Description

Technical Field

[0001] The utility model belongs to the technical field of blow molding, in particular to a blow molding mold for processing plastic products. Background Art

[0002] Blow molding, also known as hollow blow molding, is a rapidly developing plastic processing method. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc. The resulting hollow containers are widely used as industrial packaging containers. According to the parison making method, blow molding can be divided into extrusion blow molding and injection blow molding. Newly developed ones include multi-layer blow molding and stretch blow molding. At the same time, their shapes are determined by corresponding molds.

[0003] In the process of blow molding, the raw materials need to be extruded and then wrapped by a mold for blow molding. In this process, the raw materials need to be cut manually. If the employees make mistakes in operation, they may be easily burned due to the high temperature. In addition, the mold is easily damaged after long-term use under high temperature. In addition, the traditional mold is not easy to replace, so it takes a certain amount of time to replace it, which affects the production efficiency. In order to solve the above problems, a blow molding mold for plastic product processing is urgently needed to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the problem that in the process of blow molding, the raw materials need to be extruded and then wrapped by a mold and then blow molded. In this process, the raw materials need to be cut manually. If the employees make mistakes in operation, they may be easily burned due to the high temperature. The mold is easily damaged after long-term use under the action of high temperature. The traditional mold is not easy to replace, so it takes a certain amount of time to replace it, which affects the production efficiency. A blow molding mold for plastic product processing is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a blow molding mold for processing plastic products, comprising a support seat, a first mounting block is fixedly connected to the top surface of the support seat, a replacement assembly is provided on one side of the first mounting block, a positioning column is fixedly connected to one side of the first mounting block, a second mounting block is provided on the top surface of the support seat, the positioning column is slidably connected to the second mounting block through a groove opened on one side of the second mounting block, a moving assembly is provided on one side of the second mounting block, and the support seat is fixedly connected to the air pipe through a through hole opened therein.

[0006] As a further description of the above technical solution:

[0007] The moving assembly comprises a fixed frame, one end of which is fixedly connected to a tool holder, and the tool holder is slidably connected to the first mounting block and the second mounting block through grooves provided at the top ends thereof.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0017] 1. In the utility model, a knife holder is arranged inside. When blow molding is performed, the raw material is extruded between the first mounting block and the second mounting block, and the push rod is started. The output end of the push rod drives the fixed frame to move and drives the second mounting block to move through the spring. At the same time, the fixed frame drives the knife holder to move and cuts the raw material through the knife holder. Through this design, it is achieved that the extruded raw material is cut off when the first mounting block and the second mounting block are closed, thereby eliminating manual labor and avoiding high temperature burns during manual operation, thereby reducing the occurrence of safety accidents and improving production efficiency.

[0018] 2. In the utility model, by arranging a mounting plate inside, when the mold needs to be replaced, the bidirectional threaded rod is rotated to move the mounting plates on both sides of the mold in opposite directions, thereby driving the fixed block to separate from the mold, taking out the old mold and replacing it with a new one. Through this design, the mold can be quickly replaced, so that the mold can be quickly replaced after being damaged, thereby reducing the time required for replacement and reducing its impact on production efficiency.

[0027] The moving assembly 7 includes a fixed frame 72, one end of which is fixedly connected to a knife holder 71, and the knife holder 71 is slidably connected to the first mounting block 1 and the second mounting block 6 through the grooves provided at the top ends thereof, the fixed frame 72 is slidably connected to the first mounting block 1 and the second mounting block 6 through the grooves provided at both ends thereof, the fixed frame 72 is slidably connected to the air pipe 5 through the groove provided at the bottom end thereof, one side of the fixed frame 72 is fixedly connected to a spring 73, the other end of the spring 73 is fixedly connected to the second mounting block 6, and the other side of the fixed frame 72 is fixedly connected to the output end of a push rod 74;

[0028] The specific implementation method is as follows: when blow molding is performed, the raw material is extruded between the first mounting block 1 and the second mounting block 6, and the push rod 74 is started. The output end of the push rod 74 drives the fixed frame 72 to move and drives the second mounting block 6 to move through the spring 73. At the same time, the fixed frame 72 drives the knife holder 71 to move. When it contacts the first mounting block 1, the fixed frame 72 drives the knife holder 71 to continue to move and compress the spring 73, so that the raw material is cut off by the knife holder 71, and at the same time, compressed air is blown into it through the air pipe 5 to expand it;

[0029] The replacement component 3 includes a bidirectional threaded rod 33, the threads at both ends of the bidirectional threaded rod 33 are opposite, both ends of the bidirectional threaded rod 33 are threadedly connected to a mounting plate 34, one side of the mounting plate 34 is fixedly connected to a fixing block 31, a mold 32 is slidably connected in the first mounting block 1, the mold 32 is slidably connected to the fixing block 31 through grooves opened on both sides thereof, the bidirectional threaded rod 33 is rotatably connected to the first mounting block 1 through a through hole opened in one side of the first mounting block 1, and the mounting plate 34 is slidably connected to the first mounting block 1 through a groove opened in the first mounting block 1.

[0030] The specific implementation method is as follows: when the mold 32 needs to be replaced, the bidirectional threaded rod 33 is rotated to move the mounting plates 34 on both sides of the mold 32 in opposite directions, thereby driving the fixed block 31 to separate from the mold 32, taking out the old mold 32 and replacing it with a new mold 32, and the bidirectional threaded rod 33 is rotated to drive the fixed block 31 to be reconnected with the mold 32 through the mounting plate 34.

[0031] Working principle: During blow molding, the raw material is extruded between the first mounting block 1 and the second mounting block 6, and the push rod 74 is started. The output end of the push rod 74 drives the fixed frame 72 to move and drives the second mounting block 6 to move through the spring 73. At the same time, the fixed frame 72 drives the knife holder 71 to move. When it contacts the first mounting block 1, the fixed frame 72 drives the knife holder 71 to continue to move, thereby cutting off the raw material through the knife holder 71, and at the same time, compressed air is blown into it through the air pipe 5 to expand it. When the mold 32 needs to be replaced, the two-way threaded rod 33 is rotated to make the mounting plates 34 on both sides of the mold 32 move in opposite directions, thereby driving the fixed block 31 to separate from the mold 32, taking out the old mold 32 and replacing it with a new mold 32.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
