pad is threaded to the inclined plate through countersunk head screws penetrating the counterbore holes to fix the buffer pad on the inclined plate.

[0031] The following further describes the present utility model in conjunction with the accompanying drawings. The protection scope of the present utility model is not limited to the following:
[0032] As Figures 4 to 10 shown, a material receiving device for an injection mold includes a frame 4 detachably connected to the bottom surface of the left half mold 1. The right end of the frame 4 extends to the right of the left half mold 1. U-shaped grooves 5 are provided in the left ends of the front and rear sides of the frame 4. The frame 4 is threaded through the U-shaped grooves 5 by locking screws 6 and is threadedly connected to the bottom of the left half mold 1 to fix the frame 4 to the bottom of the left half mold 1. Since the frame 4 is detachably connected, the frame 4 can be installed on other models of molds, having the characteristic of high versatility.
[0033] A forwardly inclined inclined plate 7 is fixedly provided on the bottom surface of the rear side of the frame 4. A buffer pad 8 arranged along its length direction is fixedly provided on the inclined surface of the inclined plate 7. The buffer pad 8 is a PU soft leather pad. The buffer pad 8 is located directly below the right extension of the frame 4. Guard plates 9 located on the left and right sides of the buffer pad 8 are also fixedly provided on the inclined surface of the inclined plate 7. A cylindrical cloth bag 10 is sleeved on the lower end of the area surrounded by the inclined plate 7 and the two guard plates 9. The bottom of the cylindrical cloth bag 10 is closed. The cylindrical cloth bag 10 is a plastic cylindrical box.
[0034] A plurality of connecting plates 11 are fixedly connected between the two guard plates 9, and the two guard plates 9 and the inclined plate 7 are integrally formed. The function of the guard plate 9 is to prevent plastic parts from coming off the buffer pad 8.
[0035] A plurality of threaded holes 12 are formed in both the upper and lower edges of the inclined plate 7, and counterbore holes 13 corresponding to the threaded holes 12 are formed in both the upper and lower edges of the buffer pad 8. The buffer pad 8 is fixed to the inclined plate 7 by countersunk head screws passing through the counterbore holes 13 and being threadedly connected to the threaded holes 12.
[0036] The working process of the present utility model is as follows:
[0037] S1. The left half mold 1 and the right half mold 2 are driven to close by a hydraulic cylinder, and then molten plastic is injected into the runner of the mold. The molten plastic enters each groove 3 through the runner. After waiting for a period of time, the required plastic parts can be injection molded in the grooves 3.
[0038] S2. Collection of plastic parts: The left half mold 1 and the right half mold 2 are driven to separate by a hydraulic cylinder. During the separation process, the plastic parts are pushed out of the grooves. The pushed plastic parts pass through the frame 4, and then the plastic parts fall onto the buffer pad 8. Among them, the dropping direction of the plastic parts is as shown by the hollow arrow in Figure 4 ; then the plastic parts slide downward along the buffer pad 8, and finally the plastic parts fall into the tubular cloth bag 10, thereby realizing the collection of a batch of plastic parts.
[0039] S3. Workers repeat the operations of steps S1 - S2 in this way, and a batch of plastic parts can be collected in the tubular cloth bag 10.
[0040] In step S2, since the frame 4, the inclined plate 7, the buffer pad 8, and the tubular cloth bag 10 are all fixed to the left half mold 1, when the left half mold 1 and the right half mold 2 are separating, the frame 4, the inclined plate 7, the buffer pad 8, and the tubular cloth bag 10 also move synchronously with the left half mold 1. The tubular cloth bag 10 can always collect the plastic parts pushed out from the grooves 3, thereby realizing the automatic collection of plastic parts. It can be seen that compared with the method of workers using cardboard boxes to collect materials in the workshop, there is no need to manually place a cardboard box directly below the left half mold 1 for material collection, thus greatly reducing the working intensity of workers.
[0041] In addition, after the plastic parts falling from the frame 4 land on the buffer pad 8, they slide downward along the buffer pad 8 into the tubular cloth bag 10. The tubular cloth bag 10 plays a role in buffering the plastic parts, thereby reducing the sliding speed of the plastic parts, and further avoiding the surface damage of the plastic parts caused by mutual collision. Compared with the method of directly using a cardboard box to receive plastic parts, the quality of the plastic parts is improved. In addition, this material collection device replaces the use of cardboard boxes for material collection, eliminating the need to replace cardboard boxes, thus saving production costs.
[0042] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
