Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a multi-row continuous demoulding device. Background Art

[0002] Shower heads are commonly used bathroom products in the home. Shower heads are produced with special injection molding molds. The molds generally include moving mold plates, fixed mold plates, moving mold cores, fixed mold cores, sliders and other parts. When molding, all parts are first molded together to form a mold cavity, and then molten plastic is injected into the mold cavity through the pouring system. After the steps of pressure holding, shrinking, cooling and other steps until solidification, the mold is finally opened to separate the molded product. The tail of the shower head body is molded with a threaded section, and there are multiple assembly holes on the threaded body. Due to the different orientations and angles, multiple core pulling and demolding operations are required during demolding, which is prone to mutual interference and jamming problems. Not only is the demolding efficiency low, but it is also not conducive to mold design.

[0003] In view of this, the applicant of this case conducted an in-depth study on the above-mentioned problems and proposed a multi-row continuous demoulding device to solve the above-mentioned problems, which resulted in this case. Utility Model Content

[0004] The utility model aims to provide a multi-row continuous demoulding device, which mainly realizes the continuous demoulding effect of multiple demoulding positions of a shower body.

[0005] In order to achieve the above purpose, the solution of the utility model is:

[0007] The delayed linkage mechanism includes a passive unit arranged on the shovel and an active unit arranged on the slider; the passive unit includes a passive inner limit part and a passive outer limit part arranged to maintain an inner and outer spacing, and the active unit includes an active inner limit part and an active outer limit part located between the passive inner limit part and the passive outer limit part.

[0008] The outer end of the shovel forms the passive inner limit part, and the inner end of the slider is located behind the shovel to form the active inner limit part; the outer end of the shovel is connected to the delay rod, and the end of the delay rod protrudes to form the passive outer limit part, and the slider is formed with the active outer limit part that slides back and forth along the delay rod and is limited by the passive limit part.

[0009] The slider is installed in a slider seat, and a guide groove is provided in the slider seat for the slider to slide back and forth.

[0010] The oil cylinder mechanism is provided with an oil cylinder joint, a joint movable groove is formed at the rear end of the slider, and the oil cylinder joint is movably installed in the joint movable groove; a self-locking block is movably installed at the side wall of the joint movable groove, and a self-locking groove matching the self-locking block is provided on the inner side wall of the slider seat.

[0011] The guide groove is provided inside a wear-resistant part for cooperating with the sliding block.

[0012] A limiting column located outside the slider and used for limiting the slider is arranged in the slider seat.

[0013] After adopting the above scheme, the beneficial effect of the present invention compared with the prior art is that the present invention is used for the linkage core pulling demoulding of the tail inner cavity, the mounting hole formed on the tail and the screw thread section of the shower body, and the core pulling direction of the tail inner cavity is perpendicular to the mounting hole and the screw thread section. During demoulding, the oil cylinder mechanism drives the slider to move outward, and the slider insert is correspondingly demoulded from the tail itself. After that, the oil cylinder mechanism drives the slider to continue to move outward, and with the help of the delayed linkage mechanism drives the shovel to move outward together. With the cooperation of the wedge mechanism, the lower hole slider and the lower screw slider are driven to pull the core out of the mounting hole and the screw thread section respectively. As a result, the present invention realizes the continuous linkage demoulding action of multiple mold cores in different directions on the shower body. The demoulding action is simple, flexible and efficient, and it can well avoid the problem of ineffective demoulding due to spatial interference in narrow spaces. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] This case involves a multi-row continuous demoulding device 3, such as Figure 1-5 As shown, it is arranged on the push plate 200 of the mold, and the push plate 200 is provided with a rear mold core 500, and the shower body 900 is formed in the rear mold core 500. Figure 6 As shown, the demoulding object of the present invention is a shower body 900, which has a tail 907, on which an assembly hole 908 and a threaded section 909 are formed. The core pulling direction of the tail 907 is perpendicular to the core pulling direction of the assembly hole 908 and the threaded section 909.

[0024] The multi-row continuous demoulding device 3 of the present invention mainly comprises a slider 31 and a scraper 32 which are arranged adjacent to each other. The position of the shower body 900 is taken as the inner direction, and the core pulling direction of the tail 907 is taken as the outer direction (the inner and outer directions are Figure 2 The outer end of the slider 31 is connected to a cylinder mechanism 33 that drives it to slide in the inner and outer directions. The inner end of the slider 31 is connected to a slider insert 34, and the slider insert 34 is a mold core portion that extends into the tail 907. The inner end of the shovel 32 is connected to a lower hole slider 35 and a lower screw slider 36 through an inclined wedge mechanism 321. The lower hole slider 35 is a mold core portion that extends into the assembly hole 908, and the lower screw slider 36 is a mold core portion of the formed thread segment 909. The shovel 32 is arranged in linkage with the slider 31, and the slider 31 drives the shovel 32 to slide in the same direction, that is, in the inner and outer directions. With the cooperation of the inclined wedge mechanism 320, the sliding directions of the lower hole slider 35 and the lower screw slider 36 are perpendicular to the inner and outer directions.

[0025] A time-delay linkage mechanism is provided between the shovel 32 and the slider 31, in which the slider 31 delays and drives the shovel 32 to slide together. As a preferred embodiment of the time-delay linkage mechanism, it includes a passive unit provided on the shovel 32 and an active unit provided on the slider 31. The passive unit includes a passive inner limit part and a passive outer limit part arranged to maintain an inner and outer spacing, and the active unit includes an active inner limit part and an active outer limit part located between the passive inner limit part and the passive outer limit part. The active unit is embedded in the middle of the passive unit and slides back and forth between the passive units, driving the shovel 32 to slide with the slider 31 with a delay, and the back and forth sliding stroke of the active unit in the middle of the passive unit corresponds to the delay part.

[0026] As a specific embodiment of the time-delay linkage mechanism, the outer end 322 of the shovel 32 forms a passive inner limit portion, and the inner end 311 of the slider 31 is located behind the outer end 322 of the shovel 32 to form the active inner limit portion. The outer end of the shovel 32 is connected to the delay rod 323, and the end of the delay rod 323 is formed with a flange 3231, which forms a passive outer limit portion. The slider 31 is provided with a matching portion 312. Driven by the slider 31, the matching portion 312 slides back and forth along the delay rod 323, and is limited by the passive limit portion when sliding outward, and the matching portion 312 forms the active outer limit portion.

[0027] The multi-position continuous demoulding device 3 is used for demoulding the tail 907, the mounting hole 908 and the threaded section 909 of the shower body 900. During demoulding, the oil cylinder mechanism 33 is continuously driven to drive the slider 31 to move obliquely outward ( Figure 3 In the first stage, the slider 31 drives the slider insert 34 to be demolded from the tail 907 by core pulling. During the demolding process of the slider insert 34, the matching portion 312 on the slider 31 slides outward along the delay rod 323, and the shovel 32 remains stationary. After the slider insert 34 is demolded, the matching portion 312 moves outward to the limit position with the flange 3231. As the cylinder mechanism 33 continues to drive the slider 31 to move outward, the shovel 32 is driven to move outward synchronously. With the cooperation of the wedge mechanism 321, the shovel 32 drives the lower hole slider 35 and the lower screw slider 36 to be demolded from the mounting hole 908 and the screw segment 909 by core pulling. In this way, the continuous linkage demolding action of multiple mold cores in different directions on the shower body is completed. The demolding action is simple, flexible and efficient, and it can well avoid the problem of ineffective demolding due to spatial interference in narrow spaces. When the device is reset, the oil cylinder mechanism 33 drives the slider 31 to reset, and the delay linkage mechanism cooperates to continuously drive the shovel 32 and the sliding member thereon to reset.

[0028] Preferably, the slider 31 is provided with a slider seat 37, the slider 31 is installed in the slider seat 37, a guide groove 371 is provided in the slider seat 37, the slider 31 is assembled in the guide groove 371 and slides back and forth under the guidance of the guide groove 371. Preferably, a wear-resistant part 38 for matching the slider 31 is also provided in the guide groove 371.

[0029] Preferably, the oil cylinder mechanism 33 is provided with an oil cylinder joint 331, and the oil cylinder joint 331 is assembled with the slider 31 to realize the connection function. In the specific embodiment, the matching portion 312 is formed on the oil cylinder joint 331. The oil cylinder joint 331 and the slider 31 form a slider self-locking mechanism through a movable assembly design. The rear end of the slider 31 is formed with a joint movable groove 313, and the oil cylinder joint 331 can be moved in the inner and outer directions ( Figure 4 The slide block 37 is movably mounted in the joint movable groove 313 (in the left and right directions). A self-locking block 314 is movably mounted on the side wall of the joint movable groove 313, and a self-locking groove 372 matching the self-locking block 314 is provided on the inner side wall of the slider seat 37. The cylinder mechanism 33 drives the slider 31 to move inward through the cylinder joint 331. When the slider 31 moves inward to the right position, the self-locking block 314 moves into the self-locking groove 372 under the push of the cylinder joint 331. The self-locking effect of the slider 31 is achieved through the mutual limiting effect of the two.

[0030] Preferably, a limiting column (not shown in the figure) is provided at the outer end of the slider seat 37, and the limiting column is located outside the slider, and the limiting column is used to limit the outward movement of the slider 31.
