Description

Technical Field

[0001] This utility model belongs to the field of electrical device technology, and in particular relates to an integrated control module for use in injection molding machines. Background Technology

[0002] An injection molding machine is a mechanical device that heats plastic material (usually in granular form) to a molten state, injects it into a mold cavity under high pressure, and then cools and solidifies it to form the desired plastic product. Modern injection molding machines mostly use computer control technology to achieve automated operation and monitoring.

[0003] However, under the current technology, the control module (mainly a circuit board) of the injection molding machine is often directly placed in the cavity inside the injection molding machine. The electrical wiring is relatively scattered and cannot be integrated into a single unit. This makes later maintenance and repair more difficult. At the same time, the control module lacks external structural support and protection. Under high-speed operation or high-pressure injection conditions, the control module is easily damaged by shaking or collision. Utility Model Content

[0027] The integrated control module for injection molding machines proposed in this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this utility model will become clearer from the following description and claims.

[0028] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0029] See Figures 1-5 This embodiment provides an integrated control module for use in injection molding machines, the main structure of which includes a base plate 1, a cover plate 2 and a circuit board 3.

[0030] In this embodiment, the base plate 1 is generally a rectangular structure. For ease of understanding, the length direction of the base plate 1 is defined as the first direction. The base plate 1 has a first bending portion 11 at both ends of the first direction, which bends toward the cover plate 2. Similarly, the cover plate 2 is also generally a rectangular structure. The width direction of the cover plate 2 is defined as the second direction (since the length and width directions of the base plate 1 and the cover plate 2 need to be consistent, the first direction is also the length direction of the cover plate 2, and the second direction is also the width direction of the base plate 1). The cover plate 2 has a second bending portion 21 at both ends of the second direction, which bends toward the base plate 1.

[0031] The base plate 1 and the cover plate 2 are detachably and fixedly connected. After the base plate 1 and the cover plate 2 are assembled, the first bending part 11 forms a block at both ends of the cover plate 2 in the first direction, and the second bending part 21 forms a block at both ends of the base plate 1 in the second direction, forming a relatively closed accommodating space between the base plate 1 and the cover plate 2. That is, after the assembly, the base plate 1 and the cover plate 2 form a cuboid structure with an internal hollow interior.

[0032] The circuit board 3 is equipped with several electronic components and printed circuits. The circuit board 3 is arranged in the accommodating space and is fixedly connected to the cover plate 2. The circuit board 3 is used to control the operation of the injection molding machine and realize the automated operation and operation status monitoring of the injection molding machine.

[0033] Therefore, in this embodiment, after the base plate 1, cover plate 2 and circuit board 3 are assembled, they form an integrated structure, which facilitates the quick installation and disassembly of the control module inside the injection molding machine. At the same time, the base plate 1 and cover plate 2 can provide sufficient structural support and protection for the internal circuit board 3, effectively preventing the circuit board 3 from being damaged by shaking or external structural collision and squeezing.

[0034] The following will provide a more detailed description of the specific structure and functions of the integrated control module for injection molding machines provided in this embodiment:

[0035] Preferably, in one embodiment, the width of the base plate 1 along the second direction is smaller than the width of the cover plate 2 along the second direction, and the base plate 1 is configured to be arranged in the interval formed opposite to the second bend 21.

[0036] In this embodiment, the width of the base plate 1 is slightly smaller than the width of the cover plate 2. During the assembly process, the base plate 1 can be moved horizontally along the length direction of the cover plate 2, within the interval formed by the two sets of second bending portions 21, to a position corresponding to the cover plate 2, or the base plate 1 and the cover plate 2 can be directly fastened together along the length and width directions to achieve quick alignment of the base plate 1 and the cover plate 2. At the same time, it can ensure that the second bending portion 21 is located on the outer edge of the base plate 1, thereby providing protection for the side of the circuit board 3.

[0037] Preferably, in one embodiment, the first bending portion 11 has a folded edge 12 at the end away from the base plate 1. The folded edge 12 fits against the cover plate 2. The folded edge 12 has a plurality of first fixing holes. After the base plate 1 and the cover plate 2 are assembled, the cover plate 2 has a plurality of second fixing holes on both sides in the first direction that are opposite to the positions of the first fixing holes. A connector passes through the first fixing holes and the second fixing holes to fix and connect the base plate 1 and the cover plate 2. The connector includes bolts, screws and other combined components.

[0038] Preferably, in one embodiment, the second bending portion 21 is provided with a plurality of hook portions 22 at the end away from the cover plate 2, and the edge of the circuit board 3 is provided with a plurality of flanges 31 adapted to the hook portions 22. The overall width of the circuit board 3 including the flanges 31 is adapted to the width of the cover plate 2. The circuit board 3 is configured such that the flanges 31 are correspondingly engaged in the hook cavity 223 of the hook portion 22.

[0039] In this embodiment, when the cover plate 2 is placed horizontally, the hook part 22 includes a vertically arranged connecting section 221 and a horizontally arranged fixing section 222. The length of the fixing section 222 is greater than the width of the connecting section 221. Therefore, the edge of the fixing section 222 will form a horizontal groove with the edge of the cover plate 2, namely the hook cavity 223. The width of the hook cavity 223 is adapted to the thickness of the circuit board 3 (i.e. the thickness of the flange 31), so that the flange 31 of the circuit board 3 can be engaged in the hook cavity 223 of the hook part 22, realizing the quick positioning and fixed connection between the circuit board 3 and the cover plate 2. At the same time, in order to fully ensure the connection between the circuit board 3 and the cover plate 2, the circuit board 3 is also provided with a connecting hole, and the circuit board 3 and the cover plate 2 are further fixedly connected through the connector.

[0040] Preferably, in one embodiment, the width of the circuit board 3 along the second direction is greater than the width of the base plate 1 along the second direction. The circuit board 3 has a plurality of sockets 32 arranged toward the base plate 1 at both ends of its second direction, and the length extension direction of the sockets 32 is located in the interval formed between the edge of the circuit board 3 and the edge of the base plate 1.

[0041] In this embodiment, the socket 32 ​​in the circuit board 3 is electrically connected to electronic components (such as the main control chip) through printed circuits. The socket 32 ​​is used to provide a connection interface to the external electrical devices of the injection molding machine (such as displays, buttons, sensors, etc.). The width of the circuit board 3 is greater than the width of the base plate 1, and the length extension direction of the socket 32 ​​is located in the gap formed by the edge of the circuit board 3 and the edge of the base plate 1. That is, the width of the gap formed by the edge of the circuit board 3 and the edge of the base plate 1 is greater than the width of the socket 32. The base plate 1 does not block the length extension direction of the socket 32, so that the cables of the external electrical devices of the injection molding machine can be directly connected to the socket 32 ​​of the circuit board 3, thereby improving the electrical assembly efficiency.

[0042] Preferably, in one embodiment, the base plate 1 has electrical markings corresponding to several sockets 32 on both ends in the second direction and on the side facing away from the circuit board 3, so that after the control module is assembled, the operator can quickly locate the several sockets 32 from the outside of the base plate 1.

[0043] Preferably, in one embodiment, a first heat dissipation area 13 is provided in the base plate 1. The first heat dissipation area 13 is composed of several circular through holes. Several electronic components of the circuit board 3 include a main control chip. Several electronic components in the circuit board 3 are arranged facing the base plate 1. The positions of the first heat dissipation area 13 and the main control chip are arranged opposite to each other. The first heat dissipation area 13 can assist the main control chip in achieving rapid heat dissipation.

[0044] Preferably, in one embodiment, a second heat dissipation area 14 is provided in the first bending portion 11. The second heat dissipation area 14 is composed of a plurality of rectangular through holes. The second heat dissipation area 14 is used to further improve the gas flow between the accommodating space and the external space, and to assist the circuit board 3 in heat dissipation.

[0045] Preferably, in one embodiment, the circuit board 3 includes several electronic components including an Ethernet port 33, and a connection through hole 15 is provided in the base plate 1. The connection through hole 15 and the Ethernet port 33 are arranged opposite to each other, so that the network cable of the external electrical device of the injection molding machine can pass through the base plate 1 and connect to the Ethernet port 33 in the circuit board 3.

[0046] Preferably, in one embodiment, the base plate 1 and the cover plate 2 are made of hot-dip galvanized cold-rolled steel sheet. Hot-dip galvanized cold-rolled steel sheet has better strength and corrosion resistance, and its ductility is also better. In this embodiment, the base plate 1 and the cover plate 2 are both integral steel plates. Using hot-dip galvanized cold-rolled steel sheet can realize the bending and punching of the base plate 1 and the cover plate 2.

[0047] In summary, this embodiment provides an integrated control module for an injection molding machine, comprising a base plate 1 and a cover plate 2. The base plate 1 and cover plate 2 are joined to form an accommodating space, within which a circuit board 3 is fixed. In this embodiment, the base plate 1, cover plate 2, and circuit board 3 form an integrated structure that can be detachably installed inside the injection molding machine. When maintenance or repair of the circuit board 3 is required, the integrated structure formed by the base plate 1, cover plate 2, and circuit board 3 can be completely removed from the injection molding machine without excessive disassembly of the machine body, effectively improving the efficiency of circuit board 3 maintenance and repair. Simultaneously, a robust connection is formed between the base plate 1 and cover plate 2, and components such as the first bending portion 11 and the second bending portion 21 provide ample protection for the circuit board 3, effectively preventing damage caused by shaking or external structural impacts and pressure. In addition, the base plate 1 and the cover plate 2 are provided with a heat dissipation area, a space for cable connection socket 32, and a connection through hole 15 for Ethernet port 33 for network cable connection, which effectively improves the heat dissipation performance of the control module and facilitates the electrical connection of the control module.
