Technical Field

[0001] The utility model relates to an injection molding machine for an automobile door lock outer shell, belonging to the technical field of injection molding machines. Background Art

[0002] An injection molding machine is a molding device used to produce plastic products. It heats the plastic and applies high pressure to it to fill the mold cavity and form a plastic product of the desired shape. Injection molding machines are widely used in industries such as home appliances, automobiles, aviation, instruments, national defense, telecommunications, medical care, construction and daily necessities. They are widely used because they can produce plastic products with complex shapes and structures.

[0003] During the operation of the existing injection molding machine, the staff needs to pour the raw materials from the barrel mouth, and then start the injection molding machine to inject the heated and melted raw materials into the mold to finally make the product. After the processing is completed, the product is pushed out by the push rod and enters the interior of the collection box by free fall. However, the existing molding equipment may be difficult to protect the products when collecting them. This method will cause the products to be damaged due to the impact during the falling process, thereby reducing the product qualification rate.

[0004] Therefore, a kind of automobile door lock outer shell injection molding machine is proposed. Utility Model Content

DETAILED DESCRIPTION

[0025] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0026] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1-5As shown, the embodiment of the utility model provides an injection molding machine for an automobile door lock shell, comprising a base 1, a feeding mechanism 2 and a positioning mechanism 3. The top of the base 1 is fixedly connected to the top of an operating table 4. Two feeding mechanisms 2 are arranged inside the operating table 4. The feeding mechanism 2 comprises a rotating shaft 201, a torsion spring 202 and a baffle 203. A collecting box 5 is arranged inside the base 1. A cavity 6 is provided on the front side of the base 1. The positioning mechanism 3 comprises a moving rod 301, an insert rod 302 and a tension spring 303. A working groove 7 is provided on the front side of the operating table 4. A protective door 8 is slidably connected to the front side of the operating table 4. The top of the operating table 4 is fixedly connected to the bottom of a feed port 9. The rotating shaft 201 is fixedly connected to the inside of the working groove 7. A torsion spring 202 is sleeved on the surface of the rotating shaft 201. A baffle 203 is fixedly connected to the surface of the torsion spring 202. A plurality of rubber pads 13 are arranged on the top of the baffle 203. The rubber pads 13 are evenly distributed on the top of the baffle 203.

[0029] The feeding mechanism 2 can reduce the falling buffer force of the automobile door lock shell when it is demoulded and fall, thereby preventing damage to the shell after demoulding. By setting the rubber pad 13, the falling force can be greatly reduced, thereby protecting the product and preventing damage.

[0030] Example 2

[0031] In one embodiment, the front side of the moving rod 301 passes through the front side of the cavity 6, the rear side of the moving rod 301 passes through the interior of the cavity 6, the bottom of the moving rod 301 is fixedly connected to the top of the insertion rod 302, the bottom of the insertion rod 302 is fixedly connected to the top of the tension spring 303, the bottom of the tension spring 303 is fixedly connected to the inner wall of the cavity 6, the tension spring 303 is sleeved on the surface of the insertion rod 302, the bottom of the insertion rod 302 passes through the interior of the collection box 5, the top of the collection box 5 is provided with a fixing groove 10, the insertion rod 302 is in close contact when plugged in, the interior of the cavity 6 is provided with a limiting groove 11, the rear side of the insertion rod 302 is slidably connected to the interior of the limiting groove 11 through a sliding rod 12, the top of the base 1 is fixedly connected to a fixing seat 14, and the bottom of the fixing seat 14 is fixedly connected to a protective pad 15.

[0032] The collection box can be fixed by the positioning mechanism 3 so that it can be fixed in an embedded manner, which makes it easier to collect the product while reducing the operating area. By providing a fixing seat 14 and a protective pad 15, the device can be stably fixed when placed, thereby improving its stability during placement.

[0033] When the utility model is working, firstly, the injection molding raw material is poured into the inside of the discharge port 9, the injection molding machine is started, and the raw material is melted by internal heating before injection molding. After completion, it is demoulded. The demoulded product falls vertically due to gravity. The rubber pad 13 on the top of the baffle 203 buffers its falling force. Then, the baffle 203 is opened by the rotation of the torsion spring 202 and the rotating shaft 201, so that the product falls into the inside of the collection box. The torsion spring 202 quickly resets the baffle 203 after opening. The next product is buffered for protection. When the collection box is collected, the moving rod 301 is pulled upward. The moving rod 301 drives the insertion rod 302 to move upward. The insertion rod 302 moves upward according to the movement trajectory provided by the restriction while stretching the tension spring 303, so that the insertion rod 302 moves to the inside of the cavity 6. At this time, the collection box can be pulled forward to clean the products inside it. After completion, the collection box can be reinserted, the moving rod 301 is released, and the insertion rod 302 is reinserted into the inside of the fixed groove 10 through the return force of the tension spring 303.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
