Description

Technical Field

[0001] The invention relates to the field of insert injection molds, and in particular to an automobile battery component insert product injection mold and a method. Background Art

[0002] Circuit board brackets for new energy vehicle battery pack accessories are mainly used to fix automobile circuit boards and batteries. The products must meet the durability test and collision test of the automobile, so the strength, durability, flame retardancy and other related parameters of the product itself are relatively strict. At the same time, considering the prevention of conductivity and leakage of the product, the injection molding material uses nylon plus 40% glass fiber to improve the durability, assembly strength and other related properties of the product. In terms of installation strength, metal inserts will be embedded in the connection with the car body through the insert injection molding technology during the injection molding process to meet the product assembly size, position accuracy, tensile strength and other product requirements.

[0003] Therefore, it is necessary to install the insert and perform injection molding to wrap the nylon plus 40% glass fiber on the circuit board bracket, that is, on the metal plate.

[0004] For insert injection molds, the error in the size of the insert itself directly affects the quality of the injection molded product. When installing the insert, the mold opening and closing action will cause the insert to loosen, fall off, or shift. A slight error will cause overflow, resulting in discontinuous production process and failure to mass produce, and a high product scrap rate. The production efficiency is low and the production cost is seriously wasted.

[0005] In summary, the problems existing in the production process of full-encapsulation injection molding of automotive battery component insert products are as follows;

[0006] (1) The injection molding process cannot be accurately and efficiently positioned;

[0007] (2) The insert has no support during injection molding and bends and deforms.

[0008] In view of this, this application is hereby filed. Summary of the invention

[0019] The insert product fixing structure includes a slider insert and a second insert pin. The second insert pin passes through the slider insert and the other end is connected to the second slider. A rectangular spring is arranged between the second insert pin and the second slider.

[0020] A spring groove is set on the second slider corresponding to the rectangular spring, and the rectangular spring is installed in the spring groove and pressed against the bottom surface of the second insert. A second insert is set on the slider insert, and the second insert is set in a T shape. The slider insert and the second insert are provided with mounting grooves corresponding to each other. One end of the second insert is fixed in the mounting groove, and a positioning protrusion is formed on the other end. The upper template of the secondary injection molding mold is provided with a positioning groove corresponding to the positioning protrusion.

[0021] A method for injection molding an automotive battery component insert product comprises the following steps:

[0022] S1: placing the insert metal plate into the first cavity of the one-shot injection molding mold, performing one-shot injection molding, and coating the surface of the insert metal plate with a nylon glass fiber layer. Due to the presence of the positioning groove, a cylindrical boss is formed on the nylon glass fiber layer after injection molding, and the cylindrical boss is coated on the surface of the insert metal plate in the form of a "hinge". After one-shot injection molding, an insert semi-finished product with a positioning cylindrical boss is obtained, which provides a support point for the secondary injection molding mold;

[0023] S2: Place the insert semi-finished product prepared in step S1 in a secondary injection molding mold, place the insert in the secondary injection molding mold, close the mold, fix the insert semi-finished product with the insert product fixing assembly, install the insert to the insert semi-finished product through the insert installation assembly, and then perform secondary injection molding to prepare a fully encapsulated battery component insert product.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) The present invention sequentially arranges a primary injection molding mold and a secondary injection molding mold, and after the primary injection molding, a nylon glass fiber coating layer with positioning protrusions is coated on the surface of the metal plate, thereby solving the difficulty that the product insert aluminum plate has no positioning and support in the secondary injection molding mold. The secondary injection mold is provided with an insert product fixing component and an insert installation component, thereby solving the structural form of successful molding of the secondary injection molding under limited space, overcoming the quality abnormalities such as displacement of the insert aluminum plate and deformation of the aluminum plate due to injection molding pressure in the prior art, realizing precise positioning of the insert, improving product production efficiency and product precision, and reducing production costs.

[0026] (2) A positioning pin and a positioning insert are arranged on the upper mold core of the one-shot injection molding mold. The aluminum plate is positioned by the conical positioning insert. The positioning insert and the positioning pin are contoured according to the positioning hole of the aluminum plate itself, thereby realizing accurate positioning of the aluminum plate and facilitating injection molding.

[0027] (3) A plurality of split top blocks are arranged on the upper mold core of the one-time injection molding mold, including a first top block and a second top block. A spring is arranged on the first top block. When the mold is opened and closed, the limit bolt limits the distance between the upper mold core and the second top block. The first top block is driven by the spring to be installed and matched with the insert product and the metal aluminum plate. This assembly space and installation matching structure solves the problem of uneven placement of the aluminum plate and lack of gripping position for the robot when installing the aluminum plate.

[0028] (4) The secondary injection molding mold adds an insert product fixing component and an insert installation component to ensure that the insert can be accurately positioned in the mold and is not prone to loosening when the mold is in motion, thereby ensuring the mold production efficiency.

[0029] (5) The insert fixing assembly includes an insert sleeve, an insert pin and a support sleeve. A strong magnet is fixed inside the support sleeve. The support sleeve fits with the bottom of the insert pin. A cushion column is arranged between the insert sleeve and the L-shaped plate. The strong magnet contacts the insert pin and transmits the magnetic force to the insert pin. The magnetic force prevents the insert from falling off during the movement of the mold opening and closing slider. At the same time, a rounded corner is set at the top of the insert pin after the corner is cut and it is higher than the insert. When the insert is placed in the early stage, the front end of the insert hole is introduced first, which solves the installation difficulty problem caused by the error of the insert installation position in the early stage.

[0030] (6) The insert product fixing assembly includes a slider insert and a second insert pin. The positioning slider insert and the slider body are designed to be split, which is convenient for the maintenance and replacement of the second insert pin.

[0031] (7) A rectangular spring support is provided at the bottom of the second insert pin to change the contact between the insert and the second insert pin into an elastic contact. The second insert pin compensates for the insert size error under the action of the rectangular spring, thereby solving the problem of mold interference and mold overflow caused by inconsistent insert height dimensions.

The insert product fixing component 300 and the insert installation component 400 are respectively arranged on both sides of the second upper mold core 201 and the second lower mold core 202. The second upper mold core 201 and the second lower mold core 202 are matched to form a second cavity 203.

[0061] Open the mold, place the semi-finished insert molded by the primary injection molding mold in the second cavity 203, install the insert 800 on the semi-finished insert, close the mold, fix the insert product fixing component 300 on the semi-finished insert, and the insert product fixing component 300 installs the insert 800 on the semi-finished insert. After completion, inject through the secondary injection molding channel and inject on the surface of the semi-finished insert to form a product.

[0062] The insert installation assembly 400 includes a first locking block 401, a first slider 402, an insert fixing assembly 500 and a driving member 403. One end of the insert fixing assembly 500 passes through the first slider 402, and the other end is connected to the driving member 403. One end of the first slider 402 corresponds to the insert product fixing assembly 300, and the other end is connected to the driving member 403. The driving member 403 is a driving cylinder.

First pressure strips 404 are arranged on both sides of the first slider 402.

[0063] A mounting block 204 is arranged on the lower mold plate of the secondary injection molding mold corresponding to the insert mounting assembly 400, and the mounting block 204 is a "concave" structure, and the driving cylinder corresponds to the groove of the mounting block 204; guide rods 205 are arranged on both sides of the driving cylinder, one end of the guide rod 205 is connected to the first slider 402, and the other end is arranged with a sensing block 206, and a travel switch 207 is arranged on the mounting block 204, and the travel switch 207 corresponds to the sensing block 206.

[0064] Specifically, the insert fixing assembly 500 is fixed to the first slider 402 through the L-shaped plate 431. The other end of the L-shaped plate 431 is connected to the piston rod of the driving cylinder, and the insert 800 and the first slider 402 move synchronously through the action of the driving cylinder, and the first slider 402 moves accurately under the guidance of the first pressure strip 404.

[0065] The insert fixing assembly 500 includes a first needle insert sleeve 501, a first needle insert 502 arranged in the first needle insert sleeve 501, and a support sleeve 503. A strong magnet 504 is fixed in the support sleeve 503. The support sleeve 503 is fitted with the bottom of the first needle insert 502. A cushion column 505 is arranged between the first needle insert sleeve 501 and the L-shaped plate 431.

[0073] A method for injection molding an automotive battery component insert product comprises the following steps:

[0074] S1: Put the insert metal plate 600 into the first cavity 121 of the one-shot injection molding mold, perform one-shot injection molding, and inject and coat the nylon glass fiber layer 700 on the surface of the insert metal plate 600. Due to the presence of the positioning groove 122, a cylindrical positioning boss 1 is formed on the nylon glass fiber layer 700 after injection molding. The cylindrical positioning boss 1 is coated on the surface of the insert metal plate 600 in the form of a "hinge" 2. After one-shot injection molding, an insert semi-finished product with a positioning cylindrical boss is obtained, which provides a support point for the secondary injection molding mold.

[0075] S2: Place the insert semi-finished product prepared in step S1 in a secondary injection molding mold, place the insert in the secondary injection molding mold, close the mold, fix the insert semi-finished product with the insert product fixing component 300, install the insert 800 to the insert semi-finished product through the insert installation component 400, and perform secondary injection molding to prepare a fully encapsulated battery component insert product.

[0076] Working principle of overmolding:

[0077] (1) During the primary injection molding, the insert product, i.e., the metal aluminum plate, is placed in the mold in the open state. When the mold is opened, the first ejector block 103 will pop out the first upper mold core 101 along the inclination direction under the action of the spring 106, and the limit bolt 105 limits the ejection distance of the second ejector block. This assembly space and structure solves the problem that the aluminum plate is not placed flat and the robot has no gripping position when installing the aluminum plate. In addition, the insert product, i.e., the metal aluminum plate, is precisely positioned through its own positioning holes and the mold positioning pins 108 and positioning inserts 109. The mold is closed so that the first ejector block 103, the second ejector block and the insert product, i.e., the metal aluminum plate, are reset at the same time.

[0078] The mold gate is opened toward the first cavity 121, and a positioning boss 1 is added to the insert product, i.e., the metal aluminum plate, during injection molding, i.e., a layer of positioning "hinge" 2 is coated on the metal aluminum plate. Specifically, a layer of nylon glass fiber material is coated on the metal plate, and the boss is coated and fixed on the metal plate in the form of a "hinge".

[0079] Overmolding:

[0080] During the second injection molding, the positioning "hinge" 2 with the positioning boss 1 provides a support point for the injection molding process, solving the problem of the aluminum plate being offset and the aluminum plate being deformed under pressure.

[0081] The semi-finished insert after one injection molding is placed in the second cavity 203 of the mold, and the mold is closed. During the mold closing process, under the action of the inclined guide column 303, the second slider 302 moves laterally, further driving the slider insert 305 to move laterally. Further, the second insert pin 306 moves under the action of the slider insert 305 and the second slider 302. Further, one end of the second insert pin 306 and the slider insert 305 work together to the insert product to fix one side of the insert product. At this time, the driving cylinder is started, driving the second slider 302 and the insert fixing assembly 500 to move together, pushing the insert 800 into the semi-finished insert, and completing the injection molding; cycle.

[0082] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
