[0035] In addition, the descriptions involving "first", "second", etc. in the present application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present application.
[0036] Such as Figure 1-6A feces collection box mold for a cat litter box is shown, which includes a front mold assembly, a rear mold assembly and a side core-pulling mechanism; the front mold assembly includes a front template 102, on which a feces collection box convex mold 200 is provided, and the top surface of the feces collection box convex mold 200 has a strip-shaped groove 201; the rear mold assembly includes a rear template 103, on which a feces collection box concave mold 300 is provided. The feces collection box convex mold 200 extends into the feces collection box concave mold 300 to form a feces collection box injection cavity. The bottom surface of the feces collection box concave mold 300 has a strip-shaped protrusion 301, and the strip-shaped protrusion 301 extends into the strip-shaped groove 201; the side core-pulling mechanism includes an inclined guide pillar 400, a slider 401, a first core 402 and a second core 403. The inclined guide pillar 400 is arranged on the front template 102, the slider 401 is slidably arranged on the rear template 103, the slider 401 is provided with an inclined guide groove 404, the inclined guide pillar 400 extends into the inclined guide groove 404, and the first core 402 and the second core 403 are arranged on the slider 401 and both extend into the feces collection box injection cavity. It is easy to understand that the number of side core-pulling mechanisms is two, and the two side core-pulling mechanisms are respectively arranged on the opposite sides of the feces collection box concave mold 300. After the front mold assembly and the rear mold assembly are closed, the feces collection box convex mold 200 and the feces collection box concave mold 300 form a feces collection box injection cavity. The hot melt material flows into the feces collection box injection cavity and cools to form a product. The settings of the strip-shaped protrusion 301, the first core 402 and the second core 403 can form an installation structure on the product, making the product formation very easy. When demolding, the front template 102 and the rear template 103 are separated, and the slider 401 slides outwards under the action of the inclined guide pillar 400, so that the first core 402 and the second core 403 are separated from the product, and thus the demolding of the formed product is very convenient, which is beneficial to improving the demolding efficiency.
[0037] It should be added that the front mold assembly further includes a front mold fixing plate 100 and a front mold backing plate 101. The front mold backing plate 101 is arranged on the front mold fixing plate 100, and the front template 102 is arranged on the front mold backing plate 101. The rear mold assembly further includes a rear mold fixing plate 105 and two cushion blocks 104 which are respectively arranged on both sides of the rear mold fixing plate 105. The rear template 103 is arranged on the cushion blocks 104. A lifter plate 106 is arranged on the rear mold fixing plate 105, and a plurality of ejector pins are arranged on the lifter plate 106. A plurality of pin holes are arranged on both the rear template 103 and the feces collection box concave mold 300, and each ejector pin can slide in each pin hole. When the formed product needs to be ejected, the lifter plate 106 rises under the action of an external driving member, so that the formed product is ejected by the ejector pins to complete the demolding work; cooling water pipes are arranged in both the feces collection box convex mold 200 and the feces collection box concave mold 300 to enable the product to be quickly cooled and formed, which is beneficial to improving the forming rate of the product.
[0038] Please refer to Figure 2, in a possible implementation, an avoidance groove 107 is provided on the front template 102, and one inner side wall surface of the avoidance groove 107 is an inclined surface. The top end of the slider 401 extends into the avoidance groove 107, and the side wall surface of the slider 401 is adaptively fitted with the inner wall surface of the avoidance groove 107. It should be noted that the cross-section of the top of the slider 401 is a right triangle. When the mold is closed, the top of the slider 401 extends into the avoidance groove 107, and the inclined surface of the top of the slider 401 contacts the inclined surface of the inner wall of the avoidance groove 107, which is beneficial to making the cooperation relationship between the slider 401 and the front template 102 more stable. When the slider 401 slides outwards, the contact area between the slider 401 and the front template 102 slowly decreases, improving the overall structural stability of the mold.
[0039] Please refer to Figure 3 , in a possible implementation, a sliding groove 108 is provided on the rear template 103, and the slider 401 is slidably arranged in the sliding groove 108. It should be noted that when the mold is opened, the setting of the sliding groove 108 can provide sufficient moving space for the slider 401 and enable the slider 401 to slide smoothly along the direction of the sliding groove 108. The setting of the sliding groove 108 can prevent the slider 401 from shifting during movement, which is beneficial to the smooth separation of the first core 402 and the second core 403 from the molded product. In addition, the lower end of the inner side wall of the sliding groove 108 extends outwards to form a limiting groove, and the bottom of the side wall of the slider 401 extends outwards to form a limiting protrusion. The limiting protrusion extends into the limiting groove to limit the slider 401, so that the slider 401 can only move back and forth in the sliding groove 108 and cannot move up and down, which is beneficial to improving the stability of the movement of the slider 401.
[0040] Please refer to Figure 3 and Figure 4 , in a possible implementation, an elastic positioning member 500 is provided on the rear template 103. The elastic positioning member 500 extends into the sliding groove 108, and a positioning groove 405 is provided on the bottom wall of the slider 401. The elastic positioning member 500 extends into the positioning groove 405. It should be noted that the number of the positioning grooves 405 is two, and the two positioning grooves 405 are respectively located at both ends of the extreme distance that the slider 401 can move. When the mold is in the closed state, the elastic positioning member 500 extends into one of the positioning grooves 405. When demolding, the slider 401 slides outwards, so that the elastic positioning member 500 slides into the other positioning groove 405. The setting of the elastic positioning member 500 can enable the slider 401 to be quickly positioned during the sliding process.
[0041] Please refer to Figure 5, in a possible implementation, the elastic positioning member 500 includes a fixed block 501, a first spring 502, and a positioning block 503. The fixed block 501 is disposed on the rear template 103. A through hole is provided on the fixed block 501. Both the first spring 502 and the positioning block 503 are disposed in the through hole. One end of the first spring 502 abuts against the rear template 103, and the other end of the first spring 502 abuts against the positioning block 503. The positioning block 503 extends into the positioning groove 405. It should be noted that the fixed block 501 is fixed to the rear template 103 by screws. The positioning block 503 can be telescopic under the support of the first spring 502. When the positions of the positioning block 503 and the positioning groove 405 correspond, the positioning block 503 automatically extends into the positioning groove 405 under the action of the first spring 502 to achieve the purpose of positioning the slider 401.
[0042] Please refer to Figure 4 , in a possible implementation, an elastic limiting member 600 is provided in the slider 401. The elastic limiting member 600 extends into the inclined guide groove 404 to limit the inclined guide post 400 extending into the inclined guide groove 404. It is easy to understand that the slider 401 needs to be driven by the inclined guide post 400 to slide. When the front template 102 is separated from the rear template 103, the inclined guide post 400 is withdrawn from the inclined guide groove 404. Since the elastic limiting member 600 abuts against the inclined guide post 400, the slider 401 can be driven to slide.
[0043] Please refer to Figure 6 , in a possible implementation, the elastic limiting member 600 includes a second spring 601 and a limiting block 602. One end of the second spring 601 abuts against the slider 401, and the other end of the second spring 601 abuts against the limiting block 602. And the top end of the limiting block 602 has a guiding inclined surface 603. It should be noted that when the mold is closed, the inclined guide post 400 needs to enter the inclined guide groove 404. The limiting block 602 can be telescopic under the support of the second spring 601. When the inclined guide post 400 corresponds to the upper opening of the inclined guide groove 404, the inclined guide post 400 can be directly inserted into the inclined guide groove 404. When the inclined guide post 400 does not correspond to the upper opening of the inclined guide groove 404, the inclined guide post 400 can enter from the side opening of the inclined guide groove 404. When the inclined guide post 400 enters from the side opening of the inclined guide groove 404, the elastic limiting member 600 retracts under the abutment of the inclined guide post 400 to avoid the inclined guide post 400, so that the inclined guide post 400 enters the inclined guide groove 404. After extending in, the elastic member limiting member extends again to limit the inclined guide post 400. The setting of the guiding inclined surface 603 can make the limiting block 602 retract more easily under the abutment of the inclined guide post 400.
[0044] Please refer to Figure 4, in a possible implementation, the number of elastic limit members 600 is two, and the two elastic limit members 600 are arranged oppositely, with the tops of the two elastic limit members 600 abutting against each other. It is easy to understand that the movable stroke of the limit block 602 is fixed. By setting two elastic limit members 600, the stroke of the limit block 602 can be shortened by half. Moreover, after the tops of the two limit blocks 602 abut against each other, the two guiding inclined surfaces 603 are connected to form a V-shaped groove, and the inclined guide post 400 can more easily extend into the inclined guide groove 404 from the V-shaped groove, which is beneficial to improving the smoothness of the cooperation between the inclined guide post 400 and the slider 401.
[0045] Please refer to Figure 2 and Figure 3 , in a possible implementation, the number of the stool collection box convex molds 200 and the stool collection box concave molds 300 is two each, so as to form two stool collection box injection cavities. It should be noted that by setting two stool collection box convex molds 200 and stool collection box concave molds 300, the present mold can form two products at one time, which is beneficial to improving the production efficiency of the mold. In addition, it should also be noted that the formed products have two models, and the structures of the two models are slightly different. One has an installation structure on its side wall, and a side core-pulling mechanism is required for forming, and the inclined guide post 400 is essential for convenient demolding after forming. The other does not have an installation structure on its side wall, and the first core 402 and the second core 403 will not obstruct the product during demolding, so the inclined guide post 400 does not need to be set.
[0046] Please refer to Figure 1 , in a possible implementation, a gating system is further included. The gating system includes a first gate 109 and a second gate 110, and the first gate 109 and the second gate 110 are respectively connected to two different stool collection box injection cavities. It is easy to understand that the first gate 109 and the second gate 110 respectively correspond to the two models of the product. When the user only needs to produce one of the models, only the hot melt material needs to be injected into the corresponding gate, and the other does not need to be poured. Moreover, the first gate 109 is arranged on the top surface of the front mold fixing plate 100, and the second gate 110 is arranged on the side surface of the front mold backing plate 101, so that the first gate 109 and the second gate 110 do not interfere with each other. This design enables the present mold to produce two different models of products simultaneously or only produce one of the models, which is beneficial to reducing the manufacturing cost of the mold.
[0047] The above implementation manners are only the preferred implementation manners of the present utility model, and cannot be used to limit the scope of protection of the present utility model. Any non-substantial changes and substitutions made by those skilled in the art based on the present utility model fall within the scope of protection required by the present utility model.
