Description

Technical Field

[0001] The present invention relates to the technical field of mold demoulding, and in particular to a processing mold which is convenient for demoulding and a use method thereof. Background Art

[0002] A mold is a device for processing and producing products of specific shapes. Injection molds are one of the common molds. After the injection mold is closed, the extruder injects the molten plastic into the cavity in the mold through the injection hole until the product is cooled and formed in the cavity. At this time, the molded product can be ejected from the mold through the ejector mechanism in the mold. However, the ejector pins of the ejector mechanism are now set at the bottom of the cavity. As a result, after the product is formed, no matter how much the product sticks to the cavity, the bottom end of the product will also stick to the ejector pin. When the ejector pin rises to lift the product, the product will still stick to the ejector pin. After the product is separated from the cavity, the operator still needs to remove the product with force to separate the product from the ejector pin. This process can easily cause damage to the part where the product is adhered to the ejector pin, thereby reducing the stability and convenience of mold demolding. Summary of the Invention

[0017] The present invention also provides a method for using a processing mold that is easy to demould, comprising the following steps:

[0018] Step 1: Connect the external extrusion equipment to the injection hole, and then inject the molten plastic material into the first cavity and the second cavity through the injection hole. After filling, the molten plastic in the first cavity and the second cavity is cooled and formed, and then the movable mold is moved upward by the external equipment;

[0019] Step 2: The hydraulic cylinder works to drive the connecting plate to rise. The hydraulic cylinder limits the connecting block through the clamping hole, so that the connecting plate rises and the connecting frame rises synchronously. The rising of the connecting frame drives multiple first push rods to rise. The rising of the first push rod drives the first clamping block to rise. The rising of the first clamping block can lift the product formed in the second cavity for demoulding. At the same time, under the limit of the two limit rods, the second push rod is kept stationary in the second insertion hole, and the rising product is separated from the second clamping block. As the hydraulic cylinder continues to work, the connecting plate rises and drives the fixed rod to rise. The rising of the fixed rod drives the extrusion block to rise until the extrusion block rises and the circular table contacts the third spring. At the same time, as the extrusion block slowly rises, and under the elastic force of the third spring on the first limiting ring, the limiting rod slowly moves into the second active cavity until the limiting rod is completely immersed in the third active hole. At this time, the two third active holes no longer limit the second push rod. At the same time, the extrusion block is against the top of the inner wall of the second active cavity, which can make the extrusion block rise and drive the second push rod to rise in the second insertion hole, so that the second clamping block rises;

[0020] Step 3: The connecting frame and the connecting plate continue to rise, so that the first push rod and the second push rod both rise until the connecting frame rises so that the fixing column passes through the connecting groove and is inserted into the slot, and the third inclined surface contacts the second inclined surface. As the connecting frame continues to rise, the third inclined surface is squeezed against the second inclined surface, and the unlocking rod moves in the clamping hole. The unlocking rod moves to squeeze the clamping block, and at the same time, the unlocking rod moves to compress the second spring until the fixing column is fully inserted into the slot. At this time, the unlocking rod just squeezes the clamping block into the clamping hole. At this time, the connection between the connecting frame and the connecting plate is released, and the connecting frame no longer moves up. As the hydraulic cylinder works, the connecting plate continues to move up, thereby causing the second push rod to continue to move up until the second clamping block contacts the bottom end of the product, and as the second clamping block continues to move up, the product will be separated from the first clamping block. At this time, the product is completely demoulded, and the staff can easily remove the product.

[0021] Step 4: After the product is removed, the hydraulic cylinder works to drive the connecting plate to move downward, and the downward movement of the connecting plate drives the extrusion block to move downward. The downward movement of the extrusion block will cause the second push rod to move downward until the second push rod moves downward, causing the two limit rods to move into the installation cavity. At this time, the limit rod is squeezed by the outer wall of the extrusion block, so that the limit rod is squeezed out of the third movable hole. At the same time, as the connecting plate continues to move downward, the first inclined surface on the clamping block will contact and squeeze the arc chamfer, so that the clamping block slowly shrinks into the first movable hole and squeezes the first spring until the clamping block moves to align with the clamping hole. At this time, under the elastic force of the first spring, the clamping block is popped out and inserted into the clamping hole, so that the connecting plate is connected to the connecting frame.

[0022] The technical effects and advantages of the present invention are as follows:

[0023] (1) The present invention utilizes the arrangement of the ejection mechanism, the connection mechanism and the limit mechanism, so that the first ejector rod in the ejection mechanism first rises to cause the first clamping block to lift the product and separate the product from the second clamping block, and then the first ejector rod stops rising to cause the second ejector rod to rise to cause the second clamping block to rise and lift the product upward and separate the product from the first clamping block, so that the product can be completely separated from the mold and no longer adhered when demoulding, thereby improving the stability and convenience of product demoulding;

[0024] (2) The present invention utilizes the setting of the unlocking mechanism to make the connection frame rise so that the fixing column passes through the connecting groove and is inserted into the slot so that the third inclined surface presses the second inclined surface, thereby making the unlocking rod move in the clamping hole and press the clamping block, so that the clamping block is separated from the clamping hole, thereby separating the connection plate from the connection frame, and improving the convenience of separating the connection plate from the connection frame;

[0025] (3) The present invention utilizes the arrangement of an extrusion block and a limiting rod. The extrusion block squeezes the limiting rod so that the limiting rod is inserted into the third movable hole. The two inserted limiting rods limit the second push rod, preventing the second push rod from rising and moving upward in the second insertion hole, thereby improving the working stability of the second push rod.

[0045] Working principle of the present invention:

[0046] The external extrusion equipment is connected to the injection hole 15, and then the molten plastic material is injected into the first cavity 13 and the second cavity 14 through the injection hole 15. After filling, the molten plastic in the first cavity 13 and the second cavity 14 is cooled and formed. Then the movable mold 11 is moved up by the external equipment, and the hydraulic cylinder 38 works so that the hydraulic cylinder 38 drives the connecting plate 32 to rise. The hydraulic cylinder 38 limits the clamping block 34 through the clamping hole 37, so that the connecting plate 32 rises and drives the connecting frame 31 to rise synchronously. The rising of the connecting frame 31 drives the multiple first ejector rods 22 to rise. The rising of the first ejector rod 22 drives the first clamping block 24 to rise. The rising of the first clamping block 24 can lift the product formed in the second cavity 14 for demoulding. At the same time, under the limitation of the two limiting rods 72, When the locking cam 75 is in the unlocked position, the locking cam 73 is in the unlocked position, and the locking cam 73 is in the unlocked position, so that the second locking cam 73 is unlocked and the second locking cam 73 is unlocked. The rod 26 rises in the second insertion hole 25, causing the second clamping block 28 to rise, and the connecting frame 31 and the connecting plate 32 continue to rise, causing the first push rod 22 and the second push rod 26 to rise until the connecting frame 31 rises so that the fixing column 55 passes through the connecting groove 54 and is inserted into the slot 52, and the third inclined surface 56 contacts the second inclined surface 53. As the connecting frame 31 continues to rise, the third inclined surface 56 squeezes the second inclined surface 53 and causes the unlocking rod 51 to move in the engaging hole 37. The unlocking rod 51 moves to squeeze the engaging block 34. At the same time, the unlocking rod 51 moves to compress the second spring 65 until the fixing column 55 is fully inserted into the slot 52. At this time, the unlocking rod 51 just squeezes the engaging block 34 into the engaging hole 37, and the connecting frame 3 is released. 1 is connected to the connecting plate 32, the connecting frame 31 no longer moves up, and with the operation of the hydraulic cylinder 38, the connecting plate 32 continues to move up, thereby causing the second push rod 26 to continue to move up until the second clamping block 28 abuts the bottom end of the product, and as the second clamping block 28 continues to move up, the product will be separated from the first clamping block 24. At this time, the product is completely demoulded and the staff can easily remove the product. After the product is removed, the hydraulic cylinder 38 works to drive the connecting plate 32 downward, and the downward movement of the connecting plate 32 drives the extrusion block 74 downward. The downward movement of the extrusion block 74 will cause the second push rod 26 to move downward until the second push rod 26 moves downward, causing the two limiting rods 72 to move into the installation cavity 39. At this time, the limiting rod 72 is squeezed out of the third movable hole 71 by the outer wall of the extrusion block 74.At the same time, as the connecting plate 32 continues to move downward, the first inclined surface 35 on the clamping block 34 contacts and squeezes the arc chamfer 36, causing the clamping block 34 to slowly retract into the first movable hole 33 and squeeze the first spring 41 until the clamping block 34 moves to align with the clamping hole 37. At this time, under the elastic force of the first spring 41, the clamping block 34 is ejected and inserted into the clamping hole 37, thereby connecting the connecting plate 32 to the connecting frame 31.

9. The method for using a processing mold that is easy to demould according to claim 8, characterized in that: The following steps are involved: Step 1: Connecting the external extrusion device to the injection hole (15), and then injecting the molten plastic material into the first cavity (13) and the second cavity (14) through the injection hole (15). After the injection, the molten plastic in the first cavity (13) and the second cavity (14) is cooled and formed, and then the movable mold (11) is moved upward by the external device; Step 2: The hydraulic cylinder (38) works so that the hydraulic cylinder (38) drives the connecting plate (32) to rise. The hydraulic cylinder (38) limits the clamping block (34) through the clamping hole (37), so that the connecting plate (32) rises and drives the connecting frame (31) to rise synchronously. The rising of the connecting frame (31) drives the plurality of first ejector rods (22) to rise. The rising of the first ejector rod (22) drives the first clamping block (24) to rise. The rising of the first clamping block (24) can lift the product formed in the second cavity (14) for demoulding. At the same time, under the limitation of the two limiting rods (72), the second ejector rod (26) is fixed in the second jack (25), and the rising product is separated from the second clamping block (28). As the hydraulic cylinder (38) continues to work, the connecting plate (32) rises and drives the first ejector rod (22) to rise. The fixed rod (77) rises, and the fixed rod (77) rises and drives the extrusion block (74) to rise until the extrusion block (74) rises so that the round table (75) contacts the third spring (83). At the same time, as the extrusion block (74) slowly rises, and under the elastic force of the third spring (83) on the first limiting ring (82), the limiting rod (72) slowly moves into the second movable cavity (73) until the limiting rod (72) is completely immersed in the third movable hole (71). At this time, the two third movable holes (71) no longer limit the second push rod (26). At the same time, the extrusion block (74) is against the top of the inner wall of the second movable cavity (73), so that the extrusion block (74) rises and drives the second push rod (26) to rise in the second jack (25), so that the second clamping block (28) rises; Step 3: The connecting frame (31) and the connecting plate (32) continue to rise, so that the first push rod (22) and the second push rod (26) are both raised, until the connecting frame (31) rises to the point where the fixing column (55) passes through the connecting groove (54) and is inserted into the slot (52), and the third inclined surface (56) contacts the second inclined surface (53). As the connecting frame (31) continues to rise, the third inclined surface (56) presses the second inclined surface (53), and the unlocking rod (51) moves in the clamping hole (37). The unlocking rod (51) moves to press the clamping block (34), and at the same time, the unlocking rod (51) moves to press the second spring (6 5) is compressed until the fixing column (55) is completely inserted into the slot (52), at which time the unlocking rod (51) just squeezes the clamping block (34) into the clamping hole (37), and the connection between the connecting frame (31) and the connecting plate (32) is released. The connecting frame (31) no longer moves upward, and as the hydraulic cylinder (38) works, the connecting plate (32) continues to move upward, thereby causing the second push rod (26) to continue to move upward until the second clamping block (28) abuts against the bottom end of the product, and as the second clamping block (28) continues to move upward, the product will be separated from the first clamping block (24), and the product will be completely demoulded, and the staff can easily remove the product; Step 4: After the product is removed, the hydraulic cylinder (38) works to drive the connecting plate (32) to move downward, and the connecting plate (32) moves downward to drive the extrusion block (74) to move downward. The extrusion block (74) moves downward, which causes the second push rod (26) to move downward until the second push rod (26) moves downward, causing the two limiting rods (72) to move into the installation cavity (39). At this time, the limiting rod (72) is squeezed by the outer wall of the extrusion block (74), causing it to be squeezed out of the third movable hole (71). At the same time, as the connecting plate (32) continues to move downward, The first bevel (35) on the clamping block (34) contacts and squeezes the arc chamfer (36), causing the clamping block (34) to slowly shrink into the first movable hole (33) and squeeze the first spring (41) until the clamping block (34) moves to align with the clamping hole (37). At this time, under the elastic force of the first spring (41), the clamping block (34) is ejected and inserted into the clamping hole (37), so that the connecting plate (32) is connected to the connecting frame (31).
