Description

Technical Field

[0001] This utility model relates to the field of injection mold ejection, and in particular to an injection mold ejection structure. Background Technology

[0002] Injection molds are specialized tools used in plastic injection molding processes. They are mainly used to manufacture plastic products of various shapes and sizes. Injection molds typically perform ejection operations, which involves the use of ejection structures.

[0003] Application No. 202321563256.4 mentions an injection mold for convenient material discharge, including a base plate, a hydraulic rod, a reset plate, and a toggle mechanism. The base plate has a discharge port, a housing is fixedly installed at the bottom of the base plate, a vertical plate is fixedly installed at the top of the base plate, a transverse plate is provided on one side of the vertical plate, a cavity is provided on the vertical plate, a punch is provided on the transverse plate, a housing is fixedly installed on the other side of the vertical plate, and an opening is provided on the vertical plate. The hydraulic rod is located at the top of the base plate, and the free end of the hydraulic rod is fixedly connected to the transverse plate. The reset plate is located on the vertical plate, and a toggle block is fixedly installed on the other side of the reset plate. The toggle block is located in the opening, and the toggle mechanism is located on the housing. The toggle mechanism can drive the cavity to vibrate left and right.

[0004] The discharge structure includes a discharge port, a tossing mechanism, and a housing. The tossing mechanism is installed on the injection mold, causing the mold to vibrate and discharge the molded product. The molded product falls into the discharge port and then enters the housing for collection. After a certain number of molded products are collected in the housing, they are removed. When the housing is discharging and collecting the molded products, workers usually need to check the inside of the housing from time to time to prevent it from being too full. However, this method increases the labor intensity of the workers. Therefore, it is necessary for the housing to provide reminders for the collection of molded products. Utility Model Content

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] This utility model provides, for example Figure 1-4 The diagram shows a material ejection structure for an injection mold.

[0041] Example 1

[0042] The injection mold body 1 includes a base plate 2 fixedly connected to the bottom, which is beneficial for supporting the injection mold body 1. The top of the base plate 2 has a discharge port 5, which is beneficial for the injection molded product to fall into the weighing frame 41 through its interior. The injection mold body 1 is consistent with the existing technology and will not be described in detail here.

[0043] The housing 3 is fixedly connected to the bottom of the base plate 2, which facilitates the installation of the symmetrical weight frame 41;

[0044] Weighing mechanism 4 is located inside box 3. Weighing mechanism 4 is used to weigh injection molded products and reminds customers to take them out when the weight reaches the set weight.

[0045] Furthermore, the weighing mechanism 4 includes a weighing frame 41 disposed inside the housing 3. The weighing frame 41 facilitates the collection of injection-molded finished products. An electronic scale 42 is installed at the bottom of the housing 3. The electronic scale 42 facilitates the weighing of the weighing frame 41, ensuring that the injection-molded finished products contained in the weighing frame 41 reach a certain weight. An alarm 43 is then triggered via an electrical signal, prompting the weighing frame 41 to be removed. The weighing weight can be set to tare. The electronic scale 42 is used to weigh the symmetrical weighing frame 41. The bottom of the electronic scale 42 is symmetrically equipped with sliding parts, which facilitates the sliding installation of the electronic scale 42 and provides auxiliary guidance to increase the stability of the electronic scale 42 in use. The bottom of the inner wall of the housing 3 is symmetrically provided with sliding grooves that are adapted to the sliding parts. The alarm 43 is installed on the top of the base plate 2 and is electrically connected to the electronic scale 42. The alarm 43 transmits signals to the electronic scale 42 through electrical signals.

[0046] Furthermore, the weighing mechanism 4 also includes an auxiliary wheel 44, a support base 45, a positioning component, and an assembly component. The auxiliary wheel 44 facilitates the movement of the weighing frame 41 on the electronic scale 42, making it easy to slide and remove the weighing frame 41 for convenient operation. The support base 45 facilitates the rolling of the auxiliary wheel 44 within it, providing guidance and positioning for the installation of the weighing frame 41. The auxiliary wheel 44 is fixedly connected to the bottom of the weighing frame 41, and the support base 45 is fixedly connected to the top of the electronic scale 42. The auxiliary wheel 44 is located inside the support base 45. The positioning component is located at the bottom of the weighing frame 41 and is used to position the weighing frame 41 during installation. The assembly component is located on the side of the electronic scale 42 and is used to connect and fix the electronic scale 42.

[0047] Specifically, the positioning components include a fixing plate 46, a positioning frame 48, and a second magnet 49. The fixing plate 46 supports the first magnet 47, and the positioning frame 48 is L-shaped, which supports the second magnet 49. The second magnet 49 and the first magnet 47 magnetically fix the positioning frame 48 and the fixing plate 46, which in turn magnetically fixes the weighing frame 41, preventing the weighing frame 41 from sliding arbitrarily. The fixing plate 46 is fixedly connected to the top of the electronic scale 42, and the first magnet 47 is fixedly connected to the side of the fixing plate 46. The positioning frame 48 is fixedly connected to the bottom of the weighing frame 41, and the second magnet 49 is embedded in the side of the positioning frame 48. The opposite magnetic poles of the second magnet 49 and the first magnet 47 are opposite to each other.

The movable frame 410 facilitates support for the electronic scale 42. The fixed frame 411 facilitates the sliding of the limiting frame 412 within it, providing sliding support for the limiting frame 412. The limiting frame 412 is L-shaped, which helps to define the relative positions of the fixed frame 411 and the movable frame 410, thereby facilitating the installation and disassembly of the electronic scale 42. The sliding plate 415 facilitates the movement of the limiting frame 412, enabling driving operations to disengage the limiting frame 412 from the movable frame 410. The threaded post 413 facilitates the movement of the sliding plate 415 with... The locking ring 414 is connected to the threaded post 413 to lock and fix the sliding plate 415, which in turn helps to lock and fix the limiting frame 412, preventing the limiting frame 412 from sliding freely. The moving frame 410 is fixedly connected to the side of the electronic scale 42, and the fixed frame 411 is fixedly connected to the bottom of the inner wall of the box 3. The limiting frame 412 slides through the inside of the fixed frame 411, and the end of the limiting frame 412 slides through the inner cavity of the moving frame 410. The sliding plate 415 is fixedly connected to the top of the limiting frame 412. A through groove is opened on the side of the sliding plate 415. The threaded post 413 slides through the inner cavity of the through groove, and the end of the threaded post 413 is connected to the top of the fixed frame 411. The locking ring 414 is threaded through the outside of the threaded post 413.
