Technical Field

The utility model relates to the field of molds, in particular to a wear-resistant scraper mold.

Background Art

Conveyor rollers are widely used in the field of conveying. In order to remove the residual material adhering to the conveyor rollers, a scraper mechanism is configured to scrape the material. The existing scraper mechanism is usually set up with a highly wear-resistant scraper made of polyurethane material, and the scraper is driven by a driving member to scrape the material. When making a scraper, a special mold is required for casting and molding.

1 and 2 , a wear-resistant scraper plate mold according to an embodiment of the present invention is used to form a wear-resistant scraper plate 100 having a plurality of connecting holes 101 . The wear-resistant scraper plate mold includes: a mold assembly 200 and a forming rod group.

The mold assembly 200 includes a left half mold 210, a right half mold 220 and a cover mold 230. The left half mold 210 and the right half mold 220 are arranged opposite to each other on the left and right sides. The cover mold 230 is covered on the top of the left half mold 210 and the right half mold 220. A cavity is formed between the cover mold 230, the left half mold 210 and the right half mold 220. The cavity matches the contour of the wear-resistant scraper 100; the cover mold 230 is provided with a pouring port 231 to pour polyurethane material into the cavity. The mold assembly 200 is provided with multiple groups of molding holes 201 corresponding to the multiple connecting holes 101. One connecting hole 101 corresponds to a group of molding holes 201. The multiple groups of molding holes 201 are distributed at intervals in the front and back. A group of molding holes 201 includes three molding holes 201 extending left and right and aligned with each other. The three molding holes 201 in the same group are respectively arranged on the cover mold 230, the left half mold 210 and the right half mold 220. It should be noted that the front-to-back direction in this embodiment corresponds to the length direction of the wear-resistant scraper plate 100 , and the left-to-right direction corresponds to the thickness direction of the wear-resistant scraper plate 100 .

The forming rod group is provided with a plurality of insert rods 300, and the insert rods 300 are arranged corresponding to the forming holes 201, that is, one group of forming holes 201 corresponds to one insert rod 300, and the insert rods 300 are arranged through the three forming holes 201 of the same group, and are used to form the connection holes 101 of the wear-resistant scraper 100. Obviously, the insert rods 300 pass through the mold cavity; further, both ends of the insert rods 300 extend to the outside of the mold assembly 200 and one end of the insert rods 300 is provided with an operating handle 310. It should be noted that the above description is a description of the mold assembly 200 in a mold-closing state.

When in use, the left half mold 210, the right half mold 220 and the cover mold 230 are assembled together, and then multiple insertion rods 300 are passed through the corresponding forming holes 201 in turn, and the melted polyurethane material is added into the cavity from the pouring port 231 on the cover mold 230. Thereafter, the mold assembly 200 is placed in an insulation room for insulation until the polyurethane material is solidified and formed. After molding, the mold assembly 200 is taken out of the insulation room for cooling, and then the insertion rods 300 are removed, and then the left half mold 210, the right half mold 220 and the cover mold 230 are separated to take out the product.

The wear-resistant scraper plate mold of the embodiment of the utility model is provided with a left half mold 210, a right half mold 220 and a cover mold 230 to form a cavity therebetween, and forming holes 201 are provided on the left half mold 210, the right half mold 220 and the cover mold 230 corresponding to the connecting holes 101, and an insert rod 300 is provided to pass through the forming holes 201, so that the contour of the wear-resistant scraper plate 100 and a plurality of connecting holes 101 can be formed simultaneously by using the cavity and the insert rod 300, and the wear-resistant scraper plate 100 can be completely formed at one time, and no drilling operation is required subsequently, so that the product quality is high; by providing an operating handle 310 at one end of the insert rod 300, the insert rod 300 can be easily removed when demolding.

1 and 2 , it can be understood that the operating handle 310 extends radially along the insertion rod 300 and both ends of the operating handle 310 protrude from the outer peripheral wall of the insertion rod 300, that is, a T-shaped structure is formed between the operating handle 310 and the insertion rod 300. Such a configuration not only makes it convenient for the operator to insert and remove the insertion rod 300, but also makes it convenient for the operator to rotate the insertion rod 300. It is obvious that after the wear-resistant scraper 100 is formed, the insertion rod 300 may be adhered to the wear-resistant scraper 100. At this time, it may be difficult to pull out the insertion rod 300 by directly pulling it out, and the insertion rod 300 needs to be rotated for assistance. Therefore, the present embodiment provides an operating handle 310 with the above-mentioned structural form to facilitate the rotation and insertion and removal of the insertion rod 300.

1 and 2 , it can be understood that one of the left half mold 210 and the right half mold 220 is provided with at least two positioning protrusions 240 extending left and right, and the other is provided with a positioning hole 250 for inserting the positioning protrusion 240. By cooperating with the positioning protrusion 240 and the positioning hole 250, the left half mold 210 and the right half mold 220 can be quickly positioned and aligned when they are assembled, thus saving operation time.

Referring to FIGS. 1 to 3 , it can be understood that the wear-resistant scraper mold further includes a limiting structure, which includes an inserting portion 260, which is fixed to the cover mold 230, and the left half mold 210 and the right half mold 220 are both provided with a slot 202, and the slot 202 of the left half mold 210 and the slot 202 of the right half mold 220 are both vertically extended and open at the top, and the inserting portion 260 is simultaneously inserted into the slot 202 of the left half mold 210 and the slot 202 of the right half mold 220. , to horizontally limit the left half mold 210, the cover mold 230 and the right half mold 220, so as to avoid relative displacement in the horizontal direction between the left half mold 210, the cover mold 230 and the right half mold 220 during casting and molding, thereby affecting the quality of the molded product. Obviously, when splicing the left half mold 210, the cover mold 230 and the right half mold 220, the insertion part 260 is inserted from top to bottom into the slot 202 of the left half mold 210 and the slot 202 of the right half mold 220, which has a simple structure and is easy to splice.

1 and 2 , it can be understood that the insertion portion 260 is provided with a connecting plate 261, which is fixed to the front end or rear end of the cover mold 230, and vertically extending plug blocks 262 are fixedly provided on both sides of the connecting plate 261. The plug blocks 262 on the left and right sides of the connecting plate 261 are respectively used to insert into the slot 202 of the left half mold 210 and the slot 202 of the right half mold 220, so as to horizontally limit the left half mold 210, the cover mold 230 and the right half mold 220. An avoidance notch for avoiding the connecting plate 261 is provided on one side of the slot 202. Obviously, the slot 202 of the left half mold 210 and the slot 202 of the right half mold 220 corresponding to the same insertion portion 260 are distributed on the same side of the mold assembly 200. It can be imagined that the connecting plate 261 and the plug blocks 262 form an integrated structure, and the connecting plate 261 can play the role of a reinforcing rib. When the insertion portion 260 cooperates with the slot 202 for limiting, the structural strength is high and it is not easy to deform.

1, 3 and 4, it can be understood that the limiting structure also includes two elastic ball head plungers 270 installed on the connecting plate 261, and the two elastic ball head plungers 270 both have ball heads that can elastically move left and right. The left half mold 210 and the right half mold 220 are both provided with arc-shaped recesses 203. The arc-shaped recesses 203 on the left half mold 210 are used for the ball head of one of the elastic ball head plungers 270 to be embedded, so as to vertically relatively limit the left half mold 210 and the cover mold 230. The arc-shaped recesses 203 on the right half mold 220 are used for the ball head of another elastic ball head plunger 270 to be embedded, so as to vertically relatively limit the right half mold 220 and the cover mold 230. In this way, through the cooperation of the two elastic ball head plungers 270 and the corresponding arc-shaped recesses 203, the left half mold 210 and the right half mold 210 can be vertically relatively limited. 20 and the cover mold 230 prevent the left half mold 210, the right half mold 220 and the cover mold 230 from being misaligned in the vertical direction during casting or moving the mold, thereby affecting the product quality. Moreover, due to the structural characteristics of the elastic ball head plunger 270, it is only necessary to apply a certain external force to the elastic ball head plunger 270 in the vertical direction to make the ball head of the elastic ball head plunger 270 disengage from the arc-shaped recessed position 203. Therefore, when demolding after molding, it is only necessary to apply a certain upward force to the cover mold 230 to make the ball head of the elastic ball head plunger 270 disengage from the corresponding arc-shaped recessed position 203. At the same time, the insert block 262 will disengage from the slot 202 upward to separate the cover mold 230 from the left half mold 210 and the right half mold 220. After removing the cover mold 230, the left half mold 210 and the right half mold 220 are separated, and the operation is very convenient. It is obvious that the left half mold 210 and the right half mold 220 are arranged opposite to each other on the left and right, and the cover mold 230 is covered on the top of the two. Therefore, under the support of the supporting surface and the action of the mold's own gravity, it is not easy to produce relative vertical displacement between the cover mold 230, the left half mold 210, and the right half mold 220. Therefore, the vertical relative limitation of the three is achieved through the cooperation of the elastic ball head plunger 270 and the arc-shaped recess 203, which is highly practical.

1 and 2 , it can be understood that the front and rear ends of the outer side of the cover mold 230 are provided with limiting structures, the front and rear ends of the outer side of the left half mold 210 and the front and rear ends of the outer side of the right half mold 220 are correspondingly provided with slots 202 and arc-shaped recesses 203, and the limiting effect is good. The structure of the cover mold 230, the left half mold 210 and the right half mold 220 after being molded together is more stable.

3 and 4 , it can be understood that a mounting plate 263 is provided on the side of the connecting plate 261, and a stud 271 is provided on the end of the elastic ball head plunger 270 away from the ball head. The stud 271 extends left and right, and the stud 271 passes through the mounting plate 263 and is locked to the mounting plate 263 by a locking nut 272. The elastic ball head plunger 270 is installed on the mounting plate 263 by cooperating with the stud 271 and the locking nut 272, which is convenient for disassembly and assembly.

1 to 3 , it can be understood that a support 280 is provided on both the left half mold 210 and the right half mold 220, the slot 202 is opened on the support 280, the side wall of the support 280 has a vertically extending mating surface 281, the arc-shaped recess 203 is provided on the mating surface 281, the top of the mating surface 281 has an arc-shaped guide surface 282, the arc-shaped guide surface 282 is used to abut against the ball head of the elastic ball head plunger 270 when the insertion portion 260 is inserted downward into the slot 202, thereby guiding the ball head of the elastic ball head plunger 270 to the mating surface 281, and then the ball head of the elastic ball head plunger 270 can roll along the mating surface 281 until it is aligned with the arc-shaped recess 203 and embedded. Usually, the above-mentioned structural arrangement enables the ball head of the elastic ball head plunger 270 to be very smoothly mated with the corresponding arc-shaped recess 203.

As shown in FIG. 1 , it can be understood that a lifting handle is provided on the upper end surface of the cover mold 230 to facilitate the operator to apply force to the cover mold 230 to lift the cover mold 230 upwards during demolding.

The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
