This utility model relates to the field of feeding platforms and discloses a feeding platform for quick replacement of injection molding machine barrels. The feeding platform includes a notch that allows the barrel to pass through when it is vertically raised or lowered. When the barrel is vertically raised or lowered, the notch allows the barrel to pass through without interfering with it. Therefore, the barrel can be replaced without removing the feeding platform, reducing replacement and maintenance time and realizing quick barrel replacement.

Description

Technical Field

[0001] This utility model relates to the field of feeding platforms, and more particularly to a feeding platform for quick barrel replacement in injection molding machines. Background Technology

[0002] The injection molding machine is equipped with a feeding platform 1, on which a hopper is mounted. A feeding pipe, communicating with the barrel 6, is located at the bottom of the hopper. A through-slot 4 is provided on the feeding platform 1 for the feeding pipe to pass through. The feeding platform 1 is a platform designed for workers to stand and add raw materials. Typically, the feeding platform 1 is fixedly mounted on the injection molding machine and positioned above the barrel 6. The feeding platform 1 is surrounded by protective railings 5. (See details...) Figure 1 .

[0003] However, when the injection molding machine barrel 6 needs to be replaced or repaired, after the barrel 6 has been ejected to the bottom, the feeding platform 1 is fixed above the barrel 6, blocking the space for vertical lifting of the barrel 6. Therefore, the feeding platform 1 needs to be removed before the barrel 6 can be removed for replacement or repair, which increases the time for replacement and repair. Utility Model Content

[0004] This invention addresses the drawback of existing technologies that require the removal of the feeding platform before barrel replacement, which increases replacement and maintenance time. It provides a feeding platform for quick barrel replacement in injection molding machines.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] A feeding platform for quick barrel change of an injection molding machine includes a feeding platform with a notch for the barrel to pass through when the barrel is vertically raised or lowered.

[0007] With the above solution, when the barrel is raised and lowered vertically, the notch allows the barrel to pass through without interfering with it. Therefore, the barrel can be replaced without removing the feeding platform, reducing replacement and maintenance time and enabling rapid barrel replacement.

[0008] Preferably, a protective structure can be detachably installed at the notch to prevent raw materials from falling onto the injection molding machine during the feeding process.

[0009] Preferably, the protective structure includes a baffle that is detachably installed at the notch to expose or cover it, and a through groove through the baffle for the feeding pipe to pass through.

[0010] The above solution is designed to prevent raw materials from falling directly onto the injection molding machine through the notch during the feeding process, and the through groove is for the feeding pipe to pass through.

[0011] As a preferred option, the feeding platform and the circumferential opening are equipped with protective railings.

[0012] Using the above solution, the guardrail is used to protect workers loading materials on the feeding platform and prevent them from falling accidentally.

[0013] Preferably, at least one of the guardrails on both sides of the gap has a clearance distance between it and the gap to reduce interference between the hopper and the guardrail.

[0014] With the above solution, since the feed pipe is located on the baffle and the hopper is also located above the baffle, the size or model of the hopper varies on different injection molding machines. Some injection molding machines in Europe also have the function of horizontally moving the hopper. Therefore, setting the clearance distance is to avoid the guardrails on both sides of the gap from interfering with the installation or movement of the hopper.

[0015] This utility model has significant technical effects due to the adoption of the above technical solutions: when the barrel is raised and lowered vertically, the notch allows the barrel to pass through without interfering with it, so the barrel can be replaced without removing the feeding platform, reducing replacement and maintenance time and realizing rapid barrel replacement.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0022] Example

[0023] A feeding platform for quick barrel change in injection molding machines, as described in the following reference. Figures 2 to 4 It includes a feeding platform 1, which has a notch 2. When the barrel 6 is raised and lowered vertically, the notch 2 allows the barrel 6 to pass through without interfering with it.

[0024] A baffle 3 is detachably installed at the notch 2, which can be exposed or covered. The detachable connection between the baffle 3 and the notch 2 is existing technology, commonly using bolt fixing, and therefore is not shown in the figure and will not be described in detail here. A through groove 4 is provided on the baffle 3 for the feeding pipe to pass through.

[0025] Both the feeding platform 1 and the notch 2 are equipped with guardrails 5 around their perimeter. At least one of the guardrails 5 on both sides of the notch 2 has a clearance distance between it and the notch 2 to reduce interference between the hopper and the guardrail.

[0026] During normal use, the baffle 3 is installed at the notch 2 to prevent raw materials from falling onto the injection molding machine during feeding. When the barrel 6 needs to be replaced, only the baffle 3 needs to be removed to expose the notch 2. The entire feeding platform 1 does not need to be removed to replace the barrel 6, reducing replacement and maintenance time and enabling quick replacement of the barrel 6.

[0027] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
