Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts molding, in particular to an injection molding mold for automobile injection molding parts. Background Art

[0002] A car is made up of many parts, and plastic parts are one of its important components. The most common method for manufacturing plastic parts is injection molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of patterns and colors, shapes from simple to complex, sizes from large to small, and precise product dimensions. The product is easy to update and can produce parts with complex shapes.

[0003] A lot of plastic parts are needed in the production of automobiles. Each plastic part has its own exclusive mold for manufacturing. It is not possible to manufacture a production line for a single mold. Therefore, the mold needs to be replaced on the production line. Traditional molds are generally fixed on the production line with multiple bolts. Currently, before fixing, it is necessary to assist in positioning the position of the holes between the mold and the template. When the position is not aligned, it is easy to cause thread slippage, affecting subsequent installation and removal operations; second, the force on the four corners is uneven, resulting in poor molding quality during subsequent injection molding. How to achieve alignment between the positioning mold and the template before installation is a problem that needs to be solved now. Utility Model Content

[0006] In a preferred embodiment, the laser alignment assembly includes a laser receiver and a laser transmitter, and the laser receiver and the laser transmitter are detachably mounted on the side walls of the lower mold and the upper mold, respectively.

[0007] In a preferred embodiment, the upper die and the lower die are fixed to the upper mounting seat and the lower mounting seat respectively by fastening bolts.

[0008] In a preferred embodiment, a liquid inlet connected to the upper mold is fixed on the upper mounting seat by screws, and a filter screen is fixed in the liquid inlet by screws.

[0009] In a preferred embodiment, the laser receiver and the laser emitter are on the same vertical line.

[0010] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0011] 1. In the present utility model, positioning insertion rods are reserved on the upper mounting seat and the lower mounting seat, and positioning slots are correspondingly designed in the upper die and the lower die. When installing the upper die and the lower die, the cooperation of the positioning insertion rods and the positioning slots can be used to assist in defining the installation positions of the upper die and the lower die, thereby ensuring the accuracy of subsequent installation.

[0012] 2. In the present utility model, during each mold closing, the laser alignment assembly can be used to assist in checking whether the positions of the upper and lower dies are offset. When an offset occurs, the staff can be reminded in time to perform maintenance operations to avoid collisions between the molds and cause safety accidents. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0017] Refer to Figure 1-2 , an injection molding die for automotive injection molded parts, including an upper die 10 and a lower die 5 arranged oppositely up and down. On the opposite sides of the upper die 10 and the lower die 5, there are respectively an upper mounting seat 1 and a lower mounting seat 9. On both sides of the opposite ends of the upper mounting seat 1 and the lower mounting seat 9, positioning insertion rods 11 protrude. On both sides of the opposite ends of the upper die 10 and the lower die 5, positioning slots 6 are correspondingly opened for the positioning insertion rods 11. Positioning insertion rods 11 are reserved on the upper mounting seat 1 and the lower mounting seat 9, and positioning slots 6 are correspondingly designed in the upper die 10 and the lower die 5. When installing the upper die 10 and the lower die 5, the cooperation of the positioning insertion rods 11 and the positioning slots 6 can be used to assist in defining the installation positions of the upper die 10 and the lower die 5, thereby ensuring the accuracy of subsequent installation.

[0018] Wherein, a hydraulic lifting system is further provided above the upper mold 10 for realizing the lifting of the upper mold 10 to complete the corresponding mold opening or closing operation.

[0019] Furthermore, a laser alignment component (electrically connected to the control end of the mold) is provided between the lower mold 5 and the upper mold 10 for realizing the precise positioning of the lower mold 5 and the upper mold 10. The laser alignment component includes a laser receiver 7 and a laser transmitter 8. The laser receiver 7 and the laser transmitter 8 are respectively detachably mounted on the side walls of the lower mold 5 and the upper mold 10. The laser receiver 7 and the laser transmitter 8 are on the same vertical straight line. A laser alignment component is designed corresponding to between the upper and lower molds. During each mold closing, the laser receiver 7 and the laser transmitter 8 can be used to assist in checking whether the positions of the upper and lower molds are offset. When there is an offset, there will be a deviation between the laser receiver 7 and the laser transmitter 8, and at this time, the emitted laser cannot be received, and then the signal can be transmitted to the control end of the mold (not shown in the figure) in time to timely remind the staff to perform maintenance operations to avoid collisions between the molds before and cause safety accidents.

[0020] Furthermore, the upper mold 10 and the lower mold 5 are respectively fixed to the upper mounting seat 1 and the lower mounting seat 9 through fastening bolts 4. When it is necessary to disassemble the upper mold 10 and the lower mold 5, loosening the fastening bolts 4 can take out the upper mold 10 and the lower mold 5 from the mold.

[0021] Furthermore, a liquid inlet 3 communicating with the upper mold 10 is fixed to the upper mounting seat 1 through screws. A filter screen 2 is fixed in the liquid inlet 3 through screws. The filter screen 2 can be used to filter the discharged molding liquid. One is to cut off air bubbles, and the other is to filter out the molding liquid that is not completely melted, so as to ensure the subsequent molding quality.

[0022] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
