Description

Technical Field

[0001] The utility model relates to the technical field of plastic production, in particular to an injection molding device for plastic production. Background Art

[0002] The working principle of the injection molding machine is similar to that of a syringe used for injections. It uses the thrust of a screw or plunger to inject plasticized molten (i.e., viscous) plastic into a closed mold cavity, and obtains the product after solidification. Injection molding is a cyclic process, and each cycle mainly includes: quantitative feeding - melt plasticization - pressure injection - mold filling and cooling - mold opening and part removal. After the plastic part is taken out, the mold is closed again for the next cycle.

[0003] Conventional injection molding devices use a cylinder to drive the upper mold to operate, so that it can close or separate the mold with the lower mold, while the lower mold is a fixed structure. During maintenance and cleaning, it is inconvenient for operators to operate due to the limited space of the device structure.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an injection molding device for plastic production is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide an injection molding device for plastic production to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an injection molding device for plastic production, comprising an operating table and a transfer track, wherein the bottom of the operating table is connected to a base, the transfer track is mounted on one side of the operating table, and a lower mold group is slidably installed on the surface of the transfer track, and an upper mold group is mounted above the lower mold group, and an injection cylinder is symmetrically connected to the top of the upper mold group, and a device component is connected to the top of the injection cylinder, the transfer track comprises a guide rail, a support frame, a support pile and a buffer pile, a support frame is arranged at the bottom of one end of the guide rail, and one end of the guide rail is connected to a support pile, and a buffer pile is horizontally installed at the top of the support pile.

[0007] Furthermore, the operating table includes a processing table, a buffer column, a positioning hole and a limit block. The buffer column is installed on both the front and rear sides of the processing table, and the positioning hole is opened on the surface of the processing table, and a limit block is installed on one side of the surface of the processing table.

[0008] Furthermore, the buffer column is installed inside the processing table with an embedded structure, and the positioning holes are opened on the front and rear sides of the top surface of the processing table, and the limit block is set on the top surface of the positioning hole on one side.

[0009] Furthermore, the lower mold assembly includes a lower mold, positioning piles, limit piles, spring positioning rods and a sliding seat. The front side facade of the lower mold is symmetrically installed with positioning piles, and the rear side facade of the lower mold is symmetrically installed with limit piles. In addition, spring positioning rods are vertically installed in the middle of the front and rear sides of the lower mold, and sliding seats are installed at the front and rear ends of the bottom of the lower mold.

[0010] Furthermore, the bottom surface structure of the limiting pile matches the inner surface structure of the limiting block, and the sliding seat is slidably connected to the guide rail.

[0011] Furthermore, the upper mold assembly includes an upper mold, guide piles, shock-absorbing blocks and docking columns. Guide piles are installed on the left and right sides of the upper mold, and shock-absorbing blocks are provided on the front and back sides of the upper mold, and docking columns are vertically installed on the front and back sides of the bottom of the upper mold.

[0012] Furthermore, the device assembly includes a device main body, support columns and guide columns. The four diagonal parts of the device main body are vertically installed with support columns, and the left and right sides of the bottom of the device main body are vertically installed with guide columns.

[0013] Furthermore, the guide post slides through the middle of the guide post, and the docking post slides through the positioning post and the limit post at the same time and can be inserted into the interior of the positioning hole.

[0014] The utility model provides an injection molding device for plastic production, which has the following beneficial effects:

[0015] 1. The utility model installs a guide rail on the surface of the processing table, and at the same time extends the guide rail to the outside of one side of the entire operating table, and uses a support frame to provide structural support. In conjunction with a sliding seat installed at the bottom of the lower mold, the entire lower mold assembly can slide from the surface of the operating table to the migration track surface on the outside of one side. The cooperative use of the above-mentioned structure can make the entire lower mold assembly have sufficient structural flexibility, and the mobility of the structure can be used to facilitate operators to separate the lower mold assembly and the upper mold assembly for independent maintenance, and ensure the operable space between the device structures. The support piles and buffer piles arranged at one end of the guide rail can effectively prevent the moving lower mold assembly from rushing out of the guide rail surface, and play a good structural role in preventing buffering.

[0016] 2. The utility model sets a limit pile on the rear side of the lower mold, which cooperates with the buffer pile on the top side of the processing table, so that when the entire lower mold group moves back from the migration track surface to the operating table surface, it plays a limit blocking role and ensures that the entire lower mold group can stop directly below the upper mold group. At the same time, the spring positioning rod installed vertically in the center of the front and rear sides of the lower mold is used to insert its lower end into the positioning hole on the surface of the processing table by utilizing the elastic expansion of the structure, so that the entire lower mold group can be fixed to the surface of the operating table to avoid offset and affect the molding of the product during subsequent injection molding. The above structure does not affect the flexibility of the structure of the lower mold group itself, but also ensures sufficient structural stability for it.

[0017] 3. The utility model vertically installs docking columns on the front and rear sides of the bottom of the upper mold, and cooperates with the positioning holes on the surface of the processing table and the positioning piles on the front and rear sides of the lower mold. When the injection cylinder pushes the upper mold group toward the lower mold group below, the docking columns are vertically inserted into the positioning piles and the inside of the positioning holes in sequence, thereby ensuring the structural docking stability of the lower mold group and the upper mold group to the greatest extent. In cooperation with the operating table, the three can maintain sufficient docking firmness during the injection molding process to avoid interference and influence from external factors. In addition, the buffer column installed in the embedded structure and the inside of the processing table, in cooperation with the shock-absorbing block on the side of the upper mold, can effectively alleviate the impact force when the upper mold group and the lower mold group are docked, and prevent the injection cylinder from excessively pressing down to cause unnecessary structural damage. In addition, the structural resilience of the buffer column can assist the structural separation of the lower mold group and the upper mold group in the vertical direction to provide a good vertical upward thrust.

In conjunction with the sliding seat 405 installed at the bottom of the lower mold 401, the entire lower mold assembly 4 can slide from the surface of the operating table 1 to the surface of the migration track 3 on the outside of one side.

[0026] like Figures 1 to 5As shown, the operating table 1 includes a processing table 101, a buffer column 102, a positioning hole 103 and a limit block 104. The buffer columns 102 are installed on the front and rear sides of the processing table 101, and the surface of the processing table 101 is provided with a positioning hole 103, and the limit block 104 is installed on one side of the surface of the processing table 101.

The lower mold assembly 4 includes a lower mold 401, a positioning pile 402, a limit pile 403, a spring positioning rod 404 and a sliding seat 405.
