Description

Technical Field

[0001] This utility model relates to the field of injection molding, and specifically refers to an embedded injection molding machine brake mechanism. Background Technology

[0002] Injection molding machines are commonly used plastic machinery for producing plastic products. During production, a molding die is installed on the injection molding machine, and the plastic product is formed in the molding die. The product requires a lot of molding pressure during molding, so injection molding machines are basically equipped with a mold clamping device to withstand the molding pressure of the molding die.

[0003] Although many mold-locking devices have appeared on the market, such as the rotary injection molding machine with mold-locking function that our company previously applied for, with application number CN201910888700.1, the brake cylinder is located on the outside of the outer and inner brake blocks, which results in a large overall size of the brake mechanism and limited use. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an embedded injection molding machine brake mechanism.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an embedded injection molding machine brake mechanism, comprising two parallel slide rails, an outer brake block and an inner brake block with their ends slidably disposed on the two slide rails respectively, two stop bars parallel to the outer and inner brake blocks, at least one cavity horizontally disposed within the inner brake block and parallel to the slide rails, and a piston rod slidably disposed within the cavity and connected at one end to the outer brake block.

[0006] Preferably, the cavity has open ends; the outer end of the inner gate block is provided with an outer end cap for sealing the outer end opening of the cavity, and the inner end is embedded with an inner end cap for sealing the inner end opening of the cavity; the piston rod passes through the inner end cap.

[0007] Preferably, sealing rings are provided between the outer end cover and the inner gate block, between the inner end cover and the inner gate block, between the piston rod and the inner wall of the cavity, and between the inner end cover.

[0008] Preferably, the outer end cover and the inner end cover are connected to the inner gate block by multiple bolts.

[0009] Preferably, at least one spring is provided between the outer and inner brake blocks, which is placed parallel to the slide rail, to drive the outer and inner brake blocks to open.

[0010] Preferably, it also includes at least one guide rod that is placed parallel to the slide rail and passes through the inner gate block and connects to the outer gate block.

[0011] Preferably, both the piston rod and the guide rod partially extend into the outer brake block; the outer end of the outer brake block is provided with connecting holes corresponding to the piston rod and the guide rod, and the connecting piston rod and the guide rod are connected to the outer brake block by bolts passing through the connecting holes.

[0012] Preferably, it further includes a position detection component; the guide rod extends out of the inner gate block; the position detection component includes a sensing part disposed at the outer end of the guide rod and a sensor for detecting the sensing part.

[0013] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0014] This invention, by embedding the brake cylinder within the inner brake block, makes the brake mechanism structure more compact, thereby reducing the overall volume of the brake mechanism and making it more suitable for space-constrained locking brake applications. It also has the advantages of easy installation. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] Appendix Figure 1-4The embedded injection molding machine brake mechanism of this utility model includes two parallel slide rails 1 arranged on the upper template 11 and located on the front and rear sides of the brake rod 12; an outer brake block 2 and an inner brake block 3 respectively slidably arranged on the two slide rails 1 and located on the left and right sides of the brake rod 12; two stop rods 4 arranged parallel on the upper template 11 and located outside the outer brake block 2 and the inner brake block 3 respectively; at least one cavity 31 horizontally arranged in the inner brake block 3 and placed parallel to the slide rails 1; and a piston rod 5 slidably arranged in the cavity 31 and connected at one end to the outer brake block 2. The two stop rods 4 are placed perpendicular to the slide rails 1, and their distance is the sum of the width of the outer brake block 2 and the inner brake block 3 and the travel of the piston rod 5. The distances from the two stop rods 4 to the left and right brake blocks are the same.

[0023] When the brake is engaged: By injecting hydraulic oil into the right end of cavity 31, the piston rod 5 moves to the left, causing the outer brake block 2 and inner brake block 3 to move closer to each other and lock against the left and right sides of the brake rod 12 respectively. Figure 3-4 As shown, the mold is locked; when the brake needs to be released: by injecting hydraulic oil into the left end of the cavity 31, the piston rod 5 can be moved to the right, so that the outer brake block 2 and the inner brake block 3 are separated from each other. At the same time, under the limit of the two stop rods 4, the outer brake block 2 and the inner brake block 3 are separated from the left and right sides of the brake rod 12 respectively, thus releasing the brake.

[0024] In this embodiment, the cavity 31 is provided in two places, located on the front and rear sides of the brake rod 12 respectively, so that the force is more even when braking and the braking effect is better.

[0025] Furthermore, the cavity 31 has open ends for easy processing; the outer end of the inner brake block 3 is provided with an outer end cap 6 for sealing the outer end opening of the cavity 31, and the inner end is embedded with an inner end cap 7 for sealing the inner end opening of the cavity 31, which facilitates installation; the piston rod 5 passes through the inner end cap 7; the inner end cap 7 does not protrude from the inner end of the inner brake block 3, so that the outer brake block 2 and the inner brake block 3 can fit tightly when braking.

[0026] Furthermore, sealing rings are provided between the outer end cover 6 and the inner gate block 3, between the inner end cover 7 and the inner gate block 3, between the piston rod 5 and the inner wall of the cavity 31, and between the inner end cover 7, resulting in a good sealing effect.

[0027] Furthermore, the outer end cover 6 and the inner end cover 7 are respectively connected to the inner gate block 3 by multiple bolts, which facilitates installation and maintenance.

[0028] Furthermore, at least one spring 8 is provided between the outer brake block 2 and the inner brake block 3, which is placed parallel to the slide rail 1. When the brake is released, the outer brake block 2 and the inner brake block 3 can be quickly separated, thereby improving work efficiency.

[0029] In this embodiment, two springs 8 are provided, located on the front and rear sides of the brake rod 12 respectively, so that the force is more evenly distributed.

[0030] Furthermore, it also includes at least one guide rod 8 placed parallel to the slide rail 1 and passing through the inner gate block 3 and connecting the outer gate block 2, which serves as a guide.

[0031] In this embodiment, two guide rods 8 are provided, located on the front and rear sides of the brake rod 12 respectively, so that the force is more evenly distributed.

[0032] Furthermore, both the piston rod 5 and the guide rod 8 extend partially into the outer gate block 2; the outer end of the outer gate block 2 is provided with connecting holes 21 corresponding to the piston rod 5 and the guide rod 8, respectively, and the connecting piston rod 5 and the guide rod 8 are connected to the outer gate block 2 by bolts passing through the connecting holes 21, which facilitates installation.

[0033] In this embodiment, the connecting hole 21 is a stepped hole, so that the bolt connection will not protrude from the outer end of the outer gate block 2.

[0034] Furthermore, it also includes a position detection component 10; the guide rod 8 extends out of the inner gate block 3; the position detection component 10 includes a sensing part 101 disposed at the outer end of the guide rod 8, a bracket 102 disposed on the upper template 11, and a sensor 103 disposed on the bracket 102 for detecting the sensing part 101, so as to understand the position of the outer gate block 2 and the inner gate block 3 and perform control.

[0035] In this embodiment, the position of the bracket 102 on the upper template 11 can be adjusted along the axis of the guide rod 8, which not only facilitates installation but also reduces the machining accuracy.

[0036] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
