Abstract

The invention relates to a structure for producing a toothbrush welding head piece, and in particular to a pneumatically assisted micro-gram weight product demoulding structure, so as to solve the technical problem that if the adsorbed product is not separated from the mold in time, the mold will be crushed after the mold is closed again. The structure comprises a push plate, a first slide column, a second slide column, a pneumatically assisted micro-gram weight product demoulding structure group, an air pipe structure, a connecting frame, a first mounting connecting plate, and a second mounting connecting plate. The connecting frame is fixedly provided with the second mounting connecting plate, the first mounting connecting plate is fixedly provided with the first slide column, and the first slide column and the second slide column are fixedly provided with the first mounting connecting plate. After the mold is opened, the mold pushes the plate to eject the product. After the push plate is ejected, an injection molding machine performs a blowing action. High-pressure gas enters the pneumatic plate through a hose and an air nozzle A. The trumpet-shaped outlet of the pneumatic plate is trumpet-shaped, so that the gas will be dispersed after leaving the pneumatic plate.

Description

Technical Field

[0001] The invention relates to a structure for producing a toothbrush welding head piece, in particular to a pneumatically assisted micro-gram weight product demoulding structure. Background Art

[0002] With the use of ultrasonic welding technology for toothbrushes, we need to produce toothbrush heads for hair transplantation, and then connect the heads to the toothbrush handles through ultrasonic welding technology. In the process of producing heads, since the weight of the heads is very small, about 0.1-0.2 grams, if static electricity is generated on the product, it will often be adsorbed on the mold after the mold push plate is ejected. If the adsorbed product is not separated from the mold in time, the mold will be crushed after the mold is closed again. Summary of the invention

[0003] The purpose of the present invention is to provide a pneumatically assisted micro-weight product demoulding structure to solve the technical problem that if the adsorbed product is not separated from the mold in time, the mold will be crushed after the mold is closed again.

[0004] To achieve the above purpose, the specific technical solution of a pneumatically assisted micro-weight product demoulding structure of the present invention is as follows:

[0005] A pneumatically assisted micro-gram-weight product demoulding structure comprises a push plate, a first slide column, a second slide column, a pneumatically assisted micro-gram-weight product demoulding structure group, an air pipe structure, a connecting frame, a first mounting connecting plate, and a second mounting connecting plate. The connecting frame is fixedly mounted with the second mounting connecting plate, the first mounting connecting plate is fixedly mounted with the second mounting connecting plate, the first mounting connecting plate is fixedly mounted with the first slide column and the second slide column, the push plate is slidably connected with the first slide column and the second slide column at the same time, the push plate is mounted with the pneumatically assisted micro-gram-weight product demoulding structure group, and the air pipe structure is mounted on the pneumatically assisted micro-gram-weight product demoulding structure group.

[0006] Furthermore, a mold end rod is fixedly mounted on the mounting connection plate, a product part cavity is opened on the push plate, the product part cavity is slidably connected to the mold end rod, and a product part is arranged in the product part cavity.

[0007] Furthermore, an air nozzle A is installed on the air pipe structure.

[0008] Furthermore, the pneumatically assisted micro-gram weight product demoulding structure group includes a pneumatic plate, an air nozzle mounting port, a trumpet-shaped outlet, a sliding closing plate, a gas chamber, a sliding cavity, a rod sliding cavity, a positioning slot, a positioning rod, and a positioning rod push spring. The pneumatic plate is provided with an air nozzle mounting port, and an air nozzle A is installed in the air nozzle mounting port. The pneumatic plate is provided with a trumpet-shaped outlet, and a gas chamber is provided in the pneumatic plate, and the gas chamber is connected to the air nozzle mounting port. The trumpet-shaped outlet is provided with a sliding cavity, and a sliding closing plate is slidably installed in the sliding cavity. The sliding closing plate is provided with a rod sliding cavity, and a positioning rod is slidably installed in the rod sliding cavity. There are two positioning rods, and a positioning rod push spring is provided between the two positioning rods. A positioning slot is provided in the sliding cavity, and the positioning slot is cooperatively connected with the positioning rod.

[0009] Furthermore, the positioning slots are provided in plurality, and the plurality of positioning slots are arranged in a linear array along the sliding cavity.

[0010] Furthermore, the trumpet-shaped outlets are provided in plurality, and the trumpet-shaped outlets are arranged in a linear array along the pneumatic plate.

[0011] Furthermore, the gas chamber is communicated with a trumpet-shaped outlet.

[0012] Furthermore, an auxiliary rod is fixedly mounted on the sliding closing plate.

[0013] The advantages of the present invention are:

[0014] After the mold is opened, the push plate ejects the product. After the push plate is ejected, the injection molding machine performs the blowing action. The high-pressure gas enters the pneumatic plate through the hose and the air nozzle A. The trumpet-shaped outlet of the pneumatic plate is trumpet-shaped, so the gas will diverge after leaving the pneumatic plate; after the divergent high-speed gas diffuses to the push plate surface of the mold, it will contact the product parts and give them a thrust. Under the thrust of the gas, the product parts adsorbed on the push plate will naturally fall down. This ensures that all products can fall after the mold is ejected, solves the problem of demolding of micro-gram products, improves the production efficiency of the product, and eliminates the phenomenon of mold compression; at the same time, the sliding closing plate slides along the sliding cavity, so that the opening area formed by the sliding closing plate and the trumpet-shaped outlet changes, so as to adjust the ventilation volume flowing out through the trumpet-shaped outlet and adjust the demolding effect of the product parts.
